o Scrotal transillumination
|
scrotal lesions that transilluminate include hydrocele, spermatocele and varicocele.
|
|
o Testicular torsion
|
acute, unilateral scrotal pain usually occurring in adolescent due to sudden twisting of spermatic cord producing testicular ischemia. The involved testicle is tender, edematous and indurated; elevation of testicle does not relieve pain.
|
|
o Testicular mass or nodule
|
non-tender, solid testicular mass is assumed to be cancer until proven otherwise. Testicular cancer is the most common solid cancer in men 15-35 years of age.
|
|
o Varicocele
|
common condition due to dilatation of pampiniform plexus of spermatic veins, recognized as scrotal enlargement that feels like “bag of worms”. In addition, varicoceles disappear with recumbence, and the examining finger cannot find the superior margin of lesion. Usually asymptomatic and more often left-sided, it can be a cause of infertility. Rarely may signal left renal cell carcinoma if cancer invades left renal vein and impedes left testicular venous drainage.
|
|
o Genital wart
|
reflecting papilloma virus (HPV) infection, this is a sexually transmitted disease and a risk factor for penile carcinoma (and for cervical cancer in sex partners).
|
|
o Herpes simplex lesion
|
usually occurs in the form of multiple painful vesicles due to HSV-2 infection; primary infection occurs about 6 days after exposure and is very painful with associated dysuria, fever, inguinal adenopathy and headache (occasionally with frank viral meningitis). Recurrent disease has milder symptoms. Asymptomatic patients may shed virus and transmit disease with sexual contact. The attack rate is 70% in sero-negative exposed subjects.
|
|
o Paraphimosis
|
inability to replace a retracted foreskin; typically a very painful condition, this can be a medical emergency as increasing penile edema will result in penile ischemia and necrosis if not reduced.
|
|
o Penile cancer
|
squamous cell carcinoma in most, begins as a painless papule that progresses. HPV DNA is found in 30-50% of lesions.
|
|
o Phimosis
|
inability to retract foreskin, this is a strong risk factor squamous cell carcinoma of the penis.
|
|
o Syphilitic chancre
|
painless lesion occurring ~21 days after exposure reflecting site of spirochete entry. Begins as a solitary papule that ulcerates, it is indurated and without exudate. It will heal in 4-8 weeks without treatment.
|
|
o Direct inguinal
|
usually due to congenital weakness in abdominal wall musculature, the hernia proceeds directly through abdominal wall. The hernia sac will touch the side of the examining finger in the inguinal canal.
|
|
o Indirect inguinal
|
usually acquired and more common in elderly and obese man, the hernia proceeds indirectly into scrotal sac via the inguinal canal. The hernia sac will touch the tip of the examining finger in the inguinal canal.
|
|
o Femoral
|
more common in women, this hernia occurs through the femoral canal and is inferior to the inguinal ligament (latter feature differentiates this from above inguinal hernias).
|
|
• Differential diagnosis of palpable kidneys
|
normal kidneys are not palpable (except in extremely thin individuals); palpable kidneys are found in adult polycystic kidney disease, renal cell carcinoma, angiomyolipoma (tuberous sclerosis) and the rare entity, xanthogranulomatous pyelonephritis.
|
|
• Costo-vertebral angle tenderness
|
due to swelling of renal capsule and elicited by percussion with medial aspect of fist, this is most commonly due to pyelonephritis, but can also be caused by hydronephrosis.
|
|
• Uremic frost
|
white powdery dusting of the skin most common in patients with severe renal failure with BUN > 200 mg/dL (reflects crystallized urea from sweat).
|
|
|
