Multiple myeloma is a little-known disease in young adults, it is rarely reported before the age of 30, even less if it is light chains. We report a case illustrating one of these exceptional situations. It has characteristics as organic sounding extended and favorable response to treatment despite diagnostic delay. We wanted to take the opportunity to raise awareness about the possibility of myeloma in adults at any age.
Introduction: intracardiac thrombosis is a rare complication of antiphospholipid syndrome (SAPL), which can occur as an intracardiac tumor. His discovery usually precedes the diagnosis of SAPL.
Observation: We report the case of a young Moroccan patient who underwent surgery after the discovery of a right intra-auricular tumor. It was an organized thrombus and in the aftermath we diagnosed an SAPL. The progression was favorable under anticoagulant in addition to corticosteroid therapy.
Conclusion: The discovery of an intracardiac tumor in a young subject must evoke the diagnosis of cardiac thrombus and carry out an etiological investigation in search of an SAPL in particular.
