“…However, sacroiliac joint involvement is not exclusive to spondyloarthropathies (SpA), and there are several other conditions which may mimic sacroiliitis. Several such mimickers have been reported, including brucellosis, gluteal abscess, pyogenic sacroiliitis, tuberculosis, Ewing sarcoma, epithelioid sarcoma, osteoid osteoma, sarcoidosis, metastatic adenocarcinoma, hyperparathyroidism, osteomalacia, osteitis condensans ilii, and sacral insufficiency fracture [1][2][3][4][5][6][7][8][9][10][11]. Herein, a case of thyroid cancer who referred to a rheumatology clinic due to hip pain is reported.…”

Sacroiliac joint involvement is not specific to seronegative spondyloarthropathies (SpA). There are some rare reports of conditions which mimic sacroiliitis. This paper reports a case of follicular thyroid carcinoma in a patient who had been referred to a rheumatology clinic with hip pain. Sacroiliac joint involvement was her presenting feature before she was correctly diagnosed. The patient was a female, 63 years of age, who referred to a rheumatologist because of unilateral hip pain. Patrick's test on her right side was positive, and the range of motion of her right hip was restricted. Imaging studies included conventional hip radiography and magnetic resonance imaging (MRI) revealed sacroiliitis with surrounding destructive lesion. In review of systems and physical examination, a thyroid nodule was found. Computed tomography (CT)-guided needle biopsy of her hip and fine needle aspiration (FNA) of the thyroid nodule established follicular thyroid carcinoma. In approach to sacroiliitis, rare differential diagnoses (besides SpA) and mimickers of sacroiliitis such as neoplastic lesions should also be considered to avoid misdiagnosis.

“…Despite its very wide range of soft tissue locations including the scalp, perineum and extremities , ES originating from other organ site is extremely rare and has been reported only in the bone (2 cases) and joint (4 cases) . With regard to the intra‐articular cases, however, their radiologic and histologic description and documentation of the intra‐articular origin of the tumor have been either imprecise or incomplete.…”

Primary synovial epithelioid sarcoma of the knee: distinctly unusual location leading to its confusion with pigmented villonodular synovitis

Epithelioid sarcoma (ES) is a rare malignant soft tissue tumor occurring in the distal extremities of young adults and is characterized histologically by nodules of epithelioid cells showing central necrosis. Intra-articular ES is extremely rare; only four cases have been reported, but their radiologic and histologic documentation of intra-articular origin have been imprecise. We report the first radiologically and histologically well-documented case of primary synovial ES. A 59-year-old woman presented with pain followed by swelling of her right knee for 6 months. MRI revealed an entirely intra-articular nodular synovial mass in the lateral part of the right knee joint in a background of diffusely thickened synovium. Synovectomy was performed under the clinical impression of pigmented villonodular synovitis (PVNS), a diagnosis erroneously confirmed by the reporting pathologist. The tumor rapidly recurred 3 months afterward and the diagnosis of primary synovial ES was made. Despite above-knee amputation, the tumor continued to spread proximally to the retroperitoneum. She developed multiple lung metastases and died 20 months after initial presentation. The nodular aggregates of tumor cells with central necrosis resulted in diffuse polypoid synovial thickening mimicking tuberculous synovitis and PVNS. The tumor cells showed positive staining for EMA, CK19, CD34, and complete loss of INI1 staining, establishing the diagnosis of primary synovial ES. The ES spread from the synovium to and along the joint capsule, and then extra-articularly into the soft tissue surrounding the knee joint, with lymphovascular permeation. Such pattern of spread calls for radical surgical excision as the treatment of choice.

Epithelioid Sarcoma in the Cervical Spine: A Case Report

Epithelioid sarcoma is a rare and highly malignant soft tissue neoplasm that most commonly occurs in the long bones. This uncommon tumor has a poor clinical outcome, and the modality of its treatment has not yet been fully established. The authors report an extremely rare presentation of epithelioid sarcoma in the cervical spine, along with its clinical progression, imaging, and pathology. The patient underwent three surgical procedures and adjuvant radiochemical management. He survived for 25 months with a good general condition and adapted well to his social activity. Systemic metastasis was not found, but the patient died of respiratory failure due to direct tracheal invasion of the tumor.
