Arch Dermatol. 1977;113(8):1122. doi:10.1001/archderm.1977.01640080124025

With the ease and frequency of worldwide travel, unfamiliar diseases are often encountered by the American physician. We would like to share two such cases that are infrequently reported in the United States.1-3

Report of Cases  Two middle-aged women traveled to Costa Rica in June 1976 on a three-week bird-watching expedition. During this time, they remained in good health, except for sustaining some insect bites. In early July, a few days after their return to the United States, one woman noted intense pruritus associated with small papules on the upper part of her back, and the other noted it on the proximal portion of her upper extremities. The papules gradually enlarged and formed nodules with small apertures. Both women were seen after two weeks of symptoms. One of the patients had extracted a "worm" from one of the lesions on her arm, which she brought with her (Fig 1).
