Breast Cancer

Question Answer
FibroadenomaSmall, mobile, firm mass with sharp edges
Most common tumor in women < 35 y/o
↑ size/tenderness with ↑ estrogen (pregnancy/menstruation)
Benign - not a precursor to breast cancer
Intraductal papillomaSmall tumor that grows in lactiferous ducts beneath areola
Serous or bloody nipple discharge
Slight (1.5-2x) ↑ risk for carcinoma
Phyllodes tumorLarge bulky mass of connective tissue and cysts w "Leaf-like" projections
Most common in pts in their '50s
Some may become malignant
Malignant breast tumors (general info)Commonly post-menopausal, arising from terminal duct lobular unit in upper-outer quadrant of breast
Overexpression of estrogen/progesterone receptors or c-erbB2 (HER-2, an EGF receptor) is common → affects therapy and prognosis
Single most important prognostic factor in breast cancersaxillary lymph node involvement indicating metastasis
Ductal carcinoma in situ (DCIS)Fills ductal lumen - arises from ductal hyperplasia
Early malignancy without basement membrane penetration
Comedocarcinomanon-invasive ductal, caseous necrosis
Subtype of DCIS
Invasive ductalWorst and most invasive breast cancer
Firm, fibrous, "rock-hard" mass with sharp margins and small, glandular, duct-like cells
Classic "stellate" morphology
Most common (76% of all breast cancers)
Invasive lobularOrderly row of cells ("Indian file")
Bilateral with multiple lesions in the same location
MedullaryFleshy, cellular, lymphocytic infiltrate
Good prognosis
InflammatoryDermal lymphatic invasion by breast carcinoma
Peau d'orange (breast skin resembles orange peel)
Neoplastic cells block lymphatic drainage
50% survival at 5 years
Paget's diseaseEczematous patches on nipple
Paget cells = large cells in epidermis with clear halo
Suggests underlying DCIS
Also seen on vulva

Other breast conditions

Question Answer
MCC of "breast lumps" from 25-menopauseFibrocystic disease
Fibrocystic diseasePresentation: prementstrual breast pain and multiple lesions, often bilateral
Usually does not indicate ↑ risk of carcinoma
Fibrosis - fibrocystic diseasehyperplasia of breast stroma
Cystic fibrocystic diseasefluid filled, blue dome
Ductal dilation
Sclerosing adenosis - fibrocystic disease↑ acini and intralobular fibrosis
Assoc w calcifications
Often confused with cancer
Epithelial hyperplasia - fibrocystic disease↑ in number of epithelial cell layers in terminal duct lobule
↑ risk of carcinoma with atypical cells
Women > 30 y/o
Acute mastitisBreast abscess
During breast-feeding
↑ risk of bacterial infxn through cracks in nipple
Staph A. is the most common pathogen
Fat necrosisA benign, usually painless lump
forms as a result of injury to breast tissue
Up to 50% of patients may not report trauma
GynecomastiaHyperestrogenism in males → boobies
Non-drug causes of gynecomastiaCirrhosis, testicular tumor, puberty, old age, Klinefelter's syndrome
Drug causes of gynecomastia"Some Drugs Create Awkward Knockers"
Others: estrogen, heroin, marijuana, psychoactive drugs

Male Path

Question Answer
Prostatitisdysuria, frequency, urgency, low back pain
Cause of acute prostatitisBacterial (E. coli)
Cause of chronic prostatitsBacterial or abacterial (most common)
BPHHyperplasia (not hypertrophy) of prostate gland
Nodular enlargement of later & middle lobes (periurethral)
Not a premalignant lesion
Treatment of BPHα1- antagonists (terazosin, tamsulosin) → relacation of smooth muscle
Prostatic adenocarcinomaMost arise from posterior lobe (peripheral zone)
Dx vs ↑ PSA and subsequent needle-core biopsy
Useful tumor markers: Prostatic acid phosphatase (PAP), PSA - ↑ total PSA w ↓ fraction of free PSA
Lower back pain indicates osteoblastic mets (↑ serum alk phos and ↑ PSA)
Cryptorchidismundescended testis (one or both)
Impaired spermatogenesis due to ↑ temp
↓ inhibin, ↑ FSH, ↑ LH, ↓ testosterone (bilateral) or normal testosterone in unilateral
Assoc w ↑ risk of germ cell tumors
Prematurity increases the risk of cryptorchidism
VaricoceleDilated veins in pampiniform plexus as a result of ↑ venous pressure (MC on left side)
↑ temp → can cause infertility
MCC of scrotal enlargement in adult males
"bag of worms"
Tx: varicocelectomy, embolization by interventional radiology
Testicular mass that doesn't transilluminatecancer
Painless, homogenous testicular enlargement
MC testicular tumor
Males 15-35
Large cells in lobules with water cytoplasm and a "fried egg" appearance
↑ placental alkaline phosphatase (PLAP)
radiosensitive, late mets so excellent prognosis
Yolk sac (endodermal sinus) tumorYellow, mucinous.
Analog to ovarian yolk sac tumor
Shiller-Duval bodies resemble primitive glomeruli (↑ AFP)
↑ hCG
Disordered syncytiotrophoblastic and cytotrophoblastic elements
Hematogenous mets to lungs
Gynecomastia as hCG is an analog of LH
TeratomaOften malignant (unlike in females)
Benign in children
↑ hCG and/or AFP in 50% of cases
Embryonal carcinomaMalignant
Worse prognosis
Glandular/papillary morphology
"pure" embryonal carcinoma is rare - most commonly mixed with other tumor types
Assoc w ↑ hCG and normal AFP levels when pure (↑ AFP when mixed)
Testicular germ cell tumors (general)~95% of all testicular tumors
Most often malignant
Leydic cell testicular tumorReinke crystals
Adnrogen producing → gynecomastia in men, precocious puberty in boys
Golden brown color
Sertoli cell testicular tumorAndroblastoma from sex cord stroma
Testicular lymphomaMC testicular cancer in older men
Not a primary cancer - arises from lymphoma mets to testes
Hydrocele↑ fluid 2° to incomplete fusion of processus vaginalis
Spermatoceledilated epididymal duct (tunica vaginalis lesion)
SCC of the penisMore common in asia, africa, and south america
Assoc w HPV & lack of circumcision
Peyronie's diseaseBent penis d/t acquired fibrous tissue formation
PriapismPainful sustained erection not assoc w sexual stimulation or desire
Assoc w trauma, sickle cell disease, medications (anticoagulants, PDE5 inhibitors, antidepressants, α-blockers, cocaine)
