Abstract:
We present 4 patients with pulmonary alveolar proteinosis and AIDS which died in Infectious Disease Hospital Iaşi in the interval January 2002-March 2003. The pulmonary tissue from the necropsy exam was stained with H.E., PAS, Alcian blue and Mucicarmine. The macroscopical examination revealed multiple yellow-gray nodular areas (>2 cm) of consolidation. Microscopically, the alveoli were filled with a delicate, granular, acidophil material that was periodic acid Schiff (PAS) positive. The intraalveolar material was Alcian blue and Mucicarmine negative, too.
Insights
Pulmonary alveolar proteinosis in patients with Acquired Immunodeficiency Syndrome (AIDS) presents as lung consolidation. Microscopic analysis revealed a granular, PAS-positive material filling the alveoli.
Area of Science:
- Pulmonology
- Pathology
- Infectious Diseases
Context:
- Pulmonary alveolar proteinosis (PAP) is a rare lung disease.
- Acquired Immunodeficiency Syndrome (AIDS) can predispose individuals to opportunistic infections and other complications.
- This study examines PAP in the context of AIDS.
Purpose:
- To describe the pathological findings of pulmonary alveolar proteinosis in patients with AIDS.
Summary:
- Four patients with AIDS who died from pulmonary alveolar proteinosis were studied.
- Autopsy revealed macroscopic yellow-gray nodular consolidation in the lungs.
- Microscopic examination showed alveoli filled with a granular, acidophilic, Periodic Acid Schiff (PAS)-positive material.
Impact:
- Highlights the characteristic histopathological features of PAP in AIDS patients.
- Contributes to the understanding of rare pulmonary manifestations in immunocompromised individuals.
- Informs diagnostic approaches for similar cases.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
