J Helminthol, 1996 Sep;70(3):249-52.

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.

The expression statuses of sex steroid receptors and sex steroid-synthesizing/metabolizing enzymes have been reported in primary prostate cancer lesions, but that in metastatic lymph nodes has remained unknown. Therefore, in this study, we immunolocalized these proteins in primary tumors and paired metastatic lymph nodes of prostate cancer and correlated the findings with clinicopathological factors of individual patients. The expression statuses of AR and ER β was significantly increased in metastatic lymph nodes compared with primary lesions, whereas that of 17βHSD1, 17βHSD2, 17βHSD5, and STS immunoreactivity was decreased in metastatic lymph nodes. In metastatic lymph nodes, the status of 5α2 was significantly correlated with that of AR. In addition, 17βHSD5-, 5α1-, STS-, and EST-positive cases were significantly associated with Gleason score (GS) status (GS > 8 versus GS < 7) in metastatic lymph nodes. Results of our present study did demonstrate that in situ androgen and estrogen metabolism and action play roles in pathophysiology of prostate cancer in metastatic lymph nodes, but these steroidogenic effects could be different from those in primary lesions.

Detection and quantification of IgM(+) lymphocytes in fetal lamb spleen, liver and lymph nodes by flow cytometry

Alitheen N, McClure S, McCullagh P

Immunol Cell Biol, 2007 Jul;85(5):391-3.

PMID: 17515929

The first stage in Peyer's patch development in the fetal lamb is characterized by the colonization of the rudimentary Peyer's patches by precursor cells expressing the IgM surface receptor. In the fetal lamb, the spleen has been implicated as the source of gene-rearranged IgM(+) B lymphocytes. This study was intended to quantitate IgM(+) lymphocytes in the spleen, lymph nodes and liver of fetal lambs at various gestational ages between 63 and 110 days using flow cytometry. Flow-cytometric analysis revealed that IgM(+) lymphocytes were rare in the liver being consistently less than 1% at every gestational age examined. IgM(+) lymphocytes were detected in the spleen (mean 9.18%) and prescapular lymph nodes (mean 11.89%) as early as 63 days. In both spleen and lymph nodes, the highest representation of IgM(+) lymphocytes occurred between 70 and 86 days gestation. The highest mean percentage of IgM(+) lymphocytes was observed in the spleen (22.63%) and lymph nodes (17.02%) at 75 days gestation. From 98 days onwards, B-lymphocyte density gradually decreased in both spleen and prescapular lymph nodes. This study indicates that substantial populations of IgM(+) lymphocytes were present in both the spleen and prescapular lymph nodes from 70 days gestation and implies that both of these locations could be potential sources for the normal colonization of the ileal Peyer's patches.

Foreign body granuloma is a reaction to either a biodegradable substance or inert material. In a breast cancer patient who had undergone an excision or mastectomy with axillary clearance, a foreign body granuloma in the axilla may be misinterpreted as an axillary lymph node. We report our experience with a case of cotton-ball granuloma of the axilla in a breast cancer patient, which mimics a lymph node radiologically from the CT scan, mammogram and ultrasonography. Following biopsy and excision, the mass was diagnosed histologically as a foreign body granuloma.

Fulltext A child with epistaxis, reduced hearing and cervical lymphadenopathy: a rare case of nasopharyngeal carcinoma in a child

Muhammad Izani S, Irfan M, Suhaimi Y

Malays Fam Physician, 2011;6(2-3):82-4.

PMID: 25606231 MyJurnal

Although nasopharyngeal carcinoma (NPC) is common in this part of the world, the incidence among children is still very low worldwide. The diagnosis is sometimes delayed because of the late reporting of the symptom by the patient or parents, or difficulty in reaching the final diagnosis due to its hidden anatomical location. The challenges include the difficult endoscopy in children, inability to differentiate an adenoid from the tumour on radiograph and often the inconclusive fine needle aspiration findings. If the tumour mass at Fossa of Rosenmuller can be clearly appreciated and biopsied with undoubtedly proven histology of NPC, the diagnosis can be straight forward and treatment can be commenced as early as possible. We report a 10-year-old child presented with bilateral neck cervical lymphadenopathy and epistaxis with fine needle aspiration cytology (FNAC) of the neck mass reported as lymphoma. Further work-up confirmed he was suffering from NPC.

Thymic carcinoma is a rare thymic epithelial cancer which is not only locally invasive but also highly aggressive disease. The prognosis for this cancer is poor and the surgery remains the mainstay of treatment. Thymic carcinomas have been shown to metastasize to the lymph nodes, lung, and liver. A 63-year old male who was successfully treated for thymic cancer in 2015, presented with metastatic disease recurrence to the spinal cord. We share interesting images of the spinal cord lesions as well as pituitary metastases that were incidentally detected on restaging 18F-fluorodeoxyglucose positron emission tomography-computed tomography.

PMID: 34507605 DOI: 10.1186/s13104-021-05768-5

OBJECTIVE: Diffuse Large B Cell Lymphoma (DLBCL) is the most common type of Non-Hodgkin Lymphoma (NHL). The aim of this study was to assess the clinico pathological characteristics of DLBCL specifically, among the affected individuals residing in Northern areas of Pakistan who had not been previously included in major lymphoma studies due to their remote location.

RESULTS: Mean age of the patients was 49.7 years. Male: female ratio was 1.5:1. Primary site was lymph node in 99 (71.74%) patients, out of which, 36 (26.09%) patients had B symptoms and 19 (13.77%) patients had stage IV disease. 39 (28.26%) patients had primary extra nodal involvement, 4 (2.90%) patients had B symptoms and 3 (2.17%) had stage IV disease. Extra nodal sites involved in primary extra nodal DLBCL were gastrointestinal tract (GIT) 19 (48.72%), tonsils 6 (15.38%), spine 4 (10.26%), soft tissue swelling 3 (7.69%), parotid gland 2 (5.13%), thyroid 2 (5.13%) central nervous system (CNS) 1 (2.56), breast 1 (2.56%) and bone marrow 1 (2.56%). Our study revealed increased percentage of patients with nodal DLBCL in stage IV and with B symptoms. Few patients with primary extra nodal DLBCL had B symptoms and stage IV disease at presentation. GIT was the most common site of involvement in primary extra nodal DLBCL.

Fulltext The efficacy of pre-operative laparoscopy in the staging for gastric cancer

Kandasami P

International e-Journal of Science, Medicine & Education, 2012;6(Suppl 1):103-105.

MyJurnal

The only potential curative therapy for gastric cancer is the resection of both the tumor and the regional lymph nodes at the early stage of the disease. The majority of patients with gastric cancer in Malaysia have an advanced disease at initial diagnosis, and curative surgery is possible in less than 20% of operated cases. Acurate preoperative staging is crucial in determining the most suitable therapy and avoiding unnecessary attempts at curative surgery. While computed tomography remains as the most widely used imaging modality for gastric cancer staging, its ability to detect local invasion, peritoneal and liver metastases is limited. In the recent years laparoscopy has become an important component in the staging algorithm of gastric cancer. The aim of this review is to evaluate the efficacy of routine preoperative laparoscopic staging in the management of gastric cancer, and in particular describe the Malaysian experience.

Fine needle aspiration cytology under radiologic guidance for diagnosis of renal cell carcinoma is well established and is increasingly utilized. This is because renal cell carcinoma displays fairly characteristic cellular features permitting correct cytologic identification. We present a case of a 66-year-old man who had advanced renal cell carcinoma with spread to aortic and cervical lymph nodes, lungs and liver. Fine needle aspiration cytology of the para-aortic mass showed tight clusters of malignant cells with abundant and vacuolated cytoplasm consistent with renal cell carcinoma. Histology of the left cervical lymph nodes together with immunohistochemistry findings were consistent with the cytologic diagnosis of metastatic renal cell carcinoma. The patient succumb to his illness three years after the diagnosis was made.

International e-Journal of Science, Medicine & Education, 2009;3(2):-.

MyJurnal

Gestational breast cancer (GBC) or pregnancy-associated breast cancer was defined as breast cancer diagnosed during pregnancy and within 1 year of delivery. Breast cancer is the second commonest cancer after cervical seen in pregnancy and lactation. Nevertheless, the incidence is low and accounts for approximately 1 in 3000 of pregnancies. A delay in diagnosis is common and 70% to 89% of patients with operable primary lesions already have positive axillary lymph nodes. Breast cancer identified during pregnancy can be extremely distressing for the mother despite it has similar course of disease and prognosis seen in non-pregnant women of the same age and stage of disease. Diagnostic and treatment options should be carefully decided to prevent further harm to the mother or any potential risk to the developing fetus.

PMID: 25606258 MyJurnal

Neck mass is a common condition in primary care. The most common affected area is the cervical lymph node. The neck region is also prone infection as structurally the nodes and spaces are in close contact with the upper respiratory tract and the alimentary tract. Oral cavity is one of the most common route for harbouring infection. Poor oral hygeine and periapical dental problems are the main causes. Thus, it is important to perform a complete oral cavity examination even when trismus is present. Besides dental caries, floor of the mouth should be inspected for oedema that may impose threat to the upper airway. We report a case of Ludwig's angina originating from a periapical lesion of the lower molar stressing the importance of oral examination in patient with neck mass.

Fulltext Neuroendocrine carcinoma of tonsil presented with axillary lymph node metastasis: Management dilemma

Kamarudin Z, Jamaluddin N, Latar NHM, Pauzi SHM, Muhammad R

J Cancer Res Ther, 2023 Oct 01;19(7):2104-2107.

PMID: 38376332 DOI: 10.4103/jcrt.jcrt_1506_21

High-grade neuroendocrine carcinoma (NEC) of the tonsil is rare and has a poor prognosis. The usual presentation is a neck mass with locoregional cervical lymphadenopathy. An axillary lymphadenopathy as a primary presentation of NEC of the tonsils is uncommon and challenging to treat. Tonsil neuroendocrine tumors display aggressive behaviors associated with early recurrence and metastasis after surgical resection. Managing this condition is demanding compared to NECs of gastrointestinal origin since, to date, the management of head-and-neck neuroendocrine tumors is still not well established. We present a 49-year-old female with a rare case of NEC of the tonsil presenting primarily with axillary lymph nodes metastasis. The patient's axillary lymph node was biopsied and revealed a Grade III neuroendocrine tumor. A positron emission tomography (PET) scan was done in searching of a primary lesion and showed a highly metabolic mass of the left tonsil as well as a left axillary lymph node suggestive of metastasis. The patient has been managed with a multimodality approach, with a combination of chemotherapy regimen and surgical resection of the axillary lymph node. Subsequent PET scan evaluation showed a complete response of the primary tumor with residual left axillary lymph node metastasis. NECs of tonsil presented with axillary lymph nodes metastasis is rare and has a poor prognostic outcome. It poses a dilemma with regard to management, as surgical resection of the metastasis is not promising given the possibility of early recurrence.

Follicular dendritic cell sarcoma of inguinal lymph node--a case report

Pailoor J, Iyengar KR, Chan KS, Sumithra S

Malays J Pathol, 2008 Dec;30(2):115-9.

PMID: 19291921

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.
