Overview
Differential Diagnosis of Chancroid
Chancroid must be differentiated from other diseases that cause genital ulcers:
- Syphilis
- Herpes simplex
- Dermatologic aspects of Behçet's disease
- Dermatologic manifestations of Lymphogranuloma venereum
- Donovanosis
- Fixed drug eruption
Syphilitic chancres most closely resemble and chancroid lesion. A comparison is found below:
| Clinical Characteristic | Disease | |
|---|---|---|
| Syphilitic Chancre | Chancroid | |
| Mode of Transmission | Mainly sexual | Mainly sexual |
| Cause | Treponema pallidum | Haemophilus ducreyi |
| Lesion Type | Pustules that may progress to ulcers | Pustules that may progress to ulcers |
| Lesion Location | Genitals | Typically genitals; may occur on limbs |
| Lesion Size | Typically 1-2 cm in diameter | Typically 1-2 cm in diameter |
| Lesion Number | 1-4 | Mulpitle |
| Lesion Exudate | Typically grey/yellow purulent exudate | Typically non-exudative |
| Lesion Tenderness | Typically indurated | Typically soft |
