Cancers of internal organs are not common to metastasize to the skin or subcutaneous tissue and almost none have metastasized to the rectus abdominis, so when you encounter a lesion in a not so common site it is important to consider the complications of not achieving closure of the surgical wound and preventing them due to these types of patients generally tend to have delayed wound healing. In the abdominal wall, with the aim of correcting defects of the aponeurosis, we can perform an anterior or posterior separation of components, intermittent pneumoperitoneum and injection of botulinum toxin. Since 2006, the use of preoperative botulinum toxin began to be studied to relax the insertion of the muscles in their lateral portion, allowing the midline to be approximated in loss of domain hernias.  In this review we present the preoperative approach and preparation of the abdominal wall that we used by injecting botulinum toxin type A (BTA) image guided with ultrasonography, anticipating performing a block resection of skin-muscle-fascia-peritoneum in a 55-year-old female patient with an hypermetabolic mass found in the right rectus abdominis detected with PET-CT in her follow-up due to a history of serous ovarian carcinoma, this to achieve complete lesion removal and fascial closure in the midline.
