Metatypical carcinoma of the skin in a previous cervicofacial flap. A case report

Abstract

Metatypical or basosquamous carcinoma (BSC) is considered a subtype of basal cell carcinoma (BCC). It is often underdiagnosed due to the lack of defined clinical and histological characteristics, leading to misdiagnosis as either BCC or squamous cell carcinoma (SCC). This article presents a case of an 86-year-old male patient with metatypical carcinoma that manifested in a previous cervicofacial flap. There is a high risk of recurrence and metastasis associated with this condition, leading to an unfavorable prognosis for patients. Although there are no standardized therapeutic protocols for this entity, surgical management is the primary approach. No previous reports of metatypical carcinoma in autologous skin grafts were found in the literature.
