Abstract:
This report describes the case of a 63 yr old male with an enlarging lesion on the left cheek. Excision biopsy showed a squamous cell carcinoma arising from an eccrine hidrocystoma. The eccrine hidrocystoma showed foci of squamous metaplasia and the sequence of squamous metaplasia complicated by squamous carcinoma is postulated. Squamous differentiation in eccrine neoplasia is discussed.
