Abstract
Aggresive fibromatosis is disease in which benign but invasive fibrous tissue proliferates within the deep soft tissue of the trunk or extremities.
A 22-year-old female with a hard tumor of the chest wall was admitted to our hospital. Preoperative examinations, chest tomography, chest CT scan, MRI-CT, bone scintigraphy, etc. led to a presumptive diagnosis of aggressive fibromatosis arising from the deep soft tissue of the chest wall. The tumor was resected with the third, fourth and fifth ribs in a bloc 9 × 10 cm. Reconstruction of the chest wall defect was done with layers of Marlex-mesh. The post-operative course has been uneventful, now 12 months since surgery.
