Tinea corporis can often be diagnosed on the basis of a positive potassium hydroxide examination. Topical and systemic antifungals are usually curative. Pityriasis rosea is characterized by small, fawn- colored lesions distributed along skin cleavage lines. Erythema annulare centrifugum Erythema anulare centrifugum; Classification. Some of the types include annular erythema (deep and superficial), erythema perstans, erythema gyratum perstans, erythema gyratum repens, darier. Granuloma annulare, patch type Frank C Victor MD, Stephanie Mengden MD Dermatology Online Journal 14 (5): 21. Treatment is symptomatic. Granuloma annulare is characterized by nonscaly, annular plaques with indurated borders, typically on the extremities. One half of cases resolve spontaneously within two years. Sarcoidosis can present as annular, indurated plaques similar in appearance to the lesions of granuloma annulare. Diagnosis is based on histopathology and the involvement of other organ systems. Hansen's disease can mimic tinea corporis by presenting as one or more annular, sometimes scaly, plaques. Urticaria may affect 1. The annular plaques lack scale and are evanescent. Subacute cutaneous lupus erythematosus can present in an annular form on sun- exposed surfaces or in a papulosquamous form. Erythema annulare centrifugum typically presents as annular patches with trailing scale inside erythematous borders. LE, M. D., and MOHAMAD R. KHOSHEVIS, M.

Subacute cutaneous lupus erythematosus can present in an annular form on sunexposed surfaces or in a papulosquamous form. Erythema annulare centrifugum typically presents as annular patches with trailing scale inside erythematous borders. The term âannularâ stems from the Latin word âannulus,â meaning ringed.
Using a scalpel blade, the scales are scraped at the active border of the lesion, with particular care not to cause pain or bleeding. The specimen is transferred to a glass slide, and a coverslip is placed on top to protect the specimen. A drop of 1. 0 to 1. KOH, with or without dimethyl sulfoxide (DMSO; Rimso- 5. The specimen is then gently heated; specimens prepared with DMSO do not require heating. Overheating or boiling the specimen may cause the KOH to crystallize, which leads to artifacts. First, the specimen should be examined under low- power magnification. The KOH and the heat dissolve the keratinocyte cell membrane, leaving behind easily visualized septate hyphae, which are long and may be straight or wavy. These structures may also branch and generally have a uniform diameter. If repeated KOH preparations are negative in a patient with a clinically suspected dermatophyte infection, fungal cultures are recommended. The cultures may take two to four weeks for growth. TREATMENT OF TINEA CORPORIS The herald patch is generally a singular, ovoid macule located on the trunk and can range from 2 to 1. These lesions are generally bilaterally symmetric and may be located anywhere on the body, especially on the neck, trunk and proximal extremities. Because the lesions follow the skin cleavage lines, they have the characteristic appearance of a Christmas tree.
Subcutaneous granuloma annulare is characterized by large, skin- colored nodules that may be as deep as the lower dermis or subcutaneous fat.
Diagnosis is typically based on clinical appearance and correlation with pathology. Laboratory tests are generally of little benefit
The typical skin changes may wax and wane and may include infiltrated papules and plaques, subcutaneous nodules and infiltration of old scars.
Topical or intralesional corticosteroids may be beneficial for localized skin disease.
Urticaria may affect 1. Following the release of histamine and other mediators, increased vascular permeability results in massive edema of the superficial dermis.
This mechanism is associated with urticaria caused by pollens, foods, medications, fungi, molds, Hymenoptera venom and parasitic infections. Antibody- dependent, cell- mediated cytotoxicity (type II hypersensitivity) and antigen- antibody complexes (type III hypersensitivity) and activation of the complement system account for the urticaria occurring in persons with transfusion reactions and serum sickness, respectively. Physical urticaria includes pressure urticaria, which appears under sites of tight clothing, on the soles and wherever a heavy load is carried; cold urticaria, which usually occurs on the hands, ears, nose and the cooler fatty areas, such as lateral thighs in women; cholinergic urticaria, which is usually precipitated by fever, hot baths or exercise; solar urticaria; and dermograph urticaria. In most cases of urticaria, the specific etiology remains unclear. A lesion of urticaria usually lasts between 9. Urticarial vasculitis is not actually urticaria but a leukocytoclastic vasculitis that can mimic urticaria clinically, with the exception that the lesions may persist up to three to five days. In these patients, a skin biopsy for histopathologic confirmation of vasculitis is warranted. SCLE Subacute cutaneous lupus erythematosus (SCLE) presents either in an annular Patients with SLE commonly present with arthralgias or arthritis, low grade fever, malaise or myalgias. Systemic disease is mild to moderate, and the incidence of renal disease is low.
The Sj. It has been shown that SSA/Ro antibodies, which are present in the nucleus and cytoplasm, are translocated to the surface of the cultured keratinocytes under UVB light. University of Maryland Medical Center. Treatment Options. Prevention. Treat underlying diseases and avoid known triggers (certain medications, for example). It is also important to avoid the sun when taking certain medications. Treatment Plan. Your doctor will treat any underlying diseases, stop any drugs that may contribute to symptoms, and take steps to control your current symptoms. Mild cases may not require treatment. Bed rest and medication may be necessary for more severe cases. Drug Therapies. Antihistamines for itching. Antibiotics. If you have an infection, though research suggests many cases of erythema can be resolved without antibiotics. Antiviral medications such as acyclovir and valacyclovir, if you have a virus. Aspirin and nonsteroidal anti- inflammatory drugs (NSAIDs)Burrow's compresses, a solution used to soothe skin conditions, particularly blisters. Corticosteroids, applied to the skin (topically); corticosteroids may also be taken orally to reduce symptoms of erythema nodosum. Intravenous immunoglobulin, used experimentally for SJS and TENPhotomodulation therapy, use of a light- emitting diode to accelerate the resolution of erythema Complementary and Alternative Therapies. To treat erythema, you must treat the underlying cause. It is important to get a proper diagnosis from your doctor before using complementary and alternative therapies (CAM). Not all CAM therapies are appropriate for all people, and some may interact with conventional medicines or therapies. You should use CAM therapies only under the guidance of a physician. Some CAM therapies may be used to: Reduce inflammation. Boost the immune system. Prevent infections Nutrition. Antioxidants are molecules that scavenge free radicals (chemicals that can damage cells). Antioxidants also may protect skin against damage caused by ultraviolet (UV) sun rays. The following antioxidants have been shown to protect skin against damage in scientific studies: Beta- carotene and other carotenoids (up to 3. IU per day for beta- carotene): Beta- carotene is often used as a standard treatment for sun sensitivity, although studies have been mixed. In one trial, though, 2. E. Both groups improved significantly, but vitamin E did not appear to add any benefits. Scientists think the protective effect of beta- carotene comes from its antioxidant effect, so it's possible other antioxidants may also help protect skin from damage. Vitamin B6 (1. 00 mg per day for 3 months): Some case reports suggest that vitamin B6 can help reduce the reaction to sunlight. You should only take high doses of vitamin B6 under a doctor's supervision, because of the risk of side effects. Vitamin B6 can interfere with Amiodarone (Cordarone), Phenobarbital (Luminal), Phenytoin (Dilantin), and possibly Levodopa. Speak with your physician if you are taking any of these medications. Vitamin C (1 to 3 g per day, lower dose if diarrhea develops): Vitamin C is an antioxidant, so it may provide some protection against skin damage from sunlight. Vitamin C can negatively impact certain health conditions, and can interfere with some medications. Speak with your physician. Vitamin E: Vitamin E is also an antioxidant, and a few studies have shown that it can offer protection from sun damage to skin when taken with vitamin C (but not alone). However, other studies have not found the same results. Vitamin E may interact with certain medications, including but not limited to, blood- thinning medications, such as warfarin (Coumadin). It may also have negative effects on people with bleeding disorders, head and neck cancers, Retinitis Pigmentosa, and other conditions. Vitamin D: In animal studies, vitamin D helped protect against damage from UVB rays. It is not clear yet whether vitamin D supplements may protect humans in the same way. Vitamin D can interact with some medications, including but not limited to, Digoxin and Verapamil. It may also have a negative impact on some health conditions. Speak with your physician. Other Supplements. Melatonin: Applying melatonin topically (either alone or in combination with vitamin E) seems to offer some protection against sunburn in healthy people, but it is not known whether melatonin also lessens effects in people prone to erythema. Zinc: Zinc is necessary for healthy skin and was used in a study along with other prescription medications as a treatment for a severe form of erythema multiforme similar to TEN. In the study, 5 out of 8 people treated with zinc showed a benefit. Because high doses of zinc can be dangerous, many doctors suggest doses below 5. Talk to your doctor to determine which dose is right for you. Zinc can interact with certain antibiotics, Cisplatin, Amiloride, and Penicillamine (used for Wilson syndrome and Rheumatoid arthritis). Herbs. Flavonoids: Some of these plant- based antioxidants may protect skin from sun damage in healthy people. In one study, German researchers found that drinking high flavonol cocoa offered protection from the sun (the cocoa used was a special formulation that is not available commercially). In another study, pomegranate fruit extract helped protect skin cells in a test tube from UV light. It is not yet known whether taking the extract would provide any benefit. However, adding fruits and vegetables to your diet to eat more flavonoids may help. You can also take these flavonoids in dried extract form. Speak with your physician first, since certain flavonoids can interact with prescription medications: Catechin, quercetin, hesperidin, and rutin. Rose hips (Rosa canina) are also high in flavonoids and may be used as a tea. Drink 3 to 4 cups per day. Hesperidin methyl chalcone is a water- soluble form of quercetin that may act as an antihistamine. Green tea (Camellia sinensis) may also protect against erythema caused by UV light because it contains antioxidants. Herbs traditionally used topically to heal damaged skin, promote lymph circulation, and possibly treat the underlying cause of various skin conditions may be helpful. You should check with your doctor before using any of these remedies. Some examples include: Aloe vera: Used topically for skin inflammation. One study found that aloe vera displayed anti- inflammatory effects superior to 1% hydrocortisone gel. Burdock root (Arctium lappa): Used topically for skin inflammation and wound healing. Never apply to an open wound. Calendula (Calendula officinalis): Used topically for burns, wounds, and other skin conditions. Never apply to an open wound. Goldenseal (Hydrastis canadensis): Used for infections, including those causing skin lesions. Lemon balm (Melissa officinalis): Can be applied to HSV lesions as a cream or a wash. Sage extract: Applied topically to reduce inflammation. In one study, sage extract significantly reduced the ultraviolet induced erythema to a similar extent as hydrocortisone. Slippery elm (Ulmus fulva): Applied topically, in combination with goldenseal root. Never apply to an open wound. Yarrow (Achillea millefolium): Applied topically for skin inflammation and wound healing. Never apply to an open wound. Homeopathy. Although few studies have examined the effectiveness of specific homeopathic therapies, professional homeopaths may consider the following remedies for the treatment of erythema based on their knowledge and experience. Before prescribing a remedy, homeopaths take into account a person's constitutional type, includes your physical, emotional, and psychological makeup. An experienced homeopath assesses all of these factors when determining the most appropriate treatment for an individual. Apis mellifica: For skin rashes that feel hot and dry and are sensitive to touch; may be accompanied by sore throat. Symptoms are relieved by cool drinks and baths and worsened by heat and warm liquids. This remedy is most appropriate for individuals who often feel sad, disappointed, or even depressed. They tend to cry easily, but may also be irritable and envious by nature. They are also not thirsty but may crave milk. Calendula: For burns and skin lesions that are fairly superficial. This remedy is often used after the acute phase of the skin condition has subsided to aid in complete recovery. Rhus toxicodendron: Used for blisters and vesicles accompanied by intense itching that worsens at night and improves with the application of heat. This remedy is most appropriate for individuals who are generally restless and unable to get comfortable at night. Sulphur: For skin disorders that are accompanied by fever and intense itching. This remedy is most appropriate for individuals who are thirsty, irritable while sick, lazy, and messy under ordinary circumstances, and who describe a sensation of internal heat and burning. Symptoms tend to improve with open, cold air and worsen with warmth. Supporting Research. Beers MH, Porter RS, et al. The Merck Manual of Diagnosis and Therapy.
