We report a case of cerebral aspergillosis in a 39-year-old woman with a history of treated chronic lymphocytic leukemia (CLL). Multiple fragments of fixed tissues with formalin were freshly sent to the laboratory. An extemporaneous examination was performed by spreading. The rest of the sample was embedded in paraffin and studied according to the standard histological method with special stains and an immunohistochemical study. A microscopic observation showed abundant clusters of tangled mycelial filaments, Grocott+. At the edge, a nervous tissue was observed remodeled by an abundant inflammatory infiltrate consisting essentially of small lymphocytes and plasma cells. Additional immunohistochemistry was performed using anti-CD20, anti-CD3, anti-CD5, anti-CD23, anti-Bcl2, anti-Ki67, anti-IgD and anti-Kappa and Lamda antibodies. All taken together there were no further founding in support of a secondary localization of CLL. Cerebral aspergillosis is quite rare and often occurs in a context of immunosuppression. This case indicates the importance of a close collaboration between clinicians and pathologists for optimal patient care.展开更多

It can affect different segments of the digestive tract. Male patients over 50 years old seem to be more affected. Classically, one opposes the primary or idiopathic forms and the secondary forms. Case Report: We report the case of a 62-year-old female patient with a history of treated peptic ulcers, who presented with episodes of intermittent atypical abdominal pain that worsened abruptly. The physical examination revealed a surgical abdomen with tenderness to palpation. The patient underwent a jejunal resection. The pathological examination showed macroscopically an intestinal fragment with confluent subserosal and intestinal intraparietal bullae. On opening, the portion containing the bullae was thickened, infarcted, congestive, hemorrhagic, and brittle with narrowing of the intestinal lumen. The bullae are tense and leave serosities. On histological examination, the intestinal wall was very congestive with hemorrhagic patches of suffusion. There were optically empty cystic formations that do not communicate with the digestive lumen. The adjacent mucosa is the site of a moderate subacute inflammatory reaction. Conclusion: Pneumatosis cystoides intestinalis is a rare and usually benign pathology. The symptoms, when they exist, are not specific. Its physiopathology is still very much debated. The prognosis is generally good. The knowledge of this pathology is necessary to avoid invasive explorations and heavy treatment without interest for the patient.展开更多
