title: Bowen's disease concealed by purpura.
abstract: Bowen's disease (BD) is a squamous cell carcinoma in situ characterized by a well-demarcated scaly erythematous thin plaque with an irregular outline. Clinically, BD is frequently misdiagnosed as superficial basal cell carcinoma, patches of dermatitis, psoriasis, lichen planus, actinic keratosis, benign lichenoid keratosis, irritated seborrheic keratosis, viral warts, amelanotic melanoma or melanoma. However, angiosarcoma has not usually been mentioned in the differential diagnosis of BD before. Herein, we describe two cases of BD presenting as purpura on the scalp of the elderly with an initial clinical suspicion of angiosarcoma.
