Bladder,posterior wall, endoscopic biopsy:
Fibrosis with chronic inflammation
The specimen consists of (1) five pieces of tissue fragments labeled as "superficial",measuring0.6*0.3*0.2cm in aggregate(cassette 1)and(2)two pieces of tissue fragments labeled as "deep",measuring0.4*0.3*0.2cm in aggregate(cassette 2)
Submitted in toto, one cassette.
Sections 1 show fibrotic stromal tissue infiltrated by lyphoplasmacytic cells,covered by fibrinous exduative deposition. Some stromal cells show bizzare and occasionally vacuolated nuclei,which are possibly chemotherapy-related reactive change.There is no evidence of epithelial dysplasia or malignancy.
Sections 2 also show fibrotic stromal tissue infiltrated by lyphoplasmacytic cells and histiocytic cells,which are positive for CD68
immunohistochemically. There is no evidence of malignancy.
