Abstract

To date, the morphological aspects of sinus histiocytosis with massive lymphadenopathy (SHML) have been fully described. The disease is characterized by an enlargement of lymph nodes in which the sinuses are dilated and infiltrated by histiocytes, often phagocytosing lymphocytes. Even if the prognosis is usually benign and not requiring therapy, several fatal cases have been reported. The etiology is still obscure and the biology is not yet completely clear. Recent immunophenotypical studies suggest that histiocytes may belong to the T-zone associated histiocyte lineage. They may be cytologically homogeneous, but can express different antigenic patterns according to their stage of differentiation. Cytogenetic and molecular aspects of the disease have only been sporadically investigated. In order to better understand the pathogenesis of SHML, which seems to be a disorder lying in between the fields of infections, immunological disease and neoplasia, it is considered very useful to systematically employ a variety of immunophenotypical, cytogenetic and molecular techniques to study the disease, particularly in cases which are clinically atypical or with a more aggressive evolution.
