Cutaneous melioidosis with unusual histological features

Area of Science:

• Infectious Diseases
• Microbiology
• Dermatology

Background:

• Melioidosis is caused by Burkholderia pseudomallei, a gram-negative bacillus.
• Cutaneous manifestations occur in approximately 13% of melioidosis cases.
• Typical histopathology involves suppurative or chronic granulomatous inflammation.

Observation:

• A case of cutaneous melioidosis in a young, healthy male is presented.
• The patient exhibited an unusual lymphoplasmacytic inflammatory pattern on histopathology.
• Initial treatment with oral antibiotics alone proved ineffective.

Findings:

• The case demonstrates a rare histopathological presentation of cutaneous melioidosis.
• Treatment failure with standard oral antibiotic monotherapy was observed.
• This suggests potential variations in disease presentation and treatment response.

Implications:

• Highlights the importance of considering diverse histopathological findings in melioidosis.
• Suggests that some cutaneous melioidosis cases may require more aggressive or alternative antibiotic regimens.
• Emphasizes the need for further research into atypical presentations and treatment strategies for melioidosis.
