Co-existing tuberculosis and malignant mesothelioma with multiple sites venous thrombosis: a case report.

BACKGROUND

Tuberculosis is endemic in India and almost 40 % of the Indian population is infected with tubercle bacilli. Tuberculosis being a great mimicker of infectious as well as non infectious diseases and recent rise of multi drug resistant and extended drug resistant cases have made diagnosis and management more difficult. To the best of our knowledge there have been no reported cases of tuberculosis coexisting with malignant peritoneal mesothelioma leading to multiple site venous thrombosis.

CASE PRESENTATION

Forty five year old male, belonging to Indian/Aryan ethnicity presented with cough, breathlessness and fever for 7 months with past history of pulmonary tuberculosis. On examination he was found to have pleural effusion for which he received anti-tuberculosis therapy empirically. Later his condition deteriorated and on further examination he was found to have ascites, multiple site venous thrombosis and pyothorax which was found positive for acid fast bacilli. Despite anti-tuberculosis therapy he did not improve and was suspected to be a multidrug resistant case. Later on computed tomography peritoneal nodule was detected and on biopsy revealed malignant mesothelioma.

CONCLUSION

In a diagnosed case of tuberculosis with clinical findings compatible with it but not responding to anti tubercular therapy, underlying secondary co-existing pathology should be explored.
