# A Case of Grade 2 Radiation‑Induced Osteosarcoma

## TL;DR

This case highlights the risk of developing osteosarcoma in areas previously exposed to radiation, even years later.

## Contribution

The paper presents a clinical case emphasizing the long-term risk of radiation-induced osteosarcoma.

## Key findings

- Radiation-induced osteosarcoma can occur years after initial treatment.
- Painful, ossifying masses in irradiated areas should raise suspicion for this condition.

## Abstract

Teaching point: The possibility of a radiation‑induced osteosarcoma should be considered in any painful, ossifying mass occurring within a previously irradiated area, even years after the initial treatment.
