Generalized Leishmanides in an Immunodeprived Man.

Area of Science:

• Dermatology
• Infectious Diseases
• Otolaryngology

Background:

• Leishmaniasis is an uncommon parasitic infection with varied clinical presentations.
• Cutaneous leishmaniasis is the most common form, but laryngeal involvement is rare.
• Human immunodeficiency virus (HIV) infection can alter the clinical course of leishmaniasis.

Observation:

• A 50-year-old HIV-positive male presented with a generalized eruption of papules and plaques.
• Extensive diagnostic workup, including culture, microscopy, immunohistochemistry, and PCR, failed to identify any microorganism.
• The patient's clinical presentation was initially attributed to an unknown cause.

Findings:

• Despite negative diagnostic tests for common pathogens, the patient was diagnosed with laryngeal leishmaniasis.
• This diagnosis was supported by the eventual improvement of cutaneous lesions following leishmaniasis treatment.
• The case highlights a rare manifestation of leishmaniasis in an immunocompromised individual.

Implications:

• This case underscores the importance of considering rare diagnoses like laryngeal leishmaniasis in HIV-positive patients with unusual dermatological findings.
• It emphasizes the diagnostic challenges when conventional methods fail to detect the causative agent.
• Successful treatment of leishmaniasis suggests a potential link between the parasitic infection and the observed cutaneous manifestations.
