• Wilms tumor-neuroblastoma familial association
  27 January 2010

  Wilms tumor and neuroblastoma are childhood tumors of the kidney and undifferentiated neural crest cells, respectively. Both disorders are primarily sporadic, but familial Wilms tumor pedigrees and familial neuroblastoma pedigrees are each well recognized and account for approximately 1-3% of each tumor type.
  Families with both Wilms tumor and neuroblastoma represent a previously unrecognized familial cancer syndrome in which the underlying predisposition gene(s) remain to be determined. (...)

• MUTYH-associated polyposis
  5 June 2009

  MAP; MYH-associated polyposis
  Definition: MUTYH-associated polyposis (MAP) is a recessively inherited disorder which predisposes biallelic carriers for a high risk of polyposis and colorectal carcinoma (MAP-CRC).
  This recently recognized type of adenomatous polyposis was first documented in a Welsh kindred in which three siblings had multiple colorectal adenomas and carcinomas but lacked a germline APC mutation.
  MUTYH-associated polyposis (MAP) may be difficult to distinguish from (...)

• renal oncocytosis

  renal oncocytomatosis
  Definition: Renal oncocytosis is a rare disorder in which numerous oncocytic nodules develop in the kidney. Renal oncocytosis is a precursor lesion of renal oncocytoma and chromophobe renal cell carcinoma.
  The renal cell neoplasms of oncocytosis seem to have distinct morphologic, immunohistochemical, and cytogenetic profiles and likely are a distinct entity, not closely related to oncocytoma or chromophobe renal cell carcinoma. (#20305535#)

• Maffucci syndrome
  19 June 2003

  Maffucci, Maffucci disease, hemangiomatosis osteolytica
  Definition: Maffucci syndrome consists of multiple cutaneous hemangiomas, dyschondroplasia, and enchondromas with potential for malignant change. It is a subtype of enchondromatosis (Ollier disease) (MIM.166000) associating hemangiomas. As multiple enchondromatosis, Maffucci disease is caused by mutation in the PTH/PTHRP type I receptor (PTHR1) (MIM.168468).
