Pulmonary alveolar proteinosis: a case report

Area of Science:

• Pulmonology
• Rare Diseases

Background:

• Pulmonary alveolar proteinosis (PAP) is a rare diffuse interstitial lung disease.
• Characterized by alveolar obstruction from pulmonary surfactant accumulation.

Observation:

• A 30-year-old male sugar cane worker presented with dyspnea and cough.
• Clinical findings included cyanosis, rales, and a crazy paving pattern on CT scan.
• Bronchoalveolar lavage revealed characteristic foamy material.

Findings:

• Transbronchial biopsy confirmed pulmonary alveolar proteinosis.
• The patient responded favorably to whole lung lavage therapy.

Implications:

• PAP is a rare but significant condition requiring careful diagnosis and treatment.
• Whole lung lavage is an effective therapeutic option for this challenging disease.
