RESUMO
Trichodysplasia spinulosa (TS) is a unique, rare clinical and histological dermatologic entity described mainly in a setting of immunosuppression. It is caused by a novel human polymoavirus, TS-associated polyomavirus. Reduction of immunosuppression and/or anti-viral therapy is the main therapeutic strategies used to treat such cases. We report a biopsy-proven case of TS in a male renal transplant patient who presented to a dermatology outpatient clinic in Montreal, Canada, in 2015. He was managed with valgancyclovir with no obvious response. Subsequently, a trial of topical imiquimod was commenced. Awareness of TS can prompt early diagnosis and management to prevent possible complications.

Discoid or chronic lupus erythematosus is an autoimmune disease that produces skin lesions on the face and scalp. Rarely do lesions present with linear configuration, but when they do, the lesions often follow the lines of embryologic migration. A 24-year-old man presented with a slowly progressing asymptomatic violaceous linear patch running from the root of his frontal scalp to the nasal tip. A Doppler ultrasound and skin biopsy were performed and the histological findings demonstrated characteristic findings of discoid lupus erythematosus. A full physical examination, review of systems and laboratory investigations showed no indication of systemic lupus. High potency topical steroids and calcineurin inhibitors were prescribed along with photoprotection. At 4-month follow-up, all his lesions had mostly cleared. We report here the first case, to our knowledge, of discoid lupus erythematosus with en coup de saber presentation mimicking morphea.
RESUMO
This is a 40-year-old woman with sideroblastic anemia with B cell immunodeficiency, periodic fevers, and developmental delay syndrome, who has genital and extragenital lichen sclerosus on the abdomen and the upper back that have become erythematous and painful during febrile episodes. This report summarizes the published cases of sideroblastic anemia with B cell immunodeficiency, periodic fevers, and developmental delay and highlights associated mucocutaneous features.
