Germline mutations in the LKB1/STK11 gene cause characteristic hamartomas and freckling to develop in patients with Peutz-Jeghers syndrome (PJS). The hamartomas arise as a result of somatic "second hits" at LKB1/STK11 and therefore contain a neoplastic element. The origin of the pigmented lesions in PJS is unknown and difficult to test, as these are hardly ever biopsied. PJS patients are at increased risk of...
