## TL;DR

A rare case of melorheostosis showed extraosseous features resembling a cartilaginous tumor, highlighting the need for combining anatomy and radiology for accurate diagnosis.

## Contribution

Reports a rare case where melorheostosis mimicked a cartilaginous tumor, stressing the importance of anatomo-radiological correlation.

## Key findings

- Melorheostosis can present with extraosseous extension resembling cartilaginous tumors.
- Anatomo-radiological correlation is essential for accurate diagnosis when histology is inconclusive.

## Abstract

Teaching point: Melorheostosis may exceptionally present with extraosseous extension mimicking a cartilaginous tumor, emphasizing the crucial role of anatomo-radiological correlation when histology is confusing.
