BACKGROUND/AIM Endometrial carcinoma is the most common malignant neoplasm of the female genital tract in developed countries. Endometrioid carcinoma represents about three-fourths of all endometrial carcinoma. The aim of this study was to examine pathologic parameters, age, and the 5-year survival of the patients with FIGO stage I endometrial carcinoma of endometrioid type and to assess the pr...
Background and Aim: A biliary tract intraductal papillary mucinous neoplasm (IPMN-B), considered a precursor for cholangiocarcinoma, is characterized by intraluminal masses increased mucin secretion that obstructs dilates the tree. 1 The rare cystic tumors, neoplasms of liver (MCN-L), rarely extend into bile ducts, however there are few case reports. 2 Case Report: 54 Years Male, presented with...
A 32-year-old male presented with progressive pure amnesia caused by astrocytoma invading the bilateral medial temporal lobes. Methionine positron emission tomography demonstrated the extent of tumor invasion well. His memory impairment was partially improved by treatment for the astrocytoma. Lesion of the bilateral hippocampus causes memory impairment, but pure memory loss without other associ...
body skeletal scintigraphy performed with 20 mCi (740 Mega Becquerel) of Technetium-99m Methylene DiphosPhonate (MDP) revealed diffusely increased tracer uptake over body of sternum and manubriosternal junction suggestive of neoplastic process. A focal area of benign uptake was also seen over left 2nd costochondral junction (Fig. 3). Contrast enhanced CT study revealed mixed sclerotic and lytic...
Adenoid cystic carcinoma is a malignant neoplasm arising from the salivary glands. The most striking feature of this tumor is that it is locally aggressive, with perineural invasion, tendency to metastasize, high recurrence rates. The parotid gland is the most commonly affected site in the head and neck region, tongue being relatively rare. The current study presents a rare case of 6 years old ...
Angiosarcoma is a rare malignant vascular tumor. Pulmonary involvement is usually attributable to metastasis from other primary sites, primary pulmonary angiosarcoma therefore being quite uncommon. We report a case of angiosarcoma with pulmonary involvement, probably primary to the lung, which had gone untreated for more than two years. We describe this rare neoplasm and its growth, as well as ...
Spontaneous massive haemothorax is uncommon and usually occurs as a result of pulmonary infarction, arteriovenous fistula, neoplasm, ruptured aortic aneurysm, rupture of pleural adhesions or pleural endometriosis. Massive haemothorax in Von Recklinghausen's disease occurs rarely but with potentially fatal results in spite of surgery. We present a case of a spontaneous massive exsanguinating hae...
Cutaneous adenoid cystic carcinoma (CACC) is an extremely rare neoplasm of head and neck region, and is characterized by propensity for local recurrence and perineural invasion. Late distant metastases occur usually to lungs. Although patients with lung metastases from CACC cannot be cured, long-term survival may be possible due to its slow-growing malignancy. We report a case of a 69-year-old ...
adenoid cystic carcinoma (adcc) is a malignant neoplasm, which accounts for 5-10% of all salivary gland tumors (1). about 50% of these tumors originate from intraoral minor salivary glands usually in the hard palate (1). three clinically obvious characteristics of adcc include slow growth rate, perineural invasion and high incidence of distant metastasis (1). the most commonly-affected sites of...
BACKGROUND Although intraductal papillary mucinous neoplasm (IPMN) of the pancreas is acceptable as a distinct disease entity, the concept of mucin-secreting biliary tumors has not been fully established. CASE PRESENTATION We describe herein a case of mucin secreting biliary neoplasm. Imaging revealed a cystic lesion 2 cm in diameter at the left lateral segment of the liver. Duodenal endoscop...
