Overview

Neurofibromatosis type 1 was fully described in1882 by German pathologyst Friedrich von Recklinghausen, for which the disorder was eponymously named after him (von Recklinghausen disease), although the recognition of individuals with this phenotype probably dates back from the Hellenistic era.[1]

Discovery

Cultural history of Neurofibromatosis type 1

  • Probably the most famous case of neurofibromatosis type 1 was described in 1888, in England, with Joseph Merrick, the "elephant man". This man had a difficult life, were he was cruely exhibited in circuses as a phenomenon. Joseph was born as a healthy child in 1862, but started to develope typical characteristics of the disease at age 2.[11] By age 22, Merrick presented dysmorphic facies, a big head-size, skin and bone deformities, but surprisingly, no cognitive impairment. He quoted:

"The deformity I am exhibiting now is because an elephant scared my mother; she walked down the street as a procession of animals paraded. A huge crowd gathered to watch them, and unfortunately they pushed my mother under the feet of an elephant. She was very scared. She was pregnant with me, and this misfortune was the cause of my deformity".

"Is true that my form is something odd, but blaming me is blaming God; could I create myself anew would not fail pleasing you.If I could reach from pole to pole or grasp the ocean with a span, I would be measured by the soul. The mind´s the standard of the man.[12]

  • This patient was the ispiration for the 1980 movie "The Elephant Man", by david Lynch.

Impact of Neurofibromatosis type 1

Society's acceptance and understanding for neurofibromatosis type 1 has changed drastically over the time; from beign a so-called a "montruous disease", to a well known entity now in day, compassion have grown for those individuals suffering from this condition thanks to the many research behind its behavior and characteristics. Advances in its treatment have made a great impact in the natural history of this disease, decreasing mortality and now focusing on a more multidysciplinary management.[5]
