A group rare skin tumor or hamartoma diseases characterized by a germline PTEN mutation and clinical manifestations of hamartomas, overgrowth, and increased risk of neoplasia, notably breast carcinomas, epithelial thyroid carcinomas, endometrial carcinomas, renal cell carcinomas, and colorectal carcinoma. Non-malignant manifestations include macrocephaly, benign thyroid pathology (especially Hashimoto thyroiditis), mucocutaneous hamartomas, colonic polyps, and vascular malformations.
