It's also known as "tree man" disease.
Bajandra first noticed the peculiar branch-like growths on his hands when he was 10 years old and tried cutting them off by himself, his doctor, Samanta Lal Sen, told CNN.
Now he's 30 and has one of the most severe cases of the condition ever recorded.
"This is one of the most rare cases of disease that I have seen in Bangladesh, even in the world", said Lal Sen, the chief-coordinator of the surgery at Bangladesh's state-run Dhaka Medical Hospital.
