• PAX8+ tumors
  11 September

  PAX8-expressing tumors
  Definition; PAX8 is a paired-box gene important in embryogenesis of the thyroid, Müllerian tract, and renal/upper urinary tracts. PAX8 is a highly sensitive marker for thyroid tumors, renal tumors, Müllerian tumors, and thymic tumors. Importantly, all lung adenocarcinomas, breast and adrenal neoplasms, and the majority of gastrointestinal tumors are negative for PAX8.

• familial angiolipomatosis
  4 September

  Familial angiolipomatosis, which is a benign, autosomal-dominant condition that may be regarded as a subtype of familial multiple lipomatosis (FML) or as a distinct entity.
  Management of this condition may include liposuction or surgery to reduce the tumor burden.
