A Case of Multiple Bowen's Disease with Atypical Psoriasiform Large Plaque Associated with Internal Malignancies / 대한피부과학회지

ABSTRACT

We report a case of multiple Bowen's disease of probable arsenic origin associated with internal malignancies. A 63-year-old man who had a history of arsenicals injections showed pruritic erythematous 11 8 cm sized psoriasiform plaque on the right flank and multiple keratotic plaques on the trunk and both extremities. He had operation on his bladder due to transitional cell carcinoma. He was found to have a bronchogenic carcinoma by chest X-ray and CT scan. We report this as an interesting case of atypical multiple Bowen's disease manifestating a psoriasiform large plaque associated with internal malignancies of lung and bladder.
