Overview
Patients may present with erythematous papules, pustules, or ulcers depending the stage of the chancroid. Ulcers are soft with irregular but sharp margins, and looks similar to a syphilitic chancre. Males typically have 1 ulcer while females typically have multiple. The most common location in males is the foreskin (prepuce). The most common location in females in the labia majora. Approximately 50% of patients may present with swollen inguinal lymph nodes.
Physical Examination
Vital Signs
Typically normal
Skin
A patient may present with either of the following types of lesions on the genitals (or extremities in cases of cutaneous limb ulcers[1][2]), depending on the stage of infection:[3][4]
Ulcer characteristics:[5]
- 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
- Foreskin (prepuce) (most common)[6]
- Groove behind the head of the penis (coronal sulcus)
- Shaft of the penis
- Head of the penis (glans penis)
- Opening of the penis (urethral meatus)
- Scrotum (least common)
Common locations in females
- Labia majora (most common). "Kissing ulcers" may develop, defined as ulcers that occur on opposing surfaces of the labia.[6]
- 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)[7]
- Approximately 25% of patients with lymphadenopathy may present with abscesses in lymph nodes or ruptured buboes
