I have a lump near my elbow.ultra sound it was solid & it was being fed by blood, what could it be?

Usually benign: The most common solid lesions of the upper extremety are benign. If soft, consider a lipomatous growth. If firm benign fibromas can occur but one must think of MFH or a malignant fibrous tumor. The presence of blood supply is hard to define without angiography. If this has recently been noted and growing, then biopsy is indicated to determine method of management.
