At the time of consultation, the female patient whose back is shown in Fig. 5.1 was aged 54 years. She complained of having itchy rashes on her lower back. The rashes also affected her armpits and under the breasts [1]. Having had no similar rashes previously, she strongly believed that they were associated with her sharing her bedding and clothing with a long-time friend who visited her [2]. This belief was predicated on the fact that the friend had similar rashes, and when her visitor scratching her body, she enquired and the response she received was that some of the pupils she taught had similar rashes. The friend’s visit was 3 months earlier, and the visit was for 2 weeks. She noticed itching 3 weeks after her friend’s visit ended, and this was soon followed by the rashes. Initially, the rashes were few, but they had become many and intensely pruritic. On enquiry, she could not associate greater intensity of pruritus during nighttime despite the specificity of the question. She was definite that there was no aggravation or relief from bathing with water and her normal soap. She said that since the onset of the rashes there has been none on her face. She did not have any on the webs of her fingers or toes. She felt very inconvenienced by the rashes. She indicated that she had used a couple of drugs including benzyl benzoate that was suggested to her to apply, but there was improvement.
