title: Giant benign Chondroid Syringoma in the elbow.
abstract: Chondroid syringoma (CS) is a rarely seen benign tumor rooted in the epithelial and mesenchymal cells of the skin. It is generally localized in the head and neck region and rarely in the extremities. A case is presented here of a giant CS in the rarely seen location of the elbow. A 55-year old male presented at our hospital with the complaint of a slow-growing painless mass in the left elbow. On the left elbow radiograph, mass opacity was observed with a regular border surrounded by a fine radiolucent line within the subcutaneous tissue adjacent to the humerus in the posterior of the elbow. On the contrast elbow MRI mass was observed lobular contours, a regular border and isointensity to muscle in the subcutaneous fat plans. Hypointense linear images were observed in the mass. The lesions demonstrate evident enhancement. An excisional biopsy was performed. A diagnosis of benign CS was made histopathologically. Especially in the differential diagnosis of slow growing cutaneous and subcutaneous nodules in the extremities, CS should feature when fibrous septa are seen on MRI.
