Incidence of Sarcomatoid Carcinoma 5-10% of all patients with thymic carcinoma. Carcinoma Sarcomatoid is a highly progressive tumor, most patients will die after 3 years of diagnosis despite aggressive multimodality therapy.Case Description: A 47-year-old woman with chest pain, shortness of breath, coughing, weight loss, enlarging lump in the neck and chest was felt for 1 month. Physical and supporting examination showed anterior superior mediastinal tumors and soft mass tissue in the right region of the Colli. Based on the Transthoracal FNAB Guiding ultrasound and FNAB the anterior colli region concluded that Thymoma, thyroid oncocytic adenoma and Nodular colloid goiter with azkanasy cell proliferation. The patient had Partial Sternotomy (Hemiclamshell), thymectomy with the final diagnosis of Sarcomatoid Carcinoma. Discussion: Sarcomatoid carcinoma is a type of thymic carcinoma that has both malignant epithelium (carcinomatous) and spindle cells (sarcomatous/sarcomatoid), generally with a transition between the two. This case was interesting because of the rare occurrence of Sarcomatoid Carcinoma plus the large size of tumor mass in this patient.Â
