Papillary Dermis01:11

Papillary Dermis

4.0K
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

4.4K
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...

Desmosomes01:05

Desmosomes

5.9K
The term desmosome derives from the Greek words "desmo" and "soma" meaning "adhesion bodies." This structure was first observed during the late 1800s and described as small, dense nodules in the epidermis. Desmosomes are button-like structures that help form an interlinked network of intermediate filaments across the cells. These junctions are  essential to hold cells together under mechanical stress and to maintain tissue integrity. Desmosomes are multi-protein...

Skin Cancer01:30

Skin Cancer

4.8K
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...

Accessory Structures of the Skin: Sebaceous Glands01:21

Accessory Structures of the Skin: Sebaceous Glands

2.6K
A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

Classification of Epithelial Tissues: Stratified Epithelium01:29

Classification of Epithelial Tissues: Stratified Epithelium

10.7K
Stratified epithelium consists of several stacked layers of cells. They provide the durability to withstand constant physical and chemical attacks. Stratified epithelium is named after the shape of the most apical layer of cells. Stratified squamous epithelium is the most common type found in the human body. In this tissue, the apical cells are squamous, whereas the basal layer contains either columnar or cuboidal cells. The basal cells divide to form new daughter cells, which gradually become...

Area of Science:

  • Dermatology
  • Cutaneous Medicine

Background:

  • Papulosquamous diseases are common skin disorders.
  • Lesions can manifest as papules and plaques, sometimes in annular configurations.

Purpose of the Study:

  • To review common papulosquamous diseases that present with annular lesions.
  • To discuss the presentation and differential diagnoses of these conditions.

Main Methods:

  • Literature review of common papulosquamous diseases.
  • Analysis of disease presentations, focusing on annular forms.
  • Identification of differential diagnoses for each condition.

Main Results:

  • Common papulosquamous diseases with annular presentations include psoriasis vulgaris, pityriasis rosea, subcorneal pustular dermatosis, contact dermatitis, seborrheic dermatitis, and nummular dermatitis.
  • Specific disorders like pityriasis rosea and subcorneal pustular dermatosis characteristically appear annular.
  • Other conditions such as psoriasis vulgaris, seborrheic dermatitis, and nummular dermatitis can develop or progress to annular forms.

Conclusions:

  • Understanding the varied presentations of papulosquamous diseases is crucial for accurate diagnosis.
  • Recognition of annular lesions in these conditions aids in differentiating from other dermatoses.
  • This review provides a guide to the presentation and differential diagnosis of common papulosquamous diseases with annular lesions.
