Exo-Endophytic Eddies: Inverted Follicular Keratosis

Abstract

Inverted follicular keratosis is denominated as an infrequent, benign neoplasm engendered from hair follicular
infundibulum. Although a neoplasm of indeterminate genesis, inverted follicular keratosis can be considered as a variant
of seborrheic keratosis. Inverted follicular keratosis describes chromatic variants on account of cellular content
incorporated with melanin, particularly with brown and yellow discoloration. Secondary degeneration of the lesions is
extremely exceptional.
