Dear Editor – I would like to call to your attention and that of the editors of other medical journals to an uncommon situation that may represent a case of scientific misconduct. During the past years, I have received several “letters to the editor” written by Dr. Viroj Wiwanitkit (Bangkok, Thailand), commenting on my publications on neurocysticercosis. While those letters were not hostile, they included useless comments and were clearly written by a person that is not familiar with this disease.
