Multiple primary cancers may occur in the same patient, with a prevalence that follows an ascendant trend. Their development is dictated by a complex interplay between a variety of factors, both patient-dependent and external. The case of a 38-year-old female patient diagnosed and treated for pancreatic cancer (PC) is presented in whom the digital dermoscopic monitoring of melanocytic nevi revealed a marked change of two nevi that acquired rapidly highly atypical features. They were surgically excised and the histopathological examination revealed two completely excised dysplastic compound nevi. Clinicians should be aware of the strong association between dysplastic nevus syndrome and PC, a malignancy associated with an extremely poor prognosis. Familial atypical multiple mole melanoma syndrome (FAMMM) predisposes to the development of melanoma, pancreatic cancer and other neoplasms. The common genetic background of PC and hereditary melanoma is discussed and the importance of regular skin checkup and screening for PC in these patients is underlined. [ABSTRACT FROM AUTHOR]

Seasonal allergic rhinitis (SAR) is one of the most frequent chronic conditions of the modern world. Pollen carried by the wind from pollinated trees is a major source of SAR. Betulaceae, Oleaceae and Platanus are the most important sources of airway sensitization with regard to tree pollen and, therefore, they are included in the official recommendations of skin prick testing by different official societies. Salicaceae pollen is a moderate source of pollen sensitization. Conversely, large areas are covered with poplars and willows around the world. A number of studies from many countries showed that in some particular situations (large and compacted areas covered by Salicaceae, weather conditions, air pollution, urban ornamental vegetation), poplar and willow pollens may become of local importance in producing SAR. The aim of this review was to present a synthesis of information regarding Salicaceae pollen allergy showing that, if various unfavorable aspects are brought together, a minor problem (Salicaceae sensitization) can became a public health problem.
