Cystic “feminine” pancreatic neoplasms in men. Do any clinical alterations correlate with these uncommon entities?

IntroductionMucinous cystic neoplasm (MCN) and solid pseudopapillary neoplasm (SPN) of the pancreas are uncommon hormone-related pancreatic tumors (HRPTs) with a clear predominance in young women. This trial aims to investigate the possible association between HRPTs development in males and phenotypic and sex hormone alterations.MethodsWe performed a retrospective analysis of our database between February 1990 and February 2012. Risk factors for sexual dysfunction were considered exclusion criteria. We investigated secondary sexual characteristics development, sex hormone level and overall sexual dysfunction degree according with the International Index of Erectile Function Questionnaire (IIEF).ResultsWe initially identified 25 patients [(MCN: n = 16 (64%); SPN: n = 9 (36%)]. At follow-up, 5 patients were lost, 8 resulted dead and 3 were excluded according to exclusion criteria. We finally enrolled 9 patients (MCN: n = 5; SPN: n = 4). Puberty occurred within physiological age for 7 patients, whereas it was delayed in 2 cases. Three patients revealed mild to moderate sexual dysfunction, along with low testosterone level in two cases. One patient presented hormonal alteration with a normal IIEF score.DiscussionIn this study, the first in literature with similar aim, hormonal and/or sexual dysfunction was present in 4 out of 9 patients affected by HRPT. The rarity of these lesions makes further trials to be needed for reliable conclusions.
