“…It is important to differentiate this case, wherein an immunocompetent patient had a previous subclinical Leishmania infection, from the previously referenced cases in which the parasite was inoculated by agents other than phlebotomine sand flies 2,3 . It is believed that disease activation was triggered by the electrocoagulation procedure, characterized as the known locus minoris resistentiae phenomenon 12 .…”

“…Usually, CL is transmitted by infected phlebotomine sand fly bites, and a subclinical infection in the host has been proven 1 . There are a few reports that describe unusual modes of parasite infection, such as through direct contact, rat bites, accidental laboratory inoculation 2,3 , localized trauma 4,5 , and the use of immunomodulators such as anti-tumor necrosis factor (TNF)-alpha 6,7 . Here, we report a case of American tegumentary leishmaniasis (ATL) following electrocoagulation for a seborrheic keratosis skin lesion.…”

Cutaneous leishmaniasis is usually transmitted by infected phlebotomine sand fly bites that initiate local cutaneous lesions. Few reports in the literature describe other modes of transmission. We report a case of a previously healthy 59-year-old woman who underwent electrocoagulation to remove seborrheic keratosis confirmed by dermatoscopy. Three months later, a skin fragment tested positive for Leishmania culture; the parasite was identified as L. (V.) braziliensis. Trauma may generate inflammatory cascades that favor Leishmania growth and lesion formation in previously infected patients. American cutaneous leishmaniasis is a dynamic disease with unclear pathophysiology because of continually changing environments, demographics, and human behaviors.

Laboratory-Acquired Parasitic Infections from Accidental Exposures

SUMMARY Parasitic diseases are receiving increasing attention in developed countries in part because of their importance in travelers, immigrants, and immunocompromised persons. The main purpose of this review is to educate laboratorians, the primary readership, and health care workers, the secondary readership, about the potential hazards of handling specimens that contain viable parasites and about the diseases that can result. This is accomplished partly through discussion of the occupationally acquired cases of parasitic infections that have been reported, focusing for each case on the type of accident that resulted in infection, the length of the incubation period, the clinical manifestations that developed, and the means by which infection was detected. The article focuses on the cases of infection with the protozoa that cause leishmaniasis, malaria, toxoplasmosis, Chagas' disease (American trypanosomiasis), and African trypanosomiasis. Data about 164 such cases are discussed, as are data about cases caused by intestinal protozoa and by helminths. Of the 105 case-patients infected with blood and tissue protozoa who either recalled an accident or for whom the likely route of transmission could be presumed, 47 (44.8%) had percutaneous exposure via a contaminated needle or other sharp object. Some accidents were directly linked to poor laboratory practices (e.g., recapping a needle or working barehanded). To decrease the likelihood of accidental exposures, persons who could be exposed to pathogenic parasites must be thoroughly instructed in safety precautions before they begin to work and through ongoing training programs. Protocols should be provided for handling specimens that could contain viable organisms, using protective clothing and equipment, dealing with spills of infectious organisms, and responding to accidents. Special care should be exercised when using needles and other sharp objects.
