Twelve patients (eight men and four women) had previously undiagnosed lymphoreticular disease associated with or simulating an inguinal (nine) or femoral (three) hernia. The disease was present on the left side in eight. Four patients (three women and one man) did not have an actual hernia. Two of these women had a preoperative diagnosis of femoral hernia. Seven of the patients, including all of the women, had non-Hodgkin's lymphoma (three diffuse large cell, two follicular mixed cell and two follicular small cleaved cell) and one patient had lymphocytic predominance (nodular lymphocytic and histiocytic) Hodgkin's disease. No stage predominated. Inguinal lymph nodes from two patients showed, histologically, Kaposi's sarcoma and type I human immunodeficiency virus (HIV) associated disease. Each patient was homosexual and HIV seropositive. Changes suggestive of viral cause were present in the lymph node of one patient. The enlarged lymph nodes of the 12th patient showed stellate suppurative granulomas containing cat-scratch bacilli demonstrated by Warthin-Starry stain. Because of the special processing needs for lymphoreticular diseases and potential for misdiagnosis, surgeons, clinicians and pathologists should be aware of the spectrum of lymphoreticular processes occurring in lymph nodes associated with or masquerading as a hernia, particularly in women.

Indirect fluorescent antibody assay (IFA) is the most reliable test for detecting antibody to Bartonella henselae in the diagnosis of cat scratch disease (CSD). Recently, an ELISA test has been proposed, but conflicting results are reported. We compared IgG-IFA and IgG-IgM ELISA methods in CSD patients and in healthy children. We also tested ELISA specificity in a large group of healthy controls and in children with lymphoma-associated lymphadenopathy and with pyogenic lymphadenitis. The ELISA procedure was positive in 69/78 patients with CSD (sensitivity 89.6%), in 5/100 healthy children (specificity 95%), in 2/51 patients with non-Hodgkin's lymphoma or pyogenic lymphadenitis (specificity 96%) and in 27/296 blood donors (specificity 91.6%). In 34 patients with CSD, ELISA IgM and IgG responses decreased significantly between time of diagnosis of the disease and recovery. We found significantly higher IgG-ELISA titres in cat-owners, whether blood donors or healthy children, than in non-cat-owners. The IgG-IFA test gave positive results in 69/78 patients with CSD (sensitivity 89.6%) and in 5/62 healthy controls (specificity 92.5%). The ELISA method is a cheap, sensitive method for determining antibody response to Bartonella henselae infection and is also important for evaluating the clinical course of the disease and the efficacy of antibiotic therapy. The high specificity of ELISA in patients with non-Hodgkin's lymphoma will help the clinician to exclude a potentially life-threatening disease associated with lymphadenopathy.

Lymph node excision biopsy is commonly carried out for the investigation of lymphadenopathy. The objective of this study is to elucidate the pattern of nodal pathology seen in a private pathology practice. A total of 137 nodal biopsies for primary investigation of nodal enlargement were retrieved from the files in a private diagnostic pathology laboratory in the year 1997. Lymph nodes excised for cancer staging were excluded from this study. The histology was reviewed based on H&E stained sections, and with additional histochemical and immunoperoxidase stains when deemed necessary. Cases of malignant lymphomas were sub-classified with the aid of further immunophenotyping using a panel of monoclonal and polyclonal lymphoid antibodies. One case was excluded from this study due to inadequate tissue for further assessment. There were 58 males and 78 females, giving a ratio of 1:1.3 in the remaining 136 cases. They consisted of 13 Malays (M), 108 Chinese (C), 14 Indians (I) and 1 other ethnic group (O). The ratio of M:C:I:O was 1:8.3:1.1:0.1. The majority of the cases were in the age range of 20 to 50 years. The pathology consisted of 17 (12.5%) malignant lymphomas [6 Hodgkin's lymphoma, 11 non-Hodgkin's lymphoma], 35 (25.7%) metastatic carcinomas, 45 (33.1%) reactive hyperplasia, 19 (13.9%) tuberculosis, 11 (8.2%) Kikuchi's disease and 9 (6.6%) others (Castleman's disease 2, cat scratch disease 2, Kimura's disease 1, sarcoidosis 1, non-specific lymphadenitis 3). All categories of nodal disease showed approximately similar ratio of ethnic and gender distribution as above, except for Kikuchi's disease, for which 100% of the patients were female. The most common site of biopsy was from the head and neck region, particularly the cervical group of nodes. The most common nodal pathology seen in the private laboratory was reactive hyperplasia, followed by metastatic carcinoma. Malignant lymphoma constituted only 12.5% of the cases.
