Benign cutaneous adnexal tumors in childhood and young adults, excluding pilomatrixoma: review of 28 cases and literature

Benign adnexal tumors of the skin, excluding pilomatrixomas, were identified in 28 patients between the ages of 4 and 20 years with a mean age of 15; 23 women and 5 men. Most lesions were described as papules and they occurred on the face, scalp and neck in 75% of cases. Trichoepithelioma and syringoma accounted for 56% of all neoplasms. Only one patient gave a history of familial trichoepitheliomas. The remaining tumors were examples of syringocystadenoma papilliferum, eccrine acrospiroma, and eccrine and apocrine hidrocystomas. Excisional biopsy constituted the treatment in all cases; only one neoplasm, an eccrine acrospiroma, recurred locally.
