Basosquamous carcinomas (BSCs), which comprise 1.2 –2.7% of skin carcinomas, are aggressive skin tumors that feature histopathologic characteristics of both basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). BSC origin and genetic etiology remain controversial. Chiang and colleagues reported underlying PTCH and SMO mutations in BSCs, su ggesting that Hedgehog signaling drives BSC similar to BCC. Principal component analysis indicated that BSC has greater genetic similarity to BCC than to SCC, supporting the concept that BSCs are derived from BCCs.
