Study Notes
Male Genital Tract Diseases
- Cryptorchidism: Failure of testicular descent into the scrotum
- Benign Prostatic Hyperplasia (BPH): Primarily caused by increased androgen levels, not chronic prostatitis or chronic pelvic pain syndrome
- Prostatic Carcinoma (Prostate Cancer): Primarily arises from the peripheral zone of the prostate
- Nodular Prostatic Hyperplasia: Arises from the central zone, periurethral zone, and transitional zone of the prostate; not the peripheral zone
- Prostatic Carcinoma Substrate: Excessive androgen-dependent growth of stromal and glandular elements, not chronic prostatitis or bacille Calmette-Guérin
- Cryptorchidism Consequences: Testicular carcinoma, infertility, and tubular atrophy; not prostatitis or phimosis
- Testicular Germ Cell Tumors: Subclassified into seminomas and nonseminomas
- Seminoma Gross Appearance: Soft consistency, well-demarcated, gray-white tumors that bulge from the cut surface, may contain coagulation necrosis
- Seminoma Microscopic Features: Large, uniform cells with distinct cell borders, round nuclei, prominent nucleoli
- Yolk Sac Tumors: Most common primary testicular neoplasm in children under 3 years of age; often admixed with embryonal carcinoma in adults, and large on gross inspection, have Schiller-Duvall bodies microscopically
- Nodular Hyperplasia of Prostate: Appears in glands in the central zone; feels palpable during rectal exam; causes early urinary obstruction
Prostate Carcinoma
- Characteristics: Occurs mainly in men older than 50 years of age; advanced lesions can appear firm, gray-white foci; lesions are often without well defined margins and infiltrate adjacent glands.
- Malignant vs. Benign Prostate Glands: Malignant glands are typically smaller than benign glands; malignant glands are crowded together, lack branching, and lack papillary infoldings; benign glands are lined by a single layer of uniform cuboidal or columnar epithelium.
- Microscopic Features (Prostate Carcinoma): Nuclei are often enlarged and contain one or more prominent nucleoli; mitotic figures are uncommon; irregular or ragged glandular structures are frequent; pleomorphism is not marked.
Embryonal Carcinoma Characteristics
- More aggressive than seminomas: Primary tumors are smaller than seminomas; do not replace entire testis; frequently spread into epididymis and Tunic Albuginea
- Characteristics: Well formed glands are present, often variegated (appearing different parts of the tumor), poorly demarcated margins, foci of hemorrhage are common
Testicular Tumors
- Composition: Germ cells are the source of 95% of testicular tumors; germ cell tumors may be composed of a single histologic pattern in 60% of cases, a mixed histologic pattern in about 40%.
Syphilis
- Neurosyphilis: Late tertiary phase, affects the basal ganglia, hippocampus, and brain stem, diffuse cerebral cortical neuronal loss, meningovascular lesions and parenchymal destruction
- Primary Syphilis: Incubation period: 2-6 weeks; incubation period after: 10-20 weeks; characterized by a hard chancre, or condyloma lata, and maculopapular rash
- Secondary Syphilis: Incubation period: 2-6 weeks; incubation period after: 10-20 weeks; characterized by a hard chancre, or condyloma lata, and maculopapular skin rash
- Tertiary Syphilis: characterized by gummas, cardiovascular damage, and neurosyphilis
Female Genital Tract Diseases
- Cervical Carcinoma: Typically begins at the junction of the ectocervix and endocervix; important prognostic factors include tumor size, tumor location in breast, and lymph node involvement, along with cancer grade.
- Endometrial Carcinoma: Most cases occur in postmenopausal women; frequently preceded by endometrial hyperplasia; can metastasize via lymphatic and/or hematogenous routes; stage of the tumor is the most important prognostic factor
- Cervical Squamous Cell Carcinoma: Commonly preceded by squamous cell dysplasia; associated with Human Papillomavirus (HPV); Early age of first intercourse is a risk factor. Most cases occur in women under 65, Pap smears are crucial for screening.
- Ovarian Neoplasms: Most are malignant tumors of germ cells.
Pathology of Skin and Soft Tissues
- Macule: Flat, circumscribed lesion less than 5mm in diameter, which differs in color from the surrounding skin
- Patch: Flat, circumscribed lesion more than 5mm in diameter, which differs in color from the surrounding skin
- Papule: Elevated, dome-shaped or flat-topped lesion less than 5mm in diameter
- Nodule: Elevated, dome-shaped or flat-topped lesion more than 5mm in diameter
- Vesicle: Fluid-filled raised lesion less than 5mm in diameter.
- Bulla: Fluid-filled raised lesion more than 5mm in diameter
- Blister: Fluid-filled raised lesion, less than or greater than 5mm.
- Scale: Thickened skin with rough texture, usually due to repetitive friction
- Lichenification: Thickened skin with rough texture, usually due to repetitive friction
Other
- Graves' Disease: Manifestations include infiltrative ophthalmopathy (eye changes), tachycardia (increased heart rate), and diffuse, infiltrative dermopathy.
- Cushing's Syndrome: Characterized by fatigue, weakness, elevated blood glucose, and hypertension, along with a protruding hump between the shoulders.
- Simmonds Disease: Dysfunction of the pituitary gland; characterized by fatigue and weakness, and various other metabolic symptoms
- Addison's Disease: Characterized by fatigue, weakness, hypotension; bronze color of the skin,
