We report a case of appendiceal mucinous cystadenoma that was successfully diagnosed preoperatively and treated by laparoscopic resection. We could find volcano sign on colonoscopy and cystic lesion without any nodules at the appendix on computed tomography (CT). Without any malignant factors in preoperative examinations, we performed laparoscopic appendectomy including the cecal wall. We could avoid performing excessive operation for cystadenoma with accurate preoperative diagnosis and intraoperative finding and pathological diagnosis during surgery. Appendiceal mucocele is a rare disease that is divided into 3 pathological types: hyperplasia, cystadenoma, and cystadenocarcinoma. The surgical approaches for it remain controversial and oversurgery is sometimes done for benign tumor, because preoperative diagnosis is difficult and rupturing an appendiceal tumor results in dissemination. Based on our study, volcano sign on colonoscopy and CT findings were important for the preoperative diagnosis of appendiceal mucocele. Furthermore, we think that laparoscopic resection will become a surgical option for the treatment of appendiceal mucocele.

Background: PRMC is a very rare benign tumor of the abdominal cavity that usually occurs in women, and PRMC demonstrate no specific findings on CT. There are many reports on the differential diagnosis and discussion of PRMC imaging, but there are few reports on the treatment of dedifferentiated PRMC using laparoscopic resection and postoperative follow-up.

Introdução: A mucocele do apêndice é um termo utilizado para descrever uma dilatação deste órgão, devido ao acúmulo de secreção mucoide, tornando o apêndice dilatado, de paredes finas e com uma massa cística no seu interior. Na maioria dos casos a mucocele é resultante de neoplasia que obstrui a luz apendicular. Relato de caso: Sexo feminino, 55 anos, branca. Procurou atendimento médico devido à dor abdominal de moderada intensidade há cinco anos. Refere que os sintomas iniciaram com dor em fossa ilíaca direita e região lombar há cinco anos, quando começou a tratar lombalgia. Nesse ano, buscou atendimento graças a piora da dor. O abdome estava globoso, flácido, doloroso a palpação superficial e profunda em fossa ilíaca direita com ruídos hidroaéreos presentes. Devido a sintomatologia foram solicitados um ultrassom de abdome total que evidenciou imagem cística tubuliforme em região anexial direita, de aspecto simples, de contornos regulares e conteúdo anecoico, medindo 13,3 cm x 5,2 cm x 4,3 cm, sem septos, calcificações ou fluxo ao Doppler e ressonância magnética da pelve que demonstrou formação cística alongada em região anexial, mergulhante na região anexial, apêndice cecal não individualizado. Foi realizada uma cirurgia exploradora que resultou em apendicectomia e o produto enviado para análise histopatológica que resultou em mucocele de apêndice, sem critérios histológicos de malignidade. As mucoceles de apêndice foram classificadas em 3 categorias: hiperplasia mucosa sem atipias, mucocele simples; cistadenoma mucinoso, com algum grau de atipia e cistadenocarcinomamucinoso, com invasão estromal ou implantes peritoniais. Conclusão: A sintomatologia é a dor abdominal, de intensidade e duração variáveis, podendo também ser observados a presença de massa palpável em fossa ilíaca direita e emagrecimento. Embora cerca de 25% dos casos sejam assintomáticos, alguns estudos demonstram a correlação entre sintomatologia exuberante e displasia. Aproximadamente 20% dos casos de mucocele de apêndice têm associação com o câncer colorretal, no entanto, outras neoplasias como os carcinomas de ovário, endométrio, mama, próstata, bexiga e rim também podem estar presentes.Descritores: Mucocele; Apêndice; Dor Abdominal.ReferênciasEnsuncho C, Osorio C, Marrugo Á, Herrera F.

Diagnosis of mid-cheek mass has always been a diagnostic dilemma for clinicians. The incidence of the accessory parotid gland (APG) has been well documented in the literature. However, a diverse spectrum of pathologies can arise from this accessory parotid tissue. Basal cell adenoma is a rare benign tumor that predominantly affects the parotid gland. Its occurrence in the accessory parotid gland has been documented in 9 cases till date. Surgical approaches for the management of such APG lesions have been in debate. This report documents a case of Basal Cell Adenoma arising in accessory parotid tissue in a 55-year-old woman who was treated by transoral excision. This paper also reviews previously documented cases of all APG lesions and attempts to elucidate the rationale for selecting an appropriate surgical approach.

Case summary A 6-month-old male domestic shorthair cat presenting with abdominal distension and an acute history of renal azotemia was diagnosed with bilateral perinephric pseudocysts and International Renal Interest Society (IRIS) grade 3 acute kidney injury. Ultrasound-guided drainage of the cysts was performed initially; bilateral subtotal resection of the perinephric pseudocysts was later performed using laparoscopy as a more long-term solution. There was no regrowth or reformation of the perinephric pseudocysts 1 year after the procedure, and the cat remained in IRIS stage 2 chronic kidney disease 1 year postoperatively. Relevance and novel information Compared with traditional surgical approaches, laparoscopic resection of perinephric pseudocysts provides a less invasive approach. Bilateral perinephric pseudocyst in a pediatric feline patient (and associated treatment) has not previously been documented in the literature.

Inferior mesenteric artery (IMA) aneurysms represent the minority of visceral aneurysm presentations. A 57-year-old female was admitted with a symptomatic IMA aneurysm secondary to atherosclerotic disease. She was treated with open excision which revealed a contained ruptured of a true aneurysm. This case highlights the challenges of an accurate preoperative diagnosis of IMA aneurysm and the correct position of the recent guidelines on visceral aneurysms issued by the Society of Vascular Surgery (SVS).

Mucocele is an uncommon pathology of the vermiform appendix estimated to be seen in 0.2-0.3%. The term mucocele means dilation of the appendix due to mucus, caused either by a benign or a malignant process. Herein, we report the case of a 77-year-old man with Calcinosis, Raynaud’s phenomenon, Esophageal dysfunction, Sclerodactyly and Telangiectasias syndrome, a limited form of Scleroderma, who had presented an abdominal cyclical pain and in which abdominopelvic computed tomography scan concluded to the diagnosis of appendiceal mucocele. Surgery and histopathology confirmed the diagnosis of mucinous cystadenoma. This association appendiceal mucocele and scleoderma has not been previously reported. The clinical and radiological features of this unusual complication are reviewed.
