Treatment and Management of Peritoneal Spread from Appendiceal Neoplasms
Surgical Oncology Clinics of North AmericaAppendiceal neoplasms are rare entities prone to direct peritoneal spread. As these neoplasms occur in few patients, research regarding their management is largely retrospective, limiting its utility. Classification of these neoplasms continues to evolve and is largely based on histopathology.

Discordant Histology of Primary Appendiceal Adenocarcinoid Neoplasms with Peritoneal Dissemination
Annals of Surgical Oncology, 2008Adenocarcinoid is a rare appendiceal tumor that shows histologically both epithelial and neuroendocrine components. We observed that some patients have peritoneal dissemination, which shows adenocarcinoma but lacks the neuroendocrine histology. The objective of the present study was to quantitate these discordant histopathological findings and examine ...

Perivascular epithelioid cell neoplasm of the bladder with peritoneal metastasis
Canadian Journal of UrologyPerivascular epithelioid cell tumors (PEComas) are a diverse group of mesenchymal neoplasms. While they have been described throughout the genitourinary system, PEComas are quite rare within the bladder. We present the case of a 37-year-old male who presented in clot retention and was found to have a bladder PEComa.
