Summary

Nested variant urothelial carcinoma is a challenging diagnosis due to its similarity to benign lesions. Early diagnosis and treatment are crucial as this cancer is as invasive as high-grade urothelial carcinoma.

Area of Science:

  • Uro-oncology
  • Pathology
  • Diagnostic challenges in bladder cancer

Background:

  • Nested variant urothelial carcinoma (NVUC) is a rare bladder cancer subtype.
  • Diagnosis is complicated by its resemblance to benign urothelial lesions like Von Brünn nest hyperplasia.

Observation:

  • Presents three clinical cases of NVUC.
  • Highlights the diagnostic difficulties encountered.

Findings:

  • Emphasizes the necessity of integrating clinical, cytological, histological, and immunohistochemical findings for accurate NVUC diagnosis.
  • Confirms NVUC's invasive nature, comparable to high-grade urothelial carcinoma.

Implications:

  • Underscores the importance of early and appropriate therapeutic management for NVUC.
