A 45 yrs old man presents with progressive cervical lymph nodes enlargement, since 3 months; most diagnostic investigation is:
X-ray soft tissue
FNAC
Lymph node biopsy
None of the above
In cervical lymph node enlargement, if no mucosal lesion is detected, an excision biopsy of the largest node should be performed. Ref: Harrison's Internal Medicine, 15th Edition, Page 362 and 18th Edition, Page 467.
