Chondroblastoma of frontal bone: A tumor in an unusual location in a young child

Clin Neuropathol. 2018 Nov/Dec;37(6):288-291. doi: 10.5414/NP301114.

Abstract

Chondroblastomas are benign tumors of the osteoarticular system, involving long bones of skeletally immature individuals. Chondroblastomas of skull and facial bones are rare, with a predilection for temporal bone. We report the second case of chondroblastoma of frontal bone in world literature in an 8-year-old boy who presented with a painless swelling on the left side of the forehead increasing in size over 1 year. Plain radiography of the skull revealed a circular punched-out lesion in the left frontal precoronal area. Histopathology of the tumor on complete excision showed features of chondroblastoma with increased proliferation. The tumor cells coexpressed vimentin and S100. Complete excision is the recommended treatment with close follow-up for early diagnosis of recurrence. .
