BACKGROUND In Taiwan, cutaneous lesions with granulomatous lobular panniculitis, with or without vasculitis, are usually diagnosed as erythema induratum (EI), a common form of tuberculid associated with tuberculosis. However, there has been no study to elucidate the extent of this association in Taiwan. The aim of this study was to document the spectrum of the pathologic findings in EI and its ...

CONTEXT Erythema induratum of Bazin (EIB) is considered to be a tuberculid reaction and consists of recurrent painful nodules. The differential diagnosis includes diseases like nodular vasculitis, perniosis, polyarteritis nodosa and erythema nodosum. CASE REPORT We report the case of a woman with EIB who developed Addison's disease during treatment with anti-tuberculosis drugs with good respo...

India has the highest burden of tuberculosis (TB) in the world and cutaneous TB accounts for about 1.5% of extrapulmonary disease [1,2]. It is seen in greater frequency with HIV infection, which is also rampant there [1,3]. Skin lesions could be either “true” cutaneous TB (lupus vulgaris, TB verrucosa cutis, scrofuloderma, orificial TB, military TB) or tuberculids [4]. The latter are believed t...

Erythema induratum of Bazin (EIB) is a chronic nodular eruption occurring on the lower legs of young and middleaged women which is considered the most common tuberculid. A 54-year-old woman, in treatment with chemotherapy for breast cancer, presented subcutaneous erythematous plaques and nodules on the lower limbs. She had been diagnosed with EIB 3 years earlier and diagnostic work-up showed at...

Nodular vasculitis was introduced by Montgomery for cases of erythema induratum-like lesions that were not associated with tuberculosis. Nodular vasculitis has been associated with both nontuberculous infections and noninfectious conditions. However, there has been no report on the development of nodular vasculitis during tumor necrosis factor-α inhibitor treatment. A 28-year-old man visited ou...

We report a case of tuberculous granulomatous panniculitis without vasculitis in an 87-year-old female patient with B-cell chronic lymphocytic leukaemia. One month after starting chemotherapy with chlorambucil and prednisone she presented superficial erythematous plaques on the anterior side of the left leg. Three weeks later erythematous painless deep nodules appeared on the left popliteal fos...
