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

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.

A Case of Lymphocutaneous Sporotrichosis with Unusual Clinical Features / 대한피부과학회지

We report a case of lymphocutaneous sporotrichosis with unusual clinical features in a 62-year-old male patient, who presented with a painless, well-defined psoriasiform plaque and central ulceration on the dorsam of the right hand which progressively spread into the lymphatics draining area. The fully matared lesions produced a chain of firm. mild prickling subcutaneous nodules on both upper extremities probably due to autoinoculation. The biopsy specimen of the lesion showed hyperkeratosis with chronic granulomatous inflammation and PAS-positive fungal spores in the dermis. Sporothrix schenckii was identified using a fungal culture of tissue specimen. The lesions improved with treatment of a topical antifungal agent and KI solution at the dose of 2 g/day for 1 month, but returned to initial cutaneous manifestation due to the patient failing to the treatment.
