Synovial sarcoma is a malignant mesenchymal neoplasm which commonly occurs in the extremities of adults. We report on a 12-days-old boywho presented to the department of paediatric surgery at Khartoum teaching hospital with a biphasic synovial sarcoma in the lateral aspect of his left ankle. The tumor was treated with total excision and adjuvant chemotherapy.Histopathologic examination of the excised tumor revealed a biphasic synovial sarcoma. There was no evidence of local recurrence or distant metastasis of the tumor at follow-up examination 24 months postoperatively.
Monophasic Synovial Sarcoma Presenting as Infantile Hemangioma: A Case Report
2020
Objective: This report describes a case of a monophasic synovial sarcoma that was initially misdiagnosed as an infantile hemangioma in a 3-month-old female infant. We also discuss the basic elements of evaluating a soft-tissue mass and important radiological and clinical features that should raise the index of suspicion for a synovial sarcoma. Summary Background Data: Synovial sarcoma is a rare pathology that is often challenging to diagnose due to its similarities with more common vascular lesions that occur in infancy. Infantile hemangioma, in particular, is common, has distinctive clinical and radiological findings, and is frequently diagnosed without histological confirmation. This increases the risk of misdiagnosis of rare tumors in infancy. Case Report: A 3-month-old female infant presented with a soft-tissue mass on the left forearm. Physical examination showed a well-defined, subcutaneous mass on the left forearm, measuring approximately 3 cm × 5 cm, firm in consistency, wit...

The incidence of synovial sarcoma is 1.548 per 1,000,000. Synovial sarcoma localized to the palmar surface should, therefore, be considered extremely rare. This report documents a 34-year-old male with a right hand mass that had been present for a few years, continuing to grow in size. The mass was located at the palm and extended from the mid-third metacarpal to involve all digits except the thumb. The mass was determined to be monophasic synovial sarcoma on histopathologic exam. Fluorescence in situ hybridization for SYT gene rearrangement was positive in 72% of cells. Resection of the mass was followed by radiation and chemotherapy. The patient had a long-term follow-up of 3.5 years with no evidence of any local recurrence of the tumor. This report increases awareness of this extremely rare malignancy—an awareness that is crucial for early diagnosis and improved survival rates. It is more common at younger ages but it can occur at any age, so it should be suspected and included i...
Primitive synovial sarcoma of suboccipital region in child
Journal of Surgical Case Reports, 2018
Synovial sarcoma (SS) most commonly affects the lower limbs of males in the third to fifth decades of life, with masses of the head and neck accounting for 3-10% of all cases, mainly as a metastatic lesion. The lack of specific symptoms and radiological features in addition to the diversity of their microscopic aspects may cause confusion in the diagnosis; hence, knowledge of the unusual locations of SSs is very important. The immunohistochemistry, and more recently the cytogenetic studies, contribute to the differential diagnosis. We report the case of a 12-year-old girl with a rare primary SS in the suboccipital region, which underwent complete surgical resection.
An unusual occurrence of synovial sarcoma in forearm: a case report
The Pan African Medical Journal, 2021
Soft tissue sarcomas are group of malignant tumours arising from extra skeletal mesenchymal tissue. Presenting a patient with swelling over the posterior aspect of left arm for 6 months, gradually increasing in size for four months and rapidly increasing in size for last 2 months and not associated with pain. Peripheral pulses felt. Ultrasound showed large solid cystic intramuscular lesion arising from triceps muscle and Trucut biopsy showed poorly differentiated malignancy. Magnetic resonance imaging (MRI) left arm impression was large lobulated solid cystic space occupying lesion in triceps muscle, possibility of neoplastic lesion. Here the patient underwent wide local excision and reconstruction procedure followed by Radiotherapy, chemotherapy and regular follow up.
Synovial sarcoma of childhood and adolescence. Report of the german CWS-81 study
Cancer, 1993
Background. Synovial sarcoma is the third most common pediatric soft tissue tumor. It requires an aggressive approach to achieve a cure. However, optimal treatment modalities adapted to disease extension and histologic variants have not been determined because there is little information about prospectively treated patients.

Purpose Synovial sarcoma (SS) is an aggressive softtissue tumor noted for late local recurrence and metastasis. This study investigates the long-term outcome of SS in patients of pediatric age and evaluates potential prognostic factors for SS. Methods We performed a retrospective review of 13 SS cases in patients younger than 20 years at the time of diagnosis who had a minimum follow-up of 10 years. The mean follow-up for living patients (n = 8) was 20.1 years (12.1-27.6) and for nonsurvivors (n = 5) 4.9 years (range: 2.6-9.3). Nine patients had unplanned excisions (69%), of which 6 (67%) were performed prior to their referral. Re-excisions were necessary in all 13 patients. The factors sex, tumor site, tumor size, tumor grade, histological subtype, fusion type, and type of treatment were evaluated for their prognostic value. Results Only 2 patients (15%) met the criteria of adequate tumor treatment. Overall, the 5-and 10-year survival rates were 77 and 61%, respectively. The mean time until a local recurrence (n = 5) was 3.2 years (range: 0.7-10.2), while there was a mean time of 2.1 years until the occurrence of late metastases (n = 5; range: 0.8-4.8). A high tumor grade and having a tumor in the trunk were adverse factors in terms of overall, local recurrence-free, and metastasis-free survival. Patients with wide resections or amputations had fewer local recurrences than patients with marginal or intralesional resections. Conclusion Inadequate primary excision of SS results in incomplete excision in the majority of cases. The tumor site, size, and histological grade should be considered when determining a risk-adapted treatment for SS, and wide surgical excision is the surgical intervention of choice. While local recurrence and late metastases appear to occur after a shorter time period in pediatric patients than in adults, in view of the tendency for late recurrence and metastasis with SS, follow-up should be at least 10 years.
Biphasic synovial sarcoma in a 19-year-old pregnant woman: a case report
Romanian journal of morphology and embryology = Revue roumaine de morphologie et embryologie, 2015
Synovial sarcoma is a rare malignant tumor of mesenchymal multipotent cells. We hereby present a case of synovial sarcoma of the upper left thigh. A 19-year-old patient was referred to our clinic by another hospital in Bucharest, Romania, for a soft tissue mass in the left upper thigh. Local examination of the left thigh revealed a 15÷13 cm, ovoid, painful upon touch, soft tissue mass occupying the proximal-medial aspect of the thigh. Bilateral inguinal nodes' enlargement was noticed. Upon suspecting regional node involvement, the surgical team decided to perform left limb amputation due to tumor size and the proximity to major arterial and nervous trunks as well as the femoral shaft, making curative surgery and 'free of disease' resection margins improbable. The patient refused the operation. The surgical team (plastic surgeon, orthopedic surgeon) decided to attempt limb-sparing surgery. After tumor resection, free-of-disease surgical margins were achieved. The patholog...
