Podoconiosis: Clinical spectrum and microscopic presentations

Area of Science:

• Dermatology
• Tropical Medicine
• Pathology

Background:

• Podoconiosis is a prevalent skin Neglected Tropical Disease (NTD) affecting barefoot farmers in tropical regions.
• It causes debilitating lymphoedema, yet its clinical and histopathologic aspects remain understudied.
• This research systematically documents the diverse clinical and histopathologic spectrum of podoconiosis.

Purpose of the Study:

• To systematically document the clinical presentation of podoconiosis.
• To describe the histopathologic correlates of podoconiosis across different disease stages.
• To provide a basis for improved patient classification and prognostic assessment.

Main Methods:

• A cross-sectional study was conducted in Durbete, Ethiopia.
• Dermatologists performed clinical assessments, including patient history, physical examination, and filariasis testing.
• Skin biopsies were obtained for detailed histopathologic examination.

Main Results:

• 289 patients were recruited, with 61.6% in stages 1-2 and 38.4% in stages 3-5.
• Warty lesions (77.5%) and nodules (39.4%) were common; 86.9% had bilateral leg involvement.
• Histopathology in advanced stages revealed epidermal/dermal thickening, inflammation, lymphatic vessel changes, and sclerosis.

Conclusions:

• This study provides a comprehensive description of podoconiosis's clinical and histopathologic spectrum.
• Findings detail varied presentations and stage-specific histopathologic changes.
• The observations serve as a guide for classifying patients for prognostic assessment and treatment planning.
