Summary
Dermoscopy reveals varied features in mucosal lichen planus (LP), with Wickham's striae being the hallmark. Understanding these patterns aids in differentiating mucosal LP from other inflammatory conditions.
Area of Science:
- Dermatology
- Dermoscopy
- Oral Medicine
Background:
- Lichen planus (LP) is a chronic inflammatory condition affecting skin and mucous membranes.
- Literature on dermoscopic aspects of mucosal LP is limited.
- This study addresses the scarcity of information on mucosal LP dermoscopy.
Purpose of the Study:
- To describe the dermoscopic features of mucosal lichen planus.
- To provide a comprehensive literature summary on mucosal LP dermoscopy.
Main Methods:
- Cross-sectional, multicenter study.
- Inclusion of patients with histologically confirmed mucosal LP.
- Dermoscopic examination performed on 27 patients.
Main Results:
- Wickham's striae (WS) observed in 91% of cases.
- Common vascular patterns included linear (85%) and dotted (70%) vessels.
- Pigmented structures like globules and dots were noted in 41% of patients.
Conclusions:
- Mucosal LP exhibits diverse dermoscopic findings.
- Wickham's striae are characteristic, with unique patterns in mucosal LP compared to cutaneous LP.
- Dermoscopy aids in distinguishing mucosal LP from other oral inflammatory diseases.

Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...

The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
