Sclerosing syringoid carcinoma of the finger.

We present a case of sclerosing syringoid carcinoma of the finger, a type of eccrine sweat duct malignancy that is rare and mimics the appearance of a benign lesion, but is locally aggressive and has a tendency to recur. It has seldom been reported in the literature. It has a predilection for the head and neck region but is rare in the extremities. We believe this is the second reported case of sclerosing syringoid carcinoma in the finger, after the diagnosis was determined from a histological and immunohistochemical study. The disease presentation and the difficulties encountered during establishment of the diagnosis and planning of the treatment are discussed.
