Resumen
Este estudio analizó 471 casos de pilomatrixoma, encontrando que es más común en adolescentes en la cara y el cuello. Las imágenes y la patología ayudan al diagnóstico, con la cirugía como el tratamiento principal para este tumor benigno de la piel.
Área de la Ciencia:
- Dermatología Dermatología dermatología.
- Patología Patología Patología.
- Radiología Radiología.
Sus antecedentes:
- El pilomatrixoma es un tumor benigno de apéndice de la piel.
- Comprender sus características clínicas, patológicas e imágenes es crucial para el diagnóstico y el manejo.
Objetivo del estudio:
- Para mejorar la comprensión de los médicos sobre el pilomatrixoma.
- Para analizar las características clínicas, patológicas y de imagen del pilomatrixoma.
Principales métodos:
- Análisis retrospectivo de 471 casos de pilomatrixoma.
- Incluir los datos de las evaluaciones clínicas, patológicas y por imágenes (ultrasonografía, TC, RM).
- Revisión de los resultados de la aspiración preoperatoria con aguja fina.
Principales resultados:
- El pilomatrixoma afecta predominantemente a las mujeres (52,4%) y ocurre con mayor frecuencia en niños de 0 a 10 años (46,5%).
- Las localizaciones más comunes son la cara (especialmente la región parótida) y el cuello.
- La histopatología revela células basaloides y de sombra; las imágenes muestran calcificaciones, patrones de eco específicos en el ultrasonido y hallazgos característicos en la TC y la RM.
Conclusiones:
- El pilomatrixoma es común en mujeres adolescentes, típicamente en la cara y el cuello.
- La citopatología y las imágenes proporcionan pistas de diagnóstico, mientras que la histopatología confirma el diagnóstico.
- La resección quirúrgica completa sigue siendo el tratamiento de elección.

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

381
Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

602
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

351
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
