Mass on dorsal metacarpals

Credit: Mark Hughes BVSc, MRCVS, Medivet, St Ives

3 x 3cm mass overlying the dorsal metacarpals on an English Springer Spaniel with plans to excise marginally with concurrent amputation of the lateral digit.

Two expanders, one v26-27 and one v26-22, were placed proximal to the mass via a lateral incision proximal to the carpus. Blunt dissection of the subcutaneous tissue was used to create the pockets.

The wounds were closed with a two-layer closure and stay/ quilting sutures used to prevent proximal movement of the expanders.

The expanders were left in place for 14 days. The mass was then excised, and the expanded skin used to close the resulting defect.

Mass on dorsal tibia

2 x 2cm mass overlying the dorsal tibia of a Staffordshire Bull Terrier, with plans to excise with 1.5cm margins.

4 v45-27 expanders were placed into a subcutaneous pocket proximal to the mass and margins via an incision over the medial stifle and two v26-22 expanders were placed distal to the mass and margins via an incision over the medial tarsus. Blunt dissection of the subcutaneous tissue was used to create the pockets.

The wounds were closed with a two-layer closure and stay/ quilting sutures used to prevent encroachment of the expanders inside the proposed margins.

The expanders were left in place for 14 days. The mass was then excised, and the expanded skin used to close the resulting defect.

Scar revision in maxillary region

3 cm scar from incomplete excision of neoplastic mass with plans to excise with 1cm margins.

Two v26-27 expanders were placed over the bridge of the nose via a caudal incision and one v45-27 expander was placed lateral to the scar via an incision at the lateral margin. Blunt dissection of the subcutaneous tissue was used to create the pockets.

The wounds were closed with a two-layer closure and stay/ quilting sutures used to prevent caudal migration of the expanders.

The expanders were left in place for 14 days. The mass was then excised, and the expanded skin used to close the resulting defect.

Mass on head

0.5 x 0.5cm mass on the head of a Boxer lateral to the midline, with plans to excise with 2cm margins and avoid distorting the eyelid.

Two v45-27 expanders were placed lateral to the mass and proposed margins on each side via a caudal incision. Blunt dissection of the subcutaneous tissue was used to create the pockets.

The wounds were closed with a two-layer closure and stay/ quilting sutures used to prevent encroachment of the expanders inside the proposed margins.

The expanders were left in place for 14 days. The mass was then excised, and the expanded skin used to close the resulting defect.

The mass was excised with the proposed 2cm margins and the expanders removed through the incision. The scar tissue from the implantation surgery was debrided.

The resulting defect was then closed using the expanded tissue.

Mass on lateral antebrachium

5 x 5cm mass on the lateral antebrachium of a Border Collie with plans to excise marginally. 4 v45-27 expanders were placed into a subcutaneous pocket proximal to the mass via a caudal incision proximal to the elbow and one v45-27 expander was placed distal to the mass via a caudal incision midway between the carpus and elbow. Blunt dissection of the subcutaneous tissue was used to create the pockets.

The wounds were closed with a two-layer closure.

The expanders were left in place for 14 days. The mass was then excised, and the expanded skin used to close the resulting defect.

Mass on shoulder

10 x 10cm mass over lateral shoulder with plans to excise with 2cm margins.

4 v45-27 expanders were placed cranial to the mass and proposed margins via and proximal incision and 4 v45-27 expanders were placed caudally via the same incision. Blunt dissection of the subcutaneous tissue was used to create the pockets.

The wounds were closed with a two-layer closure and stay/ quilting sutures used to prevent encroachment of the expanders inside the proposed margins.

The expanders were left in place for 14 days. The mass was then excised, and the expanded skin used to close the resulting defect.

Mass on lateral thigh

3 x 3cm mass on the lateral thigh of a Pug, with plans to excise with 2cm margins.

Three v45-27 expanders were placed into a subcutaneous pocket cranial to the mass and margins via a proximal incision and three v45-27 expanders were placed caudal to the mass and margins via the same incision. Blunt dissection of the subcutaneous tissue was used to create the pockets.

The wounds were closed with a two-layer closure and stay/ quilting sutures used to prevent encroachment of the expanders inside the proposed margins.

The expanders were left in place for 14 days. The mass was then excised, and the expanded skin used to close the resulting defect.

Mass on lateral tibia

3 x 3cm mass over lateral tibia with plans to excise with 2cm margins.

4 v45-27 expanders were placed proximal to the mass and proposed margins via and proximal incision and 3 v45-27 expanders were placed distally via a separate incision. Blunt dissection of the subcutaneous tissue was used to create the pockets.

The wounds were closed with a two-layer closure and stay/ quilting sutures used to prevent encroachment of the expanders inside the proposed margins.

The expanders were left in place for 14 days. The mass was then excised, and the expanded skin used to close the resulting defect.
