BACKGROUND Biliary papillomatosis (BP) is a rare disease entity with a strong malignant potential. It is characterized by multiple papillary adenomas involving both the intrahepatic and extrahepatic biliary tree. BP was considered in the past to be a disease with low malignant potential. However, a current review of the English literature revealed a high rate of malignant occurrence of approxim...

A singularly long-surviving (15 years) disease-free case of a stage II adenosquamous carcinoma of the larynx is described. A review of the literature reveals that prognosis of this aggressive malignant neoplasm is poor (mean 2-3 years free of disease) on account of local recurrences, early cervical lymph node metastasis and distant dissemination. This long survival rate emphasises the importanc...

Necrotizing sialometaplasia is a benign and self-limiting pathological entity that occurs in minor salivary glands, most frequently located on the border between hard soft palate. It has an unclear etiology, being associated with physical, chemical or biological injury, which would produce necrosis due to ischemia of glandular tissue subsequent attempt repair, histologically translates into met...

Malignant fibrous histiocytoma (MFH) is an aggressive soft tissue sarcoma occurring in the late adulthood. It may rarely arise as a primary neoplasm in bone, but usually in the long bones and accounts for less than 1% of the malignant tumors of bone. Its presentation in the facial bones and skull is extremely rare. Malignant fibrous histiocytoma of bone is a highly malignant tumor that recurs, ...

Carcinosarcoma of the uterus (also known as malignant mixed Mullerian tumor, MMMT). Uterine carcinosarcoma is a rare, highly aggressive, rapidly progressing neoplasm associated with poor prognosis that has not significantly improved in past 30 years despite advances imaging and adjuvant therapies. Our case Metachronous cancer where diagnosed two cancers at different time she on etoposide orally...

PURPOSE To evaluate the diagnosis value of integrated positron emission tomography and computed tomography (PET/CT) with lung masses, this study emphasized the correlation between tumor size and maximum standardized uptake value (SUVmax) in selected regions of interest (ROI) of lung masses. MATERIAL AND METHODS A retrospective analysis was performed on 85 patients with solid pulmonary lesions...

Inflammatory myofibroblastic tumor is an uncommon benign neoplasm and its presentation in small bowel is rare. Due to clinical manifestation, laboratory data and radiologic results, there is an increased risk of over diagnosis as malignant tumors particularly malignant lymphoma in childhood therefore may be resulting in wrong therapeutic approach. However pathologic findings could be demonstrat...

A case of intramuscular hemangioma of the right forearm and hand muscle is presented in this study. This tumor may infiltrate the muscle and be misdiagnosed as a malignant neoplasm. The patient, a 14-year-old girl, presented to the clinic with right forearm and hand pain and swelling which began when she was 2 years old and had been gradually increasing in size. Because the mass might have been...
