A temporary eruption on the skin.
A breaking out on the skin, either localized or generalized.
A mass of small spots which stays on the skin for a period of time, and then disappears.
A general term for reddish spots or reddish, inflamed skin, often associated with itching or fever and with local irritation, as in diaper rash or heat rash. They are also associated with numerous disorders common in children, such as chicken pox and scarlet fever, as well as some less common diseases such as Rocky Mountain spotted fever, some autoimmune disorders such as lupus erythematosus, and some kinds of vitamin deficiency. Treatment depends on the cause and the type of spots distinguished by a physician.
Skin eruption, usually characterized by red spots or generalized reddening. Rashes occur with chicken pox, measles, and rubella; in cases of local irritation and/or infection (e.g., diaper rash); and in certain other diseases (e.g., butterfly rash or systemic lupus erythematosus).
A flat or raised skin eruption characterized by changes in skin color or texture. Symptoms of rashes vary widely. Redness is common, and many are crusted or blistered. While some rashes cause no physical pain, many cause itching, swelling, and inflammation. Even otherwise symptom-free rashes can be cosmetically disturbing and lead to emotional distress. Rashes are due to a wide variety of causes, including allergic reactions (commonly to drugs or poisonous plants) and bacterial or viral infections. Rashes usually respond well to simple home remedies such as applying cool compresses and soothing lotions and taking over-the-counter antihistamines. However, when rashes are persistent, cause severe discomfort, or are accompanied by fever, it is important to consult a doctor.
A temporary eruption on the skin, usually typified by reddening (either discrete red spots or generalized reddening) and itching. A rash may be a local skin reaction or the outward sign of a disorder affecting the body. Rashes commonly occur with infectious diseases, such as chickenpox and measles.
A general term for any eruption that appears on the skin transiently (as opposed to durable skin lesions such as scars, tattoos, or moles).
A speckled, rosy or crimson skin outbreak that may be accompanied by itching and arises from various causes such as illness, exposure to allergens, consumption of certain foods, or adverse reactions to medication.
A cluster of spots or a region of reddened and irritated skin. Typically, a rash is temporary and infrequently indicates a significant underlying issue. Itching or fever might accompany a rash.
Rashes are categorized based on whether they impact a specific area of the skin (localized) or spread across the whole body (generalized), as well as the specific characteristics of the spots present.
A macular rash consists of spots that are flush with the adjacent skin, differing from it only in terms of color or texture. Nodular and papular rashes consist of small, elevated bumps, which may or may not match the surrounding skin’s color. A bullous rash exhibits sizable blisters, while a vesicular rash has smaller blisters, and a pustular rash contains pus-filled blisters. A butterfly rash manifests as a skin outbreak that stretches across the cheeks, connected by a narrow band over the nose; it is a characteristic feature of systemic lupus erythematosus.
Rashes serve as the primary indicator for numerous infectious diseases, like chickenpox, and are a defining characteristic of various skin conditions, including eczema and psoriasis. Additionally, a rash can signal an underlying medical issue, such as the rashes linked to scurvy or pellagra due to vitamin deficiency. Rashes that typify urticaria (nettle rash) or contact dermatitis may result from allergic reactions. Another frequent cause is drug reactions, particularly in response to antibiotic medications.
Diagnosis relies on observing the characteristics and spread of the rash, assessing any accompanying symptoms, and considering the potential for allergies (such as to medications).
Whenever feasible, the root cause of the rash is addressed. An itchy rash can be alleviated using a soothing lotion like calamine or an antihistamine medication.
