Seborrheic Dermatitis

Seborrheic dermatitis is a red, scaly,  rash seen in sebum rich areas including the scalp, eyebrows, behind the ears, sides of the nose, mid chest,  the groin, under the breast, navel and armpits.  In addition to sebum, this dermatitis is linked to Malassezia,1 immunologic abnormalities, and activation of complement. The severity varies from mild dandruff to exfoliative erythroderma. (emedicine)

Causes

It is commonly aggravated by changes in humidity, changes in seasons, trauma (eg, scratching), or emotional stress.
