Marjolin’s ulcers are rare aggressive conditions that arise from chronic skin lesions and diseases. Various cell types may be observed in these lesions; however, squamous cell carcinoma is the most common type. Squamous cell carcinoma due to Marjolin’s ulcer has a greater tendency to metastasize than squamous cell carcinoma due to other causes. This condition occurs primarily on the lower extremities, although a few cases have been reported of it occurring on the scalp. Moreover, cases of penetration of bone and dura mater are observed even more rarely. In this article, we present a rare case of a Marjolin’s ulcer that penetrated the scalp and invaded the bone and dura mater.
