Oesophageal cavernous haemangioma

Esophageal cavernous haemangioma is an uncommon benign neoplasm. These tumors are usually discovered incidentally as they are often asymptomatic. The symptoms, if present, are bleeding and dysphagia. Endoscopic and radiographic features are nonspecific and histopathologic examination is required for definitive diagnosis and appropriate treatment. We herein report a case of a 69-year old man who presented with complain of mild dysphagia for solid foods. Endoscopic evaluation with transesophageal ultrasonography and CT revealed a 5 cm intramural tumor in the posterior wall of the upper esophagus. The tumor was resected and histological examination showed an esophageal cavernous haemangioma.

Synchronous occurrence of pulmonary adenocarcinoma and pleural diffuse malignant mesothelioma

We report a rare case of diffuse malignant pleural mesothelioma synchronous with a localized adenocarcinoma of lung in a 68-year old man with a suspicious history of asbestos exposure. Computed tomography revealed a sub-pleural mass in the lower lobe and an irregular dense area of medium lobe of right lung with thickening of pleura encasing the lung parenchyma and homolateral pleural effusion 1 cm thick. The patient underwent surgery and a right medium and lower lobectomy was performed. Upon frozen sections, intraoperative diagnosis was adenocarcinoma with a poorly differentiated component of lung infiltrating the pleura. The postoperative histological definitive diagnosis with an important contribution of immunostaining was synchronous pulmonary adenocarcinoma and pleural diffuse malignant epithelioid mesothelioma.

Pure uterine lipoma

Pure uterine lipoma is a very rare benign mesenchymal neoplasm, and only a few cases have been reported in the literature. This is in contrast to leiomyoma, which is not only the most common neoplasm of the uterus but also one of the most common tumours in women, estimated to occur in 20-40% of women beyond the age of 30 years (AFIP) and more frequently affect postmenopausal women. We report the case of a 70-year-old woman who presented with pelvic pain and postmenopausal uterine bleeding. Pure uterine lipoma was diagnosed preoperatively by CT scan with and without contrast and confirmed postoperatively by pathological examination. Clinical and histological diagnosis of pure uterine lipoma with immunohistochemical findings are described,and the efficacy of CT in diagnosing this tumour is discussed.

Cervical lymph node metastasis of adenocarcinoma of prostatic origin

Cervical nodes metastases generally arise from carcinomas of the head and neck, but also from other organs. This report describes a case with metastatic prostate cancer in the cervical lymph node.

Incidental finding of peripheral B-cell non-Hodgkin lymphoma, lymphocytic/CLL type, of the gallbladder in a patient with chronic cholecystitis

Although lymphoma involvement of the gallbladder, especially by MALT and large-cell types, is rare, this possibility should be considered in patients with symptoms of acute cholecystitis. A cholecystectomy was performed in a 79-year-old male patient with a clinical diagnosis of chronic cholecystitis. Histologically, the specimen showed an incidental finding of a small lymphocytic lymphoma (CLL) by morphologic and immunophenotyping studies, subsequently confirmed with flow cytometric analysis of blood. During follow-up, multiple lymph node enlargement was detected. An axillary node, excised and submitted to our department, was positive for lymphoma involvement. The bone marrow was negative.
