Non-healing ulcers as an atypical presentation of Lupus Vulgaris in an adult Filipino: A case report

ABSTRACT

@#Cutaneous tuberculosis (TB) occurs rarely, comprising only approximately 1% of all extrapulmonary TB cases worldwide. This report presents an atypical clinical manifestation of Lupus vulgaris, the most common form of cutaneous TB. Typically, Lupus vulgaris presents as chronic erythematous plaques over the head and neck area. The patient, a 24-year-old male with limited support and financial resources, presented with chronic painful, non-healing ulcerated lesions on his left upper extremity. Diagnostic tests specific to TB infection, including culture, all turned out negative for TB. No improvement in the lesions was noted with antibacterial and antifungal therapies. Clinical course of the condition and histopathologic findings, though non-specific to TB, became the basis for diagnosis and treatment. Patient currently is on the 3rd month of anti-Koch’s treatment with noted gradual improvement in the character and appearance of the lesions. Lupus vulgaris could appear as ulcers and over the extremities though much less common, posing challenges in both diagnosis and treatment. Malignant transformation could develop if left untreated. Thus, careful and thorough examination of the patient and diligent follow-up and re-evaluation of lesions while considering the patient’s values, concerns and financial capacity, were necessary in successfully addressing both the biomedical and psychosocial aspect of the illness.
