• colorectal hyperplastic polyp
  11 March 2005

  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 (...)

• seminoma
  28 April 2005

  seminoma of the testis, testicular seminoma; pure seminoma ; classical seminoma WKP
  Definition: Seminoma is a germ cell tumor of the testicle or, more rarely, the mediastinum or other extra-gonadal locations. It is a malignant neoplasm and is one of the most treatable and curable cancers, with a survival rate above 95% if discovered in early stages.
  Classic seminoma, far and away the most common of the two categories.
  Testicular seminoma originates in the germinal epithelium of the (...)

• sacrococcygeal teratoma
  18 July 2004

  Sacrococcygeal teratoma (SCT) is the most common tumor of the newborn with an incidence of 1 in 35,000 to 40,000 live births.
  In the newborn, the sacrococcygeal site is located at the base of the tailbone (coccyx), is the most common location of teratomas in newborns.

  JRC:4371 : Juxtacortical chondroma.
  Clinical synopsis
  Soft tissue chondroma is a rare benign cartilage lesion that has also been called extraskeletal chondroma or chondroma of soft parts. It occurs most commonly in the soft tissues of the hands and feet. The majority are located in the hands and wrists, especially in the fingers. The tumor is typically associated with a tendon, tendon sheath or joint capsule.
  They can be seen in patients of any age, but most are (...)

• ovarian dysgerminoma
  22 December 2005

  Definition: a primitive germ cell tumor, similar to testicular seminoma. A dysgerminoma is a type of germ cell tumor; it usually is malignant and usually occurs in the ovary.
  Dysgerminoma (seminoma) has fibrous septae infiltrated by lymphocytes. It also tends to arise out of intratubular germ cell neoplasia. If syncytiotrophoblast is present, it may have elevated hCG.

• osseous PEComa
  18 November 2010

  PEComa in bone
  PEComas other than angiomyolipoma, lymphangioleiomyomatosis, and clear cell sugar tumor of the lung are relatively rare, and PEComas presenting in bone are especially rare.
  Both the primary and metastatic PEComas can present in bone, although both are rare.
  It may be suggested that primary PEComa of bone tends to involve lower extremities.
  Histologically, they show similar cytomorphology, nested architecture, and characteristic vessels as PEComas at other sites.
