Abstract:
BACKGROUND: Leukemia cutis is readily recognized and documented by biopsy, in contrast. to leukemic involvement in more occult sites. Nine cases of leukemia cutis have been reported in the Korean literatures. However no collective clinical studies have been reported in Korea. OBJECTIVE: We evaluated the differences in patient age and sex, the clinical appearences and distributions of the skin lesions, interval between diagnosis of systemic leukemia and skin involvement, clinical course, and prognosis according to the type of leukemias. METHODS: We carried out a retvospective study of 22 cases of leukemia cutis. Clinical information was obtained from the records of of 22 patients diagnosed at St. Mary's Hospital from 1988 to 1995. All the included cases were well evaluated for their clinical and histopathologic findings. RESULTS: 1. Among 22 patients with leukemia cutis, male patients outnumbered female by 2 to 1 and the mean age was 25.8 years. 2. The clinical appearance of leukemia cutis includes papules, macules, nodules, plaques in all types of leukemia. Ulcerative lesions and vesicles were seen infrequently in leukemia cutis. Leukemia cutis often involved saultiple location of the skin, with no specific predilection of the site. There were no differences in distribution of lesions depending on the types of systemic leukemia. 3. In 68% of the patients with leukemia cutis, the skin lesions developed after the systemic leukemia was diagnosed, and 14% of patients had concomitant, involvement. 18% of patients had skin lesions preceding the diagnosis of systemic leukemia, howevere cytochemical and cytomorphologic studies of bone marrow and peripheral blood smear were not employed at the time of the skin biopsy. 4. Fourteen of 22 patients(64%) did not achieve a complete remission following the diagnosis of leukemia cutis and two of 14 patients without having complete remission could achieve complete remissions with proper anticancer therapy after the diagnosis of leukemia cutis. Total eight patients(36%) achieved a complete remission, then they had a relapse of leukemia in the skin, without having had any skin involvement at the time of the diagnosis of leukemia. 5. Seventeen of 22 patients(77% ) who were being followed up in our series died after leukemia cutis was diagnosed. The mean intervals between diagnosis of leukemia cutis and death was 3.8 months and they died mostly within 1 year. CONCLUSION: The presence of leukemic infiltration in the skin may help the clinician suspect the early diagnosis and relapse of systemic leukemia. It appears that leukemia cutis is associated with a grave prognosis.
