Malignant tumors are relatively common on the dorsum of the hand. Excision of such lesions may result in a large defect not suitable for direct closure, and its reconstruction often represents a challenge for the hand surgeon. Several reconstructive techniques can be used to close this defect. We herein describe the application of a rotation flap for closure of a defect on the dorsum of the hand secondary to excision of a keratoacanthoma, and explain the principles and advantages of this technique.

W-plasty is a commonly used technique in facial cosmetic surgery to camouflage the straight line of a scar into a regularly irregular pattern. It consists of excising a series of consecutive small triangles of skin on each side of the scar, and imbricating the resultant triangular flaps, producing a "zig-zag" effect. This procedure is particularly useful on long, wide, curved, contracted, or anti-tension line scars of the forehead, cheeks, chin, and nose. We report the usefulness of this technique in an unaesthetic postsurgical facial scar.

Arterial pseudoaneurysm is a rare complication caused by damage to the arterial wall, resulting in a locally confined hematoma connected to the lumen of the artery. We report the case of a patient on anticoagulants who developed nodules at the surgical wound site after Mohs micrographic surgery for basal cell carcinoma. The initial clinical suspicion was the formation of a simple hematoma. However, Doppler ultrasound examination revealed the presence of pseudoaneurysms in the bilateral supratrochlear arteries. We believe this is the first reported case of supratrochlear artery pseudoaneurysm following dermatologic surgery.
