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.
