ABSTRACT
The authors described a rare malignant neoplasm of peripheral nerve sheath, sarcomatous neurillemoma, localized in parotid gland in 72-year female. Findings of the computer tomography, nuclear magnetic resonance and Doppler-ultrasound are presented and discussed. A review of world literature, including 14 cases of this tumor, was made.

A 26-year-old man with primitive neuroectodermal tumour (PNET) is reported. The tumour originated from the cervical spinal cord and was resected partially. Few months later dissemination of the tumour to the meninges occurred. Familial history revealed that the first daughter of the patient had died in age of 14 months three years earlier of a tumour of the right cerebral hemisphere, also diagnosed as PNET.

Diagnostic difficulties in a patient with primary malignant lymphoma of the brain are presented. Computerized tomography scans disclosed, at the beginning, a large mass located in the frontocallosal region, and 15 months later another focus in the cerebellum. Differential diagnostic considerations based on CT and NMR pictures, included infectious diseases, demyelinating diseases also metastatic tumours. The patient was successfully treated surgically, and had than radiotherapy.

A 35-year woman suffering from the tumor of the right groin for 5 years was diagnosed as a diffuse pigmented villonodular synovitis and tenosynovitis following a 7-month follow-up and examinations. Patient was treated with irradiation which produced a subjective improvement but no significant objective response to the treatment was noted.
