Q

Klinefelter Syndrome

A

47 XXY. Testicular atrophy, eunuchoidal appearance, tall, slender gynecomastia. Presence of barr body in nucleus (electron dense area in nucleus). Common cause of hypogonadism and infertility.

Causes dysgenesis of seminiferous tubules. Decreased inhibin and increased FSH. Also abnormal leydig cell function. Decreased testosterone, increased LH, increased estrogen.

Q

Turner Syndrome

A

45 XO. Short stature, webbed neck, shield chest. Streak ovary.

Preductal coarctation (Xoarctation of aorta). Horseshoe kidney.

Most common cause of primary amenorrhea. No barr body.

Decreased estrogen leads to increased FSH and LH. Can result for mitotic or meiotic error.

Non-neoplastic endometrial glands/stroma outside of the endometrium. Most commonly in ovary, pelvis, peritoneum. Characterized by cyclic pelvis pain.
27
Adenomyosis
Where the endometrium dives down into the myometrial layer. Treat with hysterectomy

29
Endometrial carcinoma
Most common gynecologic malignancy usually at 55-65. can present with vaginal bleeding and is typically preceeded by endometrial hyperlasia. Risk factors usually due to increased estrogen without progestins
30
Endometrial carcinoma
Most common gynecologic malignancy usually at 55-65. can present with vaginal bleeding and is typically preceeded by endometrial hyperlasia. Risk factors usually due to increased estrogen without progestins
31

Incidence of gynecologic tumors | mortality of gynecologic tumors
Endometrial>Ovarian>cervical | Ovarian>cervical>endometrial
33
Most common cause of anovulation?
PCOS, cushing syndrome
34
PCOS (stein leventhal syndrome
Syndrome where there is increased activity of theca cells producing androgens, but aren't converted by granulosa cells to estrogen. Signs of androgen excess (hirsuitism, amenorrhea, acne). Associated with obesity and insulin resistance. LH/FSH is 3:1. Ultrasound shows many follicles in ovary due to low FSH
35
How to treat PCOS
Oral contraceptives, Metformin, clomiphene (to block negative feedback of estrogen), cyclic progesterones
36

Caused by rupture into corpus luteum.
38
Follicular cyst
Distension of unruptured graffian follicle. Most common ovarian mass. Associated with increased estrogen.

Caused by rupture into corpus luteum.
40

Chocolate cyst
41

Review them
61
Prostatitis
Dysuria, increased frequency of urination and urgency. Low back pain. Mostly from e.coli. Abacterial most common if chronic
62
BPH
Driven by DHT. Common in men >50. In perirurethral zone. Presses urethra. Not premalignant but can increase PSA. Can also cause hydronephrosis.
63
How to treat BPH
``` Alpha antagonists (terazosin, tamulosin) -- relax smooth muscle. Finasteride (5Areductase inhibitor) ```
64
Prostatic adenocarcinoma
Men>50. Posterior lobe of peripheral zone. Increased PSA then needdle biopsy. PAP and PSA are important. Causes osteoblastic bone lesions.
65
How to treat prostatic adenocarcinoma
Prostatectomy, leuprolide (GNRH agonist continuously), or flutamide (androgen receptor inhibitor).
66
How to treat prostatic adenocarcinoma
Prostatectomy, leuprolide (GNRH agonist continuously), or flutamide (androgen receptor inhibitor).
67
Cryptorchidism
Undescended testicle causes impaired spermatogenesis (since sertoli cells are affected by temp) testosterone normal. Increased risk of seminomas. Decreased inhibin, increased FSH and LH.
68
Varicocele
Dilated veins in pampiniform plexus due to increased venous pressure.
69
Varicocele
Dilated veins in pampiniform plexus due to increased venous pressure. Left side more common. Bag of worms. increased temp.
70
Seminoma
Painless homogenous testicular enlargement. Most common testicular tumor occurs during 20s. Fried egg appearance. Increased placental ALP. Late mets with good prognosis
71
Yolk Sac tumor
yellow mucinous, aggressive. Like ovarian yolk sac tumor Schiller-duval bodies look like primative glomeruli. Common in boys
72
Choriocarcinoma

73
Teratoma
Malignant in males. AFP up in most cases.
74
Embyonal carcinoma
Early mets, primative cells that grow rapidly. usually mixed. increased HCG and normal afp when pure. Painful. Worse prognosis
75
Leydig cell tumor
Contain Reinke crystals. Produce antrogens.
76
Testicular lymphoma
Usually in older men from Diffuse large b cell lymphoma.
77
Squamous cell carcinoma of the penis
Common is asia africa south amercia. precursos in situ lesions.Bowen disease (leukoplakia) erythroplasia of Queyrat (cancer of glands) . Associated with HPV lack of circumcision.
