According to the author's findings in 80 of 125 patients under observation the development of abdominal actinomycosis was related with inflammation in the appendicular process, in 65 patients the former starting after appendectomy. In examination of 100 patients with diagnosis of acute appendicitis actinomycosis of the ileocecal region was diagnosed in 5 patients. Actinomycosis was spreading from the ileocecal region by contact in retroperitoneal cellular tissue in 23 cases, in the left iliac region--in 12, in the lesser pelvis--in 8.

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.

Actinomycosis is a rare infection which can attack most parts of the body, even in normal individuals. In the gastrointestinal tract it may imitate acute appendicitis, Crohn's disease or tumors. We present a young soldier with appendiceal involvement who was mistakenly operated on. Because of its very good response to antibiotics, this infection should be recognized early and treated, to prevent prolonged, unnecessary suffering.

A 43-year-old man, with a chief complaint of abdominal pain and a palpable mass in the lower abdomen, was admitted to this hospital. He had 2-3 episodes of diarrhea monthly for several years. Laparotomy revealed the mass resembling sarcoma, invaded the ileum and bladder and also it had disseminated lesions in the other intraabdominal organs. Resected tissues showed actinomycotic abscess. AB-PC was administered post-operatively, with a satisfactory prognosis. On the 71 patients with abdominal actinomycosis who underwent laparotomy during the past 32 years in Japan, 42 were males and 28 females. Many of them were in their forties or fifties. Some literatures mention the ileocecal region as the usual site of following perforated appendicitis. As far as this review is concerned, however, the transverse colon was as frequently affected as the ileocecal region and it was only in 13 patients that acute appendicitis preceded the infection. Abdominal actinomycosis is not an uncommon disease and should be taken into consideration in the differential diagnosis of the abdominal mass.

The authors describe in their case-study the history of a 25 years old woman, having the signs of acute abdomen. The patient underwent surgery, with the suspicion of acute appendicitis. It turned out, that the symptoms were due to the isolated actinomycosis of the greater omentum. The authors review the pathogenesis, the phenomenology, diagnosis and the therapy of this uncommon disease. They recommend to consider this special disease of the omentum, in the differential diagnosis of the appendicitis.

The acute abdomen in childhood is in most cases caused by an acute appendicitis and rarely it is secondary to other diseases. It is for that reason, that we present two cases extremely rare of acute abdomen: the first one was an abdominal Actinomycosis secondary to acute appendicitis that looked like a tumor and the second that was an acute omentitis due to pinworms.

The discovery of a tumour mass of the appendix, in an acute or chronic context, raises the problem of its benign or malignant, inflammatory or infectious nature. We report five cases of patients operated by the same surgical team between June 1991 and September 1996, who presented macroscopically and histologically with unusual appendicular pseudotumours: appendicular diverticulosis (n = 1), Crohn's disease localized to the appendix (n = 2), yersiniosis (n = 1), actinomycosis (n = 1). The preoperative diagnosis was acute appendicitis (n = 2) or tumour (n = 3). The postoperative course was uneventful in every case, and specific medical treatment was prescribed in two cases (yersiniosis and actinomycosis). These differential diagnoses must be considered in all appendicular diseases, but they are extremely difficult to confirm preoperatively.

Abdominal actinomycosis is a rare disease which often resembles an acute suppurative infection or/and abdominal tumour causing abscesses, fistulas and massive fibrosis. The preoperative diagnosis is difficult and surgical exploration is always needed because of major involvement of visceral and retroperitoneal structures. The disease can be diagnosed with certainty only on the basis of findings of bacterial colonies in histopathologic sections and typical sulphur grains in secretions from fistulas. The authors describe a case of abdominal actinomycosis involving the caecum and right colon, causing extensive retroperitoneal fibrosis and a fistula tract with an external cutaneous orifice at the level of the right iliac crest. These features resembled an acute appendicitis at first, and several surgical explorations were required before a correct diagnosis could be achieved. Abdominal actinomycosis can be treated by simple administration of antibiotics. With a correct diagnosis, medical therapy alone has proved effective in a substantial percentage of patients, thus avoiding the need for surgery, if important visceral or retroperitoneal structures are not involved. Abdominal actinomycosis always requires a careful differential diagnosis and must be considered in patients presenting abdominal tumours associated with abscesses and/or fistulas since early and efficient medical therapy, along with surgical intervention, where necessary, can lead to definitive recovery. Useful diagnostic tools are abdominal CT and selective FNAB.

The pathologic spectrum of the acutely inflamed appendix encompasses a wide range of infectious and noninfectious entities. The appendix suffers alone in some of these disorders, and in others may be involved through extension from other areas of the gastrointestinal tract. Although the appendix is the most commonly resected and examined intraabdominal organ, the pathogenesis and etiology of acute nonspecific appendicitis (the most common diagnosis made in this organ) remains enigmatic. This review encompasses the pathology, pathogenesis, and bacteriology of acute appendicitis, as well as controversial issues such as the diagnosis of chronic appendicitis and the significance of a morphologically unremarkable appendectomy specimen in the clinical context of appendicitis. In addition, the pathologic features, pertinent diagnostic techniques, and clinical significance of several specific bacterial, viral, fungal, and parasitic infections affecting the appendix are presented, including adenovirus, cytomegalovirus, Yersinia species, actinomycosis, Mycobacteria species, histoplasmosis, pinworms, schistosomiasis, and Strongyloides stercoralis.
