[Pelvic actinomycosis simulating adnexal malignant tumor].

The purpose of this report is to describe the case of a 35-year-old patient admitted to the National Oncology Institute in Rabat, Morocco for pelvic pain and deteriorating general status ongoing for 8 months. Clinical and ultrasonographic examination showed a heterogenous mass measuring 7 cm in maximum width located inferior and lateral to the inferior aspect of the right side of the uterus. These findings were suggestive of a malignant tumor of the right ovary. Ovariectomy and omentectomy were performed. Histological examination of surgical specimens demonstrated right tubo-ovarian actinomycosis associated with peritonitis. Genital tract actinomycosis is an uncommon finding in women of childbearing age. It is due to colonization by a pyogenic bacteria (Actinomyces) usually secondary to a gastrointestinal infection, e.g. ileocecum, and sometimes in association with the presence of an intrauterine device or foreign body. Based on this case report, the authors discuss abdominopelvic actinomyocosis with emphasis on tumor-like findings that can lead to misdiagnosis by clinicians and radiologists.

[Diagnosis and therapy of liver actinomycosis].

A 47-year-old man who had undergone gastrectomy for duodenal ulcer required repeated hospitalization due to recurrent fistulas in the region of the laparotomy scar and increased cholestasis and cachexia. An intrahepatic and subphrenic abscess was diagnosed clinically and by liver scan and confirmed by laparotomy. The histologic findings revealed actinomycosis. Through early surgical drainage and administration of 20 million units penicillin G daily it proved possible to discharge the patient completely cured after 2 months. The pathogenesis of liver actinomycosis is discussed.

[A case of bronchopulmonary actinomycosis diagnosed by transbronchial biopsy of a bronchial polypoid tumor].

A 32-year-old man with history of dental caries had been coughing up blood-tinged sputum since Jan 2000. Chest radiography and computed tomography (CT) scans revealed a solitary nodule with a peripheral infiltrative shadow in the left S 6. Fiberoptic bronchoscopy was performed, but yielded no significant findings. In April 2000, because the nodule had increased in size, bronchoscopy was performed again, and revealed a white smooth-surfaced polypoid tumor in the left B 6 c. A transbronchial biopsy of the polypoid tumor was performed, and the histological findings show long Grocco-positive hyphae that are visible under sulfur granules. Bronchopulmonary actinomycosis was diagnosed. The solitary nodule with a peripheral infiltrative shadow in the left S 6 was eliminated by antibiotic therapy including ABPC/SBT. ABPC and LVFX. This case is important, because there are few reports concerning diagnosis of bronchopulmonary actinomycosis using transbronchial biopsy of a bronchial polypoid tumor.

Actinomycosis as a rare complication of orthognathic surgery.

Modern orthognathic surgery is said to be clean contaminated due to the intraoral means of access. Complications after orthognathic surgery, a common operation, occur about 10% of the time. Actinomycosis, a rare specific infection, plays a negligible role. Diagnostically, it should be differentiated from other infections that occur a long time after the operation. Three cases of actinomycosis that occurred after orthognathic surgery were observed, and therapeutic measurements are described case by case.

[Pelvic and abdominal actinomycosis. Case report and review of the literature].

Pelvic and abdominal actinomycosis is a chronic suppurating granulomatosis caused by a Gram positive gem, Actinomyces Israelii. Manifestations of this rare disease may mimic cancer, inflammatory bowel disease, or diverticulitis. These syndromes lead to surgical exeresis. The diagnosis is obtained from the pathology report. We report the case of a 56 years old woman with large bowel obstruction secondary to extensive pelvic and abdominal actinomycosis. A review of the literature shows that the abdominal-pelvic form has been increasing over the past 10 years secondary to the increased and prolonged use of the intrauterine device. Treatment of this condition consists of a combination of antibiotics and surgery to achieve complete recovery.

[Abdomino-pelvic actinomycosis: a case report].

The actinomycosis is a chronic suppurative granulomatosis disease. It is owed to a bacillus gram positive; actinomycès israelli. The cervical and thoracic localizations are most frequent. The digestive localization represents 20% of cases. It interest very rarely the pelvis and the genital tracts. We bring back the observation of a patient old of 30 years admitted for mass abdominal. To the exam, the patient had a sensibility of the left hypochondriac area and we found a mass of 6 cm of diameter. To the rectal touch, we found a mass in the bag of Douglas. The echography and the computed tomography revealed a collection under the spleen and a pelvic collection. A rectotomy is performed. The bacteriological study isolates actinomycès israelli. The collection under the spleen is drained under radiological control. Actinomycès israelli is also recovered in the pus brought back by the puncture. The patient is treated by Penicillin. The patient had a favourable evolution. No etiology is found at this patient. For this observation, the collection was accessible to a drainage permitting the diagnosis and the treatment of the actinomycosis while avoiding a mutilated surgery.

[Pulmonary actinomycosis mimicking of mucosa-associated lymphoid tissue lymphoma by frozen section examination: report of a case].

A 59-year-old man was admitted to our hospital for hemoptysis. Chest X-ray films showed a mass shadow in the left lower lobe. Any definitive diagnosis could not be made after examinations including sputum culture and bronchial cytology. Exploratory thoracotomy was performed since malignancy was not excluded. During the operation, mucosa-associated lymphoid tissue (MALT) lymphoma was suspected based on the pathological findings of the frozen section. The permanent section of the resected specimen contained colonies of actinomycetes in the bronchus, and the peripheral region demonstrated marked infiltration of lymphocytes and plasma cells through the interstitium of alveolar walls and peri-bronchovascular sheath, with many lymphoid follicles. This case revealed pulmonary actinomycosis coexisted with lymphocytic interstitial pneumonia (LIP). We concluded that lymphoproliferative disease should be considered another candidate for the differential diagnosis from pulmonary actinomycosis.

Intra-abdominal actinomycosis presenting as complex abdominopelvic mass.

A rare case of intra-abdominal actinomycosis in a 70-year-old lady presenting as abdominopelvic mass mimicking malignancy is presented. Intra-abdominal actinomycosis may present a serious diagnostic problem both pre- and peroperatively and can lead to extensive surgical intervention due to the anticipation of malignancy. The diagnosis is difficult specially in the absence of characteristic discharging sinus. The diagnosis of this disease, potentially curable by antibiotic is more often made postoperatively by histopathology and microbiological methods.

[Vertebral actinomycosis: case report and review of the literature].

In this article, the case of a 32-year-old man with a paravertebral actinomycosis is discussed. Initially, the diagnosis was not obvious but it was confirmed later with the repetitive radiologic procedures, the elimination of other etiologies (purulent, mycobacterial or mycotic infections and neoplasia) and the biopsy. Treatment with penicillin initially and then with tetracycline for a long term led to a very good outcome at a 3-year follow-up with a radiologic remission. Following the discussion of the case, a review of the literature concerning the paravertebral actinomycosis, its diagnostic clues and treatment is undertaken.

[A case of pulmonary actinomycosis with recurrent hemoptysis].

A 68-year-old man was admitted to our hospital because of hemoptysis in September 1999. Chest CT scans showed a nodular shadow with infiltration in the right S 7. Bronchial arteriography showed vascularization in the right S 7, and bronchial artery embolization was performed. However, in April and October 2000 hemoptysis recurred, and bronchial arteriography showed recurrence of vascularization in the same area, so embolization was performed again. Then, the patient was admitted in March 2001 because of recurrent hemoptysis. CT scans showed growth of the nodular shadow. Right lower lobectomy was performed, and the microscopic findings in the tissue from the resected lobe showed branching filamentous bacteria, and pulmonary actinomycosis was diagnosed. We concluded that pulmonary actinomycosis should be considered in the differential diagnosis of nodular shadows with recurrent hemoptysis.

[A case of pulmonary actinomycosis with a unique finding in the chest MR image].

A 57-year old man, who was complaining of a productive cough and right shoulder pain, was admitted to our hospital because of an irregularly shaped mass located at rt. S1 on a chest radiograph. Bronchoscopy revealed no evidence suggesting lung cancer or any specific infection, either pathologically or microbiologically. CT-guided biopsy revealed changes resembling lymphocytic or plasmocytic interstitial pneumonitis with thickening of the alveolar septum and with accumulations of mononuclear cells and plasma cells, indicating the proliferation of bronchus-associated lymphoid tissue (BALT system). Since no definitive diagnosis was considered possible, a right upper lobectomy was performed. Histopathologic examination of tissue from the right upper lobe revealed sulfur granules and branching Gram-positive filamentous bacteria, and the condition was pathologically diagnosed as pulmonary actinomycosis. In the center of the mass lesion, the patient's chest MRI showed a very small area with a low signal intensity in T1- and a high signal in T2-weighted images, which suggested an accumulation of fluid in the actinomycotic abscess. As detailed MR findings in this condition have not been well described in the literature, the MRI evidence seen in this case may be useful for the diagnosis of actinomycosis.

[Pseudotumoral thoracic actinomycosis with lung and brain metastases. Apropos of a case. Review of hundred thirty one cases in the literature].

One particular case of thoracic actinomycosis is reported. The patient presented with a neurological picture mimicking a metastasis, as chest radiogram and CT-Scan indicated a primary pulmonary tumor. Diagnosis of actinomycosis was overlooked and final diagnosis was based on direct microscopy of lung tumor, which required a thoracotomy, without any resection. Antibiotic treatment with penicillin was successful as the cerebral lesion was completely cured within 2 months and the thoracic lesion reduced 2/3rd volume within the same delay. The importance of correct handling of tissue specimens and adequate informations to the microbiologist are emphasized. Another point of interest is that good clinical results can be expected from prolonged antibiotic treatment. Surgery must be reserved for diagnosis if no other means has been effective, for failure of medical treatment or for acute complications.

CT findings of pediatric thoracic actinomycosis: report of four cases.

Thoracic actinomycosis is an uncommon disease, which may mimic malignancy, lymphoma or tuberculosis of the chest. In the past three years, four cases of thoracic actinomycosis have been found in children at our hospital. Their computed tomography (CT) findings included pulmonary infiltrates, a chest wall mass, pleural and pericardial effusion, mediastinum involvement and rib changes. Although the final diagnosis of Actinomyces infection depends on a bacterial culture and pathology, CT can play an important role in establishing the diagnosis and evaluating the extent of the disease.

[Abdominal actinomycosis. Actinomycotic abscess 10 years after appendectomy].

A case of actinomycosis of the abdomen ten years after surgery for acute appendicitis is reported. The patient, a 2 1/2 years old girl at the time of operation, presented with acute abdominal pain ten years after appendectomy. Computed tomography (CT) showed a mass in the region of the right psoas muscle. Fine needle aspiration revealed pus which on culture was found to contain Actinomyces israeli. Since surgery is a well known probable cause of abdominal actinomycosis, we must assume the appendectomy and the formation of the actinomycotic abscess to be related. Discovery of an abdominal mass even years after violation of the gastrointestinal tract should arouse suspicion of an abscess involving these otherwise infrequent pathogens.

[Cervicofacial actinomycosis. A case study].

A case of cervicofacial actinomycosis, sited in the central hyoid region, is reported. The Authors have emphasized the difficulties of the diagnosis. It's very important hat the clinical diagnosis of actinomycotic infection be confirmed by a positive culture test. Actinomycosis can be suspected if multiple recurrent pustular swellings are present, associated with any trauma or teeth extractions.

[Digestive hemorrhage secondary to ileocecal actinomycosis].

Report of a case of abdominal actinomycosis, including the cecoapendicular region, that clinically presented as lower digestive bleeding, and was diagnosed by the anatomopathological study of the surgical resection specimen, since the patient was operated with the preoperative diagnosis of vascular malformation. This type of presentation is uncommon in abdominal actinomycosis, and explains the presentation of this clinical case.
