Syringocystadenoma Papilliferum: An uncommon diagnosis

Abstract

Syringocystadenoma papilliferum is a benign harmatomatous tumour of apocrine or eccrine sweat gland origin. We report a 30-year-old female who presented with a 24-year history of a slowly growing scalp lesion with a preceding history of trauma to the same region of the scalp as a child. Examination revealed a 2x2 cm tumor in the mid-scalp region, exuding scanty sero-sanguinous fluid on contact. She had an excision biopsy of the lesion following a tentative diagnosis of foreign body granuloma. However, pathologic findings included glandular papillary proliferation connected to the epidermis and lined by columnar cells with oval nuclei with overall impression of Syringocystadenoma papilliferum. She was subsequently reassured and has been on follow-up with no recurrence.
