RESUMO
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. This case report involves a 74-year old male farmer with lupus vulgaris on his face. During anti-tuberculosis treatment he developed a tumor on his forehead, which was histologically confirmed as a squamous cell carcinoma.
A incidência de todas as formas de tuberculose cutânea, incluindo o lúpus vulgar (a forma mais comum) diminuiu progressivamente nos países desenvolvidos durante o século XX e esta mudança foi atribuída a melhores condições de vida e uso de terapia específica. Apesar da diminuição da TBC cutânea, alguns casos ainda são detectados hoje em dia e o diagnóstico acurado e o tratamento apropriado são fundamentais para os doentes e a saúde pública. A TBC cutânea quando prolongada, diagnosticada erroneamente ou não tratada pode levar a diferentes neoplasias. Este é o relato de um caso de lúpus vulgar na pele do rosto de uma paciente do sexo masculino, agricultor, de 74 anos de idade. Durante a terapia antituberculosa ele desenvolveu um tumor na pele da testa, histologicamente confirmado como carcinoma de células escamosas.

Cutaneous tuberculosis may be associated with concurrent systemic foci in the body such as lung, lymph node, bone or CNS. Phlyctenular keratoconjunctivitis (PKC) is a manifestation of immunological response to a variety of antigens in the eye, tubercular focus (evident or occult) being the commonest in India. Reports in the existing literature have shown lungs and lymph nodes to be the predominant underlying focus associated with PKC, whereas cutaneous tuberculosis has seldom been found in this situation. We report this forgotten association in two children with cutaneous tuberculosis, one each with lupus vulgaris and scrofuloderma, who also had PKC. Interestingly, one of the cases also had simultaneous lichen scrofulosorum, which is also an immunological response to tubercular antigen and manifests in the skin, thus showing immunological manifestation in two different organ systems along with cutaneous focus of tuberculosis.
