Indian Journal of Dermatology, Venereology, and Leprology, Vol. 77, No. 2, March-April, 2011, pp. 208-210 Letter to the Editor Exfoliative dermatitis with leukemia cutis in a patient with chronic myeloid leukemia: A rare association Anju Raj1, Reena Rai1, Bharath Rangarajan2 1 Department of Dermatology and Veneorology, PSG Institute of Medical Science and Research, Peelamedu, Coimbatore - 641 004, India Correspondence Address: Reena Rai, Department of Dermatology, PSG Institute of Medical Science and Research, Peelamedu, Coimbatore - 641 004, India, drreena_rai@yahoo.co.in Code Number: dv11061 PMID: 21393960 DOI: 10.4103/0378-6323.77471 Sir, A 75-year-old male presented with exfoliative dermatitis in November 2008. During admission, all routine blood investigations were normal expect for the raised white blood cell (WBC) count (32.1 Χ 10 3 /UL) and platelet count (613 Χ 10 3 /UL). Peripheral smear showed normochromic normocytic blood picture with neutrophilic leukocytosis and thrombocytosis. Skin biopsy revealed features suggestive of chronic superficial dermatitis. The patient improved with emollients and was discharged and advised to repeat WBC and platelet count after a month and the patient was lost to follow-up. The patient presented in October 2009 with another episode of exfoliative dermatitis. His investigations were normal except for the raised WBC count (80.1 Χ 10 3 /UL) and platelet count (61.1 Χ 10 3 /UL) and hemoglobin was 9.8 g/dL. Peripheral smear showed marked leukocytosis with anemia with a shift to left, up to the myeloblast stage. A diagnosis of chronic myeloid leukemia (CML) was made. Bone marrow trephine biopsy showed total count increased in number, neutrophils 40%, band forms 17%, metamyelocytes 08%, myelocytes 11%, promyelocytes 08%, and myeloblasts 03%. His liver and renal function tests were normal. Diagnosis of CML was confirmed with immunophenotyping, where polymerase chain reaction (PCR) was found to be positive for BCR-ABL gene. Ultrasound abdomen showed splenomegaly. Biopsy of the skin revealed features suggestive of chronic superficial dermatitis. Fifteen days later, the patient developed multiple tender erythematous ulcerative nodules over both lower limbs [1],[2] [Figure - 1]. Biopsy of the nodule showed angiocentric and diffuse dermal infiltration by atypical myeloid cells of neutrophilic series, suggestive of leukemic infiltrates in the skin [Figure - 2]. So, a diagnosis of luekemia cutis was made. The patient was administered Tablet Imatinib 600 mg/day by the oncologist and a month later there was complete resolution of lesions [Figure - 3]. Exfoliative erythroderma manifests as erythema and scaling of the body, affecting more than 90% of the skin surface. Apart from skin disorders, it is most commonly associated with adult T cell lymphoma, leukemias and myelodysplasias. [3] Erythroderma with leukemia cutis in patients with CML is not reported. Leukemia cutis is an uncommon cutaneous eruption coexistent with leukemia. . Adult T cell leukemia/lymphoma is the commonest cause for leukemia cutis seen in 40-60%, followed by AML (13%). [4],[5],[6] Although specific skin eruptions like leukemia cutis are seen in acute myelomonocytic leukemia and acute monocytic leukemia, [7,8] leukemic cells in the skin are rare in CML with an incidence of 2-8%. [9],[10] The prognosis of leukemia cutis is inconsistent. The prognosis is even poorer after the skin infiltration has occurred. Tumorous infiltration into skin accompanied by blast crisis of CML has a poor prognosis. [6],[9] However, skin infiltration of leukemia cutis responded well to chemotherapy with Imatinib in our patient, with complete resolution within 3 months of therapy. References
