S. Medical College and King Edward Memorial Hospital, Mumbai, India Abstract Follicular mucinosis occurring along with angiolymphoid hyperplasia with eosinophils (ALHE) has been described in a 49-year-old male. The patient presented with pruritic hyperpigmented papules and nodules on the vertex and right parietal scalp. There was no any other complaint. Histopathological examination from one of the papule showed prominent blood vessels in the dermis lined by plump histiocytoid endothelial cells that were surrounded by a dense lymphoid infiltrate with numerous eosinophils; these findings are typical of angiolymphoid hyperplasia with eosinophilia. Features of follicular mucinosis were observed in the same section with 3 hyperplastic follicular infundibula containing pools of mucin in the infundibular epithelium. The concurrent occurrence of these 2 distinct histopathological patterns in the same biopsy specimen has been reported rarely.
