The condition usually has an onset of between the ages of 1–20, but can occasionally present in middle-age. It is named after the physicians who first documented it, Felix Lewandowsky

 and Wilhelm Lutz.

Genetic cause

The cause of the condition is an inactivating mutation in either the EVER1 or EVER2 genes, which are located adjacent to one another on chromosome 17. The precise function of these genes is not yet fully understood, but they play a role in regulating the distribution of zinc in the cell nucleus. It has been shown that zinc is a necessary cofactor for many viral proteins, and that the activity of EVER1/EVER2 complex appears to restrict the access of viral proteins to cellular zinc stores, limiting their growth.

Diagnosis

Clinical diagnostic features are lifelong eruption of pityriasis versicolor-like macules, flat wart-like papules 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. The benign form of EV presents with only flat, wart-like lesions over the body, whereas the malignant form shows a higher rate of polymorphic skin lesions and development of multiple cutaneous

 series "My Shocking Story" (Extraordinary People on UK's Five) in the episode "Half Man Half Tree". And then on August 12, 2008, Dede Koswara's story was the subject of an ABC's Medical Mystery episode entitled "Tree Man".

On 26 August 2008, Dede returned home following surgery to remove 6 kg (13 lb) of warts from his body. The surgery consisted of three steps:
  • Removal of the thick carpet of warts and massive horns on his hand.
  • Removal of the smaller warts on his head, torso, and feet.
  • Covering of the hands with grafted skin.


In all, 95% of the warts were removed. The surgery was documented by the Discovery Channel and TLC in the episode "Treeman: Search for the Cure." However, his warts have returned and it appears he will need two surgeries a year for the rest of his life to keep them at bay. 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.

In 2009 the Discovery Channel episode "Treeman Meets Treeman" reported on another Indonesian man, from the same region as Dede, who also has the disease and was given a similar treatment for it. Thus far his treatment seems to have worked better.

According to The Jakarta Post, Dede underwent the first of a series of new surgical procedures to remove the regrown warts in the spring of 2011. Surgery has however proven to be a temporary solution for Dede as the warts continue to reemerge. He has thus undergone three surgical operations since his major surgery in 2008, which was covered by the Discovery channel. At the end of December 2010, two doctors from Japan, affiliated with the Japanese Society for Complementary and Alternative Medicine came and brought Dede alternative medicine in powder form, made from coix seeds. The medicine is still undergoing a lab test.
