Niemann-Pick diseases are hereditary neurovisceral lysosomal lipid storage disorders, of which the rare type C2 almost uniformly presents with respiratory distress in early infancy. In the patient presented here, the NPC2 exon 4 frameshift mutation c.408_409delAA caused reduced NPC2 protein levels in serum and lung lavage fluid and the synthesis of an(More)
A three-year-old-boy with generalized Kaposi's sarcoma (KS) is presented. The child died of progressive pulmonary insufficiency on the eighteenth day of the course of his illness, the tenth hospital day. On postmortem examination diffuse KS infiltration was observed in the respiratory and gastrointestinal tracts, lymph nodes, liver, spleen and thymus. The(More)
Eighty-one Turkish children with Burkitt's lymphoma (BL) were observed during a period of 24 years (1968-1992). The diagnosis was established histologically according to WHO criteria. BL represented 48.5% of NHL in this series. The median age of patients was 5 years with a sex (M/F) ratio of 2.3/1. The most common primary site of tumor involvement at(More)
Sixty-three Turkish children with Burkitt's lymphoma (BL) diagnosed over a 10-year period in a single institution were retrospectively analyzed. Burkitt's lymphoma included 41.7% of non-Hodgkin's lymphomas and 17.2% of all childhood malignant solid tumors diagnosed in our department in this duration. The patients studied with BL were aged between 3 and 14(More)
We treated 137 Turkish children with biopsy-proven Hodgkin's disease, followed up between the years 1964 and 1989. Most patients were treated and were in advanced stage with histological subtype of mixed cellularity (67.5%). Radiotherapy (Mantle form) and/or MOPP, ABVD and OPPA combination chemotherapy regimens were used in 75.84% of patients. The follow-up(More)
The aetiology of GS remains obscure and a little is known about the immune competence of these patients. Interestingly, all children with OOGS were from low 'socio-economic status' and showed diminished delayed hypersensitivity reactions and reduced T cell counts (E-R) in our previous observation. We present herewith a preliminary data on evaluation of T(More)
In this study, 82 Turkish children with Hodgkin's disease (HD) between 1 and 14 years of age and diagnosed over a 10-year period were evaluated retrospectively. More than half of the patients (54%) presented with advanced stages of HD. Mixed cellularity (MC) was the most frequent (56.1%) histopathologic type, which was followed by nodular sclerosing (NS,(More)
Purpose. The purpose of this study was to evaluate: (1) the correlation between grade and ploidy or S-phase fraction (SPF), (2) the prognostic value of DNA flow cytometric study in soft tissue sarcomas.Patients /Methods. In all, 47 tissue samples from soft tissue sarcoma patients, surgically treated in the same center, were included. Flow cytometric(More)
The most common primary malignant tumor of the bone is osteosarcoma. Primary involvement of the craniofacial bones in osteosarcoma is relatively rare. The mandible and the maxillae are the most commonly affected bones of the head. Here, we report a rare case of de novo high-grade osteogenic sarcoma of the mastoid region of the temporal bone and discuss the(More)
