Hyperhidrosis is the most common type of sweat gland disorder. It may be localized or generalized. The localized type usually occurs in a symmetrical fashion over the palms, soles and armpits as a response to emotional stimuli. Another form of the localized type is idiopathic localized unilateral hyperhidrosis which is very rare and the etiopathogenesis remains unclear. Here, we report a female patient who had localized crossed hyperhidrotic areas on her body (on the left side of the scalp, face and the shoulder and on the right side of the trunk) and also had thyroid gland disease. We herein discuss this extremely rare presentation of the disease and its association with thyroid gland disease.
