Folliculotropic mycosis fungoides in a child: a rare case

Folliculotropic mycosis fungoides (FMF) is a rare and aggressive form of cutaneous T-cell lymphoma, usually diagnosed in older adults but can occur in children, as shown in a case involving a 12-year-old boy. The boy presented with an asymptomatic, hypopigmented plaque on his face, and histopathological examination confirmed FMF through findings like follicular mucinosis and a predominance of CD4+ lymphocytes. The study emphasizes the critical role of histopathological and immunohistochemical studies in diagnosing FMF and notes that although FMF is aggressive, it often remains in Stage I with treatment, particularly in younger patients.
