Occurrence of Blastomyces dermatitidis in Israel. First autochthonous Middle Eastern case.

A nodule from the infrapatellar region of the left knee of a patient in Israel was found by fluorescent antibody staining to contain the tissue form cells of Blastomyces dermatitidis. The diagnosis was confirmed by culture and other mycological studies when a second lesion appeared below the right knee. This represents the first autochthonous case of blastomycosis from Israel and the Middle East.
