It is characterized by abnormal susceptibility to human papillomaviruses (HPV) of the skin. The resulting uncontrolled HPV infections result in the growth of scaly macules and papules, 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 may also contribute. 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. The cause of the condition is an inactivating HP 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. 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. Other genes have also been rarely been associated with this condition. These include the ras homolog gene family member H. Clinical diagnostic features are lifelong eruptions 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 tumors. Generally, cutaneous lesions are disseminated over the body, but there are some cases with only a few lesions which are limited to one extremity. Treatment No serious treatment against EV has been found yet. Several treatments have been suggested, and acitretin 0.5–1 mg/day for 6 months’ duration is the most effective treatment owing to antiproliferative and differentiation-inducing effects. Interferons can also be used effectively together with retinoids. Cimetidine was reported to be effective because of its depressing mitogen-induced lymphocyte proliferation and Regulatory T cell activity features. A report by Oliveira et al. showed that cimetidine was ineffective. Hayashi et al. applied topical calcipotriol to a patient with a successful result. As mentioned, various treatment methods are offered against EV; however, most important, education of the patient, early diagnosis and excision of the tumoral lesions take preference to prevent the development of cutaneous tumors. Notable cases In March 2007, a Romanian man named Ion Toader was diagnosed with this condition. A patient of dermatologist Carmen Madeleine Curea, his pictures appeared on numerous blogs and Romanian press sources. Curea works with Spitalul Clinic Colentina in Bucharest, Romania. Stephen Stone, past president of the American Academy of Dermatology, confirms this is Lewandowsky-Lutz. In November 2007, a new video of a 34-year-old Indonesian man named Dede Koswara with a similar disease appeared on the Internet.[12] His story has appeared in the USAs Discovery Channel and TLC series My Shocking Story (Extraordinary People on UKs Five) in the episode Half Man Half Tree.[ And then on August 12, 2008, Dede Koswaras story was the subject of an ABCs 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 hands. 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, or Jobs Tears. The medicine is still undergoing a lab test.
