Abstract
We reported a case of multiple Bowen's disease with adenocarcinoma and squamous cell carcinoma of the lung. He had three brownish erythematous plaques on his left lower leg, left dorsum of the foot and left forearm. The histopathological examination of the lesions showed typical Bowen's disease. He was treated by surgical excision.
It is not solved whether Bowen's disease is a skin marker for internal malignancy, however, we think patients of multiple Bowen's disease are preferably examined their internal malignancy.
