Atypical Vascular Proliferation Secondary to Radiotherapy in a Patient With a History of Synovial Sarcoma.

We present the case of a 21-year-old male patient with a history of monophasic synovial sarcoma in his left thigh, which was treated with surgical resection, radiotherapy, and chemotherapy with mesna, doxorubicin, and Ifosfamide (MAI protocol). Approximately six years after the end of the oncological treatment, he presented a nodular, polypoid lesion in the left popliteal region, which was painless and fast growing. Ultimately, the biopsy was consistent with atypical vascular proliferation (AVP). Vascular lesions after radiotherapy include a wide spectrum of pathologies that range from benign lesions such as AVP to malignant ones with very poor prognosis such as angiosarcoma, the distinction between one and the other can be difficult, being the determination rearrangement or amplification of gene c-myc, a key to make an accurate diagnosis in case of doubt.

Tumor desmoplásico de célula pequeña y redonda paratesticular/testicular: reporte de caso y revisión de la literatura / Paratesticular/testicular desmoplastic round small cell malignant tumor: case report and literature review

Resumen El tumor desmoplásico de célula redonda y pequeña (TDCRP) es una patología neoplásica maligna agresiva y poco común. Afecta predominantemente a hombres entre la segunda y tercera década de la vida. Los pacientes que la padecen tienen un pronóstico pobre, con una supervivencia global a 5 años de hasta el 30%. Por lo general se presenta como una masa en la cavidad abdominal, frecuentemente multifocal. Para su tratamiento se recomienda un enfoque multimodal con cirugía, quimioterapia y radioterapia. Poco más de 20 casos de TDCRP a nivel testicular/paratesticular se han reportado en la literatura. A continuación, se presenta un caso ilustrativo en esta localización, se discute el caso y se realiza revisión de la literatura.

Abstract Desmoplastic small round cell tumor (DSRCT) is an aggressive and rare malignant neoplasm. It mainly affects young men in their twenties and thirties. Patients with it have a poor prognosis, with a 5-year survival rate of up to 30%. It generally presents as a mass in the abdominal cavity, often multifocal. A multimodal approach is recommended for its treatment, with surgery, chemotherapy, and radiotherapy. Just over 20 cases of testicular/paratesticular DSRCT have been reported in the literature. Below, we present an illustrative case in this location, we discuss the case and review the literature.

Síncope inducido por tos: no siempre es situacional / Cough-induced syncope: not always situational

Resumen El síncope representa un motivo de consulta relativamente frecuente en los servicios de urgencias. Se ilustra el caso de un hombre de 67 años que ingresó a urgencias con síncope secundario a bloqueo aurículo-ventricular de tercer grado, que se manifestó posterior a múltiples paroxismos de tos. Se discuten los diferentes mecanismos que explican esta relación poco común.

Abstract Syncope is a relatively common reason for consultation in emergency departments. The case is presented of a 67 year-old male who was admitted to the emergency department with syncope secondary to a third degree atrioventricular block, which subsequently presented with multiple paroxysms of cough. The different mechanisms that explain this rare combination are discussed.
