Abstract:
Extramedullary and nonlymphoid organ involvement in chronic lymphocytic leukemia (CLL) is exceedingly rare, with only a few cases of bladder infiltration reported to date. Here, we present a case of a 71-year-old man with advanced-stage CLL who presented with gross hematuria initially thought to be secondary to a urinary tract infection. However, a cystoscopy with biopsy confirmed the diagnosis of extramedullary CLL with bladder involvement. The patient was started on venetoclax with improvement in symptoms and no recurrence of hematuria.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...
