Cistadenoma mucinoso del apéndice cecal como causa de gangrena intestinal / Appendiceal mucocele causing large bowel gangrene

Introduction: Appendiceal mucocele are lesions located in the cecum, which are found in 0.2 to 0.3 percent of appendectomies and correspond to 8-10 percent of all appendiceal tumors. Clinical case: We report a 83 years old female consulting for abdominal pain lasting 24 hours. On physical examination, signs of peritoneal irritation were found. The patient was operated, finding an appendiceal tumor that was coiled up in the mesentery with large bowel gangrene. An intestinal resection, terminal ileostomy, appendectomy and surgical lavage were performed. The pathological study of the surgical piece reported a mucinous cystadenoma.

Introducción: Los tumores del Apéndice Cecal corresponden al 0,5 por ciento de las neoplasias gastrointestinales y se encuentran entre el 0,8 por ciento y el 1 por ciento de las apendicectomías. El término Mucocele Apendicular (AM), se refiere a un grupo de lesiones localizados a nivel del ciego cuyo rango de incidencia está entre el 0,2 por ciento y el 0,3 por ciento de todas las apendicectomías, y entre el 8-10 por ciento de todos los tumores apendiculares. Las presentaciones clínicas más frecuentes son: cuadro clínico de apendicitis aguda, como hallazgo incidental como en el caso de esta paciente, o como masa abdominal en fosa ilíaca derecha. Caso clínico: Se presenta un caso de Cistade-noma Mucinoso Apendicular (CAM) encontrado como hallazgo incidental en un abdomen agudo quirúrgico con la particularidad de presentarse con una necrosis intestinal.

Repeatedly Recurrent Colon Cancer Involving the Appendiceal Orifice after Endoscopic Piecemeal Mucosal Resection: A Case Report / 대한소화기학회지

Local recurrence after endoscopic piecemeal mucosal resection (EPMR) for colorectal tumors is a crucial issue. However, such recurrence is usually detected within one year and cured with additional endoscopic treatment, which makes EPMR acceptable. Herein, we report a rare case of repeatedly recurrent colon cancer involving the appendiceal orifice after EPMR, which was not cured with additional endoscopic treatments. A 67-year-old man was referred to us for endoscopic treatment of a 25 mm cecal tumor spreading to the appendiceal orifice in May 2002. The tumor was resected with EPMR, showing well differentiated intramucosal adenocarcinoma with a positive lateral cut margin of tubular adenoma. Endoscopic surveillance was conducted and the first local recurrence was detected in August 2006. Although we resected it endoscopically, the second local recurrence was found in September 2007 and we removed it with endoscopic resection again. However, the third local recurrence was detected in March 2008. Although endoscopic resection was performed also for the third recurrence, curative resection was not achieved. In February 2009, laparoscopic assisted colectomy was performed and histopathological examination showed well differentiated adenocarcinoma with deep submucosal invasion. This case is important in considering indication for endoscopic resection in colorectal tumors involving the appendiceal orifice.

[Recurrent obstructions after resonance stent placement in the treatment of ureteral compression from malignant disease]

Background: The Resonance ureteral stent is a newly developed all-metallic double-pigtail ureteral stent allowing a palliative diversion on a patient with malignant ureteral obstruction

Aim: To define selection criteria of good candidates for Resonance stent

Case: A 62-year-old woman was admitted to the emergency department with complaining of severe right flank pain and anuria. Twelve days earlier, we had placed retrogradely a ureteral metallic Resonance stent [Resonance: Cook Ireland Ltd, Limerick, Ireland] for the treatment of a ureteral compression from pelvic recurrence of an appendical colloid mucosal carcinoma in a solitary functionning right kidney. A percutaneous nephrostomy catheter was placed, and an antegrade nephrostogram demonstrated complete distal ureter obstruction. The patency of the ureteral stent was restored spontaneously and then, nephrostomy catheter was removed. Two weeks later, she presented with obstructed ureteral stent. Percutaneous nephrostomy was performed and Resonance stent was removed definitively. Ureteroscopy with biopsy confirmed the tumor extension into the ureteral lumen

Conclusion: The risk of subsequent obstruction after Resonance metallic ureteral stent placement is real. Patients with intra-ureteral tumour extension are presumably not good candidates for Resonance stent management

Association of ulcerative colitis with pulmonary sarcoidosis, subcutaneous lipomatosis and appendiceal adenocarcinoma.

We report a 52-year-old man with left-sided ulcerative colitis for 5 years and pulmonary sarcoidosis diagnosed 3 years back. He presented with subcutaneous lipomatosis and a right iliac fossa mass, which was diagnosed histologically as appendiceal adenocarcinoma. He was treated with right hemicolectomy, followed by chemotherapy.

Spontaneous appendicocutaneous fistula.

Spontaneous appendicocutaneous fistula is a rare complication of appendicitis. We report a case of appendicular carcinoid who presented with appendicocutaneous fistula.

Pseudomyxoma peritonei. A report of three cases.

Pseudomyxoma peritonei is an infrequently encountered clinical entity which presents mainly with abdominal distension. We present here our experience with three such cases and emphasize on the aggressive combined operative and chemotherapeutic approach in this disease.

Mucocele e tumor carcinóide do apêndice vermiforme / Mucocele and carcinoid tumor of vermiform appendix

Os autores relatam um caso raro de associaçäo de mucocele e tumor carcinóide localizados no apêndice vermiforme. O paciente era assintomático e num exame médico de rotina foi dagnósticado tumor no quadrante inferior diereito do abdome. A tomografia computadorizada demonstrou a presença de massa cística no hipogastrio e fossa ilíaca direta, compatível com cisto de úraco. Durante a cirurgia evidenciou-se mucocele gigante do apêndice vermiforme e o exame histopatológico da peça cirúrgica revelou também a presença de tumor carcinóide

Tumor carcinoide y apendicitis aguda: informe de 4 casos / Carcinoid tumor and acute appendicitis: report of 4 cases

Se realiza un estudio de los tumores carcinoides del apéndice cecal. Se describen los caracteres macroscópicos y microscópicos de esta entidad nosológica y se revisan los criterios de tratamiento. El trabajo recoge un estudio de las apendicectomías realizadas entre los años 1977-1981. Se detectan pacientes con apendicitis aguda y tumor carcinoide. A los mismos se les hizo un estudio evolutivo posoperatorio
