Synovial sarcoma is a rare soft tissue sarcoma that commonly involves the lower extremities and occurs predominantly in young adults. It very rarely occurs in the head and neck region and carries a poor prognosis. The tumor demonstrates both a loco-regional and a systemic pattern of spread that makes management challenging. Combined modality therapy of this aggressive tumor yields better results. Herein, we described a 58 years old lady presented with left parapharyngeal synovial sarcoma. This is to demonstrate the aggressiveness of the disease despite complete surgical excision followed by post operative radiotherapy. Local regional control was difficult and recurrence of disease was seen in this particular patient.

Synovial sarcoma (SS) is a malignant soft tissue tumour of uncertain histogenesis which is defined by the translocation t(X;18) that produces the fusion oncogenes SYT-SSX. The emergence of transducer-like enhancer of split 1 (TLE1) as a new immunohistochemical (IHC) marker for SS has offered an alternative to pathologists in differentiating SS from other histological mimics, especially in the setting of limited molecular facilities. We investigated the utility of IHC TLE1 expression against histomorphological features and other IHC markers in SS and non-SS tumours. Twenty-six cases of histologically diagnosed SS and 7 non-SS (for which SS was in the differential diagnosis) were subjected to TLE1 IHC staining, which was graded from 0 to 3+. Of the 26 SS cases, 12 each were biphasic and monophasic types and 2 were poorly-differentiated. TLE1 was expressed in 22/26 (84.6%) SS cases, of which 11/12 (91.7%) were biphasic, 10/12 (83.3%) monophasic and 1/2 (50%) poorly-differentiated tumours. Two of 7 (28.6%) non-SS cases were positive for TLE1. Immunopositivity of SS and non-SS cases for EMA were 20/26 (76.9%) and 2/7 (28.6%) respectively and for CK7 were 7/26 (26.9%) and 0/7 (0%) respectively. All cases were negative for CD34. Consistent histomorphological features for SS included mild nuclear pleomorphism, alternating tumour cellularity, fascicular growth pattern and thick ropy stromal collagen. In conclusion, TLE1 is not a stand-alone diagnostic IHC marker for SS. However, in the absence of molecular studies, it can contribute added diagnostic value in combination with morphological evaluation and other IHC markers such as EMA and CD34.

PMID: 20507738

Synovial sarcoma is a rare soft tissue sarcoma of the head and neck region involving the parapharyngeal space. The diagnosis of synovial sarcoma can be very challenging to the pathologists. We present a rare case of parapharyngeal synovial sarcoma in a young female patient who had a two-month history of left cervical intumescent mass at level II. The fine needle aspiration cytology of the mass was proved inconclusive. Transcervical excision of the mass was performed and the first case of parapharyngeal sarcoma was identified in our center by fluorescence in situ hybridization (FISH) technique. Repeat imaging revealed residual tumor. The patient successfully underwent a second excision of the residual tumor and received adjuvant radiotherapy.

Synovial sarcoma of the extremities is an uncommon type of soft tissue sarcoma occuring predominantly in young adults at the para-articular regions. We present a series of 10 patients with an average age of 44 years and include a follow-up of 39 months. Eight patients had a surgical procedure for a mistaken benign lesion. In contrast to other soft tissue sarcomas, the swellings were associated with pain and most were fixed to the underlying structures. Five patients had a local reccurence after many years, stressing the necessity for close and long-term follow-up in these patients.

Synovial sarcomas are deep-seated, genetically distinct, malignant neoplasms seen in young adults, with a male preponderance. They have unusual clinical and pathological presentation and mimic many other sarcomas and carcinomas, making the diagnosis quite challenging. Although four variants are identified, occurrence in the hand is extremely rare and leads to significant morbidity. There is a high incidence of local recurrence and distant metastasis within the first 2 years. We report the case of an elderly woman with monophasic spindle cell synovial sarcoma who presented with painless swelling in her palm and underwent local excision of the neoplasm. At 2-year follow-up, she remains totally asymptomatic with normal function of the hand. We also attempt to give an overview about monophasic spindle cell synovial sarcoma with the differentials, which would help surgeons in prompt diagnosis and appropriate management.

Thoracic sarcoma case series in Hospital Kuala Lumpur, Malaysia

Yurkdes AS, Narasimman S

Med J Malaysia, 2019 Jun;74(3):237-239.

PMID: 31256182

Thoracic sarcomas (TS) are rare neoplasms that may present with non-specific pulmonary symptoms. Chest radiographs and computed tomography of the thorax are the investigations of choice, while pre-operative minimally invasive biopsies may not be entirely helpful with the diagnosis. The commonly identified variants of thoracic sarcomas include liposarcomas, leiomyosarcomas and synovial sarcomas. Complete excision of the tumour with clear margins remain the sole definite form of management and there is limited role with adjuvant chemotherapy and radiotherapy. In the present case series, we explore our experience with three patients who presented with TS and the management decisions that was made.

Head and neck synovial sarcoma is rare. We report the case of a 71-year-old man who presented with progressive dysphagia, odynophagia, shortness of breath on exertion and hoarseness of voice. Nasendoscopy revealed a smooth, non-fungating, non-ulcerative mass arising from the left lateral pharyngeal wall. CT showed a well-defined, heterogenous enhancing lesion arising from the left pyriform fossa. Initial biopsy taken was inconclusive and patient underwent a transcervical complete excision of the tumour, where histopathological analysis confirmed the diagnosis of monophasic synovial sarcoma of the left pyriform fossa. This patient also received adjuvant radiotherapy postoperatively and remained disease free 1 year after completion of treatment.

Sarcomas usually frequented in the head and neck region of young adults. Trachea is a rare site, and due to scarce clinical data, its clinical outcome is unclear. We reported a case of 60-year old patient presented with progressive worsening shortness of breath, cough, and progressive worsening dysphagia. Computer tomography scan revealed extensive 2 lobulated soft tissue lesions within and surrounding the trachea at the T4 level. Rigid bronchoscopy with mass cryo-debulking was performed and ultimately synovial sarcoma was diagnosed. Shortness of breath was com- pletely relieved post-procedure.

We report a case of 29-year-old female who presented with right heel pain that worsened over a period of two years. The onset of pain was followed by swelling at the medial aspect of right ankle. She was initially treated for plantar fasciitis with multiple steroid injections over the heel. Subsequent MRI revealed a well-defined heterogeneous lesion in continuity with the medial plantar nerve. Excision biopsy was performed and histopathological evaluation revealed monophasic synovial sarcoma. The patient subsequently underwent wide resection and free tissue transfer followed by radiotherapy and chemotherapy. This case highlights an unusual site and presentation of synovial sarcoma which led to delayed diagnosis and treatment.

Fulltext Exploring Two Protocols of FISH Using Cytocell SYT-SSX Probe on Formalin Fixed Paraffin Embedded Tissue Sections

Yajid AI, Mohd Nafi SN, Salehan NA, Tuan Sharif SE

Asian Pac J Cancer Prev, 2020 May 01;21(5):1241-1245.

PMID: 32458628 DOI: 10.31557/APJCP.2020.21.5.1241

BACKGROUND: Chromosomal translocation t(X;18)(p11.2;q11.2) is the cytogenetic hallmark of synovial sarcoma and have been identified as an alternative diagnostic strategy in differentiating synovial sarcoma from other histologic mimics. This study was carried out to test the efficacy of two FISH protocols using the SYT-SSX break apart probe from Cytocell.

METHODOLOGY: Representative paraffin blocks of synovial sarcoma were utilized in this study. FISH study was performed on formalin-fixed paraffin embedded tissue sections using the SYT-SSX break apart probe from Cytocell, to detect two form of SYT-SSX transcript, SYT-SSX1 and SYT-SSX2. FISH protocol, including the hybridization was done following two different protocols, Cytocell FISH protocol and Optimized Dako FISH protocol.

RESULTS: Tissue samples subjected to FISH using Cytocell FISH protocol showed the absence of signal corresponding to the probe used. Utilizing Optimized Dako FISH protocol, the two signals (red and green) corresponding to the break-apart probes was detected. These findings suggested that Optimised Dako FISH protocol is more suited for use with the tested probe on paraffin embedded tissues in comparison to Cytocell FISH protocol.

CONCLUSION: Optimised Dako FISH protocol was noted to be more suited for detecting SYT-SSX FISH signals on paraffin embedded tissues in comparison to Cytocell FISH protocol.

Mycetoma or synovial sarcoma? A case report with review of the literature

Jimenez AL, Salvo NL

J Foot Ankle Surg, 2011 Sep-Oct;50(5):569-76.

Mycetoma, also commonly referred to as Madura foot, is statistically rare in the United States. However, it is endemic to other parts of the world. It is a pseudotumor characterized by a triad of tumefaction, draining sinuses, and grains. Two types exist, with each caused by different groups of organisms that require different treatment approaches. Therefore, the exact diagnosis and culture of the organism is vital to successful treatment outcomes. Synovial sarcoma, in contrast, is a malignancy much more commonly seen in the United States. It is characterized by a well-circumscribed, often palpable, mass that is usually well delineated on magnetic resonance imaging. It has characteristic histologic and genetic features that help distinguish it from other soft tissue masses. We present a case of a soft tissue mass diagnosed in the United States. The patient had several clinical and radiographic features of synovial sarcoma but the histologic outcome was mycetoma. The case is followed by a review of the published data.

PMID: 32166036 DOI: 10.1002/rcr2.547

Primary pleural synovial sarcoma (PPSS) is an extremely rare malignancy without a known cause. The diagnosis is made after excluding metastasis from an extra-thoracic sarcoma. We report a case of a 67-year-old gentleman who presented with an incidental finding of a left lung mass on a routine chest X-ray. A computed tomography (CT) of the thorax and whole-body positron emission tomography (PET)-CT was done confirming a left lung mass with no other extra-thoracic involvement. A lobectomy was performed with a diagnostic and therapeutic intent. The histopathological examination and immunohistochemistry study revealed a pleural-based tumour with features suggestive of synovial sarcoma. Subsequently, he underwent post-operative radiotherapy. However, three months later, he developed an endobronchial recurrence, complicated by post-obstructive pneumonia resulting in his demise. This case highlights a rare form of malignancy with a rare site of recurrence.
