Acanthoma
Acanthoma (/əˌkænˈθoʊmə/), derived from the Greek words 'akantha' meaning 'thorn' and '-oma' meaning 'tumor', is a type of benign tumor that originates from the epithelial cells of the skin.
Etymology
The term 'Acanthoma' is derived from two Greek words: 'akantha' which means 'thorn' and '-oma' which is a suffix used in medical terminology to denote a tumor or growth. Thus, 'Acanthoma' essentially refers to a 'thorny tumor'.
Definition
Acanthoma is a benign neoplasm that originates from the epithelial cells of the skin. It is characterized by the proliferation of prickle cells, which are a type of epithelial cell. These cells are named for their spiny, or 'thorny', appearance under the microscope.
