ABSTRACT
Erythema nodosum, a common type of Panniculitis, may develop due to variety of primary infectious or else antigenic stimuli. Nodular vasculitis is a related but definitely different in clinicopathologic reaction pattern of the subcutaneous fat. Current report explains history of a 22–year old Pakistani female patient who developed nodular vasculitis, induced by Chlamydophila pneumoniae. She developed cutaneous vasculitis with onset of respiratory symptoms. The patient is diagnosed with pneumonia, interstitial shadow and thorough shadow on chest CT. Diagnosis was based on clinical signs and changes in antibody titers indicating involvement of C. pneumoniae. Treatment with cephems was unproductive, whereas the newer quinolones were found effective. Following antibiotic administration, nodular vasculitis was subsided along with improvement of the pneumonia. Since this infection is very common, although this term use often asymptomatic, but it must be considered as systematically for the causative agent of nodular vasculitis. To the best of our knowledge, this is the first reported case on nodular vasculitis in Pakistan.
