Primary carcinoid tumour of the kidney. A case report and review of the literature.

Carcinoid tumours are known to occur frequently in the gastrointestinal and respiratory tracts. A primary carcinoid tumour of the kidney is an extremely rare entity and only 40 cases have been reported in the literature. As a consequence, very little is known about its real histogenesis, and its prognosis and clinicopathological patterns are not precisely defined.

Detection of Dirofilaria (Nochtiella) repens DNA by polymerase chain reaction in embedded paraffin tissues from two human pulmonary locations.

We here report two new cases of human pulmonary dirofilariasis in men aged 62 and 64 from Northern and Central Italy, respectively. Both were asymptomatic and the infections were discovered incidentally when chest radiographs taken for another reason revealed the presence of a coin lesion. The initial clinical diagnosis was oriented towards a lung tumour, and an excisional lung biopsy after thoracotomy was necessary for the final diagnosis.
