Superior advancement of the diaphragm and rectus muscle flap as an alternative to prosthetic chest wall reconstruction following the excision of huge lower chest wall tumor

Chest wall reconstruction (CWR) is desirable, especially after the excision of huge chest wall tumor, and using mechanical prostheses for the closure of defects is fraught with some complications. We present a case of a 45-year-old man with a 6-week history of recurrent left-sided lower chest wall mass. Chest examination showed a linear surgical scar 8 cm lower and lateral to the left nipple with an underlying huge mass, whose histology from the previous excisional biopsy revealed dermatofibrosarcoma protuberance. He had the excision of the chest wall tumor and subsequently the superior advancement of the diaphragm and using rectus muscle for the CWR. This method was effective in closing the defect without the known complications.
