Surgical rarities: case report of appendicular diverticulitis and literature review.

Appendicular diverticulosis is a rare condition observed in about 0.004-2% of all appendectomy specimens. Risk of perforation/bleeding is high and a relevant association with mucinous neoplasms is known.

Case report of mesenteric solitary fibrous tumour and review of the literature: 'once in a blue moon'.

Solitary fibrous tumour (SFT) is a rare mesenchymal tumour, usually originating from the serous surfaces, typically of the pleura and pericardium. However, it can also have localizations in soft tissues and visceral organs. We report the case of a 79-year-old woman affected by mesenteric SFT, localized in the sigmoid colon.
