A 54-year-old woman with myoepithelioma, a very rare tumor of the lung, is reported. The patient presented with exertional dyspnea, cough and intermittent pleuritic chest pain. Her chest X-ray revealed a peripheral 2 cm mass in the left lower lung zone. Bronchoscopy was normal. She underwent thoracotomy in which a wedge-resection was performed. Histological examination of the specimen demonstrated myoepithelioma of the lung.

Metastases to the heart and pericardium are much more common than primary cardiac tumors and are generally associated with a poor prognosis. Tumors that are most likely to involve the heart and pericardium include cancers of the lung and breast, melanoma, and lymphoma. Tumor may involve the heart and pericardium by one of four pathways: retrograde lymphatic extension, hematogenous spread, direct contiguous extension, or transvenous extension. Metastatic involvement of the heart and pericardium may go unrecognized until autopsy. Impairment of cardiac function occurs in approximately 30% of patients and is usually attributable to pericardial effusion. The clinical presentation includes shortness of breath, which may be out of proportion to radiographic findings in patients with pericardial effusion or may be the result of associated pleural effusion. Patients may also present with cough, anterior thoracic pain, pleuritic chest pain, or peripheral edema. The differential diagnosis of pericardial effusion in a patient with known malignancy includes malignant pericardial effusion, radiation-induced pericarditis, drug-induced pericarditis, and idiopathic pericarditis. Any disease process that causes thickening or nodularity of the pericardium or myocardium or masses within the cardiac chambers can mimic metastatic disease.

In 1997, a 53-year-old male smoker was admitted for progressive shortness of breath associated with a productive cough and yellowish sputum, pleuritic chest pain, and low-grade fever. There was no history of trauma. A posterior-anterior chest radiograph showed a diffuse infiltrate through the right lung field and an air space parallel to the lateral border of the heart. A computed tomographic scan of the chest confirmed pneumopericardium, with no associated pericardial effusion. It also showed a cavitary infiltrate in the anterior basal segment of the right lower lobe, but no definite neoplasm. Cultures of the sputum grew Staphylococcus aureus. The patient had positive antibodies to human immunodeficiency virus (HIV), hepatitis A, and hepatitis B. A bronchial biopsy from the right lower lobe showed well differentiated infiltrating squamous cell carcinoma with an acute inflammatory exudate. No bronchopericardial fistula was noted. After antibiotic treatment, a repeat chest radiograph showed resolution of pneumopericardium and improvement of the chest infiltrate. Repeat computed tomography of the chest showed that the pneumopericardium had resolved, but now revealed a large pericardial effusion. No bronchopericardial fistula could be demonstrated. Unfortunately, our patient refused further investigation. Pneumopericardium is a rare disorder. In adults, pneumopericardium most commonly results from trauma. Although many other reports link pneumopericardium to an underlying disease process, our patient with HIV antibodies developed pneumopericardium despite having no history of trauma and no documentation of a communicating fistula. To our knowledge, there has been no previous report of pneumopericardium in association with acquired immunodeficiency syndrome.

Symptoms such as cough and hemoptysis in patients with lung cancer can be the consequence of local bronchopulmonary disease, tumor growth that leads to compression of surrounding structures, distant metastases, diverse systemic effects (anorexia, asthenia, weight loss), or paraneoplastic syndromes associated with tumor production of certain hormones. Approximately 10% of patients are asymptomatic at diagnosis. We report the case of a 77-year-old man with dyspnea, pleuritic chest pain, and lower limb edema. The patient died within a few days. The cause of the clinical picture was constrictive pericarditis secondary to metastases from lung carcinoma.

A 20-year-old man presented to our outpatient clinic with hemoptysis, cough, and pleuritic chest pain. His chest radiograph and pulmonary function tests (PFT) were normal. A bronchoscopy showed a small yellowish patch with a regular surface. A direct bronchoscopic biopsy was performed. The pathologic findings showed a benign granular cell tumor. The respiratory symptoms resolved after biopsying the tumor. On follow up, there were no signs of recurrence of the granular cell tumor after a period of 24 months.

Bronchogenic cysts are developmental foregut anomalies usually located within the mediastinum or lung parenchyma. An isolated bronchogenic cyst of the diaphragm is very rare. Our case was a 56-year-old female patient who presented with pleuritic chest pain in her right chest. Chest and abdominal computed tomography revealed a large lobulated cystic mass that was accompanied with pleural effusion in the right lower hemithorax. The tumor showed focally calcified areas in the wall and abutted against the diaphragm. We performed complete excision of the cyst including a portion of the diaphragm attached to it. The pathological diagnosis was established as the bronchogenic cyst originating from the diaphragm. We report this case with a review of the literature.

Details on the 28-year treatment history of a patient with an endocrine-responsive breast cancer are provided. She was originally diagnosed as having a T1N0M0 cancer after a modified radical mastectomy at age 41. Fifteen years later, in 1998, she presented with hemoptysis and pleuritic chest pain: a 10 cm right atrial tumor and estrogen receptor (ER) positive endobronchial and adjacent lung parenchyma adenocarcinoma were documented. Epithelial markers normalized as she manifested a partial response (PR) lasting 3 years with tamoxifen treatment. From 2001 to 2007 she benefitted from exemestane treatment. Upon progression in the previous lung area and left adrenal, exemestane withdrawal led to transient decrease in markers. Six months later (in July 2008), with growth in her adrenal tumor, laparoscopic adrenalectomy was performed: in addition to ER positivity, the tumor showed Her2 overexpression and amplification. She has subsequently had some control of disease with fulvestrant, letrozole + trastuzumab, and subsequently letrozole + lapatinib. In addition to the chronicity of disease, this history illustrates the expanding range of treatments available for endocrine-responsive breast cancer commensurate to our greater understanding of tumor biology.

We describe a patient with breast cancer who relapsed with an extensive pulmonary lymphovascular tumor embolism. A 38-year-old female, who previously received neoadjuvant chemotherapy and curative resection of breast cancer, underwent adjuvant chemotherapy and was referred to the emergency room because of sudden-onset pleuritic chest pain lasting for 10 days. Despite a trial of empirical antibiotics, the chest pain and the extent of consolidative lung lesion on chest radiographs rapidly aggravated. We performed an open lung biopsy to confirm the etiology. The histopathological review revealed a hemorrhagic infarction caused by lymphovascular tumor emboli from a metastatic breast carcinoma. Palliative first-line chemotherapy was administered, consisting of ixabepilone and capecitabine, and the lung lesion improved markedly.

Solitary fibrous tumor of the pleura (SFTP) is a rare tumor of mesenchymal origin which can grow to a large size and present with symptoms of cough and pleuritic chest pain. No specific etiological factors for SFTPs are known and they may grow undetected for several years. These tumors are usually benign and may mimic a variety of malignancies. SFTPs are often detected as peripheral opacities on chest X-ray. Unfortunately, fine needle aspiration rarely provides adequate information for a definitive diagnosis. Imaging with computed tomography provides details about the size and extent of any invasion into adjacent tissues. Surgical resection is the mainstay of treatment, and immunohistochemistry of the resected tumor often provides confirmation of the diagnosis. Some SFTPs have been observed to be malignant, and surgical intervention is often lifesaving. There is no adequate data to support the usage of radiotherapy and chemotherapy in the treatment of SFTPs. This tumor exemplifies malignancies which require surgical resection to preempt worse outcomes. Awareness of their presentation and clinical course may help the clinician provide a prompt referral to the thoracic surgeon for resection.

Ectopic breast is defined as the presence of breast tissue outside the pectoral region. In this article, we are reporting an extremely rare case of pulmonary aberrant breast tissue. A 79-years-old Caucasian woman with the history of hypertension, diabetes mellitus and ischemic heart disease, presented to the emergency department for worsening dyspnea on exertion and pleuritic chest pain over the last few days. Both thoracic CT scan and the gross evaluation of tumor after its removal by thoracotomy were in favor of a soft tissue tumor such as pulmonary lipoma, whilst surprisingly the histological examinations revealed the mass to be ectopic breast tissue. Although it is extremely rare, this diagnosis should be considered in the evaluation of pulmonary masses.
