AI Article Synopsis
- An 81-year-old woman with a history of kidney cancer presented with painful nodules on her lower extremities after having pulmonary nodules for years.
- A biopsy indicated she had nodular vasculitis, and further tests suggested erythema induratum of Bazin, likely linked to tuberculosis.
- Treatment with a standard antituberculous regimen led to significant improvement, highlighting how skin symptoms can indicate larger health issues.
Article Abstract
An 81-year-old woman with a history of renal cell carcinoma and years of slowly, progressively enlarging pulmonary nodules of uncertain etiology presented with several weeks of painful lower extremity nodules. A biopsy revealed changes consistent with nodular vasculitis. A purified protein derivative and QuantiFERON test were positive, favoring the diagnosis of erythema induratum of Bazin. Treatment with a standard four-drug antituberculous regimen resulted in radiographic and clinical improvement. This case emphasizes the importance of dermatologic manifestations in the detection of systemic disease.

Introduction: Nodular vasculitis (NV) is a rare form of panniculitis primarily affecting middle-aged females, presenting as painful, sometimes ulcerated nodules on the dorsal lower legs. Erythema induratum of Bazin (EIB) is a form of NV and is considered a manifestation of cutaneous tuberculin hypersensitivity. This retrospective study aims to analyze demographics, clinicopathological findings, laboratory results, and treatment outcomes of NV in a non-TB endemic country.

We describe a case of erythema induratum of Bazin (EIB) that presented recurrently on the extremities during treatment with anti-tuberculosis medications. The anti-tuberculosis medications were effective, so they were continued despite the occurrence of the EIB lesions, and those lesions disappeared 5 months after first appearing. EIB is currently considered a multifactorial disorder with many different causes, with tuberculosis being an example, and it is thought to be a hypersensitive immune response to .

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.
