Patients with multiple nevi Flashcards
Atypical nevi. Indicator, precursor or simulator?
Indicator
BAP1 1 inactivation syndrome
mutation pap 1 gene
multiple dermal nevi
ocular melanoma
pancreas Ca
Typical and atypical nevi may indicate increased melanoma risk
T
Can you tell from morphology in which nevus the melanoma will develop
No
In Australia, annual risk of melanoma in nevus
1:200 000
In Australia annual risk of melanoma on face
1:8000
short term monitoring of single lesions
Picky atypical nevi
Any change results in excision - 3/12 months
Long term monitoring of multiple lesons
Monitor all nevi
Only significant change results in excision 6-12 monts
