Cytodiagnosis of chondroid syringoma-Series of three cases.

Chondroid syringoma is a rare, benign, appendegeal neoplasm. It was initially termed as mixed tumor as it comprises both epithelial cells and chondromyxoid stroma. It usually presents as a slow growing, solitary, painless, subcutaneous, or intracutaneous mass, frequently in the head and neck region. Cytological features usually include the presence of both components, similar to histology but aspiration of only one component or atypical features can pose challenges in diagnosis. According to literature, only a few single case reports describing the cytological features of chondroid syringoma has been published. We report three cases of chondroid syringoma and its differential diagnosis on cytology.
