Usnea is a genus of fruticose lichens in the large family Parmeliaceae. The genus, which currently contains roughly 130 species, was established by Michel Adanson in 1763. Species in the genus grow like leafless mini- shrubs or tassels anchored on bark or twigs.
Usnea sphacelata is a species of saxicolous (rock-dwelling), fruticose lichen in the large family Parmeliaceae. It is found in both polar regions of Earth , as well as in southern and northern South America and in New Zealand.
The lesion then ulcerates and may become secondarily infected with bacteria. In many species (for example, L. major) the lesion often spontaneously heals with atrophic scarring. In some species (for example, L. braziliensis) the lesion may spontaneously heal with scarring, but then reappear elsewhere (especially as destructive mucocutaneous ...
Dolichousnea was originally circumscribed as a subgenus of the large genus Usnea, by Japanese lichenologist Yoshihito Ohmura in 2001. He considered that it was possible to treat the three taxa as a genus, but thought it more suitable to treat Dolichousnea at the rank of subgenus, because the taxa have the synapomorphies of the genus Usnea: a fruticose thallus, a central cartilaginous axis ...
This is a shortened version of the twelfth chapter of the ICD-9: Diseases of the Skin and Subcutaneous Tissue. It covers ICD codes 680 to 709. The full chapter can be found on pages 379 to 393 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
Usnea subcomplecta is believed to be endemic to the Galápagos Islands, where it is a common species. It thrives in the humid and upper transition zones , as well as in some high-altitude dry zones. The lichen is usually found in open, often disturbed habitats such as farmland areas, fence posts, and trees along pastures.
Europe and other parts of the world use the ICD-10. The root codes for ICD-10 and ICD-10-CM are the same, making it helpful for locating codes for general body systems and disease processes. [2] [3] In ICD-11 the search and coding of any disease, including rare ones is done via the ICD-11 website. [4]
Blueberry muffin lesions in the neonate indicate the prolongation of dermal extramedullary hematopoiesis outside of the gestational period. [ 3 ] The blueberry muffin rash was originally considered pathognomonic of congenital rubella , but it is now considered to be potentially associated with many other intrauterine infections, hematologic ...
