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...

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...

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 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...

Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

8.1K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

Jaundice01:25

Jaundice

35
Jaundice, or icterus, is the yellow discoloration of the skin, sclerae, and mucous membranes. It happens when plasma bilirubin levels rise above 2.5-3 mg/dL, leading to bilirubin deposition in tissue.Bilirubin is a byproduct of hemoglobin degradation. In macrophages, hemoglobin breaks down into globin and heme. Globin is converted into amino acids, while heme is turned into biliverdin by heme oxygenase, which is then reduced to unconjugated bilirubin by biliverdin reductase.Unconjugated...

Summary
This summary is machine-generated.

Tinea versicolor, a fungal infection caused by Malassezia, commonly presents as hypopigmented macules in dark-skinned individuals. Topical antifungals are effective, but recurrent cases may require oral or scheduled topical therapy.

Area of Science:

  • Dermatology
  • Mycology
  • Medical Microbiology

Background:

  • Tinea versicolor is a superficial fungal infection caused by the Malassezia genus.
  • It commonly affects individuals with darker skin tones, presenting unique clinical and histopathological features.
  • Understanding these specific characteristics is crucial for accurate diagnosis and effective management.

Purpose of the Study:

  • To review the key features of tinea versicolor, focusing on its epidemiology, clinical presentation, and histopathology in individuals with dark skin.
  • To highlight the diagnostic challenges and differential diagnoses relevant to this population.
  • To discuss current management strategies for tinea versicolor.

Main Methods:

  • Literature review of tinea versicolor, with a specific emphasis on studies involving dark-skinned individuals.
  • Analysis of clinical and histopathological findings reported in existing research.
  • Comparison of tinea versicolor presentation with other dermatological conditions.

Main Results:

  • Tinea versicolor in dark-skinned individuals often manifests as asymptomatic hypopigmented macules, though hyperpigmented lesions or a combination can occur.
  • Histopathological examination of affected dark skin reveals a thicker stratum corneum, increased tonofilaments in the granulosum, and more sequestered melanosomes.
  • Differential diagnoses include confluent and reticulated papillomatosis, seborrheic dermatitis, pityriasis rosea, pityriasis alba, and vitiligo.

Conclusions:

  • Tinea versicolor is a common fungal infection with distinct presentations in dark-skinned individuals.
  • Topical antifungal treatments are generally effective for management.
  • Recurrent or severe cases, particularly in immunocompromised patients, may necessitate systemic or prolonged topical therapies.
