Micobacterias atípicas en cinco pacientes adultos sin evidencias de inmunosupresión: Construyendo una experiencia / Atypical mycobacterial infections in five adult patients without evidence of immunosuppression: Making an experience

We aim to communicate the experience gathered during the management of infections by atypical mycobacteria in immunocompetent patients in a general practice. Between 2008 and 2013, 5 patients with non-tuberculous mycobacterial infections were identified: 2 with cutaneous involvement and 3 with lung infection. None of them had evidence of immunosuppression. A patient with elbow bursitis by M. chelonae presented with a high mononuclear count in fluid analysis with mycobacterial growth at the fifth day of culture. He evolved satisfactorily with clarithromycin. A case with M. fortuitum skin infection had a delayed initial diagnosis with progression to local draining lymph nodes; the culture when requested was positive after 13 days of incubation. Patients with pulmonary infection presented with prolonged cough and sputum and had in common to be postmenopausal women displaying small nodules and bronchiectases at lung images, a classical pattern. Time elapsed between respiratory sampling and a definitive inform ranged from 40 to 89 days. Non-tuberculous mycobacterial infections in non-immunosuppresed patients can generate diagnostic and therapeutic challenges. Delay in identification contributes to this problem.

El objetivo de este trabajo es reportar la experiencia acumulada sobre infecciones por micobacterias atípicas en pacientes sin inmunosupresión. Entre el año 2008 y 2013 se observaron cinco pacientes con infección por micobacterias atípicas: dos con infección cutánea y tres con infección pulmonar. Ninguno de estos pacientes tenía evidencias de inmunosupresión. Un paciente con bursitis de codo por M. chelonae tuvo un estudio citoquímico con aumento de celularidad de predominio mononuclear y desarrollo de bacterias al quinto día; respondió favorablemente a claritromicina. Un caso con infección cutánea por M. fortuitum evolucionó en forma prolongada con supuración ganglionar antes del diagnóstico y el cultivo solicitado a los 13 días fue positivo. Los tres pacientes con aislados pulmonares presentaron tos y expectoración y tenían en común ser mujeres en edad post-menopáusica y presentar pequeños infiltrados nodulares asociados a bronquiectasias en el estudio de imágenes pulmonares, un patrón descrito en la literatura científica. En estos tres casos, la latencia entre la toma de muestra y el informe definitivo tuvo un rango de 40 a 89 días. El aislamiento de micobacterias atípicas en muestras de expectoración en pacientes sin inmunosupresión se da en un contexto típico pero plantea dificultades diagnósticas y terapéuticas. El lento crecimiento de estos microorganismos en el laboratorio contribuye a este problema.

Clinical Value of Endobronchial Ultrasound Findings for Predicting Nodal Metastasis in Patients with Suspected Lymphadenopathy: A Prospective Study

We evaluated whether sonographic findings can provide additional diagnostic yield in endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), and can more accurately predict nodal metastasis than chest computed tomography (CT) or positron emission tomography (PET)/CT scans. EBUS-TBNA was performed in 146 prospectively recruited patients with suspected thoracic lymph node involvement on chest CT and PET/CT from June 2012 to January 2013. Diagnostic yields of EBUS finding categories as a prediction model for metastasis were evaluated and compared with findings of chest CT, PET/CT, and EBUS-TBNA. In total, 172 lymph nodes were included in the analysis: of them, 120 were malignant and 52 were benign. The following four EBUS findings were predictive of metastasis: nodal size > or =10 mm, round shape, heterogeneous echogenicity, and absence of central hilar structure. A single EBUS finding did not have sufficient diagnostic yield; however, when the lymph node had any one of the predictive factors on EBUS, the diagnostic yields for metastasis were higher than for chest CT and PET/CT, with a sensitivity of 99.1% and negative predictive value of 83.3%. When any one of predictive factors is observed on EBUS, subsequent TBNA should be considered, which may provide a higher diagnostic yield than chest CT or PET/CT.

Bronchial Anthracofibrosis and Macroscopic Tissue Pigmentation on EBUS-TBNA Predict a Low Probability of Metastatic Lymphadenopathy in Korean Lung Cancer Patients

The identification of mediastinal lymph nodes (LNs) in lung cancer is an important step of treatment decision and prognosis prediction. The endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is widely used to assess the mediastinal LNs and tissue confirmation in lung cancer. As use of bronchoscopy or EBUS-TBNA has been increased, bronchial anthracofibrosis (BAF) has been detected frequently. Moreover, BAF is often accompanied by mediastinal lymphadenopathy and showed false-positive positron emission tomography uptake, which mimics metastatic lymphadenopathy in lung cancer patients. However, clinical implication of BAF during bronchoscopy is not well understood in lung cancer. We retrospectively reviewed 536 lung cancer patients who performed EBUS-TBNA and observed BAF in 55 patients. A total of 790 LNs were analyzed and macroscopic tissue pigmentation was observed in 228 patients. The adjusted odds ratio for predicting malignant LN was 0.46 for BAF, and 0.22 for macroscopic tissue pigmentation. The specificity of BAF and macroscopic tissue pigmentation for predicting a malignant LN was 75.7% and 42.2%, respectively, which was higher than the specificity of using LN size or standard uptake value on PET. In conclusion, BAF and macroscopic tissue pigmentation during EBUS-TBNA are less commonly found in malignant LNs than reactive LNs in Korean lung cancer patients.

Punção aspirativa guiada por ultrassom endobrônquico no diagnóstico e estadiamento de linfadenopatia mediastinal: experiência inicial no Brasil / Endobronchial ultrasound-guided transbronchial needle aspiration in the diagnosis and staging of mediastinal lymphadenopathy: initial experience in Brazil

OBJETIVO: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA, punção aspirativa por agulha guiada por ultrassom endobrônquico) é um método novo em diagnóstico e estadiamento linfonodal mediastinal. O objetivo do estudo foi avaliar os resultados preliminares obtidos com EBUS-TBNA no diagnóstico de lesões e no estadiamento linfonodal mediastinal. MÉTODOS: Foram avaliados pacientes com tumores ou adenopatias mediastinais e com diagnóstico ou suspeita de câncer de pulmão. Os procedimentos foram realizados com os pacientes sob sedação ou anestesia geral. O material coletado foi preparado em lâminas fixadas em álcool absoluto para citologia e em formol para bloco de células. RESULTADOS: Foram incluídos 50 pacientes (30 do sexo masculino), com média de idade de 58,3 ± 13,5 anos. Foram realizadas 201 punções em 81 linfonodos ou massas mediastinais (média de 2,5 punções). O material obtido foi considerado adequado para análise citológica em 37 pacientes (74 por cento), dos quais 21 (57 por cento) foram diagnosticados com malignidade. Nos 16 pacientes remanescentes, 1 teve diagnóstico de tuberculose, 6 tiveram seguimento clínico, e 9 foram submetidos a investigação adicional (2 diagnosticados com neoplasia - resultados falso-negativos). O rendimento do exame foi maior nos procedimentos com objetivo diagnóstico, em pacientes com lesões em múltiplas estações, e nas punções da estação linfonodal subcarinal. Um paciente apresentou sangramento endobrônquico resolvido com medidas locais. Não houve mortalidade na série. CONCLUSÕES: Esta experiência preliminar confirmou que o EBUS-TBNA é procedimento seguro, e que o nosso rendimento diagnóstico, inferior ao da literatura, foi compatível com a curva de aprendizado do método.

OBJECTIVE: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a new method for the diagnosis and staging of mediastinal lymph nodes. The objective of this study was to evaluate the preliminary results obtained with EBUS-TBNA in the diagnosis of lesions and mediastinal lymph node staging. METHODS: We evaluated patients with tumors or mediastinal adenopathy, diagnosed with or suspected of having lung cancer. The procedures were performed with the patients under sedation or under general anesthesia. Material was collected by EBUS-TBNA, after which it was prepared on slides, fixed in either absolute alcohol (for cytology) or formalin (for cell-block analysis). RESULTS: We included 50 patients (30 males). The mean age was 58.3 ± 13.5 years. We performed 201 biopsies of 81 lymph nodes or mediastinal masses (mean of 2.5 punctures/biopsy). The quantity of material was considered sufficient for cytology in 37 patients (74 percent), 21 (57 percent) of whom were thus diagnosed with malignancy. Of the remaining 16 patients, 1 was diagnosed with tuberculosis, 6 entered clinical follow-up, and 9 underwent further investigation (2 diagnosed with neoplasm-false-negative results). The yield was higher when the procedure was performed for diagnostic purposes, as well as being higher in patients with lesions in multiple stations and in biopsies involving the subcarinal lymph node station. One patient had endobronchial bleeding, which was resolved with local measures. There were no deaths among the patients evaluated. CONCLUSIONS: This preliminary experience shows that EBUS-TBNA is a safe procedure. Our diagnostic yield, although lower than that reported in the literature, was consistent with the learning curve for the method.

Role of Imprint Cytology in Diagnosis of Lymph Node Lesions.

Introduction: Imprint cytology is proved to be rapid inexpensive tool in the diagnosis of various lymph node lesions. Objective: The present study was conducted to correlate the diagnostic accuracy, sensitivity and specificity of imprint cytology of various lymph node lesions with histopathological diagnosis. 102 cases were included in the study comprising inflammatory lesion, tubercular lymphadenitis, lymphomas and metastatic carcinomas. Material and Method: From 102 cases of lymph node excision, imprint smears were taken and stained with Hematoxylin & Eosin and Papanicolaou stains. The findings of imprint cytology were then compared with final histopathological diagnosis. Result: When compared with final histopathological diagnosis, imprint smears showed overall diagnostic accuracy of 97.8% with sensitivity and specificity of 95.05% and 98.69% respectively. Accuracy rate for metastatic lymphadenopathy was 100%, whereas, for tubercular lymphadenitis it was 98.04% and for lymphomas 96.04%. Conclusion: Imprint cytology proved to be very useful for diagnosis of metastatic tumour as it gave 100% diagnostic accuracy, sensitivity and specificity. Imprint cytology is also considered to be useful in superficial ulcers to differentiate between benign and malignant lesions without surgical intervention.

clinicomorphological study of lymphadenopathy

A total 238 lymph nod specimen were studied at various Hospitals of Lahore. The ages of these patients ranged from 2 years to 80 years. Maximum number of patients with lymphadenopathy [90 out of 238] 37.8% cases were in 10-19 years age group. Females [51.7%] presenting with lymph node enlargement were more affected than males [48.3%]. The commonest presenting complaint was fever [56.3%]. Cervical lymph nodes [80.3%] were the commonest site of involvement. On histopathological examination, seven morphological groups were highlighted; tuberculous lymphadenitis [42.5%], chronic nonspecific lymhadenitis [36.6%], viral lymphadenitis [3.4%] acute bacterial lymphadenitis [0.8%]. Fungal lymphadenitis [0.8%], Metastatic carcinoma [11.3%] and lymphomas [4.6%]

A rare case of sarcoid-like reaction of lymph nodes associated with squamous cell carcinoma of alveolar mucosa.

Non-necrotizing granulomas are occasionally seen in patients with certain malignant disorders and are termed as "sarcoid-like reaction," which have many similarities with sarcoidosis. Sarcoidosis is a multisystem granulomatous disease of unknown etiology characterized by organ involvement and interference of organ function by granuloma or fibrosis. Sarcoidosis is occasionally found in a variety of malignant diseases with an overall incidence of 4.4% in carcinoma patients. We present here a rare case of moderately differentiated squamous cell carcinoma of alveolar mucosa with regard to mandible associated with sarcoid-like reaction of cervical lymph nodes in a female patient in the absence of clinical evidence of systemic sarcoidosis. The relevant literature including pathogenesis is also discussed.

Histopathologic findings of lymph node biopsy cases in comparison with clinical features

To determine useful and important clinical signs and symptoms for evaluation of lymphadenopathy with consideration of histopathologic findings of biopsy. This retrospective case-series study was done on patients hospital folders who came with lymphadenopathy, Informations was collected about clinical signs, symptoms, age, gender and histopathologic findings. It was then analyzed by SPSS version 13 with chi-square test. There were 208 specimens, 98 women [47.1%] and 110 men [52.9%]. Mean age was 32.94 years. There were 45 cases [21.6%] of malignancy, 33 cases [15.9%] of infectious diseases and 130 cases [62.5%] of reactive lymphadenopathy. The most common histopathologic finding in all ages was reactive lymphadenopathy. Clinical signs and symptoms had significant relationship with pathologic findings. For a decision of lymph node biopsy attention to patients symptoms and signs especially B signs, size of the lymph node >2cm, generalized lymphadenopathy, mobility of lymph node and splenomegaly seems to be the useful guide lines for physician. In this study it seems that decision to take biopsy was correct in 75% of the cases

clinicomorphological study of non-neoplastic lymphadenopathy

The Clinico Morphological Changes in 150 Cases of Non-neoplastic lymph adenopathy were studied at BMC Complex Hospital Quetta. The ages of these patients ranged from 2 years to 80 years. Maximum number of patients with lymphadenopathy [65 out of 150] 43.3% cases were in 11-20 years ago group. Females [56%] presenting with lymph node enlargement were more affected than males [44%]. The commonest presenting complaint was fever [67%]. Cervical lymph nodes [82.6%] were the commonest site of involvement. On histopathological examination, four morphological groups were highlighted; tuberculous lymphadenitis [50%], chronic non-specific lymhadenitis [44%], viral lymphadenitis [4%] acute bacterial lymphadenitis [2%]. The study also highlights the yield of Mycobacteria on fluorescent staining as highly significant [P<0.001] as compared to Ziehl-Neelsen staining, there by proving the superiority of fluorescent stain

Crianças com linfadenopatia cervical significativa: análise clínico-patológica e papel da aspiração por agulha fina no contexto indiano / Children with significant cervical lymphadenopathy: clinicopathological analysis and role of fine-needle aspiration in Indian setup

OBJETIVO: Estudar o perfil clínico-patológico de crianças indianas com linfadenopatia cervical e o papel da citologia aspirativa por agulha fina com ênfase especial na tuberculose como causa. MÉTODOS: Foram incluídas 89 crianças com faixa etária de 10 meses a 12 anos, admitidas em nosso hospital de abril de 2004 a março de 2005. Todos os pacientes foram submetidos a completa avaliação clínica e investigativa em relação à linfadenopatia cervical. Medidas de desfecho incluíram estado clínico e a capacidade de testes convencionais em categorizar tipos diferentes de linfadenopatia e sua utilidade no diagnóstico de linfadenite tuberculosa. A variabilidade interobservador foi analisada através do teste de kappa, tendo boa concordância. RESULTADOS: A hiperplasia reativa foi o tipo mais comum de linfadenite, seguida da granulomatosa. Os linfonodos do triângulo posterior unilateral foram o grupo afetado com maior freqüência no grupo de linfadenopatia cervical tuberculosa. A aspiração por agulha fina, seguida da coloração de Ziehl-Neelsen, histopatologia e cultura em associação, obteve sucesso em realizar o diagnóstico em 85,7 por cento dos casos de etiologia tuberculosa. CONCLUSÕES: A aspiração por agulha fina é uma ferramenta diagnóstica valiosa no tratamento de crianças com apresentação clínica de linfonodos cervicais aumentados. A técnica reduz a necessidade de procedimentos mais invasivos e dispendiosos, principalmente em países em desenvolvimento.Cultura e histopatologia, entretanto, devem ser consideradas em casos nos quais a citologia aspirativa por agulha fina não é diagnóstica.

OBJECTIVE: To study the clinicopathological profile of children from India with cervical lymphadenopathy and the role of fine-needle aspiration cytology with special emphasis on tuberculosis as a cause. METHODS: A total of 89 children in the age group of 10 months to 12 years, presenting to our hospital from April 2004 to March 2005, were included. All the patients underwent thorough clinical and investigational assessment vis-à-vis cervical lymphadenopathy. Outcome measurements included clinical status and ability of conventional tests to categorize different types of lymphadenopathy and their utility in diagnosing tubercular lymphadenitis. Interobserver variability was analyzed measuring kappa test and was found to be in agreement. RESULTS: Reactive hyperplasia was the most common type of lymphadenitis, followed by granulomatous involvement. Unilateral posterior triangle lymph nodes were the most commonly affected in the tubercular cervical lymphadenopathy group. Fine-needle aspiration followed by Ziehl-Neelsen staining, histopathology and culture in combination were able to perform the diagnosis in 85.7 percent of cases affected with tubercular etiology. CONCLUSIONS: Fine-needle aspiration is a valuable diagnostic tool in the management of children with the clinical presentation of enlarged cervical lymph nodes. The technique reduces the need for more invasive and costly procedures, especially in a Third World country. Culture and histopathology, however, should be considered in cases where repeated fine-needle aspiration cytology is non-diagnostic.

Histomorphological study of lymphoid follicle of vermiform appendix.

The study was done to find out the number of lymphoid follicle of vermiform appendix in Bangladeshi people and to increase the knowledge regarding variational anatomy in our population. Total 40 fresh appendixes were collected for histological study of different age and sex during postmortem examination in the autopsy laboratory of Forensic department of Mymensingh Medical College. This cross sectional descriptive study was done by convenient sampling technique. For convenience of differentiating the number of lymphoid follicle of vermiform appendix in relation to age and sex, findings were classified in four groups, up to 20 years, 21 to 35 years, 36 to 55 years and 56 to 70 years. In the present study the number of lymphoid follicle were highest in group A, mean were (5.40+/-1.30) and lowest in group D where mean were (1.05+/-0.35). In male mean were 3.16 and in female mean were 2.86. Diameter of the lymphoid follicle in group A was highest (40.14+/-2.66) and lowest in group D (0.24+/-1.35). Number of germinal centre are highest in group B (2.20 +/- 0.45) and lowest in group D (0.00 +/- 0.00).

Diagnostic yield of transbronchial needle aspiration in intrathoracic lymphadenopathy

Transbronchial needle aspiration [TBNA] is a safe and effective technique for the diagnosis of mediastinal lesions. The aim of this study was to evaluate diagnostic yield of TBNA in patients with benign and malignant lesions involving mediastinal and hilar lymph nodes. TBNA procedures were performed using a flexible bronchoscope and a 22-gauge cytologic needle in 22 patients with mediastinal or hilar adenopathy identified on CT of the chest. Based on the clinical diagnosis or presence of endobronchial lesions, other procedures such as bronchoalveolar lavage, bronchial biopsy, and transbronchial lung biopsy were performed Among 22 patients with a mean age of 50 +/- 18 years, 13 were males [59%] and 9 were females [41%]. Adequate lymph node samples were obtained in 16 patients [72.7%]. Among 9 patients with malignancy, TBNA provided diagnostic results in 5 patients [55.5%]. TBNA provided adequate specimen in 10 out of 13 patients with sarcoidosis, but in 2 patients [15.4%] diagnosis was made by TBNA. Overall, TBNA yield was 31.8%. There was no complication during TBNA procedures. TBNA is a minimally invasive technique for diagnosis of intrathoracic lymphadenopathy, especially in malignant diseases. The procedure also can be used as a diagnostic tool in patients with sarcoidosis, although the yield is low

Tuberculose do timo / Tuberculosis of the thymus

Os tumores do mediastino anterior incluem várias entidades com diferentes manifestações radiológicas e clínicas, consistindo em um grupo heterogêneo de condições congênitas, inflamatórias ou neoplásicas. Entre essas lesões, o tumor primário mais comum do mediastino é o timoma, seguido de perto por tumores de células germinativas e linfomas. A tuberculose do timo é extremamente rara, embora o envolvimento dos linfonodos mediastinais por essa entidade seja comum. Apresentamos aqui achados patológicos, radiológicos e clínicos de um caso de tuberculose tímica em um paciente de 18 anos de idade, que apresentou dor torácica, dispnéia a pequenos esforços e piora contínua dos sintomas em uma semana. A radiografia torácica mostrou uma grande massa no mediastino e a tomografia computadorizada mostrou que a localização era anterior. O paciente foi operado, sendo feita a exérese da massa, com aspecto microscópico de uma reação inflamatória maciça e presença de granulomas no tecido tímico. A pesquisa de bacilos álcool ácido resistentes pelo método de Ziehl-Neelsen foi positiva e o diagnóstico de tuberculose foi fechado. Portanto, o cirurgião e o patologista devem estar alertas quanto à essa entidade, bem como incluí-la na lista de diagnósticos diferenciais de massas mediastinais.

Tumors of the anterior mediastinum include several entities with different radiological and clinical manifestations, constituting a heterogeneous group of congenital, inflammatory, and neoplastic conditions. Among these lesions, the most common primary tumor of the mediastinum is thymoma, nearly followed by germ cell tumors and lymphomas. Tuberculosis of the thymus, an extremely rare condition, typically involves Qthe mediastinal lymph nodes. We present, in this study, pathological, radiological, and clinical findings of one case of tuberculosis of the thymus in an 18-year-old patient who presented thoracic pain, dyspnea upon minimal effort, and progressive worsening of the symptoms in one week. The chest X-ray showed a large mass in the mediastinum, and computed tomography scans indicated that it was located anteriorly. The patient was submitted to surgery in order to excise the mass. Microscopy revealed a massive inflammatory response and granulomas in the thymic tissue. Ziehl-Neelsen staining for acid-fast bacilli yielded positive results, and a diagnosis of tuberculosis was made. Surgeons and pathologists should remain alert for this condition and should include it in the differential diagnosis of mediastinal masses.

Sinus histiocytosis with massive lymphadenopathy--a review of seven cases.

Sinus histiocytosis with massive lymphadenopathy (SHML) also called as Rosai Dorfman disease is a rare histiocytic proliferative disorder of unknown etiology. Histological features currently define it. Persistent painless lymphadenopathy due to expansion of sinuses infiltrated with benign histiocytes and plasma cells and emperipolesis are the characteristic features of SHML. Our study includes seven cases (5 nodal and 2 extranodal) of SHML over a 5-year period whose slides and blocks were reviewed. IHC was performed on the main lesion, from a panel of S100, CD68, LCA, CD20, CD3, CD30, CD43, bcl2, cytokeratin and epithelial membrane antigen. In our series we have work up available in 7 cases out of which a detailed follow-up is available in 5 patients. Out of these 5 patients, 4 have a stable disease, while one developed histiocytic sarcoma after a gap of four years.

Diagnostic value of fine needle aspiration cytology [FNAC] in cervical lymphadenopathy

The aim of this study was to evaluate the diagnostic value of fine needle aspiration cytology [FNAC] in head and neck lymph nodes and in differentiating malignant from benign diseases. This prospective study was conducted in the ENT Department of PGMI HMC and LRH Peshawar from 1st April 2003 to 30th March 2004. A total of 42 patients were studied. After thorough history and examination, FNA biopsy was obtained with the help of experienced cytopathologist using 21G needle and the results compared with final histopathological diagnosis. FNAC findings in this series were metastatic [42.85%], tuberculosis adenitis [26.19%], reactive hyperplasia [16.66%], lymphoproliferative disorder [9.52%] and lymphoma [4.76%]. In terms of differentiating malignant from non-malignant lesions; diagnostic accuracy, sensitivity, speciflcity, positive predictive value and negative predictive value of FNAC were 95.23%, 95.83%, 94.44%, 95.85% and 94.44% respectively. FNAC has been found to be a useful diagnostic tool in the evaluation of patients presenting with neck nodes and should be considered before performing open biopsy

Sinus histiocytosis with massive lymphadenopathy (Rosai Dorfman disease): evidence for a dendritic cell derivation?

Sinus histiocytosis with massive lymphadenopathy or Rosai-Dorfman disease is a rare histiocytic disorder of unknown origin. Both dendritic cell and monocyte-macrophage lineage have been considered as the origin of the histiocytes that are classical of the disorder. We analyzed seven cases of Rosai-Dorfman disease to determine the immunophenotypic profile of these cells. Immunohistochemical analysis was undertaken by using: (a) fascin as a novel mature dendritic cell marker; (b) S-100 protein; (c) CD68 (both KP1 and PGM1) as macrophage related markers; (d) CD79a and (e) CD3. The Rosai-Dorfman histiocytes exhibited strong cytoplasmic staining for fascin in all the cases and demonstratedformation of a meshwork of fine dendritic processes emanating from the cell cytoplasm. S-100 protein was uniformly expressed in all the cases. Expression of both KP1 and PGM1 epitopes of CD68 was found to be weak and variable. The phagocytosed lymphocytes were composed of an admixture of both B and T-lymphocytes. The characteristic expression pattern of the histiocytes for fascin along with co-expression of S-100 protein and a consistently weaker and variable expression of macrophage-lineage markers point more towards a dendritic cell ontogeny of these cells. Further, abundant fascin expression and presence of dendritic processes indicate a differentiated or mature dendritic cell phenotype for these cells.

Peripheral lymphadenopathy in children, comparison of fine needle aspiration cytology with open biopsy

To compare the results of Fine Needle Aspiration Cytology [FNAC] with open biopsy in cases of Peripheral Lymphadenopathy. A comparative study. Department of Paediatric Surgery and Department of Pathology, Nishtar Medical College and Hospital, Multan from January 2004 to September 2004. Patients presenting with Peripheral Lymphadenopathy in Paediatric Surgery out patient department were included in study. Relevant history and clinical findings were entered in performa and patients were submitted to investigations like FNAC and open lymphnode biopsy, after getting consent, on OPD basis. Results of both FNAC and histopathology in 54 patients were available for comparison at the end of study. FNAC showed tuberculosis in 36 [66.67%], lymphoproliferative process in 16 [29.63%] and poor yield in 2 [3.71%] cases. Whereas open lymphnode biopsy on histopathology confirmed tuberculosis in 42 [77.78%], Hodgkins lymphoma in 4.[7.42%], Non Hodgkins in 6 [11.13%] and reactive hyperplasia in 2 [3.71%] cases. Sensitivity of FNAC in tuberculosis was 85.7% with a specificity of 100% in cases of tuberculosis while it was 71.5% in cases of lymphomatous process with an overall sensitivity of 78.5% in peripheral lymphadenopathy. In our setup lymphnode biopsy should be performed in all suspected cases to avoid long term morbidity and mortality especially in clinically malignant illnesses

role of fine needle aspiration cytology and imprint cytology in cervical lymphadenopathy

To determine the diagnostic accuracy of cervical lymphadenopathy by fine needle aspiration [FNAC] and imprint cytology [IC]. This study included 94 patients with cervical lymphadenopathy. This study was carried out in the Departments of General Surgery and Pathology, King Fahad Hospital, Hofuf, Kingdom of Saudi Arabia, from June 2001 through to July 2002. They were subjected to clinical examination and FNAC of one of the enlarged lymph nodes. This was followed by IC and histological examination of this lymph node after its excision. Clinical examination was correct in 78% of the cases. The overall accuracy of fine needle aspiration was 93%. It was accurate on all cases of reactive hyperplasia, 93% of tuberculosis lymphadenitis, 90% in Hodgkin's lymphoma, 86% in non-Hodgkin's lymphoma, and 91% of metastasis lymphadenopathy. On the other hand, the overall accuracy of IC was higher than that of fine needle aspiration, being 97%. It diagnosed all cases of reactive hyperplasia and non-Hodgkin's lymphoma, 97% in tuberculosis lymphadenitis, 90% in Hodgkin's lymphoma and 95% in metastasis lymphadenopathy. These techniques proved to be reliable, rapid, and inexpensive procedures in diagnosis of lymphadenopathy. They can differentiate well between inflammatory and neoplastic lesions, in cases of lymphoma, cytological diagnosis should be followed by histological diagnosis for accurate classification and grading

Prolymphocytic leukaemia--report of three cases.

Prolymphocytic leukaemia is a rare subtype of chronic lymphocytic leukaemia. Three such cases were reported here along with clinical details. All these cases were seen in males above 5th decade. These patients showed moderate to massive splenomegaly, inconspicuous lymphadenoapthy in two cases and one with minimal lymphadenopathy. Peripheral smear showed high leukocyte count with more than 55% of prolymphocytes. Bone marrow aspiration showed diffuse involvement and in one with minimal lymphadenopathy, lymphnode aspiration showed prolymphocytes. All the three patients died within a year after diagnosis.
