[Fibrous tumor of the pleura].

Pleural fibroma, or fibrous tumor of the pleura, is an uncommon entity which is characterized by slow proliferation of undifferentiated, intermediary or mature fibroblasts associated with collagen fibers forming a tumor stroma. We report a case in a 49-Year-old man who developed exercise-induced dyspnea and right chest pain. The thoracic CT scan revealed the presence of a mass in the right lung base composed of heterogeneous encapsulated tIssue. Tumor resection was performed leading to the histological diagnosis of pleural fibroma. Immunohistochemistry tests revealed positive vimetin and CD34, and negative cytokeratin uptake. These immunohistochemistry data contributed to the differential diagnosis with malignant pleural mesothelium. Pleural fibroma is a benign tumor in 80% of the cases. Prognosis is excellent. Local recurrence is exceptional and generally occurs after incomplete resection. Radial surgical treatment determines the prognosis and is required to prevent local recurrence. Other criteria of malignancy are not correlated with the clinical course of this type of tumor.

[Gallbladder tuberculosis associated with cholelithiasis].

Tuberculosis of the gallbladder is rare, even in our country known for being an endemic area. The positive diagnosis depends on suspicion of tuberculosis, peroperative findings and histological examination. From a review of the literature, the physiopathology of this infection is discussed, emphasizing the role of lithiasis in the development of tuberculous lesions. The authors report a case of gallbladder tuberculosis in a female patient who presented with a clinical picture of chronic cholelithiasis. The diagnosis of gallbladder tuberculosis was reached only after surgery and proven by histopathology. In our case, the presence of stones associated with non specific inflammatory alterations and possibly low resistance against tubercle bacillus, is believed to have been of importance for the development of the tuberculous infection.

[Pulmonary metastasis from a glioblastoma. A case report].

Glioblastoma is a primary malignant astrocyte tumor of the central nervous system. Extraneural metastasis is uncommon. We report a case of spontaneous lung metastasis from a glioblastoma without prior surgery. Positive diagnosis was achieved from histology and immunohistochemistry

[Hydatidosis: apropos of several uncommon locations].

Most hydatid cysts are found in the liver or lungs but occurrence in other locations is possible. The purpose of this report is to describe three cases involving cysts locate in the ovary, joint, and thyroid. Clinical findings associated with these uncommon locations were poorly specific and diagnosis required histological examination after surgical exploration. Imaging and serology were useful to differentiate hydatid cyst from benign or malignant tumor disease but often failed to achieve definitive differential diagnosis. Thorough investigation is necessary to rule out more common locations in the liver or lung. Continued surveillance is needed for early detection of recurrence. Preventive campaigns are necessary in endemic areas, such as Morocco.

[Intra-abdominal desmoplastic small round cell tumor. A case report].

Intra-abdominal desmoplastic small round cell tumor is an extremely rare and aggressive neoplasm that predominantly occurs in young adult men; it has an uncertain histogenesis, and predominant or exclusive intra-abdominal localisation without visceral origin involvement. This tumor is characterized by its distinct morphology and its multiphenotypic differentiation. We report a case of an intra-abdominal desmoplastic round cell tumor in a 24 years old woman. In the light of this case, the clinical morphological immunohistochemical and molecular of this rare desease are revewed.
