–Plaques – Large, measure greater than 5mm, often formed by a confluence of papules. i.e. psoriasis
•Cysts – are enclosed cavities with a lining that can contain a liquid or semisolid material. i.e. sebaceous cyst.
•Telangiectasia – is a dilated superficial blood vessel.
•Bullae - are large vesicles (equal to or greater than 6mm). i.e. pemphigus
plaques, cysts, telegiectasia, and bullae are examples of (primary/secondary) lesions

what type of carcinoma
basal cell.
- MC form of skin cancer, usually occurs in sun damaged skin.
- Can cause a lot of local damage, but typically does not metastasize.
- Smooth, round, pearly borders with central pallor or ulcer.
- Recurrent bleeding, failure to heal.
- Tx - excision
what type of cancer
squamous cell.
- 2nd MC form of skin cancer.
- Sun Exposed areas. Can metastasize.
- Ulceration, scabbed over, recurrent bleeding, becomes deeper, ulcerated over time.
Treatment – excision
what type of cancer
malignant melanoma.

- Often seen in non-sun exposed areas.
- Metastasizes early and widely.
- Treatment – need wide excision by a professional (dermatologist or surgeon) if melanoma is suspected.
