A Case of Lymphocutaneous Sporotrichosis with Unusual Clinical Features / 대한피부과학회지

ABSTRACT

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.
