Neck synovial sarcoma: case presentation

Abstract

Head and neck synovial sarcoma (HNSS) is a rare tumor with a few case reports or case series being published in the literature. We present the case of a 68-year-old patient admitted to our department for management of a palpable neck mass. After initial investigation and due to major problems of differential diagnosis, there was performed a wide excision of the tumor. Histopathology examination revealed an HNSS.

Node‐by‐node diagnosis for multiple ipsilateral nodules by segmental adrenal venous sampling in primary aldosteronism

“…Subclinical Cushing syndrome is caused by cortisol coproduction from APA or another CPA in 10%–20% patients with PA 14,33,34 . In previous reports, four and two out of 15 patients with multiple nodules had complications of subclinical Cushing syndrome or Cushing syndrome, respectively 8–17 . In the current case, one out of 11 patients had PCC ≥ 138 pmol/L (5 µg/dl) after 1 mg DST, and another four patients had PCC ≥ 50 nmol/L, Furthermore, sAVS can at times diagnose CPA based on the suppression and non‐suppression of the normal adrenal cortex and CPA, respectively, 4 but often it cannot.…”

“…It is not recommended for unilateral PA based on cAVS results, since it could leave a micro‐PA lesions on the surgical side, 8 but comparable outcomes have been reported for total or partial adrenalectomy following sAVS 5 . Some patients with PA have multiple adenomas on the surgical side 8–17 . If all of these nodules are functional APAs or cortisol‐producing adenomas (CPAs), total adrenalectomy is recommended.…”

“…5 Some patients with PA have multiple adenomas on the surgical side. [8][9][10][11][12][13][14][15][16][17] If all of these nodules are functional APAs or cortisol-producing adenomas (CPAs), total adrenalectomy is recommended. However, if only one of those nodules is APA, and the others are nonfunctioning nodules, partial adrenalectomy 5 or less invasive radiofrequency ablation [18][19][20] could be an option.…”

Anterior Endoscopy Combining with Modified Total En Block Spondylectomy for Synovial Sarcoma in Thoracic Paraspine Causing Neurological Deficits: Case Report and Literature Review

“…Evident patchy calcification at the edge of the vertebral body and spinal cord compression was observed 6 . MRI is more sensitive and accurate than CT and plain films for diagnosis and staging purposes.…”

“…Evident patchy calcification at the edge of the vertebral body and spinal cord compression was observed. 6 MRI is more sensitive and accurate than CT and plain films for diagnosis and staging purposes. A total of 40% of synovial sarcoma revealed hyperintense signal on T1WI and intermediate signal on T2WI, which may be related to bleeding.…”
