Angiosarcoma is a rare but highly malignant disease. This report presents a 22-year-old
male who has survived a primary angiosarcoma arising from the chest wall. The patient
had been complaining of anterior chest pain for 3 years. CT and MRI revealed a tumor
protruding into the right thoracic cavity from the anterior chest wall but no further
findings. First, the tumor was resected using video-assisted thoracoscopy. The pathological
diagnosis established from a frozen section was of a benign mesothelioma, but this
was changed to angiosarsoma based on findings from a paraffin-embedded specimen. As
a consequence, the third rib and intercostal muscles were resected in a second Operation.
Three years following surgery there was no evidence of tumor recurrence or metastasis.
This case supports a suggestion that not all patients with angiosarcomas experience
the same level of malignancy.
