The 37 year old entered an Indonesian hospital because of the huge tree-like growths that had encased his limbs for 20 years.
But an X-ray quickly revealed that the immune deficiency stopping him fighting the warts had also allowed a potentially deadly TB infection to take hold.
Dr Rachmat Dinata, leading the team treating Dede at the Hasan Sadikin Hospital in Bandung, West Java, said: "Five years from now, he would have been dead.
"He had lots of very active bacteria in his lungs. If he hadn't come here, and instead had lived his life as he had, with bad food and not enough of it, then the disease would have spread quickly."
However, intensive treatment has allowed Dede to beat the infection since arriving in hospital in January.
Dr Dinata said: "After three months treatment we have done an X-ray to check. His lungs are clear."
Dede's ordeal began when he was 15 and cut his knee in an accident. A small wart developed on his lower leg and spread uncontrollably.
"The warts began appearing everywhere," he told the Telegraph.
Eventually he had to give up work as a builder. His wife of ten years left him as it became impossible for him to support her and their two children.
Late last year, however, Dede's plight was highlighted on Telegraph.co.uk and in a Discovery Channel documentary.
The documentary team took American dermatology expert Dr Anthony Gaspari to Indonesia to see if he could find a cure.
Dr Gaspari, of the University of Maryland, is now liaising with the team treating Dede in Bandung.
He concluded Dede's affliction was caused by the Human Papilloma Virus (HPV), a fairly common infection usually causing only small warts.
Dede, however, has an extremely rare immune system deficiency, leaving his body unable to contain the warts. The virus was able to "hijack the cellular machinery of his skin cells", ordering them to produce massive amounts of the substance causing tree-like growths known as "cutaneous horns".
Dr Dinata revealed the immune deficiency is so severe they have to be extremely wary of transmitting infections to Dede.
He said: "He is like an HIV patient, but he is negative. Because his immunity system is so weak, it's easy for other infections to enter his body. We have to be very careful around him if we have flu."
Four major operations have removed most of Dede's growths, including 4lbs of warty tissue from his feet alone. His hands are still massive clumps, but he can now use them for the first time in more than a decade.
He enjoys doing sudokos, but it can take him several days to complete one – not only are the puzzles challenging in themselves, the remaining growths on his hands still make it difficult for Dede to use a pen.
Dede has three more months of treatment to go before doctors think he will be fully cured, and is tentatively making plans for the future.
He told the Telegraph: "If all the growths are gone, I want to work again. If I had some seed money I would like to open a small business in my village, selling whatever I could."
He also laughed as he confirmed that he would also like to remarry.
"Yes I would like to get married again."
