Primary extraskeletal mesenchymal chondrosarcoma of the vulva
A 52-year-old, postmenopausal woman visited our clinic with a complaint of a mass of the vulva. She had noticed a small but growing mass on her left vulva which had been palpated 2 months earlier. On physical examination, a globular, movable mass measuring about 2 cm in diameter was palpated in the left major labium. The mass was excised with a 2 cm resection margin. The pathological report confirmed a 4×3.8×2 cm sized EMC of the vulva revealing no microscopic lesions on the resection margins. Immunohistochemistry was performed on the tumor to analyze the expression of vimentin, S-100 protein, desmin, Pan-CK, smooth muscle actin, and EMA. She recovered from surgery without any complications. Bone scans and chest radiographs for disease staging were negative. After twenty four-month of following the initial diagnosis, the patient remains without evidence of any recurrent disease as assessed by pelvic MRI and chest radiographs.
