Classic markers detect the majority of cases of fragrance contact allergy. We recommend incorporating FM II in the Spanish baseline series, as in the European baseline series, and using a specific fragrance series to study patients allergic to a fragrance marker.

Allergic contact dermatitis was the most usual diagnosis in our series of children with hand eczema. We recommend patch testing of all children with chronic hand eczema, as is already performed in adults.

A correlation exists between the concentrations of DMF in the different parts of the shoe and the localization of the lesions. Although DMF is a volatile substance, it can remain impregnated in shoes for a long period of time.

Contact allergy to beryllium chloride may not be as unusual as the literature suggests. In order to avoid undetected contact allergies, we recommend performing later readings, between D7 and D10, whenever patch testing is performed with beryllium chloride. Active sensitization may occur.

"Cauliflower ear" is a perichondritis of the auricular pavilion, usually caused by infection or repeated trauma. In children, this entity is considered infrequent. We present the case of a 10-year-old girl living in a child care institution with "cauliflower ear" that was interpreted as a possible sign of child abuse.

Extramammary Paget's disease is an uncommon intraepithelial adenocarcinoma which occurs in areas rich in apocrine glands. Although surgery is the treatment of choice, numerous noninvasive treatments have been tried. There are studies that have demonstrated the efficacy of imiquimod to treat Extramammary Paget's disease, but we found no mention in the literature of its use as neoadjuvant therapy previous to surgery excision. We present a case of a large plaque of extramammary Paget's disease successfully treated with imiquimod and minor surgery of the residual disease.
