Fibrohistiocytic cells are visible in the underlying dermis.
Cytologic atypia, giant cells in the fibrohistiocytic type and an appearance of a prominent storiform pattern with an SFT may bring malignant fibrous histiocytoma to mind.
The term histoid derives by the histological finding of the dermal infiltrate composed by a predominance of spindle shaped cells or polygonal cells that may resemble a fibrohistiocytic tumor (dermatofibroma).
However, there are also numerous histopathologic variants, including spindle cell, atypical or pleomorphic, sclerotic, glandular, fibrohistiocytic, and chondroid lipomas (4), myxolipomas (5), fibrolipomas, angiolipomas, angiomyolipomas, and infiltrating angiolipomas; these are categorized according to their content of fat, muscle, blood vessel, connective tissue, or other structures (3).
Differential diagnosis of GCT-ST includes soft tissue mesenchymal tumour which are rich in giant cell, villonodular sinuvitis, cellular dermatofibroma, atypical fibroxanthoma, plexiform fibrohistiocytic tumour, malignant fibrous histiocytoma, leiomyosarcoma, extraskeletal osteosarcoma and epithelioid sarcoma.
3,7] Today it is reported that the cells that MFHs originate from fibroblasts or undifferentiated mesenchymal cells; the available histiocytes are reactive and using the term fibrohistiocytic would be definitive as well.
Myofibroblastic and fibrohistiocytic tumors, pleomorphic sarcoma, liposarcoma, leiomyosarcoma, rhabdomyomas and rhabdomyosarcomas, vascular tumors, tumors of synovial tissue, nerves, melanocytes, cartilage and osseous tissue, and other miscellaneous tumor types are covered, with most systemic categories divided into chapters on benign, intermediate, and malignant tumors.
Most common diagnosis were GIST and Undifferentiated sarcoma not otherwise specified 7 cases (14%) each, followed by Ewings sarcoma /PNET were 6 cases (12%), Synovial sarcoma were 5 cases (10%), 4 cases (8%) of Liposarcoma & Rhabdomyosarcoma each, 3 cases (6%) of Leiomyosarcoma & Fibrohistiocytic sarcoma each, 2 cases (4%) of Dermatofibrosarcoma protuberance & Malignant peripheral nerve sheath tumour each, Other cases like Neuroblastoma, Extraskeletal Myxoid Chondrosarcoma also identified.
Dermatofibrosarcoma protuberans (DFSP) is an uncommon, fibrohistiocytic tumour known to be locally invasive and with very low incidence of distant metastasis (1).
In the histopathological examination, revealed an ill-defined dermal proliferation of elongated fibrohistiocytic cells and sometimes of storiform pattern.
