[The morphology of mesenteric lymph nodes in Whipple's disease]
Abstract:
A patient aged 45 suffering from Whipple's disease is described. The disease has been diagnosed on the basis of morphologic examination of a biopsy specimen of the small intestine mesenteric lymph node. The patient had suffered from the disease for 14 years; during the last 6 months he developed symptoms of the malabsorption syndrome with diarrhea and steatorrhea. The lymph nodes contained numerous macrophages with PAS-positive glycoprotein granules in the cytoplasm, small cavities filled with lipids; electron microscopy has revealed bacillus-like bodies in the macrophages and outside the cells. After the disease has been diagnosed, the patient has been administered a course of tetracycline therapy, that resulted in an improvement of his status.
Insights
Whipple's disease, a rare bacterial infection, was diagnosed in a 45-year-old patient after 14 years of symptoms. Treatment with tetracycline improved the malabsorption syndrome, highlighting effective therapeutic options.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Pathology
Background:
- Whipple's disease is a rare, chronic bacterial infection with protean manifestations.
- Diagnosis often relies on characteristic histopathological findings in affected tissues.
Observation:
- A 45-year-old patient presented with a 14-year history of Whipple's disease.
- Recent symptoms included malabsorption syndrome, diarrhea, and steatorrhea.
- Mesenteric lymph node biopsy revealed macrophages with PAS-positive granules and lipid vacuoles.
Findings:
- Electron microscopy identified bacillus-like bodies within macrophages and extracellularly.
- These findings confirmed the diagnosis of Whipple's disease.
Implications:
- Early and accurate diagnosis is crucial for effective management.
- Tetracycline therapy demonstrated efficacy in resolving malabsorption symptoms.
- This case underscores the importance of considering Whipple's disease in patients with prolonged unexplained gastrointestinal issues.
