A

Acral Melanoma

25
Q

Red flags for melanomas (6).

A
  1. New mole appears postpuberty that changes in color, shape, or size
  2. Longstanding mole changes in color, shape, or size
  3. Mole has three or more colors, or has lost its symmetry
  4. Mole itches or bleeds
  5. New persistent lesion that grows, is pigmented, or vascular in appearance
  6. New pigmented lesion in or under a nail
26
Q

Which subtype of melanoma: superficial spreading, nodular, lentiginous, or acral?

Squamous cell carcinoma accounts for _____% of all cutaneous malignancies.

A

20%

28
Q

What is the 5 year survival rate of merkel cell carcinoma?

A
