*Approximately 25% of patients with lymphadenopathy may present with abscesses in lymph nodes or ruptured buboes


Approximately one third of the infected individuals will develop enlargements of the [[inguinal]] [[lymph nodes]], the nodes located in the fold between the leg and the lower abdomen.
Half of those who develop swelling of the inguinal lymph nodes will progress to a point where the nodes rupture through the skin producing draining abscesses. The swollen lymph nodes and abscesses are often referred to as buboes.

Overview

Physical Examination

Vital Signs

Typically normal

Skin

A patient may present with either of the following types of lesions on the genitals, depending on the stage of infection:[1][2]

Ulcer characteristics:[3]

  • Ranges in size from 3 to 50 mm (1/8 to 2 inches) in diameter
  • Painful
  • Soft, nonindurated
  • Irregular border
  • Sharp margins
  • Grey/yellow exudate
  • Males typically have a single ulcer
  • Females typically have multiplee ulcers
  • May look similar to syphilitic chancre

Common locations in males

Common locations in females

  • labia majora (most common). "Kissing ulcers" may develop, defined as ulcers that occur on opposing surfaces of the labia.
  • labia minora
  • Perineal area
  • Inner thighs (least common)

Other Signs

  • Inguinal lymphadenitis in approximately 50% of patients, known as buboes (typically unilateral and predominantly in males)[4]
  • Approximately 25% of patients with lymphadenopathy may present with abscesses in lymph nodes or ruptured buboes
