Malignant fibrous histiocytoma (MFH) is an undifferentiated high-grade pleomorphic sarcoma and is considered the most common primary soft tissue sarcoma in adults. MFH is known to arise in the trunk, extremities and retroperitoneum although it can arise anywhere in the body.MFH of the skin is uncommon and even less frequent is the involvement of the scalp, especially with skull invasion.

Multinucleated giant cells (MGCs) are a prominent histological feature of various mesenchymal neoplasms and are often considered a criterion of malignancy. Mesenchymal neoplasms with MGCs for which the cell lineage is unclear generally are referred to as giant cell sarcomas. Here we characterize the gross, histologic, and immunohistochemical features of 90 giant cell sarcomas in domestic pet rabbits. Read More

Angiomatoid fibrous histiocytoma (AFH) is a relatively rare soft tissue tumor of intermediate malignant potential, occurring most commonly in young adults, with a recognized propensity for local recurrence and occasional metastasis. A case of AFH occurring on the finger of a 60-year-old man is described in which the unusual location and age group for this entity raised the original wrong diagnosis of an aneurysmal and cellular fibrous histiocytoma. Further workup demonstrated an EWSR1-CREB1 translocation, confirming the correct diagnosis of AFH. Read More

Primary malignant fibrous histiocytoma, now classified as pleomorphic undifferentiated sarcoma, is the most common soft-tissue sarcoma in adult life. Primary splenic pleomorphic undifferentiated sarcoma is extremely rare and aggressive, and is associated with a poor prognosis; only 14 cases of splenic pleomorphic undifferentiated sarcoma have been documented in the English literature. We discuss a case of a 56-year-old woman with iron-deficiency anaemia, early satiety and left upper-quadrant pain, who was preoperatively diagnosed with a large splenic cyst following thorough investigation.

With a broad pattern of presentation, sometimes Nodular Fascitiis can have a rapid growth and appear highly cellular with local aggressiveness on biopsies, thus simulating a sarcoma. The aim of this paper is to present a case of troublesome diagnosis of nodular fascitiis mimicking a Malignant Fibrous Histiocytoma, with the purpose of alert clinicians and pathologists on the difficulties that can be met in the differential diagnosis between these 2 lesions.

Angiomatoid fibrous histiocytoma (AFH) can be diagnostically difficult because of its varied histologic appearance and potential to occur at unusual sites. The identification of recurrent rearrangements (EWSR1-CREB1, EWSR1-ATF1, and FUS-ATF1) is a helpful diagnostic tool. Additional immunohistochemical markers in AFH could aid in restricting the differential diagnosis and selecting appropriate cases for targeted molecular studies. Read More

Angiomatoid fibrous histiocytoma is a rarely metastasizing soft-tissue tumor of low-grade malignancy. Here we report a case of angiomatoid fibrous histiocytoma located in the leg of a 15-year-old female. This case is of particular interest due to its radiological features that led to raise two questions concerning the nature of the disease (is it reactive or tumoral?) and its site of origin (within soft tissues or the tibial periosteum?).

Undifferentiated pleomorphic sarcoma (UPS) is a high-grade pleomorphic neoplasm with no identifiable line(s) of differentiation using currently available diagnostic techniques. Therefore, it is essentially a diagnosis of exclusion, which requires generous tissue sampling, adequate contextually interpreted immunohistochemistry, and relevant molecular studies. UPS is a common soft tissue sarcoma (historically one of the entities referred to as malignant fibrous histiocytoma (MFH)), which can develop in various organs, but lung involvement is usually due to metastasis.

Melanoma-associated antigen 3 (MAGE-A3) expression is generally restricted to the placenta and germline cells of the testis, but it may also be expressed in sarcoma and other cancers and is associated with poor prognosis. Immunotherapy approaches targeting MAGE-A3 in other cancers have shown mixed results in the clinic, however, use of cancer testis antigens such as MAGE-A3 may have therapeutic value in the treatment of soft tissue sarcomas. Based on the recent success of anti-programmed death-1 (PD-1) therapy in undifferentiated pleomorphic sarcoma, we hypothesize that MAGE-A3-based immunotherapies may also provide benefits in this sarcoma type.
