Primary Sclerosing Epithelioid Fibrosarcoma of the Lung in a Patient with Lynch Syndrome


Leisibach, Priska; Weder, Walter; Soltermann, Alex; Jungraithmayr, Wolfgang (2012). Primary Sclerosing Epithelioid Fibrosarcoma of the Lung in a Patient with Lynch Syndrome. Lung, 190(6):691-695.

Abstract

Sclerosing epithelioid fibrosarcoma (SEF) is a rare neoplasm arising mostly in limbs and limb girdles, with a high rate of recurrence and a strong tendency to metastasize. This case study is of a 54-year-old woman with an asymptomatic mass in the upper lobe of the left lung detected by PET-CT when staging for Lynch syndrome-associated colon carcinoma. Histology of the resected tumor showed epithelioid cells arranged in nests, partly restiform within a zone of sclerosing fibrosis. Immunohistochemistry was positive for vimentin, epithelial membrane antigen, and S100-protein. Eight months after lung resection, the patient was diagnosed for basal cell carcinoma on her back. At the end of a two year follow-up period, she developed metastases to the mediastinum, vertebrae, ribs, femurs, pelvic bones, kidneys, and one lung, histologically all related to SEF. Here we report the first case of a SEF primarily arising from the lung and discuss it in the context of the current literature.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
