Methods A 6-year-period retrospective analysis of 729 consecutive PET-CT scans of H&N cancer patients was performed in order to record the incidence of below-diaphragm metastases and below-diaphragm synchronous primary malignancies. The four main indications of PET-CT in H&N cancers are; pre-treatment staging of high-risk of disseminated disease, metastatic cervical lymphadenopathy with unknown...

Synchronous presentation of primary nodal plasmacytoma and prostate cancer is very rare and has not been described in the literature. Here, we report a case of a patient with nodal plasmacytoma whose clinical presentation was suggestive of metastatic prostate cancer in the setting of recently diagnosed prostate cancer. The workup and treatment of both malignancies as well as a possible underlyi...

Renal cell carcinoma constitutes about 3% of adult malignancies. It has a high metastatic potential associated with synchronous or metachronous metastatic disease. Further, it is known to metastasize mainly to the lung, bone, brain, liver, or adrenal glands. In very rare cases it can metastasize to the gallbladder mimicking acute cholecystitis on clinical exam. In this case we present a patient...

The changing face of the AIDS epidemic since the introduction of protease inhibitors has had a significant impact on AIDS-related malignancies. These issues, emerging concepts regarding pathophysiology and current treatment strategies, are the subject of this review.

Hodgkin lymphoma (HL) is a lymphoproliferative disease arising in the lymphoid tissue, which is characterized by Reed–Sternberg cells. Adenocarcinoma is the most frequent pathological type of stomach cancer. Improved survival in HL patients leads to the development of secondary malignancies. However, synchronous occurrence of these 2 malignancies is extremely rare. Here, we present a 45-year-ol...
