@entity1 @entity5 @entity1222 @entity2281 @entity4896
A 57-year-old @entity1 was admitted to our hospital with an abnormal shadow on chest X-ray film. Computed tomography (CT) scanning demonstrated a low-density, destructive mass on the right 8th rib. The maximum standardized uptake value of the @entity5 measured by positron emission tomography (PET) was 2.9, indicating @entity5 . Wide resection of the @entity5 , including the right 8th rib and the 7th to 8th intercostal muscle, was performed. Chest wall reconstruction was achieved with Composix Mesh. The histologic findings revealed proliferation of histiocytes and eosinophil infiltration. No malignant cells were detected in the @entity5 . Histiocytes stained for @entity2281 protein and @entity4896 , compatible with a diagnosis of @entity1222 ( @entity1222 ). @entity1222 in the ribs is very rare and difficult to diagnose using CT or PET. Tumor biopsy or resection is needed to diagnose @entity1222 .
