Chondroid syringoma with squamous metaplasia: Difficult diagnosis on cytology: an interesting case report

Chondroid syringoma or mixed tumor of skin is an uncommon benign skin adnexal tumor of eccrine/apocrine origin constituting nearly 1 % of the total skin tumors. Chondroid syringoma shows marked variation in morphology. Chondroid syringoma with squamous metaplasia is a difficult clinical and cytological diagnosis on cytology because of overlapping cytological features with skin adnexal lesion like pilomatrixoma. We present a case report of 25 year old women, presented with right cheek swelling for duration of three months. The prominent cytological findings were abundant squamous cells in the cytological aspirate along with basaloid epithelial cells component and chondroidmyxoid matrix. This case provides insight in to how Chondroid syringoma with squamous metaplasia because of its unusual cytological findings presents as a diagnostic challenge on cytology.
