Introduction
The diagnosis of sarcoidosis is challenging, especially if the patient has concomitant infectious symptoms. Furthermore, the overlap of immune-mediated and infectious pathologies is not uncommon.
Objective
To report a rare case of association between tuberculosis and sarcoidosis.
Materials and methods
Description of the clinical characteristics of a patient who presented with sarcoidosis superimposed on tuberculosis.
Results
The case of a 29-year-old man with ocular, cutaneous, and systemic symptoms is described. Uveitis and chronic non-caseating granulomatous findings were diagnosed in the skin, lungs, and lymph nodes. Suspicion of tuberculosis led to positive molecular biology tests only in the lymph node biopsy. An overlap of sarcoidosis and tuberculosis was determined, and combined treatment with glucocorticoids and anti-tuberculosis agents was initiated, resulting in improvement of the patient.
Conclusions
Sarcoidosis and tuberculosis share characteristics from their aetiology to clinical manifestations, posing a challenge in clinical differentiation. Cases have been documented where both diseases overlap in the same patient.
