JAMA
|February 20, 1978
Resumen
Las lesiones pigmentadas distintivas en familias propensas al melanoma indican un alto riesgo de la enfermedad. Este rasgo autosómico dominante ayuda en la detección temprana del melanoma e identifica a las personas en riesgo.
Área de la Ciencia:
- Dermatología Dermatología dermatología.
- Genética La genética.
- Oncología Oncología.
Sus antecedentes:
- El melanoma es una preocupación significativa para la salud, con agrupaciones familiares que sugieren una predisposición genética.
- La identificación de individuos con alto riesgo de melanoma es crucial para la detección temprana y la mejora de los resultados.
Objetivo del estudio:
- Para investigar un tipo distintivo de lesión pigmentada observada en familias propensas al melanoma.
- Para determinar el patrón de herencia y la importancia clínica de estas lesiones en la evaluación del riesgo de melanoma.
Principales métodos:
- Examen clínico e histológico de lesiones pigmentadas en siete familias propensas al melanoma.
- Análisis de la aparición de lesiones en pacientes con melanoma y sus familiares de primer grado.
- Evaluación de las lesiones como marcadores potenciales de melanoma hereditario.
Principales resultados:
- Las lesiones pigmentadas distintivas estaban presentes en el 90% de los pacientes con melanoma y en el 56% de sus parientes de primer grado.
- El reconocimiento de estas lesiones facilitó la detección temprana del melanoma en seis miembros de la familia.
- El síndrome demostró características de un rasgo autosómico dominante.
Conclusiones:
- El síndrome identificado, caracterizado por lesiones pigmentadas específicas, representa un rasgo autosómico dominante.
- Estas lesiones distintivas sirven como un valioso marcador cutáneo para identificar a las personas con alto riesgo de desarrollar melanoma.
- El reconocimiento temprano de este síndrome puede conducir a un diagnóstico e intervención oportunos para el melanoma.

Cancers Originate from Somatic Mutations in a Single Cell
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...
Cancer-Critical Genes I: Proto-oncogenes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

The Retinoblastoma Gene
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

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...

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...
