A 20-year-old man had developed dermatitis on his scalp and facial hair between his lower lip and chin, his 'soul patch', for one month. He initially presented to urgent care, where the dermatitis was attributed to Herpes simplex infection, for which he was treated with both oral valacyclovir and topical acyclovir. When no change was observed, he consulted his pediatrician, who prescribed oral clindamycin and referred him to dermatology. Physical examination revealed a crusted plaque on an erythematous and edematous base at the lower cutaneous border of the lower lip (Figure 1). Examination additionally revealed an erythematous scaling plaque on the left temporal area with associated flaking, tenderness, and hair loss and left-sided cervical lymphadenopathy. A fungal culture grew Trichophyton mentagrophytes, but a bacterial culture did not grow. Further investigation revealed that he had a dog; however, no other animal contact to account for a fungal reservoir was present. He was successfully treated with oral terbinafine for 6 weeks, plus ketoconazole 2% shampoo and ketoconazole 2% cream with complete reso-lution (Figure 2).

A 34-year-old African-American woman with a past medical history of human immunodeficiency virus (HIV) and hypertension presented to the clinic with a blister that was appearing about once a month on her nose or cheeks over the past 8 months. The blister was occasionally pru- ritic and would resolve spontaneously. At the time of presentation, the patient had only post-inflammatory hyperpigmentation on her nasal dorsum. The patient had photos of the blister on her phone to show what it originally looked like (Figure 1).

The cult of saints in Western Europe developed during the late period of antiquity and the early Middle Ages. Their importance to European society was undeniable; holy medicine was the only hope for people, because there were no doctors. The number of saints had increased over the years, and people sought medical help from them through prayer and other religious practices. Some of the saints became "specialized" in treating various wounds and dermatologic diseases. During our research, we tried to determine whether the cult of saints led to the develop-ment of hospitals that treated skin diseases, as discovered in the Hospital Brother of Saint Anthony. A large number of saints who were patrons of wounds and skin diseases were collected in three studies. In the first report, we presented a great number of saints who were patrons to treat animal bites. The second report presented patron saints of wounds, ulcers, burns, and frostbites; and the third report decsribed saints who treated contagious diseases (such as ergotism, leprosy, and scabies). The phenomenon of holy medicine is part of the history of dermatology and is important due to "specializations," which refer to an understanding of skin diseases and the methods of treating various wounds and dermatologic diseases.

Pseudoxanthoma elasticum (PXE) is an inherited disorder characterized by degradation and fragmentation of elastic fibers and calcium depos- its in the dermis. It clinically manifests as yellow papules or plaques in a cobblestone distribution or "plucked-chicken skin" appearance on the lateral neck and/or flexural areas. In addition, it can also affect the eyes, cardiovascular, and gastrointestinal systems. It is considered as the prototype of ectopic heritable mineralization disorders, usually diagnosed in the second decade of life. The majority of patients are sporadic but recessive, but pseudodominant autosomal forms have been described as well. Mutations affecting the ATP-binding cassette subfamily C member 6 (ABCC6) gene or gamma-glutamyl carboxylase (GGCX) gene lead to PXE. Accumulating evidence in the literature has found that numerous disorders may demonstrate cutaneous PXE-like clinical and/or histologic features without any other systemic evidence of PXE or any genetic documentation of inherited mutations. In this review, we aimed to highlight all the disorders that were reported to exhibit PXE-like clinical and/or microscopic changes and to discuss possible underlying mechanisms leading to such an overlap.
