Background: Since its outbreak in early 2020, the COVID-19 pandemic has diverted resources from non-urgent and elective procedures, leading to diagnosis and treatment delays, with an increased number of neoplasms at advanced stages worldwide. The aims of this study were to quantify the reduction in surgical activity for indeterminate thyroid nodules during the COVID-19 pandemic; and to evaluate whether delays in surgery led to an increased occurrence of aggressive tumours.
Methods: In this retrospective, international, cross-sectional study, centres were invited to participate in June 22, 2022; each centre joining the study was asked to provide data from medical records on all surgical thyroidectomies consecutively performed from Jan 1, 2019, to Dec 31, 2021.
Polypoid melanoma is considered an exophytic and frequently non-pigmented variant of nodular melanoma with an adverse prognosis; however, very few studies have been published about it with contradictory results. Therefore, our objective was to determine the prognostic value of this configuration in melanomas. A transversal retrospective study of 724 cases was analyzed according to the main configuration (polypoid vs.

- Solid and papillary neoplasm of the pancreas (SPNP) is a rare tumor primarily affecting young women, characterized by its large size and favorable prognosis.
- A case study is presented involving a 34-year-old woman who was misdiagnosed with ductal carcinoma but, upon surgery for a 15 cm pancreatic tumor, was confirmed to have SPNP.
- The study emphasizes that even in older women, SPNP should be considered when a large abdominal mass is found, as surgical resection is the best treatment due to the tumor's low malignancy potential and excellent prognosis.
