undiagnosed itchy palms

[lesherrn]

My daughter (14y) has intermittent raised white partially round lesions (sometimes small straight lines or dots) under the skin on her palms and soles. When they show, they itch so badly that they hurt. If she scratches them, they get extremely raised and white. They go away and more return. No scaly patches. No red rings. It is not tinea (ringworm). No contact derm issues. No other physiologic symptoms. Help! Our physician is stumped and I have been searching the internet and she is in distress.

Good answer! That is the same thing that a pediatrician suggested with my description until he saw it. The thing with these raised, white rings/lines are that they are underneath the surface and they are firm, not fluid filled. However, we did try to soak her palms in a bleach solution which is an older treatment for dishydrosis. It did not work. But I still believe that this is something else only because the lesions are so firm and underneath. Any other suggestions, because I definitely appreciate the first one!

Hi

What comes to mind here is dishydrosis or pompholyx. “The name pompholyx comes from the greek word for bubble, which accurately describes this disorder. The vesicles tend to erupt on the sides of the fingers and palms, and often on the dorsal aspect of the distal fingers, where the skin is anatomically similar to that of the palms. The condition can also affect only the feet. Some patients have involvement of both the hands and feet.” Thus, this skin condition may appear as whitish fluid filled bumps  that appears beneath the skin. They may also be covered by a somewhat thick membrane. The vesicles are extremely itchy and they do not pop readily. They may involve the hands, fingers and the soles of the feet.

Is this similar to your daughter's case? You may ask your doctor about this as a differential.
