Acute Retention

The solitary fibrous tumor is an infrequent neoplasm of mesenchymal origin, mainly pleural, exceptionally urogenital. Our patient is 71 years old with no specific history who was presented to the emergency room for acute retention of urine relieved by a bladder catheter. An Uroscanner showed a thickening of the bladder wall which prompted the medical staff to perform a RTUV whose histological and immunohistochemical study confirmed the diagnosis of a solitary fibrous tumor of the bladder. Solitary fibrous tumors remain slow-growing neoplasms regardless of their site. The prognosis and aggressiveness are difficult to specify. Recurrences, locoregional extension and distant metastases can be seen in 10 to 20% of cases.

Abstract Solitary fibrous tumors are relatively rare mesenchymal neoplasms that were originally described as pleural- or peritoneal-based lesions. Although they were considered a form of mesothelioma, subsequent investigation failed to reveal mesothelial differentiation. Characterization of their histologic and immunohistochemical features, as well as identification in a multitude of nonmesothelial-based locations has further served to distinguish these lesions from the more diffuse and aggressive mesothelioma. Reports of solitary fibrous tumor in the larynx are extremely rare. We report a case of solitary fibrous tumor of the larynx in a 38-year-old man.

Fibrous Tumor

Solitary fibrous tumors are uncommon spindle cell neoplasms generally associated with serosal surfaces, especially the pleura. Recently, these tumors have been documented in a number of extrapleural sites including the head and neck. So far only two cases of parapharyngeal solitary fibrous tumor have been reported in the English literature. Rare location of an uncommon lesion often gives rise to difficulty in diagnosis or to misdiagnosis. In both the previously reported cases, as well as in our case, the diagnosis of solitary fibrous tumor was not made until the excised tumor was subjected to histopathology and immunohistochemistry.

Malignant Behavior

Solitary fibrous tumors are relatively rare neoplasms that commonly occur in the pleura, especially visceral pleura. However, an intrapulmonary site of this kind of tumors is even rarer. These tumors can be characterized by a heterogeneous evolution and have a benign or malignant behavior. Wide surgical resection is essential to cure the patient and to avoid recurrence. We present here the clinical, imaging, and histological features of a case with solitary fibrous tumor growing inside the lung.

Recurrent Hypoglycemia

Introduction: Doege-Potter syndrome is a rare syndrome characterized by hypo-insulinemic hypoglycemia. It is caused by excessive ectopic secretion of insulin-like growth factor II from a solitary fibrous tumors of intrapleural or extrapleural origin. Laboratory tests reveal low levels of C-peptide and insulin, on the contrary insulin-like growth factor II level is elevated, which is characteristic for Doege-Potter syndrome. Majority of solitary fibrous tumors present no symptomatology, recurrent hypoglycemia is relatively rare, but it may be the only clinical manifestation. The therapy is surgical, consisting of radical en-bloc tumor resection. Case report: Authors present a case report of a patient with recurrent hypoglycemia caused solely by solitary fibrous tumor. Hypoglycemia resolved immediately after surgical resection and there were no recurrences. Conclusion: Doege-Potter syndrome should be considered as the differential diagnosis in a patient with suspicion on thoracic malignancy if accompanied by features suggestive of hypoglycemia. Prolonged follow up is strongly advised because of the risk of disease recurrence, even in patients with benign solitary fibrous tumors of the pleura (SFTP).

Introduction. Solitary fibrous tumors are rare soft tissue tumors of submesothelial origin and variable malignant potential. The most common localization is pleural, whereas only 0.6% are of extrapleural localization. Solitary fibrous tumor of the peritoneum, especially of gastric serosa is an extremely rare form of this tumor. Case report. We presented a 65- year-old female patient with solitary fibrous tumor of the stomach. Histopathological analysis of removed tissue showed the presence of tumor tissue built of spindle cells, elongated nuclei with moderately abundant cytoplasm. Cells were in a noncohesive arrangement, in smaller areas distributed in the form of palisade. There were amounts of hipocellular connective tissue, hyalinised, with small foci of dystrophic calcification. Mitoses were rare (less than 3/10 HPF). Blood vessels surrounded the connective tissue. Reviewed material did not contain elements of the parent organ. Immunohistochemically there were positivity on CD34 and vimentin, and negativity to S100, SMA, CD117, dezmin, and Ki-67 is < 2%. The change was diagnosed as a solitary fibrous tumor. Conclusion. Considering that benign solitary fibrous tumors of extrathoracic localizations are extremely rare neoplasms with unpredictable biological behavior and the possibility of recurrence, a long-term clinical and endoscopic follow-up on yearly basis of patients with this disease is recommended.

Introduction: Solitary fibrous tumor is a neoplasm of mesenchymal origin with benign and malignant forms. We aimed to present a case of solitary fibrous tumor which developed in a patient operated for laryngeal cancer and originated from diaphragm in the light of the literature. Case report: A 61-year-old male patient with tracheostomy with an undiagnosed lesion that appears to be almost 10 cm was referred to our clinic. Since it was a large volume mass, we chose to perform a thoracotomy over thorachoscopic approach. Discussion: Although solitary fibrous tumors most commonly occur in the pleura but may also originated from diaphragm, and our case is valuable that originates from diaphragmatic since there are less than 5 reported cases in literature for past two decades. Conclusion: Even in the case of recurrence, the main treatment remains as total surgical excision. Solitary fibrous tumors are usually detected because of compression symptoms. That is the main reason why we chose thoracotomy.

Abstract Background Solitary fibrous tumor (SFT) is a relatively rare mesenchymal tumor that mainly affects adults. Its prognosis is good after curative resection, but distant recurrences after 10 years or longer have been reported. Recurrent SFT usually arises as a local lesion; distant metastasis is rarely reported. Here, we report lung metastases that recurred a decade after excising a retroperitoneal primary SFT. Case presentation A 44-year-old woman had an SFT resected from her right retroperitoneum at our hospital. Ten years later, at age 54, she underwent a lung resection after CT showed three suspected metastases in her left lung. All three were histologically diagnosed as lung metastases from the retroperitoneal SFT. However, whereas the primary SFT had 1–2 mitotic cells/10 high power fields (HPF), the metastatic lesion increased malignancy, at 50/10 HPF. Conclusion Patients who have had resected SFTs should be carefully followed up, as malignancy may change in distant metastasis, as in this case.
