Male GU Flashcards
Congenital Hypospadias
urethra opens on dorsum of the penis** notice before circumcision (need foreskin to repair)due to abnormal closure of the median raphe- epispadias = towards eye- hypospadias = down
Balantis
infection of the glansuncircumcised
Hydrocele
fluid in testestransilluminatein babies the fluid is peritoneal bc inguinal ring often hasn’t closed
Elephantitis
due to filiariasis (transmitted by mosquitos) which blocks lymphatic drainage
Varicocele
more common on LEFT (drainage of L testicular vein into the L renal vein)bag of worms
Causes of prostatitis1) acute bacteria2) chronic bacteria3) chronic abacterial4) granulomatous
1) gram (-) bacteria, assoc w/ UTI or surgery2) gm (-), hx of prior UTI3) sexually transmitted4) TB, fungal, BCG
Prostate Ca
Firm tan-yellow nodules; peripheral lobesProminent nucleoli, lack enveloping basal cellsLove invading the nervesAdenocarcinomas!!There is a small cell carcinoma; poor prognosis, lung met until proven otherwiseUsually only palpable on DRE w/ stage 3 or 4
Malakoplakia
Mimics testicular neoplasm; area of dense fibrosis; inflammatory infiltrate w/ plasma cells/lymphocytes and macrophagesSome macrophages contain bluish spherules; these macrophages are called Von Hansemann cells and the bodies are called Michaelis-Gutman bodiesRelated to infection, but host reaction abnormal causing a granulomatous-like, mass-forming inflammation
Causes of Atrophic Testicle
chronic alcoholismhypopituitarismatherosclerosischemoradiationmumps**cryptorchidism
Testicular Tumors
White males 15-35Germ cell tumors = malignant (90% of tumors are germ cell)Sex-cord tumors = benign (opposite of female)
Testicular Tumors Causes
cryptorchid testicleKlinefelter’stesticular feminization
Testicular Seminoma
most common15-34; peak in 30s40-50% of all germ cell tumors Good prognosis, radiosensitive Well-circumscribed, no necrosis or hemorrhage (slick and shiny); may have trophoblastic cells; clear cell borders, T lymphocytes common, low mitosesElevated hCG>65yo (spermatocytic seminomas)
Testicular Embryonal Carcinoma
2nd most common20-25Elevated AFP and hCG Less radiosensitive than seminomas, bulky, hemorrhage and necrosisMets = hematogenous, then lymphaticEpididymis involvementMore mitoses, more pleomorphic, no distinct borders
