[Primary lymphoma of the bladder].

Area of Science:

• Urology
• Oncology
• Pathology

Background:

• Primary malignant lymphomas of the bladder wall are rare, unlike secondary involvement.
• Non-Hodgkin's lymphoma can exceptionally manifest as a primary bladder tumor.

Observation:

• Two cases of primary non-Hodgkin's malignant lymphoma of the bladder are presented.
• Clinical presentation includes varied and nonspecific urinary symptoms.
• Radiological and endoscopic appearances are indistinguishable from other bladder tumors.

Findings:

• Histological examination is essential for diagnosing primary bladder lymphoma.
• Pathophysiological hypotheses for bladder lymphoma are discussed.

Implications:

• Diagnosis relies heavily on histopathology due to non-specific clinical and imaging findings.
• Chemotherapy is the primary treatment modality.
• Endoscopic procedures may offer symptomatic relief in select cases.
