Pityriasis pityriasis

Pityriasis pityriasis, or lichenoid tilor, is a dermatological disease characterized by skin rashes in the form of papules that look like tiny grains of salt. The chronic form of the disorder is hyperkeratosis of the scalp, mainly the vertex area and interdigital folds of the hands. Lichenoid pyoderma is a complication of other chronic skin diseases in which hair follicles are formed in which yeast-like fungi of the genus Malassezia species multiply.

In more complex, advanced forms, the disease affects the nerves and leads to severe pain while walking and difficulty maintaining balance.
