Pulmonary Malakoplakia Associated with Peripheral Cysts in an Immunocompetent Patient: A Case Report

Area of Science:

• Pulmonology
• Pathology
• Rare Diseases

Background:

• Pulmonary malakoplakia is an uncommon lung condition.
• It predominantly affects immunocompromised individuals.
• Differential diagnosis often includes malignant neoplasms.

Observation:

• This study details a rare case of pulmonary malakoplakia in a young, immunocompetent patient.
• The patient presented with an irregular pulmonary nodule featuring peripheral cysts.
• Surgical intervention preceded the definitive diagnosis.

Findings:

• The case represents the first published description of pulmonary malakoplakia presenting with peripheral cysts.
• Histopathological examination was crucial for accurate diagnosis, distinguishing it from cancerous growths.
• The condition's rarity and atypical presentation posed diagnostic challenges.

Implications:

• This case expands the known clinical spectrum of pulmonary malakoplakia.
• It underscores the importance of considering rare diagnoses in pulmonary nodule evaluation.
• Accurate histopathological diagnosis is essential for appropriate patient management.
