Multidisciplinary Management of Invasive Basal Cell Carcinoma With Intracranial Invasion: A Rare Case Report

The most prevalent kind of skin cancer is basal cell carcinoma (BCC). BCC invasion of the brain occurs quite rarely. Reconstruction approaches along with surgical excision are the gold standard for treating BCC. In this case, we describe a 75 -year -old female patient with highly invasive BCC of the head with subdural invasion. The patient underwent surgery in 2022 in another neurosurgery clinic due to BCC of the head, frequent infection of the skin, and involvement of bone structures by the tumor. The patient presented in 2023 to the neurosurgery clinic at Saint Marina University Hospital with cephalgia, right -side hemiparesis, and a 10 x 10 cm skin defect. On a CT scan, we discovered an invasion of the parietal bones of the skull with an extension to the left subdural space. A craniectomy was performed under general anesthesia, along with hard resection to clear the margins of the BCC that had penetrated the cranial bone. Following the resection of the BCC, reconstruction of the skin defect was performed by a plastic surgeon. Consequently, a satisfactory cosmetic outcome was achieved. Postoperative complications were not observed. The patient was followed up for six months.
