Solitary fibrous tumors of the pleura: a case report and review of the literature.

Abstract

BACKGROUND:

Solitary fibrous tumors of the pleura are rare and slow-growing neoplasms originating from the mesenchymal tissue underlying the mesothelial layer of the pleura. These tumors may have an unpredictable clinical course. Most cases occur in the sixth or seventh decades of life with no gender predilection, and more than 80% of cases are benign. The predominant clinical symptoms and signs are dyspnea, cough, chest pain, finger clubbing and hypoglycemia. However, because many patients are asymptomatic, the incidence rates are affected by the likelihood of its incidental detection, often through medical imaging of the chest. Surgical resection is the treatment of choice and is usually curative, even though local recurrence can occur many years after an adequate resection.

METHODS:

We reviewed the literature by performing a computerized search of MEDLINE, CANCERLIT and Embase with the terms fibrous tumor, pleura, surgery, immunohistochemical analysis. Articles and s were also identified by back-referencing from other relevant papers.

RESULTS:

The clinical, radiological and pathological features of a 48-year-old woman with a primary solitary fibrous tumor of the pleura are reviewed and a literature search for other reported cases has been performed.

CONCLUSIONS:

Although localized fibrous tumors of the pleura are considered histologically benign, there is a risk of recurrence and malignant transformation. Complete surgical resection is mandatory and long-term clinical and radiological follow-up is indicated in all patients. For malignant cases complete surgical resection may not be adequate and studies are needed to define the role of preoperative and postoperative systemic treatment. Diagnosis is very difficult in limited samples such as fine-needle aspiration or needle-core tissue biopsy, and immunohistochemical analysis may be useful to differentiate solitary fibrous tumor of the pleura from mesothelioma and other similar tumors.
