Actinomycosis - Ovary
Image Description
Pelvic actinomycosis is usually associated with prolonged use (> 3 yrs.) of an Intrauterine Device (IUD). Ovarian involvement manifests as a unilateral tubo-ovarian mass consisting of multiple abscesses filled with blood-tinged exudate. The image shows an actinomycotic (sulfur) granule enveloped by an infiltrate composed of neutrophils, foamy histiocytes, lymphocytes and plasma cells.
