Summary
Diagnosing clonal seborrheic keratosis is difficult. Dermoscopy and confocal microscopy reveal characteristic findings, enabling reliable in vivo diagnosis of this benign skin condition.
Area of Science:
- Dermatology
- Dermatopathology
Background:
- Clonal seborrheic keratosis diagnosis can be challenging clinically and histologically.
- This benign entity presents diagnostic difficulties.
Purpose of the Study:
- To describe common dermoscopic and confocal microscopy findings in clonal seborrheic keratosis.
- To highlight features aiding in the diagnosis of this specific keratosis variant.
Main Methods:
- Analysis of nine cases of clonal seborrheic keratosis.
- Utilized dermoscopy and confocal microscopy for examination.
Main Results:
- Dermoscopy showed globular-like structures and sharply demarcated borders.
- Confocal microscopy revealed intraepidermal nesting of pigmented keratinocytes.
- These findings facilitate reliable in vivo diagnosis.
Conclusions:
- Dermoscopy and confocal microscopy are valuable tools for in vivo diagnosis.
- These imaging techniques aid in identifying this variant of seborrheic keratosis.

01:16Confocal Fluorescence Microscopy
Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...
01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

Three-dimensional imaging techniques are essential in cell biology, allowing researchers to visualize intricate cellular structures with high resolution. Two prominent methods, Differential Interference Contrast Microscopy (DIC) and Confocal Scanning Laser Microscopy (CSLM), provide distinct advantages for imaging live and thick specimens, respectively.Differential Interference Contrast MicroscopyDIC microscopy enhances contrast in transparent, unstained samples by converting phase...
