Resumen

La melanonicia longitudinal en niños, a menudo por nevi de la matriz de las uñas, generalmente se resuelve con el tiempo. Un caso destaca puntos pigmentados persistentes en la cutícula después de que la condición de la uña se desvaneció, ayudando al diagnóstico.

Área de la Ciencia:

Dermatología Pediátrica.
Trastornos de las uñas Trastornos de las uñas
Dermatopatología y Dermatopatología.

Sus antecedentes:

La melanonia longitudinal en niños es un hallazgo común.
Con frecuencia se confunde con el melanoma, lo que lleva a la ansiedad y las derivaciones innecesarias del paciente.
Los nevi de la matriz de las uñas son la causa más común y suelen ser benignos.

Objetivo del estudio:

Para reportar un caso de melanonicía longitudinal en un paciente pediátrico.
Para describir el curso clínico y las características de diagnóstico.
Para diferenciar las condiciones benignas de las lesiones relacionadas.

Principales métodos:

Presentación del caso clínico.
Observación de la melanonia longitudinal y los puntos pigmentados asociados.
Evaluación de seguimiento después de la resolución del hallazgo primario.

Principales resultados:

Una niña de 4 años presentó melanonicia longitudinal en su segunda uña izquierda.
Se observaron puntos pigmentados en la cutícula junto con el hallazgo de la uña.
La melanonia longitudinal se desvaneció, pero los puntos pigmentados persistieron.

Conclusiones:

La melanonia longitudinal en los niños es típicamente benigna y se resuelve espontáneamente.
Los puntos pigmentados persistentes en la cutícula pueden ser una característica distintiva de las condiciones benignas.
Este caso subraya la importancia de una cuidadosa observación clínica en los trastornos pediátricos de las uñas.

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...

The Dot Product

The Dot Product

Measuring how one directional quantity affects another along a specific path involves comparing their orientation and strength. When two such quantities are represented using direction and amount, a numerical result is computed to show how much one acts along the path of the other. This result comes from a rule combining both inputs' horizontal and vertical parts and adding the results.This calculation gives a single value that grows larger when both inputs point in similar directions and...

Dot Product

Dot Product

The dot product is an essential concept in mathematics and physics.
In engineering, the dot product of any two vectors is the product of the magnitudes of the vectors and the cosine of the angle between them. It is denoted by a dot symbol between the two vectors.
Consider a vehicle pulling an object along the ground using a rope. If the rope makes an angle with the horizontal axis, the work done can be calculated using the dot product of the force applied and the object's displacement.
The dot...

Dot Product: Problem Solving

Dot Product: Problem Solving

The dot product is a powerful tool in problem-solving involving vectors, given that the dot product of two vectors is the product of their magnitudes and the cosine of the angle between them measured anti-clockwise. Solving problems involving the dot product requires understanding its properties and developing a step-by-step process to solve them. Here are the main steps to follow when solving any general problem involving the dot product:
Identify the problem: Start by reading the problem and...

Scalar Product (Dot Product)

Scalar Product (Dot Product)

The scalar multiplication of two vectors is known as the scalar or dot product. As the name indicates, the scalar product of two vectors results in a number, that is, a scalar quantity. Scalar products are used to define work and energy relations. For example, the work that a force (a vector) performs on an object while causing its displacement (a vector) is defined as a scalar product of the force vector with the displacement vector.
The scalar product of two vectors is obtained by multiplying...

Light as Energy

The energy required to carry out photosynthesis is light— typically electromagnetic radiation from the sun. The range of all possible wavelengths is known as the electromagnetic spectrum.
Photons
A photon is a discrete electromagnetic particle or bundle of energy. Photons are characterized by their frequency, wavelength, and amplitude, similar to the properties of a wave. Waves with higher frequencies transmit more energy and have shorter wavelengths than longer wavelengths that transmit...
