“…Within this group of xanthomatous lesions, the rare condition usually known as generalised reticulohistiocytosis is to be distinguished from giant-cell tumour of soft tissues by the presence of multiple lesions, as well as by differences of histological structure. It is a systemic condition that may involve joints, lymphnodes, larynx, endocardium, bone marrow and muscles in addition to skin and subcutaneous tissue (Montgomery and O'Leary, 1934;Weber and Freudenthal, 1937;Weber, 1943;Warin et al, 1957;Lye11 and Carr, 1959).…”
