Ultrasound diagnosis of three cases of Mondor's disease.

OBJECTIVE: To describe clinical features and ultrasound findings of three cases of a little-known and relatively infrequent entity in daily clinical activity, which is often unnoticed and under-reported: penile Mondor's disease or superficial penile veins thrombophlebitis. METHODS: We are reporting the cases of three patients aged 33, 25 and 39 years who were referred to our department, the first case with suspicion of inguinal hernia, the second one to rule out testicular pathology because of pubic and perineal discomfort, and the third one for painful induration of the dorsal region of the penis. The three patients underwent Doppler-ultrasound examination (Toshiba®, using a 13-18MHz linear transducer) to establish definitive diagnosis, and had a favorable evolution with conservative management. RESULTS: Ultrasound examination revealed: Case 1. Penile superficial dorsal vein and lateral superficial veins thrombosis. Case 2. Thrombosis of the right branch of the superficial dorsal vein and its perineal distal connections. Case 3. Penile superficial dorsal vein thrombosis. Definitive diagnosis of the three cases was Mondor's disease. CONCLUSIONS: Mondor's disease is an often under-reported entity in daily clinical activity. Doppler-ultrasound findings (echogenic material within veins, lack of any response after compression by the transducer and absence of color flow) confirm de diagnosis. This disease has a favorable evolution and functional prognosis. Knowledge of Mondor's disease by echographists is basic to avoid false-negative results in radiologic examination.

Diagnóstico ecográfico de tres caso de enfermedad de Mondor del pene / Ultrasound diagnosis of three cases of Mondor`s disease

OBJETIVO: Describir las características clínicas y los hallazgos ecográficos de tres casos de una entidad poco conocida y relativamente infrecuente en la actividad clínica diaria, lo que ocasiona que sea infradiagnosticada: la enfermedad de Mondor del pene o tromboflebitis aislada de las venas superficiales del pene. MÉTODOS: Los casos corresponden a pacientes de 33, 25 y 39 años remitidos el primero por sospecha de hernia inguinal, el segundo para descartar patología testicular por molestias púbicas y perineales, y el tercero por induración dolorosa del dorso del pene. Se realizó ecografía-Doppler color de alta resolución (Toshiba®, con transductor lineal de 13-18 MHz) y tras el diagnóstico se instauró tratamiento conservador, evolucionando los tres casos de forma favorable. RESULTADOS: En el estudio ecográfico se apreció: Caso 1. Trombosis de la vena dorsal superficial y venas laterales superficiales. Caso 2. Trombosis de la rama derecha de la vena dorsal superficial y de sus conexiones distales perineales. Caso 3. Trombosis de la vena superficial dorsal del pene. Los tres casos fueron diagnosticados como enfermedad de Mondor. CONCLUSIONES: La enfermedad de Mondor es una entidad frecuentemente infradiagnosticada en la práctica diaria. Los hallazgos ecográficos-Doppler (contenido ecogénico en el interior de la vena, falta de respuesta a la compresión y ausencia de flujo) son diagnósticos. Se trata de una entidad clínica con buena evolución y pronóstico funcional. Es fundamental el conocimiento de esta entidad por parte del ecografista para evitar falsos negativos en el estudio radiológico(AU)

Retroperitoneal cystic mature teratoma as the presenting clinical scenario of testicular carcinoma.

OBJECTIVE: To describe a case of retroperitoneal mature teratoma presenting as metastasis of a testicular mixed germ cell tumor in a thirty year old man who had lumbar and abdominal pain and mass sensation in the left hemiabdomen. METHODS: Abdominal ultrasound and thoracic-abdominal-pelvic CT multidetector scan were performed, and then after a Doppler ultrasound study of the testicles. Surgical treatment was performed: orchiectomy and retroperitoneal lesion resection. RESULTS: Imaging studies showed a big cystic lesion in the left retroperitoneal space, 13 × 12 × 11 cm, well defined, with thin septa, displacing the kidney; and a solid-cystic 4 cm left testicular tumor, with multiple septa, solid poles and arterial flows with low resistances. Thoracic extension study did not show any finding. The histopathologic results of the orchiectomy and retroperitoneal resection pieces were, respectively, testicular mixed germ cell tumor (seminoma, with intratubular seminoma foci and teratoma) and mature cystic teratoma. CONCLUSIONS: Germ cell tumors derive from multipotencial cells with a large capacity of differentiation, and the nodal paraaortic chains are a natural way of dissemination of these neoplasms. Because of that, in the presence of a retroperitoneal lesion in a young patient we have to rule out testicular tumor metastasis. The retroperitoneal mature cystic teratoma must be considered as a lesion with malignant potential.

Teratoma quístico maduro retroperitoneal como primera manifestación de carcinoma testicular. Estudio radiológico / Retroperitoneal cystic mature teratoma as the presenting clinical scenario of testicular carcinoma. Radiological study

OBJETIVO: Describir un caso de teratoma maduro retroperitoneal como metástasis de un tumor mixto de células germinales testicular en un paciente de 30 años que debutó con dolor lumbar, abdominal y sensación de masa en hemiabdomen izquierdo.MÉTODOS: Se realizó ecografía abdominal, TC multidetector tóraco-abdomino-pélvico, y ante los hallazgos apreciados ecografía-doppler testicular. Se practicó orquiectomía y resección de la lesión retroperitoneal. RESULTADOS: En las pruebas de imagen se apreció a nivel retroperitoneal izquierdo una gran lesión quística de 13x12x11 cm de diámetro, bien delimitada, con finos septos, que desplazaba el riñón; y una masa testicular de 4 cm, sólido-quística, multiseptada, con polos sólidos y flujos vasculares arteriales de baja resistencia. El estudio de extensión torácico no mostró hallazgos. Los resultados anatomopatológicos de las piezas de orquiectomía y de la lesión retroperitoneal fueron respectivamente: tumor mixto de células germinales (seminoma, con focos de seminoma intratubular y teratoma), y teratoma quístico maduro.CONCLUSIONES: Debido a que los tumores de células germinales derivan de células multipotenciales con gran capacidad de diferenciación y que las cadenas ganglionares paraaórticas constituyen una vía de diseminación natural de estas neoplasias, la presencia de una lesión retroperitoneal en un paciente joven, aún sin signos radiológicos de malignidad (en nuestro caso quística) obliga a descartar metástasis de tumor testicular. El teratoma maduro retroperitoneal postpuberal debe considerarse una lesión con potencial maligno(AU)
