Papillary Dermis

Papillary Dermis

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 and...

Pathophysiology of Peptic Ulcer Disease: Mucosal Defense Factors

Pathophysiology of Peptic Ulcer Disease: Mucosal Defense Factors

Peptic ulcer disease, commonly called PUD, represents a multifaceted condition characterized by disruptions in the lining of the gastrointestinal (GI) tract. Central to the protection of the gastrointestinal lining is the mucosal-bicarbonate barrier. This physiological defense mechanism is a formidable shield against the corrosive effects of gastric acid and pepsin secretion in the stomach. Its role is pivotal in maintaining the structural integrity of the stomach's inner lining. Bicarbonate,...

Cirrhosis I: Introduction

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...

Summary

Morphea, a skin condition causing excess collagen, can rarely affect oral mucosa. This case highlights isolated oral morphea, emphasizing its potential for severe dental complications.

Area of Science:

Dermatology
Oral Medicine

Background:

Morphea is a fibrosing skin condition characterized by excessive collagen deposition.
While typically limited to the skin, rare cases involve mucosal surfaces.

Observation:

A woman presented with a whitish, indurated plaque on her oral mucosa, affecting the hard palate and upper vestibular region.
This led to dental mobility and root exposure of several teeth.

Findings:

Cone beam computed tomography revealed bone resorption in the maxilla.
Microscopy showed epithelial atrophy, dermal fibrosis extending into the submucosa, and hyalinization of subepithelial collagen.

Implications:

This case expands the known clinical spectrum of morphea.
It represents the first documented instance of isolated oral morphea.
Early recognition is crucial to prevent significant local oral complications and manage dental issues.
