Panel A. Photomicrograph is showing the luminal surface of the mass covered by partly denuded urothelium ((H&E stain at 200 power magnification). Panel B. At higher magnification the tumour comprised fascicles of bland spindle-shaped cells in a scanty hyaline stroma typical for a benign smooth muscle neoplasm ((H&E stain at 400 power magnification). Panel C. Histology of the lymph nodes showed multiple, coalescent, epithelioid granulomas with Langerhans' type giant cells and necrosis (H&E stain at 100 power magnification).
