A case report of aggressive sebaceous carcinoma of the scalp

Malignant pilosebaceous neoplasm of the scalp is a very rare tumor. A 60-year-old man presented with a rapidly enlarging, ulcerated, and firm nodular mass over the scalp for a duration of 3 months. A few months back, the patient noticed a subcutaneous nodule at the same site, and it was reported as sebaceous adenoma on histopathology. The swelling recurred at the same site and was surgically excised and sent for histopathology. A histological diagnosis of sebaceous carcinoma of the scalp was made. On follow-up, there was no recurrence or distant metastasis. Due to the rarity and aggressive behavior of the malignant pilosebaceous neoplasm of the scalp, we present this case along with clinical and histopathological findings.
