seborrheic [seb″o-re´ik]

1. affected with or of the nature of seborrhea.

2. pertaining to those areas of the body whose sebaceous glands are abundant, as the scalp, face, and axillae.

seborrheic dermatitis an inflammatory condition, usually of the skin of the scalp, with yellowish greasy scaling of the skin and itching. A mild case in the scalp is called dandruff. Seborrheic dermatitis can involve other areas such as the face, neck, central part of the trunk, or axilla. The underlying cause is not known; the hair and scalp may be excessively oily, but the connection (if any) between this and the dermatitis is not known. Although there is no specific cure for dandruff, various measures are used to control and relieve it. Most patients can control scalp scaling by frequent use of a shampoo containing zinc pyrithione, selenium sulfide, or tar. The dermatitis responds well to hydrocortisone cream.
