    <p>Abstract</p> <p>Introduction</p> <p>There are few case reports of thymoma with a thymic cyst. Such an association renders it difficult for any pathologist to differentiate from other neoplasms, such as a cystic thymoma.</p> <p>Case presentation</p> <p>A 50-year-old Berber woman from Morocco was admitted with a chronic cough of more than 10 years duration. Her medical history and physical examination were normal. Anterior chest radiography demonstrated a calcified opacity in her right anterior mediastinum. A chest-computed tomogram revealed a round cystic tumor, with significant calcification in her right anterior mediastinum. A surgical exploration was performed. The tumor seemed to be a well-encapsulated and totally calcified lesion, arising from the right lobe of her thymus. It was removed by partial resection of her thymus. Through histology, the calcified tumor exhibited some areas of multilocular fibrous-wall cysts. These cysts were partially lined by small cuboidal cells with severe chronic inflammation and an AB thymoma that arose from the wall of the cyst.</p> <p>Conclusion</p> <p>Greater attention should be given to multilocular thymic cysts, to exclude the possibility of neoplasm, especially when the cyst wall is thickened.</p

    A gallbladder tumor revealing metastatic clear cell renal carcinoma: report of case and review of literature

    No full text
    Abstract Metastatic renal cell carcinoma in the gallbladder is extremely rare, with reported frequencies of less than 0.6% in large autopsy reviews. Only 40 cases were reported in the literature. We report a first case of gallbladder polypoid tumor revealing metastatic clear cell renal cell carcinoma, which demonstrates the importance of radiological tests, histology and immunohistochemistry when making a definitive diagnosis. These examinations also allow differentiating metastatic clear cell renal cell carcinoma from other polypoid lesions in the gallbladder with clear cell morphology. Cholecystectomy should be performed to obtain a definitive diagnosis and to improve survival in case of solitary metastatic renal cell carcinoma.

    Primary solitary fibrous tumor of the retroperitoneum

    No full text
    Solitary fibrous tumor is an uncommon neoplasm affecting adults and typically located in the pleura and can also occur in a large number of other extra thoracic sites. We present the case of a solitary fibrous tumor (SFT) of the retroperitoneum and describe their histopathological and immunohistochemical features. The identification of SFT in the retroperitoneum is of importance because its clinico-pathological behaviour is still unclear. The pathologist plays a fundamental role in establishing both the positive and differential diagnosis
