General
=========================================================================

● Histiocytic proliferation with emperipolesis in background of plasma cells and lymphocytes
● First described by Destombes (1965), Rosai and Dorfman (Arch Pathol 1969;87:63)
● Also called sinus histiocytosis with massive lymphadenopathy
● Unknown origin, but associated with immunologic abnormalities

Clinical features
=========================================================================

● Rarely presents as salivary gland involvement without significant lymphadenopathy
● Usually long clinical course with exacerbations and remissions and eventual complete remission
● Primarily submandibular and parotid glands

Case reports
=========================================================================

● 9 and 10 year old brothers (Dentomaxillofac Radiol 2007;36:428)
● 44 year old man with involvement of salivary glands, cervical lymph nodes, nasal and maxillary sinus mucosa (J Cytol 2009;26:111)
● 45 yr old woman with enlarged submandibular gland (Diagn Cytopathol 2005;33:187)
● 48 year old with systemic lupus erythematosus and parotid gland involvement (Arch Pathol Lab Med 2001;125:1348)
● 71 year old man with parotid mass (J Laryngol Otol 1997;111:1091)
