Psoriatic nails are characterized by a translucent discolouration in the nail bed that resembles a drop of oil beneath the nail plate. [2] Early signs that may accompany the "oil drop" include thickening of the lateral edges of the nail bed with or without resultant flattening or concavity of the nail; separation of the nail from the underlying nail bed, often in thin streaks from the tip-edge ...
Severe congenital onychogryphosis affecting all twenty nailbeds has been recorded in two families who exhibit the dominant allele for a certain gene. [6] [7]Congenital onychogryphosis of the fifth toe (the baby, little, pinky or small toe) is fairly common, but asymptomatic and seldom brought to the attention of medical professionals.
Onychorrhexis also known as brittle nails, is brittleness with breakage of fingernails or toenails. Paronychia is a bacterial or fungal infection where the nail and skin meet. Koilonychia is when the nail curves upwards (becomes spoon-shaped) due to an iron deficiency. The normal process of change is: brittle nails, straight nails, spoon-shaped ...
When the condition occurs on all the twenty nails of the fingers and toes, it is known as twenty-nail dystrophy, most evident in childhood, [4] favoring males. [ 2 ] [ 5 ] Trachyonychia causes the nails to become opalescent, thin, dull, fragile, and finely longitudinally ridged, and, as a result, distally notched. [ 6 ]
Dyskeratosis congenita (DKC), also known as Zinsser-Engman-Cole syndrome, is a rare progressive congenital disorder with a highly variable phenotype. [3] The entity was classically defined by the triad of abnormal skin pigmentation, nail dystrophy, and leukoplakia of the oral mucosa, and myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML), but these components do not always occur. [3]
Median nail dystrophy, also known as dystrophia unguis mediana canaliformis, median canaliform dystrophy of Heller, [1]: 657 and solenonychia consists of longitudinal splitting or canal formation in the midline of the nail, a split which often resembles a fir tree, occurring at the cuticle and proceeding outward as the nail grows.
At present, the specific cause of shell nail syndrome is unknown. American doctors Chalmers E. Cornelius and Walter B. Shelley first characterized the morphogenesis of the condition in a 1967 Archives of Dermatology publication, stating: "this disorder can be explained by the production of a curved nail by a normal nail matrix which grows out as a shell to thus form a roof over the atrophic ...
Nail–patella syndrome is a genetic disorder that results in small, poorly developed nails and kneecaps, but can also affect many other areas of the body, such as the elbows, chest, and hips. The name "nail–patella" can be very misleading because the syndrome often affects many other areas of the body, including even the production of ...
