Abstract

Folliculosebaceous cystic hamartoma (FSCH) is a rare cutaneous hamartoma that consists of follicular, sebaceous, and mesenchymal elements. These lesions are mostly seen on the central face and scalp of adults and mostly present as single 0.5-1.5 cm papules or exophytic nodules. A 17-year-old female patient presented at our clinic with the complaint of swelling, pain and discharge in front of the left ear, which had been recurrent since childhood. The lesion was clinically suspected to be an infected preauriculer sinus cyst. After the medical treatment, the patient was operated on with a pre-diagnosis of preauricular sinus cyst. Histopathological findings revealed FSCH. To the best of our knowledge, this is the first reported case of FSCH originating from the preauricular region, located subcutaneously
