1.

Neoplasms, Unknown Primary

Metastases in which the tissue of origin is unknown.

Year introduced: 1987

2.

Fever of Unknown Origin

Fever in which the etiology cannot be ascertained.

Year introduced: 1974(1971)

3.

Lost to Follow-Up

Study subjects in COHORT STUDIES whose outcomes are unknown e.g., because they could not or did not wish to attend follow-up visits.(from Dictionary of Epidemiology, 5th ed.)

Year introduced: 2011

4.

Granulomatous Mastitis

A rare, benign, inflammatory breast disease occurring in premenopausal women shortly after a recent pregnancy. The origin is unknown but it is commonly mistaken for malignancy and sometimes associated with BREAST FEEDING and the use of ORAL CONTRACEPTIVES.

Year introduced: 2011

5.

Receptor Tyrosine Kinase-like Orphan Receptors

A family of cell surface receptors that were originally identified by their structural homology to neurotropic TYROSINE KINASES and referred to as orphan receptors because the associated ligand and signaling pathways were unknown. Evidence for the functionality of these proteins has been established by experiments showing that disruption of the orphan receptor genes results in developmental defects.

Year introduced: 2010

6.

Vulvodynia

Complex pain syndrome with unknown etiology, characterized by constant or intermittent generalized vulva pain (Generalized vulvodynia) or localized burning sensations in the VESTIBULE area when pressure is applied (Vestibulodynia, or Vulvar Vestibulitis Syndrome). Typically, vulvar tissue with vulvodynia appears normal without infection or skin disease. Vulvodynia impacts negatively on a woman's quality of life as it interferes with sexual and daily activities.

Year introduced: 2010

7.

Idiopathic Pulmonary Fibrosis

A common interstitial lung disease of unknown etiology, usually occurring between 50-70 years of age. Clinically, it is characterized by an insidious onset of breathlessness with exertion and a nonproductive cough, leading to progressive DYSPNEA. Pathological features show scant interstitial inflammation, patchy collagen fibrosis, prominent fibroblast proliferation foci, and microscopic honeycomb change.

Year introduced: 2009

8.

Malignant Atrophic Papulosis

Variously described as a vasculopathy, endovasculitis, or occlusive arteriopathy, this condition occurs in a benign cutaneous form and a lethal multiorgan systemic variant. It is characterized by a narrowing and occlusion of the lumen of small to medium-sized blood vessels, leading to ischemia and infarction in the involved organ systems. The etiology and pathophysiology are unknown.

Year introduced: 2008

9.

Colitis, Lymphocytic

A subtype of MICROSCOPIC COLITIS, characterized by chronic watery DIARRHEA of unknown origin, a normal COLONOSCOPY but abnormal histopathology on BIOPSY. Microscopic examination of biopsy samples taken from the COLON show infiltration of LYMPHOCYTES in the superficial EPITHELIUM and the underlying connective tissue (lamina propria).

Year introduced: 2005

10.

Colitis, Collagenous

A subtype of MICROSCOPIC COLITIS, characterized by chronic watery DIARRHEA of unknown origin, a normal COLONOSCOPY but abnormal histopathology on BIOPSY. Microscopic examination of biopsy samples taken from the COLON show larger-than-normal band of subepithelial COLLAGEN.

Year introduced: 2005

11.

Colitis, Microscopic

A condition characterized by chronic watery DIARRHEA of unknown origin, a normal COLONOSCOPY but abnormal histopathology on BIOPSY. This syndrome was first described in 1980 by Read and associates. Subtypes include COLLAGENOUS COLITIS and LYMPHOCYTIC COLITIS. Both have similar clinical symptoms and are distinguishable only by histology.

Year introduced: 2005

12.

Myosin-Light-Chain Phosphatase

A phosphoprotein phosphatase that is specific for MYOSIN LIGHT CHAINS. It is composed of three subunits, which include a catalytic subunit, a myosin binding subunit, and a third subunit of unknown function.

Year introduced: 2004

13.

Vicia faba

A plant species of the genus VICIA, family FABACEAE. The edible beans are well known but they cause FAVISM in some individuals with GLUCOSEPHOSPHATE DEHYDROGENASE DEFICIENCY. This plant contains vicine, convicine, Vicia lectins, unknown seed protein, AAP2 transport protein, and Vicia faba DNA-binding protein 1.

Year introduced: 2003

14.

Poult Enteritis Mortality Syndrome

An acute, transmissible, infectious disease associated with high MORTALITY and MORBIDITY in young turkeys (poults). It is characterized by DIARRHEA; ANOREXIA; growth depression, and immune dysfunction. The cause is unknown but astroviruses (AVASTROVIRUS) and coronaviruses (CORONAVIRUS, TURKEY) have been isolated from diseased poults and are thought to cause the enteritis and increased susceptibility to bacterial infections.

Year introduced: 2003

15.

Schnitzler Syndrome

An extremely rare condition manifested as monoclonal IMMUNOGLOBULIN M dysproteinemia without features of lymphoproliferative disease, but with chronic urticaria, fever of unknown origin, disabling bone pain, hyperostosis, and increased erythrocyte sedimentation rate.

Year introduced: 1998

16.

Hepatitis, Autoimmune

A chronic self-perpetuating hepatocellular INFLAMMATION of unknown cause, usually with HYPERGAMMAGLOBULINEMIA and serum AUTOANTIBODIES.

Year introduced: 1998

17.

Dermatitis, Perioral

A papular eruption of unknown etiology that progresses to residual papular erythema and scaling usually confined to the area of the mouth, and almost exclusively occurring in young women. It may also be localized or extend to involve the eyelids and adjacent glabella area of the forehead (periocular dermatitis). (Dorland, 28th ed)

Year introduced: 1997

18.

Filoviridae Infections

Infections with viruses of the family FILOVIRIDAE. The infections in humans consist of a variety of clinically similar viral hemorrhagic fevers but the natural reservoir host is unknown.

Year introduced: 1995

19.

PrPC Proteins

Normal cellular isoform of PRION PROTEINS encoded by a chromosomal gene and found in normal and scrapie-infected brain tissue, and other normal tissue. PrPC are protease-sensitive proteins whose function is unknown. Posttranslational modification of PrPC into PrPSC leads to infectivity.

Year introduced: 1995

20.

Sweating Sickness

A clinical condition characterized by fever and profuse sweating and associated with high mortality. It occurred in epidemic form five times in the fifteenth and sixteenth centuries in England, first in 1485 and last in 1551, specially during the summer and early autumn, attacking the relatively affluent adult male population. The etiology was unknown.

Year introduced: 1995
