Superficial CD34 Positive Fibroblastic Tumour, A Mesenchymal Tumour with Borderline Malignant Potential: A New Entity

Glioneuronal-mesenchymal tumour with malignant transformation.

We report a case of a 10-year-old girl with a tumour of the right temporoparietal region of the brain. The tumour consisted of three morphologically distinct portions: a well-differentiated one containing a mixture of a ganglioglioma with adipocytic-like cells and focal chondroid metaplasia, a separate island with neurocytic differentiation, and the malignant one, which exhibited an organoid pa...

CD34-positive superficial myxofibrosarcoma: a potential diagnostic pitfall.

BACKGROUND Myxofibrosarcoma (MFS) arises most commonly in the proximal extremities of the elderly, where it may involve subcutaneous and dermal tissues and masquerade as benign entities in limited biopsy samples. We encountered such a case, in which positivity for CD34 and morphologic features were initially wrongly interpreted as a 'low-fat/fat-free' spindle cell/pleomorphic lipoma. Case serie...

Soft tissue giant cell tumour of low malignant potential: a rare tumour at a rare site.

"Soft tissue giant cell tumour of low malignant potential" is considered as the soft tissue counterpart of osteoclastoma of the bone. It is a primary soft tissue tumour which is classified under the category of fibrohistiocytic tumours of intermediate malignancy.Seventy percent of the tumours involve the extremities and only about seven percent of them arise in head and neck region. They are co...

Soft Tissue Giant Cell Tumour of Low Malignant Potential: A Rare Tumour at a Rare Site

Sinonasal Teratocarcinosarcoma- A Rare Tumour not so Rarely Misdiagnosed

Sinonasal teratocarcinosarcoma (STCS) is a rare, morphologically heterogeneous and highly aggressive tumour of ambiguous origin. It is characterized by the presence of benign and malignant epithelial, mesenchymal and neuroectodermal components. Because of their rarity and heterogeneity, these lesions are often misdiagnosed, leading to management difficulties. Adequate sampling with a high index...
