[Soft-tissue mass as a rare presentation of sarcoidosis]. / Een wekedelenzwelling als zeldzame manifestatie van sarcoïdose.

ABSTRACT

BACKGROUND: The most important differential diagnosis of a soft-tissue mass is soft-tissue sarcoma, and the diagnostic process should be aimed at diagnosing or excluding this. CASE DESCRIPTION A 28-year-old man was referred to the surgeon with a progressive painless swelling on the right shoulder. Diagnostic imaging suggested a sarcoma with axillary lymphadenopathy. Repeatedly biopsy revealed a non-necrotizing granulomatous inflammation. A diagnosis of sarcoidosis was finally made, after exclusion of malignancy and infectious causes. CONCLUSION: When a patient presents with a soft-tissue mass, malignant causes such as soft-tissue sarcoma should be excluded. If pathological investigation reveals a granulomatous inflammation, a soft-tissue mass as a rare presentation of sarcoidosis should be considered. It is, however, important to first exclude a sarcoid-like reaction.
