Gastrointestinal stromal tumors (GISTs) are rare neoplasms of the gastrointestinal tract. One to three percent of GISTs occur in the esophagus. GISTs have a great potential for diffuse intra- abdominal spread and liver metastasis, which are the two most common modes of dissemination. Metastases to other sites, especially the bones and lung, are relatively rare. Never has an esophageal GIST been...

COMPLICATIONS DEFINITION Benign, biologically progressive, highly vascular, high incidence of persistence and recurrence. 0.5% of all neoplasms of head and neck. Hippocrates described a polyp in the nose which weeped blood. Finally Friedberg in 1940 used the term Angiofibroma. Sphenopalatine foramen (Usually Superior lip of the sphenopalatine foramen at the junction of the Pterygoid Process of ...

Anaemia is common among human immunodeficiency virus (HIV)-infected patients. It may be directly attributable to the virus or may be caused by opportunistic infections, neoplasms or drugs that cause either bone marrow suppression or haemolysis. Pure red cell aplasia (PRCA) is an uncommon haematological disorder that causes severe transfusion dependant anaemia. We report a 36 year-old female wit...

Osteoblastoma is a rare neoplasm, accounting for only 1% of the primary bone neoplasms. We report a case of periosteal osteoblastoma, a rare subtype of osteoblastoma. To the best of our knowledge, only 30 cases of periosteal osteoblastoma appear in the English literature. Our case is that of a 41-year-old male with vague intermittent knee pain over a two-year period. Diagnostic imaging revealed...

Indications for endoscopic resection of fronto-ethmoidal osteomas have been progressively expanded thanks to optimization of surgical exposure and the development of dedicated instruments. Curved cutting drills are still suboptimal to treat hard osseous neoplasms of the frontal sinus. We present two patients affected by frontal osteoma treated with an endoscopic procedure using an ultrasonic bo...

This report describes a case of classic severe primary hyperparathyroidism (PH) with clinical presentation that is very infrequent nowadays, which was osteitis fibrosa cystica. As bone scintigraphy demonstrated multiple areas of increasing uptake associated with hypercalcemia, a thorough investigation was conducted to exclude the neoplasms which most frequently are responsible for bone secondar...

Malignant bone tumors in children occur rarely. Estimated annual incidence is 7 cases per 1.000.000 children under the age of 16. Due to its rare occurrence and often unspecific signs and symptoms, a lot of physicians do not consider this diagnosis early enough. Therefore it is not surprising that the majority of patients are referred to the pediatric oncologist when the disease is already in a...

The presence of metaplastic ossification within atypical lipomatous tumor/well-differentiated liposarcoma (ALT/WDLPS) is a rare occurrence. When present, bone formation is most often found in association with a dedifferentiated component arising within the primary tumor. It is important for the radiologist not only to recognize the differential diagnosis of a calcified or ossified soft tissue m...

background esophageal, stomach, and colorectal cancers are commonly lethal gastrointestinal tract (git) neoplasms, causing almost two million deaths worldwide each year. some environmental risk factors are acknowledged; however, genetic defects can significantly contribute to predisposition to git cancers. accordingly, recent works have shown that single-nucleotide polymorphisms (snps) within m...

Metastatic tumors to the temporal bone are very rare. The most common sites of origin of temporal bone metastases are breast, lung, kidney, gastrointestinal tract, larynx, prostate gland, and thyroid gland. The pathogenesis of spread to the temporal bone is most commonly by the hematogenous route. The common otologic symptoms that manifest with facial nerve paralysis are often thought to be due...
