Patient presents with concerning symptoms suggestive of sarcoma.  Chief complaint includes [specific chief complaint, e.g., a palpable mass, pain, swelling, limited range of motion] located in [specific location, e.g., the proximal thigh, abdomen, retroperitoneum].  On physical examination, a [description of the mass: size, consistency, mobility, tenderness] was noted.  The patient reports [duration of symptoms, associated symptoms such as weight loss, fatigue, fever].  Differential diagnosis includes soft tissue sarcoma, bone sarcoma, Ewing sarcoma, chondrosarcoma, osteosarcoma, gastrointestinal stromal tumor (GIST), synovial sarcoma, and other malignant neoplasms.  Imaging studies including [specify imaging: MRI, CT scan, X-ray, bone scan] of the [affected area] were ordered to evaluate the lesion and assess for metastatic disease.  Biopsy of the suspicious lesion is scheduled for histopathological diagnosis and grading.  Preliminary assessment suggests a possible diagnosis of sarcoma.  Further workup including blood tests (complete blood count, comprehensive metabolic panel) and possibly PET scan will be performed depending on biopsy results.  Treatment plan will be determined based on the final diagnosis, tumor grade, stage, and patient's overall health status.  Potential treatment options include surgical resection, chemotherapy, radiation therapy, targeted therapy, or a combination thereof.  Patient education provided regarding sarcoma diagnosis, prognosis, treatment options, and potential side effects.  Referral to oncology and orthopedics (if applicable) has been made for consultation and co-management.  Follow-up appointment scheduled to discuss biopsy results and formulate a definitive treatment plan.  ICD-10 code [appropriate ICD-10 code based on location and type, e.g., C49.0 for malignant neoplasm of upper limb, connective and soft tissue] is provisionally assigned pending confirmatory diagnosis.
