Synopsis

Basosquamous carcinoma (BSC) is a rare form of skin cancer that comprises less than 2% of nonmelanoma skin malignancies. It is most often identified in the head and neck regions of older White males. BSC has histopathologic features of both squamous cell carcinomas (SCCs) and basal cell carcinomas (BCCs). Its pathogenesis has historically been a subject of debate, but a recent genetic study proved that BSC is a type of BCC that has undergone partial squamatization. Finally, compared to both SCCs and BCCs, BSCs are associated with greater rates of recurrence (up to 45%) and metastasis (approximately 5%-10%). Lymph nodes are the most common site of metastasis, followed by the lungs.
