Figure 5

Case 2 histopathological image of excised lesion of OD, showing characteristics of normal skin. (a) At low magnification, it is impossible to differentiate the sample from another skin sample. Note the anatomical continuum from the left (eyelid hamartoma, L) to the right (conjunctival dermoid, R) and the conjunctival margin of the sample (#). Medium magnification shows pilosebaceous structures () with hair shafts (), sweat glands (S), and adipose lobules (A) on the cutaneous side (b) and conjunctival side (c) of the dermoid. High power aspect highlights differences between the keratinized epidermis (d) and the smooth, non-, or slight-keratinized thinner epidermis of the conjunctival side (e). Haematoxylin and eosin staining. Original magnification ×10 (a), ×40 (b, c), and ×200 (d, e).
