Insights

Diagnosing bladder lymphoma through urine cytology is rare. This case highlights key cytomorphological features of diffuse large B-cell lymphoma in urine, emphasizing the need for immunohistochemistry.

Area of Science:

  • Uropathology
  • Cytopathology
  • Hematopathology

Background:

  • Lymphoma involvement of the urinary bladder is uncommon, often lacking typical genitourinary symptoms.
  • Cytologic findings of bladder lymphoma are infrequently reported in medical literature.

Observation:

  • A 77-year-old male presented with recurrent urinary tract infection and hematuria.
  • Bladder barbotage specimen revealed diffuse large B-cell lymphoma with immunoblastic morphology.

Findings:

  • Detailed cytomorphological features of lymphoma cells within the urine sediment were described.
  • Differential diagnoses for atypical cells in urine were discussed.

Implications:

  • This case underscores the diagnostic utility of urine cytology for detecting bladder lymphoma.
  • Correlating cytologic findings with immunohistochemical analysis is critical for accurate diagnosis and patient management.

Urinary Bladder01:23

Urinary Bladder

The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
Ureters01:22

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...

Urinary Tract Infection II: Pathophysiology

The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...

Anatomy of the Genitourinary System II: Bladder and Urethra

The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...

Urinary Tract Infection I: Introduction

Urinary tract infections (UTIs) impact various parts of the urinary system, including the kidneys, ureters, bladder, and urethra. These infections are generally bacterial, with Escherichia coli being the most common causative agent, often originating from the gastrointestinal tract. However, other bacteria, such as Staphylococcus saprophyticus, Klebsiella pneumoniae, and Proteus mirabilis, are also known to cause UTIs. The type, location, and underlying complexity of the UTI guide both...
