Determinants of early referral to healthcare providers, which may be useful for health policy, have not been investigated in pediatric cutaneous leishmaniasis with multivariate analyses. We aimed to explore determinants of early healthcare seeking in children with cutaneous leishmaniasis. Records of 1115 children with cutaneous leishmaniasis admitted to our hospital in Adana, Turkey were reviewed. Effects of age, sex, residential distance, lesion number, and faciocervical onset on early referral were evaluated with multivariate logistic regression analyses. The mean duration of the disease was 12.7 months. Early referral was significantly more likely in patients aged 1-5 and 6-10 years (odds ratio 2.32 and 1.32, respectively) than patients aged 11-18 years. A borderline-significant association was present for faciocervical onset. Early referral in younger children might be due to the fact that the younger the child, the greater the parental concerns about their child's health problems. The rate of late referral in older children may be decreased by some school-based health interventions.

Lichen planus pemphigoides (LPP) is a very rare autoimmune blistering disease associated with lichenoid skin changes. Unna-Thost palmoplantar keratoderma (PKK) is a type of diffuse palmoplantar keratoderma that mostly affects the palms of the hands and soles of the feet. It usually begins in early childhood. We present a unique case of coexistence of LPP, Unna-Thost PPK, and atopic dermatitis (AD). To our knowledge, there are three reported cases of both LPP and Unna-Thost PPK and a few reports of coexistence of Unna-Thost PKK and AD.

Torasemide is a loop diuretic with a molecule that is chemically similar to the sulphonamides described as eosinophilic granulomatosis with polyangiitis (EGPA) triggering drugs. The presented case is probably the first description of torasemide-induced vascular purpura in the course of EGPA. Any diagnosis of vasculitis should be followed by an identification of drugs that may aggravate the disease. A 74-year-old patient was admitted to the Department of Dermatology with purpura-like skin lesions on the upper, and lower extremities, including the buttocks. The lesions had appeared around the ankles 7 days before admission to the hospital and then started to progress upwards. The patient complained on lower limb paresthesia and pain. Other comorbidities included bronchial asthma, chronic sinusitis, ischemic heart disease, mild aortic stenosis, arterial hypertension, and degenerative thoracic spine disease. The woman had previously undergone nasal polypectomy twice. She was on a constant regimen of oral rosuvastatin 5 mg per day, spironolactone 50 mg per day, metoprolol 150 mg per day, inhaled formoterol 12 μg per day, and ipratropium bromide 20 μg per day. Ten days prior to admission, she was commenced on torasemide at a dose of 50 mg per day prescribed by a general practitioner due to high blood pressure. Doppler ultrasound upon admission to the hospital excluded deep venal thrombosis. The laboratory tests revealed leukocytosis (17.1 thousand per mm3) with eosinophilia (38.6%), elevated plasma level of C-reactive protein (119 mg per L) and D-dimers (2657 ng per mm3). Indirect immunofluorescent test identified a low titer (1:80) of antinuclear antibodies, but elevated (1:160) antineutrophil cytoplasmic antibodies (ANCA) in the patient's serum. Immunoblot found them to be aimed against myeloperoxidase (pANCA). A chest X-ray showed increased vascular lung markings, while high-resolution computed tomography revealed peribronchial glass-ground opacities. Microscopic evaluation of skin biopsy taken from the lower limbs showed perivascular infiltrates consisting of eosinophils and neutrophils, fragments of neutrophil nuclei, and fibrinous necrosis of small vessels. Electromyography performed in the lower limbs because of their weakness highlighted a loss of response from both sural nerves, as well as slowed conduction velocity of the right tibial nerve and in both common peroneal nerves. Both clinical characteristics of skin lesions and histopathology suggested a diagnosis of EGPA, which was later confirmed by a consultant in rheumatology. The patient was commenced on prednisone at a dose of 0.5 mg per kg of body weight daily and mycophenolate mofetil at a daily dose of 2 g. The antihypertensive therapy was modified, and torasemide was replaced by spironolactone 25 mg per day. The treatment resulted in a gradual regression of skin lesions within a few weeks. The first report of EGPA dates back to 1951. Its authors were Jacob Churg and Lotte Strauss

Dear Editor, cutaneous chronic graft versus host disease (cGVHD) is a pathological process consisting of donor-derived T-cells aimed at the antigens of the recipient. It exhibits a large range of clinical presentations resembling morphea and deep sclerosis/fasciitis, all characterized by both inflammation and progressive dermal and hypodermic fibrosis (1). Although classic scleroderma-like lesions in cGVHD are nummular or irregular plaques and linear bundles associated with hypo- or hyperpigmentation (2), we report an atypical case with ulcerative presentation. No other case-reports of morphea-like or scleroderma-like cGVHD with an ulcerated appearance after liver transplantation (LT) and magnetic resonance imaging (MRI) correlation have been found in the literature. CASE REPORT Ten months after LT due to an end-stage cirrhosis associated with multifocal hepatocarcinoma (HCC), a 61-year-old man on immunosuppressive therapy with Tacrolimus (1 mg) and Everolimus (10 mg) presented to our clinic for a skin lesion in the right scapular region. We observed a flat ulcerated plaque with areas of sclerosis, minimal necrosis, and well-defined slightly erythematous margins (Figure 1, a). On palpation, the plaque had a hard consistency and was slightly painful. The skin lesion had been preceded by subjective discomfort with stinging sensation for seven months before its onset. Gradually lesion developed starting from a small, flat, oval purplish plaque associated with a progressive increase in pain. Patient denied dysphagia, retrosternal heartburn, Raynaud's phenomenon, arthralgia, and dyspnea. A previous MRI (Figure 2, a,b) showed subcutaneous and muscle edema. Blood tests showed abnormal liver function indexes due to extrahepatic cholestasis, while C-reactive protein, erythrocyte sedimentation rate, and leukocytes were within normal ranges. Self-reactive antibodies were negative. Histological examination (Figure 1, b) identified rare dyskeratotic keratinocytes and basal lymphocyte infiltrate, a dermal dense fibrosis with the disappearance of the skin appendages, and large fibrous septa in the adipose panniculus. It led to the diagnosis of scleroderma/morphea, based on the patient's clinical history. The diagnosis of graft versus host disease scleroderma-like post liver transplant was established. The lesion was treated by topical application of 0.05% clobetasol once a day. We did not use systemic immunosuppressive therapy in order to prevent HCC recurrence. The patient is currently in clinical follow-up to identify worsening or neoplastic degeneration. CASE DISCUSSION Cutaneous cGVHD often presents clinically as an ulcerative evolution in the context of fibrosis and diffuse skin atrophy (2), but very rarely initially appears as a well-delimited ulcerated plaque. Only few cases of ulcer have been found in literature, all in patients undergoing hematopoietic stem cell transplantation (HSCT), which is associated with the highest risk of developing GVHD,

Mucosal melanoma, or so-called mucosal-oral melanoma is a rare but serious diagnostic and therapeutic problem. The "primary mixed" mucocutaneous forms of melanoma, which affect both the mucosa and the adjacent skin, are also particularly problematic and rare. Given that the staging, diagnosis, and treatment of mucosal (oral) melanoma differs from that of cutaneous melanoma, staging in mixed melanoma (primary mucocutaneous melanoma) as well as decisions for each subsequent diagnostic and therapeutic step should be individualized and modified according to the recommendations of the respective two classifications (for cutaneous but also mucosal melanomas), while at the same time or at least to a large extent overlapping with them. In practice, the following paradoxes occur during staging - there are melanomas with the same tumor thickness, but in different stages, which should be treated in a different, consensus-based way. At the same time, it would be appropriate for the surgical interventions to be in accordance with the patient's wishes for minimal trauma/reduced risk of developing facial disproportion. We present the case of a 69-year-old patient with a newly-developed lesion in the area of the mucosa of the upper lip and adjacent skin, which was identified as a primary mucocutaneous form of melanoma after surgical removal. The complex pathogenesis of the disease is discussed herein, emphasizing the role of UV radiation, iatrogenic immunosuppression with mycophenolate mofetil, tacrolimus, and prednisolone (due to severe glomerulonephritis leading to kidney transplantation), as well as the potential possible but speculative pathogenetic role of acetyl salicylic acid, etc. Primary mucosal and mucocutaneous forms of melanoma remain a challenge for clinicians, and steps for their diagnosis and treatment should be an expression of multidisciplinary, consensual solutions.

Positive parental role modeling is a protective factor for adolescent sexual and reproductive health (SRH). Our aim was to investigate parental opinion on adolescents' SRH and vaccination as well as sociodemographic determinants of child-parent communication regarding SRH. This nationally representative cross-sectional telephone survey with a random stratified sample included 500 parents from Croatia (74% mothers), with at least one child under 18 years of age. Stratification was performed by (a) region, and (b) size of settlement. Differences were found between parental beliefs regarding quality, safety, and efficacy of vaccines and potential hazardous effects. Although 95% confirmed their child was vaccinated according to the national program, only 12% vaccinated with optional, self-paid vaccines (excluding human papillomavirus). Almost every third parent was not acquainted with SRH, more commonly fathers. The preferred sources of information for parents regarding SRH were friends, followed by the media and professional healthcare sources, while communication with adolescents was reported by 84% respondents. More than 10% parents claimed that their child did not have accurate knowledge regarding SRH. Our study confirms predominantly positive parental attitudes vaccination and communication with adolescents regarding SRH. We emphasize the importance of effective parental engagement and indicate the need for educational interventions to strengthen knowledge on immunization and SRH.

Hereditary hemorrhagic telangiectasia (HHT), also called Rendu-Osler-Weber syndrome, is a rare autosomal dominant multisystemic vascular disorder, characterized by widespread mucocutaneous teleangiectasias, frequent visceral arteriovenous malformations (AVM) and a tendency for bleeding. This diagnosis should be suspected in all dermatological patients with generalized mucocutaneous vascular lesions at sites of predilection, associated frequent epistaxis and a positive family history. The aim of this paper is to emphasize the importance of a multidisciplinary approach, the role and timely cooperation of dermatologists and otorhinolaryngologists in the early clinical recognition and diagnosis of the disease. We present a family case of a 63-year - old patient with typical clinical features of HHT and long-standing multisystemic complications of unrecognized disease.

Psoriasis is a chronic inflammatory disease associated with a defective epidermal barrier, in which the immune system is already activated in lesional sites of the skin, and it is thus possible that affected individuals can have different immunologic rates of viral response. This is especially important in the era of the novel coronavirus disease (COVID-19) that is affecting the entire world. Patients with psoriasis are often receiving systemic therapy which includes immunosuppressive and biologic therapy, so this new infectious disease has raised concerns among dermatologists regarding psoriasis treatment. Some of the risk factors of psoriasis are obesity, diabetes mellitus, and hypertension - all of which are diseases linked with negative outcomes and higher severity of COVID-19. Psoriasis is mediated by inflammatory cells and proinflammatory cytokines such as IL-17, IL-23, IFN-γ, and TNF-α, and patients with skin diseases have been shown to be more susceptible to COVID-19 infection, but with a less severe disease course. As an anti-inflammatory agent, vitamin D could play a significant role in the future as a possible treatment for reducing the risk and severity of psoriasis and COVID-19. It has been suggested that patients treated with biologic therapy should continue treatment, as it has not been shown to cause severe complications of the COVID-19 disease. Preventive measures, including vaccination, should be taken to minimize the risk of infection and severity of the clinical outcome.

Dear Editor, Morphea profunda (MP) is a chronic autoimmune disease, a subtype of localized scleroderma that presents clinically as local discomfort due to the impairment of skin motility (1). Dermatofibrosarcoma protuberans (DFSP) is a rare soft tissue neoplasm that not only infiltrates the dermis and subcutaneous tissue, but can also affect the muscles and bones with finger-like extensions, usually present on the trunk and the proximal extremities (2). DFSP is known for its indolent clinical course, locally aggressive behavior, and high local recurrence rates, but relatively low risk of metastatic spread (2). DFSP frequently arises in middle-aged adults, affecting both sexes equally with an incidence of 4 per 1,000,000 people (3). We report the case of a 39-year-old female patient who first presented to our clinic at the age of 20 years due to a brownish atrophic coin-sized lesion appearing on the left side of the abdomen. Medical reports indicated that biopsies had been performed previously on 3 occasions, and histopathologic findings confirmed the diagnosis of MP. The aforementioned lesion on the abdomen had been growing slowly over the years, and the patient finally visited our clinic 15 years later after noticing two palpable nodules developing within the affected skin (Figure 1, A, B). Clinical examination revealed an indurated ill-defined plaque measuring 10 cm with partially atrophic surface and 2 centrally located palpable nodules measuring between 3 and 5 mm. A deep biopsy of the lesion was performed, and histopathology and immunohistochemical analysis of CD34 expression confirmed the diagnosis of dermatofibrosarcoma protuberans (Figure 1, C, D). Computed tomography scans of the thorax, abdomen, and pelvic region were subsequently performed, revealing no further disease progression. Complete excision of the tumor was performed and followed by wide scar re-excision due to narrow surgical margins of only 1 mm. No further disease progression or recurrences have been noted during the follow-up, and the patient has been disease-free for one year postoperatively. Although the etiology of DFSP is unknown, trauma has been hypothesized as a predisposing factor. It usually presents on the trunk and the proximal extremities (4). Patients usually report disease progression over a long period of time, ranging from several months to years. The tumor is associated with variable color changes, even proximal skin discoloration, and often presents with a slowly growing indurated dermal plaque or firm nodule attached to the skin (4). Clinically, it can be difficult to distinguish DFSP from a wide number of diagnoses, including morphea, idiopathic atrophoderma, atrophic scar, anetoderma, lipoatrophy, cellular dermatofibroma, fibrosarcoma, malignant fibrous histiocytoma, atypical fibroxanthoma, desmoplastic melanoma, Kaposi sarcoma, and solitary fibrous tumors (5). Immunohistochemistry staining for CD34 cells can be helpful in differentiation, since s

Protein loss is often the result of kidney or intestinal disease (protein-losing enteropathy) and can cause a number of serious, potentially life-threatening complications such as hypotension, thrombocytosis, electrolyte imbalance, and cerebellar ischemia. Recent research suggests an association between extremely severe atopic dermatitis (AD) and allergic enteropathy. An exclusively breastfed 6-month-old infant was admitted to our institution due to failure to thrive, electrolyte imbalance, and severe AD (SCORing Atopic Dermatitis; SCORAD 40). On admission, the infant was in poor general condition, dehydrated, malnourished (bodyweight 4870 g, -3.98 z-score), with exudative erythematous morphs scattered throughout the body. Initial laboratory results showed microcytic hypochromic anemia, hypoalbuminemia, hypogammaglobinemia, thrombocytosis, hyponatremia, high values of total immunoglobulin E (IgE), and eosinophilia. Polysensitization to a number of nutritional and inhalation allergens was demonstrated, and an exclusive amino acid-based formula has been introduced into the diet. During the hospital course, the patient developed superficial thrombophlebitis and methicillin-resistant Staphylococcus aureus (MRSA) bacteremia. Eosinophilia was found in a small intestine biopsy sample. Due to severe hypogammaglobulinemia, skin infections, and bacteremia, the differential diagnosis included primary immune deficiency (STAT3 deficiency, DOCK8 deficiency, PGM3 deficiency, IPEX), but all available immunological tests were unremarkable. Exclusive amino acid-based formula diet was continued in the infant, with topical corticosteroids under wet-dressing therapy and intravenous immunoglobulin replacement therapy. With the gradual improvement of the general condition, the introduction of solid foods was started according to the findings of allergy testing. At 17 months of age, the patient gained weight and his skin status has been improving, although frequent use of topical corticosteroids was necessary. There were no infections, no anemia or thrombocytosis, and albumin and immunoglobulin supplementation were no longer required. The main mechanism of protein loss in infants with extremely severe atopic dermatitis is probably due to damaged skin, and partially due to the eosinophilic inflammation of the small intestine. Immunoglobulin loss, potentiated by physiological or transient hypogammaglobulinemia in infants, poses a very high risk for severe, potentially life-threatening infections.
