“…Unplanned total excisions of STSs are inadequate, with a local failure rate as high as 49%, despite multimodality therapy. It is important to distinguish STSs from BPNTs preoperatively, as the former are often mistaken for the latter and may be resected with inadequate margins …”

“…Preoperative diagnosis of SS is challenging because of its nonspecific symptomatology, low clinical morbidity, lack of specific radiologic features, and physicians’ unfamiliarity. The most frequent preoperative diagnosis is neurogenic tumors and a recent study of peripheral SS suggests that pain, short symptom duration, peritumoral edema without a definite target sign on MR images should evoke SS [7] .…”

HighlightsSynovial sarcoma (SS) is an extremely rare head and neck malignancy in the pediatric population.Preoperative diagnosis of SS is challenging because of its nonspecific symptomatology, low clinical morbidity at presentation, lack of specific radiologic features, and physicians unfamiliarity.We present this case to emphasize the correlation between histopathology diagnosis and clinical judgment to perform optimal treatment (surgical, chemo and/or radiotherapy) with preservation of pharyngeo-laryngeal function in the pediatric population.

“…For radiological characteristics, compartmental status [ 14 ], presence of peritumoral edema [ 15 , 16 ], and the tumor border [ 7 ] were investigated using preoperative MRI scans. Spin-echo T1-weighted sequences, fast spine-echo T2-weighted sequences with fat suppression, and gadolinium-enhanced T1-weighted sequences with fat suppression were available in all MRIs.…”

“…There were 91 intracompartmental (63%) and 53 extracompartmental tumors (37%). Peritumoral edema was defined as diffuse regions of increased T2-weighted signal intensity surrounding the tumor [ 15 , 16 ]. Of the 144 tumors, 39 tumors (27%) showed peritumoral edema.…”

Soft tissue sarcoma (STS) with an infiltrative histologic growth pattern, when compared to STS with an expansile pattern, may pose difficulties in local control. Preoperative assessment of the presence of infiltrative histologic growth pattern would be helpful in deciding treatment strategies. A review of 144 patients who underwent surgery for extremity STS was performed. Microscopically, the histologic growth pattern was defined as infiltrative if the penetration of the tumor cells into the surrounding tissue was observed. Possible clinicopathologic factors that might be associated with infiltrative histologic growth pattern were investigated with regard to patient demographics, tumor characteristics, and MRI findings. Of the 144 tumors, 71 (49%) showed infiltrative histologic growth pattern. On multivariate analysis, histological subtypes other than liposarcoma (OR = 4.57, p = 0.02) and infiltrative border on MRI (OR = 2.48, p = 0.01) were independent factors associated with infiltrative histologic growth pattern. Predictive index based on these two factors showed a significant improved accuracy (ROC-AUC = 0.647) for predicting infiltrative histologic growth pattern compared to either factor alone. Our data suggests that liposarcoma histology and tumor border on MRI can predict histologic growth pattern in extremity STS.
