Although eosinophilic granulocytes are frequently observed in lymphatic tissue of Hodgkin's patients, no substantial data reveal the prognostic role, if any, of tissue eosinophilia. Thus, eosinophilia was analyzed histologically in 1511 diagnostic biopsy specimens of patients treated under protocol therapy of the German Hodgkin's Lymphoma Study Group between 1988 and 1994. Prominent eosinophilia was seen in 38% of cases, which differed among the histologic types of Hodgkin's disease (HD): none in lymphocyte predominant, 14% in lymphocyte rich classical, 40% in nodular sclerosis grade 1 (NS-1), 55% in nodular sclerosis grade 2, 43% in mixed cellularity (MC), and 54% in lymphocyte depleted. In a multivariate analysis, tissue eosinophilia proved to be the strongest prognostic factor for freedom from treatment failure (P <. 001) and overall survival (P <.001) in a stage-stratified model. Among NS-1 patients, the effect was highly significant. In MC, no significant effect of eosinophilia on survival could be demonstrated. Eosinophils secrete CD30 ligand that is capable of binding to CD30 positive HD cells. The activation of TRAF2, followed by NF-kappaB, which occurs on CD30L/CD30 binding, may explain the neoplastic proliferation and apoptosis protection of HD cells. TRAF2 is also activated by EBV-LMP expression, which is detectable in the majority of MC but not NS cases. In addition to the possibility that eosinophils are only passive indicators for other unknown prognostic determinants, it may be concluded that the positive clinical outcome of eosinophilia-negative NS cases could be due to lower NF-kappaB activity.

We present the clinical and pathologic findings of a case of sclerosing mucoepidermoid carcinoma with eosinophilia of the thyroid in a 39-year-old woman. This particular case is notable because it initially presented as a cervical lymph node metastasis, and the initial clinical and histologic impression was Hodgkin disease, nodular sclerosis type. Sclerosing mucoepidermoid carcinoma with eosinophilia is a differentiated malignant neoplasm of the thyroid that can be confused with anaplastic carcinoma, medullary carcinoma, squamous cell carcinoma, or, as in this case, Hodgkin disease. A correct diagnosis of sclerosing mucoepidermoid carcinoma with eosinophilia involves awareness of this entity and appropriate immunohistochemical analysis. In this article, we briefly review the literature and stress the histologic and cytologic findings characteristic of sclerosing mucoepidermoid with eosinophilia of the thyroid.

Recent studies have analyzed the expression of chemokines in tissues involved by Hodgkin's disease (HD) (1). The data indicate a significant role for chemokine expression in the pathobiology and pathophysiology of HD. In general, HD tissues showed higher levels of chemokine expression than reactive lymphoid hyperplasia (RLH) tissues. There were major differences in chemokine expression among the different HD subtypes. Similar to previous studies in athymic mice that identified a pattern of chemokine response induced by Epstein-Barr virus (EBV)-infected cells, the expression of IP-10, Mig, RANTES, and MIP1-alpha was higher in EBV positive compared to EBV negative HD tissues. In addition, there was a direct correlation of eotaxin expression with tissue eosinophilia. By immunohistochemistry, IP-10 and Mig proteins localized in the malignant Reed-Steinberg (RS) cells and their variants, and to some surrounding inflammatory cells. Eotaxin localized to fibroblasts and smooth muscle of blood vessels. In this review, we discuss the patterns of expression of IP-10, Mig, RANTES, MIP1-alpha, and eotaxin in HD and its subtypes, and the relationship to EBV positivity, LMP1 expression, tissue eosinophilia and T cell infiltration. In addition, we discuss the potential role of chemokines and cytokines in the pathobiology of HD.

Although eosinophilic fasciitis (EF) may precede hematologic malignancy or Hodgkin's disease, association with peripheral T-cell lymphoma (PTCL) is extremely rare. Only four cases of EF preceding or concomitant PTCL have been reported in the world literature. We experienced the first Korean case of EF complicated by the later relapse of peripheral T-cell lymphoma. A 63-year-old Korean male has been followed at our outpatient clinic periodically after treatment for stage IV PTCL. He had been in complete remission for seven and a half years when he developed edema of both lower extremities followed by sclerodermatous skin change in both hands with peripheral eosinophilia. Biopsy from the left hand showed fibrous thickening of the fascia with lymphoplasmacytic and eosinophilic infiltrate, consistent with EF. Twenty-five months later, a newly developed lymph node from the left neck showed recurrence of PTCL. EF may occur as a paraneoplastic syndrome associated with the relapse of PTCL. Therefore, in a patient with EF, the possibility of coexisting and/or future occurrence of hematologic neoplasm should be considered.

Eosinophils frequently infiltrate tissues involved by Hodgkin's disease (HD), and blood eosinophilia is frequently observed. However, the clinical significance and the mechanisms underlying eosinophilia need further elucidation. In this study the grade of eosinophilic infiltration (EoI) was evaluated in biopsies from 259 HD-patients. In a selected group (n=32), the numbers of Hodgkin-Reed-Sternberg (HRS)-cells were counted, and the phenotype of small lymphocytes, the expression of cytotoxic lymphocyte-associated proteins, CD3-zeta-chain, HLA-DR, proliferation markers, latent membrane protein 1 (LMP-1) and blood lymphocyte function were evaluated. Samples from 88 HD patients (34%) showed high EoI. Significantly higher EoI was seen in nodular sclerosis 2 (NS2; p<0.001), bulky disease (p<0.05) and in patients <50 years (p<0.05). Patients with high EoI did not differ from the remainder with regard to distribution of sex, stage, B-symptoms, blood lymphocyte function and outcome. HRS-cells were significantly more frequent in NS HD as compared to mixed cellularity (MC) (p<0.001) irrespective of EoI. LMP-1-expression, proliferative fraction and phenotypes of small lymphocytes did not differ between the cases with low and high EoI, respectively. MC HD samples had significantly higher numbers of small cells positive for CD8 (p<0.01), T-cell intracellular antigen-1 (p<0.01) and Granzyme B (p<0.05) than NS. LMP-1-positive cases had significantly higher frequency of CD8-positive cells than LMP-1-negative. In conclusion, high EoI remains a feature of certain clinical subgroups of HD. However, there was no association between the degree of EoI and numbers of HRS-cells, phenotypes of small lymphocytes, EBV status and clinical outcome. Determination of EoI is of limited diagnostic and prognostic clinical value in HD. However, the differences in small cell distribution of CD8, TIA-1, GrB and CD57 between the histopathological groups and between LMP-1-expressing/non-expressing cases may contribute to our understanding of the biology of the disease.

A total of forty bone marrow trephine biopsies and aspirates were studied from thirty five patients suffering from Hodgkin's disease during the two year period 1994 and 1995. Of these twenty five were at the time of diagnosis of the disease and fifteen after treatment. The biopsies were studied for incidence of involvement as well as associated findings in both the positive and negative biopsies. A comparison of the trephine biopsy with marrow aspirate with respect to yield of positivity was made. Five patients (20%) at the time of diagnosis and two (13.33%) after treatment showed involvement of the marrow. None of the seven corresponding aspirates were positive for involvement showing that biopsies were superior to aspirates in detecting marrow infiltration in Hodgkin's disease. Suppression of the marrow, fibrosis and lymphocytic aggregates were the other findings in positive biopsies. Eosinophilia and myelosuppression were notable changes in the negative biopsies. One biopsy also showed granulomas. The probable significance of these findings are also discussed.

The prognostic value of histologic classification and single histomorphologic parameters in Hodgkin disease has been widely debated in the literature. Whereas several former studies identified single parameters to be of clinical relevance, some recent reports have doubted the prognostic value of histology using modern treatment. Grading of the largest histologic category of Hodgkin disease, nodular sclerosis (NS), has been controversially discussed concerning clinical relevance. In this study, 965 cases of NS were reviewed to assess 9 histomorphologic parameters. The histologic results were correlated with laboratory and clinical findings and with overall survival and disease-free survival. Based on these results, a new grading of the NS category was established. The new grading, based on the 3 criteria eosinophilia, lymphocyte depletion, and atypia of the Hodgkin/Reed-Sternberg cells, was a significant indicator of prognosis in intermediate and advanced stages. Patients investigated in this study represent an outstanding collection because all of them were enrolled in the prospective multicenter clinical trial of the German Hodgkin Lymphoma Study Group. All of them had been staged uniformly according to the Ann Arbor system and had received stage-adapted modern treatment according to multimodality protocols. A subtle analysis of histology could represent a possible way to identify patients with a significantly better or worse prognosis. This new grading should help to avoid overtreatment to reduce severe therapy-related side effects such as acute toxicity and chronic sequelae such as cardiopulmonary complications and secondary neoplasias.

Blood and tissue eosinophils can be associated with Hodgkin and non-Hodgkin lymphomas in that they have prognostic value. Tissue eosinophils in T-cell lymphoma patients with blood eosinophilia have not been systematically assessed. The objective of this research was to study the presence, density, and activation of tissue eosinophils in patients with primary cutaneous T-cell lymphomas (CTCLs) with blood eosinophilia and a possible relationship between features of the disease and prognosis. With skin biopsy specimens from 26 CTCL patients with blood eosinophilia, tissue eosinophils were studied with electron microscopy, extracellular eosinophil peroxidase deposits, and interleukin-5 expression. Tissue eosinophils, found in 22 of 26 cases, were constantly activated. Both density and activation of tissue eosinophils were significantly related to disease progression. The state of activation of tissue eosinophils in CTCL might reflect inflammatory flare-ups associated with aggressive lymphomas. Further studies are needed to confirm the value of eosinophil density as a simple and reliable marker of CTCL progression.

The authors report a case of Hodgkin lymphoma developing in a 4.5-year-old female child with hyper-IgE syndrome. This is one of the few cases of malignancy reported in this syndrome. The patient had severe atopic dermatitis, asthma, recurrent pneumonia, recurrent skin infections, and growth retardation. Immunologic evaluation revealed a high level of immunoglobulin E (7000 IU/mL) and peripheral eosinophilia. She was found to have normal values for serum IgG, IgM, IgA, WBC chemotaxis, serum complement function and normal sweat chloride test. The development of fatal Hodgkin lymphoma in this patient with hyper-IgE syndrome may suggest an increased risk for developing premature malignancies in hyper-IgE syndrome, although the precise immunologic defect is still unknown.

In this atypical case of sarcoidosis with an unusual combination of clinical and laboratory findings, a 32-year-old male presented with a 3-month history of thoracic pain complicated with dyspnea. Laboratory tests, chest radiography, and CT scans of the chest and abdomen revealed eosinophilia of pleural effusion and blood, pleural thickening, hepatosplenomegaly, and bronchiolitis obliterans. In cases such as this, in which pleural fluid eosinophilia is accompanied by peripheral eosinophilia and splenohepatomegaly, underlying malignancies such as Hodgkin lymphoma should be ruled out. A biopsy of the mediastinal lymph nodes suggested noncaseating epithelioid granulomas, characteristic of sarcoidosis. The patient underwent prednisolone therapy for 1 year and is doing well 2 years after initial diagnosis.
