“…The patient was treated with penicillin and remained symptom-free. Kumar et al [8] reported the case of a 14-year-old boy who presented with a mass like a soft tissue neoplasm on the anterior aspect of the knee. After surgical removal, histological examination confirmed actinomycosis.…”

“…The infection occurred four years after acute appendicitis, likely through slow fistulisation. Kumar 12 described a particular case of a 14-year-old boy with an anterior distal thigh mass, superficial to the quadriceps, diagnosed as actinomycosis after surgical drainage. It is unclear how this patient sustained this infection in this very unusual location.…”

INTRODUCTIONActinomycosis is known to mimic several types of neoplasms, leading to morbid surgical interventions.PRESENTATION OF CASEWe report the particular case of an extensive right para-iliac actinomycetoma presenting as a sarcoma, which to our knowledge has not yet been described in the literature, in a patient with previous ruptured appendicitis. Thanks to the collaborative work between the orthopedic and general surgeons, pathologist and microbiologist, the diagnosis of actinomycosis was made pre-operatively, saving this 15-year-old patient from a tumor resection protocol.DISCUSSIONActinomycetomas have often been reported to present in the same way as several abdominal and gynecological neoplasms, and on rare occasions been described as mimicking other soft-tissue sarcomas, leading to unnecessary morbid tumor resection protocols. The most common cause of abdominal actinomycosis is perforated appendicitis, and may present several years later.CONCLUSIONWhile faced with a soft tissue mass transgressing tissue planes and possibly extending to the region of the right lower quadrant, especially with a history of previous perforated appendicitis, one should consider the possibility of an abscess caused by pathogens of intestinal origin, including the gram positive anaerobe Actinomycosis israelii. Failure to actively search for this pathogen, which is not detectable with routine staining techniques and may take up to 1–2 weeks to isolate, may lead to unnecessary morbid surgical procedures.

“…However, in patients who have a mediastinal mass and signs and symptoms including fever, malaise, anorexia, and chest pain, actinomycosis should remain on the list of differential diagnoses, especially if chest wall involvement or other manifestations of thoracic actinomycosis are present [10,[22][23][24]. On the figures we can see the perforation of oesophagus and the sign for inflammation and infiltration in the thoracic spacemen.…”

“…In summary, mediastinal actinomycosis, a very rare condition, has no pathognomonic findings on chest radiographs or CT scans [8,19,22,23].…”

A 48-year-old man with retrosternal chest pain and upper abdominal pain with propagation to the back, with clinical signs of nausea, dyspnea and dysphagia was referred to the Clinics of thoracic surgery. After esophagography, operative treatment was indicated. Left thoracotomy with mediastinothomy were performed. During the operation, a sample of pus was taken and sent for a microbiological examination at the Institute of Microbiology and Parasitology, Medical Faculty in Skopje. Standard microbiological procedures were used. The sample was cultured anaerobically on Schaedler agar and incubated for 48 hours at 37ºC. Oval, smooth colonies were observed. Gram stained smear revealed short branching Gram-positive filaments suspected for genus Actinomyces. For a definitive diagnosis and differentiation of the Actinomyces species, an automated VITEK system was used. Two weeks after treatment by ceftriaxon, metronidazol and analgetics, all clinical signs improved and patient was released in good physical condition.
