Giant Bullous Reaction in Response to Tuberculin Test in a Patient of Pelvic Inflammatory Disease

Tuberculin test is an example of delayed hypersensitivity type reaction. Most of the patients develop mild reaction in form of erythema and induration by 24 hours, which reaches epitome at 48 to 72 hours. Hereby the case of a middle aged female who presented with vaginal brownish discharge along with lower abdominal pain and primary infertility has been reported . Transvaginal ultrasonography showed right adnexal mass suggestive of hydrosalpinx. Intradermal tuberculin test was performed which atypically lead to formation of giant bulla of size 30×32 mm by 12 hours. We report this exaggerated response to a standard 5TU tuberculin test, which was later diagnosed as tubercular lymphadenitis with tubercular pelvic inflammatory disease that may be the reason for primary infertility.
