[Intracardiac lipoma revealed by arrhythmia]. / Arythmie cardiaque révélant un lipome intracardiaque.

Cardiac tIssue is a very rare localization for benign lipoma. Interseptal lipoma and lipomatous hypertrophy of the interatrial septum are two distinguished entities. We report the case of a 58-year-old patient who developed lipomatous hypertrophy of the interatrial septum which was revealed by arrhythmia. Diagnosis was suspected at magnetic resonance imaging and was confirmed intraoperatively and histologically.

[Tuberculous meningitis with pituitary abscess]. / Méningite tuberculeuse avec abcès hypophysaire.

Although rare, the possibility of pituitary tuberculoma should be considered in the diagnosis of non-pituitary intrasellar masses, especially in an endemic area and if radiologic imaging shows pituitary stalk thickening. We describe the case of a 52-year-old patient who presented tuberculous meningitis complicated by a pituitary abscess. He was treated with antituberculous drugs. The follow-up MRI 16 and 48 months later showed the decreased size of the pituitary mass. Radiological features and a review of the literature of pituitary tuberculoma are briefly discussed.

Adrenal adenoma in a patient with Gardner's syndrome. A case report.

Gardner's syndrome is an autosomal dominant condition characterized by multiple colorectal polyposis associated with various soft and hard tissue tumors. We report a case of adrenal adenoma in a 37-year-old woman with Gardner's syndrome. Although extraintestinal neoplasms, particularly adrenal lesions, are a rare association, an increased awareness is important.

[Rosai-Dorfman disease with orbital and rhinopharyngeal localizations. A case report]. / Maladie de Rosai-Dorfman. A propos d'une localisation orbitaire et rhinopharyngée.

OBJECTIVES: We present a case report of Rosai-Dorfman disease with multiple extranodal involvement and favorable outcome after steroid therapy. MATERIAL AND METHODS: Rosai-Dorfman disease was diagnosed in a 17-year-old man with orbital, lacrymal, and rhinopharyngeal localizations. Histopathologic examination of lymphadenopathy biopsy revealed the diagnostic of Rosai-Dorfman disease. We present the histological findings leading to diagnosis and radiological data. RESULTS: Conservative treatment with oral steroids resulted in the resolution of cervical lymphadenopathy and extranodal lesions. The patient was free of problems nine mouths after discontinuation of his treatment, demonstrating its efficacy and safety. CONCLUSION: Rosai-Dorfman disease is a benign disorder and steroid treatment must be initiated in cases with significant cosmetic deformity.

[Lymphocytic hypophysitis]. / Hypophysite lymphocytaire.

Lymphocytic hypophysitis is a rare inflammatory disease of the pituitary gland which may be related to an autoimmune process. Only twenty cases are reported in male. Patients usually present with symptoms of an expanding intrasellar mass or varying degrees of hypopituitarism. Most of the cases are misconsidered preoperatively as pituitary adenomas. We report a case of lymphocytic hypophysitis which has occurred at a 37-year-old-man.
