Abstract

Follicular mucinosis (FM) is a rare disorder of the skin characterized by follicular degeneration due to the accumulation of mucin within the pilosebaceous unit, with associated inflammatory changes. We report a case of an 11-year-old female with widespread lesions showing distinct clinical and histological features of FM with a brief review of the literature.

Keywords: alopecia mucinosa; follicular mucinosis; mucin; mycosis fungoides.
