Desmoid-type Fibromatosis of the Splenic Hilum: A Rare Tumor at an Unusual Location.

Desmoid-type fibromatoses (DTFs), also known as desmoid tumors, are benign but infiltrative neoplasms that often appear next to previous surgical site. Intra-abdominal tumors usually involve the mesentery, but splenic hilum is an unusual localization. We present a case of a desmoid tumor of the splenic hilum laparoscopically resected in a 70-year-old male with a previous history of chromophobe renal cell carcinoma and ocular spindle melanoma. Although benign, desmoid tumors might be infiltrative and produce serious complications. Treatment remains controversial, ranging from surgery and medical therapies to observation. Management of DTF must be individualized, considering the risk of complications and recurrence.

Duodenal Rupture after Blunt Abdominal Trauma by Bicycle Handlebar: Case Report and Literature Review.

Blunt abdominal trauma is most frequent in the pediatric population. Duodenal lesions after abdominal trauma in children are infrequent and tend to be secondary to traffic accidents. It is up to five times more frequent in males, with an average age between 16 and 30 years. Bicycle accidents continue to lead to morbidity and mortality in children, representing between 5% and 14% of total blunt abdominal injuries. The diagnosis of duodenal injuries after trauma is difficult and requires a high index of clinical suspicion. We present the case of a 17-year-old patient seen in the emergency room after falling off his bicycle and presented a blunt trauma in the epigastric region. On physical examination, there was a swelling in the upper right abdominal quadrant and epigastrium with tenderness on deep palpation. He presented with hematemesis without hemodynamic repercussion. A contrast abdominal computed tomography was performed and he was diagnosed with third-part duodenal rupture. A resection of the perforated third-part duodenal rupture was performed, and the transit was reconstructed using a Roux-Y duodenojejunostomy. The postoperative period was uneventful and the patient was discharged after 16 days of stay. Duodenal injury is very rare, produced by high-energy trauma. They rarely present as single lesions as other visceral lesions are usually associated. The early diagnosis is important to reduce the morbidity and mortality.
