A 45-year-old woman came to the outpatient department with a solitary, slow-growing (5 years) swelling over the scalp. There was no history of pain, discharge or rapid increase in size. Examination revealed a 4x3x2 cm pedunculated, well-circumscribed swelling over the occiput (Figure 1). It was mobile and appeared to be arising from the skin. There was no skin ulceration, punctum or pigmentation. Repeated friction (while combing her hair) had caused minimal excoriation. A diagnosis of papilloma, a soft tissue tumour, was made and the same excised under local anaesthesia. Histopathology revealed the tumour to be a chondroid syringoma-a benign eccrine tumour of the skin appendages.
Benign eccrine tumours include a) syringoma, b)eccrine spiradenoma, c) eccrine poroma, d) cylindroma (turban tumour), e) eccrine acrosporoma, and f) Chondroid syringoma. Chondroid syringoma (cutaneous mixed tumour) is an uncommon well-circumscribed dermal tumour in the head and neck region with an epithelial component, set in myxoid, chondroid and fibrous stroma (a la pleomorphic adenoma). The epithelial component includes solid cords of cells as well as ductal structures, some of which show eosinophilic globules (collagenous spherulosis). Malignant eccrine tumours are also rarely seen.
