ABSTRACT

OBJECTIVES: The epidermoid cyst of the testis is a rare benign tumor. It accounts for approximately 1% of all testicular tumors. Generally, the testis has a palpable, painless mass with tumor markers (AFP, BHCG, and LDH) within normal ranges. Pathology reveals a cavity consisting of squamous epithelial cells containing keratin and non-nucleated keratic flakes in the absence of atypia or elements of teratoma. METHODS/RESULTS: We report the case of a young man who was diagnosed of epidermoid cyst after orchiectomy. CONCLUSIONS: Tumor enucleation would be a proper treatment when ultrasound studies suggest this diagnosis. However, we often perform orchiectomy due to a low rate of suspicion, non conclusive ultrasound studies, or due to the high percentage of malignant testicular tumors in this age range.

ABSTRACT

OBJECTIVE: This is a case of Encrusted Pyelitis (EP) caused by Corynebacterium urealyticum (CU) in a patient who had undergone a cystectomy and Bricker type urinary diversion 28 months beforehand. METHODS/RESULTS: After the immediate post-operative period no urinary catheterisation or any other urological procedure was performed on the patient. Before surgery, the patient presented non functional of the right kidney, secondary to a lithiasic obstructive uropathy. Clinical symptoms were deteriorated renal function, anuria, haematuria, pyrexia and left lumbar pain. It was suspected that the patient had this pathology and this was fundamental in diagnosis. Helicoid CT was the principal method used to show calcification plaques on the wall of the left renal pelvis, and selective culture of CU confirmed the diagnosis. Early commencement of treatment with vancomycin at an initial dosage of 500 mg/12 hours, and subsequent adjustment of dosage according to blood drug levels, achieved negative urine culture within a fortnight. Oral acidification was effected using acetohidroxamic acid 125 mg/12 hours, and it was continued until CT confirmed the disappearance or considerable reduction of the pyelic calcification plaques. CONCLUSION: The presence of EP in patients with urinary diversion is a matter worthy of consideration, even in patients who have not undergone recent urological procedures. Awareness of risk factors and early commencement of effective treatment may improve the prognosis of these patients.

ABSTRACT

OBJETIVO: Presentamos un caso de pielitis incrustante (PI) ocasionada por Corynebacterium urealyticum (CU) sobre paciente cistectomizado hace 28 meses y al que se le realizó una derivación urinaria tipo Bricker. MÉTODO/RESULTADOS: Desde el postoperatorio inmediato, no había sido sometido a cateterismo urinario ni a ninguna otra manipulación urológica. El sujeto presentaba con anterioridad a la cirugía, anulación funcional del riñón derecho secundario a uropatía obstructiva litiásica. El deterioro de la función renal, anuria, hematuria, fiebre y dolor lumbar izquierdo fue la clínica de presentación. La sospecha de esta entidad fue primordial para su diagnóstico. La TC helicoidal fue el método principal para mostrar las placas de calcificación en la pared de la pelvis renal izquierda, siendo el cultivo selectivo para CU el método diagnóstico de confirmación. La instauración precoz de tratamiento con vancomicina a una dosis inicial de 500 mg/ 12 horas y ajustando posteriormente su dosificación según los niveles de fármaco en sangre, logró una negativización del urocultivo en 15 días. Se llevó a cabo acidificación oral con ácido acetohidroxámico a dosis de 125 mg/ 12 horas, y se mantuvo su administración hasta la constatación mediante TC de la desaparición o reducción considerable de las placas de calcificación piélicas. CONCLUSIÓN: La existencia de PI en pacientes portadores de derivaciones urinarias es un hecho a tener en cuenta, incluso en aquellos pacientes que no han sufrido manipulaciones urológicas recientes. El conocimiento de los factores de riesgo y la instauración precoz de un tratamiento eficaz puede mejorar el pronóstico de estos sujetos (AU)
