PREOPERATIVE DIAGNOSIS:,  Mass lesion, right upper extremity.,POSTOPERATIVE DIAGNOSIS: , Intramuscular lipoma, right arm, approximately 4 cm.,PROCEDURE PERFORMED:  ,Excision of intramuscular lipoma with flap closure by Dr. Y.,INDICATIONS FOR PROCEDURE:  ,This is a 77-year-old African-American female who presents as an outpatient to the General Surgical Service with a mass in the anterior aspect of the mid-biceps region of the right upper extremity.  The mass has been increasing in size and symptoms according to the patient.  The risks and benefits of the surgical excision were discussed.  The patient gave informed consent for surgical removal.,GROSS FINDINGS: , At the time of surgery, the patient was found to have intramuscular lipoma within the head of the biceps.  It was removed in its entirety and submitted to Pathology for appropriate analysis.,PROCEDURE: , The patient was taken to the operating room.  She was given intravenous sedation and the arm area was sterilely prepped and draped in the usual fashion.  Xylocaine was utilized as local anesthetic and a longitudinal incision was made in the axis of the extremity.  The skin and subcutaneous tissue were incised as well as the muscular fascia.  The fibers of the biceps were divided bluntly and retracted.  The lipoma was grasped with an Allis clamp and blunt and sharp dissection was utilized to remove the mass without inuring the underlying neurovascular structures.  The mass was submitted to Pathology.  Good hemostasis was seen.  The wound was irrigated and closed in layers.  The deep muscular fascia was reapproximated with #2-0 Vicryl suture.,The subcutaneous tissues were reapproximated with #3-0 Vicryl suture and the deep dermis was reapproximated with #3-0 Vicryl suture.  Re-approximated wound flaps without tension and the skin was closed with #4-0 undyed Vicryl in running subcuticular fashion.
