Introduction: Small bowel angiosarcomas are exceedingly rare neoplasms with unspecific symptomatology which may lead to a delay in the diagnosis and consequently a worst prognosis. Case Report: A 73-year-old male patient presented with nausea, vomiting and abdominal pain. The blood test showed a mild anemia. Computed tomography (CT) scan revealed an ileal tumor. The patient was submitted to an exploratory laparotomy and segmental enterectomy. Pathology findings described an angiosarcoma. The patient had disease progression and died after two months. Conclusion: Angiosarcomas are high grade rapidly progressive neoplasms and have a very poor prognosis with a high mortality rate. The average life expectancy is 2-6 months after diagnosis.
Desmoid tumors represent a rare disease. The recommendations for treatment and approach of these neoplasms are sparse. There are no specific imaging or clinical features which turns the diagnosis difficult. A 53-year-old male patient presented with complaints of peri-umbilical abdominal pain associated with a palpable mass. CT scan revealed a heterogeneous mass with soft tissue density and well-defined contour with approximately 8.5×7×5.3 cm localized in the mesogastric region with apparent origin in the transverse colon. The purposed etiology was of GIST. Colonoscopy was normal. The patient was submitted to surgery which revealed a mass with bright and smooth surface that was in relation with the mid portion of the transverse colon, we performed a right extended hemicolectomy. The postoperative was uneventful. Pathology evaluation revealed a desmoid-type fibromatosis. The accurate etiology of desmoid tumors is still unknown. Desmoid tumors are rare with an annual incidence of 2-4 cases per million people. They typically are slow growing fibrous soft tissue tumors with a benign behavior, however show local aggressiveness with a high ability for recurrence, complete surgical resection with clear margins is crucial.
Introduction: We report a rare case of lowgrade appendiceal mucinous neoplasm (LAMN) within an incarcerated Amyand's hernia. Case Report: The patient was admitted for an elective surgery due to an asymptomatic rightsided inguinal hernia. The operative findings were suggestive of an appendiceal mucocele. Appendectomy and herniorrhaphy were performed. The histology report revealed a lowgrade appendiceal mucinous neoplasm. The patient had no clinical, biochemical or imaging signs of disease or hernia recurrence two years postoperatively. Conclusion: Surgical treatment involves appendectomy and hernia repair, which is performed without the implantation of synthetic mesh. The possibility of finding an incidental neoplasm should be considered during the surgery of an Amyand's hernia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
