Hepatic solitary fibrous tumor: Report of a rare case
Indian Journal of Pathology and Microbiology, 2012
Solitary fi brous tumor (SFT) of the liver is an extremely rare neoplasm of mesenchymal origin. In the English literature, less than 40 cases of SFTs of the liver have been reported. The present case concerns a 34-year-old female who presented to us with complaint of dyspepsia. On examination, there was hepatomegaly. On ultrasound examination, an SOL in the liver was detected. Large tumor measuring 14.5 × 10 × 8 cm was resected. Microscopic evaluation of the tumor showed a well-circumscribed, low to moderately cellular tumor demonstrating spindle-and fi broblast-like cells within the collagenous stroma. Immunohistochemistry revealed diffuse strong cytoplasmic immunopositivity of CD34, Bcl2, and vimentin. A diagnosis of a benign SFT was given. The patient remained well 4 years after surgery. SFT is a rare mesenchymal neoplasm that occasionally involves the liver in adult patients. Most SFTs are benign, but some may have malignant histological features. With less than 40 reported cases in the literature, little can be said regarding its natural history or the benefi ts of adjuvant radio chemotherapy. Complete surgical resection remains the cornerstone of its treatment.
Solitary fibrous tumor of the liver - An unusual entity: A case report and review of literature
Annals of hepato-biliary-pancreatic surgery, 2018
Solitary fibrous tumor (SFT) of the liver is a rare entity and its presentation is usually delayed till they grow to a substantial size. Clinico-radiological features are non-specific, contributing to increase in the diagnostic dilemma. Definitive diagnosis of SFT is usually made based on the histological features and immunohistochemistry data of the resected specimen. In this case report, we describe the case of an elderly male who presented with a large mass in the left lobe of the liver with normal level of tumor markers and atypical radiological findings. The patient successfully underwent resection of the tumor and the diagnosis was confirmed on histopathology.
Solitary fibrous tumor of the liver from development to resection
Internal medicine (Tokyo, Japan), 2015
A 55-year-old man was annually followed up for a large hepatic cyst. In 2006, a 20-mm nodule was detected in contact with the cyst that gradually grew thereafter. By 2013, the mass had expanded to 90 mm, and a percutaneous biopsy revealed a solitary fibrous tumor (SFT). Surgical resection was subsequently performed, and the patient has since been doing well for 11 months, without recurrence. SFT of the liver is a rare neoplasm; only 44 cases have been reported to date. This is the first report to describe the long-term progression of hepatic SFT from the time of its development.
A Giant Solitary Fibrous Tumor of the Liver with Metastasis and Local Recurrence
Journal of Pharmaceutical Research International, 2020
Solitary fibrous tumor (SFT) is a rare type of mesenchymal neoplasm. Although the majority of SFTs are benign, some cases have shown characteristics of malignant neoplasms. Weight loss, fatigue, and upper abdominal bloating are the main signs of these lesions. Clinical and radiographic features are not sufficient for the diagnosis of hepatic SFT and the definitive diagnosis depends on histopathological sampling and immunohistochemistry. One of the main issues in the diagnosis of this tumour is the ability of this tumour to grow to large sizes. A 69-year-old male presented to the clinic 2 years earlier with episodes of hypoglycemia and loss of consciousness. The symptoms improved after receiving glucose. The patient diagnosed as rare solitary fibrous tumour of the liver, a giant (10 × 10 cm in diameter) round and well-defined lesion in the left lobe of the liver which was obvious in magnetic resonance imaging (MRI). Surgery is the most common line of treatment for this disease and there is no evidence regarding the effectiveness of other approaches. According
Solitary fibrous liver tumor: is surgical approach the best option?
Journal of gastrointestinal and liver diseases : JGLD, 2010
Solitary fibrous tumor of the liver is a rare tumor, where the evolution, malignant potential, and invasive growth have not been well defined. Although most cases are benign, there is no strict correlation between histological findings and biological behavior, and follow-up surveillance is necessary. We present the case of a large solitary hepatic fibrous tumor and its clinical outcome after a 4-year follow-up. Additional therapeutic options are also reviewed. The surgical resection is a plausible therapy in large solitary fibrous tumors of the liver, although liver transplantation may be discussed when the tumor is considered unresectable. However, such aggressive approaches are questionable in asymptomatic patients due to the natural history of this tumor, which is not well known, and the risk of complications.

Solitary fibrous tumors (SFTs) are mesenchymal tumors that mostly occur in the pleural cavity. Extra-thoracic location is rare and hepatic origin is extremely rare. Most lesions are benign, 10%-15% show aggressive behavior and few metastasizing SFTs have been reported. Imaging features of solitary fibrous tumors of the liver (SFTLs) are nonspecific and definite diagnosis usually needs histopathological and immunohistochemistry evaluation. We report ultrasound, CT and MRI features of such a rare malignant SFTL in a 47-year-old man who came with vague abdominal symptoms in detail along with reviewing literature considering imaging features which is valuable for radiologists. The lesion seen as a huge dominantly cystic lesion on ultrasound was initially misinterpreted as hydatid. On CT scan it was seen as a large encapsulated mass with arterial hyper-enhancement and delayed contrast retention and multiple cystic spaces. On MRI, solid components showed iso-intensity to adjacent liver on T1 and T2 images, small areas of restriction on diffusion weighted imaging (DWI) and few hemorrhagic cystic components beside enhancement pattern and multiple large cystic components similar to CT scan. Our patient was admitted for resection of huge hepatic mass and experienced an episode of altered mental status due to hypoglycemia during hospital admission, which is a rare finding in SFTL. The patient underwent right hepatectomy and solitary fibrous tumor was confirmed on pathologic examination of the resected tumor. Hypoglycemic episodes were resolved and the patient was asymptomatic in 28 months follow-up.
Giant solitary fibrous tumour of the liver
World journal of surgical oncology, 2006
Solitary fibrous tumour (SFT) is an uncommon mesenchymal neoplasm that most frequently affects the pleura, although it has been reported with increasing frequency in various other sites such as in the peritoneum, pericardium and in non-serosal sites such as lung parenchyma, upper respiratory tract, orbit, thyroid, parotid gland, or thymus. Liver parenchyma is rarely affected. Clinically, SFTs cause symptoms after having reached a certain size or when vital structures are involved. In recent years, SFTs are more often identified and distinguished from other tumours with a similar appearance due to the availability of characteristic immunohistochemical markers. In this manuscript we report the case of a large tumour of the liver, which was histologically diagnosed as a SFT, and showed involvement of a single hepatic segment. Because of the patient's presentation and clinical course, it may represent a radiation-induced lesion. When a SFT has been diagnosed, surgery is the treatmen...

Background: Solitary fibrous tumor (SFT) is a rare fibroblastic mesenchymal tumor. It can originate from abdominal soft tissue which is extremely scarce, and liver indeed is super scant site. SFT liver (SFTL) is mostly benign, but it can be malignant and aggressive with metastases and a potential of recurrence. Hypoglycemia is the least reported feature which is resistant to medical management and will be resolved following resection of a SFT of liver. Case Report: A 67-year-old man presented with episodes of sudden onset loss of consciousness since 3 months before first visit. He was a previously healthy farmer, without any other complaint or past medical history except for episodes of sever hypoglycemia. Laboratory testing revealed hypoglycemia which was temporarily response to glucose infusion, hypoglycemia was refractive, and whole physical examination and laboratory tests were done and there were no abnormal findings. With probability of finding something such as insulinoma or ...
Malignant metastasizing solitary fibrous tumors of the liver: a report of three cases
Polish Journal of Pathology, 2015
Solitary fibrous tumors are rare neoplasms of mesenchymal origin that have been reported in various other extrathoracic sites, including the liver. We present a case series of three malignant solitary fibrous tumors of the liver, occurring in two women 74 and 80 years old and one 65-year-old man. No clinical features were predictive of malignancy except the large sizes and synchronous presence of lung metastases in two of the three cases. Histological examinations revealed the presence of high pleomorphic cellularity with nuclear atypia, necrosis and high mitotic ratios. All patients died of disease progression.
