The surgery was documented by the Discovery Channel and TLC in the episode "Treeman: Search for the Cure". However, his warts returned and he was thought to require two surgeries per year for the rest of his life in order to manage the warts. The Discovery Channel funded a blood analysis and found he lacked an immune system antigen to fight yeast infection. He was offered to have more tests run to determine whether it is treatable, and the doctor was fairly optimistic, but he refused the treatment.According to The Jakarta Post, Koswara underwent the first of a series of new surgical procedures to remove the regrown warts in the spring of 2011. Surgery had, however, proven to be a temporary solution for Koswara, as the warts continued to re-emerge. He had thus undergone three surgical operations since his major surgery in 2008. At the end of December 2010, two doctors from the Japanese Society for Complementary and Alternative Medicine brought him a drug made from Jobs tears. The medicine was still undergoing lab tests as of 2016.Koswara died on 30 January 2016 at Hasan Sadikin Hospital, Bandung, from the complications related to his condition.In 2009, the Discovery Channel episode "Treeman Meets Treeman" reported on another Indonesian man, from the same region as Koswara, who also has the disease and was given a similar treatment for it. His treatment seemed to have worked better. Omar Tamim
In 2013, one case of epidermodysplasia verruciformis was reported in Iraq. No treatment was given since the condition was initially misdiagnosed.
Epidermodysplasia verruciformis (EV), also known as treeman syndrome, is an extremely rare autosomal recessive hereditary skin disorder associated with a high risk of skin cancer. It is characterized by abnormal susceptibility to human papillomaviruses (HPVs) of the skin. The resulting uncontrolled HPV infections result in the growth of scaly macules and papules resembling tree bark, particularly on the hands and feet. It is typically associated with HPV types 5 and 8, which are found in about 80% of the normal population as asymptomatic infections, although other types contribute less frequently, among them types 12, 14, 15 and 17 (which are occasionally referred to as the beta papillomaviruses).The condition usually has an onset of between the ages of one and 20 but it can occasionally be present in middle age. The condition is also known as Lewandowsky–Lutz dysplasia, named after the physicians who first documented it, Felix Lewandowsky and Wilhelm Lutz. Signs and symptoms
Clinical diagnostic features are lifelong eruptions of pityriasis versicolor-like macules, flat wart-like papules, one to many cutaneous horn-like lesions, and development of cutaneous carcinomas.Patients present with flat, slightly scaly, red-brown macules on the face, neck, and body, recurring especially around the penial area, or verruca-like papillomatous lesions, seborrheic keratosis-like lesions, and pinkish-red plane papules on the hands, upper and lower extremities, and face.
