Clinico-Pathological Correlates of Cervical Lymphadenopathy: A Hospital Based Study

Neck is the most common site of peripheral lymph node enlargement and is very frequently encountered in oto-laryngological practice. This study was done to delineate distribution of clinico-demographic parameters in patients presenting with cervical lymphadenopathy in the otolaryngology out-patient department of a state hospital in India in a 1 year period and to correlate them with fine needle aspiration cytological diagnosis. Record-based cross sectional study in the department of Otolaryngology and department of Pathology, Calcutta National Medical College and Hospital, Kolkata. Case reports and cytological reports of 423 patients who underwent Fine Needle Aspiration Cytology (FNAC) of cervical lymph nodes between January 2009 and December 2009 were reviewed in relation to their demographic and clinical profiles. The cases were divided into three groups according to age and different parameters were described according to these groups. In the cyto-pathological diagnosis, tubercular lymph-adenitis was most prevalent diagnosis (45.4%). Among the metastatic secondaries, squamous cell carcinoma was most common (8.5%). Non-specific/reactive lymphadenitis was significantly more common in <14 years, TB lymph node in 15-59 years and malignancy among the >= 60 years age group. Jugulo-omohyoid (level III) and Supraclavicular (level VB) groups of Lymph nodes were found significantly more involved by malignancy whereas Jugulo-diagastric (level II), Post-auricular, Submandibular groups (level IB) were more commonly involved in TB. Malignancy patients presented late in respect to the tuberculosis patients. Knowledge about clinico-demographic perspectives of cervical lymphadenopathy in respect to their cytopathological diagnosis will help care giver practioners to detect/refer the respective cases early for investigations and treatment.
