  Hyperplastic polyp of colon PO
  Definition: Hyperplastic polyps are one ofthe most common polyp types seen in the adult colon. Hyperplastic polyps (HP) are the most common serrated lesions that are more likely to be found in the distal colon and generally small in size (<5 mm). Only rare HPs are >1 cm. Endoscopically, HPs can be difficult to distinguish from adenomas.
  Histologically, HPs are characterized by a simple tubular architecture with elongated and straight crypts and by (...)

• intravenous leiomyomatosis
  1 June 2005

  Intravenous leiomyomatosis (IVL) is a rare smooth-muscle proliferation that is of special interest because of its quasi-malignant behavior.
  Intravascular leiomyomatosis (IVL) is characterized by the presence of smooth muscle in venous and lymphatic spaces within the myometrium.
  Although the intravascular component usually consists solely of typical smooth muscle or variants of smooth muscle differentiation, some cases have been reported in which the intravascular component also included (...)

• adamantinoma of long bones
  12 December 2003

  Osteofibrous dysplasia-like adamantinomas occur in children and adolescents and behave relatively benign, whereas classic adamantinomas predominate in adults and have a more aggressive clinical course.
  Adamantinoma is most frequently seen in tibia and has been reported to involve the adjacent fibula occasionaly.
  Variants
  osteofibrous dysplasia-like form with scattered epithelial elements
  Types
  classic form with abundant epithelium
  dedifferentiated adamantinoma with revertant (...)
