Unlabelled: is an emerging fungal pathogen notable for its resistance to multiple antifungals and ability to survive in various environments. Understanding the interactions between and environmental protozoa, such as could provide insights into fungal adaptability and pathogenicity. Two isolates (MMC1 and MMC2) were co-cultured with to examine interaction dynamics, survival, stress responses, growth, virulence, biofilm formation, and antifungal susceptibility.

The 2020 WHO classification has provided a comprehensive framework for the categorization of endometrial carcinoma. However, it has not fully addressed the spectrum of uncommon entities that are currently not recognized by the 2020 WHO and have only been described in the form of small case series and case reports.

The importance of humoral immunity to fungal infections remains to be elucidated. In cryptococcosis, patients that fail to generate antibodies against antigens of the fungus Cryptococcus neoformans are more susceptible to the disease, demonstrating the importance of these molecules to the antifungal immune response. Historically, antibodies against C.

Morphological analysis via transmission electron microscopy revealed slightly larger Neff EVs (average = 194.5 nm) compared to more polydisperse T4 EVs (average = 168.

However, Pap smear examination can be challenging, being based on the observer ability to decode different cytological and architectural features. This study aims to evaluate the malignancy rate of AGC (atypical glandular cells) category, investigating the relationships between cytological and histological diagnosis.

SLN is routinely analyzed by ultrastaging and immunohistochemistry. The aim of this study was to assess the survival of patients undergoing SLN analyzed by one-step nucleic acid amplification (OSNA) compared with ultrastaging.

We enrolled 244 patients affected by LACC and treated with CT-RT followed by surgery in order to assess the prognostic role of the histological response using the Mandard scoring system. Results: A complete pathological response (TRG 0) was observed in 118 patients (48.

Current literature data suggest a favorable prognosis of breast MCAs despite its immunoprofile usually revealing lack of expression of estrogen receptor, progesterone receptor and HER-2 and high Ki67. As far as we know, only 36 cases have been reported in the literature to date.

The diagnosis of CE is based on the histological evidence of stromal plasma cells; however, standardized methods to assess plasma cells are still lacking. In the present paper, we aimed to determine the most appropriate plasma cell threshold to diagnose CE based on pregnancy outcomes.

A 45-year-old woman underwent surgery due to an advanced bilateral adnexal carcinoma with peritoneal and appendiceal metastases. Histological examination revealed an HGSC exhibiting a distinct sertoliform component.

This phenomenon has previously been described in several tumors, such as neuroblastomas, testicular malignancies, renal cell carcinomas, melanomas, and lymphomas. Spontaneous remission has also been documented in breast cancer; however, it represents an extremely rare and poorly understood phenomenon, with only a few reported cases in the literature.

However, given the high mortality and recurrence rate of cervical cancer, novel parameters that are able to provide additional prognostic information are needed in order to allow a better prognostic stratification of cervical cancer patients.
Methods: A search was conducted on PubMed to identify relevant literature data regarding prognostic factors in cervical cancer.
Collision tumors are rare and very few cases were described in which collision was revealed in a metastatic lesion. Herein we report a case of woman with a peritoneal carcinomatosis underwent to bioptic procedure in correspondence of a nodule of Douglas peritoneum with clinical suspect of ovarian/uterine origin. Histologic examination revealed two different colliding epithelial neoplasms: an endometrioid carcinoma and a ductal breast carcinoma, the latter not suspected at the time of biopsy.

Herein, we described a case of ovarian PiMHEC, comparing it to endometrial PiMHEC and assessing previously published cases of putative ovarian PiMHEC. A 65-year-old woman underwent hysterectomy for an ovarian tumor characterized by solid nests of basaloid cells with prominent ghost cell keratinization.

We investigated the prevalence of persistent symptoms amongst children and assessed the risk factors, including the impact of variants. A prospective cohort study included children (≤18 years old) with PCR-confirmed SARS-CoV-2 infection.

The recurrent tumor increased in volume during chemotherapy. Postchemotherapy histologic examination showed a pure mucinous signet-ring cell pattern with positivity for cytokeratin 20 and CDX2, focal SATB2 expression and negativity for cytokeratin 7 and estrogen and progesterone receptors.

We compared these HLTCs to similar cells found in microcystic, elongated and fragmented (MELF) pattern (n = 20) or after neoadjuvant chemotherapy (NAC) (n = 5). The four cases were endometrioid, serous, clear cell, and gastric-type; all were at FIGO stage ≥ III.

We aimed to assess the association between L1CAM expression, the MELF pattern, and lymph node status in endometrial carcinoma. Consecutive cases of endometrial carcinoma with MELF pattern were immunohistochemically assessed for L1CAM.

In the present study, we conducted a systematic review and metanalysis of literature data in order to determine if PNI could be an independent prognostic predictor of patient's survival in VSCC. Four electronic databases (PubMed, ISI Web of Science, Scopus and Google Scholar) were searched from their inception to December 2021 for all studies assessing the prognostic value of PNI in VSCC.

Methods: Twenty cases of MorM with areas of cytoplasmic clarification were assessed by immunohistochemistry for HNF1β, Napsin A, and P504S/alpha-Methylacyl-CoA racemase (AMACR); 60 tumors were selected as controls (20 classical MorM, 20 conventional squamous differentiation and 20 CCC).
Background: Emerging evidence shows that both adults and children may develop post-acute sequelae of SARS-CoV-2 infection (PASC). The aim of this study is to characterise and compare long-term post-SARS-CoV-2 infection outcomes in adults and children in a defined region in Italy.
Methods: A prospective cohort study including children (≤18 years old) with PCR-confirmed SARS-CoV-2 infection and their household members.
Background: chemotherapy response score (CRS) is widely used to assess the response of ovarian high-grade serous carcinoma (HGSC) to chemotherapy and is based on pathological examination of omental specimens. We aimed to assess the prognostic value of CRS assessed on the uterine adnexa. Methods: a systematic review and meta-analysis were performed by searching three electronic databases from 2015 inception to September 2021.
