Minor features of TSC include the following:

  • Multiple randomly distributed pits in dental enamel [11]

  • Hamartomatous rectal polyps: Histologic confirmation is suggested.

  • Bone cysts: Radiographic confirmation is sufficient.

  • Cerebral white matter radial migration lines: Radiographic confirmation is sufficient. One panel member felt strongly that 3 or more radial migration lines should constitute a major sign.

  • Gingival fibromas

  • Nonrenal hamartoma: Histologic confirmation is suggested.

  • Retinal achromic patch

  • "Confetti" skin lesions

  • Multiple renal cysts
