Plain-English summary
A 9-year-old female dachshund developed a lump on her upper lip that was diagnosed as a sebaceous epithelioma, a type of skin tumor. After the tumor was surgically removed, it came back 11 months later, and the dog later showed signs of lung and brain metastases, which are rare for this type of tumor. This case highlights that while sebaceous epitheliomas are usually low-grade, some can behave aggressively and spread to other parts of the body. Unfortunately, the dog faced serious complications due to the metastases.

Abstract
Sebaceous epithelioma is a common canine cutaneous neoplasm characterized by a preponderance of basaloid cells with few well-differentiated sebocytes. It is considered a low-grade malignancy, as it may occasionally recur at the excision site; the possibility of lymph node metastasis is anecdotally reported, and distant metastases have never been observed. This case report presents the clinical and pathological features of a sebaceous epithelioma of the upper lip with a highly aggressive behaviour. The patient was a 9-year-old female dachshund that developed local recurrence 11 months after the excision of the primary sebaceous epithelioma and multiple lung and central nervous system metastases 5 months later. The designation epitheliomatous sebaceous carcinoma has been suggested for aggressive sebaceous epitheliomas, although differential criteria are still to be determined.
