Presentation
Left-sided neck swelling and ulcer.
Patient Data











Mildly enhancing, lobulated, broad-based soft tissue density mass (29 x 26 x 24 mm) is observed in the left lateral aspect of the mid-part of the neck. The lesion involves the skin, indenting the subcutaneous layer, and exhibits an exophytic component outside the skin. A small depression is noted in the midpart of the lesion, possibly indicating an ulcer. The adjacent left sternocleidomastoid muscle is mildly compressed; however, the fat plane is maintained.
No cervical lymphadenopathy is observed.
Additionally, cystic lesions are seen on either side of the mandible.

Biopsy of the left neck ulcer revealed basosquamous carcinoma.
Case Discussion
A biopsy was taken from the lesion, and the lesion proved to be basosquamous carcinoma.
Basosquamous carcinoma is an aggressive and rare non-melanomatous skin cancer that represents the characteristics of both basal and squamous cell carcinoma. The head and neck region is the most typical location for basosquamous carcinoma. A wide local excision is the best treatment option for this lesion.
