Adverse effects of desensitization injections mostly consist of local transient reactions. Rarely, persistent subcutaneous nodular lesions may also develop at the site of injection. These reactions have been attributed to the vaccines containing aluminium hydroxide. Aluminium hydroxide is used as an adjuvant in vaccines and hyposensitization solutions. We describe a patient who presented persistent, itchy subcutaneous nodules as a local reaction to allergen immunotherapy for the treatment of allergic asthma., ((c) 2009 John Wiley & Sons A/S.)

Lupus vulgaris is reinfection tuberculosis of the skin and may result from direct extension, or hematogenous or lymphatic spread from a tuberculosis focus. Lupus vulgaris following bacille Calmette-Guerin (BCG) vaccination is a rare entity. Incontinentia pigmenti is an X-linked dominant genodermatosis in which vesicular, verrucous, and pigmented lesions are associated with various developmental defects. There is evidence of altered immunologic reactivity in some patients with incontinentia pigmenti. A 12-year-old girl hospitalized for pulmonary tuberculosis presented with bizarre-shaped brown macules following Blaschko lines on the left deltoid area, compatible with incontinentia pigmenti, which had appeared following BCG vaccination at the age of 7 years. Histopathologic examination found noncaseated granulomas in the dermis. Antituberculous treatment for pulmonary and cutaneous tuberculosis was initiated along with genetic counseling. Immunologic abnormalities have been reported in conjunction with incontinentia pigmenti. Simultaneous occurrence of pulmonary and cutaneous tuberculosis in our patient might be either coincidental or indicate derangements in the cellular immune system.
