Trichofolliculoma represents an uncommon clinical entity.
In reported cases, trichofolliculomas demonstrate no definitive racial predilection.
No definitive sexual predilection is observed in reported cases, although sporadic reports indicate a probable male preponderance.
From published reports, trichofolliculoma appears to primarily be a tumor of adults; however, at least 1 case of congenital trichofolliculoma has been reported.
