Diseases

Duplication of urethra

Urethral duplication is a rare congenital anomaly with approximately 190 cases described in literature. Most of the reported cases are of incomplete duplications, with complete duplication being rare. This anomaly is most common in males with a few cases having been reported in females.

Dupuytren subungual exostosis

A benign form of slow-growing tumor that develops on the surface of the bones under the nails. The cause of the condition is unknown and it tends to occur in children and young adults. The big toe is the most common digit affected.

Dwarfism

Dwarfism occurs when an individual person or animal is short in stature resulting from a medical condition caused by slow growth. In humans, dwarfism is sometimes defined as an adult height of less than 4 feet 10 inches (58 in; 147 cm).[1] Dwarfism can be caused by more than 300 distinct medical conditions, such that the symptoms and characteristics of individuals with dwarfism vary greatly. Disproportionate dwarfism is characterized by one or more body parts being relatively large or small in comparison to those of an average-sized adult, with growth variations in specific areas being apparent. In cases of proportionate dwarfism, the body appears normally proportioned, but is unusually small.

Dwarfism bluish sclerae

A form of dwarfism that also involves the presence of bluish sclera (due to abnormally thin sclera).

Dyschromatosis universalis hereditaria

Dyschromatosis universalis hereditaria is a rare genodermatosis characterized by reticulate hyper- and hypo- pigmentated macules in a generalized distribution

Dysequilibrium syndrome

A very rare syndrome characterized mainly by mental retardation and nonprogressive incoordination.

Dyserythropoietic anemia- congenital

A very rare genetic blood disorder where abnormal red blood cells are made resulting in anemia. Finger and toe abnormalities are also usually present.

Dyserythropoietic anemia- congenital type 1

Dyserythropoietic anemia, congenital type 1: A very rare genetic blood disorder where abnormal red blood cells are made resulting in anemia. Finger and toe abnormalities are also usually present.

Dysesthetic Vulvodynia

Dysesthetic Vulvodynia: Generalized pain in the vulvar region which can occur intermittently or constantly and has no obvious cause. The pain may be triggered by activities that put pressure on the area such as bike riding, tight clothes or even intercourse.

Dysferlinopathy

Dysferlinopathy (medical condition): An autosomal recessive form of limb-girdle muscular dystrophy where muscle weakness and atrophy is caused by deficiency of the dysferlin protein. There is variation in the degree of muscle involvement and the rate of progression.

Dysfibrinogenemia- familial

Dysfibrinogenemia, familial is a type of familial medication condition that is not common. It is associated with an abnormal fibrinogen. Dysfibrinogenemia, familial involves several types and subtypes including Detroit, Wiesbaden, and Amsterdam dysfibrinogenemia.

Dysgerminoma

Dysgerminoma: A rare form of cancer of the germ cells in the ovary. It is generally asymptomatic in the early stages. Prognosis with treatment is generally quite good.

Dysgnathia complex

Dysgnathia complex: A very rare disorder characterized by a small or absent jaw, ear abnormalities and a small mouth and tongue. The severity and range of symptoms is variable.

Dyskeratosis congenita

Dyskeratosis congenita (DKC, Zinsser-Cole-Engman syndrome), is a rare progressive congenital disorder with a highly variable phenotype. The entity was classically defined by the triad of abnormal skin pigmentation, nail dystrophy, and leukoplakia of the oral mucosa, but these components do not always occur. DKC is characterized by short telomeres. Some of the manifestations resemble premature aging (similar to progeria). The disease initially mainly affects the skin, but a major consequence is progressive bone marrow failure which occurs in over 80%, causing early mortality.

Dyskinesia- drug induced

Dyskinesia, drug induced: Dyskenisia (abnormal movements) caused by the use of certain drugs. The movements are involuntary and purposeless and can involve just about any part of the body e.g. lip puckering and rapid eye blinking. It can be caused by drugs such as neuroleptic drugs and other dopamine antagonists.

Dysmorphism cleft palate loose skin

Dysmorphism - cleft palate - loose skin: A very rare syndrome characterized mainly by facial abnormalities, an opening in the roof of the mouth and loose skin.

Dysmyelination

Dysmyelination (medical condition): Defective formation of or destruction of the myelin sheath around nerves
