Fifty nodes of
Hodgkin's disease
, 50 of non-Hodgkin's lymphoma and 20 of reactive hyperplasia revealed varying degree of
mast cell
reactivity. It was maximum in reactive lymph nodes, sinuses and interfollicular areas being infiltrated more than zones. The number of mast cells was more in nodular sclerosis variety of
Hodgkin's disease
than other Rye-subtypes, and more in
Hodgkin
's group than non-
Hodgkin
's, out of the latter, the diffuse histiocytic lymphoma revealed higher number. Analysis of a larger series and follow-up of these patients are indicated to establish the possible reactionary nature of
mast cell
reactivity in lymphomas, and the prognostic bearing, if any.

The bone marrow examination is useful in the diagnosis and management of patients with malignant lymphoma. Demonstration of marrow lymphoma is dependent on obtaining adequate and properly prepared tissue for examination. The incidence and pattern of marrow disease differ for the various Working Formulation classes of non-Hodgkin's lymphoma (NHL); low grade and high-grade NHL have the highest incidence of marrow involvement at diagnosis.
Hodgkin's disease
involves the marrow less commonly than NHL and is found in a histologic environment similar to that in lymph node biopsies. Several benign lesions, including reactive lymphoid aggregates, granulomas, immunoblastic lymphadenopathy, and
mast cell
disease, must be distinguished from NHL or
Hodgkin's disease
in some instances.

We present a case of systemic
mast cell
disease because of its unusual lack of significant manifestations in skin or bone. Clinicians and pathologists alike must be aware of this entity and consider it when atypical round cell infiltrates are present in visceral organs. It should be included in a differential diagnosis with
Hodgkin
's and non-
Hodgkin
's lymphomas, leukemias, myeloproliferative disorders, and a variety of nonneoplastic diseases. Cytochemical stains and electron microscopy may be diagnostic.

Interleukin-9 (IL-9) is a multifunctional cytokine produced by activated TH2 clones in vitro and during TH2-like T cell responses in vivo. The IL-9 receptor is a member of the hemopoietin receptor superfamily and interacts with the gamma chain of the IL-2 receptor for signal transduction. Various observations indicate that IL-9 is actively involved in
mast cell
responses by inducing the proliferation and differentiation of these cells. The role of IL-9 in T cell responses is less clear. Although freshly isolated normal T cells do not respond to IL-9, this cytokine induces the proliferation of murine T cell lymphomas in vitro and in vivo overexpression of IL-9 results in the development of thymic lymphomas. In the human, the existence of an IL-9-mediated autocrine loop has been suggested for some malignancies such as
Hodgkin's disease
. Other potential biological targets for IL-9 include B lymphocytes, hematopoietic progenitors, and immature neuronal cell lines.

Lymphoreticular neoplasms of the larynx are rare and comprise a heterogeneous group of tumors. A systematic survey of the literature and autoptic evaluation of the larynx in a relatively small number of patients with systemic lymphoreticular malignancies yielded the following findings: Primary tumors of the larynx must be clearly distinguished from laryngeal involvement by systemic or leukemic infiltrations. By far the most common primary hemopoietic tumors of the larynx are extramedullary plasmacytoma (about 90 cases published) and non-Hodgkin's lymphoma (NHL; about 65 cases published). Primary
Hodgkin's disease
, granulocytic sarcoma and
mast cell
sarcoma are extremely rare at this site. Plasmacytoma and NHL both preferentially involve the supraglottis. The subglottis is infrequently affected. Laryngeal plasmacytoma and NHL usually present clinically as localized stage IE and IIE tumors that exhibit no significant tendency to recur or generalize. The therapy of choice is local irradiation while chemotherapy should be reserved for recurrent or progressive disease. Prognosis is favourable in most cases of primary laryngeal plasmacytoma and NHL. Secondary involvement of the larynx by systemic lesions or leukemic infiltrations is usually associated with a very poor prognosis. The prognosis of patients with laryngeal involvement in acute or chronic myeloid leukemia is always poor. Although the histopathological diagnoses given in many case reports are often difficult to compare because of differences in terminology, there seems to be a marked preponderance of B-cell tumors of high-grade malignancy (centroblastic or immunoblastic lymphoma in the Kiel classification of NHL) that probably represents lymphomas originating from mucosa-associated lymphoid tissue (MALT).(ABSTRACT TRUNCATED AT 250 WORDS)

Systemic mast cell disease is characterized by an abnormal infiltration of mast cells involving several parenchymal organs and the bone marrow. Its spectrum of clinical and histologic presentation is highly variable and is not necessarily correlated with prognosis. Mast cell disorders presenting as atypical infiltrates in the bone marrow may simulate or be associated with other hematolymphoid malignancies, from which they must be distinguished. The paucity of reliable histochemical and immunohistochemical markers for the detection of mast cells in paraffin sections further confounds this diagnosis. The authors have employed immunohistochemistry for the C-KIT encoded tyrosine kinase receptor protein, CD117, for detection of mast cells on paraffin sections of 89 bone marrow specimens including systemic
mast cell
disease and other disorders. CD117 staining was found in all cases of
mast cell
disorders (seven of seven), and in one case of chronic myelogenous leukemia in blast crisis. None of the other myeloid disorders tested (0 of 16), or any of the cases of
Hodgkin's disease
(0 of 12), B-cell lymphomas (0 of 32), T-cell lymphomas (0 of 3), or histiocytic proliferations (0 of 3) showed staining for CD117. CD117 expression is effective in the separation of
mast cell
disease from disorders that may simulate it histologically.

This randomized, controlled study compared the ability to mobilize and collect an optimal target yield of 5 x 10(6) CD34+ cells/kg using stem cell factor (SCF; 20 microg/kg/day) plus filgrastim (G-CSF; 10 microg/kg/day) vs filgrastim alone (10 microg/kg/day) in 102 patients diagnosed with non-Hodgkin's lymphoma (NHL) or
Hodgkin's disease
(HD), who were prospectively defined as being heavily pretreated. Leukapheresis began on day 5 of cytokine administration and continued daily until the target yield was reached, or until a maximum of five leukaphereses had been performed. Compared with the filgrastim-alone group (n = 54), the SCF plus filgrastim group (n = 48) showed an increase in the proportion of patients reaching the target yield within five leukaphereses (44% vs 17%, P = 0.002); reduction in the number of leukaphereses required to reach the target yield (P = 0.003); reduction in the proportion of patients failing to reach a minimum yield of 1 x 10(6) CD34+ cells/kg to proceed to transplant (16% vs 26%, P = NS); increase in the median yield of CD34+ cells per leukapheresis (0.73 x 10(6)/kg vs 0.48 x 10(6)/kg, P = 0.04); and an increase in the median total CD34+ cells collected within five leukaphereses (3.6 x 10(6)/kg vs 2.4 x 10(6)/kg, P = 0.05). All patients receiving SCF were premedicated (antihistamines and albuterol), and treatment was generally well tolerated. Five patients experienced severe
mast cell
-mediated reactions, none of which were life-threatening. In this study of heavily pretreated lymphoma patients, SCF plus filgrastim was more effective than filgrastim alone for mobilizing PBPC for harvesting and transplantation after high-dose chemotherapy.

Hodgkin's disease
(HD) tumours are characterized by the presence of few tumour cells, the
Hodgkin
and Reed-Sternberg (HRS) cells, surrounded by a large amount of non-neoplastic cells. The role of this cell infiltrate for the development of HD is not known. CD30, belonging to the tumour necrosis factor receptor superfamily, is highly expressed on HRS cells and believed to be involved in tumourigenesis and tumour progression. Tumour samples from 42 patients were immunohistochemically double-stained for tryptase, a
mast cell
-specific proteinase and CD30 ligand (CD30L). Tryptase-positive mast cells were present in all tumours. Of these cells, 50% expressed CD30L and 66% of the CD30L-positive cells were mast cells. CD30L mRNA in in vitro developed normal mast cells and malignant human and murine
mast cell
lines was detected using reverse transcription polymerase chain reaction. CD30L protein expressed on human mast cells was detected using flow cytometry. In a co-culture assay, the human
mast cell
line HMC-1 stimulated thymidine uptake in HRS cell lines, and the stimulation could be blocked using CD30L-specific monoclonal antibodies. In conclusion, mast cells are present in HD tumours and are the predominant CD30L-expressing cells. CD30L-CD30 interaction is a pathway by which mast cells may stimulate DNA synthesis in HRS cells.

The REAL Classification of lymphomas, proposed in 1994, represents a new paradigm in lymphoma classification, consisting of a list of biologic entities defined by clinicopathologic and immunogenetic features. The non-
Hodgkin
's lymphomas comprise precursor lymphoblastic and mature cell neoplasms of B, T or putative natural killer cell lineage. An individual entity can exhibit a range of morphologic appearances and a range of clinical behavior. The categories in
Hodgkin
's lymphomas are identical to the widely used Rye classification except for the additional of a new category termed 'lymphocyte-rich classical
Hodgkin's lymphoma
'. The REAL classification has been validated by a major multi-institutional study involving 1378 cases (The Non-Hodgkin's Lymphoma Classification Project), showing that it is both reproducible and clinically relevant. The new World Health Organization classification of hematopoietic and lymphoid tumors, to be published in 2001, is a joint project of the Society for Hematopathology and European Association of Hematopathologists, under the auspices of the World Health Organization. This classification includes not only lymphoid neoplasms, but also myeloid, histiocytic and
mast cell
neoplasms. The lymphoma component of the classification is merely an update of the REAL classification, with minor changes necessitated by new information that has become available since its proposal. A conceptual grouping of the non-
Hodgkin
's lymphomas into four categories (indolent, aggressive, highly aggressive, and localized indolent) is also presented in this review. The next major impetus influencing the approach to lymphoma classification will no doubt be molecular genetics, in particular DNA microarrays, which will yield an enormous amount of new data that will aid in the understanding of lymphomas.
