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...

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...
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...
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...

Area of Science:

  • Dermatology
  • Medical Case Reports

Background:

  • Cutis verticis gyrata (CVG) is a condition of scalp skin hypertrophy.
  • It presents with characteristic brain-like convolutions.
  • CVG is classified into primary (essential, non-essential) and secondary forms.

Observation:

  • The primary essential form of CVG involves only scalp alterations.
  • The primary non-essential type is linked to neurological and ophthalmological issues.
  • Secondary CVG is more common and associated with other pathologies.

Findings:

  • This study presents a case of primary essential CVG in a male patient.
  • The patient was referred for surgical treatment of the scalp overgrowth.
  • Surgical resection is a key treatment for symptomatic CVG.

Implications:

  • Understanding CVG subtypes is crucial for diagnosis and management.
  • Surgical intervention can effectively treat the cosmetic and functional aspects of CVG.
  • This case contributes to the literature on primary essential CVG management.
