Hashizume R, Matsuda S, Nagai M, Hirata K, Imai H, Kushima R. An unusual presentation of chordoma as a pyloric ring submucosal tumor: The first case report of a primary gastrointestinal lesion in humans. Int J Surg Case Rep 2022; 94:107032. [PMID: 35398781 PMCID: PMC9006247 DOI: 10.1016/j.ijscr.2022.107032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2022] [Revised: 04/01/2022] [Accepted: 04/02/2022] [Indexed: 11/23/2022] Open
Abstract
Introduction and importance Chordomas are rare malignant bone neoplasms that are presumed to arise from chordal remnants in the fetal stage and typically occur along the axial skeleton. The extra-skeletal chordomas reported to date include soft tissue of the extremities and nasopharynx. Chordoma arising from the gastrointestinal wall has not been previously described. Case presentation We report on a 42-year-old man with primary chordoma presenting as a gastroduodenal submucosal tumor centered on the pyloric ring. The patient was consistently asymptomatic, and the tumor was an incidental finding. However, during a follow-up at approximately 1.6 years, an increase in tumor size was identified on computed tomography (CT), and surgical resection was performed without a definite pathologic diagnosis. The patient was successfully treated with distal gastrectomy, and the histological diagnosis was a conventional chordoma. The diagnosis was confirmed via immunohistochemical staining for brachyury, pan-cytokeratin, S-100, and SOX9. Postoperative CT and magnetic resonance imaging revealed no recurrence or metastasis during the 1.5-year follow-up period. Clinical discussion Primary chordomas of the digestive tract are rare. Embryologic development of the notochord does not explain the existence of remnants in the gastrointestinal wall. Moreover, notochordal remnants, as precursors of chordoma, were not identified in the current case. The gastroduodenal chordoma may not have originated from embryonic notochordal remnants but through aberrant brachyury activation without a notochordal precursor. Conclusion We report the first case of primary gastrointestinal chordoma in humans. The tumor was completely removed surgically, without postoperative recurrence. This is a case of primary gastrointestinal submucosal chordoma in a 42-year-old man Chordoma is a rare bony tumor that most frequently affects the axial skeleton Extra-skeletal chordomas are extremely rare in any species This is the first report of primary chordoma of the digestive tract in humans

Abstract
Sacrococcygeal chordoma is a rare malignant bone tumor. Although there are tough membranes such as the periosteum and presacral fascia (which resist transgression by the tumors), chordoma usually invades the rectal wall. The serious problem with these tumors is the late diagnosis and its high likelihood to become enlarged. The main treatment options for this tumor is surgical resection, radiotherapy, and chemotherapy. Due to the tumor vicinity to important organs such as bladder and its neurovascular structures, it makes surgical excision extremely challenging. The aim of this study is to describe a 50-year-old man with a giant sacrococcygeal mass. The novelty of this case report is the huge and unique size of the tumor which has not reported previously as well the special surgical approaches performed to remove the tumor.

Abstract
Extra-axial chordomas in the pediatric population are extremely rare and diagnostically challenging; only four cases have been previously reported with ages ranging from 13 to 20 years. We report a primary extra-axial chordoma involving the soft tissue directly dorsal and ulnar to proximal phalanx in the right thumb of a 12-year-old girl who presented with worsening right thumb pain for 1.5 years. The diagnosis was confirmed by excisional biopsy demonstrating proliferation of large, polygonal epithelioid cells with diffuse expression of pan-cytokeratin and brachyury. The patient required repeat excision for local recurrence seven months later. Since then, she has remained disease free through 15 months surveillance. Extra-axial chordomas share the same histopathological and immunohistochemical characteristics with their axial counterparts and should be considered in the differential diagnosis for any extra-axial bone or soft tissue mass with epithelioid morphology.

Abstract
Extra-axial chordoma is a rare neoplasm of extra-axial skeleton and soft tissue that shares identical histomorphologic and immunophenotypic features with midline chordoma. While genetic changes in conventional chordoma have been well-studied, the genomic alterations of extra-axial chordoma have not been reported. It is well known that conventional chordoma is a tumor with predominantly non-random copy number alterations and low mutational burden. Herein we describe the clinicopathologic and genomic characteristics of six cases of extra-axial chordoma, with genome-wide high-resolution single nucleotide polymorphism array, fluorescence in situ hybridization and targeted next-generation sequencing (NGS) analysis. The patients presented at a mean age of 33 years (range: 21-54) with a female to male ratio of 5:1. Four cases were histologically conventional type, presented with bone lesions and three of them had local recurrence. Two cases were poorly differentiated chordomas, presented with intra-articular soft tissue masses and both developed distant metastases. All cases showed brachyury positivity and the two poorly differentiated chordomas showed in addition loss of INI-1 expression by immunohistochemical analysis. Three of four extra-axial conventional chordomas showed simple genome with loss of chromosome 22 or a heterozygous deletion of SMARCB1. Both poorly differentiated chordomas demonstrated a complex hyperdiploid genomic profile with gain of multiple chromosomes and homozygous deletion of SMARCB1. Our findings show that heterozygous deletion of SMARCB1 or the loss of chromosome 22 is a consistent abnormality in extra-axial chordoma and transformation to poorly differentiated chordoma is characterized by homozygous loss of SMARCB1 associated with genomic complexity and instability such as hyperdiploidy.

Abstract
Chordomas are rare bone malignancies that are thought to arise from remnants of the notochord and usually are located in the axial skeleton. Immunophenotypical matching neoplasms primarily found in appendicular locations, referred to as extra-axial chordoma, are rarely encountered by radiologists, surgeons, and pathologists. Only a few of these cases have been described in the literature with only one intra-articular case with involvement of the knee joint. We present the first case of an intra-articular extra-axial chordoma of the wrist. Diagnostic imaging patterns were initially ambiguous and histopathological reprocessing was crucial in order to determine the diagnosis of an intra-articular neoplasm with co-expression of cytokeratins, S-100 protein, and brachyury.

Abstract
BACKGROUND Extra-axial chordomas are exceedingly rare malignant tumours. Herein, we present the first case of an extra-axial chordoma in the gingivae. METHODS AND RESULTS A 21-year-old man presented with a suspected chordoma in the upper right gingiva. Diagnosis was difficult; however, owing to strong expression of the chordoma marker brachyury, extra-axial chordoma was ultimately diagnosed. The tumour was completely resected without performing a facial incision. To ensure its safety and effectiveness, the surgical procedure was simulated several times before its performance using a three-dimensional (3D) model. Twenty-four months after surgery, the patient remains disease-free. CONCLUSION A diagnosis of extra-axial chordoma can be confirmed by immunohistochemical staining for brachyury.

Abstract
Poorly differentiated chordomas are rare musculoskeletal tumors. Case 1. A 42-year-old lady presented with quadriparesis of 2 months' duration. Radiologic imaging disclosed a soft tissue mass in her left prevertebral- and paravertebral cervical region. Case 2. A 4-year-old male child presented with neck pain and restricted head movements of 1-year duration. Radiologic imaging revealed a contrast enhancing, paraspinal soft tissue mass in his cervical region. Microscopic examination in both the cases revealed a cellular malignant tumor composed of moderate to markedly pleomorphic cells with interspersed mitotic figures, along with focal myxoid change and necrosis. By immunohistochemistry, tumor cells in both cases were diffusely positive for pan cytokeratin (AE1/AE3) and brachyury, whereas these were negative for INI1/SMARCB1. Tumor cells in the second case were also positive for glypican3. The first case developed pulmonary metastasis, while the second case developed recurrence. Poorly differentiated chordomas are uncommon tumors, invariably characterized by loss of INI1. These tumors can be rarely seen in adults and need to be differentiated from their diagnostic mimics, in view of treatment implications and their relatively aggressive clinical outcomes.

Abstract
Extra-axial chordoma is a chordoma that occurs in non-axial locations. It is a very rare tumor, with 20 cases reported to date; 14 in bone and six in soft tissue. Of the 14 skeletal extra-axial chordomas, ten were intramedullary and four were intracortical. We report the first case of parosteal extra-axial chordoma arising in the second metacarpal bone, expressing brachyury on immunohistochemical analysis, and describe the pathologic and radiologic findings. We suggest that extra-axial chordoma can occur in parosteal bone lesions or the hand, without features of bone distribution or bone-specific sites.

Abstract
Chordomas are rare, locally aggressive notochordal tumors, which most frequently occur in the neuraxis. We describe the case of a 74-year-old male with a history of renal cell carcinoma, who presented with a slowly enlarging mass in his left leg. While the clinical history and imaging suggested metastatic renal cell carcinoma, immunohistochemical staining with brachyury ultimately made the diagnosis of extra-axial chordoma. At 74 years of age, our patient is the oldest ever reported with bony extra-axial chordoma objectively confirmed by brachyury staining. A detailed case discussion and a review of the available literature on this rare clinicopathologic entity are provided.
