Skin Cancer01:30

Skin Cancer

4.4K
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...

Changes in Skin Color: Clinical Perspectives

2.0K
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

2.5K
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

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

3.1K
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...

Summary

Disseminated hypopigmented keratoses (DHK) presents as a rare skin condition. Bedside investigations like potassium hydroxide (KOH) tests and dermatoscopy are crucial for accurate diagnosis and differentiating it from other dermatological disorders.

Area of Science:

  • Dermatology
  • Dermatopathology

Background:

  • Diffuse hypopigmented keratotic lesions can mimic various dermatological conditions, including pityriasis versicolor, stucco keratoses, and Darier's disease.
  • Accurate differentiation is essential for appropriate patient management.

Observation:

  • A novel entity, disseminated hypopigmented keratoses (DHK), presents as a differential diagnosis for these lesions.
  • The condition appears benign and slowly progressive, without associated systemic symptoms.

Findings:

  • Bedside investigations, specifically potassium hydroxide (KOH) wet mount and dermatoscopy, are highlighted as valuable tools.
  • These simple diagnostic methods aid in distinguishing DHK from other similar-appearing dermatoses.

Implications:

  • Emphasizes the importance of clinical and simple investigative tools in diagnosing rare dermatological conditions.
  • Highlights disseminated hypopigmented keratoses as a distinct entity requiring specific diagnostic considerations.
