Basal cell carcinoma is the most frequent skin cancer, generally located in
hair-bearing, sunlight-exposed areas. Basal cell carcinoma usually occurs on the
head and neck, but very rarely on extra-facial locations. We report a case of a
65-year-old woman presenting with a solitary non-healing ulcer on the sole of
the right foot for two years. Histopathological examination showed a typical
nodular basal cell carcinoma, confirmed by positivity to Ber-EP4 on
immunohistochemistry. There was no history of trauma, exposure to noxious
agents, basal cell nevus syndrome, or xeroderma pigmentosum.
