Circumscribed cicatricial alopecia due to localized sarcoidal granulomas and single-organ granulomatous arteritis: a case report and systematic review of sarcoidal vasculitis.

Vasculitis associated with sarcoid granulomas is an uncommon phenomenon. A 72-year-old female presented with an expanding region of circumscribed alopecia and scalp atrophy of 2 months duration. Biopsy showed non-caseating granulomas, dermal thinning, loss of follicles, fibrosis and muscular vessels disrupted by mixed lymphocyte, macrophage and giant-cell infiltrates.

Otophyma: a case report and review of the literature of lymphedema (elephantiasis) of the ear.

Phymas (swellings, masses, or bulbs) are considered the end-stage of rosacea and mostly affect the nose (rhinophyma), and rarely involve the chin (gnatophyma), the cheek (metophyma), eyelids (blepharophyma), or ears (otophyma). Herein, we report the case of a 57-year-old man who developed unilateral enlargement of his left ear over 2 years. Biopsy revealed changes of rosaceous lymphedema associated with Demodex infestation.
