Patients evaluated for venous disease may have other pathologic conditions contributing to symptomatology.
Of the more than 200 patients recently evaluated for venous disease, 8 were diagnosed with lower extremity masses. Three patients were referred for superficial phlebitis and four for deep venous obstructive disease. The eighth mass was found during work-up for varicose veins. Five masses were identified by palpation, and three were identified by duplex scan. All were confirmed by magnetic resonance imaging (MRI) or computed tomography (CT). Of the eight masses, three were malignant: a metastatic melanoma, a histiocytoma, and a myxoid liposarcoma. Nonmalignant masses included a hematoma, an inflammatory lesion, a hemangioma, and an intramuscular lipoma. One patient presented with deep venous thrombosis secondary to an occluded popliteal artery aneurysm compressing the popliteal vein. Thus, patients presenting with ostensible venous disease may have other pathologic conditions responsible for symptomatology. Careful physical examination will reveal a mass in a majority of patients who have one. Duplex scanning will identify masses that should be confirmed by MRI or CT. Definitive diagnosis should be made by biopsy, due to the high possibility of malignancy.
