Intracranial Myxoid Mesenchymal Tumor/Myxoid Subtype Angiomatous Fibrous Histiocytoma: Diagnostic and Prognostic Challenges.

Neurosurgery 2020 12;88(1):E114-E122

Department of Neurologic Surgery, Mayo Clinic, Jacksonville, Florida.

Background And Importance: In the setting of intracranial neoplasms, EWSR1-cAMP Response Element-Binding Protein (CREB) transcription factor family fusions have been described in myxoid mesenchymal tumors, extremely rare entities with a close histopathologic and immunologic resemblance to myxoid subtype angiomatoid fibrous histiocytomas (AFH). Controversy exists on whether these central nervous system lesions are a subtype of myxoid AFH or a completely separate entity, which entitles a distinct clinical behavior and, consequently, a different approach to management. Upon review of the literature, only 14 cases of intracranial tumors harboring an EWSR1-CREB family fusion were identified, with only 3 cases presenting in middle-aged adults, none of which reported an EWSR1-CREM fusion mutation.

Broadening the spectrum of NTRK rearranged mesenchymal tumors and usefulness of pan-TRK immunohistochemistry for identification of NTRK fusions.

Mod Pathol 2021 02 28;34(2):396-407. Epub 2020 Aug 28.

Diagnostic and Research Institute of Pathology, Comprehensive Cancer Centre Graz, Medical University of Graz, Graz, Austria.

Fusions involving NTRK1, NTRK2, and NTRK3 are oncogenic drivers occurring in a spectrum of mesenchymal neoplasms ranging from benign to highly malignant tumors. To gain further insights into the staining profile with the pan-TRK assay, we analyzed a large number of soft tissue sarcomas and correlated our findings with molecular testing. Additionally, we expand the spectrum of NTRK-fusion tumors by reporting a mesenchymal lesion in the lung as well as a mesenchymal skin lesion in the spectrum of benign fibrous histiocytoma with NTRK-fusion.

Primary Pulmonary Myxoid Sarcoma and Myxoid Angiomatoid Fibrous Histiocytoma: A Unifying Continuum With Shared and Distinct Features.

Am J Surg Pathol 2020 11;44(11):1535-1540

Department of Pathology and Laboratory Medicine, Hospital of the University of Pennsylvania.

Primary pulmonary myxoid sarcoma (PPMS) is a recently reported, exceedingly rare low-grade lung neoplasm characterized by reticular/lace-like growth of spindle to epithelioid cells embedded in an abundant myxoid matrix. Morphologically, it overlaps with a myxoid variant of angiomatoid fibrous histiocytoma (AFH) of the soft tissue. Genetically, they were both reported to harbor EWSR1-CREB1 fusion, while EWSR1-ATF1 has only been reported in AFH thus far. Read More

EWSR1/FUS-CREB fusions define a distinctive malignant epithelioid neoplasm with predilection for mesothelial-lined cavities.

Mod Pathol 2020 11 7;33(11):2233-2243. Epub 2020 Aug 7.

Department of Pathology, Memorial Sloan Kettering Cancer Center, New York, NY, USA.

Gene fusions constitute pivotal driver mutations often encoding aberrant chimeric transcription factors. However, an increasing number of gene fusion events have been shown not to be histotype specific and shared among different tumor types, otherwise completely unrelated clinically or phenotypically. One such remarkable example of chromosomal translocation promiscuity is represented by fusions between EWSR1 or FUS with genes encoding for CREB-transcription factors family (ATF1, CREB1, and CREM), driving the pathogenesis of various tumor types spanning mesenchymal, neuroectodermal, and epithelial lineages.

Cutaneous undifferentiated pleomorphic sarcoma is a pleomorphic dermal sarcoma.

Philip R Cohen

Dermatol Online J 2020 May 15;26(5). Epub 2020 May 15.

San Diego Family Dermatology, National City, CA Touro University California College of Osteopathic Medicine, Vallejo, CA Scripps Family Medicine Residency, Scripps Mercy Hospital Chula Vista, Chula Vista, CA Family Medicine Residency, Family Health Centers of San Diego, San Diego, CA.

Pleomorphic dermal sarcoma is a cutaneous soft tissue sarcoma that presents as a rapidly enlarging tumor, typically on a sun-exposed location of elderly individuals. The neoplasm shares many similar features - clinical, pathologic, immunohistochemical and genomic - with atypical fibroxanthoma. However, adverse histologic characteristics (deep subcutaneous invasion, tumor necrosis, lymphovascular invasion, and/or perineural invasion) differentiate pleomorphic dermal sarcoma from atypical fibroxanthoma and may account for the more aggressive biologic behavior of pleomorphic dermal sarcoma: local recurrence and metastases.

Clinical relevance and functional significance of cell-free microRNA-1260b expression profiles in infiltrative myxofibrosarcoma.

Sci Rep 2020 06 10;10(1):9414. Epub 2020 Jun 10.

Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama, Japan.

Infiltrative tumor growth into adjacent soft tissues is a major cause of the frequent recurrence and tumor-related death of myxofibrosarcoma (MFS), but no useful biomarkers reflecting tumor burden and infiltrative growth are available. While emerging evidence suggests a diagnostic and functional role of extracellular/circulating microRNA (miRNA) in various malignant diseases, their significance in MFS patients remains unknown. Global miRNA profiling identified four upregulated miRNAs in MFS patient sera and culture media of MFS cells. Read More

Angiomatoid Fibrous Histiocytoma With ALK Expression in an Unusual Location and Age Group.

Am J Dermatopathol 2020 Sep;42(9):689-693

Cellular Pathology, St George's University Hospital, London, United Kingdom.

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
