ABSTRACT
Resumen Introducción: La actinomicosis, es una infección crónica rara producida por bacterias del género Actinomyces sp. La afectación pélvica es una de sus formas más infrecuentes y en gran parte de los casos se relaciona al uso de un dispositivo intrauterino de larga data o a una cirugía previa. Como otras enfermedades raras, la infección es conocida como "la gran imitadora" por su variada forma de presentación y particular comportamiento pudiendo simular una neoplasia. El tratamiento es fundamentalmente médico y de buenos resultados. Caso Clínico: Damos a conocer el caso de una paciente que se presentó con un cuadro compatible con un tumor de recto, pero que resultó ser actinomicosis. El diagnóstico se realizó en base a la tinción de Gram, el cuadro clínico y el antecedente de un dispositivo intrauterino abandonado por más de 25 años. Fue corroborado posteriormente mediante anatomía patológica y tratada en forma exitosa con antibióticos por un periodo extendido. Conclusión: Si bien la actinomicosis es una patología infrecuente, debe ser considerada en el diagnóstico diferencial de los pacientes que se presentan con tumores de la pelvis. Un alto índice de sospecha y una actitud diagnóstica activa son fundamentales para un tratamiento oportuno, seguro y eficaz de esta enfermedad.
Introduction: Actinomycosis is a rare chronic infection caused by bacterias of the genus Actinomyces sp. Pelvic involvement is one of its most infrequent forms and in many cases it is related to the use of a longstanding intrauterine device or a previous surgery. Like other rare diseases, the infection is known as "the great imitator" because of its varied form of presentation and its particular behavior, which can simulate a neoplasm. The treatment is fundamentally medical with good results. Case Report: We present the case of a patient who presented with a rectal tumor but that turned out to be Actinomycosis. The diagnosis was made based on the Gram stain, the clinical presentation and the history of an intrauterine device left for more than 25 years. It was subsequently corroborated by pathological anatomy and successfully treated with antibiotics for an extended period. Conclusion: Although actinomycosis is an infrequent pathology, it should be considered in the differential diagnosis of patients who present with tumors of the pelvis. An active diagnostic attitude and a high index of suspicion are fundamental for the timely, safe and effective treatment of this disease.

Abstract Asymptomatic female genital tract colonization with Actinomyces spp is not uncommon, particularly among intrauterine device users. Pelvic actinomycosis is an extremely rare disease. The clinical picture can resemble an advanced ovarian malignancy. We report a case of pelvic actinomycosis mimicking ovarian malignancy diagnosed postoperatively. Preoperative diagnosis is possible if there is a high index of suspicion, obviating extensive surgery and preserving fertility, since long term antibiotic treatment can be completely effective. Pelvic actinomycosis should be included in the differential diagnosis of women presenting a pelvic mass, especially if there is intrauterine device use history.
Resumo A colonização assintomática do aparelho genital feminino por Actinomyces spp não é infrequente, sobretudo em utilizadoras de dispositivo intra-uterino. A actinomicose pélvica é uma doença extremamente rara. O quadro clínico pode assemelhar-se ao de uma neoplasia maligna do ovário avançada. Relatamos um caso de actinomicose pélvica, simulando uma neoplasia maligna do ovário, com diagnóstico pós-operatório. O diagnóstico pré-operatório é possível se houver um elevado grau de suspeição, permitindo evitar cirurgias extensas e preservar a fertilidade, uma vez que o tratamento antibiótico prolongado pode ser totalmente eficaz. A actinomicose pélvica deve ser incluída no diagnóstico diferencial da mulher que apresente uma massa pélvica, sobretudo se houver história de uso de dispositivo intra-uterino.

Resumen La actinomicosis diseminada es muy infrecuente, así como la afección del sistema nervioso central (SNC) asociada, con mortalidad de hasta 28%. Sus manifestaciones pueden ser similares a cuadros infecciosos de otras etiologías, por lo que el conocimiento de la entidad aumenta la sospecha clínica y permite brindar un tratamiento oportuno. Se presenta el caso clínico de un adulto con edema en una extremidad superior como manifestación de una tromboflebitis y una lesión abscedada axilar, en que se confirmó una infección por actinomicetos. Presentó una diseminación hematógena con compromiso de SNC, de evolución fatal.
Actinomycosis is very rare, as well as the central nervous system (CNS) condition associated with it, presenting a mortality up to 28%. Its manifestations could be similar to infectious conditions from other etiologies, thus, having a better understanding of the entity increases clinical suspicion and also it can provide a timely treatment. The clinical case of an adult with edema in an upper extremity is presented as a manifestation of thrombophlebitis and an abscessed axillary lesion, in which actinomycetes infection was confirmed. He presented a haematogenous spread with CNS involvement, with fatal ending.

Actinomycosis is a rare inflammatory disease caused by Actinomyces israelii. It can mimic many other diseases, such as malignant neoplasms or inflammatory bowel disease. We present a case in which actinomycosis simulated a colonic neoplasia. (AU)

Pulmonary actinomycosis is a rare bacteriological disease, caracterized by local suppuration and an extensive fibroinflammatory process, with a possible pseudotumoral outcome. To report a new observation of a pulmonary actinomycosis. A 52-year-old patient, smoker, admitted in our department for infectious pneumopathy complicated by purulent pleurisy. Clinical and radiological findings were not contributive.Fiberoptic had evocate the diagnosis of bronchopulmonary cancer. Evolution had been marqued by abondant hemoptysia indicating right low lobectomie. The diagnosis of actinomycosis was obtained by the pathology of the surgical resection. Diagnosis of pulmonary actinomycosis can be difficult because it can mimic the presentation of lung carcinoma.If the diagnosis is no late established, and if the patient is correctely treated medically, the prognosis still excellent

Pelvic actinomycosis is an uncommon condition, often associated with the use of intrauterine contraceptive device (IUCD). Pelvic actinomycosis is rare accounting for 3% of all human actinomycotic infections. Ovarian actinomycosis is even rarer. Here, we present a 24-year-old woman using an IUCD for 3 1 / 2 years with right-sided adnexal mass, which was diagnosed postoperatively as tubo-ovarian actinomycosis. Many times, an appropriate management is overlooked or delayed due to its non-specific and variable clinical and radiological features. Sometimes, it can even mimic an advanced pelvic malignancy. Therefore, the gynecologist should consider the possibility of this infection to spare the patient from morbidity of radical surgical procedure.

We describe a case of actinomycosis of the gallbladder mimicking carcinoma. Sonography showed a hypoechoic mass replacing gallbladder lumen and engulfing a stone; contrast-enhanced computed tomography showed a heterogeneously enhanced thickened gallbladder wall with subtle, disrupted luminal surface enhancement, which formed a mass. As a result of the clinical and radiologic presentation, our impression was of gallbladder carcinoma. Actinomycosis should be included in the differential diagnosis when sonography and computed tomography findings show a mass engulfing the stone in the gallbladder and extensive pericholecystic infiltration with extension to neighboring abdominal wall muscle.
