PRRT2 and tuberculosis: Progression to serious complications such as corneal ulceration and perforation or superimposed bacterial infection is possible if the condition is left untreated.[2] In an area with a high prevalence of TB, PKC is usually associated with a variety of disease forms, including pulmonary TB, tuberculous lymphadenitis and spinal TB.[1–3] Hypersensitivity to tuberculin protein may also be found, even without tubercular disease.[2] Hence, patients presenting with PKC, particularly those who live in areas where TB is endemic, should be thoroughly investigated for the presence of TB infection.
