Tipo de artículo: Imagen clínica (Descripción) Imagen clínica y ecográfica correspondiente a celulitis disecante del cuero cabelludo en un paciente masculino adulto.Figura 1A: placa alopécica nodular de aproximadamente 15 mm de diámetro en la región temporal derecha, asociada a múltiples áreas alopécicas en la región occipital, compatibles con alopecia cicatricial inflamatoria.Figura 1B: ecografía cutánea de alta resolución (tricoecografía, escala de grises, corte transversal) que muestra trayectos sinuosos intradérmicos irregulares y estructuras hipoecoicas que alcanzan la hipodermis, configurando un patrón ecográfico no descrito previamente, denominado “signo de pintura rupestre”, por su similitud morfológica con representaciones rupestres prehistóricas.Este hallazgo ecográfico aporta valor diagnóstico precoz y puede evitar procedimientos invasivos como la biopsia cutánea.El paciente otorgó consentimiento informado por escrito para la publicación de la imagen, garantizando su anonimato y confidencialidad.Imagen de fuente propia, utilizada con fines científicos y docentes.
Article type: Clinical image (description) Clinical and ultrasonographic image corresponding to dissecting cellulitis of the scalp in an adult male patient.Figure 1A: nodular alopecic plaque measuring approximately 15 mm in diameter located in the right temporal region, associated with multiple alopecic areas in the occipital region, consistent with inflammatory cicatricial alopecia.Figure 1B: high-resolution cutaneous ultrasound (trichoultrasound, grayscale, transverse section) showing irregular intradermal sinus-like tracts and hypoechoic structures extending to the hypodermis, configuring a previously undescribed ultrasonographic pattern, referred to as the “cave painting sign”, due to its morphological resemblance to prehistoric cave paintings.This ultrasonographic finding provides early diagnostic value and may help to avoid invasive procedures such as skin biopsy.Written informed consent was obtained from the patient for the publication of the image, ensuring anonymity and confidentiality at all times.Image from own source, used for scientific and educational purposes.
