title: Pediatric primary follicular mucinosis: further evidence of its relationship with mycosis fungoides.
abstract: Follicular mucinosis (FM) is an uncommon reaction pattern in which the accumulation of mucin in the follicular epithelium is the main pathologic finding. FM may be idiopathic (primary follicular mucinosis [PFM]), in association with mycosis fungoides or cutaneous T-cell lymphoma, or in association with other neoplastic and inflammatory conditions. Herein we report a case of PFM with identical T-cell clone rearrangement at anatomically distinct sites, supporting the idea that some authors have proposed, that FM may represent a low-grade lymphoproliferative disease related to mycoses fungoides with favorable prognosis.
