Currently, ulcerative sexually transmitted infections, including syphilis, herpes simplex virus (HSV), lymphogranuloma venereum (LGV), chancroid, donovanosis and, more recently, monkeypox (MPOX), represent a growing challenge for health care professionals. The incidence of syphilis and LGV has increased in recent years in Spain. Additionally, HSV, syphilis and chancroid can also increase the risk of HIV acquisition and transmission. The population groups most vulnerable to these infections are young people, men who have sex with men (MSM) and commercial sex workers.It is important to make a timely differential diagnosis since genital, anal, perianal, and oral ulcerative lesions may pose differential diagnosis with other infectious and non-infectious conditions such as candidiasis vulvovaginitis, traumatic lesions, carcinoma, aphthous ulcers, Behçet's disease, fixed drug eruption, or psoriasis. For this reason, the dermatologist plays a crucial role in the diagnosis and management of sexually transmitted infections.This chapter presents the main epidemiological, clinical and therapeutic features associated with these infections.

Background and objective: subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare cytotoxic T-cell lymphoma with indolent behavior, mostly present in women and associated with immunological diseases whose pathogenic background is still poorly understood. SPTCL is associated with lupus erythematosus panniculitis (LEP) and histologically misdiagnosed.

Objectives: the aim of our study was to identify mutations affecting the pathogenesis of both SPTCL and LEP.

Materials and methods: we studied a total of 10 SPTCL and 10 LEP patients using targeted Next Generation Sequencing and pyrosequencing. Differences in gene expression between molecular subgroups were investigated using NanoString technology. Clinical data were collected, and correlations sought with the molecular data obtained.

Results: the mutational profile of SPTCL and LEP is different. We identified fewer pathogenic mutations than previously reported in SPTCL, noting a single HAVCR2-mutated SPTCL case. Interestingly, 40% of our SPTCL cases showed the pathogenic TP53 (p.Pro72Arg) (P72R) variant. Although cases showing HAVCR2 mutations or the TP53 (P72R) variant had more severe symptomatic disease, none developed hemophagocytic syndrome (HPS). Furthermore, TP53 (P72R)-positive cases were characterized by a lower metabolic signaling pathway and higher levels of CD28 expression and Treg signaling genes. In addition, 30% of our cases featured the same mutation (T735C) of the epigenetic modificatory gene DNMT3A. None of the LEP cases showed mutations in any of the studied genes.

Conclusions: the mutational landscape of SPTCL is broader than previously anticipated. We describe, for the first time, the involvement of the TP53 (P72R) pathogenic variant in this subgroup of tumors, consider the possible role of different genetic backgrounds in the development of SPTCL, and conclude that LEP does not follow the same pathogenic pathway as SPTCL.

Background and objectives: Patient-reported outcomes (PROs) are outcomes evaluated by patients based on their perception of their disease and treatment. The objective of PROs is to determine antipsoriatic treatment-related adherence, quality of life (QoL) and satisfaction.

Materials and methods: We conducted an observational cross-sectional, prospective, and single-center study in which PROs surveys were conducted on adherence (Morisky-Green [MG] test), treatment satisfaction (Spanish Questionnaire of Treatment Satisfaction in Psoriasis [CESTEP]) and QoL (Skindex-29 and DLQI). Additional variables include: PASI, BSA.

Statistical analysis: Jamovi®2.3.26.

Results: A total of 100 surveys were conducted. Based on the MG questionnaire, we found that 75% (75/100) of patients were adherent vs 94% (94/100) from the dispensation records. Regarding CESTEP, a mean score of 7.4 ± 7.7 (close to maximum satisfaction 0) was obtained, while DLQI yielded a score of 2.6 ± 4.6 (indicating a small effect on QoL), and SKINDEX-29 a score of 14.6 ± 15.4 (68% indicating mild (< 5) or very mild (6-17) impact according to Nijsten et al.). Based on CESTEP a p.Rho Spearman value of 0.338 (p = 0.004) was obtained in relation to PASI when the study was conducted with a BSA of 0.255 (p = 0.050), DLQI results of 0.508 (p < 0.001) and Skindex-29 results of 0.397(p < 0.001). At the time of the study, the correlation matrix between DLQI result and PASI was 0.365 (p = 0.002) with a BSA of 0.347 (p = 0.007). Skindex-29 results with PASI were 0.380 (p = 0.001) and with BSA, 0.295 (p = 0.022).

Conclusions: Patients on therapy exhibit a good QoL, high adherence and satisfaction with their treatment. A significant correlation was seen among satisfaction, QoL, and PASI-BSA at the time of the study.
