Ann Coloproctol 2023; 39:275-279. [PMID: 34228911 PMCID: PMC10338165 DOI: 10.3393/ac.2020.00836.0119] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2020] [Revised: 05/06/2021] [Accepted: 05/08/2021] [Indexed: 10/20/2022] Open
Abstract
We report a case about successful surgical treatment of a granular cell tumor in the ascending colon. A 36-year-old man underwent screening colonoscopy. An endoscopic examination revealed a 10-mm yellowish and hemispheric mass in the ascending colon, and lower endoscopic ultrasonography revealed a hypoechoic-to-isoechoic mass invaded the submucosal layer. The mass was suspected to be a colonic carcinoid tumor. Based on the preoperative evaluation, endoscopic complete resection was considered difficult. Therefore, the lesion was removed via laparoscopic right hemicolectomy. Histological examination revealed that the tumor consisted of nests of polygonal cells with abundant granular eosinophilic cytoplasm. Immunohistochemical staining revealed diffuse positivity for S100 and CD68. Therefore, the tumor was diagnosed as a granular cell tumor. We suggest that surgical resection should be considered if it is located in the thin-walled ascending colon prone to perforation, difficult to rule out malignant tumor due to submucosal invasion, or to remove endoscopically.

Abstract
A 12-year-old mixed-breed dog was presented for a follow-up examination after ablation of an auricular mast cell tumour. An abdominal ultrasound and computed tomography were performed and an irregular, ill-defined and partially mineralised lesion was observed around the caudal duodenal flexure without evidence of metastasis. The cytologic examination was highly suggestive of a granular cell tumour. Partial surgical ablation with histological and immunohistochemical examination of the lesion confirmed the diagnosis. According to our review of the literature, this is the first report documenting an abdominal granular cell tumour in a dog.

Abstract
INTRODUCTION and importance: Granular cell tumor (GCT) is a benign, mesenchymal tumor that originates from Schwann cells. CASE PRESENTATION A 75-year-old Japanese woman was referred to our hospital due to epigastric discomfort. Upper gastrointestinal endoscopy revealed an ulcerated cancer lesion, approximately 1.2 cm in diameter, at the angle of the stomach in the posterior gastric wall and a yellowish submucosal tumor, 5 mm in diameter, near an anal ulcerated lesion. Based on these findings, the patient was scheduled for laparoscopic distal gastrectomy and lymph node dissection. The pathological diagnosis was a moderately differentiated tubular adenocarcinoma invading mucosal stroma without lymph node metastasis and GCT in the stomach. Tumor cells were positive for S-100 and were consistent with the characteristics of GCT. CLINICAL DISCUSSION To the best of our knowledge, this is an extremely rare case with reports of only 6 cases of such a combination, including our case. CONCLUSIONS We believe that the coexistence of a GCT and gastric cancer in our patient was accidental and that there was no relation between them.

Abstract
INTRODUCTION Granular cellular tumors are unusual lesions that can occur in the gastrointestinal tract, where they localize most commonly to the esophagus followed by the colon. AREAS COVERED We report a case of a young man with a sub-epithelial lesion of the ascending colon, removed by endoscopic submucosal dissection. Histological examination revealed a granular cellular tumor without features of malignancy. We present a systematic review of the English literature evaluating granular cellular tumors of lower gastrointestinal tract. EXPERT COMMENTARY These tumors are usually asymptomatic and discovered incidentally during endoscopy performed for other reasons. Though their histological behavior is usually benign, 1-2% are malignant. Therefore, it is important that these lesions are excised and adequately pathologically characterized.

Abstract
Background Granular cell tumors (GCT) in the gastrointestinal tract are rare. Herein, we describe a case of a gastric GCT diagnosed preoperatively by endoscopic ultrasound-guided fine needle aspiration biopsy (EUS-FNAB) and successfully resected by single-incision laparoscopic surgery (SILS). Case presentation A 46-year-old Japanese woman had a tumor located in the angle of the stomach that was approximately 1.5 cm in diameter. Abdominal computed tomography (CT) revealed a submucosal tumor (SMT), which was finally diagnosed as a gastric GCT using EUS-FNAB. The tumor was not identified by CT 1 year and 4 months before diagnosis; therefore, because there was a possibility that the tumor was malignant, we performed surgical wedge resection using SILS. The patient had an uneventful recovery postoperatively and was discharged without complications 3 days after surgery. The tumor was pathologically diagnosed as a benign GCT that remained within the muscular layer. No recurrence or complications have occurred in the first 16 months since the surgery. Conclusion Because gastric GCTs are generally benign and are rarely associated with lymph node metastasis, SILS seems to be a safe and feasible surgical approach for treating GCTs.

Abstract
Granular cell tumor (GCT) is a rare soft tissue neoplasm. At present, there is limited information available on the incidence, diagnosis, and treatment of GCTs. Therefore, we perform magnetic resonance imaging (MRI) of a perianal GCT case and review the literature of other reported cases to obtain a more comprehensive understanding of the disease. Here, we describe a rare case of perianal GCT in a 53-year-old female who presented with recurrent abdominal pain. Contrast-enhanced MRI demonstrated a well-defined perianal GCT mass, and the diagnosis was confirmed by immunostaining after mass excision. During a 10-month follow-up, there had been no evidence of recurrence. In addition, we discussed the findings of other perianal GCT cases, with regard to their age, gender, MRI analysis results, pathologic features, and treatment outcomes.

Abstract
Granular cell tumors (GCTs) are uncommon tumors. They are believed to be neuronal in origin and are usually found in the head and/or neck area of the body. They have also been reported in various locations of the gastrointestinal (GI) system, usually discovered during routine screening colonoscopy. We report a case of GCT in a 58-year-old asymptomatic African American female as a metachronous tumor of a well-differentiated adenocarcinoma of the sigmoid colon, which was an incidental finding in screening colonoscopy. To our knowledge, this is the first case with GCT identified as a metachronous tumor following an adenocarcinoma of the colon.

Abstract
A 68-year-old woman was referred to our hospital for the treatment of bile duct stone, pancreatic tumor, and pancreatic cysts. First, bile duct stone was removed using endoscopic retrograde cholangiopancreatography. By abdominal contrast-enhanced computed tomography, a 12-mm diameter tumor was found in the pancreatic body. The tumor was isodense compared with the surrounding pancreatic parenchyma in the non-contrast phase and poorly enhanced in the arterial phase; it exhibited gradual enhancement from the portal vein phase to the late phase. Numerous pancreatic cysts were also observed by contrast-enhanced computed tomography. By magnetic resonance imaging, the tumor was hypointense in T1-weighted images, isointense in T2-weighted images, and hyperintense in diffusion-weighted images. By magnetic resonance cholangiopancreatography, the main pancreatic duct was not dilated, and pancreatic cysts communicated with the main pancreatic duct. The pancreatic cysts were diagnosed as branch-type intraductal papillary mucinous neoplasm. Histopathologic assessment of the specimens obtained by endoscopic ultrasound-guided fine-needle aspiration revealed the tumor as benign pancreatic granular cell tumor. The patient was followed up without surgical resection. On contrast-enhanced computed tomography at 6 months after admission, the tumor did not show any changes in diameter or characteristics.

Abstract
A granular cell tumor (GCT) is an uncommon mesenchymal lesion that rarely occurs in the colon and the rectum. We describe the case of 51-year-old man with a 2-cm-sized rectal GCT 10 cm above the anal verge that was incidentally detected after a screening colonoscopy. Preoperative radiologic studies demonstrated a suspicious submucosal rectal mass with mesorectal fat infiltration, but without circumferential resection margin threatening, extramural vessel invasion, and regional lymph-node enlargement. The tumor was resected by using a transanal endoscopic operation (TEO) without immediate postoperative complications. The final pathology revealed that the tumor consisted of a GCT that had invaded the subserosa with clear margins. It had no other risk factors for malignancy according to Fanburg-Smith criteria. We systematically reviewed the English literature by using PubMed and Google Scholar. This report may be the first documented case in the literature to describe a TEO for a GCT that had invaded the subserosa in the rectum.

Abstract
Granular cell tumor (GCT) also known as Abrikossoff's tumor is a benign neoplasm that is usually seen in the fourth to sixth decades of life with slight female preponderance. It is most frequently seen in the oral cavity, skin, and subcutaneous tissue. Gastrointestinal tract involvement is uncommon, in which esophagus is the most commonly affected site. There are case reports of GCT in stomach, appendix, colon and rectum. In this article, we report a case of GCT involving cecum. The cell of origin in GCT is controversial. There are various pools of thoughts regarding its histogenesis, the details of which are reviewed in this article with emphasis on the diagnostic difficulties encountered in this tumor.

Abstract
Gastrointestinal granular cell tumors (GCTs), usually benign, soft-tissue tumors, are thought to arise from Schwann cells that may occur at many sites. Only 5-7% of these lesions are detected in the gastrointestinal tract. Histologically, it is composed of sheets or nests of plump round or polygonal cells having abundant slightly amphophilic granular cytoplasm with centrally located uniform pyknotic nuclei and immunohistochemical staining for S-100 protein supports the proposed derivation from Schwann cells. In this study, we reported a case of a solitary GCT of the stomach that was completely removed after endoscopic submuscosal resection.

Abstract
Granular cell tumor is a soft tissue neoplasm that originates in the nervous system and arises at virtually any body site, but is mainly found in the skin, oral cavity or digestive tract. Most are benign and reportedly malignant cases are rare, occurring in only 1% or 2% of cases. We report on our findings in six patients who developed granular cell tumor in the mammary gland, esophagus, subcutaneous tissue and muscle. Of six patients, two had granular cell tumor located in the breast, two in the submucosa of the esophagus, and the other two under the skin of the left axillary cavity and in the right latissimus dorsi muscle, respectively. One of the two patients with tumor in the submucosa of the esophagus also had esophageal cancer. Patients' age ranged from 41 to 70 years (average, 59.1 years). Two patients with tumor in the submucosa of the esophagus were men, and the others were women. All of them were given a diagnosis of granular cell tumor by tissue biopsy and examination of excised specimens, but no evidence of malignancy was found. No recurrence has been noted in the patients who underwent surgical tumor removal.

Abstract
Granular cell tumor (GCT) is a rare tumor that originates from the Schwann cells in the skin, soft tissues, and internal organs. Usually, GCTs are clinically benign, although malignant and multifocal forms are very rarely known to occur. Cases of GCT of the perianus are rare, and thus far, no study has reported synchronous GCTs of the perianus and the chest wall. We report a case of a 31-year-old woman with synchronous GCTs of the perianus and the chest wall to have a mind of consideration of the possibility of GCT in the differential diagnosis of perianal tumor.

Abstract
Granular cell tumor (GCT) was first described by Abrikossof in 1926. This tumor is a benign neoplasm of unclear histogenesis that is generally believed to be of nerve sheath origin. GCT is not common and most often affects the tongue, skin, and soft tissue, although it may occur anywhere in the body. Gastrointestinal tract involvement, and especially that of the colon, is very rare. This usually benign tumor appears as a submucosal nodule, measuring less than 2 cm in diameter and is often found incidentally during colorectal examinations. We describe the case of a 27-year-old man with a GCT in the cecum that was detected after a screening colonoscopy. Endoscopic examination revealed a yellowish submucosal tumor, 0.7 cm in diameter. An endoscopic mucosal polypectomy was done for histological confirmation and treatment.

Abstract
A 60-year-old man had a positive fecal occult-blood test on a medical check-up. Colonoscopy revealed a yellowish-white submucosal tumor 8 mm in diameter in the rectum. Endoscopic ultrasonography showed a well-demarcated mass with a homogeneous, low-level, internal echo in the second to third layers of the rectal wall. A carcinoid tumor was suspected, and the mass was resected endoscopically. Histopathological examination revealed a granular-cell tumor. Gastrointestinal granular-cell tumors rarely arise in the rectum, and the preoperative diagnosis of small lesions is often difficult. In our patient, granular-cell tumor was difficult to differentially diagnose because the endoscopic and endoscopic ultrasonographic findings closely resembled those of carcinoid tumor. Interestingly, the endoscopic characteristics of the rectal granular-cell tumor in our patient resembled those of a carcinoid tumor.

Abstract
A granular cell tumor (GCT) is a benign neoplasm of unclear histogenesis that is generally believed to be of nerve sheath origin. GCT is not common and most often affects the tongue, skin and soft tissue, although it may occur anywhere in the body. We experienced a case of GCT that arose in the cecum of a 55-year-old man. The GCT was removed by laparoscopic resection. In addition to the tumor, endoscopic examination revealed the presence of a 5-mm-polyp in the descending colon and multiple tiny polyps in the sigmoid colon and rectum. Histological examination demonstrated a cecal tumor 1.5 cm x 1.0 cm x 0.7 cm with a hard consistency; in cut sections, mixed cells with yellowish and whitish portions were seen. The tumor was located between the mucosa and subserosa, and was composed of plump histiocyte-like tumor cells with abundant granular eosinophilic cytoplasm, which were immunoreactive for S-100 protein, vimentin, neuron-specific enolase, inhibin-alpha and calretinin. The tumor showed extensive hyalinization and focal dystrophic calcification. Immunohistochemical profiles did not confirm any particular cell type for the histogenetic origin of the GCT, including a nerve sheath origin. Extensive hyalinization and calcification showing involution of tumor cells suggest benign clinical behavior of GCT.

Abstract
Although colorectal granular cell tumors (GCTs) are rare, their incidental finding has increased as the use of diagnostic colonoscopy has become more common. Here we describe the case of a 41-yr-old man with a GCT in the descending colon that was detected after a screening colonoscopy. Endoscopic examination revealed a yellowish submucosal tumor, 13x12 mm in diameter, in the descending colon. Endoscopic mucosal resection (EMR) followed by histological examination revealed that the tumor was composed of plump histiocyte-like cells with an abundant granular eosinophilic cytoplasm and small round nuclei. The tumor cells expressed S-100 protein and stained with periodic acid-Schiff, but were negative for desmin and cytokeratin. The resected tumor was diagnosed as a GCT. Colonoscopists should consider the possibility of GCT in the differential diagnosis of yellowish submucosal tumors of the colon. In such patients, EMR seems to be a feasible and safe approach for diagnosis and treatment.

Abstract
Granular cell tumor (GCT) is an uncommon esophageal neoplasm. It commonly presents as a nonspecific painless mass. The purpose of this study is to describe our experience with 5 patients newly diagnosed with GCT at VA Medical Center in Memphis, Tennessee from February 2001 to June 2005. Clinical manifestation, endoscopic appearance, histology, different modalities of treatment and prognosis are discussed. Based on this experience, we conclude that GCTs are relatively rare in occurrence. They usually present as a firm to hard submucosal nodule on esophagogastroduodenoscopy. Diagnosis can be made by endoscopic biopsy in most cases. Treatment options include endoscopic surveillance, endoscopic resection, or surgery. The usual course of GCTs is benign.

Abstract
This review is part two of three, which will present an update on the classification of gastrointestinal submucosal tumors. Part one treats of the diagnosis and part three of the therapeutic methods regarding gastrointestinal submucosal tumors. In the past there has been some confusion as to the classification of gastrointestinal submucosal tumors. Changes in classifications have emerged due to recent advances in mainly immunohistochemistry and electron microscopy. The aim of this paper is to update the reader on the current classification. Literature searches were performed to find information related to classification of gastrointestinal submucosal tumors. Based on these searches the twelve most frequent submucosal tumor types were chosen for description of their classification. The factors that indicate whether tumors are benign or malignant are mainly size and number of mitotic counts. Gastrointestinal stromal tumors are defined mainly by their CD117 positivity. In the future, there should be no more confusion between gastrointestinal stromal tumors and other types of submucosal tumors.

Abstract
This review is part three of three and will present an update on the therapeutic options and procedures concerning gastrointestinal (GI) submucosal tumors (SMTs). The aim of this paper is to investigate the treatments of GI SMTs and to present a case of a gastrointestinal stromal tumor (GIST). Literature searches were performed to find information on therapy for GI SMTs. Based on these searches, the optimal therapeutic procedures could be outlined. The choice of treatment of localized tumors is endoscopic resection if possible or, alternatively, laparoscopic resection or surgical resection by an open procedure. However, benign SMTs should only be excised if symptoms are present, and GISTs should be treated with particular precautions. Irresectable or recurrent GISTs may be successfully treated with the tyrosine kinase inhibitor, imatinib.

Abstract
This review is part one of three, which will present an update on diagnostic procedures for gastrointestinal (GI) submucosal tumors (SMTs). Part two identifies the classification and part three the therapeutic methods regarding GI SMTs. Submucosal tumors are typically asymptomatic and therefore encountered incidentally. Advances in diagnostic tools for gastrointestinal submucosal tumors have emerged over the past decade. The aim of this paper is to provide the readers with guidelines for the use of diagnostic procedures, when a submucosal tumor is suspected. Literature searches were performed to find information on diagnostics for gastrointestinal submucosal tumors. Based on the searches, the optimal diagnostic procedures and specific features of the submucosal tumors could be outlined. Standard endoscppy, capsule endoscopy and push-and-pull enteroscopy (PPE) together with barium contrast X-ray do not alone provide sufficient information, when examining submucosal tumors. Endoscopic ultrasound (EUS), computed tomography (CT), magnetic resonance imaging (MRI) and fluorodeoxyglucose-labeled positron emission tomography (FDG-PET) are recommended as supplementary tools.

Abstract
Granular cell tumor (GCT) was described for the first time by Abrikosoff in 1926. It is a relatively rare neoplasm that may occur at many sites, but most commonly in the skin or soft tissues. The occurrence of GCT in the gastrointestinal tract is rare, accounting approximately for 8% of all tumors, among which the most common site is the esophagus, whereas gastric localization is very rare. Gastric GCTs can be solitary or, more frequently, associated with other gastrointestinal localization. Although GCTs are usually clinically and histologically benign, some malignant cases have been reported. Histologically, these tumors consist of polygonal and fusiform cells disposed in compact “nests” and immunohistochemical staining for S-100 protein supports the proposed derivation from Schwann cells. A correct preoperative diagnosis of this tumor can only be made in 50% of all patients and it is always based on endoscopic biopsy. Laparoscopic or conventional wedge resection represents the treatment of choice. In this study, the authors reported a case of a 49-year-old woman with a solitary granular cell tumor of the stomach with infiltrative pattern, successfully treated with surgical resection. A review of literature is also presented with emphasis on diagnostic criteria concerning the malignant form.

Abstract
Granular cell tumor (GCT) is uncommon in the colon and rectum. Here we report a case of GCT in the transverse colon. A 48-year-old male patient underwent a screening colonoscopy. A yellowish sessile lesion, about 4 mm in diameter, was found in the transverse colon. An endoscopic snare resection was performed without complication. Histological examination revealed the tumor consisted of plump neoplastic cells with abundant granular eosinophilic cytoplasm containing acidophilic periodic acid Schiff-positive, diastase-resistant granules. Immunohistochemical analysis showed the tumor cells expressed S-100 protein and neuron-specific enolase. Thus, the resected tumor was diagnosed as a GCT. Since GCTs are usually benign, endoscopic resection constitutes an easy and safe treatment. Colonoscopists should consider the possibility of GCT in the differential diagnosis of submucosal tumors of the colon.
