Skin Cancer

6.7K
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.

Acne Infection

75
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

Papillary Dermis

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...

Changes in Skin Color: Clinical Perspectives

4.2K
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...

Area of Science:

  • Dermatology
  • Pathology
  • Clinical Medicine

Background:

  • Nevus comedonicus is a rare congenital follicular hamartoma.
  • It presents as closely grouped dilated follicular openings resembling comedones.
  • This condition can have associated syndromes and complications.

Purpose of the Study:

  • To report twelve previously undocumented cases of nevus comedonicus.
  • To describe the clinical features, atypical presentations, and complications.
  • To review associated syndromes and therapeutic interventions.

Main Methods:

  • Case series presentation.
  • Clinical diagnosis based on characteristic follicular openings and horny plugs.
  • Review of patient histories, clinical findings, and treatment outcomes.

Main Results:

  • Twelve new cases of nevus comedonicus were identified.
  • Diagnosis was confirmed by the presence of comedone-like follicular structures.
  • One case presented with nevus comedonicus syndrome; other cases showed atypical locations and complications.

Conclusions:

  • Nevus comedonicus exhibits diverse clinical manifestations.
  • Early diagnosis and management are crucial for addressing associated complications.
  • Further research into therapeutic options is warranted.
