Abstract
Basaloid follicular hamartoma is a benign, superficial malformation of hair follicles that can be mistaken both clinical and histopathologically for basal cell carcinoma. Basaloid follicular hamartoma has been linked to a mutation in the PTCH-1 gene, which is part of the same pathway involved in Gorlin-Goltz syndrome. Here we present a 9-year-old patient with an asymptomatic congenital lesion on the forehead, which increased in size over the years. Histopathology showed a basaloid follicular hamartoma associated with follicular mucinosis and inflammation. Gorlin-Goltz syndrome was ruled out by clinical examination.
