[Association of a melanoma and a spinocellular epithelioma on a burn scar of the scalp].

A thirty-nine-year-old caucasian man presented with an ulceration of the scalp, developing on an alopecia. The scalp indeed had been burnt by boiling water when the boy was two. During childhood and youth microtraumatisms induced superficial wounds which always healed easily. Nine months ago, a new ulceration followed a new trauma; the wound did not heal, and lay on a dark brown area. A biopsy diagnosed a malignant melanoma. The whole alopecic area was resected, under the ulceration and the pigmented area, as well as the external surface and the diploe. The defect was covered with a free transplant of omentum, revascularized by microsurgical anastomoses to the external carotid artery and the external jugular vein in the parotid bed. The omentum was immediately covered with split-thickness skin grafts. Histologic investigations demonstrated the association of a melanoma developing on a Hutchinson melanotic freckle and a squamous cell carcinoma.

[Results of great nerve trunk grafts].

The authors describe the results of 60 cases of trunk repairs, carried out by the same surgeon, and with a follow-up period of 18 months or more. The grafts were autologous and in most cases the donor was the saphenous nerve. The grafts were placed under microscope. The recipient sites were the median nerve (19 cases), the ulnar nerve (16 cases), the radial nerve (10 cases), the sciatic nerve (8 cases), the musculo-cutaneous nerve (6 cases) and the spinal nerves (1 case). After a description of the technique used, the results are analyzed in accordance with the classical criteria of Highet and Holmes, to which has been added the notion of harmony of movement. The overall evaluation has been carried out in accordance with the following scale: two-point discrimination less than 15 mm + M4 or M5 + harmony = very good; two-point discrimination impossible to interpret, protective sensitivity S2 + M4 or M5 + harmony - good; crude protective sensitivity (S1) + M3 or less X average. Of the 60 cases, 21 ranks as very good and 22 as good, together giving an aggregate 72% of the total, with 12 cases ranking as mediocre and 5 failures. The incidence on these results of the following factors in then considered: the patient's age, the nerve damaged, the level of the injury in a given nerve, the time intervening between the initial lesion and the repair, the length of the nerve injury, the number of fascicles, the quality of the tissues and the surgeon's experience. It would seem that the best chances of success involve: a patient aged under 30, a short intervening period (less than 6 months between accident and repair), an injury less than 5 cms long, the maximum number of fascicles, good quality tissues and an experienced surgeon.

[Breast reconstruction after mastectomy. Critical analysis of 240 cases].

A retrospective study on 240 cases of breast reconstruction was undertaken in order to make a critical analysis of the results of different techniques as silicone prosthesis, tissue expanders, and the myocutaneous flaps of latissimus dorsi and rectus abdominis. The authors discuss the indications, advantages, inconveniences and complications of each technique and point out the particular indications for each one, depending on the type of mastectomy performed and the quality of the remaining tissues. Good results can be obtained using prosthesis, or flaps, but the indications must be very criterious, as the number of complications may be high, and many operations might be needed to achieve a satisfactory result.

[Flat angioma. Therapeutical value of the laser].

Following a summary of the principles of quantum physics required to understand how lasers work, the main lasers used in therapeutics are described, together with their characteristics. Only the argon laser is used in the treatment of port wine stains. The selection of cases for laser treatment is based on such criteria as colour of the lesion, speed of recoloration and patient's age. Local complications are sometimes observed. The argon laser undoubtedly constitutes a progress in the treatment of port wine stains, a condition where surgery remains disappointing.
