“…Mycobacterium avium intracellulare (MAI) was detected in a spindle cell pseudotumor of the brain in a patient receiving steroid therapy for treatment of sarcoidosis [19]. Other organisms found in systemic PCG include CMV, mycobacteria, listeria, and actinomyces [2,4,7,8,20,21]. Other concomitant diseases have been described with PCG.…”

Plasma cell granuloma (PCG) is an uncommon non-neoplastic mass lesion of unknown etiology. It is characterized by a polyclonal proliferation of chronic inflammatory cells, mostly mature plasma and other mononuclear cells. PCGs arising in the central nervous system are particularly rare. We report two additional cases of intracranial PCG exclusively involving the brain parenchyma. A 47 year-old woman, presenting with partial motor seizures and fluent aphasia, underwent complete excision of a well-demarcated, enhancing left parietal mass. The second patient was a 56 year-old man presenting with headaches and right-sided weakness who underwent stereotactic biopsy of an ill-defined, heterogeneously enhancing lesion in the left basal ganglia. Immunohistochemical analysis of surgical specimens showed polyclonal plasma cells and mature lymphocytes but no etiological agent. A histopathologic diagnosis of intracranial PCG was made in both cases. PCG should be part of the differential diagnosis of enhancing mass lesions of the brain. The etiology and natural history of these tumor-like lesions is not fully understood. Complete surgical excision appears to be curative. Lesions where total resection is not possible may benefit from adjuvant treatment including corticosteroids and possibly radiation therapy.

“…PCG was first described by Bahadori and Liebow in the lung [2]. It occurs most frequently in the upper respiratory tract, liver, spleen, stomach, thyroid gland, lymph nodes, and heart [3,4]. In rare cases, the central nervous system may be involved [5,6].…”

“…In our case, the abscess fistulated into the urinary bladder and omentum. Some predisposing events are: appendicitis, diverticulitis, perforated gastric ulcers, previous bowel surgery, cholecystectomy, pancreatitis, endoscopic manipulation, trauma, immunosuppression and loss of gallstones after laparoscopic cholecystectomy [3,4,[9][10][11][12] . Actinomycosis abscess can affect the colon, ileum, uterus and tract, liver, abdominal wall, pancreas, greater omentum, retroperitoneum and kidney.…”

Abdominal wall actinomycosis is a rare disease frequently associated with the presence of an intra uterine device. We report on a case of a 47-year-old woman who had used an intrauterine device for many years and had removed it about a month prior to the identification of an abdominal wall abscess caused by Actinomyces israelii . The abscess mimicked a malignancy and the patient underwent a demolitive surgical treatment. The diagnosis was obtained only after histopathological examination. Postoperatively, the patient developed an infection of the wound which was treated with daily medication. The combination of long-term high dose antibiotic therapy with surgery led to successful treatment.
