Basal cell carcinoma (BCC) is the most common malignancy. Exposure to sunlight is the most important risk factor. The main clinical subtypes of BCC are nodular, superficial, and morphea form. Combinations of the latter two types with nodular BCC may occur1. Morpheaform BCC accounts for a low proportion of cases, estimated at 5 to 10 percent. It is called sclerosing due its clinical resemblance to a localized scleroderma [1]. Also known as infiltrating BCC, morpheaform BCC is usually more aggressive than nodular and superficial BCC as it tends to exhibit subclinical spread with the potential for extensive local destruction [2].
