"Pachydermia" Natural Recordings by Native Speakers
Pachydermia refers to a condition characterized by abnormally thick skin, particularly on the hands and feet. It can be a symptom of certain medical conditions, such as eczema, psoriasis, or vitamin deficiencies. The term specifically refers to the thickening of the skin on the palmar surface of the hands or plantar surface of the feet, which can cause discomfort, itching, and difficulty moving the affected joints.
Pachydermata refers to a group of large, herbivorous mammals characterized by their thick skin and helmets-like bone structures on their heads. Examples of pachydermata include elephants, rhinoceroses, and hippopotamuses. The term comes from the Greek words "pachys" meaning thick and "derma" meaning skin.
A pachymeter is a medical device used to measure the thickness of the cornea, which is the clear outer layer of the eye. The measurement is typically taken to diagnose and monitor conditions such as glaucoma, keratoconus, and Fuchs' dystrophy, as well as to plan and follow up on surgical procedures.
