A Unique Presentation of Trichofolliculoma in Amniotic Band Syndrome

This document reports a unique case of trichofolliculoma, a rare hair follicle hamartoma, in a 31-year-old male with amniotic band syndrome, specifically presenting with a type 2 constriction ring on the left arm. The patient exhibited a painful, slowly growing lesion on the scalp for 6 months, characterized by an "erupting volcano" pattern on dermoscopy. Histopathological examination confirmed the diagnosis of trichofolliculoma. This is the first documented instance of trichofolliculoma occurring in conjunction with amniotic band syndrome.
