ABSTRACT

The synchronous occurrence of three different types of renal tumor in a patient is rare. We report a case of conventional (clear cell) renal cell carcinoma harboring metastatic foci of mammary carcinoma associated with two angiomyolipomas in the left kidney incidentally discovered at the autopsy. The patient was a 75-year-old woman, without the tuberous sclerosis complex, who had undergone left radical mastectomy and radiotherapy for an infiltrating duct carcinoma of breast 30 years before. This tumor was widely disseminated at autopsy, but the nontumorous renal parenchyma was free of metastases. To the best of our knowledge this combination of neoplasms has not been described before. This case shows the important role played by autopsy in the accurate investigation of interrelations among coexisting tumors.

ABSTRACT

A primary tracheal lymphoma with immunoglobulin G (IgG)-associated monoclonal serum paraprotein treated with surgery and chemotherapy is reported. As far as we know this is the first lymphoplasmacytoid lymphoma reported in the tracheobronchial tree and the first with a serum and tissue IgG monoclonal paraprotein. Differential diagnosis must be made essentially with extramedullary plasmacytoma and mucosa-associated lymphoid tissue lymphoma. CD-45RB strong positivity and the absence of lymphoepithelial lesions may help to differentiate lymphoplasmacytoid lymphoma from them. We expand the spectrum of lymphoid lesions with plasmacytoid features that can occur in the tracheobronchial tract.
