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.

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.

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 A 53-year-old Caucasian male presented with a 2-week history of abdominal distension, pain, nausea and lethargy. His symptoms began 1 day after an all-terrain vehicle accident during which he suffered blunt-force trauma to his mid-right abdomen. CT scan demonstrated abnormal thickening of the ascending colon and terminal ilium with surrounding inflammation within the retroperitoneum and colonic mesentery. Given his likely mechanism and symptomatic improvement, he was initially managed conservatively. However, he was readmitted with recurrence of symptoms, and a repeat CT scan demonstrated no interval improvement. An exploratory laparotomy was performed and a firm, fixed mass of the right-colon and colonic mesentery was found. Final histopathology of the mass revealed a diffuse lymphoid infiltrate with numerous mitotic figures and apoptotic cells. Immunohistochemical staining was positive for CD45, CD20, CD10, and BCL-6 and negative for CD3, TdT, and BCL-2, indicating a diagnosis of Burkitt lymphoma.

Abstract Background Solitary fibrous tumor (SFT) is a rare mesenchymal tumor that typically arises from the pleura. Although it may appear in other organs, it rarely develops in the pancreas. We report herein a rare case of metastatic SFT of the pancreas originating from an intracranial tumor and subsequently identified as a cystic neoplasm of the pancreas. Case presentation A 58-year-old woman with a past medical history of brain tumor visited the hospital for further investigation of a cystic tumor in the pancreas tail. Abdominal imaging showed a heterogeneously enhancing mass that was initially suspected as a neuroendocrine neoplasm, solid pseudopapillary neoplasm, or mucinous cystic neoplasm of the pancreas. Distal pancreatectomy was performed without any intraoperative and postoperative complications. Pathological findings confirmed a diagnosis of malignant SFT of the pancreas with hyperproliferative potential. A histopathological review of her brain tumor revealed that the pancreatic tumor was derived from her brain lesion. The patient developed recurrent brain disease 4 years after the pancreatectomy, but no recurrence has been observed in the abdominal cavity. Conclusions SFT should be considered in the differential diagnosis of untypical hypervascular pancreatic mass, particularly in patients with a history of an intrathoracic or intracranial mesenchymal tumor. Immunohistochemical analysis is crucial in detecting this tumor entity. Hyperproliferative status indicates a malignant disease and requires careful postoperative observation.

Introduction: There is very limited published experience with intravenous (IV) antituberculosis (anti-TB) and antiretroviral therapy (ART) especially in children. We have described a human immunodeficiency virus (HIV)-infected child with complicated abdominal tuberculosis who was initially treated with IV anti-TB and a partially IV ART regimen before transitioning to oral therapy.Patient presentation: A 3-year-old boy presented with hypovolaemic shock with a 3-day history of inability to pass stools, abdominal distension and bile-stained vomiting. Abdominal ultrasound and X-ray showed small-bowel obstruction. Human immunodeficiency virus antibody testing was positive, and Cluster of Differentiation (CD)4+ lymphocyte count was 56 cells/mL (15%). Xpert Mycobacterium tuberculosis (MTB)/Rifampicin (RIF) Ultra and TB culture on induced sputum detected MTB complex sensitive to rifampicin and isoniazid.Management and outcome: Following laparotomy and closure of bowel perforations, the child was commenced on IV rifampicin, moxifloxacin and amikacin. Amikacin was stopped after 3 days because of nephrotoxicity, and meropenem and IV linezolid were added. After 20 days, ART comprising IV zidovudine, oral lamivudine solution, oral lopinavir/ritonavir solution and additional oral ritonavir solution for super boosting was commenced. By day 40, the patient was well established on oral feeds and was switched to standard oral anti-TB medications. Sputum examined 1 month after starting the treatment was found culture-negative for MTB. After 4 months of treatment, the HIV viral load was 100 copies/mL. He completed a total of 12 months of anti-TB treatment.Conclusion: Despite limited experience and few available IV formulations of standard anti-TB and ARV medications, initial IV therapy may be beneficial for patients in whom oral medication is not an option.

Solitary fibrous tumors (SFTs) are rare mesenchymal tumors, originally identified in the pleura. Even though they have subsequently been described in several extrapleural sites, the incidence of SFTs in the spermatic cord is particularly rare. Here, we report a case of a 27-year-old male that presented with a 3-year history of left scrotal swelling. Computed tomography (CT) and ultrasound demonstrated multiple solid, hypoechoic well-circumscribed masses that were separate from the testis. Surgical excision of the mass led to pathologic diagnosis of a solitary fibrous tumor involving the spermatic cord. Solitary fibrous tumors, although rare, are an important differential diagnosis for urogenital tumors.

ABSTRACT A 4 mo old intact male Labrador retriever was referred to the authors’ institution for a 3 wk history of weight loss and progressive abdominal distension. Thoracic radiographs revealed sternal lymphadenopathy and a diffuse unstructured interstitial and bronchial pulmonary pattern. An abdominal ultrasound revealed multifocal lymphadenopathy, hepatosplenomegaly, and biliary duct dilation. Fine-needle aspirates of the spleen and liver revealed Histoplasma capsulatum organisms. Antifungal therapy was initiated with itraconazole and terbinafine. Repeat ultrasound examinations revealed resolving hepatosplenomegaly and resolving cystic duct dilation. Ultrasonographic findings mirrored a decrease in urine H capsulatum antigen levels. Histoplasmosis should be considered as a differential for unexplained biliary duct dilation or obstruction in dogs. Dogs with disseminated histoplasmosis should be monitored for this potential complication.

Abstract Pancreas is an extremely rare abdominal localization of the solitary fibrous tumor (SFT). It usually grows asymptomatically for a long time before a diagnosis can be made on the basis of symptoms and/or mechanical complications. Due to the rarity and nonspecific clinical presentation, this entity is diagnostically challenging. We present a 47-year-old man with a history of progressive epigastric pain for the last two weeks, and jaundice, who was admitted to hospital for further investigation. Cystadenocarcinoma was suspected based on the radiologic findings, and a pancreatoduodenectomy was performed. The removed portion of the pancreas contained a 3.5 × 2 × 1.8 cm well-circumscribed, but not encapsulated white tumor mass with smooth cut surface, cystic component and duct dilatation within the tumor and within the adjacent pancreatic tissue. Based on the histology and immunostaining profile, a diagnosis of the solitary fibrous tumor was made. One week post-operatively, the patient died due to surgical complications. Microscopic and immunohistochemical examinations are necessary for accurate diagnosis of cystic SFT of the pancreas. Because there is limited data regarding the biological behavior of SFT with extra-pleural localization the authors recommend clinical follow-up for SFT treatment if the criteria of malignancy are not met.
