The present case report describes a rare case of recurring lumps on the external ear in a 46‑year‑old Chinese male with a history of >10 years, who presented with large irregular red lumps on the right temple and with lung and skull base metastasis. The patient had a lesion in the right auricle and experienced recurrence following surgical resection. A thorough systemic evaluation revealed no other obvious abnormalities. The patient was diagnosed with adenoid cystic carcinoma (ACC), a slow‑growing form of high‑grade adenocarcinoma, and refused any further treatment at the present hospital (The First Affiliated Hospital of Army Medical University). At 2 years post‑follow‑up, the patient had become more frail but was in good spirits. The present study indicated that ACC is a low‑grade and commonly slow‑developing malignancy that primarily arises from a salivary gland, with recurring and metastatic characteristics.
