Conservative treatment
Excisional biopsy with wide margins

Question 11 - You have excised an irregular pigmented lesion from chest of a 50-year-old woman. The pathology report states that the lesion is melanoma, Clark’s level III. This means that the lesion:

Has invaded into the reticular dermis
Has invaded into the subcutaneous fat
Has not crossed the basement membrane
Has invaded into the papillary-reticular junction
Has invaded into papillary dermis

Question 12 - A man has a suspected melanoma excised from his back. It appears to be less than 1 mm deep. The smallest margin to plan for excision is:

5 cm
2 cm
1 cm
6 cm
2 mm

Question 13 - This subtype of melanoma is the most aggressive, arising in apparently normal skin or in a nevus, and rapidly becoming a firm, elevated nodule of dense black or brown-black colour. The nodule may have bluish hues, and in 5% of cases may be amelanotic (flesh coloured). This subtype, which comprises 15% of all melanoma cases, can arise at any site in the body. The name of this subtype is:

Superficial spreading melanoma
Nodular melanoma
Lentigo maligna melanoma
Acral lentiginous melanoma

Question 14 - This type of skin lesion is elevated, brown, and has a “stuck on” appearance:

Actinic keratosis
Basal cell carcinoma
Xanthoma
Seborrheic keratosis
Verruca

Question 15 - The following are all types of basal cell carcinoma EXCEPT:

Nodular
Pigmented
Marjolin’s ulcer
Morpheaform

Question 16 - What is the most common tumour of the hand?

Basal cell carcinoma
Giant cell
Osteoma
Ganglion cyst

Question 17 - A 40-year-old woman arrives at her family doctor’s office with concern about a black, bleeding lesion on her left lower leg. She states that it has become enlarged over the past several months and more irregular in appearance. Which of the following is FALSE about melanoma?

Excision is the primary management
Nodular melanoma is the most common
Ulceration is a negative prognostic factor
Family history is a risk factor
The most common site on males is the back

Question 18 - The following are true of the skin lesions EXCEPT:

Actinic keratosis is completely benign with no malignant potential
Nodular ulcerative variant is a type of basal cell carcinoma
Squamous cell carcinoma occurs in primarily sun exposed area of skin
Basal cell carcinoma has a 95% cure rate if lesion is less than 2 cm in diameter

Question 19 - Which of the following is NOT associated with Marjolin’s ulcer?

Basal cell carcinoma
Attenuated burn
Squamous cell carcinoma
Inflammation
Aged scar

Question 20 - Risk factors for developing melanoma include all of the following EXCEPT:

Fair skin
Freckles
African American
Actinic keratosis

Question 21 - A tumour descending into the reticular dermis, but not invading the subcutaneous tissue, would be classified as:

Clarks level I
Clarks level III
Clarks level V
Clarks level IV

Question 22 - Which of the following regarding melanoma is TRUE?

Acral lentiginous is the most common subtype
Breslow’s depth of invasion is a more reliable indicator of prognosis than Clark’s levels.
A Breslow depth of <0.76 mm carries a metastases rate of 25%
Complete excisional biopsy is usually not necessary

Question 23 - The best treatment for the removal of actinic keratoses is:

Surgical excision
Topical chemotherapy
Radiation
Cryotherapy with liquid nitrogen
All treatments are equal efficacy

Question 24 - Which nevus would you most likely remove due to its increased malignant potential?

Compound
Intradermal
Junctional
Large pigmented
None of the above
