Tumors
Nodular hyperplasia/Benign prostatic hyperplasia
General
Very common (20% 40's - 70% of 60's)
Pathology
Nodular hyperplasia, stroma&glands double layer of epithelium preserved Transition zone
Carcinoma
General
Very common, age (20%-50's, 70%-70's) Latent vs clinically significant Problem of overtreatment LATENT: low grade, low volume, low PSA DRE/PSA Utility & Limitations reference values the total PSA range of 4.0 to 10.0 ng/mL has been described as a diagnostic "gray zone," false+ & false- results PSA derivatives & kinetics free: total PSA (F/T ratio) density velocity - the rate of change in PSA level doubling time not specific for disease progression
Pathology
Adenocarcinoma small infiltrating glands, architectural distortion single layer of cells large nuclei with prominent nucleoli AdenoCa, LOW MAG AdenoCa, High MAG Gleason grading

of prostate carcinoma) Architectural patterns 3 - donuts 4 - pretzels 5 - solid sheets or single cells GLEASON SCORE sum of the two most prevelent patterns Peripheral zone (70% OF GLAND VOLUME, 80% OF CANCERS) Precursors: HGPIN, Adenosis (AAH) stong association but the risk of progression unknown Spread Role of pathologists Biopsy, core bx diagnosis GS prognostic grouping I - 3+3 II - 3+4 III - 4+3 IV - 4+4 V - 4+5, 5+4; 5+5 GS and tumor volume Key factors in management of patients together with age, PSA level, clinical stage Transurethral resection of prostate (TURP) exclusion of neo Radical prostatectomy Pathological Stage (pTNM) Gleason score Margin status

Zonal anatomy Histology Histology
Testis & paratesticular tissues
Congenital anomalies
Testicular dysgenesis
abnormal embryonic development of gonads (hypoplastic or incompletely developed + hypogonadism)
result in DISORDERS OF SEX DEVELOPMENT
Cryptorchidism
component of Testicular Dysgenesis Syndrome
TDS spectrum ENDOCRINE DISRUPTORS Xenoestrogens: , PCB, Bisphenol A, Phtalates
NON-PALPABLE ABSENT TESTICLE/TESTES IN THE SCROTUM
(EMPTY SCROTUM)
un-/maldescended, ectopic, regressed or missing (anorchia) atrophy or fibrous streak or complete lack of testicular structures
Vanishing testes syndrome/testicular regression syndrome
At least 5% of cryptorchid testes "vascular accident"(va) during emryo or fetal development leading to disapperance of initially normal testicle phenotype depends on the time of the va - variants from unilateral anorchia through ambiguous gentilia to female internal& external phenotype
ORCHIOPEXY to prevent complications
infertility (<2yo) germ cell tumors (<5yo)
Inflammatory
Epididymo-orchitis
Epididymitis
Tuberculosis
Orchitis
viral: mumps
Infectious (Non-specific Gram- bacilli and pyogenic cocci, viruses or STD)
Non-infectious (vasculitis, trauma, idiopathic)
Vascular
Torsion
anomalous testicular suspension defect
torsion
incompletely descended testis is more prone to torsion during the fetal period
Tumors
GERM CELL NEOPLASIA IN SITU (GCNIS)
Neoplasms
Germ cell tumors (GCTs) >95%
General Most common cancer in young males Aggresive but curable AGE DIFFERENCES Biomarkers: AFP, bHCG, LDH Pathology Pure (40%) Seminoma (>90% of pure, 35-40% of all) seminoma Non-seminomatous Embryonal carcinoma EC Yolk sac tumor YST Choriocarcinoma CCH Teratoma Dermoid cyst Mixed most common (60%) Precursor: IGCN Spermatocytic seminoma/SPERMATOCYTIC TUMOR distinct entity, different molecular pathway, elderly
Sex cord stromal tumors <5%
Leydig cell tumor (most common SCST)
Secondary

Celes and cysts

Epidymoorchitis Inguinal hernia
HYPOGONADISM
(gonadal failure)
PRIMARY (hypergonadotropic)
genetic syndromes maldescended testes vanishing testes syndrome external insults (eg inflammation, ischaemia) autoimmune Sertoli cell only syndrome
SECONDARY (hypogonadotropic) presentation depends on the age of development

Preinvasive/precursor lesions -PENILE INTRAEPITHELIAL NEOPLASIA (PeIN)
Clinical presentations (variable)
HPV-related (oncogenic, high-risk types) Bowenoid papulosis - transitional state between a genital wart and Bowen disease,
pigmented papules on the shaft, spontaneous regression, younger (30's-40's) Bowen's disease - scaly hyperkeratotic plaque, usually on shaft of penis Erytroplasia of Queyrat - erythematous plaque on the glans and prepuce HPV-unrelated Phimosis with leukoplakia - whitish patch or plaque on the glans or prepuce
Pathology (common)
1.TRANSEPIDERMAL CYTOLOGICAL ATYPIA, 2.ABNORMAL PROLIFERATION, 3.ABNORMAL MATURATION PeIN, histopatho HPV-related (particularly (HPV-16 and 18), looks like HGPIN in cervix not related to HPV
