Cutaneous tuberculosis and squamous-cell carcinoma.

The incidence of all forms of cutaneous tuberculosis, including lupus vulgaris (the most common form) decreased progressively in developed countries during the twentieth century, this change being attributed to improved living standards and specific therapy. Despite the decrease in cutaneous tuberculosis, some cases are still found and correct diagnosis and management are fundamental, both for the patients and for public health. Long lasting, misdiagnosed or untreated cutaneous tuberculosis may lead to different forms of cancer.
