A dermatologic surgery specialist, Dr. Grekin directs the Department's Dermatologic Surgery and Laser Center.

In the Surgery Center, Dr. Grekin treats a variety of skin disorders including certain kinds of skin cancer. He is a specialist in the use of Mohs Micrographic Surgery, a very precise technique for treating facial tumors. The practice involves excising the tumors and subsequently "mapping" the removed tissue to track the progress of the surgery; the aim is to remove only the cancerous tissue and leave all other skin tissue intact. While the procedure can be time consuming, it has a very high success rate.

In their search to develop non-destructive methods for treating skin disorders, dermatologists are increasingly turning to lasers and Dr. Grekin is no exception. An expert in laser surgery, he uses lasers to treat a variety of common disorders such as pigmented lesions and facial veins, as well as to remove warts and port-wine stains. Lasers offer several advantages over more traditional surgery: they are more precise, less destructive, and frequently result in faster healing of the skin than other techniques.

In his clinical research, Dr. Grekin capitalizes on the features of lasers. Presently, he is investigating the use of Ruby lasers to treat pre-cancerous lentigo maligna, a condition which can lead to melanoma. He is also studying how lasers might replace the use of chemical peels in the treatment of molluscum contagiosum, a skin disorder commonly found in children and in patients with suppressed immune systems.

Dr. Grekin also has extensive experience in cosmetologic dermatology. In the Surgery Center, he performs procedures such as liposuction, hair transplants, vein sclerosing, chemical peels, collagen injections, Gortex implants for facial creases and lip enhancements and Botox injections for facial wrinkles. In the Laser Center, he utilizes lasers to remove tattoos and treat a variety of skin anomalies. He is currently investigating the use of a relatively new laser to permanently remove unwanted body hair. Dr. Grekin is also involved in a clinical trial examining the use of an electrosurgical resurfacing device to diminsh wrinkles.

Dr. Grekin is a member of several professional societies including the American Medical Association, the American College of Mohs Micrographic Surgery and Cutaneous Surgery, and the American Society for Lasers in Medicine and Surgery.
