Exam 1 Abnormalities Flashcards
Vitiligo
the complete absence of melanin pigment in the patchy areas of white or light skins on the face, neck, hands, feet, and body folds
Freckles (ephelides)
small, flat macules of brown melanin pigment that occur on sun exposed skin
Mole (nevus)
a clump of melanocytes, tan-to-brown color, flat or raised
Erythema
intense redness of the skin is from excess blood in the dilated superficial capillaries
Cyanosis
is a bluish mottled color from decreased perfusion; the tissues have high levels of deoxygenated blood
Jaundice
a yellowish skin color that indicates rising amounts of bilirubin in the blood
Diaphoresis
profuse perspiration
Edema
is fluid accumulating in the interstitial spaces
Cherry (senile) angiomas
are small ( 1 to 5 mm), smooth, slightly raised bright red dots that commonly appear on the trunk in all adults older than 30 years
Mongolian spot
is a common variation of hyperpigmentation in Black, Asian, American Indian, and Hispanic newborns; is blue-black and usually appears on the sacram
Cafe au lait spot
is a large round or oval patch of light brown pigmentation, which is usually present at birth
Harlequin color change
occurs when a baby is in the side-lying position. The lower half of the body turns red, and the upper half blanches with a distinct demarcation line down the midline
Erythema toxicum
is a common rash that appears in the first 3 to 4 days of life (flea bite or newborn rash)
Acrocyanosis
is a bluish color around the lips, hands, and fingernails, and feet and toenails
Cutis marmorata
is a transient mottling in the trunk and extremities in response to cooler room temperatures
Linea nigra
a brownish black line down the midline of the abdomen; usually found in pregnant women
Striae
are jagged linear “strech marks” of silver-to-pink color that appear during the second trimester
Vascular spider
also called spider angioma. These lesions have tiny red centers with radiating branches and occur on the face, neck, upper chest, and arms
Senile lentigines
are common variations of hyperpigmentation; commonly called liver spots
Keratoses
are raised thickened ares of pigmentation that look crusted, scaly, and warty
Seborrheic keratosis
looks dark, greasy, and “stuck on”
Xerosis
dry skin
Arcochordons
skin tags
Sebaceous hyperplasia
consists of raised yellow papules with a central depression
Annular
lesion that is circular, begins in center and spreads to periphery
Confluent
lesions that run together
Discrete
lesions that are distinct, individual
Gyrate
lesions that are twisted, coiled spiral, snakelike
Grouped
lesions that are clusters
Linear
lesions that are straight
Target
lesions that resemble an iris of an eye
Zosteriform
lesions that are linear arrangement along a unilateral nerve route
Polycyclic
annular lesions grow together
Macule
solely a color change, flat and circumscribed, of less than 1 cm
Patch
macules that are larger than 1 cm
Nodule
solid, elevated, hard or soft, larger than 1 cm. May extend deeper into dermis than papule
Tumor
larger than a few centimeters in diameter, firm or soft, deeper into dermis
Papule
something you can feel caused by superficial thickening in epidermis
Wheal
superficial, raised, transient, and erythematous, slightly irregular shape from edema
Urticaria (hives)
wheal coalesce to from extensive reaction, intensely pruritic
Vesicle
Elevated cavity containing free fluid, up to 1 cm; a “blister”. Clear serum flows if ruptured
Bulla
larger than 1 cm diameter; usually single chambered; superficial in epidermis; thin walled and ruptures easily
Cyst
encapsulated fluid-filled cavity in dermis or subcutaeous layer, tensely elevating skin
