• granulosa cell
  10 May 2012

  Wikipedia
  Definition : A granulosa cell or follicular cell is a somatic cell of the sex cord that is closely associated with the developing female gamete (called an oocyte or egg) in the ovary of mammals.
  In the primary ovarian follicle, and later in follicle development ( folliculogenesis ), granulosa cells advance to form a multilayered cumulus oophorus surrounding the oocyte in the preovulatory or Graafian follicle.
  The major functions of granulosa cells include the production of (...)

  NON-NEOPLASTIC OVARIAN TUMORS
  Types
  ovarian endometriosis (endometrioma of the ovary)
  Endometriosis, or endometrioma, of the ovary may cause an adnexal mass in reproductive age females.
  Pigmented foci on an otherwise normal ovary or a large solitary hemor-rhagic cyst are the gross findings.
  Histologic findings include columnar-to-plump cuboidal epithelium with condensed sub-epithelial stroma, hemosiderin-laden macrophages, fi brosis, and inflammation.
  Rare cases may also contain smooth (...)

  Acute torsion of the ovary
  Synopsis
  Acute torsion of the adnexal structures is an uncommon event but is a surgical emergency.
  The severity of the symptoms varies widely and includes fever, nausea or vomiting, and abdominal pain.
  The correct diagnosis is rarely made preoperatively.
  The preoperative radiograph commonly shows a pelvic mass with a cystic or solid texture, often with thin internal septae, and may simu-late an ovarian mass.
  Because the sigmoid colon cushions and (...)

  Follicular cysts of the ovary; Follicular cyst of ovary; graafian follicle cyst; ovarian functional cyst PO WKP
  Definition: One type of simple cyst, which is the most common type of ovarian cyst, is the follicular cyst of ovary, or "graafian follicle cyst", or "follicular cyst". The follicular cyst of ovary (or ovarian functional cyst) is a type of functional simple cyst, and is the most common type of ovarian cyst.
  Any ovarian follicle that is larger than about two centimeters is (...)

• neonatal ovarian cyst
  24 February 2012

  congenital ovarian cyst; neonatal ovary cyst
  Congenital ovarian cysts may be diagnosed in utero by ultrasound and are associated with resolution; however, their evolution is variable and may require intervention.
  Complications such as torsion and rupture usually occur in cysts larger than 5 cm in diameter.
  Functional ovary cysts
  Cysts that develop in utero are most often lined by luteinized cells, whereas those in older children are more often lined by granulosa cells.
  Premature (...)
