Multiple Choice Questions MCQ

Question 11# Print Question

With regard to the adductor compartment of the thigh, which of the following is not true?

A. The femoral artery and profunda femoris artery are separated by adductor longus at the level of the middle of the thigh

B. Adductor magnus inserts on the medial border of the tibial plateau

C. The femoral artery becomes the popliteal artery at the adductor hiatus in adductor magnus

D. Adductor magnus arises from both the posterior and anterior aspects of the ischium

E. Adductor brevis arises from the inferior ramus of the pubis

Question 12# With regards to actinic keratoses, which is false?
A. Typical histologic features include a background of elastosis
B. They can be treated using topical 5-fluorouracil
C. They can be treated using topical diclofenac
D. They can be treated using cryotherapy
E. They should always be treated with wide local excision
They should always be treated with wide local excision. E is false. Actinic (solar) keratoses are premalignant lesions related to ultraviolet sun exposure and predispose particularly to SCC. Numerous topical treatments can be used successfully. Surgery is reserved for lesions suspicious of malignancy, for biopsy, or for especially symptomatic lesions that are keratotic. If excision is undertaken, the margins should be minimal and not wide to allow an accurate histopathological diagnosis prior to planning further treatment.

Question 13# Which of the following is not true in relation to the femoral triangle?
A. The inguinal ligament forms the base
B. The lateral border of adductor longus forms the medial side
C. The medial border of tensor fascia lata forms the lateral side
D. The femoral artery and vein lie in front of the fascia covering iliopsoas and the femoral nerve lies behind it
E. At the apex, four vessels and two nerves pass into the adductor canal of Hunter
The medial border of tensor fascia lata forms the lateral side. This statement is incorrect; the lateral border of the femoral canal is the sartorius muscle. While some authorities consider that the medial border of adductor longus forms the medial side, they are in the minority. At the apex, the femoral A&V, profunda femoris A&V, saphenous N. and N. to vastus medialis enter Hunter’s canal. The femoral artery passes from the midpoint of the base of the triangle to the apex.

Question 14# When biopsying melanoma:
A. Incision biopsy is absolutely contraindicated
B. Punch biopsy is an absolute contraindication
C. Incisional biopsy worsens the prognosis
D. A suspicious subungual lesion should be biopsied with a punch or incisional technique
E. None of the above
A suspicious subungual lesion should be biopsied with a punch or incisional technique.

Question 15# The following predispose to mesenchymal neoplasia except:
A. Tuberous sclerosis
B. HIV
C. Familial lipomatosis
D. Megavoltage irradiation
E. Arthrogryphosis congenita multiplex
Arthrogryphosis congenita multiplex. Anthrogryphosis is not associated with mesenchymal tumours - all the others are. HIV is associated with cutaneous (Kaposi) sarcoma. Tuberous sclerosis is associated with angiofibromas and hamartomas as well as lipomas. References: 1. Gnepp DR. Diagnostic surgical pathology of the head and neck, 2nd ed.

Question 11# With regard to the adductor compartment of the thigh, which of the following is not true?
A. The femoral artery and profunda femoris artery are separated by adductor longus at the level of the middle of the thigh
B. Adductor magnus inserts on the medial border of the tibial plateau
C. The femoral artery becomes the popliteal artery at the adductor hiatus in adductor magnus
D. Adductor magnus arises from both the posterior and anterior aspects of the ischium
E. Adductor brevis arises from the inferior ramus of the pubis
Adductor magnus inserts on the medial border of the tibial plateau. B is incorrect. The adductor magnus arises from both aspects of the ischium and inserts into the superior border of the medial condyle of the femur and also the gluteal tuberosity of the posterior femur. The hamstrings lie laterally to the adductor and insert into the tibia. The femoral artery and profunda femoris artery are separated by the medial border of adductor longus. The profunda lies on the anterior aspect of adductor brevis and posterior to vastus medialis at this point.
