Castleman’s Disease Presenting as a Tumorous Paracardiac Formation

Castleman’s disease (in the literature also known as angiofollicular hyperplasia) is a rare benign lymphoproliferative disease. Clinically, it can manifest as unicentric or multicentric disease. Unicentric disease is most often diagnosed by accident or by symptomatology resulting from compression upon the adjoining anatomical structures. Considering its lymphatic origin, tumor mass can theoretically occur in any body region. We present a case of paracardiac localization of unicentric Castleman’s disease in a previously healthy 24-year-old woman. In such clinical cases, the specific localization of the tumor and its radiological properties can pose a differential diagnostic dilemma. Correct diagnosis is only possible after complete surgical excision and histopathologic analysis, which is the optimal therapeutic approach in this disease
