이개에 발생한 모기질종(Pilomatrixoma) 1예

Pilomatrixoma is a benign skin neoplasm that arises from hair follicle matrix. Pilomatrixoma is a common skin neoplasm in the pediatric polpulation that is often misdiagnosed as other skin conditions. The most prevalent sites of pilomatrixoma in children are the head and neck. The typical presentation is a firm, slowly enlarging, freely mobile, well circumscribed subcutaneous nodule. The diagnosis can generally be made with a clinical examination. Imaging studies are not required unless symptoms or the location of the lesion warrant such diagnostic assessments. The treatment of choice is surgical excision, and the recurrence rate is low. We present a case of pilomatrixoma arising from the auricle, which was treated with surgical excision. (J Clinical Otolaryngol 2005; 16:154-156)
