Primary hepatic actinomycosis is one of the chronic abscess-forming infections of the liver. Accurate diagnosis is frequently delayed due to its indolent course and nonspecific clinical and radiological manifestations. We report a case of a 57-year-old man presenting with asymptomatic multiple hepatic masses on follow-up abdominal computed tomography performed 1 year after stomach cancer surgery. Although a percutaneous liver biopsy procedure was conducted twice in order to obtain confirmative pathology, only a nonspecific organizing abscess with plasma cell infiltration was revealed, without identification of any organism in the tissue cultures. Ultimately, actinomycosis was diagnosed following the detection of sulfur granules on open surgical biopsied tissue. This case suggests that primary hepatic actinomycosis should be considered as one of the possible causes for enigmatic inflammatory lesions of the liver.

Here we report a case of 41-year-old man with a soft tissue density mass at right upper lung and palpable abscesses at right upper backside and right wrist. ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography demonstrated a 7.8 × 5.0 cm mass with soft-tissue density in the upper lobe of the right lung with high metabolic activity. The infiltrative mass extended to adjacent chest wall soft tissue. Final diagnosis of pulmonary actinomycosis with multiple abscesses was made. The patient responded well to antibiotics treatment.

The authors report a caruncular abscess caused by actinomycosis. A 47-year-old woman was admitted with persistent purulent discharge from the caruncle of the left eye for a duration of six months. Excisional drainage was performed, and 'sulfur granules' were observed, consistent with actinomyces infection. Intraoperative lacrimal probing and irrigation were performed to confirm that the abscess and canaliculus were not connected. Oral and topical antibiotics were administered postoperatively; the lesion resolved with no evidence of recurrence, and the symptom improved.

The patient presented with right nasal obstruction, purulent secretion in nasal meatus and dull headache for 3 years. A dark brown mass, irregular in shape, surface roughness and purulent secretion adherent, was seen in the nose, touched as coal tar stone. CT examination showed high density in the right nasal meatus. Postoperative pathological examination proved to be rhinolith and actinomycosis.

PURPOSE: Intrabdominal actinomycosis is difficult to diagnose preoperatively. This chronic infection has a propensity to mimic many other diseases and may present with a wide variety of symptoms. The aim of this study was to evaluate the characteristic clinical features with review of the literature. MATERIALS AND METHODS: We retrospectively analyzed 22 patients with intrabdominal actinomycosis between January 2000 and January 2006. RESULTS: There were two men and 20 women with a mean age of 42.8 years (range, 24 - 69). Twelve patients presented with masses or abdominal pain, whereas 3 patients presented with acute appendicitis. The rate of performing an emergency surgery was 50% due to symptoms of peritonitis. The mean size of tumor was 5.5 cm (range, 2.5 - 11.0). Sixty percent (n = 12) of female patients had intrauterine device (IUD). The average time to definite diagnosis was 10.6 days. CONCLUSION: Intrabdominal abdominal actinomycosis must first be suspected in any women with a history of current or recent IUD use who presents abdominal pain. If recognized preoperatively, a limited surgical procedure, may spare the patient from an extensive operation.

OBJECTIVETo find a fast and simple method for detection of specific pathogens in upper aerodigestive tract.

METHODSSixty-one cases of specific infections in upper aerodigestive tract encountered during a 10-year period in Beijing Tongren Hospital were retrospectively studied. Six histochemical stains, including PAS, Giemsa, Gram, methylene blue, modified Warthin-Starry and acid-fast stains were applied. The morphology of different pathogens was studied and the staining patterns were compared.

RESULTSThere were 23 cases of pharyngeal treponemal infection, 10 cases of short treponemal infection, 4 cases of mycobacterial infection, 4 cases of infection by rhinoscleroma bacilli, 1 case of sinonasal fungal infection, 1 case of combined infection of bacteria and Oidium albicans, 2 cases of tonsillar Actinomycetes and 16 cases of non-specific bacterial infections. Both pharyngeal treponemal infection and infection by rhinoscleroma bacilli could be detected by modified Warthin-Starry stain. As for sinonasal fungal infection, PAS, Giemsa and modified Warthin-Starry stains were useful in differentiating different types of fungi. Mycobacteria were best demonstrated by conventional acid-fast stain.

CONCLUSIONSSpecial histochemical stains performed on histologic sections are useful for diagnosing specific infections in upper aerodigestive tract.
