Skin Cancer01:30

Skin Cancer

4.7K
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...

Elastin is Responsible for Tissue Elasticity01:12

Elastin is Responsible for Tissue Elasticity

2.5K
Elastic fiber contains the protein elastin along with lesser amounts of other proteins and glycoproteins. The main property of elastin is that it will return to its original shape after being stretched or compressed. Elastic fibers are prominent in elastic tissues found in skin and the elastic ligaments of the vertebral column.
Ligaments and tendons are made of dense regular connective tissue, but in ligaments not all fibers are parallel. Dense regular elastic tissue contains elastin fibers and...

Changes in Skin Color: Clinical Perspectives

2.5K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Pigmentation01:19

Pigmentation

3.0K
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...

Papillary Dermis01:11

Papillary Dermis

3.9K
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...

Reticular Dermis01:15

Reticular Dermis

3.2K
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
  • Genetics
  • Ophthalmology
  • Cardiovascular Medicine

Background:

  • Pseudoxanthoma elasticum (PXE) is an ectopic mineralization disorder affecting skin, eyes, and arteries.
  • Characteristic skin changes are key diagnostic indicators.
  • Timely recognition of PXE is essential for managing extracutaneous manifestations.

Purpose of the Study:

  • To present a series of four cases of PXE.
  • To highlight the pathognomonic skin lesions associated with PXE.
  • To illustrate the diverse range of systemic complications in PXE.

Main Methods:

  • Clinical case series.
  • Dermatological examination for characteristic skin lesions.
  • Assessment of ophthalmological and cardiovascular status.

Main Results:

  • All four patients presented with pathognomonic skin lesions of PXE.
  • A broad spectrum of systemic complications was observed, including visual impairment and vascular abnormalities.
  • The findings underscore the multisystemic nature of PXE.

Conclusions:

  • PXE is a multisystem disorder with significant implications for skin, vision, and arterial health.
  • Prompt identification of cutaneous signs aids in the early detection of severe systemic complications.
  • This case series emphasizes the importance of a comprehensive evaluation in patients with suspected PXE.
