Review Ovarian Histology
Norm No. 4 Ovary
[DigitalScope]
Ovary tissue consists of stoma which is composed of elongated stromal cells. Within the stoma are oocytes in various stages of development. Most of the oocytes have not been stimulated to mature. These resting oocytes have very large nuclei with prominent nucleoli. There are corpora albicantia in a bland stroma. The Corpus Luteum of Pregnancy is composed of granulosa cells with abundant foamy cytoplasm. The granulosa cells are arranged in complex folds.
|
|
The ovary is enlarged and has a heterogeneous appearance with areas of fleshy, white tissue. Focally, there is a cyst. Notably, there is no grumous, sebaceous material present.
|
There are a variety of mature tissues, including choroid plexus (the papillary structures near the center of the tissue), and squamous epithelium (most of the top edge of the tissue). The immature component is seen best in the lower left quadrant of the slide, where there are several highly cellular “blue” areas at low power. At higher power, there are large numbers of primitive small cells with hyperchromatic nuclei, some of which are arranged in rounded “rosettes” around a central lumen-like space These are neuroblasts, and are by far the most common immature component seen in immature teratomas.

Review Mammary Gland Histology
Norm No. 19 Mammary Gland
[DigitalScope]
The female breast is a secretory organ that produces milk during lactation. Breast tissue that is not stimulated to lactate consists of resting apocrine cells arranged in nests and small ductules which are lined by cuboidal epithelium. The secretory units are separated from one another by loose connective tissue.
|
|
There is inflammation and dimpling of the areola. The cut surface of the resected breast tissue reveals a 3 x 3 x 2 cm firm mass with stellate borders. The center of the mass is firm, scirrhous and white because of the desmoplasia. There are areas of yellowish necrosis in the portions of neoplasm infiltrating into the surrounding breast. Such tumors appear very firm and non-mobile on physical exam.
|
The virtual image was derived from a breast biopsy on another patient and shows both intraductal carcinoma with a comedo pattern of necrosis and invasive infiltrating ductal carcinoma. Ductal carcinomas range from well-differentiated tumors characterized by good duct formation to poorly-differentiated tumors. This one is composed of infiltrating glands and sheets of pleomorphic cells which infiltrate into the adjacent breast tissue. This infiltrating ductal carcinoma of breast at low magnification appears to radiate from a central area of desmoplasia. This collagenous component gives the neoplasm a hard "scirrhous" consistency that is palpable on physical examination or breast self-examination. Such an invasive carcinoma may be fixed to underlying chest wall, making it non-mobile. Also note the nerve which is invaded by tumor. It would also be important for treatment and prognosis to determine if the tumor cells were estrogen and progesterone receptor positive.

Review Uterine Histology
Norm No. 21 Uterus
[DigitalScope]
The uterus is a reproductive organ, capable of enormous growth during pregnancy. It is composed of an inner endometrium which supports the placenta during pregnancy. The glandular endometrium undergoes monthly cycles in response to endocrine influence. It undergoes proliferation and then a secretory phase when it is capable of supporting a fertilized ovum. It is subsequently shed during menstruation. The endometrial here is proliferative. If you look carefully you can see mitotic figures in the endometrial glands. Note the regular spacing and orderly array of the endometrial glands. Beneath the endometrium is the myometrium which is composed of smooth muscle cells.
|
|
There are fragments of tissue that show papillary architecture. The neoplastic cells show marked cytologic atypia, a high nuclear-to-cytoplasm ratio and brisk mitotic activity. There are scattered foci of necrotic cells. Psammoma bodies are not present in this section. These tumors may show glandular or solid growth patterns, in addition to papillations.

Review Placental Histology
Slide 253 placenta, 1st trimester DigitalScope
Slide 255 placenta, term DigitalScope
With the implantation of a zygote into the uterus, a number of changes take place in the endometrium. Cells from the embryonic trophoblast invade the uterine mucosa, secretions from these cells coalesce to form lacunae in the endometrium, which is now termed the decidua. These spaces also contain maternal blood. The trophoblast rapidly invades the decidua forming primary villi, that contain only trophoblast (outer syncytiotrophoblast and inner cytotrophoblast) cells. Mesenchyme and blood vessels form the core of the secondary villi. During the second half of pregnancy the cytotrophoblast cells disappear and the capillary basal lamina fuses with that of the syncytiotrophoblast to improve exchange.
Begin with slide 253 DigitalScope , which is early placenta. The entire field is filled with villi cut predominantly in cross section. Mesenchymal tissue and fetal blood vessels (filled with fetal RBCs which, in the early stages of fetal hematopoiesis, still have nuclei) make up the core of each villus which is covered by a trophectoderm shell of inner cytotrophoblast and outer syncytiotrophoblast cells. The syncytiotrophoblast cells are more eosinophilic and have smaller nuclei. As the name implies, these cells result from the fusion of many cells and thus have many nuclei per cell and no discernable lateral boundaries. In contrast, cytotrophoblast cells are clearly demarcated, have a single, large nucleus and basophilic cytoplasm. Notice that there is almost a complete ring of cytotrophoblast cells covering each villus in early placenta --these cells are thought to function as stem cells for the formation of the syncytiotrophoblast, which is why they may disappear later in pregnancy.
Study slide 255 DigitalScope, which is a late placenta. Although you will be able to see an occasional cytotrophoblast cell, you will not be able to see forming villi in this late placenta. Examine the trophectoderm shell, which now consists of multinucleate syncytiotrophoblast cells located on the outer surface of the villi as well as an occasional residual underlying cytotrophoblast cell. The nuclei of the syncytiotrophoblast cells often form aggregates of so-called "syncytial knots" that may look like specks of dirt when viewed at lower magnification. Syncytiotrophoblast cells that are bathed in maternal blood have apical surfaces specialized for absorption (microvilli), pinocytosis, and exocytosis and an appearance typical of secretory cells. Also examine the numerous macrophage-like (Hofbauer) cells that can be found within the connective tissue of the placental villi. These cells are characteristically large, with elliptical, eccentric nuclei and extensively vacuolated cytoplasm.
Many late or term placenta exhibit an amorphous eosinophilic fibrinoid substance, deposited in the intervillus space as shown in this older placenta. This material clings to the villus surface and may bind several villi together. The amount of fibrinoid deposition in combination with the appearance of the connective tissue in the villi can be used to stage the placenta. Although some degree of fibrinoid deposition is normal, excessive deposition can impede oxygen exchange and can cause placental failure.
|
The placenta is composed of masses of grape-like clusters of hydropic villi. Fetal tissue and normal placental tissue are not present.
|
The enlarged chorionic villi are poorly vascularized and have edematous stroma with scattered “cisterns”. There is diffuse proliferation of both cytotrophoblast and syncytiotrophoblast in a circumerferential pattern. Normal villi are not present. On the left side of the slide is a portion of decidualized endometrium.

Review Oviduct Histology
Norm No. 20 Uterine (fallopian) tube (aka oviduct)
[DigitalScope]
The fallopian tube is lined by ciliated columnar epithelium that aid in transport of the ovum to the uterus. The epithelium is arranged in fronds that project into the lumen. The wall consists of smooth muscle and connective tissue.
|
|
The uterine tubes were markedly distended and thickened with adhesions between the fimbriated end and the ovaries. On sectioning, pus exuded from the lumen.
|
The villi are plump and edematous, with marked dilation and congestion of capillaries. The mucosa is heavily infiltrated by polymorphonuclear leukocytes, which have broken through foci of necrotic mucosa, producing the purulent exudate. Besides this acute phase, there are chronic features evidenced by plasma cell, lymphocytic and macrophage infiltration and fibroblastic proliferation. The muscular layers are edematous and infiltrated by acute and chronic inflammatory cells. This probably represents gonorrheal infection, the mucosa being predominantly involved, in contrast to other pyogenic infections which more frequently involve the outer layers and relatively spare the mucosa.
