Tumor glómico causante de dolor de dedo crónico: la prueba de detección de isquemia es un signo clínico fiable para su diagnóstico. Informe de un caso y revisión de la literatura / Glomus tumor causing chronic finger pain: Ischemia test is a reliable clinical sign for the diagnosis. Case report and review of literature

Los tumores glómicos (TG) son neoplasias benignas raras, que se derivan de la estructura neuroarterial denominada cuerpo glómico, un shunt arteriovenoso especializado implicado en la regulación de la temperatura. Representan menos de 2% de los tumores del tejido blando, y entre 1 y 4,5% de los tumores de la mano. Aun cuando sus primeras descripciones aparecieron hace casi 100 años, son comunes la demora y la ausencia diagnósticas, las cuales originan un sufrimiento terrible. La tríada diagnóstica clásica consiste en dolor espontáneo, sensación de presión y sensibilidad, e hipersensibilidad al frío. La imagen de resonancia magnética (IRM) sigue siendo la modalidad de imagen más útil. La supresión del dolor tras inflar un esfigmomanómetro por encima de los niveles de la presión arterial sistólica (prueba de detección de isquemia) es altamente diagnóstica, por lo que sugerimos el uso rutinario de esta prueba simple en los casos de dolor en la extremidad superior de etiología desconocida. La resección quirúrgica es el tratamiento de elección, y es curativa. (AU)

Glomus tumors are a rare benign neoplasm arising from the neuroarterial structure called the glomus body, a specialized arteriovenous shunt involved in temperature regulation. They represent less than 2% of soft tissue tumors and between 1 and 4.5% of hand's tumors. Even though its first descriptions appeared almost 100 years ago, late and missed diagnoses are common, which leads to terrible suffering. The classic diagnostic triad consists of spontaneous pain, pressure sensation and tenderness, and cold hypersensitivity. Magnetic resonance imaging stills the most useful imaging modality. Abolition of pain after inflating a blood pressure cuff above systolic blood pressure levels (ischemia test) is highly diagnostic, so we suggest the routine use of this simple test in cases of upper limb pain of unknown etiology clear. Surgical excision is the treatment of choice and is curative. (AU)

Glomus tumor causing chronic finger pain: ischemia test is a reliable clinical sign for the diagnosis. Case report and review of literature.

Glomus tumors are a rare, benign neoplasm arising from the neuroarterial structure known as the glomus body, which is a specialized arteriovenous shunt involved in temperature regulation. They account for less than 2% of soft tissue tumors and between 1% and 4.5% of tumors in the hand.. Despite their first descriptions appearing almost 100 years ago, late and missed diagnoses are common, leading to significant suffering. The classic diagnostic triad includes spontaneous pain, a sensation of pressure and tenderness, and cold hypersensitivity. Magnetic resonance imaging remains the most useful imaging modality. The abolition of pain after inflating a blood pressure cuff above the systolic blood pressure level (ischemia test) is highly diagnostic.Therefore, we suggest the routine use of this simple test in cases of upper limb pain of unclear etiology . Surgical excision is the treatment of choice and is curative.
