Skin Cancer

Skin Cancer

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

Changes in Skin Color: Clinical Perspectives

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...

Acne Infection

Acne Infection

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...

Skin Diseases and Disorders

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...

Pigmentation

Pigmentation

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...

Area of Science:

Dermatology
Photobiology

Background:

Sunlight exposure triggers diverse skin conditions (dermatoses).
Diagnosing these conditions is complex due to similar appearances, unclear terminology, and varied classifications.
Ultraviolet radiation is a primary factor in many skin reactions.

Purpose of the Study:

To review the modern classification and clinical features of photodermatoses.
To provide guidance on diagnosis and treatment of ultraviolet radiation-induced skin conditions.
To enhance diagnostic evaluation and treatment strategies for patients.

Main Methods:

Selective literature review over the past 20 years.
Description of current nosology, clinical presentations, and diagnostic approaches.
Emphasis on treatment and prevention strategies.

Main Results:

Photodermatoses result from abnormal reactions to sunlight, primarily its ultraviolet component.
Classified into phototoxic and photoallergic reactions (to known photosensitizers) and idiopathic types (unknown photosensitizer).
Prevalence varies significantly, from rare conditions like hydroa vacciniforme to common ones like polymorphic light eruption.

Conclusions:

Photodermatoses, while not life-threatening, can cause significant patient suffering.
Effective management requires both appropriate treatment and crucial preventive measures.
Accurate diagnosis and understanding of photodermatoses are key for patient care.
