Complications include urethral fistulas and scars on the foreskin of the penis in uncircumcised males. Patients with chancroid should also be checked for other sexually transmitted infections, including syphilis, HIV, and genital herpes.
Chancroids in persons with HIV may take much longer to heal.
Untreated chancroid often results in ulcers occurring on the genitals. Sometimes the ulcers persist for weeks or months.
