ICD-11 EB90.23 — Tendinous xanthoma

Tendinous xanthomata manifest most commonly as subcutaneous nodules attached to the extensor tendons over the knuckles or the Achilles tendon, though other tendons can sometimes be affected. They are most frequently seen in familial hypercholesterolaemia but may also be associated with secondary hypercholesterolaemia due to prolonged cholestasis.
