Adenoid Cystic Carcinoma of the Skin

Abstract

Adenoid cystic carcinoma commonly arises from the major and minor salivary glands. Primary cutaneous adenoid cystic carcinoma is extremely rare. The tumour was hard, non-tender, and fixed to the underlying stucture with visible congested veins. Histopathologically, large cell masses with adenoid or cribriform pattern, forming cystic spaces at places were seen. Solid epithelial nests and a few ductal structures were also seen. Plumonary metastases were another unusual feature in our patient perhaps not reported before.
