Solitary Fibrous Tumor of the Great Omentum: A Case Report and Literature Review

Background: We report a case of a 23-year-old man with a solitary fibrous tumor of the great omentum who presented clinically as a case of dull abdominal pain. Case Presentation: Solitary fibrous tumor normally occurs in the visceral pleura. Extrathoracic solitary fibrous tumor is rare, especially those from the great omentum, with approximately 31 cases reported in the literature. Conclusion: After reviewing and summarizing the imaging findings of 31 cases of solitary fibrous tumor of the greater omentum, we considered that the characteristic findings can provide a reliable basis for preoperative diagnosis.

Abstract Background Solitary fibrous tumor (SFT) is a rare neoplasm of mesenchymal origin occurring most often in the visceral pleura, however, it has been described in almost every anatomic location of the human body. While most SFTs have a benign behavior, they can potentially be locally aggressive and demonstrate a malignant behavior. Case presentation A 63 year-old male patient presented with lower abdominal pain and nausea and was noted on CT to have a large, heterogeneous lower abdominal mass with no evidence of metastatic disease. A surgical resection was performed and the mass appeared to be connected to the greater omentum with a vascular pedicle. It was not invading any intra-abdominal or pelvic organs. Pathology revealed an SFT of omental origin. The mitotic count was less than 4 per 10 high-power fields and all pathologic characteristics did not meet the criteria for a malignant SFT. Conclusions We report an extremely rare case of SFT originating from the greater omentum. A multidisciplinary team approach was followed to plan the patient’s management strategy.

ABSTRACT Localized fibrous tumors of the lung arise from the visceral pleura and are pedunculated. They also project into the pleural cavity. The tumor with an entirely pulmonary location is extremely rare. We present here a rare case of intrapulmonary localized fibrous tumor with review of the literature.

Solitary fibrous tumor is an unusual spindle cell neoplasm that usually occurs in the pleura but has also been described in other sites. Renal presentation is rare and only 38 cases of SFT of the kidney have been described until now. Up to 90% of the tumors have benign characteristics. Local retroperitoneal recurrence is extremely rare. We report a case of a large malignant solitary fibrous tumor recurrence after the surgical excision of the primary tumor. Histological examination of the specimen confirmed the diagnosis by revealing highly positive reaction of the neoplasmatic cells for vimentin, CD34, bcl-2 and moderately positive for actin. The rate of Ki67 lied between 2–7%. No adjuvant therapy was given to the patient and he is disease-free with no imaging findings of recurrence or metastasis 9 months after the re-operation.

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.

Contrast Enhanced

Introduction: Cholangiolocellular carcinoma (CoCC) is a rare primary liver neoplasm. A recent integrative genomic analysis has revealed that CoCC represents a distinct biliary-derived molecular entity. Several cases of CoCC have been reported so far, but accurate preoperative diagnosis was difficult in most cases. Case presentation: We report a case of 70-year-old woman with CoCC. Preoperative imaging findings revealed several typical signs of CoCC (i.e., thick early ring enhancement in the peripheral area of the tumor and its prolongation, vessel penetration through the tumor, no dilatation of the peripheral bile ducts, and dot-/band-like internal enhancement or a target appearance on contrast-enhanced magnetic resonance imaging). We strongly suspected CoCC from these preoperative imaging findings of the tumor and performed extended left hepatectomy. Pathologic diagnosis was CoCC, and the histologic findings such as peripheral highly cellular areas, central abundant hyalinized/edematous fibrotic stroma, and retained Glisson's sheath structures in the tumor, corresponded closely to each preoperative imaging finding. Immunohistochemical study revealed the tumor cells were positive for cytokeratin 7 and epithelial membrane antigen. The postoperative course was uneventful, and the patient is alive without recurrence for 15 months. The prognosis of CoCC is known to be better than that of cholangiocellular carcinoma, indicating the importance of preoperative differential diagnosis of these tumors. Conclusion: Even though preoperative diagnosis of CoCC is difficult because of its rarity, cautious investigation of preoperative typical imaging findings can possibly lead to accurate diagnosis of CoCC.
