Abstract:
Tumors of central nervous system are common, especially in children. The most common primary tumor is astrocytoma. Study of microscopic features of astrocytoma could help to diagnose and assess histologically this type of tumor more precisely. Subjects include 122 patients with astrocytoma diagnosed at Department of Pathology, Cho Ray Hospital from June 2003 to June 2004. Histological criteria of these 122 cases were atypical nuclear: 122 cases (100%), endothelial proliferation: 69 (56.5%), necrosis: 36 (29.5%), mitoses: 17 (13.9%), micro cystic: 17 (13.9%), calcification: 6 (4.9%), pseudorosettes: 8 (6.5%). The criteria such as atypical nuclear, endothelial proliferation, necrosis, mitoses, and cellularity are important factors in the diagnosis and histological grading of astrocytoma
