AI Article Synopsis
- Papulonecrotic tuberculid (PNT) is a rare skin condition linked to tuberculosis, affecting individuals with strong immunity and sensitivity to mycobacteria.
- It typically manifests as recurring papulonecrotic lesions that can crust or ulcerate, leading to scars that resemble smallpox over time.
- Diagnosis involves a positive tuberculin test and specific histological findings, and PNT usually responds well to antituberculous treatment, highlighting the need for dermatologists to be aware of this condition.
Article Abstract
Papulonecrotic tuberculid (PNT) is an uncommon form of id eruption, which occurs in association with tuberculosis infections in patients with a high degree of immunity and allergic sensitivity to mycobacterial organisms. It commonly presents as recurrent crops of papulonecrotic lesions that crust or ulcerate, and heal with atrophic varioliform scars over time. The differential diagnoses of PTN are wide and varying. Tuberculin test is usually strongly positive. Histology shows tuberculoid histology with endarteritis and thrombosis of dermal blood vessels. One of the hallmarks of PNT is its prompt response to antituberculous therapy. The purpose of this article is to increase awareness of this condition among dermatologists.

Objectives: Cutaneous tuberculosis (CTB) may be over-diagnosed due to imprecise diagnostic criteria or overlooked where mycobacterial investigations are negative. We evaluated the distinction between multibacillary and paucibacillary forms of CTB, as well as drug resistance and cure rates according to the results of mycobacterial investigations.
Methods: We included retrospectively all patients diagnosed with CTB from 1995 to 2018 in two hospitals in Paris.

Article Synopsis
- Tuberculides are immune reactions to tuberculosis that occur in healthy individuals, and this study focuses on their characteristics and treatment responses in a North Indian healthcare center.
- Analyzing clinical records from 2000 to 2019, the study identified 34 patients with tuberculides, with lichen scrofulosorum being the most prevalent type, followed by other forms like erythema nodosum.
- The findings highlight that tuberculides can indicate hidden tuberculosis infections, aiding in early diagnosis and effective treatment with a standard six-month anti-tubercular therapy regimen.
