Hypertrophic tumor

The unfortunate man shown in this 1870 photograph was suffering from a "hypertrophic" tumor of the head caused by neurofibromatosis - the same genetic disorder that affected John Merrick, the "Elephant Man." What had started off at birth as a small bump on the temple had grown to obscure much of the right side of the man's face by the time he turned 30. What treatment did his ophthalmologist recommend? None at all.
