Sample item

Which distribution is typical of seborrhoeic dermatitis?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Scalp, eyebrows, and nasolabial folds

Seborrhoeic dermatitis favors sebum-rich areas such as scalp, eyebrows, nasolabial folds, and central chest, often with greasy scale.

Option by option

  • A. Scalp, eyebrows, and nasolabial folds (correct)

    Correct: sebaceous areas are the characteristic distribution.

  • B. A single unilateral dermatome

    Dermatomal distribution suggests zoster.

  • C. Palms and soles only

    Palms and soles have a different dermatosis differential.

  • D. Deep flexural ulcers

    Deep ulcers are not a usual seborrhoeic feature.
