CASE STUDY: CHANCROID DIAGNOSIS AND DIFFERENTIAL DIAGNOSIS

Introduction:

Chancroid is a sexually transmitted infection caused by the bacterium Haemophilus ducreyi. It is characterized by the development of painful ulcers on the genital area. Chancroid is more prevalent in developing countries, particularly in areas with limited access to healthcare services and poor socioeconomic conditions. This case study aims to diagnose a patient with chancroid and consider three differential diagnoses: Herpes Simplex Virus (HSV), Syphilis, and Human Papillomavirus (HPV).

Patient Profile:

The patient, a 35-year-old male, presents with the following symptoms:

– Painful genital ulcers with ragged edges
– Swollen lymph nodes in the groin
– Presence of yellowish discharge from the ulcers
– History of unprotected sexual intercourse with multiple partners
– No recent travel history
– No significant medical or surgical history

Subjective Assessment:

The patient complains of pain in the genital area and discomfort while urinating. The ulcers appeared approximately five days ago and have been progressively increasing in size. The patient also mentioned a recent sexual encounter with a new partner.

Objective Assessment:

Upon physical examination, the healthcare provider noted the presence of painful ulcers on the patient’s penis and scrotum. The ulcers had ragged edges and a yellowish discharge. The patient’s inguinal lymph nodes were enlarged and tender to palpation, which could be an indication of lymphadenopathy.

Diagnostic Tests:

1. Laboratory Tests:
– Blood tests to check for sexually transmitted infections (STIs) such as syphilis and HIV.
– Serological tests, including a Rapid Plasma Reagin (RPR) test, to assess for syphilis.

2. Microbiological Tests:
– Culture and Gram staining of the ulcer discharge to identify the presence of Haemophilus ducreyi.

3. Tissue Biopsy:
– A biopsy of the ulcer may be performed if the diagnosis remains unclear.

Differential Diagnosis:

1. Herpes Simplex Virus (HSV):
HSV is a viral infection characterized by recurrent painful blisters and ulcers on the genital area. Similar to chancroid, HSV can cause painful and tender lymph nodes in the groin. However, HSV lesions typically progress from small blisters to ulcers, unlike the ragged-edged ulcers seen in chancroid. HSV can be diagnosed using viral culture or Polymerase Chain Reaction (PCR) testing.

2. Syphilis:
Syphilis is a bacterial infection caused by the spirochete Treponema pallidum. Like chancroid, syphilis can cause painless genital ulcers. However, syphilis ulcers are usually firm, with smooth edges (known as a chancre). In contrast, the ulcers in chancroid are painful and have ragged edges. Diagnosis can be confirmed through serological tests such as the RPR or Venereal Disease Research Laboratory (VDRL) test.

3. Human Papillomavirus (HPV):
HPV is a viral infection that commonly leads to the development of genital warts. Although genital warts can cause discomfort and itching, they do not typically present with painful ulcers like in chancroid. A visual examination and microscopic analysis of the wart tissue can aid in the diagnosis of HPV.

Diagnosis:

Based on the patient’s symptoms, physical examination findings, and the presence of Haemophilus ducreyi in the ulcer discharge, the primary diagnosis is chancroid. Chancroid is a sexually transmitted infection that causes painful ulcers with ragged edges, swollen lymph nodes, and a yellowish discharge.
