N/A Objectives: Sweet`s syndrome(acute febrile neutrophilic dermetosis) is characterized by fever, neutrophilia, erythematous painful cutaneous plaques, a dense dermal infiltrate onsisting of mature neutrophils, and a rapid response to steroid therapy, This condition is clinically important because it is associated with malignancy and it should be one of the differential diagnosis in the febrile immunocompromized patients with skin lesion, In spite of its clinical importance, there was no report on the epidemiologic characteristics of Sweets syndrome in Korean patients so far because of the rarity of Sweet`s syndrome, This study was performed to investigate characteristics and clinical significance of Sweet`s syndrome in Korean patients. Methods : The authors report a case of Sweet`s syndrome associated with acute myelogenous leukemia, and review the other 23 Korean patients with Sweet's syndrome that have been published in the literature. The characteristics of malignancy-associa- ted Sweet`s syndrome are compared with those of Sweet`s syndrome without malignancy association. Results: 1) Twenty-four cases of Sweet`s syndrome were analysed. Male to female ratio was 8:16 and the mean age was 44.8± 11.7 years. In 79% of patients, fever was noticed during the episodes of Sweet's syndrome. The most frequent sites of skin lesions were the upper extremities(83%), followed by face and head(75%), the lower extremities(75%), neck(46%), and trunk (13%). 2) Associated underlying systemic disorders were present in 15(62%) of the patients. The most frequent associations were chronic inflammatory bowel disease in seven patients, hematologic neoplasia in five, and solid neoplasia in one patients. 3) Leukocyte counts(mean 13,400±8,000/mm3) were higher than 10,000/mm3 in 16(67%) of patients. Erythrocyte sedimentation rates(mean 66.8±44.4mm/ hour) were elevated in 18(82%) of patients. 4) Skin lesion improvements were observed within 2 to 5 days from the initiation of steroid therapy. 5) Malignancies were associated in 6 patients. The initial appearance of Sweet`s syndrome lesions preceded or occurred concurrently with the detection of previously unsuspected malignancy in 67%(4 of 6 patients), In malignancy associated Sweet's syndrome, relative male preponderance, older age, and higher leukocyte counts were observed compared with Sweet's syndrome which is not associated with malignancy. There were no statistical significances, however. The erythrocyte sedimentation rate was the only statistically significant parameter. Conclusion: The characteristics of Sweet`s syndrome in Korean patients were similar to the characteristics of their western counterparts. Workup for malignancy seems appropriate far newly diagnosed Sweet`s syndrome patients in case of elevated erythrocyte sedimentation rate, leukocytosis, old age, and male sex
