A Case of Primary Nasal CD56+ NK/T cell Lymphoma with Cutaneous Involvement / 대한피부과학회지

Recently a distinct subtype of lymphoma was reported, the natural killer(NK)/T-cell lymphoma, which can involve the skin in a primary or secondary event. NK/T-cell lymphoma is characterized by the expression of the NK-cell antigen CD56. CD56+ lymphoma are further subdivided into nasal and non-nasal NK/T-cell lymphoma.

A Case of Sweet's Syndrome which Mimic Panniculitis Treated with High Dose Potassium Iodide / 대한피부과학회지

Sweet's syndrome, first described in 1964 by Sweet, is characterized by fever, neutrophilic leukocytosis, sudden onset of asymmetric, erythematous, often painful skin lesions, and dense dermal infiltrates of mature neutrophils without signs of vasculitis. The disease responds rapidly to systemic therapy with corticosteroids but recurs in about 25% of the cases. Alternative treatments include potassium iodide, colchine, dapsone, clofazimine, cyclosporin. We report a case of classic sweet's syndrome which was successfully treated with potassium iodide without adverse reactions. 33 year-old male patient became afebrile and symptom free within 24h after starting potassium iodide 900mg/day. The cutaneous eruptions subsided completely in 5 days. He received the drug only for 12days, but there has been no recurrence after 6 months under observation.
