Skin Cancer01:30

Skin Cancer

6.1K
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.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Papillary Dermis

6.0K
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...

Skin Diseases and Disorders

5.7K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Pigmentation01:19

Pigmentation

4.5K
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: Introduction01:30

Peptic Ulcer Disease I: Introduction

900
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...

Summary
This summary is machine-generated.

Lichen planus pemphigoides (LPP), a rare blistering disease, can present unusually on the vulva. Microscopic analysis is crucial for differentiating LPP from similar vulvar conditions.

Area of Science:

  • Dermatology
  • Autoimmune Blistering Diseases
  • Gynecologic Dermatology

Background:

  • Lichen planus pemphigoides (LPP) is a rare autoimmune blistering disease merging features of lichen planus and bullous pemphigoid.
  • LPP typically affects extremities and oral mucosa, but vulvar presentation is uncommon.

Observation:

  • This report details a case of vulvar LPP in an 80-year-old woman, initially misdiagnosed as lichen sclerosus.
  • The patient's vulvar LPP mimicked other conditions like erosive vulvar lichen planus and mucous membrane pemphigoid.

Findings:

  • Histologic and direct immunofluorescence studies are essential for accurate LPP diagnosis.
  • The case highlights diagnostic challenges due to overlapping clinical features with other vulvar dermatoses.

Implications:

  • Accurate diagnosis of vulvar LPP is critical for appropriate therapeutic selection.
  • This case underscores the importance of considering rare diagnoses and utilizing specialized diagnostic techniques in vulvar dermatology.
