Definition: Erythema induratum (EI), or nodular vasculitis, is a form of panniculitis. It is a relatively uncommon finding most classically associated with latent or active tuberculosis (TB) infection but may also be medication-induced or, rarely, idiopathic.

Tuberculides may develop as hypersensitivity to the tubercle bacillus.Lichen scrofulosorum: lichenoid eruptions of papules predominantly in children often perifollicular develop on abdomen, chest, and back (Figure 3.17).Papulonecrotic tuberculide: papules arise and develop central necrosis with a black crust.Erythema induratum: uncommon disorder, which in many cases appears to fulfil the criterion of being a response to tuberculous infection. It is characterized by the development of plaque-like areas of induration and necrosis on the lower calves and occurs predominantly in young women.

Tuberculides may develop as hypersensitivity to the tubercle bacillus. In papulonecrotic tuberculide, papules arise and develop central necrosis with a black crust. Erythema induratum is an uncommon disorder, which in many cases appears to fulfil the criterion of being a response to tuberculous infection. It is characterized by the development of plaque-like areas of induration and necrosis on the lower calves and occurs predominantly in young women.

Cutaneous manifestations in GCA are uncommon and scalp necrosis associated with GCA has mainly been reported. Tsianakas et al. reviewed 78 cases that were published between 1946 and 2007 [11]. There are only two case reports of GCA with painful lower leg erythematous lesions. Gračanin et al. reported a patient with erythema induratum of Bazin [12]. Goldberg et al. reported a patient with GCA who developed skin lesions that were clinically identical to EN; however, on biopsy they were found to be subcutaneous multinucleated giant cell vasculitis [6]. They considered these skin lesions to indicate the cutaneous involvement of GCA [6]. In two case reports, skin lesions co-existed at the time of the GCA diagnosis [6,12]. In the present case, there were no characteristics of GCA at the diagnosis of EN and subcutaneous multinucleated giant cell vasculitis was not detected.

Cutaneous tuberculosis is divided into three categories as follows: Inoculation tuberculosis, a primary infection of the skin that is introduced by an exogenous source, e.g. lupus vulgaris and tuberculous chancre.Secondary tuberculosis, either by contiguous or haematogenous spread from a primary focus that leads to involvement of the skin, e.g. scrofuloderma.Tuberculids which are hypersensitivity reactions to M. tuberculosis components, e.g. papulonecrotic tuberculid, erythema induratum of Bazin and lichen scrofulosorum.

Various clinical types of cutaneous TB, such as lupus vulgaris, scrofuloderma, tuberculosis verrucosa cutis occur. Tuberculids (lichen scrofulosorum; papulonecrotic tuberculid; erythema induratum; and erythema nodosum), TB chancre, miliary TB of the skin have also been described. Following bacille Calmette-Guerin (BCG) vaccination, localized and generalized skin complications have also been described [2].
