Sinus histiocytosis with massive lymphadenopathy may involve extra-nodal tissue sites. Skeletal involvement is uncommon and has always been associated with disease in other nonosseous locations. The present case is the first to document sinus histiocytosis with massive lymphadenopathy arising primarily within bone and unaccompanied by disease elsewhere.

Sinus histiocytosis in the regional lymph nodes of 45 patients with breast cancer who had undergone extended radical mastectomy was studied by histological examination of 2,294 resected lymph nodes. Sinus histiocytosis was divided into three grades, marked, moderate, and mild to negative, by Ohmori's classification. The results indicated that: 1) sinus histiocytosis correlates fairly well with clinical stage, especially with the n-factor, and 2) the degree of sinus histiocytosis shows little difference between three groups of regional lymph nodes. The authors concluded that sinus histiocytosis dominates the prognosis and represents some aspect of a reticuloendothelial response of the whole body to carcinoma.

The association of adenopathies, having sometimes a tumoral aspect, and a polyclonal hypergammaglobulinemia in the blood can be observed in various illnesses. In all these diseases the increase in the volume of the lymph nodes is partly due to the hyperplasia of the lymphoid B regions. Lymph node biopsy allows a precise diagnosis to be made, providing a thorough analytical study of the histopathological lesions is performed. In this first part, the histopathological lesions of benign lymphadenitis, having a pseudo-tumoral aspect from a clinical view, are described. The following are thus successively studied: sarcoidosis; acquired toxoplasmosis; the various aspects which can be attributed to infectious mononucleosis; vaccinal reactions; the Destombes-Rosai-Dorfman syndrome or massive lymphadenopathy by sinusal histiocytosis with hemophagocytosis; angiofollicular lymphoid hyperplasia or pseudo-tumour of Castleman; angio-follicular and plasmocytic polyadenopathy; the adenopathies of collagenosis and those due to protein deposits. For each disease, the morphological data are discussed and compared to clinical state and biological modifications.

Sinus histiocytosis with massive lymphadenopathy (SHML) is generally regarded as a benign disorder in spite of its propensity to form large masses and to disseminate to both nodal and extranodal sites. Although in most patients the extent of SHML does not appear to determine disease outcome, recent reports have documented that infiltrates of SHML can cause death. To gain perspective on the role of SHML in patient deaths in this population, the authors analyzed the 14 known fatalities in an SHML registry comprising 215 patients. The average age at death was 33 years. Autopsy was performed on eight patients. SHML infiltrates were clearly the cause of death in only two patients (previously reported). In another four cases persistent SHML was prominent at death. The other deaths were the result of complications of defined immunologic abnormalities (five), or of unusual infections (three). The authors have not seen an example of cytologic malignant transformation of SHML.

Sinus histiocytosis with massive lymphadenopathy (SHML) is generally regarded as a benign, self-limited, pseudolymphomatous process requiring little or no therapy. We studied a 13-year-old black boy with a ten-year clinical course of SHML that had varying, intermittent sites of extranodal involvement, including bone, submandibular gland, trachea, eye, and spinal cord. At the time of death, which was attributed to SHML, additional extranodal sites of involvement included thymus, kidney, heart, liver, and base of brain. Microscopic examination of the SHML lesions at the time of autopsy revealed varying stages of development, from proliferation to involution. This case illustrates that SHML may involve multiple organ systems, can kill, and that histologic evaluation of disease activity at one site cannot be used as an indicator of activity at another.

Histological, histomorphometrical and histochemical data on the response of regional lymph nodes to tumor development, as recorded in experimental and clinical studies, were coordinated and supplemented by recent findings in experimentally induced autochthonous carcinomas in the rat gastrointestinal tract. The attempted correlation led to the definition of several prognostic parameters: 1) The development of germinal centers and the plasmocytic reaction in tumor draining nodes are morphological expressions of active humoral immune responses that may be specifically directed against the tumor. These reactions attain their maximum usually during late stages of tumor development. Their incidence and prognostic significance may vary depending upon the stage and the type of tumor. 2) Sinus histiocytosis is an immunologically nonspecific lymph node response with debatable prognostic significance. 3) Granulomatous sarcoid-like lesions may be understood as signs of an immunologically mediated antitumor response of macrophages activated by T lymphocytes. They are indicative of a favorable prognosis. 4) Paracortical hyperplasia, characterized by an increased population of lymphocytes and eventually immunoblasts, is an expression of an active T-cell reaction. This reaction occurs typically during early stages of experimental tumors. Correspondingly, it is of favorable prognostic significance in human tumors. 5) Lymphocytic depletion and nodular alteration of T-cell areas, with increased histiocytic infiltration, are reactions most often seen in the draining nodes of an advanced tumor. Both seem to coincide with depression of the cell-mediated immune reactivity. The present assessment of the reactive behavior of diverse lymph node compartments may serve as a first pointer to the proposed histologic immunostaging of malignant tumors.

The sinuses of the axillary nodes were studied in 59 breast cancer patients. Three types of reaction were defined in them; sinus histiocytosis, a mixed sinus reaction, and sinus catarrh. Sinus histiocytosis, as defined here, was virtually confined to the mode-negative cases; sinus catarrh, common to both node-negative and positive, but increasing with tumour size in the former. It is suggested that transition may occur from sinus histiocytosis, via the mixed reaction, to sinus catarrh, and that the establishment of the latter may facilitate tumour spread.

Sinus histiocytosis with massive lymphadenopathy is a benign pseudolymphomatous disease with distinctive microscopic features. Painless cervical adenopathy is the most characteristic clinical finding, although other node groups and extranodal sites may be involved. Of 200 patients in a case registry, 8 had neurologic symptoms. The lesions included vertebral canal and intracranial infiltrates and a destructive vertebral body lesion. Two patients had both cord compression and intracranial disease; one of them died after 10 years of disease. Seven patients were alive 1 to 15 years after disease onset.

Investigated were lymph nodes in a group of patients with spinocellular carcinoma of the oral cavity. As regards patient survival, lymphocyte predominance and sinus histiocytosis manifest prognostically the most favorable changes. A predominance of germinal follicle centers in our group of patients cannot be interpreted as indicator of an improved prognosis. Sinus histiocytosis has never been found in nodes with metastases.

A fatal case of sinus histiocytosis with massive lymphadenopathy (SHML) is described in a male patient who presented at 11 years-of-age with swelling of the malar region and nasal obstruction due to the disease and who died aged 28 in uraemic coma following renal involvement. At autopsy SHML tissue extended into the hilum of both lungs and from the retroperitoneal tissue into the pancreas and kidneys. The appearances suggest that the extension of the disease into these organs may have been due to retrograde lymphatic spread from involved lymph nodes. Replacement of the atypical sinus histiocyte by fibrous tissue was seen in the cervical lymph nodes and this may be the usual mode of resolution of the lesion. The nature of SHML is discussed in relation to a possible infectious aetiology and defects in the host immune system. Finally, it is noted that the term 'massive lymphadenopathy' is not applicable to all cases and that sinus histiocytosis in not appropriate for the now frequently recognized extranodal manifestations of the disease. It is proposed that the term 'lymphophagocytic histiocytosis syndrome' should be adopted or that the eponymous title 'Rosai-Dorfman disease' should be used.
