Abstract
- Bowen's disease is an intraepidermal squamous cell carcinoma also referred to as a squamous carcinoma in situ. Pigmented Bowen's disease is a rare variant and represents less than 2 % of all lesions. Clear cell Bowen's disease, also known as pagetoid Bowen's disease is also rare and characterized by an atypical proliferation of pale tumor cells within the epidermis. We report an unusual case of Bowen's disease in a 50-year-old man which presented as a brown to black colored scaly plaque with crusts on the back. The histopathologic feature of the skin lesion showed Bowen's disease with increased basal pigmentation, dermal melanophages and epidermal clear cells. So we termed this case 'pigmented pagetoid Bowen's disease'
