As they often show similar clinical and radiological findings, histology is the definitive diagnostic method and it is crucial that the surgical pathology report contains accurate, useful information for management and prognostication. Hepatic Pathology. Accordingly, the presence of SATB2 in the rhabdoid-appearing cells in our specimen helps to confirm the diagnosis of an osteosarcoma with prominent rhabdoid features. Digital cases Case 115: Chondroblastic osteosarcoma of the calcaneum. However, SATB2 positivity is not specific for osteosarcoma and cannot differentiate it from other primary bone sarcomas, which has been well documented by Davis and Horvai [ 12 ]. 7c, d). SATB2, a marker of osteoblastic differentiation was positive only in the osteosarcomatous component, whereas leiomyosarcoma areas were negative (Fig. The well-established multimodality treatment incorporates systemic chemotherapy with local control in the form of surgery, with or without radiation. A final diagnosis of an osteoblastic osteosarcoma was made. SATB2 showed 100% sensitivity (10/10) and 60% (6/10) specificity in discriminating classic osteosarcoma from osteosarcoma mimics. What is the broad type of cancer: carcinoma (broadly including germ cell tumor), melanoma, lymphoma or sarcoma? The presence of ubiquitous rhabdoid cells and an osteosarcomatous appearance on pathology in conjunction with SATB2 positivity is why we have identified this a unique entity. SATB2 was negative in all soft tissue tumours with prominent sclerotic stromal collagen. pp. Retroperitoneal sarcomas comprise approximately 10% of all soft tissue sarcomas. By definition, they are located in the soft tissues without primary bone or periosteal involvement. Symptoms. Though any soft tissue sarcoma histologic types may arise in the retroperitoneal space, liposarcoma (especially well-differentiated and dedifferentiated types) and leiomyosarcoma do so most commonly. Osteosarcoma is the second most common primary malignant tumor of bone. Stronger-intensity staining was observed in osteosarcoma (P < 0.0001). Small round cell osteosarcoma is a very rare type of osteosarcoma, histologically mimicking other small round cell malignancies of bone, most notably Ewing sarcoma. There are approximately 600 to 700 new cases of osteosarcoma … These tumors cannot be diagnosed without the help of radiology. Common reported sites of involvement include limbs, retroperitoneum, chest wall and buttocks. 1–4 There are two practical goals: One is to confirm a tumor diagnosis by excluding morphologic mimickers or to identify the most reasonable tissue or organ of origin in cases of metastatic carcinoma of unknown primary. 13, Pages 3261: Is It Time to Call Time on Bone Marrow Biopsy for Staging Ewing Sarcoma (ES)?
