Resumen
Los melanomas, cánceres de los melanocitos, son diversos con diferentes riesgos y pronósticos. Los melanomas mucosos, aunque raros, muestran un comportamiento agresivo y las tasas de supervivencia más bajas.
Área de la Ciencia:
- En el campo de la oncología
- Dermatología
- Patología
Sus antecedentes:
- El melanoma se origina en los melanocitos que se encuentran en la piel, los ojos y las membranas mucosas.
- Los melanomas son un grupo heterogéneo de neoplasias a pesar de un origen celular común.
- Comprender la diversidad del melanoma es crucial para un diagnóstico y tratamiento efectivos.
Objetivo del estudio:
- Proporcionar una revisión exhaustiva de los conocimientos actuales sobre varios tipos de melanoma.
- Analizar la evidencia existente sobre la genética del melanoma, los factores de riesgo, la epidemiología y el pronóstico.
- Para resaltar las características distintas y los resultados de los diferentes subtipos de melanoma.
Principales métodos:
- Revisión narrativa de la literatura científica existente.
- Análisis de los datos sobre la incidencia, la demografía y la presentación clínica del melanoma.
- Evaluación comparativa de los perfiles genéticos, los factores de riesgo y las tasas de supervivencia entre los tipos de melanoma.
Principales resultados:
- Los melanomas exhiben una heterogeneidad significativa en la genética, los factores de riesgo y la epidemiología.
- Los melanomas cutáneos son los más comunes, seguidos de los oculares y los acrales.
- Los melanomas mucosos, a menudo multifocales y amelanoticos, se asocian con las tasas de supervivencia más bajas.
Conclusiones:
- La clasificación del melanoma debe tener en cuenta sus diversos orígenes y presentaciones.
- Los melanomas mucosos representan un subtipo distinto y agresivo que requiere atención clínica específica.
- Se requiere una mayor investigación sobre la biología única de los melanomas de la mucosa para mejorar los resultados de los pacientes.

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.

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.

Changes in Skin Color: Clinical Perspectives
2.2K
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...

Pigmentation
2.6K
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...
