Iatrogenic superficial temporal artery pseudoaneurysm following cutaneous carcinoma excision

Pseudoaneurysm of the superficial temporal artery is a rare vascular complication that may occur after facial trauma or surgical procedures. We report the case of an 88-year-old patient who presented with recurrent bleeding and a pulsatile temporal mass several weeks after excision of a cutaneous squamous cell carcinoma. Computed tomography angiography revealed a pseudoaneurysm arising from the frontal branch of the superficial temporal artery. Surgical ligation and excision of the lesion were performed, resulting in definitive haemostasis without recurrence. Histopathological examination showed no residual malignancy. This case highlights the importance of considering pseudoaneurysm in the differential diagnosis of delayed bleeding or pulsatile swelling following temporal surgery. Early diagnosis with vascular imaging and prompt surgical management are essential to prevent potentially severe haemorrhagic complications.
