==Overview==
==Overview==
Scrotal masses must be differentiated from other diseases that cause scrotal swelling,scrotal pain,such as testicular tortion ,epididimitis,testicular tumors,inguinal herniation and many other diseases.


==Differential Diagnosis==
==Differentiating Scrotal masses from the other Diseases==
 
[[Scrotal mass|Scrotal masses]] must be differentiated from other diseases that cause scrotal swelling,scrotal pain,such as [[Testicular cancer|testicular tortion]] ,[[Epidemic abscess|epididimitis,]]<nowiki/>testicular tumors,[[Inguinal canal|inguinal herniation]] and many other diseases.
*The table below summarizes the findings that differentiates [[Scrotal mass (patient information)|scrotal mass]] according to the clinical features, laboratory findings, imaging features, [[Histological section|histological features]], and [[genetic]] studies.

Overview

Scrotal masses must be differentiated from other diseases that cause scrotal swelling,scrotal pain,such as testicular tortion ,epididimitis,testicular tumors,inguinal herniation and many other diseases.

Differentiating Scrotal masses from the other Diseases

Scrotal masses must be differentiated from other diseases that cause scrotal swelling,scrotal pain,such as testicular tortion ,epididimitis,testicular tumors,inguinal herniation and many other diseases.

  • Serum immunofluorescence antibody testing.
  • Phen sign +ve
  • Testicular atrophy
  • Infertility
Testicular Torsion[15][16][17][18][19][7] Unilateral Sudden - Absent + + +

Blood in semen may be present

Absent -
  • Normal
  • Absent or decreased arterial perfusion of the testis
  • In the first 4 hours: testicular parenchyma shows edema and and desquamation of the germ cells
  • 4-8 hours partial necrosis of germ cells.
  • >24 hrs: necrosis
  • Phen sign +ve
Hematocele[20][21]
[22][23][24]
Unilateral or bilateral Sudden - Absent + + +

Blood in semen

Absent -
  • Urinalysis may be the only indication of injury to urinary tract
  • Hematuria.
Scrotal wall thickening and testicular hematoma Testicular trauma related to:
  • Increased destruction and fibrosis of the dartos fascia,.
  • Dense inflammatory cells, necrotic areas and destruction of the muscular layer.
  • Ultrasonography: to check for testicular rupture.
_
Incarcerated Hernia[25][26] Unilateral Sudden + Absent + + - Absent +
  • Normal
  • Normal
- -
  • Groin ultrasound or CT scan show presence of bowel and omentum.
  • Valsalva maneuvers performed while palpating the inguinal canal will push a hernia against the examiner's finger.

  • CBC-Leukocytosis
  • raised CRP
  • Immunofluorescent antibody testing
  • Urine analysis and culture - normal
  • Increased blood flow in affected side
-
  • Culture of the organism from blood.
Antibodies are detected using:
  • Serum agglutination (standard tube agglutination)
  • Enzyme-linked immunosorbent assay
  • Rose Bengal agglutination
  • Coombs test
  • Immunocapture agglutination (Brucellacapt)
  • 2-mercaptoethanol agglutination

  • >24 hrs: necrosis
  • scrotal ultrasound shows the torsed appendage as a lesion of low echogenicity with a central hypoechogenic area.
  • Scrotal wall mayshow the classical "blue dot" sign, which is due to infarction and necrosis of the appendix testis
