RESUMO
A 24-year-old male presented with a 4 year history of a crusted erythematous papular eruption of the scalp and external auditory meati and a 12 month history of painful perianal ulceration. A diagnosis of Langerhans cell histiocytosis was made and confirmed by skin histology. Extensive investigation revealed no systemic involvement. Rapid improvement occurred after intravenous 2-chlorodeoxyadenosine but relapse of perianal lesions occurred within 5 months. Local radiotherapy to the perianal region resulted in a complete remission sustained over 12 months.

We report an epidemic of sporotrichosis in a south-east Queensland rural community. Sporotrichosis is a fungal infection due to the organism Sporothrix schenckii, typically presenting with cutaneous lesions. Sixteen cases of cutaneous sporotrichosis were seen over a 9 month period in the Darling Downs region of Queensland. All patients had had contact with a batch of mouldy hay presumed to be contaminated by Sporothrix schenckii. Nine of 16 patients were male; the youngest patient was aged 11 and the oldest was 67 years of age. Lymphocutaneous sporotrichosis was seen in 50% of patients; the rest demonstrated the fixed cutaneous form. No cases of disseminated cutaneous or systemic sporotrichosis were seen. One case demonstrated lymphangitis related to sporotrichosis. No apparent difference in the duration to diagnosis was demonstrated to exist between lymphocutaneous or fixed cutaneous types.
