Biologic progression of melanoma

Melanocyte → nevus → dysplastic nevus → меlanoма “ in situ” → superficial spreading melanoma →

nodular melanoma → metastatic melanoma

Malignant Melanoma: Risk Factors

Age > 40 yr. Race: whiteSun exposure: UVA, UVB Hereditary factors: “melanoma families“, atypical mole syndrome or dysplastic nevus syndrome Trauma of moles, Giant congenital neviOncogene mutations

Screening:

Self-Examination for Melanoma:

examine your body front and back in the mirror, arms and palms, legs and feet, neck and scalp – If you have any doubt about a mole, see a dermatologist-oncologist

(American Academy of Dermatology)

Professional education:

students family doctors dermatologists surgeons cosmetologists morphologists oncologists ! nurses

ABCD-test

ABCD rules for diagnosis of melanoma:

Epiluminescence microscopy (dermatoscopy)

Epiluminescence microscopy (ABCD)

Diagnostics system MoleMax:

Growth patterns of melanoma:

superficial spreading melanoma – 70% nodular melanoma – 15-20% lentigo maligna melanoma – 4 -10% acral lentigo-melanoma – 2-8% amelanotic melanoma – 5%

Thickness of melanoma

TNM:

T1 < 1 mmT2 1-2 mmT3 2-4 mmT4 > 4 mm

Radial growth phase

Vertical growth phase

Evaluation for Metastasis: N0-3, M0-1

Regional Lymph Nodes: N0 – no metastasis,N1 – one lymph node with metastasis,N2 – 2-3 lymph nodes with Mts.,

N3 – 4 and > metastatic lymph nodes. Distant Metastasis: M0 – no metastasis,M1a: Mts in subcutaneous tissue, M1b: Mts in lung,M1c: Mts in other visceral organs (brain, liver, etc)

Nodular Melanoma Т4bNхM0

Biopsy techniques

For cytologic diagnosis:- fine-needle aspiration,- superficial scraping.

For histologic diagnosis:- complete excision
