Background:
We present a case of Actinomyces israelii causing vulvar mass suspicious for malignancy in a postmenopausal woman.
Case:
A 60 year-old woman presented due to a firm, nonmobile, 10 cm vulvar mass, which had been rapidly enlarging for 5 months. The mass was painful, with localized pruritus and sinus tracts oozing of serosanguinous fluid. Biopsy and cultures revealed a ruptured epidermal inclusion cyst containing granulation tissue and Actinomyces israelii.
Conclusion:
Actinomyces israelii may produce vulvar lesions that are suspicious for malignancy. Thus, biopsies and cultures are both mandatory while evaluating vulvar masses suspicious for malignancy.
