Sigdel2 Flashcards
In epididymis. Forms abscesses
Gonorrhea
Seen in teenagers and adults. Heavy mononuclear (lymphocyte) infiltration. Edema. Neutrophils and abscesses
Mumps
Testis involved first, then spreads to epididymis. Perivascular cuffing
Syphilis
Gummas (diffuse inflammation of lymphocytes)
Syphilis
Non specific, chronic inflammation
Chronic orchitis
Rises in epididymis then moves to testis. Caseating granulomas
TB
Twisting of spermatic cord, blocking venous drainage. Causes hemorrhagic infarction. Medical emergency
Torsion
Benign. Arises in epididymis. Mesothelial in nature. Accurate diagnosis early will spare orchiectomy. Treat by simple excision
Benign paratesticular tumor - adenomatoid tumor
Increased hyaline deposition. Failure of germ cell maturation. Increased leydig cells. Tubular atrophy increases with age
Cryptochid testes
Similar to CIS. Leads to invasive tumors. Most germ cell tumors arise from this. Isochromosome 12p
Intratubular germ cell neoplasia
More aggressive tumors, but respond to therapy. Peak age 15-34 and 60+. Presents as painless testicular mass. Associated with testicular dysgenesis syndrome (cryptorchidism, hypospadias, and poor sperm quality)
Germ cell tumors
Usually benign
Sex cord (stromal) tumors
Isochromosome 12p. OCT3/4, NANOG, KIT activating mutation
Germ cell tumors
Staging is most predictive of prognosis with
Germ cell tumors
Alpha fetal protein elevated in
Yolk sac tumors
