[A case of costal haemangioma]

Abstract

Costal primary tumors are rare and dominated by malignant tumors. Haemangioma of the bone represents only 1% of bone tumors. Costal localization accounts only for 1% of the cases and only about fifty cases have been reported in the literature.

Aim: The authors aim to describe a rare costal tumor, its histological features and the main differential diagnoses.

Observation: The authors describe the case of a 46-year-old woman who presented with chest pain. Radiological findings did not permit a malignant tumor to be ruled out and the treatment consisted of a resection of the posterior arch of the rib. Microscopic examination concluded that the patient had a costal haemangioma and the patient didn't present any recurrence after a six-year follow-up.

Conclusion: The costal haemangioma is a very rare tumor with a debated etiology. Some radiological features are specific such as the "soap bubble" or "honeycomb" aspect. However, the basis for diagnosis remains microscopic examination. These tumors have a good prognosis and no cases of recurrence have been reported following complete resection.
