Cytologic Features of Chondroid Syringoma in Fine Needle Aspiration Biopsies

Case of chondroid syringoma mimicking a nodular hidradenoma: A diagnostic pitfall on cytopathology

“…6 They are slow growing nodules encountered in the head and neck of adults, lesions usually being 1-3 cm in diameter. 6,7 Index case also presented with a long standing history, but was situated on lower limbs and was of larger diameter. The presence of chondromyxoid material in background with its characteristic fibrillary quality is a diagnostic feature of chondroid syringoma as is the presence of distinct biphasic cell population.…”

“…However reports of cases lacking chondroid differentiation and rather myxoid material is documented in literature. 7,8 Thus it can show broad morphologic patterns, knowledge of which helps prevent potential misdiagnosis. 9,10 Accurate diagnosis of skin tumors is difficult.…”

Chondroid syringoma: A diagnosis by fine needle aspiration cytology

“…[12] It was first described by Billroth in 1859. [3] The incidence of CS among primary skin tumours is 0.01-0.098%.…”

“…[1247] CS are commonly present as slowly growing, painless, firm, subcutaneous or intra-dermal nodules, measuring 0.5-3 cm in diameter, in the head and neck region of middle- and older-aged patients, with male predilection. [12467] The common sites are cheek, nose, or the skin above the lip. [1247] It is often single, but multiple CS have also been reported.…”

“…[12467] The common sites are cheek, nose, or the skin above the lip. [1247] It is often single, but multiple CS have also been reported. [4] CS are often mistaken for other types of skin lesions, such as, dermoid or sebaceous cyst, neurofibroma, dermatofibroma, lipoma, basal cell carcinoma, pilomatricoma, histiocytoma and seborrheic keratosis.…”
