Nodule

A nodule is a solid, palpable, usually deeper skin lesion that is larger and more substantial than a papule.

In acne, nodules develop from substantial inflammation within deeper portions of the follicle and surrounding tissue. They can be painful and may persist for longer than superficial lesions.

Nodular acne can cause significant tissue damage and increase the risk of permanent scarring.

COMMONLY CONFUSED WITH

  • Papule: smaller and more superficial.
  • Cyst: a true cyst has a specific tissue-lined structure; “cyst” is sometimes used loosely to describe severe acne nodules.
