Osteoma osteoide: causa poco frecuente de dolor crónico en la muñeca en una niña / Osteoid osteoma: unusual cause of chronic pain in the wrist in a child

El osteoma osteoide es una lesión ósea benigna que, habitualmente, se acompaña de clínica típica caracterizada por dolor nocturno que mejora con antiinflamatorios no esteroideos. Aunque la presentación clínica es típica, con frecuencia, es común la demora diagnóstica, en especial, en los casos con localización atípica.Se presenta el caso de una paciente de 10 años con dolor en la muñeca izquierda de dos años de evolución con diagnóstico de osteoma osteoide localizado en el hueso grande del carpo. La localización atípica de la lesión conllevó un retraso diagnóstico importante

Osteoid osteoma is a benign bone lesion that is usually accompanied by a typical clinical condition characterized by night pain that improves with non-steroidal anti-inflammatory drugs. Although the clinical presentation is frequently typical, diagnostic delay is common, especially in cases with an atypical location.We report the case of a 10-year-old patient with left wrist pain of two years of evolution with diagnosis of osteoid osteoma located in capitate bone. The atypical location of the lesion led to a significant diagnostic delay.

Embolismos de cholesterol en el tracto urinario inferior como manifestación clínica de la enfermedad ateroembólica. Descripción de tres casos, uno de ellos simulando una neoplasia / Cholesterol embolism of the upper urinary tract as a clinical feature of atherosclerotic embolic vascular disease. Report of three cases, one of them simulating neoplasia

OBJETIVO: Presentar tres casos de enfermedadateroembólica con debut clínico en tracto urinarioinferior. Esta enfermedad es infrecuente, afectandosobre todo piel, riñón y músculo esquelético. Otrosórganos del tracto urinario son raramente afectados yde forma extraordinaria como debut de la enfermedad,sin afectación previa conocida de otras localizaciones.MÉTODOS/RESULTADOS: El primer paciente presentabaun episodio de hematuria asociado con una imagenecográfica y cistoscópica sospechosa de neoplasia.En los fragmentos de resección transuretral la lesióncorrespondía a una cistitis polipoide con algunas arteriasde pequeño tamaño ocupadas por agujas decolesterol, asociado con inflamación, ulceración y extravasación hemática. Al segundo paciente se le realizóuna cistoprostatectomía por un carcinoma urotelial,encontrándose incidentalmente numerosos émbolos decolesterol principalmente en lámina propia, pero tambiénen otras capas de la pared vesical, próstata, uretraen el verumontanum y una vesícula seminal, estasdos últimas localizaciones no descritas en publicacionesanteriores. En el tercer paciente el émbolo seencontró en un cilindro de biopsia prostática.CONCLUSIONES: Esta enfermedad poco frecuentepuede debutar como un proceso vesical o prostático yser diagnosticado por medio de biopsia de estos órganos.Puede simular una neoplasia vesical en ecografíao cistoscopia y debería ser incluida entre las entidadesrelacionadas o causantes de cistitis polipoide, un conocidosimulador de neoplasia

OBJECTIVES: To report three cases of ;;atherosclerotic embolic vascular disease with clinical ;;presentation in the lower urinary tract. This disease is not ;;frequent; it mainly affects the skin, kidneys and skeletal ;;muscle. Other organs of the urinary tract are rarely ;;affected and they are exceptionally the clinical site of ;;debut without previous known involvement of other ;;areas. METHODS/RESULTS: The first patient presented with ;;hematuria associated with an ultrasound/cystoscopical ;;image suspicion for neoplasia. Pathologic report of the ;;transurethral resection chips showed polypoid cystitis ;;with some small size arteries occupied by cholesterol ;;needles, associated with inflammation, ulcers and ;;hematic extravasation. The second patient underwent ;;cystoprostatectomy for a transitional cell carcinoma ;;and, incidentally, numerous cholesterol emboli were ;;found, mainly in the lamina propria, but also in other ;;layers of the bladder wall, prostate, urethra, veru ;;montanum, and one seminal vesicle; this two latter sites ;;have not being reported in previous publications. The ;;third patient showed the embolus within a prostate ;;biopsy core. ;;CONCLUSIONS: This unfrequent disease may present ;;as a bladder or prostatic process and be diagnosed by ;;biopsy of these organs. It may simulate a bladder neoplasia ;;on ultrasound or cystoscopy and should be included ;;among related or etiologic entities of polypoid cystitis, ;;a well-known simulator of neoplasia
