Résumé
Background: FNAC (Fine Needle Aspiration Cytology) is a well accepted technique and plays an important role in early diagnosis of head and neck lesions. It is a safe and inexpensive outdoor procedure. Materials and methods: This study was carried out over a period of 9 months (January 2021 to September 2021). A total of 60 patients with head and neck lymphadenopathy were subjected to FNAC at a tertiary care centre in Vadodara, Gujarat. All reports were recorded and data was entered and analyzed using Microsoft excel. Results: In the present study, the various causes of head and neck lymphadenopathy were classified according to cytomorphological patterns. Among the diagnostic outcome, overall prevalence of granulomatous lymphadenitis was 35% (21 cases), reactive hyperplasia was 26.67% (16 cases), secondary metastases were 18.33% (11 cases), lymphoma was 10% (6 cases) and acute non-specific lymphadenitis was 10% (6 cases). Conclusion: FNAC is simple, quick, inexpensive and safe diagnostic procedure which also is an useful adjunct to histopathology.
Résumé
The most common cause of granulomatous lymphadenitis in countries like ours is mycobactrium tuberculosis followed by atypical mycobacterial infection, fungal infections, parasitic infection, cat scratch disease, lymphogranuloma venereum (inguinal lymphadenopathy), and leprosy Here, we present three cases of lymphadenopathy due to histoplasmosis in immunocompetent children. Two of them presented with fever, lymphadenopathy, initially diagnosed as granulomatous lymphadenitis consistent with tuberculosis on FNAC and were put on antitubercular drugs. However, their condition gradually became worse. As the patients continued to deteriorate, subsequent lymph node biopsies were done and diagnosed as histoplasmosis. Third case presented with acute loss of vision with hepatosplenomegaly and lymphadenopathy. Initially considered as acute leukemia, but eventually established as histoplasmosis. Histoplasmosis should be considered as one of the possible causes of granulomatous lymphadenitis in children.
Résumé
Introduction: Lymph nodes are an integral component of the immune system and their enlargement is commonly noted in clinical practice in a wide spectrum of diseases, including infections like tuberculosis and malignancy. FNAC is an important diagnostic tool for rapid evaluation of mainly superficial lesions, especially of lymph nodes. It is cost effective, relatively less traumatic, and enables the pathologist to provide the clinician with a diagnosis in a very short time, and hence is ideal especially for OPD patients. Objectives: 1. To study the age and sex distribution of the patients of FNAC of peripheral lymph node. 2. To study the spectrum of diseases diagnosed on FNAC of peripheral lymph nodes. Methods: Cross-sectional hospital based Observational study. Total 50 patients who had superficial lymphadenopathy were included in this study. Male patients were 21 (42%) and Female patients were 29 (58%). FNAC was performed on this 50 patients. Diagnosis was made by light Microscopy. Result was tabulated and statistical analysis was done. Results: Male patients were 21 (42%) and Female patients were 29 (58%). 50 % patients were in the age group of 21 to 40 years. Reactive hyperplasia was 46% and Granulomatous lymphadenitis was 18%. Cervical lymph nodes were most commonly involved. Conclusion: FNAC is a simple, quick, low cost, minimally invasive and easy diagnostic procedure which is very much helpful in the diagnosis of diseases causing superficial lymphadenopathy in all age groups. Reactive hyperplasia of lymph node was the most common cytological diagnosis followed by Granulomatous lymphadenitis.
Résumé
Patients infected with human immunodeficiency virus frequently manifest with rare infections as well as neoplasms. We report an unusual and interesting case of an intranodal Kaposi's sarcoma (KS) with coexistent/concurrent granulomatous lymphadenitis secondary to atypical mycobacteria in a groin lymph node. "Mycobacterium pseudotumor" is a nonneoplastic condition and should be distinguished from true KS as these 2 entities differ in their prognosis and treatment. In this article, we discuss the diagnosis and differential diagnosis of this exceptional clinical and pathologic manifestation.
