Non-gastrointestinal stromal tumor, mesenchymal neoplasms of the gastrointestinal tract: a review of tumor genetics, pathology, and cross-sectional imaging findings. Abdom Radiol (NY) 2024; 49:1716-1733. [PMID: 38691132 DOI: 10.1007/s00261-024-04329-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2024] [Revised: 04/01/2024] [Accepted: 04/02/2024] [Indexed: 05/03/2024]
Abstract
There is a diverse group of non-gastrointestinal stromal tumor (GIST), mesenchymal neoplasms of the gastrointestinal (GI) tract that demonstrate characteristic pathology and histogenesis as well as variable imaging findings and biological behavior. Recent advancements in tumor genetics have unveiled specific abnormalities associated with certain tumors, influencing their molecular pathogenesis, biology, response to treatment, and prognosis. Notably, giant fibrovascular polyps of the esophagus, identified through MDM2 gene amplifications, are now classified as liposarcomas. Some tumors exhibit distinctive patterns of disease distribution. Glomus tumors and plexiform fibromyxomas exhibit a pronounced affinity for the gastric antrum. In contrast, smooth muscle tumors within the GI tract are predominantly found in the esophagus and colorectum, surpassing the incidence of GISTs in these locations. Surgical resection suffices for symptomatic benign tumors; multimodality treatment may be necessary for frank sarcomas. This article aims to elucidate the cross-sectional imaging findings associated with a wide spectrum of these tumors, providing insights that align with their histopathological features.

Abstract
Since the introduction of new molecular techniques, the diagnostic landscape of soft tissue and bone tumors has expanded greatly over the past few years. The use of new molecular techniques has led to the identification of new genetic alterations and, therefore, to a better understanding of tumorigenesis, tumor detection and classification. Furthermore, methylation profiling has emerged as a classification tool for soft tissue and bone tumors. Molecular pathology also plays an important role in the determination of patient prognosis and in the identification of targets that can be used for targeted therapy. As a result, molecular pathology has gained a more prominent role in the daily practice of the surgical pathologist. This review delves into various molecular techniques applied in the surgical pathology of soft tissue and bone tumors. It highlights their applications through the analysis of five specific cases.

Abstract
BACKGROUND Fibrovascular polyps are rare type of esophageal submucosal neoplasms. They are highly vascularized and can cause difficulty swallowing and even fatal complications such as uncontrolled bleeding and death caused by asphyxiation in case of tumor migration to oropharynx. In the article we describe a novel hybrid technique to surgical treatment – an endoscopic submucosal dissection with laparoscopic removal of the tumor.
CASE SUMMARY The patient with a giant fibrovascular esophageal polyp presented with cough, discomfort in the throat, difficulty swallowing, and an episode of tumor migration into oropharynx. The patient was investigated with several imaging studies and was diagnosed with a giant highly vascularized esophageal fibrovascular polyp. The follow-up period of eight months accompanied with no complications.
CONCLUSION This method has been shown to have comparable rates of recurrence and a low risk of complications.

Abstract
Liposarcomas are extremely rare occurrences in the esophagus. Here, we present an unusual case of esophageal liposarcoma that contributed to a long history of dysphagia before a definitive diagnosis was reached. The case is that of a 61-year-old woman who complained of dysphagia and foreign body sensation in her throat and was found to have a large filling defect within the cervical esophagus on barium esophagogram. She underwent endoscopic resection of the mass and was diagnosed with a five-centimeter long, well-differentiated esophageal liposarcoma, confirmed with fluorescence in situ hybridization for MDM2 gene locus amplification. Subsequent laser ablation of the tumor bed was conducted with no recurrences noted to date. Proper histologic identification, alongside adjunctive cytogenetic and molecular diagnostics, followed by definitive surgical resection and extended follow-up, are emphasized as critical in optimizing outcomes for this disease. A review of the existing English-language medical literature relating to esophageal liposarcoma was performed and summarized.

Abstract
BACKGROUND Liposarcoma is a malignant mesenchymal tumor that most commonly involves the retroperitoneum and lower extremities. However, liposarcoma of esophagus has been rarely reported in the literature. CASE PRESENTATION We report a case of a 46-year-old man with complaint of intermittent dysphagia for 6 years, accompanied with paroxysmal vomiting of pedicled tumor to the mouth. Imaging studies showed a huge mixed density lesion in the middle esophageal lumen. Surgical resection of the tumor was performed through an external cervical approach. Microscopically, the tumor was composed of mature adipocytes in normal adipose tissue prominently intersected by sparsely cellular fibrous septa containing atypical, enlarged spindle cells with hyperchromatic nuclei. Immunohistochemically, the tumor cells were positive for Vimentin, S-100, CD34 and MDM2. Besides, fluorescence in situ hybridization (FISH) analysis indicated the presence of amplification involving MDM2 gene. The patient was diagnosed as having esophageal well-differentiated liposarcoma and recovered well after the operation. CONCLUSIONS Esophageal liposarcoma is an extremely rare tumor. Due to the nonspecific clinical manifestation and lack of experience, it is challenging to make a clear diagnosis before operation. Definite diagnosis of esophageal liposarcoma depends on histopathology, immunohistochemistry and molecular analysis.

Abstract
A 76-year-old woman was referred for 6 months of progressively worsening dysphagia and unintentional weight loss. An esophagogastroduodenoscopy demonstrated an area of extrinsic compression in the lower esophagus measuring 7 cm in greatest dimension. Contrast-enhanced computed tomography revealed a solid homogeneous mass in the lower middle/posterior mediastinum, laterally displacing the esophagus. Endoscopic ultrasound-guided fine-needle biopsy showed a hypocellular infiltrate of pleomorphic cells in a loose collagenous matrix. By immunohistochemistry, neoplastic cells were negative for epithelial, vascular, neural, and melanocytic markers. Fluorescent in situ hybridization detected MDM2 amplification, compatible with a diagnosis of dedifferentiated liposarcoma.

Abstract
Fibrovascular polyp is a rare non-epithelial esophageal tumor arising from submucosal layer and consisting of connective and adipose tissue, as well large number of vessels. Large tumors can cause dysphagia, vomiting, chest pain, shortness of breath and/or asthma, while giant neoplasms are potentially life threatening. Despite active introduction of minimally invasive treatment of patients with non-epithelial gastrointestinal tumors, there are still difficulties in surgical treatment of fibrovascular polyps. The patient with a giant fibrovascular esophageal polyp presented with cough, discomfort in the throat, impaired swallowing and episode of tumor migration into oropharynx. Examination confirmed giant highly vascularized esophageal fibrovascular polyp. A novel hybrid surgical technique (endoscopic submucosal dissection with laparoscopic removal of tumor) was applied. Eight-month follow-up revealed no complications. Favorable clinical result was achieved. A hybrid laparo-endoscopic approach in the treatment of patients with large fibrovascular polyps minimizes perioperative risks and improves postoperative outcomes.

Abstract
INTRODUCTION Giant fibrovascular esophageal polyp is a rare benign intraluminal tumour. The aim of this study is to perform a review of the most recent literature in order to describe and analyse the current range of possible diagnostics and treatment strategies. CASE REPORT We present two cases of giant fibrovascular esophageal polyp treated with a combined minimally invasive transluminal approach at Sanchinarro University Hospital. Further, we perform a literature review. CONCLUSION We present two cases of grant fibrovascular polyp submitted to minimally invasive transluminal approach. Furthermore, 54 original articles reporting 59 cases have been analysed. In the surgical group, an esophagotomy and polyp resection were performed in 31 (91 %) patients and a total esophagectomy in two patients (5,8 %). Severe morbidity occurred in two patients (5,8 %.) The median hospital stay was 9.25 days. A total of two (5,8 %) cases of recurrence have been registered. In the minimally invasive transluminal approach group, 27 patients had a polyp resection performed completely by endoscopy/transoral. There were no complications but there was one case of recurrence. CONCLUSION The transluminal approach is safe and should be considered also in the treatment of large esophageal polyps.

Abstract
BACKGROUND Liposarcoma is one of the most common adult mesenchymal tumors but is uncommon in the gastrointestinal tract and extremely rare in the stomach. Furthermore, the histological subtypes of liposarcoma usually reported in the stomach are well-differentiated or myxoid, and few reports have been issued on small-sized gastric liposarcomas resected endoscopically and followed up. Herein, we report a case of primary gastric dedifferentiated liposarcoma (DL) that was resected endoscopically.
CASE SUMMARY A 67-year-old female Korean patient was referred to our institution for further evaluation of a gastric submucosal tumor (SMT) located in the lesser curvature of the gastric body by esophagogastroduodenoscopy. Endoscopic ultrasound revealed a well-circumscribed, slightly heterogeneous, isoechoic, 17 mm × 10 mm sized mass originating from the third sonographic layer. Computed tomography showed no evidence of significant lymph node enlargement or distant metastasis. Endoscopic resection was undertaken using the snare resection technique after mucosal precutting to provide a definitive histopathologic diagnosis, which proved to be consistent with DL, based on its morphology and the immunoexpressions of MDM2 and CDK4. The patient was planned for surgery because the deep resection margin was positive for malignancy. After declining any invasive procedure or adjuvant treatment, the patient was placed under close follow-up, and at one year after endoscopic resection, remained disease free.
CONCLUSION This is the first reported case of a small primary gastric DL resected endoscopically and followed up. This report demonstrates that when diagnosis of a SMT is uncertain, the use of invasive techniques, including endoscopic resection, should be considered.

Abstract
We report five patients treated for esophageal fibrovascular polyps using a minimally invasive technique. Esophageal fibrovascular polyps are benign pedunculated submucosal tumors of considerable size. The treated polyps size ranged from 1.5 to 13 cm. The polyps were removed by relocation to the oral cavity under endoscopic control. No perioperative complications occurred after the treatment. The follow-up of patients after surgery was 9–89 months, with no evidence of polyp recurrence. Thus, the described treatment is safe but requires experience with endoscopy as well as esophageal surgery.

Sarcomas are rare tumours that represent less than 1% of all malignant tumours in adults. Liposarcomas are among the most common malignant mesenchymal tumours. They are preferentially located in the limbs and the retroperitoneum. Liposarcomas primarily arising in the digestive tract are exceptional with a few cases reported in the literature. Their clinical presentation is variable and the symptoms are not specific. Anatomopathological examination remains the gold standard for the diagnosis and the classification of these tumours, which are divided into 5 histological types according to the 5th edition of the WHO classification of soft tissue tumours. We report two observations of unusual digestive liposarcomas, located in the oesophagus and the colon, emphasizing the variability of the diagnostic challenges, depending on the clinical presentation, the histological type and the analysed material.

Abstract
The epidemiology and clinical management of esophageal carcinomas are changing, and clinical imagers are required to understand both the imaging appearances of common cancers and the pathologic diagnoses that drive management. Rare esophageal malignancies and benign esophageal neoplasms have distinct imaging features that may suggest a diagnosis and guide the next steps clinically. Furthermore, these imaging features have a basis in pathology, and this article focuses on the relationship between pathologic features and imaging manifestations that will help an informed imager maintain clinical relevance.

Abstract
BACKGROUND Esophageal lipomatous tumors, also reported as fibrovascular polyp, fibrolipoma, angiolipoma, and liposarcoma, account for less than 1% of all benign mesenchymal submucosal tumors of the esophagus. Clinical presentation and therapy may differ based on location, size, and morphology. A comprehensive and updated systematic review of the literature is lacking. METHODS A systematic review of the literature was performed according to PRISMA guidelines. Pubmed, Embase, Cochrane, and Medline databases were consulted using MESH keywords. Non-English written articles and abstracts were excluded. Sex, age, symptoms at presentation, diagnosis, tumor location and size, surgical approach and technique of excision, pathology, and morphology were extracted and recorded in an electronic database. RESULTS Sixty-seven studies for a total of 239 patients with esophageal lipoma or liposarcoma were included in the qualitative analysis. Among 176 patients with benign lipoma, the median age was 55. The main symptoms were dysphagia (64.2%), transoral polyp regurgitation (32.4%), and globus sensation (22.7%). The majority of lipomas (85.7%) were intraluminal polyps, with a stalk originating from the upper esophagus. Overall, 165 patients underwent excision of the mass through open surgery (65.5%), endoscopy (27.9%), or laparoscopy/thoracoscopy (3.6%). Only 5 (3%) of patients required esophagectomy. Of the 11 untreated patients with an intraluminal polyp, 7 died from asphyxia. Overall, liposarcoma was diagnosed in 63 patients, and 12 (19%) underwent esophagectomy. CONCLUSION Esophageal lipomatous tumors are rare but potentially lethal when are intraluminal and originate from the cervical esophagus. Modern radiological imaging has improved diagnostic accuracy. Minimally invasive transoral and laparoscopic/thoracoscopic techniques represent the therapeutic approach of choice.

Abstract
The pathologist's approach to gastroesophageal mesenchymal tumours has changed dramatically during the last 25 years. In particular, gastrointestinal stromal tumour (GIST) has evolved from a wastebasket mesenchymal tumour category to a precisely defined entity with an increasingly detailed genetic subclassification. This subclassification has brought gastrointestinal mesenchymal neoplasia into the realm of precision medicine, with specific treatments optimised for particular genetic subtypes. Molecular genetic data have also greatly improved our understanding of oesophageal mesenchymal tumours, including the discovery that so-called 'giant fibrovascular polyps' in fact represent a clinically distinctive presentation of well-differentiated liposarcoma. Here, we will focus on gastroesophageal mesenchymal tumours for which there have been recent developments in classification, molecular genetics or tumour biology: granular cell tumour, 'giant fibrovascular polyp'/well-differentiated liposarcoma, plexiform fibromyxoma, gastroblastoma and, of course, GIST.

Abstract
Esophageal lipoma is a rare neoplasm with heterogeneous and sometimes life-threatening clinical presentation. We report the case of two patients, a 77-year-old man and a 69-year-old woman presenting with heartburn and dysphagia, and with recurrent vomiting and asphyxia, respectively. Upper gastrointestinal endoscopy and computed tomography were highly suggestive of the diagnosis of esophageal lipoma and identified an intramural and an intraluminal pedunculated mass originating, respectively, from the distal and the cervical esophagus. The first patient was treated by laparoscopic transhiatal enucleation and the second by transoral endoscopic resection under general anesthesia. Both had an uneventful postoperative course and were discharged home on postoperative day 2. Minimally invasive excision of esophageal lipoma is feasible and effective. It may be life-saving in patients with pedunculated tumors who suffer from intermittent regurgitation of a bulky polypoid mass in the mouth causing asphyxia.

Abstract
Well-differentiated (WDL) and dedifferentiated liposarcomas (DL) of the pharynx, larynx and oral cavity are rare, often mimicking benign lipomatous neoplasms or non-lipogenic mesenchymal tumors. Cases of WDL/DL arising in the upper aerodigestive tract, exclusive of the cervical esophagus, were reviewed. Morphologic features, ancillary studies, including fluorescence in situ hybridization (FISH) studies for CPM/MDM2, and clinical data was catalogued. Eight WDL/DL (4 WDL, 4 DL); were identified in patients ranging from 32 to 77 years (median 52.5 years; 6 males, 2 females) with sites of origin including hypopharynx (5 cases), larynx (2 cases) and oral cavity (1 case). Six of the 8 cases were received for expert consultation, and the remaining 2 cases were initially misdiagnosed as benign lymphangiomatous or fibroepithelial polyps. Morphologically, 4 tumors had areas mimicking various non-lipomatous soft tissue tumors including nodular fasciitis, mammary-type myofibroblastoma, low-grade myofibroblastic sarcoma and undifferentiated pleomorphic sarcoma, 2 cases simulated benign hypopharyngeal polyps, and 1 lesion was notable for a dense lymphoplasmacytic infiltrate suggestive of hematolymphoid neoplasm or IgG4-related sclerosing disease. FISH showed amplification of CPM/MDM2 (8/8 cases). All cases (4/4) with longer than 1-year of follow-up recurred (45-118 months) with 1 tumor showing progression to DL. WDL/DL presenting in the upper aerodigestive tract are rare and diagnostically challenging. Awareness of the morphologic spectrum of WDL/DL coupled with appropriate use of MDM2 FISH is essential for accurate classification and management, as these tumors appear to have a high risk for local recurrence and eventual dedifferentiation in these anatomical locations.

Abstract
Pharyngeal liposarcomas are very rare; still more rare are dedifferentiated liposarcomas in the pharynx. An 82-year-old man presented with dysphagia, voice changes, weight loss, nasal regurgitation of liquids, and coughing spells. A 3.5 cm mass was identified in the hypopharynx. The mass was biopsied and diagnosed as a benign fibroepithelial polyp. Continued symptoms and airway obstruction prompted a pharyngectomy, and the mass was then diagnosed as dedifferentiated liposarcoma. Due to infrequency and subtle histological findings, liposarcomas of the head and neck can be misdiagnosed and recur.

Abstract
Primary gastrointestinal liposarcoma is rare, and information regarding this entity is largely based on single case studies. We report on 8 patients with primary liposarcoma of the gastrointestinal tract and review the pertinent literature. The cohort includes 6 men and 2 women who ranged in age from 51 to 81 years (median 68.5). Two tumors arose in the stomach, 4 in the small intestine, and 2 in the large intestine. Tumors ranged in size from 2.5 to 14.5 cm (median 7 cm), originated in the submucosa or muscularis propria of the intestinal wall, and frequently protruded into the bowel lumen, resulting in mucosal ulceration and luminal obstruction. Six tumors were dedifferentiated liposarcomas, and 2 were well-differentiated liposarcoma. Surgical excision was performed on all tumors except for 1 case of dedifferentiated liposarcoma. On follow-up, 1 patient with dedifferentiated liposarcoma developed a lytic sacral lesion suspicious for metastasis 4 months after resection of the primary, and another underwent marginal resection and presented with recurrence 4 years later, had tumor re-resection, and was considered disease-free at 6 weeks postsurgery. A third patient with dedifferentiated liposarcoma was alive with unknown disease status at 17 months following surgery, and another patient with dedifferentiated liposarcoma was alive without evidence of disease at 30 months following surgery. No follow-up information on the remaining patients is available. Overall, liposarcomas of the intestinal tract are most frequently high-grade dedifferentiated tumors that are biologically aggressive and require surgical excision with widely negative margins to help reduce the risk of local recurrence and dissemination. Important in the differential diagnosis is malignant gastrointestinal stromal tumor. Care must be taken not to misdiagnose one entity for the other because the correct diagnosis carries important therapeutic implications.

Abstract
Giant oesophageal liposarcomas, a rare but important cause of oesophageal tumours. A review of the current literature focusing on resection techniques. Shift in the treatment paradigm in recent years to endoscopic resection techniques. Decision on type of resection technique depends on tumour characteristics and location.
Introduction and presentation of case Liposarcomas are rare causes of oesophageal tumours, accounting for <1% of tumours. We present a case of a dedifferentiated oesophageal liposarcoma arising from a giant fibrovascular polyp for which resection was performed via a left cervical oesophagostomy with transgastric retrieval of tumour. We also review the existing literature focusing on discussion of resection techniques. Discussion To date, 62 cases of oesophageal liposarcoma have been reported in the literature. They usually occur in males (74.2%), with a median age of 66 years (range 38–84 years). Such tumours present most commonly with dysphagia (69.4%); usually arise from the cervical oesophagus (79%), and are well-differentiated. Treatment options include surgery and recently, endoscopic resection techniques such as submucosal dissection (ESD). Conclusion Giant oesophageal liposarcomas are very rare tumours. Such tumours are usually polypoid, arising from a pedicle. As such, resection techniques have shifted away from oesophagectomy to less invasive means such as endoscopic resection or oesophagostomy. Decision on type of resection technique depends on tumour characteristics and location; with the guiding principle being resection with clear margins in order to prevent local recurrence.

Abstract
Atypical lipomatous tumours (ALT) of the oesophagus are rare malignant tumours that are found most commonly in the cervical oesophagus. They are commonly misdiagnosed as giant fibrovascular polyps of the oesophagus (GFP). The differentiation between these clinical entities is important as ALTs are malignant tumours with the potential for local recurrence and metastases. We present a case of an ALT which was misdiagnosed as a GFP. The correct diagnosis was made on histological examination of the resected specimen, and confirmed by immunohistochemistry. The tumour cells extended to involve the resection margins, highlighting the need to consider this diagnosis when dealing with all oesophageal polyps, and ensure complete resection of these tumours.

Abstract
Soft tissue sarcomas represent an extremely rare cause of esophageal masses, and undifferentiated sarcomas are rarer. The proportion of dedifferentiated liposarcomas (DDL) is even lower. The case of a 58-year-old male who complained of dysphagia and was found to have an 18-centimeter long esophageal mass/polyp on esophagogastroduodenoscopy is presented. The lesion was resected endoscopically and a diagnosis of DDL was confirmed by fluorescence in situ hybridization. Due to its rarity, the treatment experience with esophageal DDLs is limited. However, based on our experience, endoscopic resection of the lesion can be considered as the treatment of choice when feasible. We performed a review of the literature to identify and analyze similar reported cases.

Abstract
A fibrovascular polyp is a rare benign pseudotumor of the esophagus or the hypopharynx. It comes to light through dysphagia and can lead to death by asphyxiation. CT scan and MRI suggest this diagnosis by highlighting a lobed endoluminal tumor primarily composed of adipose tissue and pedicled on a vessel. Anatomo-pathological analysis of biopsies can exclude liposarcoma, the main differential diagnosis. Treatment consists in complete reconstruction by cervicotomy.
