title: Chondroid syringoma of the axilla: An unusual tumor diagnosed by fine needle aspiration.
abstract: Chondroid syringoma (CS) is a rare benign adnexal tumor of the skin with a resemblance to pleomorphic adenoma of salivary gland, most commonly involving the head and neck region. In the present literature, reports of the cytologic appearance of CS are scarce as it is rarely encountered by fine needle aspiration (FNA). A 67-year-old woman presented with a 1 year history of a 1 cm subcutaneous nodule in the right axilla. FNA biopsy was performed revealing an epithelial-mesenchymal biphasic neoplasm suggesting CS. Surgical excision confirmed the diagnosis and demonstrated extensive ossification, an extremely rare feature, with only seven reported cases, all located on the head. CS is a rare benign adnexal tumor of the skin, often overlooked due to its unremarkable clinical presentation. FNA is a reliable tool for the diagnosis of CS and helps guide optimal surgical management.
