A child with myelodysplastic syndrome with hypocellular fibrosis.

A 9-year-old girl with intractable anemia, rare mucocutaneous bleeding, and pallor was presented. Hemoglobin was 49 g/L; reticulocyte 0.79%, mean corpuscular volume 81 fL, platelet 37×109/L; white blood cell count 3.2×109/L with dysmorphic cells in peripheric blood. Further evaluation revealed 10% cellularity with grade IV reticulin fibrosis, immature, and/or dysplastic hematopoietic cells without sideroblasts, or blast increase in biopsy, Monosomy 8 was found in bone marrow aspiration material using FISH. Vitamin B12, folic acid, hemoglobin electrophoresis, immunoglobulin levels, CD55, CD59, complement 3, 4, abdominal ultrasonography, chest x-ray were normal; diepoxybutane, acid ham, sucrose lysis tests, viral serologies, antinuclear antibody, anti DNA were negative. On diagnosis of "Myelodysplastic Syndrome-refractory cytopenia with hypocellular fibrosis," she received a successful allogeneic BM transplantation from her full matched sibling.
