Cowden syndrome, also known as Cowden disease, is constellation of findings due to a PTEN gene mutation.

Molecular

  • Phosphatase and tensin homolog (PTEN) mutation.[1]
  • Autosomal dominant inheritance.[2]

Trivia

  • The PTEN gene is located on chromosome ten.
  • Several syndromes are associated with PTEN mutations:[3][1]
    • Bannayan-Riley-Ruvalcaba syndrome (BRRS).[4]
    • Proteus-like syndrome.[5]
    • Lhermitte-Duclos disease.[5]

Clinical

Features:[6]

Lame mnemonic PATH:[7]

  • Papilloma (oral).
  • Acral keratosis.
  • Trichilemmoma.
  • Hamartomatous polyps.

Cancer

Strong association with cancer:[8]

Microscopic
