    Abstract Context.—: In the last 2 decades there has been significant progress in typing and recognition of pancreatitis, a necroinflammatory and fibroinflammatory process of multifactorial origin.
    Objective.—: To present the current state of pathology and pathogenesis of alcohol-associated pancreatitis, including paraduodenal pancreatitis. In the context of the most important epidemiologic, clinical, and radiologic features, the related macroscopic changes and histopathologic characteristics are addressed.
    Data sources.—: In acute pancreatitis we discuss the pathologic findings that distinguish mild from severe pancreatitis and highlight autodigestive fat necrosis as the initial morphologic damage. In chronic pancreatitis we present a histologic staging system that describes the damage patterns as a necrosis-fibrosis sequence that takes place during the development of early to advanced and end-stage chronic pancreatitis. In paraduodenal pancreatitis the anatomic peculiarities are related to the sequence of morphologic changes that are correlated to the most important imaging findings. Pathogenetically, we discuss the role of alcohol overconsumption in triggering autodigestive fat necrosis in the pancreas, the repair of which results in a pancreas-transforming fibroinflammatory process.
    Conclusions—: Whereas in acute pancreatitis there are no lesions that are diagnostic for alcohol overconsumption and that exclude other etiologies such as gallstone disease or drugs, the sequence of damage patterns in chronic pancreatitis are strongly related to the effect of alcohol overconsumption and allow in many cases the distinction from hereditary, autoimmune, or obstructive pancreatitis. Paraduodenal pancreatitis can be considered a special manifestation of alcoholic pancreatitis.

    Abstract Aims: Small invasive carcinomas arising in intraductal papillary mucinous neoplasms (IPMNs) of the pancreas can present as multiple, small foci. In such cases, there is no clear optimal measurement method for determining the invasive size for tumour staging and prognostication.
    Methods: In all, 117 small invasive IPMNs (size of largest invasive component ≤2 cm) from seven institutions (2000-2016) were reviewed, and all individual foci of invasive carcinoma were measured. T stages (AJCC 8th edition) based on the largest single focus size (LS), average size of all foci (AS), and total sum of all foci (TS) were examined in association with clinicopathologic parameters and patient outcomes.
    Results: The cohort comprised IPMNs with invasive tubular-type (n = 82, 70%) and colloid-type (n = 35, 30%) carcinomas. The mean LS, AS, and TS were 0.86, 0.71, and 1.32 cm, respectively. Based on the LS, AS, and TS, respectively, 48, 65, and 39 cases were classified as pT1a; 22, 18, and 11 cases as pT1b; and 47, 34, and 50 cases as pT1c. Higher pT stages based on all measurements were significantly associated with small vessel, large vessel, and perineural invasion (P < 0.05). LS-, AS-, and TS-based pT stages were not significantly associated with recurrence-free survival (RFS) or overall survival (OS) by univariate or multivariate analyses. However, among tubular-type carcinomas, higher LS-, AS-, and TS-based pT stages trended with lower RFS (based on 1-, 3-, and 5-year survival rates). All microscopic measurement methods were most predictive of RFS and OS using a 1.5-cm cutoff, with LS significantly associated with both RFS and OS by univariate and multivariate analysis.
    Conclusions: For invasive tubular-type carcinomas arising in IPMN, microscopic size-based AJCC pT stages were not significant predictors of patient outcomes. However, for LS, a size threshold of 1.5 cm was optimal for stratifying both RFS and OS. The AJCC 8th ed. may not be applicable for stratifying small invasive IPMNs with colloid-type histology that generally portend a more favourable prognosis.

    Abstract The last 50 years have witnessed an explosion in our understanding of the pathology of pancreatic diseases. Entities known to exist 50 years ago have been defined more precisely and are now better classified. New entities, previously not recognized, have been discovered and can now be treated. Importantly, new tools have been developed that have unraveled the fundamental biological drivers of a number of pancreatic diseases. Many of these same tools have also been applied clinically, supplementing the tried and true hematoxylin and eosin stained slide with a plethora of new, highly sensitive and specific tests that improve diagnostic accuracy and delineate best treatments. As exciting as these many advances are, our knowledge of pancreatic pathology remains incomplete, and there is much to be learned.

    Abstract Mucinous cystic neoplasms (MCNs) of the pancreas are primary pancreatic cyst-forming neoplasms that can be a precursor to invasive adenocarcinoma of the pancreas. MCNs occur almost exclusively in the distal pancreas of middle-aged women. MCNs typically show a "cyst-in-cyst" pattern of growth and are well encapsulated by a thick fibrous wall. MCNs are composed of mucin-producing neoplastic epithelial cells and "ovarian-type" subepithelial stroma. The epithelium is dysplastic and the grade can range from low to high grade; some MCNs have an associated invasive carcinoma. It is this associated invasive carcinoma that determines prognosis. MCNs harbor several characteristic genetic and epigenetic alterations, some of which are shared with conventional invasive pancreatic ductal adenocarcinoma. Furthermore, several studies reveal characteristic patterns of gene expression in the ovarian-type stroma that suggest steroidogenesis in the ovarian-type stroma. Better knowledge of the molecular alterations could help in the management of patients with this type of precursor of invasive carcinoma.

    Abstract Angiomyolipoma is the most common mesenchymal tumour of the kidney, even if for a long time it has been viewed as a hamartoma rather than a neoplasm. It belongs to a family of neoplasms, named PEComa, characterised by the constant presence of perivascular epithelioid cells that co-express smooth muscle and melanogenesis markers. Angiomyolipoma can occur in patients with tuberous sclerosis, a hereditary syndrome due to the alteration of TSC1 or TSC2 genes, or sporadically. Angiomyolipoma and its variants are indolent tumours; however, some epithelioid angiomyolipomas/pure epithelioid PEComas are aggressive, and criteria for malignancy have been proposed to identify those cases. Although typical angiomyolipoma is a straightforward diagnosis, pathologists should be aware of the wide morphological spectrum of its variants which could be tricky in routine clinical practice and could require immunohistochemical analysis for resolution. The differential diagnosis may range from an inflammatory process (for instance xanthogranulomatous pyelonephritis) to the most common renal cancers and sarcomas. The immunoexpression of melanogenesis markers (HMB45 and Melan-A) and cathepsin K is extremely helpful in the majority of cases. Recently, a subset of epithelioid angiomyolipoma/pure epithelioid PEComa harbouring TFE3 gene fusions has been described, raising questions about its relationship with the family of perivascular epithelioid cell tumour. The activation of the mTOR pathway due to genetic alterations of tuberous sclerosis complex in TSC1 or TSC2 genes in angiomyolipoma has also been reported as well as the subsequent therapeutic implications.

    Abstract Neuroendocrine neoplasms of the small intestine are some of the most frequently occurring along the gastrointestinal tract, even though their incidence is extremely variable according to specific sites. Jejunal-ileal neuroendocrine neoplasms account for about 27% of gastrointestinal NETs making them the second most frequent NET type. The aim of this review is to classify all tumors following the WHO 2019 classification and to describe their pathologic differences and peculiarities.

    Abstract Background: Current treatment of potentially resectable pancreatic ductal adenocarcinoma (PDAC) includes pancreatic resection followed by adjuvant therapy. Aim of this study is to identify factors that are related with overall and early recurrence after pancreatectomy for PDAC.
    Methods: Retrospective analysis of patients with histologically confirmed PDAC who underwent pancreatectomy between September 2009 and December 2014. Early relapse was defined as recurrence within 12 months after surgery. Univariate/multivariate analysis was performed to identify prognostic factors for recurrence.
    Results: 261 patients were included (54% males, mean age 67 years). Neoadjuvant and adjuvant treatments were performed in 55 (21%) and 243 (93%) patients. Overall morbidity was 56% with a rate of grade 3-4 Clavien-Dindo complications of 25%. Median disease-free survival was 18 months. Multivariate analysis identified nodal metastases (OR: 3.6) and perineural invasion (OR: 2.14) as independent predictors of disease recurrence in the entire cohort. 76 patients (29%) had an early recurrence. Poorly differentiated tumors (OR: 3.019) and grade 3-4 Clavien-Dindo complications (OR: 3.05) were independent risk factors for early recurrence.
    Conclusion: Although overall recurrence is associated with tumor-related factors, severe postoperative complications represent an independent predictor of early recurrence. Patients at increased risk of severe postoperative complications may benefit from neoadjuvant therapy.
