Introduction:

Silicosis is a disease usually of occupational origin. Sarcoidosis is a multisystemic disease of unknown etiology. The radiological patterns of silicosis and sarcoidosis can be similar.

Case statement:

A 42 years old male, marbleist, diagnosed of sarcoidosis and who presents radiological hilar adenopathies and pulmonary nodules in both lobes. Suspicion of professional origin of silicosis is declared, subsequently ratified by the National Institute of Security Social.

Discussion:

The diagnosis of silicosis is based on the concurrence of the following criteria:

- Work history of exposure to crystalline silica.

- Simple chest x-ray with profusions > o = 1/1 (ILO classification).

- Exclusion of other possible entities.

Sarcoidosis is pathologically characterized by the presence of non-caseating granulomata in the organs involved.

Conclusions:

The clinical and occupational context of the disease is crucial in order to establish a correct diagnosis.
