2. visible efflorescent lesions of the skin due to disease, with redness, prominence, or both; a rash. adj., adj erup´tive.
creeping eruption
1. a peculiar eruption that appears to migrate, due to burrowing beneath the skin by certain larvae; it has the appearance of subcutaneous tunnels that are red and vesicular at the advancing end and dry and encrusted at older portions.
drug eruption an adverse cutaneous reaction produced by ingestion, parenteral use, or local application of a drug, which may produce various morphologic patterns and types of lesions; called also dermatitis medicamentosa.
Kaposi's varicelliform eruption a generalized and serious vesiculopustular eruption of viral origin, superimposed on preexisting atopic dermatitis; it may be due to the herpes simplex virus (eczema herpeticum) or vaccinia (eczema vaccinatum).

(ē-rŭp'shŭn),
1. A breaking out, especially the appearance of lesions on the skin.
2. A rapidly developing dermatosis of the skin or mucous membranes, especially when appearing as a local manifestation of one of the exanthemata; an eruption is characterized, according to the nature of the lesion, as macular, papular, vesicular, pustular, bullous, nodular, erythematous, etc.
3. Passage of a tooth through the alveolar process and perforation of the gums.

eruption

(e-rup'shon) [L. eruptio, outbreak]

active eruption

Movement of the tooth toward the occlusal plane.

creeping eruption

A skin lesion marked by a tortuous elevated red line that progresses at one end while fading out at the other. It is caused by the migration into the skin of the larvae of certain nematodes, esp. Ancylostoma braziliense and A. caninum, which are present in ground exposed to dog or cat feces.
Synonym: cutaneous larva migrans

delayed eruption

The most common variation in the tooth eruption pattern. It may be due to crowding or to various genetic, endocrine, or physiological factors.

DRUG ERUPTION

drug eruption

Dermatitis produced in some patients by application or ingestion of drugs. Drug rashes usually appear on the trunk (chest and back). See: illustration

fixed drug eruption

A localized red rash with a sharp border, which follows exposure to a drug. The rash usually burns, occurs on the face or the genitals, and, if the offending agent is given again, recurs in the same location.

passive eruption

Increased size of the clinical crown of a tooth by apical migration of the attachment epithelium and periodontium.

polymorphous light eruption

, polymorphic light eruption Abbreviation: PMLE
A rash occurring after exposure to sunlight, typically consisting of papules, plaques, or papulovesicles on sun-exposed skin. It is more common in fair-skinned patients and in women than in men or people with darker skin color. The rash is usually itchy but may produce a burning or stinging sensation. Avoiding sun exposure with protective clothing and sunblock helps prevent PMLE. Immune-modulating drugs are available for refractory cases.

seabather's eruption

Itching red papules that may appear on the skin within a few hours of swimming in saltwater. The rash is caused by the sting of the larval forms of the thimble jellyfish or the sea anemone. The rash is usually more prominent under swimsuits than on exposed skin because the pressure of clothing on the skin releases the stinging barbs of the larvae. The swimsuit should be washed before it is worn again. Treatment is symptomatic, with oral antihistamines or topical corticosteroids.

serum eruption

An eruption that occurs following the injection of serous fluid. It may be accompanied by chills, fever, and arthritic symptoms.

eruption

1. A skin rash.
2. The emergence of a tooth through the gum.

Eruption

The process of a tooth breaking through the gum tissue to grow into place in the mouth.

e·rup·tion

(ē-rŭpshŭn)
1. Passage of a tooth through the alveolar process and perforation of the gingiva.
2. A breaking out, especially the appearance of lesions on the skin.
[L. e-rumpo, pp. -ruptus, to break out]

Patient discussion about eruption

Q. What is the cause of my head rash? I have a rash on my head. It is red and itchy, what could it be from?

A. A head rash can be caused from lots of different things. I found a website that helps you diagnose it with charts:

Q. What do I do with this horrible Diaper Rash?? I have no idea what is up with my daughters diaper rash, she is a year old and I do everything to keep this rash from coming, but it comes back! All week I have let her run without a diaper on trying to let it air out as much as possible, (thank god for carpet shampooers).Is there any secret that someone has to getting rid of this rash?

A. My own daughter was yeasty from whatever they do to newborns in the hospital and I battled it ever day until I started taking garlic gel tabs. Because I breasfed her she got all the benefits of it and her bottom cleared right up.
Probiotics can help, yogurt, kefir and the like. Super Salve from supersalve.com is amazing in its healing abilities. Avoid processed foods and especially sugars.
