Pancoast syndrome caused by a high grade B cell lymphoma

Pancoast Tumor as the Initial Presentation of a Metastatic Colon Adenocarcinoma

A Pancoast tumor is a rare condition, representing 3% to 5% of all lung cancers. The particular location of these lesions leads to the invasion of structures in the thoracic inlet, causing a constellation of symptoms known as Pancoast-Tobias syndrome. Diagnosis can be challenging due to their low prevalence and the possibility of being asymptomatic. Most of these tumors are non-small cell lung cancers. However, rare conditions might arise at the same location, and histologic confirmation is relevant. We report the case of a 45-year-old man admitted to the internal medicine department with a one-month history of night sweats. A full-body computed tomography (CT) scan revealed a mass on the upper lobe of the left lung, with soft tissue invasion. Histopathologic examination revealed an adenocarcinoma pattern originating from the colon. Colonoscopy showed two synchronous lesions. Hitherto, this is the second case ever described of a Pancoast tumor as metastasis of colon adenocarcinoma.

Horner's Syndrome as Initial Manifestation of Possible Brachial Plexopathy Neurolymphomatosis

Introduction: Horner's syndrome is an established clinical finding unique to neoplastic brachial plexopathy.

Background: We present the case of a patient who developed Horner's syndrome as the first manifestation of neurolymphomatosis (NL) of the brachial plexus that did not have the usually associated bulky adenopathy/Pancoast syndrome phenotype.

Discussion: We discuss the clinical utility of Horner's syndrome with regards to brachial plexopathy of indeterminate etiology, as well as the utility of other diagnostic modalities in NL.

Concluding Remarks: NL, particularly of the brachial plexus, is particularly challenging to diagnose. MRI and CSF studies are often inconclusive. FDG-PET imaging can be difficult to get insurance to approve. The presence of Horner's syndrome in brachial plexopathy of indeterminate etiology, even in the absence of bulky adenopathy, should raise clinical suspicion of NL, possibly prompting such interventions as fascicular nerve biopsy.

Recurrent Diffuse Large B-Cell Lymphoma Presenting with Pancoast Syndrome: A Rare Cause of Radicular Neck Pain in the Emergency Department

BACKGROUND

Pancoast syndrome is an uncommon complication of apical lung tumors. Symptoms include pain, brachial plexopathy, and Horner's syndrome, and are the result of extrinsic compression of tissues within the thoracic inlet. Lymphoma is a very rare etiology.

CASE REPORT

We describe the presentation of a 59-year-old male with recurrent diffuse large B-cell lymphoma presenting with Pancoast syndrome. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Cancer is an uncommon cause of radicular neck pain but should be considered in the differential, particularly when constitutional complaints are also present. Symptoms and physical examination findings associated with Pancoast syndrome are the consequence of compression of the C7-T2 vertebral roots and sympathetic chain. Computed tomography is usually required to definitively visualize the mass.

A Case of Pancoast Tumor with Unusual Presentation

INTRODUCTION

 The Pancoast syndrome (PS) has been termed after Henry Pancoast. Its neurologic core symptoms include pain, radicular sensory and motor syndromes, and Horner syndrome. A PS is often the presenting sign of lung cancer and bears a grim prognosis.

METHODS

 This case report describes an atypical onset of a lung tumor causing a PS. Electrophysiological examination was not conclusive. The diagnosis was confirmed by MRI, CT scan, and biopsy. The intervention consisted of preoperative chemo- and radiotherapy and was followed by an extensive surgical approach with histologically confirmed perineural invasion of the brachial plexus.

RESULTS

 The postoperative period was dominated by neuropathic pain. Despite considerable loss of distal sensorimotor function of the right hand, the patient uses the extremity and has returned to professional life.

DISCUSSION

 This observation triggered by the advances in general oncology and surgery also demonstrates the management of a lesion of the peripheral nervous system caused by cancer.

Horner syndrome: clinical perspectives

Horner syndrome consists of unilateral ptosis, an ipsilateral miotic but normally reactive pupil, and in some cases, ipsilateral facial anhidrosis, all resulting from damage to the ipsilateral oculosympathetic pathway. Herein, we review the clinical signs and symptoms that can aid in the diagnosis and localization of a Horner syndrome as well as the causes of the condition. We emphasize that pharmacologic testing can confirm its presence and direct further testing and management.

Pancoast tumors: characteristics and preoperative assessment

Superior sulcus tumors (SSTs), or as otherwise known Pancoast tumors, make up a clinically unique and challenging subset of non-small cell carcinoma of the lung (NSCLC). Although the outcome of patients with this disease has traditionally been poor, recent developments have contributed to a significant improvement in prognosis of SST patients. The combination of severe and unrelenting shoulder and arm pain along the distribution of the eighth cervical and first and second thoracic nerve trunks, Horner's syndrome (ptosis, miosis, and anhidrosis) and atrophy of the intrinsic hand muscles comprises a clinical entity named as "Pancoast-Tobias syndrome". Apart NSCLC, other lesions may, although less frequently, result in Pancoast syndrome. In the current review we will present the main characteristics of the disease and focus on the preoperative assessment.

Pancoast's syndrome secondary to lung infection with cutaneous fistulisation caused by Staphylococcus aureus

Apical bronchial carcinoma is the most common cause of Pancoast's syndrome. Of the many other causes reported, infection is a rare one. A literature review is presented and a case of Pancoast's syndrome, secondary to apical lung pneumonia with bronchocutaneous fistulisation caused by Staphylococcus aureus infection, is reported. Clinical and radiological resolution was achieved after treatment with antibiotics.

Pancoast's syndrome in a patient with B-cell lymphoma diagnosed and confirmed with immunoglobulin gene rearrangement

Pancoast's syndrome due to malignant lymphoma is extremely rare. A case of diffuse large B-cell lymphoma presenting as Pancoast's syndrome is described. A 66-year-old man complained of pain and weakness of the right arm, and CXR revealed a right apical lung tumour. Histological findings were consistent with it being a diffuse large cell type lymphoma and Southern blot analysis revealed clonal rearrangement of the immunoglobulin heavy-chain JH. Thus, the tumour in this patient was diagnosed to be diffuse large B-cell lymphoma. Malignant lymphoma is an extremely rare cause of Pancoast's syndrome and only five cases have been described. This is the first reported case of Pancoast's syndrome caused by B-cell lymphoma, which was accurately diagnosed by analysis of gene rearrangement.

[Pancoast-Tobias syndrome disclosing a primary pulmonary non-Hodgkin lymphoma]

INTRODUCTION

Pancoast's syndrome is generally due to superior sulcus tumors, generally bronchial cancer. In rare cases, other causes are found, but these are potentially curable.

CASE-REPORT

A 78-year old woman with a long history of tobacco intake presented with Pancoast's syndrome in the form of a locally invasive left apical lung mass. Despite her advanced age and the diagnosis of the high probability of lung cancer, a transparietal biopsy procedure was nevertheless performed, with the subsequent diagnosis of primary malignant pulmonary lymphoma. The patient was satisfactorily treated by combined chemotherapy.

CONCLUSION

The present study has shown that malignant non-Hodgkin lymphomas should be considered in the etiology of the disease, and as a rare but potentially treatable cause of Pancoast's syndrome.

[Pancoast's syndrome secondary to neck metastasis with normal radiography of the thorax]

Pancoast's syndrome is characterized by pain in the shoulders and upper extremities, Horner's syndrome, bone loss and hand muscle atrophy. Bronchogenic carcinoma is the most common cause, although other neoplasms or lung infection are occasionally responsible. An apical mass on the chest film can be seen in over 90% of cases, although apical pleural thickening is sometimes the only radiographic finding. We describe a patient whose clinical picture was highly suggestive of Pancoast's syndrome but whose chest film was normal. Magnetic resonance imaging disclosed a cervical mass adjacent to the brachial plexus that proved to be cervical metastasis from an unknown primary tumor. We emphasize the need to consider the possibility of a metastatic cervical tumor compromising the brachial plexus in patients with a normal chest X-ray but clinical signs highly suggestive of Pancoast's syndrome.

Non-Hodgkin's lymphoma presenting as Pancoast's syndrome

Pancoast's syndrome is generally caused by primary or metastatic epithelial tumors. Other causes of the syndrome are unusual but well described. The present case report describes a rare case of Pancoast's syndrome caused by non-Hodgkin's lymphoma. This report emphasises the importance of establishing a firm pathologic diagnosis of the etiology of Pancoast's syndrome before instituting treatment.

Pancoast (superior sulcus) tumors

Primary carcinomas arising in the apex of the lung (Pancoast tumors) have attracted attention because of the characteristic syndrome that is produced by local extension into the chest wall and the brachial plexus. This article reviews the history of the treatment of this disease, the natural history of untreated patients, and the diagnosis of Pancoast tumors. The published data on results, prognostic factors, and technical aspects of treatment with combined irradiation and operation are examined, as well as those pertaining to treatment with irradiation alone.
