The MRI findings, the intrathecal production of immu- noglobulins, and the excellent response to corticosteroid treatment in our patient support this hypothesis. Histologically, the skin lesions show perivascular lym- phocytic infiltration, proliferation of fibroblasts, and dense collagen deposition within the dermis, and—in contrast to plaque-morphea—the deeper connective tissues including muscle and bone structures may be involved in LSCS. The involvement of all structures including the brain underlying LSCS lesions in our patient is intriguing and suggests an ongoing inflammatory process.

Abnormal scars, such as hypertrophic scars and keloids, and cutaneous fibrosis that develops in diseases such as systemic sclerosis and graft-versus-host disease can be even more challenging for patients. There is a large body of literature suggesting that inflammation promotes the deposition of scar tissue by fibroblasts. Mast cells represent one inflammatory cell type in particular that has been implicated in skin scarring and fibrosis. Most published studies in this area support a pro-fibrotic role for mast cells in the skin, as many mast cell-derived mediators stimulate fibroblast activity and studies generally indicate higher numbers of mast cells and/or mast cell activation in scars and fibrotic skin.

  • Fundamentals of Dermatology Describing Rashes and Lesions
    Dermatology for the Non-Dermatologist May 30 – June 3, 2018 - 1 - Fundamentals of Dermatology Describing Rashes and Lesions History remains ESSENTIAL to establish diagnosis – duration, treatments, prior history of skin conditions, drug use, systemic illness, etc., etc. Historical characteristics of lesions and rashes are also key elements of the description. Painful vs. painless? Pruritic? Burning sensation? Key descriptive elements – 1- definition and morphology of the lesion, 2- location and the extent of the disease. DEFINITIONS: Atrophy: Thinning of the epidermis and/or dermis causing a shiny appearance or fine wrinkling and/or depression of the skin (common causes: steroids, sudden weight gain, “stretch marks”) Bulla: Circumscribed superficial collection of fluid below or within the epidermis > 5mm (if <5mm vesicle), may be formed by the coalescence of vesicles (blister) Burrow: A linear, “threadlike” elevation of the skin, typically a few millimeters long. (scabies) Comedo: A plugged sebaceous follicle, such as closed (whitehead) & open comedones (blackhead) in acne Crust: Dried residue of serum, blood or pus (scab) Cyst: A circumscribed, usually slightly compressible, round, walled lesion, below the epidermis, may be filled with fluid or semi-solid material (sebaceous cyst, cystic acne) Dermatitis: nonspecific term for inflammation of the skin (many possible causes); may be a specific condition, e.g. atopic dermatitis Eczema: a generic term for acute or chronic inflammatory conditions of the skin.

Lung Disease in Scleroderma -What the lungs do -What can go wrong – symptoms of lung disease 3. Kidney/Renal Disease in Scleroderma -What the kidneys do -What can go wrong This seventh chapter usually takes about 15 minutes. Chapter 7- 2 Remember: Many of the things discussed in this chapter are scary. No one with Scleroderma will have all or even most of the problems described in this manual. We want to include most of the problems that could develop in Scleroderma so that all patients will feel informed. It’s important to discuss your concerns with your doctor. Heart Disease in Scleroderma Who Develops Heart Disease Many people with Scleroderma do not develop heart disease. Some do. If there is a problem with the heart, the person with Scleroderma may be totally unaware of it at first. That's because there are usually no symptoms of heart disease in the early stages of Scleroderma. Doctors use tests to find out if the heart has been affected. What the Heart Does The heart pumps blood to the body and to the lungs The circulatory system is made up of 2 parts: 1. Circulation to the body (Systemic) This part sends blood to the body and oxygen to the organs 2. Circulation to the lungs - (Pulmonary) This part sends blood to the lungs to get oxygen. The heart has 4 chambers: - 2 upper chambers (atria).

  • Liquid Nitrogen Treatment Fact Sheet
    University of California, Berkeley 2222 Bancroft Way Berkeley, CA 94720 Appointments 510/642-2000 Online Appointment www.uhs.berkeley.edu LIQUID NITROGEN TREATMENT FACT SHEET Application of liquid nitrogen is often used to treat skin lesions such as warts, molluscum and keratoses. Although the exact mechanism of action is unclear, freezing damages the treated lesion preventing its survival. Treatment rarely requires anesthesia and almost never leaves a scar. What to expect f Liquid nitrogen is applied to the top of the skin lesion. Freezing occurs throughout the area which extends slightly to the surrounding tissue. Freezing can cause a stinging, burning pain that peaks about 2 minutes after the treatment is performed. f Within minutes after freezing, surrounding skin will become red and begin to swell. In most cases a blister will actually form within 3-6 hours. Often there is a small amount of bleeding into the blister which will turn it dark purple of black. This is expected and should not be cause for concern. f The blister usually flattens in 2-3 days and sloughs off in 2-4 weeks. How to care for the treated area f As the blister may be tender for the first few days, you may want to protect it with a band-aid. However, most often it may be left to the air. f In most cases the blister top is a good natural bandage which protects the new skin growing underneath. Attempts to remove the blister before the new skin is ready may produce scarring or infection. f Do not soak treated area (ie, wash dishes, swim, etc) during the first 24 hours.

They remind me ofthe terrible acne I had as a teenager. -Ellen, 35, social worker f you live a full, active life it is impossible not to I acquire a few scars. Some of us see them as badges of honor. Some of us are simply embarrassed by them. How we feel about our scars often has a lot to do with how we got them. For example, a cluster of acne scars, even just one or two ice-pick scars, on an otherwise smooth cheek won't be met with the same acceptance that a scar acquired in a childhood accident might be. My older brother once pushed me off the top bunk bed, sending me to the floor with a new gash over my eyebrow. The scar is now faded and barely noticeable, but when I see it in the mirror, memories of childhood flash briefly in my mind. A scar is the technical term for tissue the body makes to right a wrong.
