Sebaceous carcinoma is a rare malignant tumor derived from the adnexal epithelium of the sebaceous glands. A 58-year-old White male patient attended the stomatology service complaining about a “lump near the third molar.” In the history of the current disease, the patient reported a lesion that appeared approximately 6 months ago and with painful symptoms. Intraoral examination showed a single erythematous tumor in the retromolar region with a smooth surface and ulcerated areas, diffuse borders, irregular, firm, fixed with an infiltrative characteristic, tender, and measuring 2.5 × 2.0 × 1.0 cm. An incisional biopsy was performed with clinical suspicion of squamous cell carcinoma. The histologic sections stained in hematoxylin-eosin and the immunohistochemical reaction showed positivity for epithelial membrane antigen, highlighting the vesicular pattern of the tumor cell cytoplasm. The final result was compatible with sebaceous carcinoma. The patient was referred to the oncology sector and is waiting for cancer treatment.
