Lymph-vessel embolism in a case of Whipple's disease
Histopathology
|January 1, 1985
Abstract:
A case of Whipple's disease is described where the lymphatics in the regional lymph nodes appear to be obstructed by embolized macrophages, containing the characteristic PAS positive bacillary material. It is suggested that the regional lymphangiectasia in Whipple's disease may in part result from such cellular embolism.
Insights
Whipple's disease involves macrophages blocking lymphatics in lymph nodes with PAS-positive material. This cellular embolism may cause lymphangiectasia, a key feature of the condition.
Area of Science:
- Gastroenterology and Infectious Diseases
- Pathology and Cellular Biology
Background:
- Whipple's disease is a rare systemic bacterial infection.
- It primarily affects the small intestine but can impact multiple organs.
Observation:
- A case study detailing Whipple's disease is presented.
- Examination of regional lymph nodes revealed lymphatic obstruction.
Findings:
- The obstruction was caused by macrophages laden with periodic acid-Schiff (PAS) positive bacillary material.
- These macrophages appeared to have embolized within the lymphatic vessels.
Implications:
- The findings suggest a novel mechanism for lymphangiectasia in Whipple's disease.
- Cellular embolism by infected macrophages may contribute to lymphatic dysfunction.
