Exaggerated Mantoux reaction in a case of latent tuberculosis infection (LTBI).
A 42-year-old female presented with a history of receiving PPD on right forearm intradermally before two days. Patient started having itching and irritation within a few hours and pain, oedema and vesicles formation by next day at the injection site. On examination, the whole right forearm was oedematous with induration of size 50 mm x 50 mm around the site of injection. Tubercular infection was suspected and the patient was subjected to further investigation but nothing, including physical examination, hemogram, fundus examination, chest X-ray, USG abdomen and CT thorax, was found suggestive of tuberculosis, leading to a diagnosis of LTBI.
