Other forms of eczema in adulthood

Seborrhoeic dermatitis
In infancy, seborrhoeic dermatitis is also commonly known as ‘cradle cap’ (infantile seborrhoeic dermatitis) and occurs on the scalp, face, flexures, nappy area and occasionally can be generalised. It presents with erythema and yellow greasy scales; it is self-limiting, not itchy and generally resolves over several weeks (see Figure 9.2). The aetiology of seborrhoeic dermatitis is unclear but it is believed to be an inflammatory reaction related to the proliferation of a non-pathogenic skin flora, yeast called Malassezia furfur (formerly known as Pityrosporum ovale). Increased keratinocyte and sebocyte turnover may also play a part.

Juvenile plantar dermatoses
This is a condition mainly affecting school-aged children. It occurs exclusively on the plantar regions of the feet (soles) with glazed erythema and painful fissuring. This is a form of dermatitis which is related to the continual wearing of synthetic footwear (Burns et al., 2004).

The following other forms of eczema are more likely to be seen in the middle-aged patient, although these can present in any age group.
