I strongly believe in sending nearly all specimens to the pathologist. Exceptions might be firbro-epithelial polyps and warts, although I sometimes send these off as well. Just yesterday a patient was telling me of a relative who has metastatic melanoma. She eveidently had some growths taken off a year ago, but the specimens were not sent off. Probably, they were nothing but it is always prudent to have the path report sitting in the patient's chart. Getting back to your situation. Most lipomas are easy to diagnose clinically (by looking at them at the time of surgery) or by the pathologist. However, there is something called a well differentialed liposarcoma. Sometimes these can be fairly benign looking and it takes the good eye of a crack pathologist to make the correct diagnosis. Some well differntiated liposarcomas can look fairly innocuous clinically and might fool an unsuspecting physician. For that reason I feel it is always wise to send the specimen off for examination. Lasers are an obliterative procedure and there is no specimen to send. You might ask, why not have my doctor, biopsy part and destroy the rest with laser ( or liposuction), the problem as I hinted, is that if it is a well differentiated liposarcoma, the physician might have biopsied only the "good" area of the tumor and missed the more serious portion.
