Chondroid syringoma, also known as benign mixed tumour of the skin, is a rare benign adnexal tumour. It is a biphasic tumour, composed of both epithelial and mesenchymal components and constitutes <0.01% of all primary skin tumours. It is mostly located in the head and neck region, followed by the hand, foot, axillary region, abdomen, penis, vulva and scrotum. The arm is a rare site of involvement. Making a correct diagnosis of chondroid syringoma is important to guide the clinician in optimal management. We present a case of chondroid syringoma on the left arm in a 37-year-old male. Fine-needle aspiration was performed and diagnosed as chondroid syringoma, which was confirmed on histopathology. This case highlights the importance of considering chondroid syringoma in the evaluation of subcutaneous swellings of the arm and the role of Fine-Needle Aspiration Cytology (FNAC) in diagnosing this uncommon tumour.
