Standard and Expanded Series Patch Testing Update by the Spanish Contact Dermatitis and Skin Allergy Research Group (GEIDAC). / Actualización de la batería estándar y batería ampliada de pruebas alérgicas de contacto por el Grupo Español de Investigación en Dermatitis de Contacto y Alergia Cutánea (GEIDAC).

After the meeting held by the Spanish Contact Dermatitis and Skin Allergy Research Group (GEIDAC) back in October 2021, changes were suggested to the Spanish standard series patch testing. Hydroxyethyl methacrylate (2% pet.), textile dye mixt (6.6% pet.), linalool hydroperoxide (1% pet.), and limonene hydroperoxide (0.3% pet.) were, then, added to the series that agreed upon in 2016. Ethyldiamine and phenoxyethanol were excluded. Methyldibromoglutaronitrile, the mixture of sesquiterpene lactones, and hydroxyisohexyl 3-cyclohexene (Lyral) were alo added to the extended Spanish series of 2022.

The existence of arthritis in cutaneous panarteritis nodosa (CPAN) is controversial. We report a 52-year-old male with chronic destructive arthritis of both knees and palpable purpura in the feet, where the underlying histological finding was necrotizing arteritis. Systemic involvement was not demonstrated. AntiHBc and antiHBs antibodies were positive. Four of the 11 cases of CPAN with arthritis that we have found reported in the literature were well documented, and only one developed erosions of the joints. Our patient is the first reported case of CPAN with destructive arthritis and evidence of previous hepatitis B virus infection.
