Although local recurrence is frequent, metastasis is rare, underscoring the importance of accurate diagnosis and long-term follow-up.<h4>Conclusion</h4>This case highlights the importance of considering PMHE in the differential diagnosis of bone tumors, the utility of FOSB immunostaining in confirming the diagnosis, and the need for long-term follow-up given the high risk of local recurrence. This evidence concerns the gene FOSB and bone neoplasm.
