PY - 2019 T2 - The Color Atlas and Synopsis of Family Medicine, 3e AB - A 71-year-old woman presented with a rapidly growing lesion on her face over the past 4 months (Figure 174-1). The lesion had features of a basal cell carcinoma with a pearly border and telangiectasias (Figure 174-2). Also, the central crater with keratin gave it the appearance of a keratoacanthoma (KA). A shave biopsy was performed, and the pathology showed squamous cell carcinoma (SCC)–KA type. A full elliptical excision with 4-mm margins was then performed.
