A Rare Case Report of Trichilemmal Carcinoma of Scalp

Dr. Priyanka Manchenahalli Venkatesh Prasad

Abstract: This case report documents the management of a 68-year-old female with trichilemmal carcinoma of the scalp, emphasizing the role of adjuvant radiotherapy following surgical excision. The patient presented with a recurring scalp swelling, initially suspected to be a dermoid cyst. Diagnostic imaging identified a well-circumscribed lesion, which upon surgical excision and histopathological examination, was diagnosed as trichilemmal carcinoma. The patient underwent successful excision and local reconstruction. The recurrence of the tumor with close surgical margins necessitated adjuvant radiotherapy. The treatment, involving a 60Gy dose via 3DCRT technique, was well-tolerated, and the patient remained free of local, regional, or distant recurrences over a two-year follow-up. This report underscores the importance of clear surgical margins in managing trichilemmal carcinoma and suggests that adjuvant radiotherapy can be a vital component of treatment for local control, especially in cases of local recurrence and close margins.
