B19 parvovirus (PV) infection is ordinarily resolved with the production of specific antibodies that neutralize virus infectivity for erythroid host cells. Nevertheless persistent infection with B19 PV and pure red blood cell aplasia have been documented. A 27 year-old male. i.v. drug abuser, HIV+ and HCV was diagnosed of pure red cell aplasia. Six months later we had serologic evidence of pers...

maxillary sinus aplasia and hypoplasia are rare conditions that can cause symptoms such as headaches and voice alteration. the majority of patients are asymptomatic, but these conditions must be noticed for importance of differential diagnosis such as infection and neoplasms. conventional radiographs could not differentiate between infl ammatory mucosal thickening, neoplasm, and hypoplasia of t...

aplasia cutis congenita is a rare anomaly presenting with the absence of skin. no definite etiology is available. the most common site is the scalp. we present an instance with acc occurring symmetrically in both sides of the body from chest to flank.

AIM To define the relation between T large granular lymphocyte (T-LGL) leukaemia and pure red cell aplasia in Chinese patients. METHODS Patients with T-LGL leukaemia were identified from a consecutive series of Chinese patients with chronic lymphoproliferative disorders. The diagnosis of T-LGL leukaemia was based on typical morphological and immunophenotypical features, and confirmed by the d...

An 1 8-yr-old female with chronic active The patient’s plasma was cytotoxic for hepatitis developed a severe anemia due erythroblasts. Following splenectomy, a to a lack of red cell production. Her bane remission of the disease occurred. This marrow showed many large proerythrostudy indicates that in some cases the blasts but an almost complete lack of more anemia associated with abundant marro...

Long-term administration of azathioprine is widely used to prevent rejection in organ transplantation and in the treatment of autoimmune diseases. Bone marrow toxicity is a well-known side-effect of azathioprine. Macrocytosis, with or without megaloblastic erythropoiesis in the bone marrow, and (mild) leukopenia are frequently seen [1-4]. Less common effects are anaemia, thrombocytopenia and pa...

Pure white cell aplasia (PWCA) is a rare hematologic disorder characterized by the absence of neutrophil lineages in the bone marrow with intact megakaryopoiesis and erythropoiesis. PWCA has been associated with autoimmune, drug-induced, and viral exposures. Here, we report a case of a 74-year-old female who presented with severe proximal weakness without pain and was found to have PWCA with no...

Acquired pure red cell aplasia (PRCA) has been associated with various lymphoproliferative conditions but its occurrence with Hodgkin's disease is rare. We report a case of PRCA occurring immediately following the completion of induction chemotherapy in a patient with Stage IIIB nodular sclerosing Hodgkin's disease. In vitro erythroid colony studies documented evidence for T cell mediated suppr...
