Abstract : Sarcomas are rare malignant tumors of mesenchymal cells which occur primarily in the head and neck region in the adults. Occurrence of this tumour in the tongue has very rarely been reported and is associated usually with recurrence and metastasis, than complete and permanent cure after the first surgical intervention. We report here an unusual case of spindle cell sarcoma arising from the tongue in a 25 year-old male who presented with an ulcerated mass on the anterior right margin of the tongue.
Abstract : Pigmented villonodular synovitis (PVNS) of the knee is a benign but locally aggressive disease of synovial proliferation that occurs in localized nodular and diffuse villous growth patterns. Although inflammatory and neoplastic causes have been hypothesized, etiology remains unknown. PVNS usually presents as unilateral knee pain and swelling and mimics other knee ailments. Radiographs are often unremarkable, whereas magnetic resonance imaging may show characteristic intra-articular masses with signal dropout on T2-weighted sequences. The condition is surgically treated with open or arthroscopic total or partial synovectomy. High recurrence rates are associated with all treatments of diffuse PVNS. Intra-articular radioisotope injection and external beam radiation may be beneficial adjuvant therapy for extensive diffuse and recurrent PVNS of the knee. We report a rare case of pigmented villonodular synovitis in a 56-year-old woman, who presented with a painful mass in the posterior part of the left knee.
