Basal Cell Carcinoma (Rodent Ulcer)

Background

Basal cell carcinoma (BCC) in darker-skinned individuals is less common but can present as a shiny, raised bump, sometimes pigmented, or as a flat lesion that may appear brown or black, making it harder to detect. While BCC grows slowly and rarely spreads, it can cause local tissue damage if left untreated, especially on sun-exposed areas like the face and neck. Treatment options include surgical excision, Mohs surgery for more complex cases, cryotherapy, or topical therapies like imiquimod, with early detection key to minimizing cosmetic damage.
