A 73-year-old female with a 6-month history of progressive dysphagia and chest pain was referred to our hospital. She underwent esophagogastroduodenoscopy, which revealed abnormally strong contractions in the distal esophagus. Esophageal biopsy specimens showed massive eosinophil infiltration into the epithelium, and high-resolution manometry (HRM) also demonstrated abnormally strong contractions in the distal esophagus. Based on these results, she was diagnosed with Jackhammer esophagus (JHE) due to eosinophilic esophagitis (EoE)...

A 4-year-old captive ringed seal (Pusa hispida) was treated with subcutaneous antibacterial injections for pus exuding wounds in the skin and associated blubber following a bite attack. Three months after the incident, the animal presented nystagmus and died the following day. At necropsy, there was a 25 × 18 × 25 mm well-delineated, opaque nodular mass in the lung, besides the skin ulcers and localized areas of discoloration in the blubber correlating with the bite wound and injection sites. Histopathology of the pulmonary mass demonstrated severe eosinophilic inflammatory infiltration among numerous intralesional fungal hyphae...

Dear Editor, Gestational pemphigoid (GP) is a rare autoimmune bullous dermatosis in pregnancy. GP usually occurs during the second or third month of pregnancy. It clinically manifests as the development of either early-onset urticarial lesions or late-onset subepidermal blisters that may linger for weeks or even months. Herein we report the case of a 45-year-old woman with the distinctive clinical onset of GP. A forty-five-year-old woman, gravida I, para 0, at 27 weeks gestation, was referred for evaluation to our Department with an extensive pruritic eruption that had developed over the previous 7 days...

BACKGROUND AND AIMS: Eosinophilic esophagitis (EoE) is a chronic-inflammatory disease characterized clinically by symptoms of esophageal dysfunction and histopathologically by a prominent eosinophilic inflammation. Despite eosinophils having histologically a pre-dominant position, their role in the immunopathogenesis of the disease is still questionable. Several other inflammatory cells are involved and may play a critical role as well. The purpose of this study was to characterize the mast cell infiltration, and to correlate it with clinical state of EoE...

Eosinophils induce inflammation by releasing cytokines and cytotoxic granule proteins. Infiltration of eosinophilic granulocytes occurs in the outer membrane of chronic subdural hematomas (CSDHs). Eosinophils play an important role in the growth of CSDHs. However, the manner in which eosinophils accumulate within CSDH fluid remains undetermined. In the current study, we assessed the expression of eosinophil chemoattractants in CSDH fluids according to the growth stage of the CSDHs and examined the correlation between the two...

The profile of activation of lipid mediator (LM) pathways in asthmatic airway inflammation remains unclear. This experimental study quantified metabolite levels of ω3-, ω6- and ω9-derived polyunsaturated fatty acids in bronchoalveolar lavage fluid (BALF) after 4-weeks of repeated house dust mite (HDM) exposure in a murine (C57BL/6) asthma model. The challenge induced airway hyperresponsiveness, pulmonary eosinophil infiltration, but with low and unchanged mast cell numbers. Of the 112 screened LMs, 26 were increased between 2 to >25-fold in BALF with HDM treatment (p < 0...

A definitive diagnosis of Langerhans cell histiocytosis (LCH) requires a combination of clinical presentation, histology, and immunohistochemistry. The inflammatory infiltrate contains various proportions of LCH cells, the disease hallmark, which are round and have characteristic "coffee-bean" cleaved nuclei and eosinophilic cytoplasm. Positive immunohistochemistry staining for CD1a and CD207 (langerin) are required for a definitive diagnosis. Isolated cutaneous disease should only be treated when symptomatic, because spontaneous resolution is common...

Myotonic dystrophy (MD) frequently involves the gastrointestinal tract, where it can manifest as chronic intestinal pseudo-obstruction (CIPO), particularly in adults. This manifestation is quite uncommon in children. We report the case of a 12-year-old boy with MD type 1 and CIPO, in which a pathologic assessment revealed an association with smooth muscle α-actin deficiency in the external muscular layer of the ileum, and with features of eosinophilic plexitis and eosinophilic muscle infiltration in the colon...

BACKGROUND: Aetiology of heart failure (HF) often remains obscure. We therefore evaluated the usefulness of a combined diagnostic approach including cardiac magnetic resonance imaging (CMRI) and endomyocardial biopsy (EMB) to assess the cause of unexplained cardiomyopathy underlying HF. METHODS AND RESULTS: We retrospectively investigated 100 consecutive patients (36% women, mean age 53.6 ± 18.8 years) presenting with unexplained cardiomyopathy (HF with reduced ejection fraction or left ventricular hypertrophy; excluding ischaemic and valvular heart disease; left ventricular ejection fraction 31...

A 65-year-old lady and a 69-year-old gentleman, both with a background history of adult-onset asthma, presented with clinical features of heart failure (HF). High-sensitivity cardiac troponin T and eosinophils were significantly raised, along with poor left ventricular (LV) systolic function on cardiac imaging. Endocardial and skin biopsy (in cases 1 and 2, respectively) showed eosinophilic infiltration. This in combination with the clinical features confirmed the diagnosis of eosinophilic myocarditis (EM) secondary to eosinophilic granulomatosis with polyangiitis in case 1...

Background: Autoimmune subepidermal bullous dermatoses have similar clinical features to those of a spectrum of immune reactants at the dermoepidermal junction (DEJ). It is difficult to obtain a precise diagnosis without an immunofluorescence assay because of their similar clinical presentations. The aim of this study was to describe the cellular cutaneous infiltration among autoimmune subepidermal bullous dermatoses. Materials and methods: This retrospective analysis was conducted at a hospital in Riyadh, Saudi Arabia using biopsy-based data collected from 65 patients...

Background: Oral squamous cell carcinoma (OSCC) is the most common cancer of oral cavity. Tumor stage, thickness, lymph node metastasis (LNM), extranodal spread, perineural invasion, tumor differentiation, mutations, human papillomavirus infection, and tumor microenvironment are independent prognostic indicators of OSCC. However, clinically, among all factors, LNM is considered an important prognostic factor in OSCC as it not only determines the stage of disease but also the strongest independent factor which predicts recurrence of disease...

Aims: Atherosclerosis is characterised by the abundant infiltration of myeloid cells starting at early stages of disease. Myeloid cells are key players in vascular immunity during atherogenesis. However, the subsets of vascular myeloid cells have eluded resolution due to shared marker expression and atypical heterogeneity in vascular tissues. We applied the high-dimensionality of mass cytometry to the study of myeloid cell subsets in atherosclerosis. Methods and Results: Apolipoprotein E-deficient (ApoE-/-) mice were fed a chow or a high fat (western) diet for 12 weeks...

Eosinophil infiltration is considered a hallmark in allergic airway inflammation, and the blockade of eosinophil differentiation may be an effective approach for treating eosinophil-related disorders. Mammalian target of rapamycin (mTOR) is a vital modulator in cell growth control and related diseases, and we have recently demonstrated that rapamycin can suppress eosinophil differentiation in allergic airway inflammation. Considering its critical role in haematopoiesis, we further investigated the role of mTOR in eosinophil differentiation in the context of asthmatic pathogenesis...
