1/166. Papillary endothelial hyperplasia presenting as a chest wall neoplasm.Soft tissue hematomas generally resolve but may persist and develop into slow-growing, organized masses. These chronic expanding hematomas are characterized by a pseudocapsule and a predominantly necrotic central cavity, with foci of newly formed capillaries. These have been called chronic expanding hematomas or Masson's papillary endothelial hyperplasia. These lesions can mimic vascular neoplasms and must be considered in the evaluation of expanding soft tissue vascular malformations.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
2/166. Surgical resection combined with intrathoracic hyperthermic perfusion for thymic carcinoma with an intrathoracic disseminated lesion: a case report.Thymic undifferentiated carcinoma has a poor prognosis. We encountered a patient with thymic carcinoma associated with an intrathoracic disseminated lesion, who underwent surgery combined with intrathoracic hyperthermic perfusion after systemic chemotherapy and showed good results. The 45-year-old man was diagnosed as having a thymoma with an intrathoracic disseminated lesion. After he underwent three courses of systemic chemotherapy, he was admitted to our hospital. An anterior mediastinal tumor and an intrathoracic disseminated lesion remained, and were treated by surgical resection combined with intrathoracic hyperthermic perfusion. The tumors were histopathologically diagnosed as thymic undifferentiated carcinomas with pleural dissemination. At present, approximately 16 months after surgery, the patient is alive without recurrence.- - - - - - - - - - ranking = 7.2187277088218keywords = carcinoma, undifferentiated (Clic here for more details about this article) |
3/166. Primary posterior chest wall echinococcosis.Hydatid cyst is not mentioned among the chest wall tumours in areas not known to harbour echinococcosis. One of the uncommon sites for echinococcosis even in endemic countries is the chest wall. The striking resemblance between neoplasm and hydatid cysts forms a diagnostic dilemma and makes the correct diagnosis essential before surgery.- - - - - - - - - - ranking = 0.2keywords = neoplasm (Clic here for more details about this article) |
4/166. rhabdomyosarcoma in a child with massive pleural effusion: cytological diagnosis from pleural fluid.We report on a case of embryonal rhabdomyosarcoma in an 11-yr-old boy investigated for mild chest pain after trauma. Chest radiography showed a massive right pleural effusion. Cytological analysis of the pleural fluid demonstrated the presence of malignant small undifferentiated cells. The rhabdomyoblastic nature of the cells was confirmed by positive immunostains of HHf35 actin, desmin, and skeletal muscle myosin; histological examination of a core biopsy confirmed the diagnosis of rhabdomyosarcoma. Computed tomography and gallium scan revealed the presence of an extensive anterior and lower chest wall mass involving the mediastinum, as well as retroperitoneal lymphadenopathy. Massive pleural effusion is a frequent presentation in malignant disease, but is rare in rhabdomyosarcoma. The immunochemical stain studies performed on cytological smears in this case proved to be very useful for making the definitive and accurate diagnosis. Diagn.

5/166. Desmoid tumor of the chest wall following chest surgery: report of a case.Desmoid tumors of the chest wall following chest surgery are a rare occurrence. A case of this disease is reported herein together with a review of the literature. A 74-year-old man, who had previously undergone a right lower lobectomy for squamous cell carcinoma of the lung, was referred to our hospital with an abnormal shadow on his chest X-ray. The tumor, located in the right lateral chest wall, was successfully resected by an aggressive, wide extirpation, and a final diagnosis of a desmoid tumor originating in the chest wall was made. When following up patients after surgery for lung cancer, the possibility of desmoid tumors developing in the incised chest wall should therefore be kept in mind.- - - - - - - - - - ranking = 0.99950505698083keywords = carcinoma (Clic here for more details about this article) |
6/166. Chest wall recurrence of breast cancer detected by scintimammography.A case of chest wall recurrence of breast cancer detected by scintimammography is presented. A 63-year-old woman who had a right mastectomy for breast carcinoma 24 years earlier was evaluated for left axillary adenopathy. Although it was suspected that a second primary malignancy had developed in the left breast, results of mammography and magnetic resonance imaging of that breast were negative. Scintimammography performed with Tc-99m sestamibi confirmed a normal left breast but revealed a lesion in the right chest wall at the site of the previous mastectomy. This was surgically confirmed as recurrent breast carcinoma, which subsequently altered patient management.- - - - - - - - - - ranking = 1.9990101139617keywords = carcinoma (Clic here for more details about this article) |
7/166. The cytomorphology of pleuropulmonary blastoma.Pleuropulmonary blastoma is a rare, primitive primary neoplasm of the thorax in young children. The tumor, which is often but not always associated with cystic lung lesions, may arise in pulmonary parenchyma, the mediastinum, and pleura. Histologically, it is characterized by a biphasic neoplastic population of undifferentiated-appearing small round cells and larger spindle-shaped cells. A proportion of these cancers may also manifest more specific mesenchymal differentiation. In contrast to the pulmonary blastoma of adults, a malignant epithelial component does not occur. We present herein the third known case of a fine needle aspiration biopsy of a pleuropulmonary blastoma in a 5-year-old girl. The smears were moderately cellular and included an admixture of the characteristic small ovoid blastemal elements and scattered spindled mesenchymal tumor cells.- - - - - - - - - - ranking = 0.31109615497802keywords = neoplasm, undifferentiated (Clic here for more details about this article) |
8/166. Cutaneous metastasis of chordoma.BACKGROUND: Chordomas are rare neoplasms that arise from the notochord remnant. They develop in the sacrococcygeal (50%) or cervical (15%) region and are generally regarded as a locally aggressive tumor with a slow progressive growth rate and a metastatic incidence ranging from 3 to 48%. skin involvement by chordoma is rare, but can occur by direct extension, by local recurrence and by metastases. OBJECTIVE: To illustrate by a case report the clinical presentation and management of this disease. methods: We present a case of sacral chordoma with metastases over a 10-year period to the lungs, the soft tissue of the chest wall, the triceps tendon, and distant cutaneous metastases to the back and the nose. RESULTS: The cutaneous metastases were treated by excision. CONCLUSION: chordoma is a slow growing tumor of the notochord remnant that may metastasize to the skin. physicians and pathologists should be aware of this entity.- - - - - - - - - - ranking = 0.2keywords = neoplasm (Clic here for more details about this article) |
9/166. Rib metastasis revealing hepatocellular carcinoma.Bone metastasis infrequently appears as the first manifestation of hepatocellular calcinoma (HCC), and in any case in most patients the primary tumour is detected a few months after its development. We report the case of a patient with alcoholic liver disease, increased levels of alpha-fetoprotein, and no evidence of hepatic lesion in the different imaging modalities, in whom metastasis of HCC was detected in the ribs, whereas the primary tumour was not diagnosed until 15 months later. We believe that all patients with increased levels of alpha-fetoprotein should be tested in an intensified search for HCC and possible metastases, given that hepatic lesions may not be detected until many months alter the diagnosis of metastatic disease.- - - - - - - - - - ranking = 3.9980202279233keywords = carcinoma (Clic here for more details about this article) |
10/166. thoracic wall lipoblastoma: a case report and review of histopathology and cytogenetics.A rare case of a successfully excised intra- and extrathoracic lipoblastoma of the anterior chest wall in a 13-month-old female infant is reported. Histopathology and cytogenetical analysis established the diagnosis of a lipoblastoma. The differential diagnosis, histology and cytogenetical evaluation of lipomatous neoplasms are discussed. Karyotypic analysis may be of use in diagnostically difficult cases owing to the characteristic alterations in 18q11-13. A complete resection of lipoblastomas is feasible and advantageous with no need for a mutilating radical excision.- - - - - - - - - - ranking = 0.2keywords = neoplasm (Clic here for more details about this article) |
