Unusually extensive disease caused by Leishmania major parasites.

Simple cutaneous leishmaniasis (CL), which is endemic in several areas of Israel, is usually caused by Leishmania major. CL, which is caused by replication of parasites within dermal macrophages, is self-limited and almost always confined to the skin. We recently encountered two cases of CL in which skin defenses were breached and lesions appeared in subcutaneous locations. In one case, abnormal cell-mediated immune function was detected. The purpose of this article is to present these data and to comment on the immunological aspects of leishmaniasis.

Full skin thickness burns caused by contact with the pavement in a heat-stroke victim.

A 70-year-old woman, with a previous history of heat-stroke, suffered another heat-stroke on a hot summer day (air temperature 43 degrees C (109 degrees F)). She presented the rare complication of a heat-stroke plus deep burns sustained while lying unconscious on the pavement. In addition to age, obesity, previous illness, incidental fever, drugs, dehydration and physical effort, a previous history of heat-stroke is probably an important risk factor for a second heat-stroke. Burns from contact with the pavement are uncommon but possible, especially if the patient is obese, immobile and poorly insulated.

Specific cutaneous infiltrates in chronic myelogenous leukemia.

Specific leukemic infiltration of the skin is possible in all types of leukemia, and occurs most commonly in monocytic leukemias. We report the case of a 76-year-old woman with chronic myelogenous leukemia who showed specific cutaneous lesions one month before she died. In the absence of other signs of accelerated disease or blast crisis, cutaneous lesions should be considered an ominous sign in chronic myelogenous leukemia.
