A typical presentations may sometimes occur so Chancroid should always be kept in mind as a differential diagnosis while dealing with genital ulcer disease (GUD) patients as Microbiological evidence may not always be available. We present two cases with GUD. Swabs were collected from the base and margins of the penile ulcers and sent to the bacteriology laboratory for Gram staining and aerobic routine culture. Gram-stained smears revealed numerous Gram-negative coccobacilli in a typical railroad track/school of fish appearance suggestive of Haemophilus ducreyi infection. No growth was observed on aerobic routine culture. The patients were started on single-dose azithromycin as per National AIDS Control Organisation (NACO) guidelines.
