Primary cerebral intra-axial epithelioid angiosarcoma is an extremely rare malignancy. To the best of our knowledge we describe the first case of epithelioid angiosarcoma arisen in the septum pellucidum of a 54-years-old man. Albeit extremely rare, this neoplasia is a potential source of misdiagnosis for other aggressive malignant tumors, and it should be taken into consideration.

The cutaneous epithelioid angiomatous nodule is an uncommon benign vascular proliferation that has only recently been described. Clinically, it usually presents as a solitary, fast-growing, small reddish papulous or nodular lesion on the trunk or limbs of adults. Histopathologic study reveals a proliferation of epithelioid cells and predominantly solid, well delimited, unilobular growth in the ...

Eight cases of uveal malignant melanoma were studied with the electron microscope with the purpose of comparing the ultrastructural features of the three basic cell types (spindle A, spindle B, and epithelioid) originally described by Callender under the light microscope. Five of the eight tumors were of pure cell type, and three were mixed. This was undertaken because of earlier diverse opinio...

INTRODUCTION The rare variant of renal epithelioid/pleomorphic angiomyolipoma has been reported in approximately 120 cases. One of the most important characteristics to differentiate these tumors from other renal cell neoplasms is their typical reactivity to premelanosome antigens. If such a tumor does not stain for HMB-45 or Melan-A, a specific diagnosis of epithelioid pleomorphic angiomyolipo...

BACKGROUND Extrapleural Solitary Fibrous tumors (SFTs) have been increasingly reported. The retroperitoneum, deep soft tissues of proximal extremities, abdominal cavity, trunk, head and neck are the most common extraserosal locations reported. Microscopically they show a wide range of morphological features, and so the differential diagnosis is extensive. Immunohistochemically, they commonly ex...

STUDY DESIGN This case report illustrates a patient presenting with sciatica and diagnosed with epithelioid sarcoma involving the spine. OBJECTIVES The treatment of this patient involved multiple mass resections and decompressions of the spinal canal. Radio- and chemotherapy were applied once a clear diagnosis was obtained. SUMMARY OF BACKGROUND DATA Epithelioid sarcoma is a rare tumor main...

Epithelioid sarcoma is an uncommon kind of that often affects young individuals and has a preference for distal upper extremity; forearm hand. This usually begins as slow-growing, painless tumor. It can also be seen multiple tumours. Lymphatic channels are the primary routes dissemination disease’s recurrence spread. Using polygonal cells, biopsy preferred technique diagnosis. Treatment primari...

Angiomyolipomas (AMLs) are benign mesenchymal tumors seen in kidneys in association with tuberous sclerosis. They are uncommon in liver. Angiomyolipomas of liver show great histological diversity and various types and patterns are described. Among them, epithelioid and inflammatory angiomyolipomas are rare. We report a case of epithelioid angiomyolipoma of Liver with an inflammatory component.
