Schwannomas of the gastrointestinal tract are spindle cell tumors originating from peripheral nerve lining Schwann cells, accounting for 2–6% of all mesenchymal tumor and are benign in 98% of cases. Most commonly, they are asymptomatic and discovered incidentallyin elderly. The preoperative diagnosis is challenging because clinical manifestations and CT findings are nonspecific, and biopsies during colonoscopy are in most cases non conclusive, as in our patient, who presented atypical abdominal pain and hematochezia. The best therapeutic option is a complete surgical resection, which will give the definitive diagnosis by confirming S-100 proteins on the immunohistochemical analysis.

An 80-year-old woman presented necrotizing fasciitis on the right flank, requiring debridement. Tomography reported ascending colon neoplasm fistulized to the skin.

Within the primary tumors of the chest wall, sarcomas are the most frequent malignant tumors and can be generated from the cartilage of the ribs, the intercostal muscles, the soft tissues and finally from the bones such as the ribs, the sternum, the shoulder blade or clavicle. Surgical resection of chest wall resections remains the primary treatment for isolated chest wall disease.
