Summary
Papulonecrotic tuberculid (PNT) is a skin condition diagnosed through clinical signs, positive tuberculin tests, and biopsy. Long-term treatment is recommended due to potential recurrences even with multiple-drug therapy.
Area of Science:
- Dermatology
- Infectious Diseases
- Pathology
Background:
- Papulonecrotic tuberculid (PNT) is a rare cutaneous manifestation of tuberculosis.
- Diagnosis relies on characteristic clinical presentation, positive tuberculin tests, and histopathology.
Purpose of the Study:
- To report on cases of PNT observed at the Institute of Dermatology, Bangkok.
- To evaluate diagnostic criteria and treatment outcomes for PNT.
Main Methods:
- Retrospective review of eleven PNT cases diagnosed between 1985-1986.
- Clinical, histopathological, and therapeutic data were analyzed.
Main Results:
- Cases presented with symmetric, scattered, papulopustular necrotic lesions with atrophic scarring.
- All patients showed strongly positive tuberculin tests and improved with antituberculous therapy.
- Three cases experienced recurrences after treatment cessation.
Conclusions:
- Antituberculous therapy is effective for PNT.
- Long-term treatment is advised due to the risk of relapse.
