Health Education Index
Daniel Mark Siegel, M.D., Darren Keith Mollick, M.D., Anthony Wong, M.D., and the staff of LI Skin Cancer and Dermatologic Surgery have provided a health education resource for its patients and the Smithtown, New York community. We hope you find the skin care information here to be helpful.
- Mohs Surgery – Mohs micrographic surgery is a specialized procedure for the removal of skin cancer. It is a technique that allows dermatologists to selectively remove areas involved with the skin cancer, while at the same time preserving the greatest amount of normal tissue as is possible. Drs. Siegel, Mollick, and Wong are Fellows of the American College of Mohs Micrographic Surgery and Cutaneous Oncology. They are part of a very small number of specially trained dermatologists who perform this type of surgery in this region.
- Skin Cancer – 1 in 5 Americans will develop skin cancer in the course of their lifetimes. Basal cell carcinoma (BCC) is the most common form of skin cancer. Basal cell carcinoma and squamous cell carcinoma are the two major forms of "non-melanoma" skin cancer. The LI Skin Cancer and Dermatologic Surgery Library reviews skin cancer types and skin cancer treatment options, including medications (Aldara, 5-FU), excision, and Mohs Surgery. Learn more about skin cancer from the AAD, or visit the Skin Cancer Foundation for information regarding skin cancer prevention and support groups.
- Acne – Acne ("zits," "pimples") is a common skin condition affecting our teenage and adult patients. Daniel Mark Siegel, M.D., Darren Keith Mollick, M.D., and Anthony Wong, M.D. offer a review of acne skin care, acne myths, acne and diet, acne medications (retinoids, benzoyl peroxide), and other acne treatments. Learn more about acne from the AAD.
- Actinic Keratoses – Actinic keratoses, also referred to as "AKs," are a common pre-cancerous skin condition caused by excessive sun exposure. The Library offers reviews of AKs and the various treatments available, including cryotherapy and topical medications. Learn more about actinic keratoses from the AAD.
- Atopic Dermatitis – Learn more about eczema from the AAD or visit the National Eczema Association for information regarding dermatitis management and support groups.
- Psoriasis – Daniel Mark Siegel, M.D., Darren Keith Mollick, M.D., and Anthony Wong, M.D. offer reviews of the different types of this chronic skin disorder (plaque psoriasis, guttate psoriasis, and scalp psoriasis) and the psoriasis treatment options that are available, including corticosteroids, vitamin D derivatives, retinoids, phototherapy (PUVA), cyclosporine, and new biologic treatment options. Learn more about psoriasis from the AAD, or visit the National Psoriasis Foundation regarding psoriasis management and support groups.
- Sunscreens – The regular use of sunscreen is an important step to prevent sunburns, skin cancer and premature aging of the skin. Drs. Siegel, Mollick, and Wong review practical sunscreen information, including SPF values, types of ultraviolet radiation (UVA and UVB), sunscreen ingredients and tips on using sunscreen. Learn more about sunscreen.
The Library includes patient handouts and links to trusted health resources, such as the American Academy of Dermatology (AAD).
