Club Med dermatitis
A photodermatitis consisting of linear, mirror-image, hyperpigmented tender oedematous patches with scalloped edges located on the skin of the inner thighs.
The condition was described in a person who played a drinking game in which participants rolled limes up and down their thighs: furocoumarin–present in citrus fruits, celery, parsley elicits erythaema and vesiculation, if the skin is subsequently exposed to light. The reaction was first described in 1916 in women wearing oil of bergamot.
Synonyms Mexican beer dermatitis, phytodermatitis (in part)
