Melaocytes make pigment, transfer to keratinocytes.
This picture is prolly post-inflamatory hypopigmentation. Melanytes are destroyed or brought further into the dermis.

Q

define atrophic

A

2ndary lesion: Emaciated or thinned (example: striae) (thin skin…stria - can be caused by constant use of steroidal creams)

35
Q

define verrucous

A

2ndary lesion: WART Characterized by velvety or roughened wart-like change (example: verruca vulgaris)

36
Q

define scarred

A

2ndary lesion: Showing fibrous connective tissue replacement; a result of dermal injury (example: keloid)

37
Q

in what layer of skin are Langerhans cells, melanocytes, and Merkel cells found?

A

in the epidermis

Langerhans cells (antigen-presenting cells)
Melanocytes (pigment-forming cells)
Merkel cells (sensory cells)
38
Q

What does this show?

A

Epithelium = barrier that protects from outside…any lining that touches outside

Called the epidermis in skin.
Upper layer = stratum corneum, dead cells.
Stem cells at base of epidermis, move up until evetuily die and become part of statum corneum

Bottom part is all dermis: soft tissue/connective tissue/ stroma (contains blood vessels), microlysacharides make up white space…
Bottom central cluster = ecrine sweat gland…
Also nerves, fat, smooth muscles, not seen here.
Melanocytes are right along the basal layer of epidermis (bottom of purple layer…)

Neoplasms try to resemble one of these types of skin.

39
Q

Name the circles and the squiggles:

A

Circules = hair follicles. White around them = fat

Squiggle = erector pili smooth muscle

40
Q

Where does most pigment reside?

A

in the epithelial cells, not in melanocytes

41
Q

What does this show?

A

THICK SKIN – hyperplasia of epidermis. (Lichenified, vernicus skin would look like this…describe as scaly or hyperkkeratosis)

42
Q

What does this show?

A

No epidermis. Pink = fiber/protein/exudate…mixed with neutrophils (dots)
