Under the wood lamp examination, some of the lesions fluoresced into yellowish gold. What can be done to treat and avoid the recurrence of the disease? Based on the clinical appearance of the lesions, what diagnosis can you infer? This is caused by what organism?

This 19-year-old college student went to the Student Health Services because she had a slowly developing rash on both earlobes, hands and wrist, and around her neck. Her medical history revealed that she had eczema in childhood. During her early teens, she had facial acne, for which she was given tetracycline. Physical examination revealed a rash of erythema and small blisters, with marked excoriation because of the itching. Her hands were red, scaly, and dry. The rash on her hands was different from the eruptions on her neck and ears. A contact hypersensitivity was suspected. Follow-up patch tests included a standard battery of agents—rubber, cosmetics, plant extracts, perfumes, nickel, and makeup. Strongly positive reactions for rubber and nickel were observed. The student was advised to eliminate contact with rubber (e.g., rubber gloves) used at home or on the job. Her jewelry probably contained nickel and was believed to be the source of the irritation to her earlobes, neck, and…

Three-week-old Xavier Capelleto was brought to the emergency room with a bright scaly rash that first developed on his legs and then spread to his trunk and face. He also had blisters on his palms and the soles of his feet. Xavier’s parents said that he had been experiencing looser bowel movements than expected, a large amount of yellow pus had been accumulating around his swollen eyelids, and he showed signs of oral thrush.

His parents were told that Xavier had an autosomal recessive form of severe combined immunodeficiency (SCID) known as Omenn syndrome, which affects the development of both B cells and T cells. A bone marrow transplant was recommended; however, Xavier died from respiratory failure due to an opportunistic bacterial infection.…
