Association of Cutaneous Immune-related Adverse Events with Overall Survival and Progression-free Survival in Oncology Patients Receiving Immune Checkpoint Inhibitors: A Prospective Study of 189 Patients in a Spanish Tertiary Care Hospital.

Cutaneous immune-related adverse events (cirAEs) may be associated with tumoral response and survival in patients using immune checkpoint inhibitors, but this relationship remains unclear because previous reports on the topic have various limitations. The purpose of this study was to examine the association of cirAEs with overall survival and progression-free survival in patients starting immune checkpoint inhibitors. A prospective observational study was conducted in a Spanish tertiary care hospital, including participants between March 2020 and May 2022.

Cutaneous immune-related adverse events: incidence rates, risk factors and association with extracutaneous toxicity - a prospective study of 189 patients treated with checkpoint inhibitors at a Spanish tertiary care hospital.

Background: Clinicians are increasingly prescribing immune checkpoint inhibitors (ICIs) to treat cancer, but the real-world incidence, characteristics and risk factors of cutaneous immune-related adverse events (cirAEs) are unclear.

Objectives: To determine the incidence, features and risk factors of cirAEs and to measure their possible association with extracutaneous toxicity.

Methods: We conducted a prospective observational study in a Spanish tertiary care hospital, including people who started an ICI between March 2020 and May 2022.

A Case Series of 18 Congenital Haemangiomas: Clinical, Histological and Ultrasound Features, and their Relationship with Complications and Atypical Behaviour.

Recent studies have advanced our understanding of the clinical, histological and imaging characteristics of congenital haemangiomas (CHs), and have reported possible complications and atypical behaviour. The aim of this study is to describe the clinical, histological and ultrasound features of a series of CHs and to analyse their association with complications and atypical behaviour, with a view to providing diagnostic and management recommendations. The medical records, histology results and ultrasound images of all patients with CH diagnosed in the Dermatology Department of Alicante University General Hospital between 2006 and 2021 were retrospectively reviewed.

Proposal of a clinically relevant working classification of pituitary neuroendocrine tumors based on pituitary transcription factors.

The immunohistochemistry (IHC) characterization of pituitary transcription factors (PTFs) PIT1, TPIT, and SF1, which enable the identification of three different adenohypophyseal cell lines, has been incorporated into the latest classification system of the World Health Organization (WHO) for pituitary adenomas. This change overturns the concept of the adenoma as solely a hormone producer and classifies these tumors based on their cell lineage. The aim of the study was to provide a diagnostic algorithm, based on IHC expression of hypophyseal hormones with potential use in diagnostic practice, contributing to an improved classification of pituitary adenomas.

[Microglandular adenosis of the breast in a patient with a history of mediastinal radiotherapy].

The risk of secondary tumors in patients who have received mediastinal radiation therapy is well-known. Microglandular adenosis of the breast is a rare lesion that is considered benign, although its possible role as a precursor of invasive breast carcinoma has been considered. We present a case of microglandular adenosis in a patient who received mediastinal radiation therapy in childhood for Hodgkin's lymphoma.

Plexiform Xanthomatous Tumor, Variety of Xanthoma or Subtype of Fibrohistiocytic Tumors?

Plexiform xanthomatous tumor was proposed as an independent neoplasm within fibrohistiocytic tumor group a few years ago. The arguments were based on their different clinical features as well as their own morphological and immunohistochemical findings. Nevertheless, it has not been widely studied yet, and there are few reports about this entity.

Cardiac Tamponade Associated with the Presentation of Anaplastic Large Cell Lymphoma in a 2-Year-Old Child.

The anaplastic large cell lymphoma is a rare entity in pediatric patients. We present an unusual case of pericardial involvement, quite uncommon as extranodal presentation of this type of disorder, that provoked a life-risk situation requiring an urgent pericardiocentesis. To our knowledge, this is the first report on a child with pericardial involvement without an associated cardiac mass secondary to anaplastic large cell lymphoma in pediatric age.
