Glioblastoma multiforme (GB) is the most aggressive, and the most frequent primary tumor of the brain in adults. Presence of less-differentiated areas which exhibit a small cell morphology and neural immunophenotype is quite uncommon in GBs. Tumor tissue which had been determined in the frontotemporal region of a 61-year-old female patient and evaluated to be consistent with GB radiologically w...

BACKGROUND The aim of presenting this work is to describe a matrix producing carcinoma with anaplastic myoepithelial cell foci, with the coexistence of in situ myoepithelial carcinoma which originated from a sclerosing adenosis. CASE REPORT A 51-year-old perimenopausal woman presented with a hard irregular lump in her left breast. After histological confirmation of malignancy, the patient und...

UNLABELLED Adult testicular granulosa cell tumors are rare sex cord- stromal tumors of which only 45 have been previously reported. As compared with their ovarian counterparts, these tumors may follow a more aggressive course because the proportion of malignant cases is higher. We report here a unique case of a 78-year Caucasian with a left sided adult type granulosa cell tumor with a heterolog...

INTRODUCTION Angiomyofibroblastoma is a tumor which is consists of two components: blood vessels and stromal cells, with always prominent vascular component. Angiomyofibroblastoma is benign tumor, but in literature is reported a case of recurrence and one case with sarcomatous transformation, which shoved that these tumors may rarely be associated with malignant component. CASE REPORT A 78-ye...

Gangliocytic paraganglioma (GP) is an infrequent neuroendocrine tumor usually with three elements as epithelioid cells, spindle-shaped cells and ganglion-like cells, which is generally regarded as a benign tumor. Only a few cases with lymph node metastasis have been reported. Herein, we reported a 47-year-old man of GP with distinct glandular component embedded in the spindle tumor cells in the...

purpose: to recognize affective factors in delivering x-ray contrast agents (which have high atomic number) via gallium carrier to liver or lymphatic neoplasm cells.   materials and methods: since uptake of gallium by liver has been reported in numerous researches, it was bonded with a contrast media (metrizoate). x-ray imaging was done to determine geometric features of liver.   results: radio...

A tumor consisting of an adenocarcinoma component and a neuroendocrine carcinoma component, with each component accounting for at least 30% of the tumor, is defined as a mixed adenoneuroendocrine carcinoma (MANEC). We report a case of MANEC of the pancreas. A 63-year-old man presented with hyperglycemia and was referred to our hospital for further examination. Abdominal contrast-enhanced comput...
