E. Matyja et al., MENINGIOMAS AND GLIOMAS IN JUXTAPOSITION - CASUAL OR CAUSAL COEXISTENCE - REPORT OF 2 CASES, The American journal of surgical pathology, 19(1), 1995, pp. 37-41
Two cases of meningioma and glioma established in biopsy material from
one or more than one operation are reported. In these cases, an origi
nally benign meningioma was followed by the development of anaplastic
astrocytoma in close juxtaposition to the site of first operation. The
close juxtaposition of two histologically different tumors suggested
that one of them might lead to local proliferation and independent gro
wth of the other.
