Cutaneous Mixed Tumour: A Rare Presentation of a Scrotal Lump Mimicking an Accessory Testis

Abstract

Cutaneous mixed tumour (CMT), also known as chondroid syringoma (CS), is a rare benign tumour composed of epithelial, myoepithelial, and mesenchymal components with an incidence of less than 0.01% of primary skin tumours. It is more common in males and typically presents as a painless slow-growing firm mass in the subcutis of the head and neck region. Genital regions are very rarely involved. We present the case of a 50-year-old male with a 10-year history of an asymptomatic gradually enlarging mass in the upper scrotum. A surgical excision was performed. Microscopic examination showed features of CMT. This case highlights the diagnostic challenges associated with scrotal CMT and surgical management of these lesions. Additionally, we endorse the recommended terminology of CMT used by the fifth edition of WHO Classification of Skin Tumours (2023).
