Maladie de Bowen du pied droit

We here report the case of a16-year old patient, with no particular past medical history, presenting, with skin swelling at the level of the forefoot evolving for 02 years, at the Department of Dermatology. Clinical examination showed hard budding cutaneous mass painless on palpation covering the 2, the 3 and the 4, right toes, measuring 4 cm in large diameter. The remainder of the clinical examination was normal, without adenopathies. Skin biopsy was performed at the level of the tumor and histological examination showed carcinoma in situ. Surgical treatment was recommended. Bowen’s disease is a relatively rare squamous intraepithelial carcinoma in situ. It mainly affects adults at any age, with predominance in women. The diagnosis is suspected on the basis of clinical examination, but it is confirmed by the anatomopathological examination.
