Lichenification is when the skin becomes thick and leathery. It may have a bumpy texture and be darker than surrounding skin. It can have multiple causes including itch and sun damage.
Generally, Leathery neck can be related to:
Psoriatic Arthritis is an inflammatory joint condition associated with the skin disorder Psoriasis, which causes red, scaly patches on the skin. Joint pain, swelling and stiffness are typical signs of Psoriatic Arthritis.
This is a skin condition characterized by the presence of raised, pink bumps that appear in a linear pattern on the skin. While this condition is commonly observed in individuals of various age groups, its exact cause remains unknown.
Allergic rashes. Risk factors include genetics, other allergic diseases, new skin products, and allergic foods. Childhood eczema cases can resolve by adulthood, but it can also occur in adults.
Sometimes, Leathery neck may be related to these serious diseases:
Scedosporiosis is a range of diseases caused by the fungus Scedosporium. These fungi can cause infection in various body organs, usually when the immune system is weakened or compromised.
Your doctor may ask these questions to check for this symptom:

I always like coming to Ubie when I have a multi-symptom problem. I have a hard time recognizing symptoms sometimes, and Ubie asks questions that help include them.
