Unusual presentation of Streptococcus pneumoniae in human immunodeficiency virus infection.

Streptococcus pneumoniae usually produces infection of the respiratory tract, inner ear or meninges. Unusual sites of infection have rarely been reported among HIV-1 seropositive patients. We report a case of post auricular subcutaneous abscess caused by Streptococcus pneumoniae in a Human Immunodeficiency Virus (HIV) infected child who also had B cell lymphoma. This case is uncommon as there was no other documented primary focus of pneumococcal infection or a preceding history of bacteraemia or respiratory infection.
