Glossary for Itching skin

Medical terms related to Itching skin or mentioned in this section include:

• $18p minus syndrome$: A rare chromosomal disorder where a portion of chromosome 18 is missing which is characterized by mental and growth deficiencies, drooping upper eyelid and prominent ears. The type and severity of symptoms is determined by the amount of genetic material that is missing.
