eFigure 6–10. A: Ulcer on the nasal tip is the most obvious warning sign for this infiltrative BCC. B: Nodular BCC on the nasal ala of an 82-year-old woman. The nose is a very common location for a basal cell carcinoma. C: Large ulcerated nodular BCC on the mid-chest of a man without housing. The authors excised this in a free clinic located in a church basement. D: Large nodular basal cell carcinoma with an annular appearance on the face of a woman without housing. E: Superficial basal cell carcinoma on the back of a 45-year-old man who enjoys running in the California sun without his shirt. Note the diffuse scaling, thready border (slightly raised and pearly), and spotty hyperpigmentation on the edges. F: Large superficial BCC located on the back. Note the thready pearly border and small areas of pigmentation—both common features in superficial BCCs. G: Sclerosing BCC on the nose. Note the ivory white tumor that extends beyond the pearly pink segment. This took 4 stages of Mohs surgery to remove. H: Sclerosing and infiltrative basal cell carcinoma in a 45-year-old man diagnosed with a shave biopsy. The patient was sent for Mohs surgery because the BCC was aggressive and encroaching on the lower eyelid. (Reproduced with permission from Richard P. Usatine, MD, in Usatine RP, Smith MA, Mayeaux EJ Jr, Chumley HS. The Color Atlas and Synopsis of Family Medicine, 3rd ed. McGraw-Hill, 2019.)
