[Cutaneous sarcoidosis secondary to inhalation of wall insulating material particles]

Sarcoidosis is a systemic disease defined by multiple granulomas. We report a case of sarcoidosis which occur concomitantly or secondary to foreign body granuloma of the lung.

A 50-year-old women presented with Lofgren syndrome, subcutaneous granulomatous nodular lesions on the arms and legs. Computed tomography revealed a foreign body granuloma of the lung centered on particles of mural isolation material that the patient had inhaled accidentally. Analysis of the foreign body particles showed non crystalline silica, calcite monohydrate and phenol resin.

Recent studies support the hypothesis that sarcoidosis is an antigen-driven disease involving pulmonary T-cell activation. The antigen-mediated reaction may be caused by infectious agents, particularly mycobacteria, occupational and environmental agents (beryllium) or as in our observation following inhalation of mural isolation material particles.
