myxoid cystitis

Tuesday 4 May 2010

This peculiar form of cystitis, herein termed myxoid cystitis with "chordoid" lymphocytes, should be considered among the mimics of invasive urothelial carcinoma, especially those with a myxoid stroma.

Differential diagnosis

- Myxoid cystitis that closely mimicked myxoid urothelial carcinoma.

  • Invasive urothelial carcinoma is characterized by a number of histologic variants that can sometimes lead to diagnostic difficulty. In addition to those described by the World Health Organization, 2 additional variants have recently been described, invasive urothelial carcinoma with chordoid features and urothelial carcinoma with abundant myxoid stroma, both being characterized by the presence of a prominent myxoid stroma.
