Solitary plantar basal cell carcinoma

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.
