Colocolic intussusceptions are rare clinical entities in adults and almost always caused by a leading lesion which often warrants resection. Mostly being malignant, the leading lesions are rarely benign lesions where intraluminal lipomas are the most frequent among them. Most adult intussusceptions require surgical resection owing to two major reasons: common presence of a leading lesion and significantly high risk of malignancy—reaching as high as 65% regardless of the anatomic site—of the leading lesion. Resection of the affected segment is usually the treatment of choice, since preoperative diagnosis of the lesion is usually ineffective and most leading lesions are malignant. This paper represents two cases of adult colocolic intussusception caused by intraluminal lipomas with a brief review of the literature.

Type Substitution

There are >200 different types of human papilloma virus (HPV) of which >51 infect genital epithelium, with ~14 of these classed as high-risk being more commonly associated with cervical cancer. During development of the disease, high-risk types have an increased tendency to develop a truncated non-replicative life cycle, whereas low-risk, non-cancer-associated HPV types are either asymptomatic or cause benign lesions completing their full replicative life cycle. HPVs can also be present as non-replicative so-called “latent” infections and they can also show superinfection exclusion, where cells with pre-existing infections with one type cannot be infected with a different HPV type. Thus, the HPV repertoire and replication status present in an individual can form a complex dynamic meta-community which changes with respect to both time and exposure to different HPV types. In light of these considerations, it is not clear how current prophylactic HPV vaccines will affect this system and the potential for iatrogenic outcomes is discussed in light of recent outcome data.

Solitary fibrous tumours of the pleura are rare pleural neoplasms that are distinct from mesothelioma. Most of them are benign, although some behave aggressively; morphological and pathological features are important in distinguishing them from mesothelioma and in predicting clinical behaviour. Solitary fibrous tumours often grow to a large size before causing symptoms, and are characteristically associated with hypertrophic pulmonary osteoarthropathy in up to 20% of cases. In cases of benign lesions, complete resection is usually curative. A case involving a 62-year-old woman who underwent surgical resection of a solitary fibrous tumour of the pleura measuring 25 cm in size is described.

Cystic Pancreatic Lesions

Introduction. The management of cystic pancreatic lesions has changed in recent years as a result of increasing knowledge of their biological behaviour, better diagnostic options, and international guidelines. Methods. Retrospective analysis of a cohort of 86 patients operated for cystic pancreatic lesions during a seven-year period (2007–2014). Results. Final histopathology revealed 53 intraductal papillary mucinous neoplasms (19 branch duct IPMNs, 15 mixed type IPMNs, and 19 main duct IPMNs), 14 serous and 13 mucinous cystic neoplasms, 3 solid pseudopapillary neoplasms, and 3 other lesions. 4 cases displayed high grade intraepithelial neoplasia and 2 cases displayed invasive cancer. A pylorus-preserving partial duodenopancreatectomy was carried out in 27 patients, a total pancreatectomy was carried out in 9 patients, a left resection was carried out in 42 patients, and segmental resections and enucleations were carried out in 4 patients each. Overall postoperative morbidity and mortality were 40% and 2.3%, respectively. The preoperative diagnosis of a specific cystic tumor was accurate in 79% of patients and 9 patients (10%) could have avoided surgery with the correct preoperative diagnosis. Conclusion. Cystic pancreatic lesions are still a diagnostic challenge, requiring a dedicated multidisciplinary approach. The rate of malignancy is relatively small, whereas postoperative morbidity is substantial, underscoring the importance of adequate patient selection considering both the risk of surgery and the long term risk of malignancy.
