Penicillium marneffei infection diagnosed by polymerase chain reaction from the skin specimen

Area of Science:

• Mycology
• Infectious Diseases
• Immunocompromised Hosts

Background:

• Penicillium marneffei is an emerging fungal pathogen endemic to Southeast Asia.
• Disseminated infections typically occur in immunocompromised individuals, particularly those with advanced human immunodeficiency virus (HIV) infection.
• Cutaneous manifestations are common but can be diverse.

Observation:

• A patient diagnosed with acquired immunodeficiency syndrome (AIDS) presented with extensive, disseminated skin eruptions.
• The widespread nature of the lesions suggested a systemic infectious process.

Findings:

• Skin biopsy specimens were analyzed using molecular techniques.
• Polymerase chain reaction (PCR) with specific primers successfully identified Penicillium marneffei in the biopsy samples.
• This molecular confirmation facilitated accurate diagnosis of the fungal infection.

Implications:

• Early and accurate diagnosis of Penicillium marneffei infection is crucial for effective management in immunocompromised patients.
• Polymerase chain reaction offers a sensitive and specific method for identifying P. marneffei in clinical specimens.
• Understanding the clinical presentation, including disseminated skin lesions, aids in recognizing this opportunistic infection.
