Lumbar Wound from Liposarcoma Resection

Brielle Weinstein
, Julian Pribaz


The patient is a 59 year old female diagnosed with right lower back liposarcoma with positive margin after resection. She first noted the mass approximately one year prior to presentation to plastic surgery. The mass grew and initial excision was performed six months later. This had a positive deep muscular margin and she was then referred to a tertiary cancer care center. She completed radiation therapy prior to re-resection. In conjunction with the surgical oncology team, the patient presented to plastic surgery for resection of margin with reconstruction. She is otherwise healthy, non smoker, and active.


After tumor extirpation, the plastic surgery team was presented with defect 17 x 9.5cm defect through skin, subcutaneous tissue, fascia over lumbar region. The patient had extensive radiation changes to the surrounding skin and soft tissue [Figure 1].

Right lower back liposarcoma resection defect

Differential Diagnoses:

Pathology confirmed on presentation however prior to pathology differential diagnosis included lipoma, sarcoma

Workup Required:

 Patient did not require any specific imaging for plastic surgery portion of case


Local fascio-cutaneous flaps for vascularized soft tissue coverage

Expertise Needed:

Plastic Surgeon


After thorough evaluation, the defect was reconstructed with a double, extended V to Y advancement. The underlying tissues were attached to the paraspinal ligaments for approximation and closure of dead space. The lateral and interior extensions allowed the flap to recruit tissue from three directions. As with any complex defect, the team began with creation of a template. We prefer to do this with Duoderm (ConvaTec, Bridgewater, NJ) as it best replicates the motion of soft tissues. We then designed the flap with a double V to Y design [Figure 2]. The flap was then incised through skin, subcutaneous tissue and fascia to adequately mobilize [Figure 3 and Figure 4]. Two surgical drains were placed and the wound was closed in a multi layer fashion. The deepest tissues were approximated to paraspinal fascia, subcutaneous tissue and deep dermis approximated with 2-0 vicryl sutures and the skin approximated with 3-0 nylon [Figure 5].

Follow Up:

The patient has been seen in follow up at two weeks [Figure 6] for and two months [Figure 7] and is healing well. She has excellent truncal mobility.
