Abstract:
A case with chronic necrotizing pulmonary aspergillosis that was mimicking the radiomorphology of malignant tumor was reported. The patient was admitted to hospital with progression of a left upper lobe infiltrate which was known and under regular observation for 8 years, and haemoptoe. Computer tomography scan showed a spiculated abnormality in the left upper lobe with mediastinal lymphadenomegaly. Based on this finding pulmonary malignancy was suspected and, therefore, the patient was referred to surgical intervention. The post surgical histology revealed aspergillus in the specimen. Since signs of vascular invasion could not be detected microscopically and the disease developed in immunocompromised patient (due to diabetes mellitus and long term steroid treatment) the clinical condition was determined as chronic necrotizing aspergillosis. It is very likely that the pathogen infected the patient during his daily work in a bakery. The present paper also summarizes the clinical aspects, differential diagnosis and therapy of different forms of pulmonary aspergillosis with emphasis on chronic necrotizing pulmonary aspergillosis.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
