“…Attar et al [7] reported cases of breast infection caused by A. turicensis and A. radingae. All cases of breast actinomycosis involved premenopausal women, except for 1 case described by de Barros et al [3]. Our patient was also in the early postmenopausal period.…”

Primary Actinomycosis of the Breast Presenting as a Breast Mass

Background: Primary actinomycosis of the breast is a rare disease which may present as sinus tract or with mass-like features mimicking malignancy. Clinical presentation makes it difficult to distinguish primary actinomycosis from mastitis and inflammatory carcinoma. Case Report: A 48-year-old woman presented with a mass in the left breast of 2 months duration. Physical examination was significant for a non-tender mass in the left breast. Histopathologic examination of the excisional biopsy of the mass showed granulomatous inflammation with grains of Actinomyces israelii. Conclusions: Actinomycosis of the breast usually presents as a recurrent abscess with fistulas. It may sometimes present as a breast lump, which is difficult to distinguish from inflammatory carcinoma. The diagnosis is made by histopathologic examination of the specimen, in which we can see the characteristic sulfur granules representing the bacterial colonies. Prolonged antibiotic therapy with penicillin is the treatment of choice.

“…Disruption of the mucosal barrier is the usual precursor to infection with Actinomyces species and, in the breast, the ductal system may serve as a portal of entry. Actinomycosis of the breast usually presents as a chronic, recurrent abscess which in some cases can be difficult to distinguish from inflammatory carcinoma (9,15,26). Fistulas and purulent or bloody discharge from sinuses may occur, which may discharge sulfur granules (26).…”

Actinomycosis is a chronic infection caused by Actinomyces species characterized by abscess formation, tissue fibrosis, and draining sinuses. The spectrum of infections caused by Actinomyces species ranges from classical invasive actinomycosis to a less invasive form of superficial skin and soft tissue infection. We present a review detailing all Actinomyces species isolated from breast infections in NHS Lothian between 2005 and 2013, Actinomyces species isolated from breast infections referred to the United Kingdom Anaerobe Reference Unit between 1988 and 2014, and cases describing Actinomyces breast infections published in the medical literature since 1994. Actinomyces species are fastidious organisms which can be difficult to identify and are likely to be underascertained as a cause of breast infections. Due to improved diagnostic methods, they are increasingly associated with chronic, recurrent breast infections and may play a more significant role in these infections than has previously been appreciated.
