Abstract

Highlights: Tuberculosis and sarcoidosis are closely related in terms of pathogenesis and clinical manifestation, and may even coexist in the same patient. When tuberculosis is recurrent or do not answer treatment without microbiological resistance, physicians have to advocate the possible association to sarcoidosis, especially in country with high tuberculosis burden. Anergic tuberculine skin test in tuberculous patients can reveale underlining sarcoidosis. Abstract: The distinction between tuberculosis and sarcoidosis presents sometimes a clinical challenge. Their sequential occurrence in the same patient is uncommon. We present the case of a 42-year-old female with a proven diagnosis of tuberculous lymphadenitis who has developed successively nasal tuberculosis and pulmonary sarcoidosis respectively after 10 and 14 months of antituberculosis treatment. The patient presented with bilateral cervical lymphadenopathy. Tuberculin skin test was negative. Chest radiography was normal. An excision biopsy was taken and histopathological examination established tuberculosis diagnosis. Therapy with antituberculosis drugs was started, and cervical lymphadenopathy showed progressive resolution. Subsequently, nearly 10 months after, the patient developed new cervical lymphadenopathies and nasal obstruction. Tuberculosis of the nasal mucosa was confirmed by biopsy. Antituberclosis bitherapy was enhanced by ofloxacin and ethambutol. Thoracic CT scan showed several nodular elements in both lungs, with bilateral enlarged mediastinal adenopathy. Bronchoalveolar lavage showed a lymphocytic alveolitis with a CD4/CD8 ratio of 5, consistent with the diagnosis of pulmonary sarcoidosis. Corticosteroid treatment, in form of oral prednisolone was introduced, 3 months after sarcoidosis diagnosis have been setteled; because of pulmonary fibrosis noticed on thoracic CT. Systemic corticotherapy was continued for a further period of 3 years, until all the lesions cleared out. The present case emphasizes the possible association between tuberculosis and sarcoidosis.
