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...

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,...

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...

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...

Papillary Dermis01:11

Papillary Dermis

5.8K
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...

Area of Science:

  • Dermatology
  • Inflammatory skin conditions
  • Clinical case reports

Background:

  • Prurigo pigmentosa (PP) is an inflammatory dermatosis characterized by unknown etiology.
  • Typical PP lesions manifest symmetrically on the trunk and neck, often accompanied by significant pruritus.
  • The condition's pathogenesis and typical presentation are well-documented in medical literature.

Observation:

  • A 13-year-old female presented with skin lesions consistent with prurigo pigmentosa.
  • The observed lesions displayed a distinct segmental arrangement along the left chest.
  • This pattern deviates from the commonly reported symmetrical distribution of PP.

Findings:

  • The case highlights an unusual segmental manifestation of prurigo pigmentosa.
  • This presentation challenges the established understanding of PP's typical distribution patterns.
  • The patient's lesions were clinically diagnosed as prurigo pigmentosa.

Implications:

  • This report expands the spectrum of clinical presentations for prurigo pigmentosa.
  • Further research may be warranted to explore potential genetic or developmental factors influencing PP distribution.
  • Clinicians should consider segmental patterns in the differential diagnosis of pruritic rashes resembling PP.
