Q

Keloid

A

Shiny firm overgrowth of scar tissue beyond original scar site, often due to genetic influence and can be itchy or tender, not good to cut off causes scarring and comes back

17
Q

Keloid treatment

A

Only intralesional steroids will help

18
Q

Lipoma

A

Collections of fat under the skin with a soft rubbery texture that grows a few cm in diameter and is unknown cause but suspected to be genetic

19
Q

Lipoma treatment

A

Surgical excision (not covered by insurance completely elective)

20
Q

Epidermal inclusion cyst

A

Mobile subcutaneous nodule often with overlying punctum that does NOT arise from sebaceous glands, have a foul smelling white discharge, sterile and do not require antibiotics

21
Q

Milia

A

Tiny epidermoid cyst often on the face and tends to resolve in infancy but may persist if occur in adulthood

22
Q

Milia treatment

Very easy, pierce the surface, express the contents, and dress

23
Q

Pilar (trichilemmal) cysts

24
Q

A

Slow growing tumor often apeparing after age 50 that must be differentiated from basal cell CA, can be differentiated by location of telangiectatic vessels within valleys between hyperplasic sebacous cells opposed to being bunched up randomly like in basal cell CA

25
Q

Q

A

Involves physician taking tiny shavings off skin from cancer cell site layer by layer until completely removed when measured microscopically to ensure complete excision
