Angioleiomyomas are defined as benign dermal or subcutaneous tumours consisting of smooth muscle cells arranged around vascular channels. Head and neck angioleiomyomas are rarely encountered as they usually occur in the extremities. We report a case of a 71-year-old male, who presented with a 3-month history of a painless lateral neck lump. Ultrasound and computed tomography scans localised the suspicious hypervascular tumour to the right supraclavicular fossa between the two heads of sternocleidomastoid muscle. He subsequently underwent an excisional biopsy, where histological analysis determined that the lateral neck mass was a venous subtype angioleiomyoma. To the best of our knowledge, this is only the third reported case of an angioleiomyoma in the supraclavicular fossa. Although supraclavicular masses are typically synonymous with malignancy, this case report highlights that angioleiomyoma should be considered as a differential diagnosis when investigating patients with a lateral neck lump.
