“…More cases with a good clinical and radiological description are needed to improve the preoperative diagnosis of abdominal actinomycosis. As to our knowledge, this is the first case of appendiceal actinomycosis reported in México [21] , [22] , [23] , [24] , [25] .…”

“…Both Actinomyces and Nocardia infections are rarely associated with body cavity effusions (ie, thoracic, pericardial, peritoneal) . Typically, these effusions present secondary to associated mass lesions or pseudotumors.…”

“…Typically, these effusions present secondary to associated mass lesions or pseudotumors. Rare reports of spontaneous peritonitis due to Actinomyces without preceding abscess formation or inciting event have been described, and in the single report with cytologic preparations, sulfur granules were microscopically identified . On macroscopic examination, these effusions range from serosanguinous to densely purulent, and cytology may not always detect the bacteria .…”

Nocardia species and Actinomyces species are 2 of the most commonly diagnosed filamentous bacteria in routine cytopathology practice. These genera share many overlapping cytomorphologic features, including their thin, beaded, branching, Gram-positive, GMS-positive filamentous structures that fragment at their peripheries into bacillary- and coccoid-appearing forms. Features that help distinguish between these 2 microorganisms include the width of their filamentous structures, the angles at which they branch, and their ability or lack thereof to retain a modified acid-fast stain. In addition to cytomorphologic overlap, overlap in clinical presentation is frequent with pulmonary and mucocutaneous presentations seen in both. Differentiating between Nocardia and Actinomyces is essential because patients with these infections require different approaches to medical management. Both antibiotic susceptibilities and the need for early surgical intervention as part of the treatment plan vary greatly among these 2 groups. This review focuses on the clinical presentation, cytomorphology and staining characteristics that can be useful in identifying and distinguishing between Nocardia and Actinomyces infections, as well as their mimickers.

“…Cultivated growth of Actinomyces can be expected after a period of 5 to 21 days [ 1 – 3 ] and in more than 50% of assumed actinomycosis cases there is no growth of the species found at all [ 2 ]. Actinomyces bacteria are part of the commensal flora in the oropharynx, gastrointestinal tract, and female urogenital tract [ 1 – 5 ]. An endogenous infection can arise after erosion of the mucosa followed by invasion and pathogenicity of these bacteria [ 1 – 3 ].…”

Patient: Female, 42Final Diagnosis: Spontaneous pelvic-abdominal peritonitis due to actinomycesSymptoms: Abdominal distension • abdominal pain • acute abdomen • fever • intermenstrual bleeding • nausea • sepsis • septic shockMedication: —Clinical Procedure: —Specialty: SurgeryObjective:Unusual clinical courseBackground:Pelvic-abdominal actinomycosis is a rare chronic condition caused by an anaerobic, gram-negative rod-shaped commensal bacterium of the Actinomyces species. When Actinomyces becomes pathogenic, it frequently causes a chronic infection with granulomatous abscess formation with pus. Due to diversity in clinical and radiological presentation, actinomycosis can easily be mistaken for several other conditions. Peritonitis without preceding abscess formation caused by Actinomyces species has been described in only few cases before in literature.Case report:We report a case of spontaneous pelvic-abdominal peritonitis with presence of pneumoperitoneum and absence of preceding abscesses due to acute actinomycosis mimicking a perforation of the proximal jejunum in a 42-year-old female with an intra-uterine contraceptive device in place. Explorative laparotomy revealed 2 liters of odorless pus but no etiological explanation for the peritonitis. The intra-uterine contraceptive device was removed. Cultivation showed growth of Actinomyces turicensis. The patient was successfully treated with penicillin.Conclusions:In the case of primary bacterial peritonitis or lower abdominal pain without focus in a patient with an intrauterine device in situ, Actinomyces should be considered as a pathogen.
