Postoperative Development of Desmoid Tumor After Surgical Correction of Adult Spinal Deformity: Case Report and Review of Literature

Paraspinal Desmoid Tumor in a Pediatric Patient with No Surgical History: A Case Report

Desmoid tumors are locally aggressive, benign neoplasms originating in connective tissues. Although the exact pathophysiology remains unknown, antecedent trauma or surgery are believed to be important contributing factors. The occurrence of paraspinal desmoid tumor in pediatric patients is extremely uncommon. Here, we present an exceedingly rare case of a pediatric patient with no surgical or family history who developed a paraspinal desmoid tumor. A 9-year-old female patient presented with 4 months of progressive back pain, right lower extremity weakness, and numbness. Spinal imaging revealed a left epidural paraspinal mass compressing her thoracic spinal cord and extending into the left thoracic cavity. A multidisciplinary approach with neurosurgery and thoracic surgery enabled gross total resection of the lesion. The patient had complete resolution of her symptoms with no signs of residual tumor on postoperative imaging. Pathology revealed a desmoid tumor that avidly stained for beta-catenin. On her last follow-up, she developed a recurrence, to which she was started on sorafenib therapy. Desmoid tumors are rare connective tissue neoplasms that often occur after local tissue trauma, such as that caused by surgery. This report presents a rare case of a pediatric paraspinal desmoid tumor that occurred in a patient with no surgical or family history. Such tumors should undergo surgical resection for symptomatic relief and tissue diagnosis. Close clinical and radiographic surveillance are essential in these patients due to the high recurrence rates of desmoid tumor.

Postoperative lumbar fusion paraspinal desmoid tumor case report

Desmoid tumors are rare soft tissue tumors with slow growth and high recurrence rates. They typically arise sporadically in the abdominal wall or retroperitoneum, with a few rare cases reported after trauma and surgery. Postoperative desmoid tumors in adults are very rare with only 7 reported cases involving the paraspinal location. This is the first reported case of a male patient with a postoperative paraspinal desmoid tumor.

Sporadic desmoid fibromatosis of the neck after dorsal spondylodesis of the cervical spine

Background:

Rare soft-tissue tumors, termed desmoid fibromatosis (DF), are comprised proliferated spindle cell fibroblasts and myofibroblasts embedded in a prominent collagenous stroma. They can occur either sporadically, due to prior trauma or surgery, or may have a genetic component. Clinically, DF has a high infiltrative growth/ local recurrence rate, but does not metastasize.

Case Description:

A 58-year-old male underwent a C5-C7 laminectomy/instrumented fusion. Two years later, he presented with a large gross swelling on the right side of the neck. The lesion was removed and proved to histologically consist of DF. Within the first postoperative 12 months, tumor did not recur.

Conclusion:

Sporadic DF may follow trauma or prior surgery. Symptomatic tumors are treated by surgical en bloc resection (preferably R0). If lesions are inoperable, partially resected, or recur, different hormonal/ chemotherapeutic systematic treatment options are available (e.g., tamoxifen or tyrosine kinase inhibitors). In the future, better molecular understanding of DF likely offers additional therapeutic approaches (e.g., immune checkpoint inhibitors).

Postoperative Recurrent Paraspinal Fibromatosis after Resection of Cervical Meningioma and Review of Literature

The extra-abdominal deep fibromatoses also called as desmoid tumor (DT) are rare musculoaponeurotic, histologically benign tumoral soft tissue lesions which are locally aggressive with high rate of recurrence and no metastatic potential. Here, we describe a rare case of postoperative paraspinal fibromatosis in female child after aciurgy of intraspinal cervical meningioma. The lesion was incidentally detected in routine follow-up study and showed significant interval growth over a period of 1 year. Surgical resection was performed after histopathological confirmation; however, recurrence was observed. Hitherto only seven cases of postoperative paraspinal fibromatosis have been reported in the literature. To the best of authors' knowledge, this report is the first case of postoperative fibromatosis in cervical spine after resection of meningioma. The aim of the case report is to emphasize the clinical scenario for suspicion of fibromatosis, magnetic resonance imaging clues, and multidisciplinary treatment strategy which has shifted toward initial active surveillance.

A Rare Paraspinal Desmoid Tumour following Instrumented Scoliosis Correction in an Adolescent

Desmoid tumours are benign neoplasms of myofibroblasts, often occurring after soft-tissue trauma. Rarely, desmoid tumours can occur following operative intervention, including spine surgery. In this case report, we describe the first reported case of desmoid tumour following scoliosis corrective surgery in an adolescent.
