A

Staph a exotoxin

prolonged tampon use, prolonged intravaginal contraception use, postpartum or postabortion infection

Remove object if there is one
Treat the shock
Clinda, PCN-beta lactam; vanc if necessary

19
Q

Patient comes in with a painless ulcer on penis/vaginal wall. What is the likely cause? What is the near-future outcome?

A

Chancroid…can have large inguinal swelling

H. ducreyi

Ceftriaxone, erythromycin, or azithromycin

22
Q

A guy returns from a developing country with a painless ulcer on his penis. What causes lymphogranuloma venereum? What is the concern if this is lymphgranuloma venereum? How is it treated?

A

L1-L3 serotypes of C. trachomatis

Significant inguinal buboes…can ulcerate or cause elephantiasis

Tetracycline, erythromycin, or doxycycline

23
Q

Woman comes in with a painless ulcer with a beefy red bas and irregular borders. What is the likely diagnosis? What caused it? What would be seen on Giemsa stain?

A

Granuloma inguinale

Klebsiella granulomatis

Donovan bodies (red encapsulated intracellular bacteria)

24
Q

What is the most common cause of postmenopausal bleeding? What has to be ruled out? How?

A

Atrophic vaginitis is most common

Endometrial cancer must be ruled out with a biopsy (CA-125 may be elevated…but shitty marker until postmenopausal)

25
Q

A woman presents with abdominal pain and fullness. A palpable, tender mass is found on bimanual exam. What would suggest follicular cyst? What is the treatment?

A

Granolas cells with a 3cm cyst in first 2wks of cycle

Observation (may regress over menstrual period)
Ovarian cystectomy if mass does not regress or for increased suspicion of cancer

26
Q

A woman presents with abdominal pain and fullness. A palpable, tender mass is found on bimanual exam. What would suggest a corpus luteum cyst? What are some concerns? What is the treatment?

A

Theca cells; cystic or hemorrhagic…usually larger and firmer than follicular cyst, also more common later in cycle

Increased risk of torsion or rupture

Observation…cystectomy if stays or cancer…surgical hemostasis and cystectomy if hemorrhage

27
Q

A large growth is felt during both the bimanual exam and abdominal exam. What would be seen that would indicate mucinous or serous cystadenoma? How is it treated?

A

May resemble endometrial or tubal histology; psammoma bodies

Unilateral salpino-oophorectomy; TAH/BSO if postmenopausal

28
Q

What is an endometrioma? How is it treated?

A

Spread of endometriosis to the ovary

OCPs, GnRH agonists, progestins, danazol may lessen symptoms
Cystectomy or oophorectomy for recurrence

29
Q

A girl has precocious puberty and a cyst is found in her ovary. What kind of tumor is it?

A

Stromal cell tumor…granulosa theca cell tumor

30
Q

A girl has virilization and a cyst is found in her ovary. What kind of tumor is it?

A

Stromal cell tumor…Sertoli-Leydig cell tumor

31
Q

A young woman has multiple small, mildly painful masses in her breasts that vary in size during her cycle. What is this? How is it treated?

A

Fiborcystic changes

Caffeine and dietary fat reduction, OCPs, progesterone, or tamoxifen…in confirmed benign lesions

32
Q

A young woman (less than 30yo) has a solitary, solid, mobile mass with well-defined edges. What is likely going on? What should be ordered? How is it treated?

A

Fibroadenoma (most common benign breast tumor)…proliferative process in a single duct

FNA to confirm benign

Surgical excision or US-guided cryotherapy

33
Q

A woman has a palpable mass behind the areola and there is discharge from her nipple on stimulation. What is likely diagnosis? What would make it more concerning for malignancy? How is it treated?

A

Intraductal papilloma

Bloody discharge…get an excisional biopsy

Surgical excision

34
Q

What is the downfall to FNA of potential breast cancer?

A

Cannot differentiate between in situ and invasive carcinoma

35
Q

A mammogram showed a mass, so a biopsy was done that showed malignant cells in a duct without stream invasion. What is the diagnosis? What is a risk? How is it treated?

A

Ductal carcinoma in situ…often unifocal and may have calcifications

Higher risk of subsequent invasive cancer than LCIS

Lumpectomy and possible radiation

36
Q

A mammogram showed a mass, so a biopsy was done that showed malignant cells in lobules without stream invasion. What is the diagnosis? What is a risk? How is it treated?

A

Lobular carcinoma in situ…can be multifocal; no calcifications

Lower risk of invasion than DCIS, but increased risk of contralateral malignancy

Close observation and tamoxifen or raloxifene…bilateral mastectomy if woman doesn’t want to worry about it

37
Q

A woman comes in because one of her breasts looks like an orange. A biopsy shows malignant cells in ducts with stream invasion and microcalcifications. What is the diagnosis? What else is likely to be seen?

A

Infiltrating ductal carcinoma (most common…80% of cases)

Fibrotic response in surrounding breast tissue

38
Q

A woman comes in because her husband felt a firm mass in one of her breasts. A biopsy shows malignant cells in breast lobules with insidious infiltration. What is the diagnosis? What else distinguishes it from infiltrating ductal carcinoma?

A

Infiltrating lobular carcinoma

Less fibrous response
More frequently bilateral or multifocal
Slower metastasis
Greater association with hormone replacement therapy

39
Q

A woman comes in because of a soft, well-circumscribed mass that has been growing rapidly in one of her breasts. What is the likely diagnosis? What is the prognosis?

A

Medullary carcinoma

Better than ductal carcinoma

40
Q

An older woman comes in because of a gelatinous, well-circumscribed mass that has slowly grown. What is the likely diagnosis? What is the prognosis?

A

Tubular carcinoma

Better than ductal carcinoma

41
Q

A woman in her late-40’s is found to have a mass on mammogram. Biopsy shows well-formed tubular structures that invade the stroma. What is the diagnosis? What is the

A

Tubular carcinoma

Excellent

42
Q

A woman comes in because her breast is warm and painful. On exam, lymphadenopathy is found. What is the likely diagnosis? What is the prognosis? Treatment

A

Inflammatory carcinoma…subtype of ductal carcinoma characterized by rapid progression and angioinvasion

Poor prognosis

Mastectomy + hormones + chemo

43
Q

When are hormones or chemo used to treat breast cancer?

A

All node-positive cancers

Tumors >1cm or with aggressive histology
