BACKGROUND The occurrence of second primary neoplasms in patients with head and neck carcinoma assumes greater importance as our ability to control local disease improves. Both the primary lesions and the therapeutic interventions can predispose patients to pulmonary complications. OBJECTIVE To explore the incidence of pulmonary complications in patients with head and neck cancer who also und...

INTRODUCTION Perivascular epitheloid cell tumours are rare mesenchymal neoplasms characterized by a proliferation of perivascular cells with an epitheloid phenotype and expression of myomelanocytic markers. CASE PRESENTATION Here we present the case of a cystic perivascular epitheloid cell tumour of the retroperitoneum associated with multifocal lung lesions. A 27-year-old woman underwent lap...

BACKGROUND Glomus tumours are neoplasms arising from cells of the neuromyoarterial glomus bodies, which almost always occur in a subungual location. A lung location is extremely rare, with few cases reported in the literature. CLINICAL CASE The case is presented of a 33 year-old male, with non-productive cough, dyspnoea at rest, intermittent fever, and mild pain in rib cage. A chest radiograp...

Gastrointestinal stromal tumors (GISTs) are rare neoplasms of the gastrointestinal tract. Their incidence in the esophagus is 1%-3%. Never has a GIST been documented to directly invade the lung. We report a primary esophageal GIST with direct invasion into the lung parenchyma, presenting predominantly with respiratory symptoms. We include a retrospective literature review. Although the principl...

Malignant fibrous histiocytoma (MFH) cases are classified within the group of nonclassified sarcomas. The etiopathogenesis is unclear; however, MFH commonly develops in scar tissue and in areas exposed to radiation. MFH is the most common soft tissue sarcoma in adults and may be borne in the lungs, chest wall, mediastinum, or other tissues. Primary MFH of the lung constitutes less than 0.2% of ...

Malignant tumors frequently exhibit characteristic patterns of metastatic spread. In the rabbit, the VX2 carcinoma metastasizes to the lung, whereas the Brown-Pearce carcinoma usually spreads to organs distal to this structure. A system of in vivo micros copy has been established in which the response of the microcirculation of the lung has been observed during embolization of tumor cells from ...

We describe a 72-year-old man who presented with left hemiparesis due to acute cerebral infarction in the right fronto-temporal lobe. Three months prior to admission, he was hospitalized for right hemiparesis due to the acute cerebral infarction in the left anterior cerebral artery territory. To investigate the cause of his recurrent embolic event, a chest computed tomography scan and echocardi...

AU lung abscesses, a total of 95 cases, diagnosed at the Milwaukee County General Hospital from January, 1950, through December, 1958, were reviewed. The incidence remained constant during these years. Excluded were cases of minute embolic lung abscesses, bronchiectasis, tuberculous cavities, infected congenital cysts, hydatid cysts, and abscesses due to central necrosis of extensive neoplasms....

Pulmonary sequestration is defined as a mass of lung tissue separated from the tracheobronchial tree and irrigated by an anomalous systemic artery. It is rarely seen in conjunction with lung neoplasms. We report the case of a 39-year-old female patient diagnosed with a carcinoid tumor, located in the intermediate bronchus and accompanied by bronchiectasis in the right lower lobe. The patient un...

An epithelioid trophoblastic tumor (ETT) is a form of gestational trophoblastic neoplasms that arise from trophoblasts. The tumor generally occurs in women of reproductive age and has a characteristic growth pattern and immunohistochemical profile. We present an extremely rare case of a primary ETT occurring in the lungs with an adenocarcinoma in the contralateral lung as synchronous double pri...
