[A case of cerebral microglioma].

The authors present the first national observation of a microgliosarcoma. The patient, a woman of 57 years old, was admitted with the clinical and paraclinical diagnosis of an intracranial mass occupying lesion. Surgical excision was incomplete, and postoperative radiotherapy was undertaken. Posteriorly, lymphoma classification criteria was used to determine the extension of the process. Due to an abnormal retroperitoneal finding in the lymphangiogram the patient was submitted to a laparotomy following staging procedures and diagnosing tuberculous ganglia without lymphomatous lesions. Considerations are made on the identity of the origin of microglia and the reticuloendothelial system and the different nomenclature used to name this tumor. The necessity of a classification of the extension of lesion according to established norms for lymphomas is stressed and therapeutic procedures are proposed.
