It can be transmitted either through hematogenous or lymphatic spread but most commonly through contiguous extension.There are many reports on different form of lupus vulgaris but there are only a few reports on large sized lupus vulgaris.

Summary
Lupus vulgaris is the most common form of cutaneous tuberculosis which is chronic and progressive in nature.[1]. We present here a case of giant arcuate shaped lupus vulgaris, rapidly progressing over a period of just two years. A 75 years old male came to dermatology out-patient with a single large atropic, hypopigmented to skin colored plaque on antero-lateral chest wall for the last two years. The lesion started as few asymptomatic erythematous papules that coalesced to form plaque in the lateral part of left chest. This plaque increased gradually leaving a healed atrophic center. The approximate size of the plaque was 30 x 30 cm[2] (Figure 1) It was arcuate in shape with clearing of the adjacent areas with few areas of atrophy. Liver function test and renal function test were all within normal limits
