Q

Indications for ttt of benign melanoma & its ttt

Study These Flashcards
A

  2. Giant hairy naevi; compound naevus covering larger area of skin
    TTT: medical (quinolones), laser (Q-switched), surgical excision
25
Mention signs of malignant transformation in naevi

26
Mention predisposing factors of malignant melanoma
1. Prolonged exposure to sunlight (UV rays) 2. Inc incidence in albinism, retinitis pigmentosa, rare in negros more c in fair skinned 4. On top of benign lesions (if exposed to chronic irritation)
27

30
Worst type of MM is……, diagnosed by…..
Amelanotic melanoma Dopa reaction test & biopsy
31
Compare clinically bet lentigo maligna & superficial spreading
LM: younger age, MC trunk in males, leg & back in females SS: old ages females, more c on face in sun exposed areas
32
Describe blood spread of MM
MC to lung, high affinity to liver
33
Mentiom INV for MM
Diagnosis: excisional biopsy, safety margin 3mm, should include whole skin & SC tissue forcstaging, paraffin better than frozen Staging isotope scintigraphy for sentinel LN Preop: routine inv
34
In Clark’s classification, levels…..are those of radial growth, levels…..are those of vertical growth
I & II III, IV, V
35
Mention how safety margin is calculated for MM
1 cm if thickness <1mm 2 cm if thickness 1-4mm 3 cm if thickness >4mm
