If the above five steps fails to help people who suspected of having a genodermatosis to obtain the diagnosis result, they should keep all their information such as the diagnosis record and the clinical manifestations at different stages, and continue to record the changes of the body, waiting with a positive attitude, the future medicine may give the answer. Therapy
The therapy of genodermatosis not only needs to take care of patients skin, reduce their pain and prevent complications, but also needs to carry out mental support for patients and their families. Prevention and care
Different types of genodermatosis require different kinds of prevention and care. Ichthyosis
There is no radical therapeutic method for ichthyosis, but some care can ease the symptoms. To prevent skin thickening and hydrate skin, patients can apply a cream containing alpha hydroxy acids and patients can also be treated with antibiotics for subsequent infections. Epidermolysis bullosa
For epidermolysis bullosa, daily care is important. When treating a wound, keep it clean and reduce friction, the bandages and dressing used must be non-sticky and gentle, and the patient should wear loose clothing to avoid damaging the wound. Epidermolytic hyperkeratosis
The treatment of Epidermolytic hyperkeratosis is mainly control and alleviate symptoms, and good nursing can reduce the incidence of complications like electrolyte disturbances and sepsis. To improve the look and feeling of the skin, patients can apply a cream containing alpha hydroxy acids, glycerol and urea, and if necessary, patients can use antibiotics to control secondary infections.
A trichilemmal cyst  is a common cyst that forms from a hair follicle, most often on the scalp, and is smooth, mobile, and filled with keratin, a protein component found in hair, nails, skin, and horns. Trichilemmal cysts are clinically and histologically distinct from trichilemmal horns, hard tissue that is much rarer and not limited to the scalp. Rarely, these cysts may grow more extensively and form rapidly multiplying trichilemmal tumors, also called proliferating trichilemmal cysts, which are benign, but may grow aggressively at the cyst site. Very rarely, trichilemmal cysts can become cancerous. Classification
Trichilemmal cysts may be classified as sebaceous cysts, although technically speaking are not sebaceous. "True" sebaceous cysts,  which originate from sebaceous glands and which contain sebum, are relatively rare and are known as steatocystoma simplex or, if multiple, as steatocystoma multiplex. Medical professionals have suggested that the term "sebaceous cyst" be avoided since it can be misleading. : 31  In practice, however, the term is still often used for epidermoid and pilar cysts. Pathogenesis
Trichilemmal cysts are derived from the outer root sheath of the hair follicle. Their origin is currently unknown, but they may be produced by budding from the external root sheath as a genetically determined structural aberration. They arise preferentially in areas of high hair follicle concentrations, so 90% of cases occur on the scalp. They are solitary in 30% and multiple in 70% of cases.Histologically, they are lined by stratified squamous epithelium that lacks a granular cell layer and are filled with compact "wet" keratin.
