Nevus Congenital giant pigmented nevus; Giant hairy nevus
A bathing trunk nevus is a darkly pigmented, disfiguring, often hairy patch of
skin (nevus) present at birth, which may cover an extremely large area of the
body. Sometimes the nevus covers most of the trunk, the upper arms, and
thighsbathing trunk nevi are thought to be caused by spontaneous mutations or
other events during fetal development, but in some families, the frequent
appearance of these lesions suggests that they may be genetically inherited.
They may be associated with other birth defects.
The surface texture may vary from smooth to warty, and the color varies from
brown to bluish black. Bathing trunk nevi may cause emotional problems
because of their appearance.
They can also be dangerous. The nevus has a high risk of developing into
melanoma (a type of skin cancer). The risk is thought to be between 3% and
7%.
The hallmark of this condition is a darkly pigmented lesion covering an
extensive area of the trunk or extremities. The nevus may contain hair, and its
surface texture may vary from smooth to warty and the color from brownish to
bluish black.
Smaller lesions may exist near the margins of the primary lesion.On rare
occasion, bathing trunk nevi are associated with a condition called
leptomeningeal melanocytosis (growth of pigment-producing cells in the head),
which can produce hydrocephalus, motor abnormalities, and seizures.
Bathing trunk nevi can become melanoma. They can also be associated with
spina bifida, meningocele, other nevi, lipomas, and neurofibromatosis.
Depression and other emotional problems may occur due to social difficulties
related to bathing trunk nevi.
Nictitation Winking.
Noma Decancrum oris; Gangrenous stomatitis Noma is a disorder that destroys
mucous membranes of the mouth (and later, other tissues) that occurs in
malnourished children in areas of poor cleanliness.Noma is a disorder that
causes sudden, rapidly progressive tissue destruction. The mucous membranes
(e.g., gums, lining of the cheeks) become inflamed and develop ulcers. The
infection spreads from the mucous membranes to the skin. The tissues in the
lips and cheeks die. Rapid, painless tissue breakdown continues and this
gangrenous process can destroy the soft tissue and bone. Noma can also affect
the mucous membranes of the genitals, spreading to the genital skin (this is
sometimes called noma pudendi).This disorder occurs primarily in young,
severely malnourished children 2-5 years of age. Often they have had a
preceding illness such as measles, scarlet fever, tuberculosis, malignancy, or
immunodeficiency. It is seen in areas of poor cleanliness and sanitation. The
exact cause is unknown, but may be bacterial (fusospirochetal organisms). Risk
factors include Kwashiorkor and other forms of severe protein malnutrition, poor
sanitation and poor cleanliness, disorders such as measles or leukemia, and
living in an underdeveloped country.the ulcers develop a foul-smelling drainage,
causing breath odor and an odor to the skin .eventual destruction of the bones
around the mouth cause deformity and loss of teeth
Noxious effluvia To breathe out. Hence: To emit, as vapor; to send out, as an odor; to
evaporate; as, the earth exhales vapor; marshes exhale noxious effluvia.
Nyctalopia Night blindness, impaired vision in dim light and in the dark, due to impaired
function of certain specialized vision cells (the rods) in the retina.
