It can present as abdominal and extra-abdominal fibromatosis. Extra abdominal deep fibromatosis represent 3.5% of fibrous tissue tumor and 0.03% of all neoplasms. Anterior chest wall forms 10% of Extra abdominal deep fibromatosis cases.
Case history: Patient presented with a progressively increasing large swelling on the chest wall since 2 years. On examination, firm to hard ill defined growth was found. Microscopic examination showed a cellular spindle cell tumour. Strong positivity for VIMENTIN and focal positivity for SMA and DESMIN was seen on Immunohistochemistry. Final Diagnosis of aggressive fibromatosis was made.
