  calcifying fibrous pseudotumor PO
  Definition: Calcifying fibrous tumor (CFT) is a rare benign mesenchymal tumor composed of hyalinized fibrous tissue with interspersed bland fibroblastic spindled cells, scattered psammomatous, and/or dystrophic calcifications and variably prominent mononuclear inflammatory infiltrate. CFTs show a predilection for the abdominal cavity and soft tissue.

  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 (...)

  nuchal fibroma ; collagenosis nuchae, nuchal fibrocartilaginous pseudotumor, nuchal fibroma PO
  Definition : A nuchal-type fibroma is a rare, benign fibrous tumour that typically occurs in the posterior neck along the midline, but can occur in extra-nuchal locations, most commonly in the back, shoulder and face.
  Nuchal-type fibroma (NTF ) is a paucicellular, CD34+ fibrous tumor with fat entrapment, which may occur in both nuchal and extranuchal locations and in association with (...)

  AAMs, ’aggressive’ angiomyxoma; deep aggressive angiomyxoma PO
  Definition: Aggressive angiomyxoma (AA) is a distinctive, locally aggressive, fibromyxoid tumor of the pelvic and genital soft tissues.
  Aggressive angiomyxoma is an infiltrative spindle cell neoplasm arising in the soft tissues of the lower genital tract, perineum and pelvis; approximately 30% recur locally but distant metastasis is exceptionally rare

  PO
  Digital cases
  JRC:3546 : angiomyofibroblastoma of the thigh.
  JRC:14780 : vulvar angiomyofibroblastoma.
  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.

  PO
  Definition: Cellular angiofibroma is a rare benign mesenchymal tumour of middle-aged adults. This tumour is usually located in the vulvovaginal or inguinoscrotal region.

  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).
