Clinically detected extra-cranial metastases from glioblastoma multiforme (GBM) are quite rare, with an incidence of <2% reported in the published literature. Among the various reported sites of systemic metastases from GBM, there are few cases of clinically symptomatic bone marrow metastasis. The case of a patient developing systemic dissemination of a GBM is described. A 60-year-old man with GBM who developed back pain, thrombocytopenia and subsequently neurological deficits was found to have extensive bony and bone marrow metastases. Previously reported cases of extra-cranial systemic spread of GBM and attempts made in the literature to explain the possible routes of extra-neural dissemination are reviewed.
Tuberculosis of the rectum is a rare disease. A patient with a miliary pattern of pulmonary tuberculosis had a rectal lesion which proved to be tuberculosis. The patient subsequently developed several opportunistic infections characteristic of acquired immune deficiency syndrome. The clinical, endoscopic, radiologic, and histologic findings of this treatable lesion are presented.
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.
