Masson's Lesion: A Very Rare Cardiac Mass

Francisco Albuquerque et al. Can J Cardiol. 2022 Jan.

Abstract

Masson lesion is a rare type of vascular tumour usually found in the skin and soft tissues. Histologic examination remains the gold standard for diagnosis. Treatment involves complete surgical excision, and correct diagnosis is essential to avoid unnecessary aggressive therapy. A unique case of Masson lesion presenting as an asymptomatic pericardial mass is reported for the first time. Multimodality imaging was used for a comprehensive noninvasive mass characterization. Relevant imagiologic and pathologic findings for differential diagnosis are discussed. The importance of close coordination among different medical specialties for optimal care of this unusual clinical condition is highlighted.
