The head and neck region is - among the body regions - one of the most frequently affected one by malignant primaries in childhood and adolescence. The diagnosis of malignant lymphomas (Hodgkin's and non-Hodgkin's type) predominanted (55 cases) in the own case material of 94 patients. Besides, there were 21 tumors of mesenchymal origin, 11 neuroepithelial tumors and 5 cases of histiocytosis X. The first symptoms are often discret (painless swelling) and they represent one of the major problems in handling childhood tumors. An optimal therapy, which resulted in longterm cures in the majority of the own patients, is based on an intensive team-work of pediatricians and ENT-doctors. One of the important points for successful treatment is individualizing the intensity of each of the effectful modern therapeutic modalities.

In a retrospective review of sequential biopsies in 8 cases of histiocytosis X, 2 developed xanthomatous or fibrous lesions, 3 remained unchanged, whereas 3 developed malignant disease, one Hodgkin's disease and 2 malignant histiocytosis. A possible progression from benign, well differentiated to malignant histiocytic lesion is discussed, and the importance of achieving a microscopic diagnosis is emphasized.

When ficoll purified peripheral blood lymphocytes were treated with fluorescein conjugated lectins from lentils (LCH), castor beans (RCA) and phaseolus coccineus beans (L-and E-PHA) for 15 min and the percentages of the cap forming cells were examined, the values of leukemic lymphocytes were reduced compared to the values obtained with normal lymphocytes. The reduction was more than half in patients with acute and chronic myelogenous leukemia and immunoblastoma, it was only one quarter in patients with chronic lymphocytic leukemia, Hodgkin's disease and lymphosarcoma. The lowest number of cap forming cells was found in lymphoblasts of established lymphoblastoid cell lines. The four different lectins showed nearly the same capacity in the induction of caps. After successive binding, the different lectins showed cocapping on the lymphocyte surface.

Characteristic mononuclear cells with distorted nuclei and abundant pale-staining cytoplasms together with osteoclast-like giant cells are the cytologic hallmarks of histiocytosis X. The demonstration of acid phosphatase within giant cells in paraffin-embedded sections is a valuable aid to diagnosis. The histologic differential diagnosis of histiocytosis X includes some allergic granulomas, Hodgkin's disease, myelomonocytic leukemia, mastocytosis, and malignant histiocytosis. Some technical prerequisites for accurate diagnosis of histiocytosis X are considered briefly.

The overall 38% response rate in histiocytosis X for cyclophosphamide, vincristine (Oncovin), prednisone, and procarbazine was not superior to responses that can be achieved with the component single agents. This is in contrast to the higher response rates that can be achieved by the combination of these agents in Hodgkin's disease. This is the second study of combination chemotherapy with individually effective agents that has failed to improve the response rates in histiocytosis patients with poor prognostic indicators.

Closed trephine needle biopsy of the bone marrow has become an established procedure in the evaluation of many malignant and benign diseases in adults; however, its role in pediatric pathology has not yet been defined. In the period from February 1974 to April 1978 we have performed 164 such biopsies in 111 children under 15 years of age. A representative specimen has been obtained in over 80% of cases. This series included, in order of frequency, non-Hodgkin lymphomas, Hodgkin lymphomas, aplastic anemias, rhabdomyosarcomas, neuroblastomas, miscellaneous solid tumors, and single cases of histiocytosis X, malignant histiocytosis, sarcoidosis, malignant histiocytoma, and Castleman lymphoma of the hyaline-vascular type. Histology has been found superior to cytology in the detection of neuroblastoma invasion; the evaluation of the true cellularity in aplastic anemia, and the detection of granulomatous tissue in the only case of sarcoidosis. In other diseases histology and cytology gave similar information, except for the few cases of acute leukemia in partial relapse, which has been better defined in the aspirate smears than in the core specimen. Further evaluation of this technique in other patient series appears advisable.

Using a monoclonal antibody specific to the Lewis X antigen (anti-Lex), the authors studied 103 cases of Hodgkin's disease (HD) in comparison with 57 cases of non-Hodgkin's lymphoma (NHL); three cases of granulocytic sarcoma (GS); two cases of malignant histiocytosis (MH); one case of monoblastic leukemia (ML); one case of interdigitating reticulum cell sarcoma (IRCS); six cases of histiocytosis X (HX); one case of reticulohistiocytoma (RH); 44 various reactive conditions of the lymph node (LN). Reed-Sternberg and related (R-S) cells stained selectively in 80 of 92 cases of HD (87.0%), excluding 11 cases of lymphocyte predominance type. The stain was better in B-5-fixed specimens than in formalin-fixed specimens, showing a dense deposit of reaction products at a paranuclear site and on the cell surface. The staining results were compared with those of Leu-M1 and found to be superior both qualitatively and quantitatively (detection rate of R-S cells: 87.0% versus 68.5% of Leu-M1). Granulocytes, rare epithelioid histiocytes, and some endothelial and/or erythrocytes also stained with anti-Lex. The stain had positive results in three cases of GS showing a diffuse cytoplasmic staining pattern. Of NHL, two of 29 peripheral T-cell lymphomas stained to show rare paranuclear deposits without cell surface staining. The stain had negative results in MH, ML, IRCS, HX, and RH. Of 45 reactive LN, minute subcapsular collections of Lewis X+, altered-appearing Langerhans'-like cells, were observed in all ten LN from human immunodeficiency virus (HIV)-associated persistent generalized lymphadenopathy (PGL). The stain had negative results in all other various reactive conditions of LN. In conclusion, Lewis X staining is useful as a marker for R-S cells in paraffin sections with staining results superior to those of Leu-M1. Lewis X staining also detects subcapsular clustering of altered-appearing Langerhans'-like cells in PGL, which has not been described previously and warrants additional study.

This report describes the antigenic profile of the proliferating cells of pulmonary histiocytosis X (HX) in a patient treated with chemotherapy for Hodgkin's lymphoma; the association of pulmonary HX and Hodgkin's disease has rarely been described in the literature. The histopathological diagnosis of HX was confirmed with the aid of monoclonal antibodies (mAbs) to CD4, CD1a, and polyclonal serum anti S-100 protein. The phenotype of HX cells has been analysed using a panel of mAbs against HLA class I A, B, C monomorphic determinants, locus A and B, beta 2-microglobulin, HLA class II distinct monomorphic determinants, DP, DQ, DR, intercellular adhesion molecule-1 (ICAM-1) and vitronectin receptors. Our results indicate that HX cells express HLA class I and II, including locus A, locus B and DP, DQ, DR, like their normal counterpart (represented by Langerhans cells) and detectable levels of ICAM-1 but not vitronectin receptors. We would like to stress the possibility of the association of HX and Hodgkin's lymphoma extending the immunophenotypic profile of HX cells.

Since multiple primary malignant tumors are rare in children, their presence can be a diagnostic and therapeutic problem. In this report, we present a six-year-old boy with Langerhans cell histiocytosis and Hodgkin's disease. On admission, the patient had lytic lesions and a periosteal reaction on the left trochanter major from which an open bone marrow biopsy was performed. The biopsy revealed Langerhans cell histiocytosis. Eight months later, the child presented with enlarged left cervical lymph nodes and the biopsy demonstrated Hodgkin's disease. Although there was an eight-month interval between the two histopathological diagnoses, the diffuse pulmonary parenchymal infiltration observed on the first admission, was later confirmed by an open-lung biopsy as Hodgkin's disease. The patient was said to have two concurrent lymphoreticular malignancies. To our knowledge, this is the youngest case reported with this association in the English language literature.

Lymphoproliferative disorders are the frequent cause of indeterminate processes in the head and neck region for which otolaryngologists are often consulted by colleagues seeking a diagnosis. Because a wide spectrum of diseases may be represented, tissue diagnosis is often required. Recent advances in tissue immunotyping and DNA probes permit more precise identification and classification of these disorders. Lymphoproliferative disorders may be subdivided into five categories: Hodgkin's disease, non-Hodgkin's lymphoma, histiocytosis X, benign reactive lymphoproliferative disorders, and plasma cell neoplasms. Representative cases are presented, along with a brief discussion of each category.
