'Pseudosarcomatous' cells in urine cytology refer to reactive stromal cells or myofibroblasts that can mimic sarcoma, typically seen in conditions like post-operative spindle cell nodule, inflammatory pseudotumor, or radiation changes. These cells are spindle-shaped with elongated nuclei and may show mitotic activity, but they lack the marked atypia and pleomorphism of true sarcomas. They often occur after instrumentation, surgery, or in inflammatory conditions. Distinguishing them from sarcomatoid carcinoma or true sarcoma requires clinical correlation and sometimes immunohistochemistry (positive for vimentin, smooth muscle actin; negative for epithelial markers).
