• giant cell angiofibroma
  11 October 2005

  Definition: Giant cell angiofibroma is a phenotypic variant of solitary fibrous tumor (SFT).
  Giant cell angiofibroma seems most often to arise in the head and neck region (predominantly orbit) of adults and which, with the passage of time.
  It may well prove to be a variant of solitary fibrous tumour characterized by prominent multinucleate giant cells and lipofibromatosis.
  It is a rare tumour occurring predominantly in the hands or feet of infants and young children.
  it shows a high (...)

  Definition: Solitary fibrous tumor is a spindle cell tumor first described in the pleura, but also found in multiple extrathoracic sites including the meninges, orbit, nasal and paranasal sinuses. Solitary fibrous tumor represents a spectrum of mesenchymal tumors, encompassing tumors previously termed hemangiopericytoma, which are classified as having intermediate biological potential (rarely metastasizing) in the 2002 World Health (...)

  Definition: Angiomyofibroblastoma shows a predilection for the vulvovaginal region during the reproductive years but which may also occur in the inguinoscrotal region in me.
  Angiomyofibroblastoma is distinguished from aggressive angiomyxoma by its circumscription, greater cellularity, greater vascularity and virtual absence of recurrent potential.

  Definition : Juxta-articular myxoma is essentially morphologically identical to cellular myxoma but involves subsynovial tissue, usually of larger joints, and may quite often recur locally.

  Case 38 : Sclerosing epithelioid fibrosarcoma
  Definition: Sclerosing epithelioid fibrosarcoma is a rare variant of fibrosarcoma. It is a mesenchymal neoplasm composed of round to oval cells dispersed in a nestlike or cordlike distribution on a highly collagenous tissue background and is now recognized as a distinct clinical entity.
  Sclerosing epithelioid fibrosarcoma is a rare and poorly recognized but distinct variant of fibrosarcoma (ICD-O code 88 10/3).

• malignant mesenchymoma
  27 April 2009

  Malignant mesenchymoma has now virtually fallen into disuse, since the majority of sarcomas showing two or more lines of differentiation would nowadays be recognized, in most cases, as examples of tumours such as dedifferentiated liposarcoma or malignant peripheral nerve sheath tumour with heterologous elements.
  There do exist exceedingly rare sarcomas showing two lines of differentiation which would not fit into the above categories, but these do not seem to form a clearly definable or (...)
