Clinical history:

A 30 years old executive complained of an intensive itchy eruption on the back and trunk after a leisure sight-seeing and pleasure trip to Thailand. He denied any history of sexual activities during the trip but had admitted to sunbathing and lying nude on the beach whilst receiving body massage. The massage was very comfortable and he fell asleep for two hours on the beach. The itch was noted in the body immediately after he woke up from sunbathing but it became more intense and persistent for two weeks after returning to Hong Kong. He noted that there was some curious rash developing on his body recently as shown in the picture.
