Skin Diseases and Disorders

4.7K
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

5.1K
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...

Pigmentation01:19

Pigmentation

3.7K
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...

Changes in Skin Color: Clinical Perspectives

2.9K
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...

Pleiotropy01:33

Pleiotropy

42.0K
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,...

Summary

Poikiloderma, a skin condition, can signal serious genetic disorders like Rothmund-Thomson syndrome. Early diagnosis of poikiloderma is crucial for managing these genodermatoses and preventing complications.

Area of Science:

  • Dermatology
  • Genetics
  • Pediatrics

Background:

  • Poikiloderma is a distinct skin condition characterized by atrophy, telangiectasia, and pigmentary changes.
  • It is frequently misdiagnosed as mottled pigmentation by non-specialists.
  • Poikiloderma is a significant early symptom in several rare genetic disorders (genodermatoses).

Purpose of the Study:

  • To review genodermatoses presenting with poikiloderma.
  • To aid clinicians in diagnosing and managing patients with poikiloderma.
  • To propose a diagnostic algorithm for early recognition.

Main Methods:

  • Literature review of genodermatoses associated with poikiloderma.
  • Analysis of clinical presentation and diagnostic criteria.
  • Development of a diagnostic algorithm.

Main Results:

  • Poikiloderma is a presenting sign for multiple genodermatoses including Rothmund-Thomson syndrome, dyskeratosis congenita, and Bloom syndrome.
  • These conditions often manifest in early childhood and may include photosensitivity and multi-organ involvement.
  • Poikiloderma typically precedes more severe systemic manifestations.

Conclusions:

  • Poikiloderma is a critical indicator of underlying genetic disorders.
  • Prompt diagnosis and management are essential to mitigate disease progression and complications.
  • The proposed algorithm facilitates early identification of at-risk patients.
