This study details a rare case of endogenous lipid pneumonia in a dog, characterized by foamy macrophages in the lungs. The condition was associated with heartworm infection and chronic bronchitis.
Area of Science:
- Veterinary Pathology
- Canine Respiratory Diseases
Background:
- Endogenous lipid pneumonia is an exceptionally rare condition in canine medicine.
- Previous diagnosis in dogs has been documented only once.
Purpose of the Study:
- To report and describe a second case of endogenous lipid pneumonia in a dog.
- To detail the clinical and histological findings associated with this rare condition.
Main Methods:
- Histological examination of lung tissue.
- Identification of foamy macrophages within alveolar spaces.
- Sudanophilic staining to identify lipid vacuoles.
Main Results:
- The dog presented with a persistent cough.
- Histopathology revealed alveoli filled with numerous foamy macrophages containing small sudanophilic vacuoles.
- The case was concurrent with Dirofilaria immitis infection and chronic bronchitis.
Conclusions:
- This case adds to the limited understanding of endogenous lipid pneumonia in dogs.
- The presence of foamy macrophages with sudanophilic vacuoles is a key diagnostic feature.
- Co-occurrence with Dirofilaria immitis and chronic bronchitis suggests potential contributing factors or concurrent conditions.
