A Rare Case of a Giant Tumor of Sebaceous Glands in the Posterior Chest Wall

Sebaceous gland carcinoma is a rare and aggressive tumor that accounts for less than 1% of all cutaneous malignancies. It is classified as intraocular and extraocular and is rarely found in the chest wall. Imaging tests such as Computed Tomography and Magnetic Resonance help to identify the location, size, and evaluation of the involvement of adjacent structures. The treatment is surgical excision, and diagnosis is confirmed postoperatively by the immunohistochemical analysis.
