“…MRI can potentially characterize benign and malignant testicular lesions and can suggest a specific diagnostic hypothesis (e.g., Leydig cell tumor and seminoma) when specific imaging features are present [11]. However, MRI remains an expensive investigation tool and lacks availability [8,11,22].…”

Objective: The aim of our research was to evaluate the usefulness of real-time ultrasound elastography (RTE) in the differential diagnosis between benign and malignant non-palpable and palpable testicular lesions in children and adults. Methods: B-mode ultrasonography, color/power Doppler, and RTE of 54 patients with 54 unilateral testicular lesions were retrospectively investigated. The imaging results were supported by histopathological examination in all cases. On RTE, the value of tissue rigidity was reported in a chromatic scale and categorized into three patterns: Soft (red), medium (green), and hard (blue). Results: Among the 54 testicular lesions, 35 measured more than 2 cm in diameter (32 malignant and 3 benignant tumors) while 19 were <2 cm (9 malignant and 10 benignant lesions). In the group of the 41 proved malignant tumors, RTE demonstrated hard pattern in 32 cases. Immature teratomas exhibited a mixed pattern, likely related to their heterogeneous content. In the testicular lesion diagnosis, RTE showed a 78% sensitivity, an 85% specificity, a 94% positive predictive value, a 55% negative predictive value, and an 80% accuracy in differentiating malignant from benignant lesions. The integration of ultrasound (US) with color/power Doppler and RTE showed a diagnostic accuracy of 100% and 90%, respectively. Conclusion: Integrated with conventional US methods, RTE increases the diagnostic accuracy of US and color/power Doppler in the differential diagnosis between benignant and malignant testicular lesions.

“…Otra teoría propuesta es que se trate de una metaplasia escamosa del epitelio de los túbulos seminíferos o rete testis (7,12,15) . Los criterios histológicos para el diagnóstico de esta lesión siguen siendo, al día de hoy, los descritos por Price (16) En la pieza macroscópica se suele encontrar una lesión redondeada pequeña (1-3 cm) de color amarillo nacarado, con una cápsula fibrosa que puede presentar calcificaciones en grado variable. Su contenido puede variar en consistencia desde totalmente líquido hasta grumoso.…”

IntroducciónEl 95% de las masas intratesticulares son de naturaleza maligna, por lo que toda masa intratesticular será considerada maligna hasta que no se demuestre lo contrario y se tratará, por lo tanto, mediante orquiectomía radical (1)(2)(3)(4) . Los tumores malignos testiculares representan la neoplasia más prevalente en los varones entre los 15 y 35 años de edad. La evaluación de estos tumores incluye historia clínica, examen físico, marcadores tumorales y estudios de imagen escrotal como la resonancia magnética o la ecografía. Esta última presenta una sensibilidad cercana al 100% para detectar lesiones intratesticulares, por lo que en la actualidad sigue siendo el método de elección inicial para el estudio de la patología intraescrotal (5) .El quiste epidermoide testicular es un tumor benigno raro que representa aproximadamente el 1-2% de las neoplasias intratesticulares y suele presentar patrones ecográficos característicos (1)(2)(3)(4)(5)(6)(7) . Presentamos dos casos diagnosticados en nuestro hospital mediante ecografía preoperatoria y realizamos una revisión de la literatura actualizada sobre el tema. Presentación de los casos Caso 1Paciente varón de 21 años que desde hace más de un año nota un bulto, no doloroso en el testículo derecho.

“…Adenomatoid tumours are usually round and appear homogenously echogenic. 6 Adenomatoid tumours are usually small round/oval well circumscribed lesions less than 20mm, though according to the literature they range from 4mm to 50mm. 7 Most of the cases are single tumours near or in the poles of the epididymis, though other locations include the body of epididymis, the tunica vaginalis, tunica albuginea, rete testis, parietal tunica and spermatic cord.…”

Multiple adenomatoid tumours in the Epididymis and Tunica vaginalis: Case report

We describe the case of a 65 year-old male presenting with a tender right testicular mass, confirmed to be a tumour on ultrasound. The patient underwent a radical inguinal orchidectomy and histology revealed multiple adenomatoid tumours in epididymis and tunica vaginalis. This is an infrequent benign tumour of mesothelial origin that has rarely been reported as multiple lesions in the literature. Immunohistochemistry demonstrates that adenomatoid tumour and mesotheliomas share the expression of podoplanin (D2-40) which is helpful to differentiate them from carcinomas. On the other hand adenomatoid tumour is differentiated from mesothelioma on morphological grounds since the former does not exhibit cellular atypia, mitotic activity or bland focal tumour necrosis. Although testis preserving surgery can be an option for benign adenomatoid tumours, most patients (as in our case) proceed to orchidectomy as diagnosing them confidently can be difficult.
