title: [Primary tumors of the central nervous system from material of the Department of Pathological Anatomy--Plovdiv, 1975-1984].
abstract: 8136 deceased at the clinics of the Higher Medical Institute "I. P. Pavlov" for the period of 1975-1984 are studied. 265 of the deceased (3.28%) have tumours of the central nervous system (cns), among which astroglial tumours predominate (73.21%), while nonastroglial tumours represent 26.79%. The largest is the number of astrocytomas II degree--99 cases, followed by astrocytomas III degree--47 cases, multiform glioblastomas--28 cases and astrocytomas I degree--20 cases in accordance with differentiation of astroglial tumours. A larger part of astroglial tumours are localized supratentorially (86.6%) as the mature age is manifested mainly (31-60 years)--61.34% (p less than 0.001). The male sex predominates (61.84%) over the female sex (38.16%) (p less than 0.001) among the decreased with astroglial tumours. The cerebral oedema--64.43% is the most frequent immediate cause for the death of these patients. Menigiomas (42.25%) predominate among 71 patients with nonastroglial tumours, followed by meduloblastomas and ependimomas--15.49% and respectively 12.68%, oligodendrogliomas 8.45%. The remaining histogenetic types of papillomas of choroid plexus, angioreticulomas (hemangioblastomas according to the classification the World Health Organization, 1979), craniopharingiomas are more rarely encountered tumours.
