Solitary fibrous tumor (SFT) is one of the mesenchymal tumors, which rarely arises in the abdominal space. We report a very rare case of abdominal SFT, mimicking another mesenchymal tumor. A 52-year-old Japanese man was referred to our hospital for further evaluation and treatment of gallbladder polyp. Contrast-enhanced computed tomography (CT) showed an enhanced nodule within the gallbladder, and incidentally, also showed a well-circumscribed mass adjacent to the small intestine. The mass was depicted as slightly high density in plain CT, and with contrast-enhancement, the mass was partially stained in early phase and the stained area spread heterogeneously in delayed phase. Magnetic resonance imaging showed that the abdominal mass was depicted as slightly high intensity on T2-weighted imaging and low intensity on T1-weighted imaging. With double-balloon endoscopy and capsule endoscopy, we did not find any tumor inside the small intestine. These visual findings lead us to diagnose it as gastrointestinal stromal tumor of the small intestine with extraluminal growth. We planned to resect both the gallbladder polyp and the intraperitoneal tumor at the same time for pathologic diagnosis and treatment. When the operation was performed, we found a milk-white lobulated tumor on the greater omentum and the tumor was entirely resected. Microscopically, the gallbladder polyp was diagnosed as tubular adenoma, and the omental tumor was diagnosed as SFT. It is important to bear in mind that omental SFTs sometimes mimic other mesenchymal tumors and should be included in the differential diagnosis of abdominal tumor not revealed by endoscopy.

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.

Fibrous Tumor

A 60-year old man presented with a one week history of intermittent periumbilical pain. He had weight loss of half a stone over 6 weeks and abdominal distension for 2 weeks, there was no other systemic complaint. General examination revealed bilateral Dupuytren`s contracture and grade 4 finger clubbing. Abdominal palpation revealed a very large non tender mass. The Liver and spleen were difficult to assess because of the size of the mass. Rectal examination was normal. An abdominal Ultrasound showed a central abdominal mass of mixed echogenicity. CT scan showed a large lobulated mass with overlying serpinginous vessels with a clear plane posteriorly separating it from the retro-peritoneum. Liver, spleen and pancreas showed no abnormality. CT scan of the chest showed no abnormality. Core biopsy under ultrasound guidance revealed features consistent with a solitary fibrous tumor, haemangiopericytoma or angiosarcoma. The patient underwent a midline laparotomy. The huge mass was attached to the greater omentum by a pedicle with minimal adhesions to the lateral peritoneum. It was excised compeletly. The post-operative course was uneventful. Gross pathological findings macroscopically revealed the mass measuring 24x19x10 cm, weighing 3870 grams and on section it was a fleshy lobulated tumour with a few cystic areas. There was some attenuated fat on part of the surface. Histologically, the architecture was pattern-less with prominent stromal hyalinization, varying cellularity (mainly spindle and ovoid cells) and branching (haemangiopericytoma-like) vessels.

Gastric schwannomas are rare mesenchymal tumors that arise from the nerve plexus of gut wall. They present with nonspecific symptoms and are often detected incidentally. Preoperative investigation is not pathognomic and many are therefore misdiagnosed as gastrointestinal stromal tumors. We report a rare case of a 37-year old woman who underwent laparotomy for complex bilateral ovarian cyst with resection of gastric-gastrointestinal stromal tumor preoperatively, but confirmed to have a gastric schwannomas postoperatively. This case underscores the differential diagnosis of submucosal, exophytic gastric mass as schwannoma.

Desmoid tumors (deep fibromatosis) of the mesentery are rare mesenchymal tumors. They are often misdiagnosed, especially with a previous history of resection for gastrointestinal stromal tumor (GIST). Immunohistochemistry can help differentiate between these two tumors. In this article, we present a case we had encountered: a Desmoid tumor developing in a patient with a history of GIST 3 years ago. It is the first case of GIST with subsequent development of Desmoid tumor to be reported in Saudi Arabia. We discuss the two entities of Desmoid tumor and GIST by comparing their definitions, clinical presentations, histological features, immunohistochemistry stains, molecular pathogenesis, prognosis, and treatment. We also discuss the relationship between GIST and the subsequent development of Desmoid tumors and compare our case with case reports in literature.

Gastrointestinal stromal tumors are rare tumors, originating from the interstitial cells of Cajal. They are the most common mesenchymal tumors of the gastrointestinal tract. Metastatic tumor is treated with imatinib mesylate. A case of large metastases of a gastrointestinal stromal tumor to the omentum, diagnosis and treatment principles are presented in this case report.
