Dermoscopy of Syringotropic and Folliculotropic Mycosis Fungoides

摘要

Syringotropic mycosis fungoides (STMF) is a rare variant of mycosis fungoides (MF) with prominent involvement of eccrine structures. It typically presents with red/skin-colored/brown papules, patches, scaly plaques, nodules, and lichenification, along with pruritus, hair loss, and poor heat tolerance and sweating [1]. Whether STMF is a subtype of folliculotropic MF (FMF) or a separate entity is still a matter of debate [1]. Most STMF patients have a benign, indolent course and a better prognosis compared to patients with FMF [1]. Histopathology is the gold standard for diagnosis of MF and STMF.
