9. Invasive Cervical carcinoma

10. Prof DR Suzan Kato10 Microscopically, there are three different types of invasive carcinoma: (1)large cell, nonkeratinizing squamous carcinoma—the most common type, with the best prognosis (2)keratinizing squamous carcinoma—next most common, with an intermediate prognosis; (3) small cell carcinoma—rare, with a poor prognosis. (4)Endocervical adenocarcinoma accounts for 10–15% of cervical cancers. It arises in the endocervical glands

12. Tuberculous endometritis

13. They vary in size from 0.5 to 3 cm and are covered by endometrial epithelium. Microscopically, composed of endometrial glands and a fibrovascular stroma. Clinically, endometrial polyps may be asymptomatic or may cause excessive uterine bleeding. Endometrial polyps

14. Uterine polyp A -single polyp extends into the endometrial cavity. The necrotic tip is responsible for clinical bleeding. B. On microscopic section, a polyp exhibits dilated endometrial glands embedded in a markedly fibrous stroma.

16. Adenomyosis The uterus may be enlarged. The myometrium discloses small, soft, cysticareas Adenomyosis The uterus may be enlarged. The myometrium discloses small, soft, cystic areas

17. Adenomyosis endometrial glands and stroma in the myometrium.

18. End hyperplasia The endometrial cavity is opened to reveal lush fronds of hyperplastic endometrium. The endometrial cavity is opened to reveal lush fronds of hyperplastic endometrium.

19. Endometrial hyperplasia SimpleComplexAtypical A, Anovulatory or "disordered" endometrium with dilatation of glands. B, Complex hyperplasia displaying a nest of closely packed glands. C, Atypical endometrial hyperplasia with crowding of glands, unfolding of tall columnar cells, and some loss of polarity.

20. Leiomyoma Multiple leiomyomas of the uterus. Several large, almost pedunculated tumors protrude from the dome of the fundus. The lower uterine segment and cervix are below Multiple leiomyomas of the uterus. Several large, almost pedunculated tumors protrude from the dome of the fundus. The lower uterine segment and cervix are below

21. Leiomyoma: Microscopically leiomyomas exhibit interlacing fascicles of uniform spindle cells, in which nuclei are elongated and have blunt ends. The cytoplasm is abundant, eosinophilic, and fibrillar. leiomyomas are distinguished by their circumscription, nodularity, and denser cellularity

22. Leiomyosarcoma: bulky masses infiltrating the uterine wall, as polypoid lesions projecting into the uterine cavity, soft, hemorrhagic, and necrotic soft.has irregular borders due to invasion into neighboring myometrium

23. leiomyosarcoma Criteria of malignancy include necrosis, cytologic atypia, and mitotic activity. Criteria of malignancy include necrosis, cytologic atypia, and mitotic activity.

27. Endometrial Carcinoma 27Prof DR Suzan Kato

28. ENDOMETRIOID ADENOCARCINOMA is the most common histologic variant (60%). The FIGO system divides this tumor into three grades. Grade 1: Well differentiated; composed almost exclusively of neoplastic glands, with only minimal (<5%) solid areas. Grade 2: Moderately differentiated; formed partly of glandular elements and partly (<50%) of solid tumor. Grade 3: Poorly differentiated; shows large (>50%) areas of solid tumor

29. Endometrial carcinoma: A, Endometrioid type, infiltrating myometrium and displaying cribriform architecture. B, Higher magnification reveals loss of polarity and nuclear atypia. 29Prof DR Suzan Kato

33. Microscopically, the cysts are composed of dilated chorionic villi, the interior being filled with an avascular, loose myxoid stroma. the cysts are composed of dilated chorionic villi, the interior being filled with an avascular, loose myxoid stroma.

36. Morphology of Choriocarcinomas Grossly the tumor usually appears as very hemorrhagic, necrotic friable mass within the uterus. Sometimes the necrosis is so complete that anatomic diagnosis is difficult. Grossly the tumor usually appears as very hemorrhagic, necrotic friable mass within the uterus.
