Insights

A rare case of ureteral non-Hodgkin lymphoma (NHL) was initially misdiagnosed as transitional cell carcinoma. This large B-cell lymphoma was successfully treated with chemotherapy, with the patient remaining disease-free for 15 months.

Area of Science:

  • Urology
  • Oncology
  • Pathology

Background:

  • Ureteral tumors are rare, with transitional cell carcinoma being the most common malignancy.
  • Accurate diagnosis is crucial for appropriate treatment and patient outcomes.

Observation:

  • A 58-year-old man presented with right hydronephrosis, revealing a ureteral mass on imaging.
  • Initial urine cytology suggested transitional cell carcinoma, leading to nephro-ureterectomy and partial cystectomy.
  • Histopathology confirmed non-Hodgkin lymphoma (large B-cell type) of the ureter, classified as Clinical Stage IE.

Findings:

  • The patient received one course of systemic chemotherapy (THP-cop) but experienced severe thrombocytopenia.
  • Despite treatment limitations, no recurrence was observed 15 months post-operation.

Implications:

  • This case highlights the importance of thorough histopathological examination to differentiate ureteral malignancies.
  • Non-Hodgkin lymphoma of the ureter, though rare, can be managed effectively, even with treatment complications.
  • Further research into optimal chemotherapy regimens for ureteral lymphoma is warranted.

Ureters

The ureters are retroperitoneal tubes located on either side of the vertebral column. They are responsible for transporting urine from each kidney to the urinary bladder. These tubes have thick walls and are approximately 25-30 cm long. Their diameter is around 10 mm at the renal pelvis, gradually narrowing to 1 mm as the ureter obliquely enters the posterior bladder wall through the ureteric orifices. The shape of these orifices is slit-like, which helps to prevent urine backflow toward the...

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
