Malignant mixed Mullerian tumors are composed of a mixture of sarcoma and carcinoma. The carcinomatous element is usually glandular, whereas the sarcomatous element may resemble normal endometrial stroma (homologous or so- called carcinosarcoma). Here, we present a homologous type of malignant mixed Mullerian tumor of the uterus that pre- sented as a cervical mass. We describe a 55-year-old patient who had a cervical mass arising from the uterus. We performed total abdominal hysterectomy and bilateral salpingo-oophorectomy and surgical staging (including (peritoneal washings, suspicious areas or peritoneal surfaces sampled, infracolic omental sampling, pelvic and paraaortic lymph node sampling, and appendectomy). Carcinosarcomas of the uterine cervix are extremely rare, and when a post- menopausal woman with a cervical mass is admitted to the gynecology clinic, the physician should keep in mind that the mass might be a carcinosarcoma.

ABSTRACT Brenner tumors are rare ovarian tumors accounting for 2-3% of all ovarian neoplasms and about 2% of these tumors are borderline (proliferating) or malignant. These tumors are commonly seen in 4th-8th decades of life with a peak in late 40s and early 50s. Benign Brenner tumors are usually small, <2cm in diameter and often detected incidentally during surgery or on pathological examination. Authors report a case of a large, calcified benign Brenner tumor in a 55-year-old postmenopausal woman who presented with complaint of abdominal pain and mass in abdomen. Imaging revealed large complex solid cystic pelvic mass -peritoneal fibrosarcoma. She underwent laparotomy which revealed huge Brenner tumor weighing 9kg arising from left uterine cornual end extending up to epigastric region.

To learn more about how cancers start and spread, see What Is Cancer?1 There are many types of soft tissue tumors, and not all of them are cancerous. Many benign tumors are found in soft tissues.

  • 2. Cancer NOMENCLATURE HYSTOPATHOLOGY-STUDENTS
    Why it is important to give the right name to a CANCER disease understanding the pathology and/or histology of CANCER cancer helps you: • to make a correct diagnosis (fundamental Nomenclature - Histopathology step for a correct therapy) • to formulate a better research question (fundamental for studying the etiology, the molecular pathogenesis, and the progression of the disease) • to design novel targeted therapeutic strategies Cancer is not a single static state Neoplasia but a progression and mixture of phenotypic and genetic/epigenetic • Benign tumours : changes that proceed toward – Will remain localized – Cannot (by definition= DOES NOT) spread greater aggressive biological to distant sites behavior – Generally can be locally excised – Patient generally survives Mutation in Mutation in Increasing • Malignant tumours: gene A gene B,C, etc. chromosomal aneuploidy – Can invade and destroy adjacent structure – Can (and OFTEN DOES) spread to distant Normal Cell Increased Benign neoplasia Carcinoma proliferation sites – Cause death (if not treated ) Cancer Hystopathology Diagnosis Neoplasia • Biopsy • two basic components: • Fine-Needle aspiration (FNA) – Parechyma: made up of neoplastic cells • Exfoliative cytology (pap smear) – Stroma: made up of non -neoplastic, • Biochemical markers (PSA, CEA, Alpha- host -derived connective tissue and fetoprotein) blood vessels The parenchyma: The stroma: Determines the Carries the blood biological behavior of the supply tumor Provides support for From which the tumour the growth of the derives its name parenchyma 1. Principle of nomenclature NOMENCLATURE (1) Benign tumors Attaching the suffix “-oma” to the type of cell (glandular, muscular, stromal, etc) The most basic classification plus the organ: e.g., adenoma of thyroid. of human cancer is the More detail: organ or body location in The name of organ and derived tissue/ cell + morphologic character + oma which the cancer arises e.
