Changes in Skin Color: Clinical Perspectives01:14

Changes in Skin Color: Clinical Perspectives

3.6K
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

3.8K
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...

Skin Diseases and Disorders

5.4K
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...

Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

2.4K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Skin Cancer01:30

Skin Cancer

5.2K
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...

Pleiotropy01:33

Pleiotropy

31.2K
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Area of Science:

  • Genetics
  • Dermatology
  • Oncology

Background:

  • Xeroderma Pigmentosum (XP) is an autosomal recessive disorder.
  • It involves defective DNA repair, leading to hypersensitivity to UV radiation and carcinogens.
  • Clinical features include severe photosensitivity, skin xerosis, poikiloderma, actinic keratosis, and a high risk of skin cancers.

Observation:

  • A rare case of XP in a 41-year-old male with dermatological, neurological, and ophthalmological involvement is presented.
  • Oral manifestations included severe pain and limited mouth opening due to perioral scarring.
  • Malignant tumors can occur on the lips, tongue, and buccal mucosa.

Findings:

  • XP patients exhibit intense cutaneous photosensitivity and develop malignant lesions in sun-exposed areas.
  • Oral implications in XP can be severe, impacting quality of life.
  • The condition necessitates ongoing dental care to monitor and manage oral lesions.

Implications:

  • Dental professionals play a vital role in the comprehensive management of Xeroderma Pigmentosum patients.
  • Regular dental follow-up is essential for early detection and treatment of oral manifestations.
  • This underscores the need for interdisciplinary collaboration in managing rare genetic disorders like XP.
