Granular cell tumor of the lung and tracheobronchial tree: Two case-presentation with a review of the literature.

Pulmonary granular cells tumors (CGT) are rare tumors, that derive from Schwann cells. In the tracheobronchial and pulmonary tree, they remain a diagnostic challenge. There are no well-established criteria to differentiate between benign, atypical, and malignant GCT.

Mediastinal cysts : a 52-case retrospective study.

Introduction: mediastinal cysts are rare lesions developed from mediastinal structures. They may be acquired like thoracic duct cysts or lymphangiomas or congenital like the bronchogenic cysts, enteric cysts or celomic cysts. These cysts are rare and may cause diagnostic challenges.

Tuberculosis of the Thyroid Gland Presented as a Rapid Enlargement of a Preexisting Goiter.

Thyroid involvement with tuberculosis is an uncommon condition even in endemic countries. As its clinical presentation is not specific, diagnosis is often difficult and requires histopathological confirmation. Herein we report an observation of secondary tuberculosis of the thyroid gland in a woman with a type 2 diabetes mellitus and a primary hypothyroidism.

Sub-cutaneous histiocytic sarcoma in a child: a case report.

Background: Histiocytic sarcoma (HS) is a rare hematologic malignancy with morphologic and immunophenotypic evidence of histiocytic differentiation. This tumor follows an aggressive clinical course.

Case Presentation: We report the case of a 14 year-old white girl who presented with a nodular lesion in the thigh, involving the skin and soft tissue.

[Multicentric tubulopapillary carcinoma of the kidney associated with renal adenomatosis].

Tubulopapillary tumors of the kidney represent a particular group of the renal tumors. They cover a continuous spectrum of tumors ranging from the adenoma to the renal cells papillary carcinoma. The histological and immunohistochemical similarities, as well as the high recurrence of the association of these two entities suggest a continuity of the same biological process.

Malignant glomus tumor of trachea: a case report with literature review.

Glomus tumors of the trachea are extremely rare and generally benign, with very few cases of malignant transformation reported in literature. We present the case of a 74-year-old man explored for cough and dyspnea. Bronchoscopy showed a polypoid mass arising from the posterolateral tracheal wall.

[Fatal pulmonary mycosis in a diabetic and cirrhotic patient].

Pulmonary mucormycosis is a rare, devastating, opportunistic fungal infection, caused by the ubiquitous filamentous fungi of the Mucorales order of the class of Zygomycetes. This infection occurs principally in some particular conditions, specially in diabetic patients and immunocompromised host, and rarely in cirrhotic patients. The diagnosis of mucormycosis can only be confirmed by pathological and mycological examination of biopsy specimens.

Elastofibroma of scapula: a case report and literature review.

Elastofibromas are benign soft tissue tumors. They occur mostly in the infrascapular region between the thoracic wall, the serratus anterior and the latissimus dorsi muscle, with a prevalence of up to 24% in the elderly. The etiology of this lesion remains uncertain and is a source of ongoing debate.

Malignant phyllodes tumor of the breast with liposarcomatous differentiation and intraductal hyperplasia.

Phyllodes tumor of the breast is a biphasic fibroepithelial neoplasm. 10 to 20% of phyllodes tumor show malignant transformation, often in the form of stroma, which usually shows fibrosarcomatous differentiation and rarely heterologous sarcomatous elements. Liposarcomatous differentiation is not common among phyllodes tumors.

Surgery in thoracic actinomycosis.

Background: Diagnosis and treatment of thoracic actinomycosis is difficult. In most cases, surgery is performed to rule out lung cancer or to control severe symptoms such as hemoptysis.

Methods: 6 patients with a mean age of 42 years underwent pulmonary resection and were given a pathologic diagnosis of thoracic actinomycosis at our institution between 2003 and 2010.

[Pulmonary atinomycosis: a great clinical polymorphism].

Background: Pulmonary actinomycosis is a rare bacteriological disease, caracterized by local suppuration and an extensive fibroinflammatory process, with a possible pseudotumoral outcome.

Aim: To report a new observation of a pulmonary actinomycosis.

Case Report: A 52-year-old patient, smoker, admitted in our department for infectious pneumopathy complicated by purulent pleurisy.

Benign myoepithelioma of the lung - a case report and review of the literature.

Introduction: Benign myoepithelioma is extremely rare in the lung, to the best of our knowledge; only five cases have been reported in the literature.

Case Report: An 18-years woman complained from tiredness and fever during four months. Laboratory findings and fibroscopies were normal.

Castleman's disease: an intrapulmonary form with intrafissural development.

Castleman's disease (CD) is an uncommon, mainly benign, lymphoproliferative disorder of unknown etiology, mostly involving the mediastinum. Parenchymal lung involvement of the disease is exceedingly rare. We describe a case of CD in a 23-year-old woman with a 4-year history of recurring dyspnea and nonproductive cough, whose chest X-ray showed an abnormal shadow of the right hilum.

Bronchoalveolar lavage impact in sarcoidosis: study of 40 cases.

Introduction: Studies on bronchoalveolar lavage (BAL) fluid samples profile characteristics in sarcoidosis patients hitherto reported in literature give rise to conflicting data. The typical finding is lymphocytic alveolitis with a high CD4/CD8 ratio, although a broad range of values has been found. THE AIM of the study was to evaluate different parameters of BAL fluid in patients with sarcoidosis before and after corticosteroid treatment and to determine the reliability of BAL in evaluating prognosis of sarcoidosis.

Posterior mediastinal paragangliomas: a report of three patients with peculiar tumours.

Paragangliomas of the mediastinum are rare neoplasms, representing less than 0.3% of mediastinal tumours and less than 2% of all paragangliomas. To date, no definitive morphologic criteria exist that correlate with the clinical outcome of these tumours.

Pulmonary blastomycosis: a case from Africa.

Pulmonary blastomycosis is an uncommon pathologic condition that is quite rare in Africa compared to endemic regions of Canada and the upper Midwest of the U.S. We describe a 45-year-old patient who complained of productive cough, hemoptysis, and dorsal rachiodynia.
