Can anyone explain what does it mean of spindle cell tumor? Considered as benign fibroushistiocytoma versus dermathofibrosarcoma protuberans. This is the pathology report last six months ago from the mass remove from my husband left leg. Is this risky? Regarding xray he seen always before nodule on his right lower lobe and to his present xray report hazy infiltrates in both lungs and still constant in smoking, can you give me advise what can do to convince to stop smoking. Thanks for acknowledging my questions.
