A case of idiopathic acquired leukonychia totalis in a 17-year-old boy.

Whitening of the nail, or leukonychia, can have a wide range of etiologies including genetic disorders, trauma, poisoning, autoimmune disorders, and infections. Here we detail a case of idiopathic acquired leukonychia totalis in a 17-year-old boy. This condition has been reported 13 times in the literature previously, with only young boys being affected. Proper diagnosis may help minimize unnecessary investigations and prevent additional psychological stress over whether an underlying disease is present.

Gardner-Diamond Syndrome: A Psychodermatological Condition in the Setting of Immunodeficiency.

Gardner-Diamond syndrome (GDS) is a psychological and dermatologic syndrome involving painful, ecchymotic, purpuric lesions that typically appear after a period of stress or minor trauma. This syndrome most commonly occurs in young women, though it has also been less commonly reported in men and adolescents. It is an uncommon condition and appropriate diagnosis is important to properly manage symptoms and minimize risks to patients. Here report a case of GDS presenting in a woman with common variable immunodeficiency (CVID), which, to the best of our knowledge, is not a comorbid condition that has previously been reported in correlation with GDS.
