Tubercular lymphadenitis: clinical manifestations.

One hundred and thirteen children suffering from tubercular lymphadenitis proven histopathologically, were studied for clinical and laboratory features. Age distribution was equal in all age groups except during infancy when it was rare. Sex ratio indicates a male preponderance with male to female in the ratio of 1.5:1 (67:46). Family history of contact with known tuberculous patient was positive in 19 (17%) children, 44 (40%) had received BCG, and 98 (88%) were either normal nourished or had mild malnutrition. Cervical, axillary and inguinal nodes were found in 90 (80%), 14 (12%), and 8 (7%) children respectively. Epitrochlear node was found in only 1 child. 11 (10%) children had discharging sinus, all being in cervical group. The consistency of nodes was firm in 98 (87%), fluctuation was present in 15 (13%). In 87 (77%) lymph nodes were matted. Hepatomegaly of more than 2 cm was present in 13 (11%) and spleen was enlarged (> 2 cm) in 4 (4%) only: Mantoux test was positive in 96 (85%) children and chest X-ray was abnormal in 25 (22%) cases. Findings suggest that tubercular adenitis occurs in all age groups with equal frequency. It can occur in vaccinated children also. It may be a sole manifestation of tubercular infection. The cervical nodes are predominantly involved. There is no typical location of nodes in individual groups but multiplicity and matting of nodes are characteristic features of tubercular adenitis in children.
