Diagnosis
The symmetrical affection of both hands and feet, the history, and the absence of eruptions elsewhere on the skin should make it easy to distinguish this disease from hyperkeratosis due to hard work, from arsenical hyperkeratosis and from hyperkeratosis due to eczema psoriasis, or pityriasis rubra pilaris.
Prognosis. The condition is incurable.
Treatment
This consists of the regular use of emollient Ointments as detailed in the treatment of ichthyosis.
