We report a new case of splenoma in a previously healthy adult. A 52-year-old man was admitted for a splenomegaly with thrombocytopenia. The computed tomographic scan showed a tumor which measured 56 mm in diameter. A splenectomy was performed. Histologic examination of the splenectomy specimen revealed a splenoma. Splenoma or splenic hamartoma is a rare primary splenic tumor most often incidentally discovered, radiologically. It can also meet in a particular pathological context, evoking more a coexistence rather than an association or a complication, underlying the role of the pathologist in its diagnosis.
