Abstract A case of neuroblastoma in an adult with extensive metastatic lesions is presented. The initial symptoms and findings suggested idiopathic thrombocytopenic purpura. The blood picture and changes in the clinical picture later led to a diagnosis of acute leukemia. Autopsy disclosed the correct diagnosis, which would have been possible antemortem had the implication of pseudorosette arrangement of immature cells in the bone marrow and the possible occurrence of neuroblastoma in an adult been fully appreciated.

Abstract Accumulation of a lipid, histochemically a phospholipid, in the histiocytes of the splenic pulp was observed in seven patients with thrombocytopenic purpura. Six had classical idiopathic thrombocytopenic purpura with abundant megakaryocytes in the bone marrow. Splenectomy resulted in clinical and hematologic remissions in four of these six, continued thrombocytopenia in the fifth, and in the continued requirement of corticosteroid to maintain a reasonably normal platelet count in the sixth. The seventh patient, who died shortly after splenectomy, had marked hypoplasia of megakaryocytes. Similar lipid accumulation was not seen in more than 700 other spleens, removed for a variety of reasons, reviewed in this study. Platelet phagocytosis has been suggested as a source of the lipid.

Acquired Amegakaryocytic Thrombocytopenia

Acquired amegakaryocytic thrombocytopenia (AAMT) is a rare disease that causes severe bleeding. The pathogenesis and treatment of AAMT have not yet been defined. We report the case of a 60-year-old woman diagnosed with AAMT, who presented with severe thrombocytopenia, gastroin­testinal bleeding, and significantly reduced bone marrow megakaryocytes. The patient was treated with methylprednisolone, cyclosporin, and intravenous immunoglobulin. After 2 weeks of treatment, her platelet count started to increase, and her bone marrow megakaryocyte count had normalized 3 months after diagnosis. At the time of diagnosis, the patient was seropositive for anti-c-mpl antibody but was seen to be seronegative once the platelet count recovered. In contrast, anti-c-mpl antibodies were not detected in the serum of 3 patients with idiopathic thrombocytopenic purpura. This case study suggests that anti-c-mpl antibody plays an important role in the development of AAMT, and that intensive immunosuppressive treatment is required for autoantibody clearance and recovery of megakaryocyte count.

The aim of the present study was to analyse epidemiological, cytological, laboratory and clinical data from canine acute leukemia (AL) cases. The study was conducted from 2009 to 2015, and included 2384 dogs undergoing cytological examination in two veterinary practices in Warsaw. The analysis included dogs in which bone marrow cytology revealed acute leukemia, regardless of its subtype. Data on breed, age, sex, as well as clinical signs and results of haematological examination were collected for every dog. Breed predisposition to acute leukemia was calculated by statistical methods on the basis of the theoretical distribution of canine breeds in Poland. Acute leukemia was diagnosed in 31 dogs (24.7%) undergoing bone marrow cytology, that is, in 1.3% of all the dogs examined by cytology during the study period. The disease was diagnosed mainly in adults, and a strong predisposition was found particularly in German shepherds and Golden retrievers. The median duration of clinical signs from the onset to diagnosis was 14 days. The clinical signs were mostly non-specific (apathy, recurrent fever, lack of appetite), whereas lymphadenomegaly or/and splenomegaly were observed more seldom. Hematology revealed neoplastic leukocytosis in 75% of dogs, whereas anemia and trombocytopenia were observed in 86% and 85% of patients, respectively. Regardless of the leukemia subtype, prognosis was poor. In conclusion, it can be stated that according to current knowledge on canine acute leukemias, bone marrow cytology based on routine staining methods is sufficient for correct diagnosis in a vast majority of cases.
