Postmastectomy lymphangiosarcoma: a reappraisal of the concept—a critical review and report of an illustrative case

Abstract

The syndrome of postmastectomy lymphangiosarcoma (LAS) has been universally accepted since it was first outlined by Stewart & Treves (1948), except for a small number of authors who concluded that the neoplasms arising in the chronic lymphoedematous arms were in fact due to retrograde spread from the original breast carcinoma (Laffargue, Pinet & le Go 1960, Giannardi, Pelù & Zampi 1960, Giannardi & Pelù 1961, Delarue 1962, Salm 1963, Laugier, Olmos, Hunziker & Orusco 1973), but their views have been largely ignored. A case is reported in whom neoplastic arm lesions appeared 27 years after mastectomy and were due, in our opinion, to recent metastases from a new primary Carcinoma of the lung. The validity of the entire concept of LAS is re-examined.
