A case of metastatic chondrosarcoma of the stomach in a 34-year-old female is reported. This patient had been diagnosed as having chondrosarcoma of the right knee and was operated on in 1984. Thereafter, there was repeated local recurrence and operations were performed on multiple metastases, including those of the lung, brain, ovary and spleen. In September, 1990, the patient was readmitted because of advanced anemia. Gastroendoscopy disclosed a firm elevated lesion with central irregular erosion. Histologically, there was cellular atypical cartilage with pleomorphic chondrocytes, which showed the same staining reactions as those in the primary lesion. Therefore this case was diagnosed as metastatic chondrosarcoma. This may be the first documentation of a case of gastric metastasis of chondrosarcoma.
A case of bleeding duodenal varix which was treated successfully with endoscopic injection sclerotherapy (EIS) is reported. The patient developed a hemorrhage from a varix in the descending portion of the duodenum two months after EIS for esophageal varices, and hemostasis was achieved using EIS with an intravericeal injection of 1% polidocanol. The duodenal varix decreased in size after EIS. Two months after EIS, a splenectomy was performed. During a 14-month follow up period after the EIS for the duodenal varix, there was no recurrent bleeding.
A 38-year-old man presented with headache, fever, and double vision associated with right abducens nerve pare-sis. He had neither nuchal rigidity nor visual field defect. Laboratory data revealed elevated erythrocyte sedimenta-tion rate (ESR), eosinophilia, and lymphocytic pleocytosis in the cerebrospinal fluid (CSF). Provocation tests of pituitary hormones showed partial hypopituitarism. Magnetic resonance imaging (MRI) revealed swelling of the hypo-physis and a mass lesion expanding into the right cavern-ous sinus. The supplement dose of dexamethasone for hy-pothalamic hypocortisolism manifested diabetes insipidus. Biopsy, carried out through the transsphenoidal approach, revealed giant cell granuloma. Systemic granulomatous diseases were ruled out, and the lesion was considered to be idiopathic giant cell granulomatous hypophysitis. Right abducens nerve paresis, diabetes insipidus and dysfunction of the anterior lobe were amendedby the treatment with prednisolone for 4 months, and findings of the pituitary gland and stalk were normalized. The present case shows that glucocorticoid has an effect on amendmentof idiopathic giant cell granulomatous hypophysitis. (Internal Medicine 40: 915-919, 2001)
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
