INTRODUCTION: Cutaneous tuberculosis, although a disease of the past, is occasionally seen especially in the developing world. It can present in at least seven morphological types.1 Lupus vulgaris is the commonest morphological presentation of cutaneous tuberculosis and accounts for nearly 59% cases.2 Other types are Tuberculosis cutis, Tuberculosis verrucosa cutis, Scrofuloderma, Papular Tuberculid and Lichen scrofluolosorum. Nasal tuberculosis (TB) comes mainly from the haematogenic or lymphatic extension of pulmonary TB. They are secondary to inoculation by scratching.3 This is a chronic, progressive and tissue destructive form of cutaneous tuberculosis seen in patients with moderate or high degree of immunity.4 The lesions progress by peripheral extension central healing, atrophy and scarring. Head and neck is the commonest site of lupus lesions in European countries whereas in India, the sites of predilection are the buttocks and trunks.5, 6 Approach to these type of lesion is high clinical suspicion and histopathology which reveal tubercules of epitheloid cells, Langhans gaint cells and lymphocytes in the dermis which are the distinct features. Here we present two cases involving father and son with lupus vulgaris of external nose, interestingly occurring at the same time.
