Papillary Dermis01:11

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...
Reticular Dermis01:15

Reticular Dermis

The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...
Skin Cancer01:30

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.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...
Skin Diseases and Disorders01:23

Skin Diseases and Disorders

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...
Acne Infection01:27

Acne Infection

Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
Accessory Structures of the Skin: Sebaceous Glands01:21

Accessory Structures of the Skin: Sebaceous Glands

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...

Area of Science:

  • Dermatology
  • Genetics
  • Dermatopathology

Background:

  • Acrokeratosis verruciformis of Hopf (AVH) is a rare genodermatosis.
  • It is characterized by multiple, skin-colored, flat-topped, hyperkeratotic papules.
  • AVH is distinct from keratosis follicularis, though sporadic cases exist.

Observation:

  • A 58-year-old woman presented with multiple hyperkeratotic papules on her hands and feet.
  • Lesions first appeared at age 13.
  • Her son also developed similar lesions around the same age, suggesting a hereditary pattern.

Findings:

  • The case presentation is consistent with acrokeratosis verruciformis of Hopf.
  • The familial occurrence supports the genodermatosis classification of AVH.
  • The distinct clinical presentation differentiates it from other hyperkeratotic conditions.

Implications:

  • Early diagnosis and understanding the genetic basis of AVH are crucial.
  • Management options for AVH include cryotherapy, keratolytics, laser ablation, topical retinoids, and systemic acitretin.
  • Further research into the specific genetic mutations and long-term outcomes of AVH is warranted.
