PMID: 35755567.


Primary non-Hodgkin lymphoma of the bone is quite rare, accounting for less than 2% of all lymphomas in adults. We present a unique case of chronic left heel pain in a 34-year-old pregnant woman with a remote history of lower extremity trauma. Unresponsive to conservative treatment, advanced imaging showed an infiltrative soft tissue mass involving the calcaneus and surrounding soft tissues. Biopsy of the area confirmed the diagnosis of Stage I-AE diffuse large B-cell lymphoma. The patient underwent 20 localized radiation treatments to the left heel. Nine years after the diagnosis, the patient remains in remission without signs of disease recurrence. This case report demonstrates that atypical and less common causes of chronic heel pain should be considered in certain clinical scenarios, especially in those unresponsive to conservative treatment.
