Aggressive (epithelioid) osteoblastoma arising in soft tissue

Int J Surg Pathol. 2008 Jul;16(3):308-10. doi: 10.1177/1066896907309577.

Abstract

Aggressive (epithelioid) osteoblastoma arising in soft tissue has never been described. It is important to differentiate this benign osteoblastoma, a potentially locally aggressive tumor, from extraskeletal osteosarcoma. This report describes an aggressive (epithelioid) osteoblastoma arising in a focus of heterotopic ossification in the axilla of a 21-year-old man.
