Keywords: allergic contact dermatitis; allergic contact dermatitis syndrome; case report; complications; lymph node; lymphadenopathy; methylisothiazolinone; methylisothiazolinone/methylchloroisothiazolinone; patch test; side-effect EN allergic contact dermatitis allergic contact dermatitis syndrome case report complications lymph node lymphadenopathy methylisothiazolinone methylisothiazolinone/methylchloroisothiazolinone patch test side-effect 136 138 3 01/28/21 20210201 NES 210201 Patch testing is the standard diagnostic procedure for allergic contact dermatitis (ACD), the purpose of it being to reproduce a "miniature" eczematous reaction on the skin by applying the allergens occluded according to international consensus guidelines.1 Lachapelle et al developed the concept of "allergic contact dermatitis syndrome" (ACDS), which implies three consecutive stages with specific morphological aspects and symptoms.2 Stage 2 is linked to the regional dissemination of the allergen(s) to the lymph nodes from the primary site of exposure via the lymphatic vessels.2 Although patch tests are generally very safe, some complications have been described. The reactive lymphadenopathy may seem distant from the patch test reaction in both of the previously published cases by Wong and Maibach,3 and our case (patch tests reactions from methylisothiazolinone located on the left site of the lumbar region).
