Dirofilariasis of the breast in france.

Sections of a nongravid adult female Dirofilaria, probably D. repens, were found within a subcutaneous nodule excised from the breast of a 45-year-old Frenchwoman. This is the 29th case of D. repens in man in France and the first in which the parasite was located in the breast. The patient apparently acquired the infection while vacationing in the southeastern Mediterranean region of the country.
