DERMATOLOGIC SURGERY: ROTATION ADVANCEMENT FLAP AS FIRST LINE TREATMENT FOR HIGH-RISK SQUAMOUS CELL CARCINOMAS OF THE PERIOCULAR/PERIORBITAL ZONE- PRESENTATION AND DISCUSSION ABOUT 2 NEW CASES.

Rotation advancement flaps are a challenge for dermatosurgery and in particular the severe clinical cases, mainly affecting skin tumors in the facial area or the so-called ˝high risk areas˝. The proximity of these areas to important vital structures (such as nerves and blood vessels) also determines the need for more precision when performing this type of manipulation. Teamwork and preoperative planning are crucial and provide a number of advantages in terms of the timely achievement of the therapeutic endpoints.

KARAPANDZIC FLAP FOR SQUAMOUS CELL CARCINOMA OF THE LOWER LIPP: POTENTIAL ROLE OF NITROSAMINES IN EPROSARTAN AS CANCER TRIGGERING FACTORS.

Chronic alcohol use, smoking, poor dental hygiene, absorbed sun radiation over the years, fair skin (Fitzpatrick type 1), light eyes, painful sunburns, congenital or acquired immunosuppression, certain rare syndromes, as well as infections with human papillomaviruses are perceived as risk factors for the development of squamous cell carcinoma of the lips. The new and at the same time modern aspects involving the pathogenesis of keratinocyte tumors in practice prove to be quite problematic for both patients and clinicians. These aspects are involved in the contamination or increased availability of certain nitrosamines in the antihypertensive medications.
