Anatomic and Physiologic changes in the skin from birth to old age Flashcards
causes of hyperpigmentation in pregnant women
increased placental ovarian hormone, MSH reversal, greater estrogen and progesterone sensitivity
dark brown streak that extends from the pubis to the umbilicus/navel, arises during first trimester
linea nigra
“pekas”
Melasma (“mask of pregnancy”)
linear, pink-violaceous atrophic lines that form opposite skin tension lines
striae/stretch marks
red macular or papular telangiectatic puncta with radiating branches and surrounding erythema
spider nevi
caused by increased pressure on legs during pregnancy
varicosities
due to sodium retention with increased capillary permeability
non-pitting edema
small flesh-colored skin tags present more commonly in overweight pregnant women
acrochordon
glandular activity during pregnancy
eccrine: increased
apocrine: decreased
sebaceous: increased
white covering produced that protects the kin of the fetus
vernix caseosa
vernix casesosa dries up and flakes off, leaving skin with intense erythema
erythema neonatorum
marbled skin in the newborn associated with temperature changes
cutis marmorata
puberty vs adolesence
adolescence includes psychological and social maturation
dandruff
seborrheic dermatitis
universal, inevitable change attributed to passage of time manifested primarily by physiologic alterations in sun-protected skin
true/intrinsic ageing
