Multifocal tuberculosis verrucosa cutis

Area of Science:

• Dermatology
• Infectious Diseases
• Microbiology

Background:

• Tuberculosis Verrucosa Cutis (TBVC) is a rare, verrucous form of cutaneous tuberculosis.
• It results from direct skin inoculation in immunocompetent individuals with moderate to high immunity.
• The incidence of cutaneous tuberculosis has significantly declined in Western countries and India.

Observation:

• Recent studies indicate a resurgence in the Indian subcontinent, with prevalence rates of 0.7% and 0.26%.
• This case presents an immunocompetent individual with an indolent and extensive manifestation of TBVC.
• The clinical presentation underscores the potential for significant skin involvement.

Findings:

• Histopathology is crucial for diagnosing TBVC.
• Empirical antitubercular therapy can serve as an adjunct diagnostic tool.
• The indolent nature of the disease can lead to extensive skin lesions.

Implications:

• This case emphasizes the importance of considering TBVC in differential diagnoses, even in immunocompetent individuals.
• Accurate diagnosis through histopathology and therapeutic trials is vital for effective management.
• Understanding the epidemiology and clinical presentation aids in recognizing this rare form of tuberculosis.
