Abdominal actinomycosis is a chronic granulomatous suppurative disease caused by anaerobic Gram positive germs from Actinomyces species. The vermiform appendix and ileocaecal region have been recognized as the most commonly involved sites. Actinomycosis of the appendix is generally acute in presentation, mimicking a common acute appendicitis. We present a case of actinomycosis of the appendix in a 62-year-old male patient. The clinical presentation was as for a common acute appendicitis. The ultrasound examination sustained the diagnosis of acute appendicitis and an appendectomy was performed. The diagnosis was established by histo-pathologic examination. The cultures from intraperitoneal fluid were negative. The association of a long-standing antibiotic therapy to the surgical treatment resulted in definitive cure for this patient. Actinomycosis of the appendix is a rare disease that must be known, the diagnostic being the key for a successful treatment.

We present three cases of abdominal actinomycosis in females, one presenting with an abdominal mass and the two others underwent emergency surgery because of acute abdomen with a diagnosis of complicated acute appendicitis. The first patient (age 36 years) presented with an abdominal mass in the left lower quadrant arising from the colon as observed by abdominal computed tomography (CT). The patient was brought to the operating room and tumoral resection was done. The second and third patients (37 years and 39 years, respectively) were brought to the emergency room because of acute abdominal pain with leucocytosis. Exploratory laparotomy was performed, finding in the second patient a bilateral ovarian abscess and uterine perforation. Hysterectomy and salpingo-oophorectomy were done. In the third patient, the findings were a sigmoid mass and a bilateral tubo-ovarian abscess and these organs were resected. Samples were sent for pathologic analysis. Microscopic analysis of the specimens sent revealed the presence of "sulfur granules," and a diagnosis of actinomycosis was made. Abdominal actinomycosis is a rare disease and preoperative diagnosis is uncommon. It is necessary to complete the full course of antibiotic therapy in order to completely eradicate the disease.

Actinomycosis is an uncommon chronic infectious disease. Common sites of involvement include the cervicofacial, thoracic and abdominopelvic regions. In abdominopelvic actinomycosis, the ileocecal region, including the appendix, is the most commonly involved site. In some reports, limited appendiceal actinomycosis has revealed a thickened appendiceal wall with peri-appendiceal inflammation as acute appendicitis or perforated appendicitis. We experienced pathologically confirmed intraluminal limited appendiceal actinomycosis without peri-appendiceal infiltration. Here, we report the computed tomography and ultrasound findings.

Abdominal actinomycosis in children is a rare disease, which is occasionally found on histologic examination after an operation for acute appendicitis. Because of its nonspecific clinical and radiological signs and symptoms and low prevalence, the diagnosis is hardly ever made before the patient undergoes an operation and tissue is available for pathologic evaluation. When the diagnosis is made, the patient should be treated with the appropriate long-term antibiotics. With antibiotic therapy, the prognosis is favorable. We describe a 13-year-old girl who presented with acute appendicitis and was found to have abdominal actinomycosis after undergoing open appendectomy, which was treated successfully with penicillin and piperacillin-tazobactam.

Since actinomycosis sometimes causes an abdominal tumor which mimics malignancy, treatment strategy varies from case to case. We herein report two cases which were treated with a combination of antibiotics and surgical intervention. Both patients presented with an intra-abdominal tumor lesion mimicking malignant disease after an appendectomy for acute appendicitis. Case 1 received surgical extirpation of the abdominal tumor in the liver and kidney twice since the clinical diagnosis of actinomycosis was not made. In contrast, case 2 was successfully treated by a combination of antibiotics and laparoscopic surgery following the experience of case 1. When a high probability diagnosis can be made, a laparoscopic approach is a useful and effective option to treat this condition.

Acute appendicitis is the most frequent emergency in gastrointestinal surgery. Obstruction of the appendiceal lumen appears to be one of the most common physiologic mechanisms for the development of acute appendicitis. Once obstructed, the dilatation of the lumen causes ischemia and necrosis of the wall. The most common organisms involved in appendicitis are Escherichia coli, Peptostreptococcus, Bacillus fragilis and Pseudomonas. Rarely, Actinomyces is involved in this process. In this case report, we report a case of actinomycosis of the appendix vermiformis occurring in a 19-year-old male with no predisposing factors. Along with a review of the literature, we will define the risk factors, clinical characteristics, diagnostic methods, and treatment of actinomycosis.

Appendicular inflammation can present as a discharging fistula on the abdominal wall. We are reporting a rare case of appendico - cutaneous fistula presenting as a large wound over the right iliac region. A 60 year old female reported to the emergency with a large wound and slough on right side of the abdomen. The thin shinning serous discharge from the wound revealed actinomycosis on microbiology. Patient was successfully treated conservatively with the help of percutaneous drainage and antibiotics. On follow-up of 3 months, patient is doing well and is asymptomatic. Acute appendicitis is considered one of the elementals of general surgical disease processes, yet its presentation often confounds its diagnosis by most surgeons. Its presentation as abscess in the abdominal wall and groin is a rare clinical entity. Because of insidious onset and subtle clinical signs of resulting abscess, the diagnosis of such cases is often delayed. USG and Contrast enhanced computed tomography are important part of investigations to make diagnose and helps in the treatment.

The authors present three cases of abdominal actinomycosis that were initially diagnosed as acute appendicitis, an abscess in the left groin and pelvic tumour, probably of gynaecological origin. Definitive diagnosis of abdominal actinomycosis was established as late as postoperatively. Abdominal actinomycosis is a chronic, infectious disease characterized most frequently by non-specific symptoms such as abdominal pain, fever, vomiting, bowel obstruction, weight loss, sometimes palpable resistance, and leukocytosis [1-9]. Diagnosis may be difficult and needs to be taken into account, especially in patients with risk factors.

A 52-year-old Hispanic woman presented to the emergency department, reporting worsening sharp lower right quadrant abdominal pain for 3 days. CT of the abdomen and pelvis showed evidence of inflammation in the peritoneal soft tissues adjacent to an enlarged and thick-walled appendix, an appendicolith, no abscess formation and a slightly thickened caecum consistent with acute appendicitis. During laparoscopic appendectomy, the caecum was noted to be firm, raising suspicion of malignancy. Surgical oncology team was consulted and open laparotomy with right hemicolectomy was performed. Pathology reported that the ileocaecal mass was not a malignancy but was, rather, actinomycosis. The patient was discharged after 10 days of intravenous antibiotics in the hospital, with the diagnosis of abdominal actinomycosis. Although the original clinical and radiological findings in this case were highly suggestive of acute appendicitis, abdominal actinomycosis should be in the differential for right lower quadrant pain as it may be treated non-operatively.

Numerous parasitic infections can cause inflammation of the appendix and can mimic appendicitis clinically. The diagnosis is generally achieved only after surgery. However early diagnosis through stool examination may prevent life-threatening complications. This study investigated the presence of parasitic infections in surgically removed appendices as an etiology of acute appendicitis. A retrospective study included patients who had undergone surgery for acute appendicitis over a period of three years from Jan 2012 to Dec 2014. Demographic data, laboratory investigations, operative data and pathological findings, presence and type of parasites were retrieved. The results showed that out of 1536 patients with appendectomy done, 938 (61.1%) were males and 598 (38.9%) were females. Parasitic infection was demonstrated only in 0.4% (6 patients). Mean average age of these patients was 12 years. Enterobius vennicularis was present in 4 patients (66% of the parasitic affection) and Schistosoma mansoni in 2 patients (34% of the parasitic affection). Other etiologies were acute suppurative appendicitis (94.1%), chronic appendicitis (3.1%), tumors (0.3%), tuberculosis (0.2%) and actinomycosis (0.1%). Appendix was found normal in 2% of patients underwent appendectomy.
