Brunner's gland hamartoma is an extremely uncommon benign tumor of the duodenum. Most of the lesions are small, asymptomatic and are detected incidentally. It may rarely attain a large size and produces a variety of clinical manifestations. Imaging modalities and endoscopy may locate the lesion, but definitive diagnosis requires histopathological(More)
Pregnancy luteoma is a non-neoplastic lesion of the ovary occurring during pregnancy and is usually discovered incidentally at the time of a cesarean section or during postpartum tubal ligation. An accurate diagnosis is important for the mother and the fetus as it can be confused with ovarian malignancy leading to unnecessary surgery. We report a case of a(More)
Chromosome studies, using bone marrow samples of 26 pretreated children (below 15 years of age) with Acute Lymphoblastic Leukemia were carried out to explore the potentialities of applying chromosomal findings as a prognostic indicator in these patients. Abnormal karyotype was identified in 15 patients (57.6 per cent). The chromosomes frequently involved in(More)
Chromosome studies carried out using lymph nodes of 47 patients with Hodgkin's disease gave analyzable metaphases in 22 patients of which 16 (72.7%) showed chromosome abnormalities. The modal chromosome number ranged from near-diploidy to near-tetraploidy. Chromosomes 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 21 and 22 were involved in(More)
G-banded analysis performed on pretreated bone marrow samples of 36 multiple myeloma patients allowed the identification of clonal chromosome abnormalities. Abnormalities consisting of trisomies, monosomies, translocations, deletions, and marker chromosomes apparently followed a nonrandom pattern. The chromosomes involved in the production of abnormal(More)
OBJECTIVE To assess the efficacy of primary chemotherapy in patients with clinically staged Hodgkin's disease. DESIGN Non randomized study. SETTING Pediatric Oncology Division of Regional Cancer Center. SUBJECTS Twenty nine children with Hodgkin's disease. INTERVENTIONS Chemotherapy was given to 21 patients whose parents agreed for the same. Sixteen(More)
We describe an 8-year-old boy with chronic myeloid leukemia (CML), in lymphoid blast crisis at presentation. Ph chromosome was negative and he remained in complete continuous remission for 3 years. At 10 months from cessation of treatment he presented with involvement of both testes, and bone marrow examination at that time was consistent with CML. Lymphoid(More)
Cytogenetic analysis performed on pretreated unstimulated, bone marrow/peripheral blood samples of 46 adult patients with acute lymphoblastic leukaemia (ALL) showed sufficient metaphases in 39 patients and insufficient metaphases in 7 patients. G-banded karyotype analysis of these 39 patients revealed non-random clonal chromosome abnormalities in 31(More)
Guinea pigs were given ascorbic acid orally in two doses; a low and a high dose. The tissue levels of ascorbic acid-2-sulphate was estimated in these animals after 15 days of feeding and a subsequent deprivation period of 15 days. The specific activity of the enzymes ascorbic acid sulphotransferase and ascorbic acid-2-sulphate sulphohydrolase was studied.(More)
Collagenous spherulosis is a rare entity usually seen in association with benign breast lesions. It is often picked up incidentally with a reported incidence of about 0.2% in cytological material. There are very few reports describing cytomorphological features of collagenous spherulosis. To the best of our knowledge this is the only case reported from the(More)
