abstract background: abdominal tumors are still a diagnostic problem in children. this study was conducted to assess the presentation and types of childhood intra abdominal tumors in children in shiraz. materials and methods: participants of this historical cohort study consisted of 298 children aged between 1.5 months to 15 years old who were diagnosed with abdominal mass between march 2003 an...

Thiopurine methyltransferase (TPMT)is involved in the metabolism of thiopurines such as 6-mercaptopurine and 6-thioguanine. TPMT activity is significantly altered by genetics, and heterozygous and even more homozygous variant people reveal substiantially decreased TPMT activity. Treatment for childhood acute lymphoblastic leukemia (ALL) regularly includes the use of thiopurine drugs. Importantl...

Choroid plexus carcinoma is a rare intracranial neoplasm, affecting mainly very young children. The commonest site is within the lateral ventricles and the prognosis is very poor. We report a seven month old baby boy who presented with raised intracranial pressure and seizures. Brain CT scan showed large intraventricular mass with calcification and hydrocephalus. Total macroscopic resection of ...

Intraventricular haemorrhage occurred in a patient with a parietal rim-enhancing mass on computed tomographic scan. At operation a brain abscess was identified and removed. Peptostreptococcus and fusobacterium were isolated, possibly of dental origin. The possible sources of this intracranial bleeding are discussed. A neoplasm should not always be considered in the case of a cerebral ring-enhan...

We report a patient with an initial diagnosis of small cell lung cancer treated with prophylactic cranial irradiation (PCI), who subsequently developed a second primary brain neoplasm within the PCI volume. Pathology review was consistent with astrocytoma, WHO grade IV (Glioblastoma Multiforme). After describing our case, we review the literature on the development of a second brain primary aft...

background: clinical and epidemiological variation was seen between the colon cancer (cc) and rectum cancer (rc). so, there is not so much data available about the epidemiological and clinicopathological differences and prognostic factors regarding to cc and cr in iran, we aimed to perform this study. methods: all cases of cc and rc referred to oncology and gastroenterology wards of taleghani g...

account for account for 8% of all primary brain tumours in adults, with most cases being acoustic neuromas, intraparenchymal schwannomas of the brain are rare. Gibson et al. (1) reported the first English-language account of an intraparenchymal intracerebral schwannoma in 1966. Since then, several other cases of this neoplasm have been reported (2, 3). We present a case of an unusual intracrani...

BACKGROUND: Choriocarcinoma is an aggressive neoplasm arising in the body of the uterus. The disease normally spreads to lung and brain. CASE REPORT: A case of malignant trophoblastic disease with brain metastasis, raised intra cranial pressure and small bowel metastasis presenting with acute abdomen is reported. CONCLUSIONS: Malignant transformation in a hydatidiform mole is rare event. Involv...

We report a case of 43-year-old male, presented with sudden onset binocular diplopia on lateral gazes. Ocular examination showed features of ipsilateral one-and-a-half syndrome. Comprehensive systemic work in conjunction with magnetic resonance imaging of the brain illustrated irregular mixed solid and cystic lesions in the brainstem, possibly indicative of brain metastases. Further imaging rev...

In 2000, it was estimated that 16,500 new cases of primary brain tumors would occur in the United States, with 13,000 deaths [1]. Although brain tumors constitute only a small proportion (about 1.4 percent) of overall human malignancies, they carry high rates of morbidity and mortality. More terrifyingly, brain tumors often strike young people. Central nervous system neoplasm is the second most...
