The use of a dermal substitute and thin skin grafts in the cure of "complex" leg ulcers.

Background: In some chronic leg ulcers, a reconstructive operation using skin grafts may be extremely difficult or is quite likely to fail as a result of the position, the width, and the depth of the lesions.

Objective: To evaluate the effectiveness of a dermal substitute and thin skin grafts in the treatment of patients suffering from deep and wide chronic leg ulcers.

Materials & Methods: Twenty-six consecutive patients with leg ulcers at least 1 year old were admitted to the study.

[Excisional biopsy with wire localisation of non-palpable breast lesions: indications and limitations].

Preoperative localisation of non-palpable breast lesions is necessary for excisional biopsies. This can be achieved with methods such as anchor wire, charcoal marking, or radio-guided localisation. The aim of the present study was to evaluate retrospectively our experience with the wire localisation technique.
