The Perimetric Protuberance-Periosteal Chondroma

Abstract

Periosteal chondroma is an exceptional, benign, gradually progressive cartilaginous neoplasm. Additionally designated as juxtacortical chondroma, sub-periosteal chondroma or soft tissue chondroma, the neoplasm was initially chronicled by Lichtenstein and Hall in 1952 [1]. Characteristically, the lesion arises adjacent to or upon the surface of bone cortex within the sub-periosteal region. The neoplasm arising from hyaline cartilage frequently erodes bone cortex.Periosteal chondroma is appropriately diagnosed with imaging studies and cogent histological features. Morphological distinction of periosteal chondroma from low-grade chondrosarcoma may be challenging. Cytofluorometric analysis of deoxy ribonucleic acid (DNA) ploidy may assist segregation of periosteal chondroma from chondrosarcoma.
