36
infertility is common in women with endometriosis and is thought to be due to it's also common in PID

38
Adenomyosis generally refers to the presence of

micro-abscesses or neutrophils within the endometrial glands
41
chronic endometritis is characterized by the presence of what?
plasma cells (nuclei that are off to the side of the cell- eccentric)
42
what is the most characteristic and common component of PID?
infxn of the oviducts
43
although an _______ is the most common cause of PID, many other routes of infection are possible, including _________
STI lymphatic or hematogenous spread, postpartum or post-abortion infections and infection related to the presence of an intrauterine device (IUD).
44
atypical hyperplasia often presents with atypical bleeding due to
an estrogen dominant environment
45
endometrial cancer is the most common gynecological cancer. what type endometrial cancer is the most common?
adenocarcinoma
46
increased risk for developing endometrial cancer has been linked to:
nulliparity obesity (peripheral conversion of estrogen) DM (insulin has a GF like effect) HTN
47
a far less common type of endometrial cancer than adenocarcinoma is
serous carcinoma of the ovary (papillary serious carcinoma)
48
microscopically papillary serous carcinoma is notable for
accumulation of nuclear p53 protein (aberrant p53)
49
leimomyomas, aka what are they
fibroids | benign smooth muscle tumors of the uterus
50
Leiomyomas usually present as
discrete, well-circumscribed tumors that are often round, firm and when sectioned appear gray-white in color.
51
These cells have a characteristic
whorled pattern of smooth muscle
52
leiomyoma sarcoma and sarcomas in general have a characteristic cell shape

80
microscopically embryonal carcinoma appears
Sheets of cells are trying to form primitive tubules
81
a teratoma is an
encapsulated tumor
82
does benign prostatic hyperplasia (BPH) increase the risk of cancer?
Answer? NO! Although it does elevate PSA levels
83
microscopically benign prostatic hyperplasia appears
1) well-differentiated glands with tall columnar epithelial lining cells (normally there is one row of columnar cells and an outer layer of cuboidal to myoepithelial cells)
