Background: Desmoid tumor is a rare soft tissues neoplasia characterized by local invasiveness and by a tendency towards local recurrence although not towards metastasization., Discussion: Etiology is not clear. Desmoid tumors originate from the monoclonal proliferation of one mesenchymal cell and develop in the context of fascial, muscular and aponeurotic tissue. They are free of capsule and do not usually metastatize, although they do present a high risk of local recurrence CONCLUSION: In the absence of a systematic data collection and of a clear distinction, in the existing databases, between primitive and recurrent lesions and between lesions of different sites, there are no standard guidelines for a correct management of desmoids., Key Words: Aggressive fibromatos Desmoid tumor, Soft tissue neoplasia.

Introduction: Stapled anopexy is considered the gold standard in treating haemorroidal disease associated to mucosal prolapse, but severe complications have been described. Among these, a minimal anastomotic leakage may lead to gas spreading into surrounding soft tissues., Case Report: We report the case of a 61 year old male who developed pneumoretroperitoneum and pneumomediastinun two days after a Stapled Anopexy. CT scans showed a minimal leakage with no abscess. The patient was successfully treated by bowel rest, antibiotics and total parenteral nutrition, avoiding surgical approach., Conclusion: A minimal anastomotic leakage following Stapled Anopexy, when leading to air diffusion into soft tissues and not associated to abscess or peritonitis may be treated conservatively avoiding ileostomy or colostomy., Key Words: Anastomotic leakage, Pneumoretroperitoneum, Stapled Anopexy.
