Diseases of the Peritoneum

Abstract

This chapter considers the wide range of nonneoplastic and neoplastic lesions that involve the peritoneum, and in some cases the retroperitoneal lymph nodes, of females. The first half of the chapter covers inflammatory lesions, tumor-like lesions (including mesothelial hyperplasia), mesothelial neoplasms, miscellaneous primary tumors, and metastatic tumors. The final half of the chapter is devoted to a large group of lesions that exhibit müllerian differentiation on microscopic examination and share a potential origin from the secondary müllerian system, the prototypical example of which is endometriosis.
