Pseudomyxoma peritonei (PMP) is a rare disease that usually originates from mucinous neoplasms of the appendix and, less commonly, from extra-appendiceal tumors, but it may also be caused by synchronous primary mucinous tumors of the ovary and appendix. The current study discusses the case of a 73-year-old female who presented with progressively worsening indigestion and abdominal distension. M...

CONTEXT Diagnosis and treatment of cystic neoplasms of the pancreas increased significantly in the last decades. There are only a few Brazilian publications on these tumors. The majority of them are limited to reports of one or few cases. OBJECTIVE To present our experience with 27 patients with cystic neoplasms of the pancreas. METHODS Demographic data, clinical manifestations, diagnostic ...

We report a case of giant mucinous cystic neoplasm (MCN) of the pancreas that was successfully treated with laparoscopic surgery. A 29-year-old woman was admitted to our hospital for evaluation of an abdominal tumor that had been detected during a routine medical examination. The tumor was diagnosed as an MCN of the pancreas. We performed laparoscopic distal pancreatectomy and splenectomy. The ...

A 60-year-old Caucasian male underwent a total pancreatectomy for a mixed type pancreatic intraductal papillary mucinous neoplasm (IPMN) arising in the main and secondary pancreatic ducts. During surgery, a subserosal polypoid mass was noted at the greater curvature of the gastric antrum and was enucleated. This mass was proven to be heterotopic pancreatic tissue with cystic neoplasia of the IP...

We read with interest the article ‘Pancreatic Mucinous Cystic Neoplasm Size Using CT Volumetry, Spherical and ellipsoid formulas: Validation Study’ by Chalian et al. [1] published in the January 2014 edition of Journal of the Pancreas .JOP (online). We commend the authors for their valuable contributions towards establishing the accuracy and reproducibility of CT volumetry for pancreatic cysts....

Drs. Levy and Wiersema have provided an authoritative review of the role of endoscopic ultrasonography in the diagnosis and staging of pancreatic cancer. As outlined in their article, endoscopic ultrasound has emerged as an important tool in the diagnostic evaluation of many patients with suspected pancreatic neoplasms. We concur that endoscopic ultrasound is part of the standard preoperative e...

Here we report a case of benign intraductal papillary-mucinous neoplasm (IPMN) of the pancreas containing two major subtypes. A 73-year-old man underwent pancreatoduodenectomy for a cystic mass, 5.0 cm in diameter. Histopathologic examinations revealed that IPMN was composed of gastric-type adenoma and intestinal-type borderline lesion. Marked intraluminal nodular growth was observed in the cen...

Primary mucinous carcinoma of the skin is a rare sweat-gland neoplasm with a high recurrence rate. We report a new case of a primary recurrent mucinous carcinoma of the face in a 59-year-old man. Histopathologic examination of the neoplasm showed epithelial islands floating in mucoid material compartmentalized by fibrous septa. Cytokeratin 7, protein S100, estrogen and progesterone receptors we...

uterine sarcoma is a rare tumor of mesodermal origin, accounting for 2-6% of uterine malignancies. leiomyosarcoma (lms) has been reported in only 1% of all uterine malignancies and is regarded as the most common primary uterine sarcoma. herein, we present a case of lms with unusual macroscopic features. the patient was a 61-year-old woman with lms, which consisted of a large cystic mass (88×136...
