Answer
a=4; b=5; c=6; d=2; e=1; f=3
Explanations:
a is chalazion. Histology of chalazion typically shows chronic inflammation with foreign
body giant cells and empty spaces from lipid removal during tissue processing as in 4.
b shows morphea form of basal cell carcinoma. Histologically this appears as strands
of tumours within abundant fibrous stroma. 4 is the right answer.
c. is Kaposi's sarcoma. Slit-like spaces between spindle shaped cells are characteristic
features. Red blood cells are seen within such spaces as in 6.
d is molluscum contagiosum with the characteristic umbilicated appearance.
Histologically, the infected cells appears pink and contains inclusion bodies as in 2.
e is xanthelasma. Histologically, multiple lipid-filled macrophages are seen. However,
because of tissue processing, the lipid is removed by alcohol leaving clear spaces within
the cytoplasm of the macrophages (as clear cells) similar to 1.
f shows sarcoid infiltration of the face and histologically this appears as non-caseating
chronic inflammation with giant cells as in 3.
