Abstract
Purpose of Review Travel medicine practitioners often are confronted with returning travelers with dermatologic disorders that could be of infectious causes or inflammatory or allergic. Some dermatologic processes are the result of exposure to insects or acquired due to environmental exposures. There is a broad range of dermatosis of infectious and non-infectious etiologies that clinicians need to consider in the differential diagnosis of dermatosis in travelers. Recent Findings With increasing international travel to tropical destinations, many individuals may be exposed to rickettsia (i.e., African tick bite fever, scrub typhus, or Mediterranean spotted fever), parasitic infections (i.e., cutaneous larva migrans, cutaneous leishmaniasis, African trypanosomiasis, or American trypanosomiasis), viral infections (i.e., measles or Zika virus infection), bacterial (i.e., Buruli ulcer) or ectoparasites (scabies or tungiasis), and myiasis. Cutaneous lesions provide clinical clues to the diagnosis of specific exposures during travel among returned travelers. Summary Dermatologic disorders represent the third most common health problem in returned travelers, after gastrointestinal and respiratory illness. Many of these conditions may pose a risk of severe complications if there is any delay in diagnosis. Therefore, clinicians caring for travelers need to become familiar with the most frequent infectious and non-infectious skin disorders in travelers.

Abstract
Purpose of Review International and domestic travelers may acquire a wide variety of infectious diseases transmitted by exposure to insects. Exposure to ticks may be associated with systemic infections clinically suspected through skin and soft tissue manifestations along with fever, myalgia, headache, and other related symptoms. Cutaneous lesions may include eschars at the site of initial contact, maculopapular rashes, or others as the result of systemic dissemination of viral, Rickettsial, parasitic, and protozoan infections acquired by exposure to different types of ticks. Recent findings Ticks represent the second most common global vector of transmission of infectious diseases to humans after mosquitoes. In some endemic regions, ticks are the most important vector of transmission of a great variety of infectious pathogens including protozoan (Babesia spp.), viral (Coltivirus), rickettsia, and bacterial infections (Francisella tularensis). With increasing international travel, different tick-borne diseases continue to emerge and being identified. Summary Identifying the cutaneous signs associated with tick-borne diseases is crucial to clinically suspect the diagnosis of a specific tick-borne illness. Minimizing the exposure to ticks during domestic or international travel represents the most important intervention to reducing the risk of tick-borne illnesses.

Abstract
BACKGROUND Morphea clinically presenting as cordoniform lesions has not been described previously in the literature. OBJECTIVE Our goal was to describe the clinicopathologic features of morphea presenting with cord-like cutaneous lesions. METHODS The clinical notes of 420 patients with a diagnosis of morphea seen during the previous 10 years were reviewed to identify any cases that had cordoniform lesions at presentation. RESULTS Two adult patients (one male and one female) were identified. Both patients presented with chronic, slightly burning, bilateral, erythematous, linear or curvilinear elevated cutaneous indurations on the lateral chest wall strikingly reminiscent interstitial granulomatous dermatitis with arthritis. Histopathologically, typical changes of deep morphea with a band-like involvement only of the lower part of the reticular dermis and the superficial hypodermis and a remarkable perineural arrangement of the lymphoplasmocytic infiltrate were observed. The presence of Borrelia in skin biopsy samples of both patients was shown by immunohistochemistry and focus floating microscopy. In one patient, the presence of Borrelia afzelii DNA in the cutaneous biopsy was shown by polymerase chain reaction. CONCLUSIONS Cordoniform morphea is an exceedingly unusual and previously undescribed clinicopathologic presentation of morphea where Borrelia infection may play a causal role.

Abstract
OBJECTIVE To evaluate the causes and risks for imported skin disorders among travellers. METHODS Data of 34,162 travellers returning from tropical and non-tropical countries and presenting at the outpatient travel medicine clinic of the University of Munich, Germany, between 1999 and 2009 were analyzed for this study. Of these, 12.2% were diagnosed with skin disorders. RESULTS Main destinations visited were Asia (40%), Africa (27%) and Latin America (21%). Tourism in the form of adventure travel/backpacking (47%) and package holidays (23%) was the most common purpose of travel. The leading causes of skin disorders were arthropodal (23%), bacterial (22%), helminthic (11%), protozoan (6%), viral (6%), allergic (5%) and fungal (4%). The 10 most frequently diagnosed specific skin diseases associated with specific destinations were insect bites (17%, Southern Europe), cutaneous larva migrans (8%, Asia and Latin America), cutaneous leishmaniasis (2.4%, Mediterranean Region/Middle East), dengue fever (1.5%, Asia), rickettsioses (1.3%, Southern Africa), myiasis (0.8%, Central America), filarioses (0.7%, Africa), tick bites (0.6%, Central/Eastern Europe), schistosomiasis (0.6%, Africa) and tungiasis (0.6%, Africa). Travellers in sub-Saharan Africa had the highest relative risk of acquiring skin disorders. CONCLUSION As more than 20% of all skin disorders among returned travellers were caused by arthropods and about 50% by infectious pathogens, pre-travel consultations should include specific prophylaxis and consider the most important risk factor for the travel destination.

Abstract
Hookworm-related cutaneous larva migrans is caused by the migration of animal hookworm larvae in the human skin. The disease mainly occurs in resource-poor communities in the developing world, but it is also reported sporadically in high-income countries and in tourists who have visited the tropics. Diagnosis is made clinically in the presence of a linear serpiginous track moving forward in the skin, associated with itching and a history of exposure. Itching is typically very intense and can prevent patients from sleeping. Bacterial superinfection occurs as a result of scratching. Treatment is based on oral drugs (albendazole or ivermectin) or the topical application of tiabendazole. To control hookworm-related cutaneous larva migrans at the community level, regular treatment of dogs and cats with anthelmintic drugs is necessary, but this is seldom feasible in resource-poor settings. Animals should be banned from beaches and playgrounds. For protection at the individual level, unprotected skin should not come into contact with possibly contaminated soil.

Abstract
Skin ulcers are a commonly encountered problem at departments of tropical dermatology in the Western world. Furthermore, the general dermatologist is likely to be consulted more often for imported chronic skin ulcers because of the ever-increasing travel to and from tropical countries. The most common cause of chronic ulceration throughout the world is probably pyoderma. However, in some parts of the world, cutaneous leishmaniasis is one of the most prevalent causes. Mycobacterium ulcerans is an important cause of chronic ulcers in West Africa. Bacterial infections include pyoderma, mycobacterial infections, diphtheria, and anthrax. Pyoderma is caused by Staphylococcus aureus and/or beta-hemolytic streptococci group A. This condition is a common cause of ulcerative skin lesions in tropical countries and is often encountered as a secondary infection in travelers. The diagnosis is often made on clinical grounds. Antibacterial treatment for pyoderma should preferably be based on culture outcome. Floxacillin is generally active against S. aureus and beta-hemolytic streptococci. Infection with Mycobacterium ulcerans, M. marinum, and M. tuberculosis may cause ulcers. Buruli ulcers, which are caused by M. ulcerans, are endemic in foci in West Africa and have been reported as an imported disease in the Western world. Treatment is generally surgical, although a combination of rifampin (rifampicin) and streptomycin may be effective in the early stage. M. marinum causes occasional ulcerating lesions in humans. Treatment regimens consist of combinations containing clarithromycin, rifampin, or ethambutol. Cutaneous tuberculosis is rare in travelers but may be encountered in immigrants from developing countries. Treatment is with multiple drug regimens consisting of isoniazid, ethambutol, pyrazinamide, and rifampin. Cutaneous diphtheria is still endemic in many tropical countries. Cutaneous diphtheria ulcers are nonspecific and erythromycin and penicillin are both effective antibacterials. Antitoxin should be administered intramuscularly in suspected cases. Anthrax is caused by spore-forming Bacillus anthracis. This infection is still endemic in many tropical countries. Eschar formation, which sloughs and leaves behind a shallow ulcer at the site of inoculation, characterizes cutaneous anthrax. Penicillin and doxycycline are effective antibacterials. Cutaneous leishmaniasis is caused by different species belonging to the genus Leishmania. The disorder is one of the ten most frequent causes of skin diseases in travelers returning from (sub)tropical countries. The clinical picture is diverse, ranging from a painless papule or nodule to an ulcer with or without a scab. Treatment depends on the clinical manifestations and the species involved.Sporotrichosis, chromo(blasto)mycosis, and mycetoma are the most common mycoses that may be accompanied by ulceration. Infections are restricted to certain regions and often result from direct penetration of the fungus into the skin. Anti-mycotic treatment depends on the microorganism involved. The most common causes of infectious skin ulceration encountered in patients from tropical countries who present at a department of tropical dermatology are reviewed in this article.

Abstract
BACKGROUND Hookworm-related cutaneous larva migrans (CLM) and tungiasis are commonly diagnosed in travelers returning from endemic areas, but reliable data on disease occurrence do not exist. To describe the occurrence of CLM and tungiasis in international travelers, a cross-sectional study was done. METHOD We conducted an airport survey in European travelers exiting northeast Brazil. Questionnaires were distributed at the departure gate of the international airport of Fortaleza (Ceará State) while passengers were waiting to board their plane. The questionnaire included questions on personal characteristics, pretravel health advice, acquired parasitic skin diseases during their stay in Brazil, and clinical characteristics of the infestation. To help identify CLM and tungiasis, photographs of the typical appearances of the infestations were presented. RESULTS Data from 372 tourists (aged 16-76 y, median = 40 y) were available for analysis; 45% had obtained pretravel health advice, usually from travel clinics (46.2%) and Internet sites (39.6%). Only 14% of those who obtained advice had been informed about CLM as a travel health risk and 22% about tungiasis. During their stay in Brazil, 12 (3.2%) tourists had experienced tungiasis and 3 (0.8%) CLM. In all cases, lesions were confined to the feet. The three travelers with CLM complained of irritability; itching was present in two cases. Pain (58.3%) and itching (50%) were the most common symptoms in travelers with tungiasis. The length of stay was a clear predictor for tungiasis, with a 20 times higher occurrence in travelers who had stayed for more than 4 weeks in Brazil. CONCLUSIONS Tungiasis and CLM are not rare in international tourists departing from Brazil, and pretravel counseling is insufficient. Pretravel health advice should include information on the risk of acquiring tungiasis and CLM and how to prevent an infestation. Airport surveys using questionnaires can be used to obtain incidence data on both parasitic infestations.

Abstract
Tungiasis and myiasis are common ectoparasitic infestations that occur in developing countries in the tropics, particularly where poverty and poor standards of basic hygiene exist. The growth in international travel to and from these regions has led to an increase in the presentation of these conditions in nonendemic countries. Despite recent progress in the treatment and prevention of tungiasis and myiasis, diagnosis can present a challenge to those unfamiliar with these conditions, especially when they present in nonendemic countries. Tungiasis is caused by the penetration of the female sand flea, Tunga penetrans, into the epidermis of the host. Myiasis is a parasitic infection of the skin and mucous membranes in which the larvae of Diptera insects penetrate healthy or altered skin depending on the species. Infestations are usually self-limited and present few complications. Social neglect and inadequate health behavior in economically depressed urban neighborhoods, however, may lead to secondary infections and complications.
