Abstract Background Dysphagia is the main symptom of adult EoE. We describe a novel syndrome, referred to as “Food‐induced Immediate Response of the Esophagus” (FIRE), observed in EoE patients. Methods FIRE is an unpleasant/painful sensation, unrelated to dysphagia, occurring immediately after esophageal contact with specific foods. EoE experts were surveyed to estimate the prevalence of FIRE, characterize symptoms and identify food triggers. We also surveyed a large group of EoE patients...

ABSTRACT The advent of biologic therapies has transformed care for severe atopic disorders but their high cost poses new challenges with regards to long‐term sustainability and fair allocation of resources. This article covers the basic concepts of cost‐utility analyses and reviews the available literature on cost‐utility of biologic drugs in atopic disorders. When used within their limits as part of a multi‐dimensional assessment, economic analyses can be extremely useful to guide decision‐making...

Abstract The pandemic condition Coronavirus‐disease (COVID‐19), caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) can take asymptomatic, mild, moderate, and severe courses. COVID‐19 affects primarily the respiratory airways leading to dry cough, fever, myalgia, headache, fatigue, and diarrhea and can end up in interstitial pneumonia and severe respiratory failure. Reports about the manifestation of various skin lesions and lesions of the vascular system in some subgroups...

Malignant mesothelioma can be difficult to distinguish from other malignancies, particularly non–small cell lung carcinomas (NSCLCs), without immunohistochemistry. However, conventional markers of mesothelial lineage all have variable degrees of cross-reactivity with other neoplasms, including NSCLCs, necessitating the use of multiple mesothelioma and carcinoma markers in every case for accurate diagnosis. A recently described monoclonal HEG homolog 1 (HEG1) antibody was proposed to be a specific...

Endocrine mucin-producing sweat gland carcinoma (EMPSGC) is a rare, low-grade adnexal neoplasm with predilection for the periorbital skin of older women. Histologically and immunophenotypically, EMPSGC is analogous to another neoplasm with neuroendocrine differentiation, solid papillary carcinoma of the breast. Both lesions are spatially associated with neuroendocrine mucinous adenocarcinomas of the skin and breast, respectively. EMPSGC is ostensibly a precursor of neuroendocrine-type mucinous sweat...

Recently, the American Joint Committee on Cancer (AJCC) updated the staging system for penile squamous cell carcinoma. According to it, unlike its previous version, the involvement of urethra does not upstage the tumor; however, the involvement of corpora cavernosa (CC) does. The tumors involving CC are now staged pT3, whereas those involving corpora spongiosa (CS) are staged pT2, irrespective of the involvement of the urethra. In the current study, we sought to validate these recent modifications...

A robust morphomolecular classification system for gastric carcinoma is required. A 4-tier morphologic classification is proposed, including diffuse, intestinal, tubular, and lymphoid types. A tissue microarray for mismatch repair immunohistochemistry and Epstein-Barr virus (EBV) in situ hybridization were performed in 329 gastric carcinomas. DNA flow cytometry was used to detect aneuploidy in formalin-fixed paraffin-embedded samples. Lymphoid histology was the third most common histologic pattern...

To date, the apocrine variant of lobular carcinoma in situ (AP-LCIS) has been cursorily described as a subtype of lobular carcinoma in situ (LCIS). We retrospectively reviewed 34 cases of AP-LCIS (including 23 associated with invasive lobular carcinoma) to fully characterize it. AP-LCIS typically presented with screen-detected calcifications in older women (mean age: 65 y) and was characterized by distended terminal duct lobular units with relatively large “pleomorphic” cells, central necrosis, and...

Acquired cystic disease of kidney–associated renal cell carcinoma (ACD-RCC) is a distinct subtype of renal cell carcinoma with unique morphologic and clinicopathologic features. Generally, ACD-RCC is regarded as an indolent tumor; however, prognostic and outcomes data have been conflicted by the limited and relatively low number of cases with patient follow-up or adverse events. In this study, we focused on the histology of metastatic lesions and identifying prognostic factors associated with metastatic...

The absence of neuroendocrine (NE) cells in the intestinal mucosa in autoimmune enteropathy (AIE) has been occasionally reported. However, the status of NE cells has not been studied in detail in AIE. Small bowel and colonic biopsies were retrospectively retrieved from 18 AIE patients (26 baseline [18 small bowel and 8 colon]; and 15 follow-up [11 duodenum and 4 colon] biopsies in 11 patients). Thirty-three common variable immunodeficiency (CVID) patients (30 small bowel and 16 colon), 15 inflammatory...

Prostatic-type differentiation in the lower female genital tract is encountered rarely and its causes and clinical associations are not well established. Within the vagina, reports to date have invariably described ectopic prostatic-type differentiation as restricted to the lamina propria. We recently encountered a patient receiving testosterone for gender dysphoria whose vaginectomy specimen showed a prostatic glandular proliferation within the surface epithelium. To elucidate its potential association...

Five years after the last prostatic carcinoma grading consensus conference of the International Society of Urological Pathology (ISUP), accrual of new data and modification of clinical practice require an update of current pathologic grading guidelines. This manuscript summarizes the proceedings of the ISUP consensus meeting for grading of prostatic carcinoma held in September 2019, in Nice, France. Topics brought to consensus included the following: (1) approaches to reporting of Gleason patterns...

The prevalence and significance of programmed death-1 ligand (PD-L1) expression in different types of tubo-ovarian carcinoma have not been well defined. We evaluated PD-L1 expression and CD8+ tumor-infiltrating lymphocyte (TIL) density in whole tissue sections of 189 cases of tubo-ovarian carcinoma, including high-grade serous carcinoma (HGSC, n=100), clear cell carcinoma (CCC, n=24), endometrioid carcinoma (EmC, n=40), and mucinous carcinomas (MC, n=25). Using the tumor proportion score (TPS) with...

Mixed endometrial carcinomas are defined as a combination of 2 or more distinct histologic subtypes, one of which must be a type II tumor comprising at least 5% of the tumor volume. The oncogenesis of these tumors remains unclear, particularly in light of the increasingly appreciated morphologic overlap among subtypes, as well as evolving molecular data. We evaluated 8 cases of mixed endometrial carcinoma, including 4 endometrioid (EC)/serous (SC), 1 SC/clear cell (CC), and 3 EC/CC cases, to study...

Systemic Epstein-Barr virus–positive T-cell and natural killer (NK)-cell lymphoproliferative diseases of childhood are a group of lethal diseases mostly affecting children and young adults. The Ohshima Grading System and the 2017 World Health Organization (WHO) classification have been used for classifying this spectrum, but these systems have not been validated externally and compared. Therefore, we examined 36 cases of systemic Epstein-Barr virus–positive T-cell and NK-cell lymphoproliferative...

Congenital pulmonary airway malformations (CPAMs) are abnormalities of the lung arising during development. At our institution the majority of type I infantile CPAMs contain mucinous cell clusters (MCCs). The overlapping histology of MCCs and adult in situ mucinous adenocarcinomas, as well as reports of metastatic mucinous adenocarcinoma arising in CPAMs resected later in childhood raise concerns about the malignant potential of these cells. However, after adequate surgical resection, malignant recurrence...

Common variable immunodeficiency (CVID) and selective immunoglobulin A deficiency (IgAD) often cause chronic lung disease, but the pulmonary pathologic features of these systemic diseases are poorly recognized by pathologists. It has been claimed that CVID cases show a characteristic combination of noncaseating granulomas-lymphoid proliferations termed granulomatous-lymphocytic interstitial lung disease (GLILD). We present 34 surgical lung biopsy cases of CVID and 4 of IgAD. Noncaseating granulomas...

Intestinal inertia is a severe form of gut dysmotility that may require surgical resection. Loss of myenteric ganglion cells has been proposed as a possible etiology. Preclinical models have also suggested that virus infection-associated ganglionitis may be an alternative pathogenic factor. We determined to the extent intestinal inertia is associated with the lack of myenteric ganglion cells or ganglionitis using resection specimens from 27 intestinal inertia and 28 colon cancer patients. A hot spot...

Some recent reports suggested that many Sertoli cell tumors, not otherwise specified (SCTs-NOS) of the testis were analogs of the solid pseudopapillary neoplasm (SPN) of the pancreas. One of the most relied on pieces of information for this assertion was the shared occurrence in both neoplasms of exon 3 mutations of the CTNNB1 gene, which was reflected by nuclear β-catenin expression. We, therefore, compared the morphologic and immunohistochemical features of 18 SCTs-NOS with strong, diffuse nuclear...

In-hospital transmission is one of the main routes of the 2019 novel coronavirus (SARS-CoV-2) spreading among health care workers (HCWs) who are the frontline fighters. However, coming into contact with COVID-19–positive patients is unavoidable. Therefore, hand hygiene is of utmost importance for the prevention of COVID-19 among HCWs. This purpose can be achieved by applying alcohol-based hand rubs, washing hands properly with soap and water, and applying other antiseptic agents. Nevertheless, regular...

Burning mouth syndrome (BMS) is a condition that remains a diagnostic challenge and is frequently difficult to treat. Rather than being a singular entity, more recent research has suggested that the diagnosis of BMS encompasses a family of syndromes. Of this family, type 3 has been identified as being related to contact dermatitis. Although this subtype has been most commonly associated with dental allergens, several food, cosmetic, and pharmaceutical products have also been identified as allergens...

Topical corticosteroid therapies are widely utilized, despite the controversial results of corticoid therapy in irritant contact dermatitis as a local inflammatory reaction after repeated or single skin exposure to a chemical substance. Although corticoids may reduce the inflammatory response to the irritant, their antiproliferative effects may reduce skin barrier recovery while allowing further penetration of irritants if exposure continues. This overview reexamines the efficacy of corticosteroids...

The role of Staphylococcus aureus (SA) in the pathogenesis and management in atopic dermatitis is rapidly evolving. The modern understanding of SA in atopic dermatitis now includes an expanded array of virulence factors, the interplay of clonal and temporal shifts in SA populations, and host factors such as filaggrin and natural moisturizing factor. New, emerging therapies that focus on long-term, targeted elimination of SA colonization are currently under investigation (Br J Dermatol 2017;17(1)63–71)....

Background Methylchloroisothiazolinone/methylisothiazolinone (MCI/MI) allergy has increased for the last decade, mostly not only because of high concentrations in cosmetics but also because of its use as a biocide in industrial settings. Objective We report an outbreak of allergic contact dermatitis in 8 workers at a water bottling plant secondary to excess levels of MCI/MI in the cooling system, found to be at levels 5 times the manufacturer's recommendations. Methods Of 15 workers...
