Summary
Pemphigus vulgaris, an autoimmune skin disease, rarely appears over surgical scars. This case suggests scar reactivation may trigger widespread blistering in pemphigus vulgaris patients.
Area of Science:
- Dermatology
- Autoimmune Diseases
- Immunology
Background:
- Pemphigus vulgaris is an autoimmune blistering disease.
- The Koebner phenomenon describes skin lesions appearing after trauma.
- An association between pemphigus vulgaris and Koebner phenomenon is uncommon.
Observation:
- A rare case of pemphigus vulgaris presenting over surgical scars is described.
- The autoimmune blistering disease manifested specifically within pre-existing surgical scar tissue.
Findings:
- Surgical scars can potentially trigger or exacerbate pemphigus vulgaris.
- Reactivation of pemphigus antigens within scars may induce a systemic autoimmune response.
- This localized scar reactivation led to generalized bullae formation on the trunk.
Implications:
- Highlights a rare but significant presentation of pemphigus vulgaris.
- Suggests surgical scars as a potential trigger site for pemphigus vulgaris flares.
- Emphasizes the importance of considering scar tissue in the pathogenesis of autoimmune skin disorders.

Skin 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.

Peptic Ulcer
Peptic ulcers are erosive lesions of the gastric or duodenal lining, most commonly caused by Helicobacter pylori infection. This Gram-negative, helical bacterium has adapted to survive the stomach’s acidic environment by producing urease, which converts urea into ammonia and carbon dioxide. The ammonia neutralizes gastric acid in the bacterium’s immediate environment, allowing colonization of the gastric mucosa. H. pylori attaches to mucus-secreting epithelial cells, penetrates the mucus...
Peptic Ulcer Disease III: Clinical Manifestations and Complications
Duodenal UlcersDuodenal ulcers are the most common form of peptic ulcer disease, presenting with chronic, intermittent epigastric pain. Pain typically appears 2–3 hours after meals, especially when the stomach is empty, often waking patients at night. It is characteristically relieved by food or antacids (“pain–food–relief”). Some patients remain asymptomatic until complications like bleeding or perforation emerge, particularly with NSAID or anticoagulant use.Gastric UlcersGastric ulcers share...
Pigmentation
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Peptic Ulcer Disease I: Introduction
Peptic Ulcer Disease (PUD) is characterized by mucosal excavation in the esophagus, stomach, pylorus, or duodenum. It can manifest as acute or chronic based on the extent and duration of mucosal involvement.
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...

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...
