A 68-year-old woman presented with a seven-year history of an asymptomatic grey-black plaque below her left nipple. The lesion was well-defined and 3.5 × 2.5 cm in size. It had a rough surface, uneven pigment distribution and multiple scabs [Figure 1]. There was no palpable breast mass or lump. Lesional biopsy showed isolated basaloid lobules projecting from the lower margin of the epidermis and melanin within the tumour cells. A diagnosis of pigmented superficial basal cell carcinoma was made. Extensive resection was performed on this lesion.
Superficial basal cell carcinoma presents mainly on the trunk as a slowly enlarging, scaly red patch. However, this superficial variant, below the nipple, containing pigment may cause clinical confusion with melanoma and pigmented Paget’s disease.
