Baso Squamous Cell carcinoma (BSC) is a rare and potentially aggressive skin neoplasm with features of both Basal Cell Carcinoma (BCC) and Squamous Cell Carcinoma (SCC) with a transition zone and a non-specific clinical presentation. We recently saw a 57-year-old gentleman who presented ulcerated BSC on the right shoulder reaching the acromion with a polymicrobial infection. Microscopical analysis showed a transition zone between BCC and SCC. A periodic acid-Schiff fungus special stain was negative for fungal organisms. BSC represents less that 5% of all non-melanoma skin tumors. The incidence is less than 2% but the true incidence may be higher due to rarity and difficulty of diagnosis. This neoplasm is most commonly found on head and neck on 82-97% of cases. In 2005, the World Health Organization defined BSC as a term used to describe BCC that is associated with squamous differentiation. Prompt recognition of BSC is important in order to aggressively treat and predict the prognosis.
