“…This branching and generally low, virulent, Gram-positive organism is a normal commensal of the gastrointestinal tract and causes recurrent abscesses or nonhealing ulcers and may mimic a neoplastic lesion. Previous reports have described actinomycosis in other locations in the genital tract of males [24,25,26]. The infection is rarely related to systemic disease in immunocompromised hosts.…”

Pilonidal sinus is a well-recognized condition that occurs most commonly in the sacrococcygeal area of younger men. It is hypothesized to be an acquired chronic inflammation condition due mainly to hair trapped beneath the surface. A pilonidal sinus in the sacrococcygeal region is associated with recurrent infection, abscess formation, cellulitis, fistulae, and rarely, squamous cell carcinoma. A pilonidal sinus of the penis is a rare entity. The association of a penile pilonidal cyst and Actinomyces is even more uncommon with only three cases reported previously. Two cases of pilonidal sinus are reported in this paper. One of the cases was associated with actinomycosis. Pilonidal sinus of the penis should be considered in the clinical and pathological differential diagnosis and has to be distinguished from balanoposthitis, epidermal cyst, and carcinoma. The knowledge about possible association with actinomycosis is important to ensure early treatment.

Primary Vesical Actinomycosis: A Case Diagnosed by Multiple Transabdominal Needle Biopsies

Primary vesical actinomycosis is an extremely rare disease. In most cases it is misdiagnosed as vesical or urachal tumor and usually diagnosed through post-operative pathologic confirmation. Here we report a case of primary vesical actinomycosis confirmed by preoperative repeated multiple transabdominal biopsies. The patient was a 49-yr-old woman who presented with frequency, dysuria, and intermittent gross hematuria for 2 months. Computed tomography and cystoscopic examination showed broad-based, edematous, and protruding mass at the dome and anterior portion of the bladder. The clinical and imaging findings of the patient initially suggested vesical malignancy. Transurethral resection and multiple biopsies of the mass were performed. Pathologic examination demonstrated fibrosis with chronic inflammation. We performed repeated transabdominal multiple needle biopsies for further pathologic confirmation. Histopathologic examination demonstrated typical sulfur granules, which were consistent with actinomycosis.

“…On brief review of the literature, it appears that five previous cases of Actinomyces prostatic soft tissue infection have been described (Liedana et al, 1979;de Souza et al, 1985;Funke and von Graevenitz, 1995;Chemsi et al, 2007). A. neuii does not cause classical actinomycosis but is the causative agent of (soft) tissue infections, e.g.…”

Repetitive urinary tract infections and two prostatic masses: Prostatic soft tissue infection with Actinomyces neuii

Actinomyces infection is a tissue destructive, low-grade infection that often resembles malignancy. We report the case of a 70-year-old male with repeated, culture-negative urinary tract infections while intermittently catheterized. At presentation, the patient reported a new episode of urinary tract infection with white discharge in his urine. Transrectal ultrasonography showed two lesions in the prostate, suspect for prostate cancer. However, biopsy did not show cancer, and anaerobic culture grew Actinomyces neuii. A 3-month antibiotic course of amoxicillin eventually cured the infection. This is a case of prostatic soft tissue infection with A. neuii. It is important to consider Actinomyces infection in patients with a non-malignant prostatic mass. Although β-lactam antibiotics do not penetrate the prostate well, the Actinomyces infection was cured by prolonged amoxicillin treatment in this case. It is possible that the tissue damage enhanced the amoxicillin concentration in the infected prostate.

Actinomycosis of the Prostate

Abstract: We report a case of actinomycosis of the prostate with symptoms of acute prostatitis. Laparotomy was required to establish an etiological diagnosis. Long-term therapy with erythromycin resulted in a clinical cure.
