A 16-year-old male presented with a 3-month history of an asymptomatic, enlarging conjunctival lesion. An excisional biopsy was performed and histologic and immunohistochemical examination showed characteristic features of a peripheral primitive neuroectodermal tumour (PNET) adjacent to a benign compound naevus.

Is directed donation misguided?

The worldwide shortage of organs and tissue for transplant has led to many ethical discussions involving restrictions concerning organ and tissue donation, including living donations and payment for donation.
