|---|---|
| 1. Penis Malformations 2. associated with undescended testes 3. increased risk of urinary tract infections (UTIs) and infertility | Hypospadias and Epispadias |
| urethral opening on the ventral surface of the penis | Hypospadias |
| urethral opening on the dorsal surface of the penis | Epispadias |
| Balanitis/balanoposthitis | inflammation of the glans penis |
| Causes of Balanitis/balanoposthitis | poor hygiene and lack of circumcision |
| Penile fibromatosis resulting in curvature of the penis | Peyronie disease |
| a. Warty, cauliflower-likegrowth b. Human papilloma virus (HPV) serotypes 6 and 11 | Condyloma acuminatum |
| a. Uncommon in the United States b. Increased risk in uncircumcised males c. Human papilloma virus (HPV) serotypes 16 and 18 d. Precursors: Bowen disease,bowenoid papulosis, erythroplasia of Queyrat | Squamous cell carcinoma (SCC) |
| a. Dilated vein within the spermatic cord b. May cause infertility | Testes Varicocele |
| fluid within the tunica vaginalis | Hydrocele |
| dilated efferent duct in the epididymus containing sperm | Spermatocele |
| i. Age <35: Neisseria gonorrhoeae and Chlamydia trachomatis ii. Age >35: Escherichia coli and Pseudomonas | Acute Epididymitis |
| Chronic epididymitis | TB |
| Orchitis | viral-mumps |
| a. Twisting of the spermatic cord b. May be associated with physical activity or trauma c. Painful hemorrhagic infarction | Testicular torsion |
| 1. Clinical presentation a. Firm, painless testicular mass b. Nonseminomatous tumors may present with widespread metastasis. | Testicular Cancer |
| Risk factors a. Cryptorchidism: (5-10 times increased risk!) b. Testicular dysgenesis (testicular feminization and Klinefelter syndrome) c. Caucasians> African Americans d. Family history | Testicular Cancer |

| 1. Most common germ-cell tumor in adults age 15-35 ii. Gross: large, gray-tan, bulky masses | Seminoma |
| Micro . Polygonal germ cellswith clear cytoplasm and round nuclei . Arranged in lobules, which are separated by fibrous septae . Lymphocytes,granulomas, and giant cells may be seen | Seminoma |
| Tumor marker: placental alkaline phosphatase (PLAP) v. Treatment: chemo and radiosensitive vi. Prognosis: excellent;early stage 95% cure | Seminoma |
| Variant of seminoma | spermatocytic seminoma |
| spermatocytic seminoma | older men, excellent prognosis |
| i. Age 20s-40s ii. Gross: bulky masses with hemorrhage and necrosis iii. Micro: large primitive cells iv. Tumor markers: nonspecific, may have alpha-fetoprotein (AFP) and/or beta human chorionic gonadotropin (j3-hCG) v. More aggressivethen seminoma | Embryonal carcinoma |
| Highly malignant with widespread metastasis ii. Gross: often small primaries with extensivehemorrhage and necrosis iii. Micro: proliferation of syncytiotrophoblasts and cytotrophoblasts iv. Tumor marker: B-hCG v. Hematogenous spread to lungs and live | Choriocarcinoma |
| i. Most common germ-cell tumor in children ii. Good prognosis in children iii. In adults, it is often mixed with other components iv. Micro: Schiller-Duval bodies v. Tumor marker: alpha-fetoprotein (AFP | Yolksac tumor (endodermal sinus tumor) |
