Basaloid follicular hamartoma syndrome: acquired sporadic variant with hypothyroidism, hypohidrosis and alopecia, a rare case

Abstract

Basaloid follicular hamartoma is a rare benign malformation of hair follicles, characterised clinically as generalised or localised multiple brown papules mostly on face, scalp and trunk. It may be congenital or acquired with or without any associated disease. Histologically it is composed of epithelial proliferation of basaloid cells with radial disposition enclosed in a fibrous stroma. It is of important consideration because it can be mistaken for basal cell carcinoma both clinically and histologically. Here we report the case of a 51-year-old female with acquired, generalised basaloid follicular hamartomas associated with alopecia, hypothyroidism and hypohidrosis which is an extremely rare disease.

Key Words: Basaloid follicular hamartoma, benign neoplasm, basal cell carcinoma, rare disease, nevoid basal cell carcinoma syndrome.
