    A 60 year old male presented with pruritus, excoriations and enlargement of several groups of lymph nodes associated with constitutional symptoms following the intake of an aspirin preparation. Lymph node biopsy established the diagnosis of angioimmunoblastic lymphadenopathy. The need to be aware of this condition is highlighted when patients present with clinical features suspicious of lymphoma.

    The significance of metastastic disease in the cervical lymph nodes has long been appreciated. The rich lymphatics of the upper aerodigestive tract explained the high incidence of cervical metastasis, occasional bilaterally spread. Even with appropriate treatment, cervical recurrences do occur. Nonetheless, with the resurgence of tuberculosis, the differential of tuberculous cervical lymphadenitis should be excluded. Appropriate modalities should be employed in making the appropriate diagnosis possible.

    BACKGROUND: The three standard biomarkers used in breast cancer are the estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2). The Ki-67 index, a proliferative marker, has been shown to be associated with a poorer outcome, and despite absence of standardization of pathological assessment, is widely used for therapy decision making. We aim to study the role of the Ki-67 index in a group of Asian women with breast cancer.

    MATERIALS AND METHODS: A total of 450 women newly diagnosed with Stage 1 to 3 invasive breast cancer in a single centre from July 2013 to Dec 2014 were included in this study. Univariable and multivariable logistic regression was used to determine the association between Ki-67 (positive defined as 14% and above) and age, ethnicity, grade, mitotic index, ER, PR, HER2, lymph node status and size. All analyses were performed using SPSS Version 22.

    RESULTS: In univariable analysis, Ki -67 index was associated with younger age, higher grade, ER and PR negativity, HER2 positivity, high mitotic index and positive lymph nodes. However on multivariable analysis only tumour size, grade, PR and HER2 remained significant. Out of 102 stage 1 patients who had ER positive/PR positive/HER2 negative tumours and non-grade 3, only 5 (4.9%) had a positive Ki-67 index and may have been offered chemotherapy. However, it is interesting to note that none of these patients received chemotherapy.

    CONCLUSIONS: Information on Ki67 would have potentially changed management in an insignificant proportion of patients with stage 1 breast cancer.

    Lymph node metastasis (LNM) in papillary thyroid cancer (PTC) has been shown to be associated with increased risk of locoregional recurrence, poor prognosis and decreased survival, especially in older patients. Hence, there is a need for a reliable biomarker for the prediction of LNM in this cancer. MicroRNAs (miRNAs) are small noncoding RNAs that regulate gene translation or degradation and play key roles in numerous cellular functions including cell-cycle regulation, differentiation, apoptosis, invasion and migration. Various studies have demonstrated deregulation of miRNA levels in many diseases including cancers. While a large number of miRNAs have been identified from PTCs using various means, association of miRNAs with LNM in such cases is still controversial. Furthermore, studies linking most of the identified miRNAs to the mechanism of LNM have not been well documented. The aim of this review is to update readers on the current knowledge of miRNAs in relation to LNM in PTC.

    Follicular dendritic cell sarcomas (FDCS) are rare neoplasms that involve lymph nodes or extranodal sites. They show varied histological features and thus can be mistaken for carcinoma or sarcoma. Correct identification is important for further management. A 43-year-old Indian female presented with a three-month history of progressive swelling at the right inguinal region. It was excised completely and was reported as lymph node with metastatic poorly differentiated carcinoma based on Haematoxylin and eosin (H&E) stain findings. Computerized tomography (CT) scans of thorax, abdomen and pelvis were normal and did not reveal a primary site. Following this, the case was referred to one of the authors. The slides were reviewed and a variety of immunocytochemical markers were done. The tumour cells were negative for epithelial, melanocytic, neural, leucocyte and soft tissue tumour markers. They were immunopositive for CD21, CD35 and negative for CD68. Based on the immunocytochemical findings, a final diagnosis of FDCS was made. This case highlights the histological and immunophenotypical profile of a rare tumour which requires a high index of suspicion for diagnosis.

    Angiofollicular lymphoid hyperplasia (Castleman's disease) is a lymphoproliferative process thought to be mediated by overexpression of II interleukin-6. Castleman's disease has two variants: Castleman's disease has two variants: Hyaline vascular type and plasma cell variant (multicentric Castleman's disease). The hyaline vascular type tends to be localized, and the plasma cell variant shows more systematic signs and carriers a worse clinical prognosis. Castleman's disease is associated with B-cell lymphoma, Kaposi sarcoma, Human herpes virus 8 (HHV-8), and Epstein-Barr virus. Castleman's disease have been described thrice post kidney transplant. In this report, we document the course of a renal recipient who developed the plasma cell variant of Castleman's disease at 16 months after failure of his allograft and return to dialysis. He displayed clinical resolution of this complication after graft nephrectomy. To our knowledge, this is the first case where the disease manifestations disappeared after graft removal. Our patient experienced chronic renal allograft rejection which may have driven all the systematic manifestations of multicentric castleman's disease and possibly reactivated a latent HHV-8 infection. In this case immunohistochemical testing for HHV-8 was not available to prove a role for this agent.

    Human dirofilariasis is a rare infection in Malaysia. Thus far, only two human cases have been reported viz. Dirofilaria immitis and D. (Nochtiella) repens and in both instances, adult worms were recovered from infected patients. The two cases reported in the present study, one from Melaka and the other from Penang, were diagnosed histologically. Based on the diagnostic criteria for identifying Dirofilaria in tissue sections, the parasites were identified as D. (Nochtiella) repens.

    An 86-year-old man presented with a painless, pea-sized growth over the left angle of his jaw, which had been gradually enlarging over two years. A clinical diagnosis of pilar cyst was made. Histopathological examination of the mass revealed a malignant proliferating trichilemmal tumour. During follow-up 4 months later, a palpable small upper jugular lymph node was noted at the left side of the neck. Biopsy revealed a metastatic malignant trichilemmal tumour. This case illustrates a rare malignant tumour which is a challenge to clinical diagnosis.

    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.

    OBJECTIVE: To assess the role of fine needle aspiration cytology (FNAC) in lymphadenopathy in human immunodeficiency virus-infected individuals (HIVII).

    STUDY DESIGN: Thirty-nine HIVII presenting with lymphadenopathy at University Hospital, Kuala Lumpur, were subjected to FNAC. Cytologic smears were routinely stained with May-Grünwald-Giemsa stain. Special stains and immunostains were used when necessary.

    RESULTS: In nine cases, the cytologic appearance was compatible with HIV type A and in one case with HIV type C lymphadenopathy. In 21 cases, acid-fast bacilli (AFB) were demonstrated in the cytologic smears, enabling a diagnosis of mycobacterial lymphadenitis. In one of these cases there was a concomitant infection with Penicillium marneffei that was overlooked on initial cytologic examination. The cause of granulomatous lymphadenitis could not be ascertained in one case, where neither AFB nor any other organisms were demonstrable. Two cases of histoplasma and one of cryptococcal lymphadenitis were diagnosed, as was one high grade non-Hodgkin's lymphoma that could be immunophenotyped on cytologic material. In three cases the aspirates were inadequate for a cytologic diagnosis.

    CONCLUSION: Lymph node FNAC is a valuable investigative modality in HIVII. Most opportunistic infections (bacterial and fungal) can be correctly identified, and high grade lymphoma can be diagnosed and phenotyped.

    BACKGROUND: Male breast cancer (MBC) is usually diagnosed at late stages and therefore has a worse prognosis than female breast cancer (FBC). MBC is also more likely to have lymph node (LN) involvement than FBC.

    MATERIALS AND METHODS: We sought to determine the prognostic role of the examined lymph node (LN), negative LN (NLN), and positive LN counts and the LN ratio (LNR), defined as (positive LNs/ENLs), on the survival rate among MBC patients. We performed a large population-based study using the data from the Surveillance, Epidemiology, and End Results program.

    RESULTS: Older age, black race, stage IV disease, ≤ 1 NLN, and a > 31.3% LNR were significantly associated with worse survival across all prediction models. Moreover, we demonstrated a decreased risk of mortality in MBC patients across the MBC-specific survival model (hazard ratio, 0.98; 95% confidence interval, 0.96-0.998; P = .03) and 10-year MBC-specific survival model (hazard ratio, 0.98; 95% confidence interval, 0.96-0.999; P = .04).

    CONCLUSION: MBC has had an augmented incidence over the years. We found several independent predictors of MBC survival, including age, race, stage, NLNs, and the LNR. We strongly suggest adding the NLN count and/or LNR into the current staging system. Further studies are needed to provide information on the mechanisms underlying the association between the NLN count and MBC survival and the LNR and MBC survival.

    Testicular cancer is an uncommon malignancy of the male reproductive organ, accounting for 1% of all cancers in men. Distant cervical metastasis from testicular cancer has been reported in 5% of patients. We present 2 cases of non-seminomatous testicular cancers that were diagnosed retrospectively in patients who presented with pure cervical lymph nodes. A comprehensive approach bearing in mind the possible differentials, pathogenesis and treatment options are discussed.
