Epithelioid Angiosarcoma of Bone: A Neoplasm with Potential Pitfalls in Diagnosis
نویسندگان
چکیده
Angiosarcoma of bone is an exceedingly rare primary bone malignancy that can present as an aggressive osteolytic lesion. This subset can radiologically mimic non-vascular neoplasms and impose serious challenges in reaching the correct diagnosis. Meanwhile histological diagnosis can be extremely challenging too, as the pathological features often resemble that of aneurysmal bone cysts. We present an unusual case of a 22-year-old woman who presented with a rapidly growing humeral tumor of 8 months’ duration. The case of intraosseous angiosarcoma presented as a diagnostic dilemma and the relevant radiological and pathologic findings were discussed. We describe the clinical, radiological and pathological features of this unique case, and review the literature concerning Angiosarcoma of bone. Our case highlights the diagnostic difficulties for such very rare tumours and clinico-pathological correlation is of paramount importance to differential diagnosis.

AIMS AND BACKGROUND Epithelioid angiosarcoma is a rare histopathologic variant of angiosarcoma characterized by an epithelioid morphology. This subset can histologically mimic non-vascular neoplasms and impose serious challenges in reaching a correct diagnosis, especially in the context of limited tissue sampling (e.g., needle core biopsy). To improve recognition of epithelioid angiosarcoma - a...
متن کاملEpithelioid Angiosarcoma in Femur: A Case Presentation
Primary malignant vascular tumors which constitute less than 1% of the primary bone tumors are very rarely encountered. Epithelioid angiosarcoma is a very uncommon subtype of angiosarcomas presenting with an epithelioid phenotype and mimicking carcinomas clinically. These tumors select mostly extra-skeletal locations but rarely bones as their medium. A 31-year-old male patient applied to our cl...

Bone marrow is an exceptionally uncommon site of metastatic dissemination in angiosarcoma (AS) as only single case reports have been published so far. We report a case of a 72-year-old male with epithelioid angiosarcoma of the liver who subsequently developed erythroblastic anemia. The trephine bone marrow biopsy revealed total replacement of the normal hematopoiesis by diffuse infiltrate of AS...

BACKGROUND Epithelioid angiosarcoma is a rare variant of angiosarcoma, and is characterized by an epithelioid morphologic appearance that mimics carcinoma. These tumors usually arise in extraskeletal sites; origination in bone is rare. CASE PRESENTATION A 69-year-old woman presented with right knee pain. Plain radiographs and magnetic resonance imaging showed an osteolytic lesion with a large...
متن کاملMulticentric epithelioid angiosarcoma of bone.
Bone epithelioid angiosarcoma is rare and generally shows positive immunostaining for epithelial markers. Multicentric bone epithelioid angiosarcoma is easily misdiagnosed as carcinoma, including metastatic carcinoma, multiple myeloma, and multiple lymphoma of bone. This article describes a case of multicentric bone epithelioid angiosarcoma. The patient was first misdiagnosed as having metastat...
