“…Within both veterinary and human literature, the author was unable to find any reports of a separate neoplastic organ invading the tissues of the ureter, though some papers alluded to the possibility in humans 14 . In most cases where hydronephrosis was found secondary to a separate abdominal mass, it was due to compression of the ureter by the mass itself or associated fibrotic tissue 15–18 . Obstruction secondary to infiltrative disease was decided in this case with the appearance of the mass entering the ureter and extending distally into the UVJ where it was then visualized within the bladder.…”

Had the UVJ not been affected, compression from adjacent lymphadenopathy could not have been definitively ruled out without advanced imaging and/or necropsy.…”

A 3‐year‐old male neutered mixed breed dog was presented for chronic vomiting and diarrhea. Abdominal ultrasound revealed a large amorphous, heterogeneous mass within the left mid to caudal abdomen most consistent with medial iliac lymph node. It appeared to invade the left ureter and extend distally causing ureteral obstruction and hydronephrosis. Concurrent additional ultrasound findings were consistent with metastatic or multicentric neoplasia. Fine needle aspirates of the lymph node and spleen both confirmed large cell lymphoma. These findings present evidence of lymphoma invading directly from an organ into the ureter which has not previously been reported in dogs.

“…No existe un régimen único estándar para esta condición debido a su baja frecuencia y se debe usar quimioterapia sistémica, incluso si la diseminación más allá del ovario no es detectada durante la evaluación (2) . La mejor combinación debe adaptarse a la histología específica (9) . Aquellas pacientes con linfomas CD20 positivos podrían ser candidatas para el uso de rituximab combinado con otros fármacos; esta medicación puede ser bien tolerada y dar respuesta satisfactoria, como se observó en este caso (3) .…”

Aquel que se presenta como una masa pélvica con manifestación inicial es aun más raro. El diagnóstico impreciso o tardío se debe a menudo a las lesiones que se presentan similares al cáncer de ovario y puede conducir a un desenlace desfavorable. Presentamos el caso de mujer de 48 años con dolor abdominal. La ecografía y tomografía computada preoperatoria mostraron tumor quístico heterogéneo. La laparotomía reveló tumoración anexial izquierda de origen ovárico. Se realizó histerectomía total, ooforo-salpingectomía bilateral y omentectomía parcial. No se encontró evidencia de que la lesión se hubiese propagado más allá del ovario. El diagnóstico de linfoma no Hodking del tipo difuso de células B grandes difusas del ovario se realizó mediante examen histopatológico junto con inmunohistoquímica del tejido extirpado. El paciente recibió seis ciclos de quimioterapia. Después de 18 meses de seguimiento, la paciente continúa libre de enfermedad. Palabras clave. Linfoma ovárico primario, Tumor ovárico, Linfoma no Hodgkin.ABSTRACT Ovarian lymphomas are rare. Those presenting as a pelvic mass with initial manifestations are even rarer. Inaccurate or delayed diagnosis is often due to lesions resembling ovarian cancer and may lead to a poor outcome. We report the case of a 48-year-old female presenting with abdominal pain. Preoperative ultrasound and computed tomography showed a heterogeneous cystic mass. Laparotomy revealed a right adnexal mass of ovarian origin. Total hysterectomy, bilateral oophoro-salpingectomy, and partial omentectomy were performed. There was no evidence that the tumor had spread beyond the ovary. The diagnosis of primary nonHodgkin lymphoma of the ovary was done by histopathological examination along with immunohistochemistry of the excised tissue. The patient ...
