    This study details a simple proximal nail fold biopsy technique for analyzing capillary structure. Findings reveal normal epidermal and dermal components, including unique sweat drainage, nerve structures, and capillary basal lamina multiplication.

    Area of Science:

    • Dermatology
    • Microscopy
    • Histochemistry

    Context:

    • Capillaroscopy and fluoroscopy are used to observe normal nail fold capillaries.
    • A simple proximal nail fold biopsy technique is described.
    • This technique offers no disadvantage to patients.

    Purpose:

    • To describe a simple and non-disadvantageous proximal nail fold biopsy procedure.
    • To analyze the normal structure of proximal nail fold capillaries using multiple microscopy techniques.

    Summary:

    • The study outlines a straightforward proximal nail fold biopsy method.
    • Histochemistry, electron microscopy, and direct immunofluorescence were employed for tissue analysis.
    • Normal epidermal and dermal components were identified in healthy subjects.
