An Unusual Cause of Hair Loss

Background: Fox-Fordyce disease (FFD) is a relatively rare entity with a typical clinical presentation. Numerous studies have described unifying histopathological features of FFD, which together suggest a defect in the follicular infundibulum resulting in follicular dilation with keratin plugging, subsequent apocrine duct obstruction, and apocrine gland dilation, with eventual extravasation of the apocrine secretions as the primary histopathogenic events in the evolution of the disease. Observations: We describe a case of FFD that developed in a 41-year-old woman 3 months after completing a series of axillary laser hair removal treatments, and we detail the clinical and histopathological changes typical for FFD. Conclusion: Because defective infundibular maturation has been suggested to play a central role in the evolution of FFD, the close temporal relationship of laser hair therapy with the development of FFD suggests a causal role, which we continue to explore.

Sarcoidosis is an antigen‐mediated disease of unknown aetiology characterized by the presence of non‐caseating epithelioid cell granulomas in multiple organs. It involves mainly the lungs, mediastinal and peripheral lymph nodes, eyes and skin. Less frequent but usually severe manifestations can occur in the liver, spleen, central nervous system, heart, upper respiratory tract and bones. Cutaneous lesions of sarcoidosis may be specific, showing histopathologically sarcoid granulomas, or non‐specific, mainly erythema nodosum. Cutaneous lesions are frequently the presentation of the disease and skin biopsy enables early diagnosis. Moreover, some types of lesions have prognostic significance and may help to predict the outcome of the systemic disease.
