Three hundred and two carcinomas of the female breast were studied histologically with special reference to the morphologic aspects of the tumor, its surrounding host tissue and the regional lymph nodes. The nuclear grade of the tumor was positively correlated with the five year survival rate of the patient. Tumor metastases in the regional lymph nodes were observed to be a sign of a poor prognosis. The stromal lymphocyte and mast cell reactions did not correlate with the frequency of nodal metastases or the five year survival rate. Sinus histiocytosis in the lymph nodes was a sign of favorable five year survival because of its presence in cancer-free nodes only. The paracortical activity of the lymph nodes was an important determinant of whether or not tumor metastases appear in the node.

One hundred and thirty eight gastric carcinomas were studied histologically with special reference to the morphology of the tumor, its surrounding tissues and the regional lymph nodes. A special search was focused on the morphologic manifestations of possible host factors in association with gastric carcinoma. The most prominent findings were as follows: 1. The nuclear grade of the tumor was positively correlated with the 5-year survival rate of the patients. 2. The content of tumor-derived mucus was not a prognostic determinant. 3. The intensity of the stromal lymphocyte and plasma cell reactions did not affect the prognosis but was inversely related to the frequency of nodal metastases. 4. Sinus histiocytosis and nodal mast cell reactions were an important determinant of whether nodal metastases appear or not. 5. An active paracortical area of the lymph node was almost incompatible with the appearance of nodal metastases.

Sinus histiocytosis with massive lymphadenopathy involving organs other than the lymph nodes is a rare event. A case of SIIML presenting with multiple skin and subcutaneous nodules and multiple osteolytic lesions is described. A search of the Indian literature revealed many cases of nodal SIIML, but none of the reported cases had prominent extranodal involvement.

Sinus histiocytosis with massive lymphadenopathy is a well recognised, but rare cause of lymphadenopathy in the first decade of life. Three cases presenting with nodal disease are described. The eyelids were involved in one case. The clinical, laboratory, and biopsy findings are discussed and compared with previously reported cases.

Sinus histiocytosis with massive lymphadenopathy (SHML) is a newly recognized disorder. The etiology of this disease is unknown. An exaggerated response to an offending agent such as the Epstein-Barr virus or Klebsiella bacteria has been postulated. Its course is usually benign. Cervical adenopathy is seen in 97% of the patients, while 30% of patients have nodal involvement in other sites, and 30% have extranodal involvement. There is a 7% mortality rate that occurs primarily in patients with immunologic defects. Corticosteroids ameliorate the constitutional symptoms, but cyclophosphamide appears to have the most beneficial effect. This article presents the case of a patient with SHML who demonstrated elevated Epstein-Barr virus titers.

Whereas Rosai-Dorfman disease (RDD) or sinus histiocytosis with massive lymphadenopathy is well described in lymph nodes and other organs, it is frequently not recognized in soft tissue. We studied the clinical and histologic features of 23 previously unreported soft tissue lesions from 17 patients (13 females, 4 males) who were 24 to 66 years of age (mean, 46 years). These lesions involved the extremities (12, 52%), trunk (6, 26%), head and neck (3, 13%), and the retroperitoneum (2, 9%). Associated lymph node involvement was present in four cases; most patients were asymptomatic. RDD of soft tissue had more subtle histologic features than its lymph node counterpart. Emperipolesis was less conspicuous and proliferating histiocytes were frequently spindled, associated with collagen deposition, and arranged in a vague storiform pattern with scattered lymphoplasmacytic aggregates. These features led to a variety of diagnoses, including benign inflammatory and fibrohistiocytic lesions (13 cases) as well as lymphoma and malignant fibrous histiocytoma (three cases). RDD was correctly diagnosed in only one case. Diagnosis was confirmed in 16 of 18 lesions by detection of S-100 protein and histiocytic markers KP1 (12 of 13) and lysozyme (eight of 11) in the characteristic histiocytes. Recognition that RDD of soft tissue occurs in an older patient population than does nodal RDD and that it mimics fibrous and inflammatory lesions of soft tissue is important.

Sinus histiocytosis with massive lymphadenopathy (SHML), introduced in 1969 by Rosai and Dorfman, is a benign and self-limited (albeit often relapsing) pseudolymphomatous entity with characteristic histopathologic features. Although the presence of massive cervical lymphadenopathy often aids in the diagnosis of SHML, the disease may present in the absence of detectable nodal involvement (Rosai-Dorfman disease). Therefore, the physician must be aware of such extranodal presentations. A recent review of the 365 cases in the SHML registry has revealed a preponderance of eyelid and/or orbital involvement; only 26 cases were found with subcutaneous or soft tissue involvement in areas other than the eyelid and/or orbit. This is a case report of one such atypical presentation of SHML without clinically apparent lymphadenopathy or eyelid or orbital involvement.

Sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease) is a unique disease of unknown etiology with a childhood predilection. Reports have established the worldwide distribution of the disorder. Although peripheral lymphadenopathy is the most common mode of presentation, numerous studies and individual case reports have established the fact that 30-40% of affected individuals have extranodal manifestations particularly in the head and neck region where the adenopathy tends to be concentrated. As yet, the pathogenesis of SHML has not been established but speculation relates the disorder to an aberrant response to an unspecified antigen, possibly an infectious organism. Because of the clinical manifestations, the radiographic features of SHML are not pathognomonic but rather engender a differential diagnosis which includes lymphomatous, pseudolymphomatous and infectious conditions. Appropriate imaging of patients with SHML depends upon presenting symptoms and signs. Radionuclide bone scanning may be helpful in the evaluation of suspected skeletal lesions or joint symptoms. Gallium scanning is often positive in nodal disease and CT, MRI and sonography are helpful in the evaluation of extranodal sites of involvement such as the orbit, eyelid, upper aero-digestive tract and retroperitoneum.

We report the histological findings seen in the lymph nodes draining the sites of large joint prostheses. Two patients underwent multiple prosthetic joint replacements. In one patient, the regional lymph nodes were enlarged during the revision of a total hip prosthesis, and a representative lymph node was resected. The other patient had undergone a pelvic lymph node dissection as part of a staging procedure for prostatic carcinoma. By light microscopy, the lymph nodes from both patients showed markedly dilated nodal sinuses filled with macrophages containing abundant eosinophilic, PAS-positive, granular material. Polarization microscopy revealed needle-like particles within the cytoplasm of the macrophages. We believe that the histological appearance of the lymph nodes represents a florid foreign body reaction to fragments of polyester or polyethylene derived from the articulating surfaces of the joint prostheses and transported to the regional lymph nodes via the lymphatic circulation. Sinus histiocytosis seen in the lymph nodes draining the sites of joint prostheses may resemble, and must be distinguished from, other conditions invoking a sinus pattern of lymphadenopathy, as well from benign and malignant diseases that involve the lymph nodes in a pattern mimicking sinus histiocytosis.

A single osteolytic bone tumour with a cellular composition similar to that of the extra-nodal localization of Sinus Histiocytosis with Massive Lymphadenopathy although with greater cellular atypicality is described. This histological similarity suggests the possible occurrence of isolated bone involvement of Rosai-Dorfman disease, with atypical cytology but benign evolution, which has not been reported in the literature.
