Full Definition
Carcinomatosis describes the widespread distribution of malignant cells throughout a body cavity, most commonly referring to peritoneal carcinomatosis in gynecologic cancers. The condition involves multiple tumor implants scattered across serosal surfaces, often appearing as a 'studding' pattern on imaging. In gynecologic oncology, peritoneal carcinomatosis is frequently seen in advanced ovarian, fallopian tube, and primary peritoneal cancers.
