Pterygium is a common lesion consisting of fleshy conjunctival growth extending towards the cornea. There is no documented risk of malignant transformation; however, concomitant disease is not rare, and its link to sunlight exposure indicates a risk of other malignancies. The purpose of our study is to describe histopathological features of resected pterygiums and to recognize patients at risk of other conjunctival diseases. One hundred and forty-nine formalin-fixed and paraffin-embedded pterygium samples were subjected to histopathological analysis. Histological H&E sections were obtained and digitalized using a Zeiss Axio Scan.Z1 slide scanner. Thirteen predefined morphological features were used to record histopathological changes in the epithelium and substantia propria. Neovascularization was observed in 54% of the samples. Sun damage, comprising solar elastosis and stromal plaque, was present in 81% of the samples. Variation in epithelial thickness was the most common change, with acanthosis and atrophy being observed in 62% and 26% of the samples, respectively. In our series, 21% (31/149) of pterygiums showed mild to moderate dysplasia, a finding that may be associated to ocular surface squamous neoplasia (OSSN). Moreover, 32% (47/149) of the cases showed melanocytic hyperplasia, which could represent primary acquired melanosis (PAM). There is a positive correlation between dysplasia and chronic inflammation p = 0.012 and an inverse correlation with epithelial atrophy p = 0.001 and neovascularization p = 0.05 . Similarly, a positive correlation is observed between goblet cell hyperplasia and melanocytic hyperplasia p = 0.02 . Our findings show that pterygiums harbour histological features that may be suggestive of OSSN or PAM in 53% of our patients. Whilst being on the benign side of the spectrum, these two entities are known for their potential progression to malignancy. A recommendation is made for all surgically excised pterygiums to be sent for histopathological diagnosis, and clear guidelines for reporting of these lesions should be established. Associated histopathological findings suggestive of other concomitant diseases should be identified to insure adequate follow-up of these patients.

Background: Several dermoscopic features of juvenile xanthogranuloma (JXG) have been previously described in single cases or small case series and need to be further verified in a large sample.Objective: We aimed to investigate the dermoscopic patterns of JXG in a large case series and the correlations of these with clinical features of different histopathological subtypes of JXG.Methods: Patients who underwent dermoscopic evaluation and had a histopathological diagnosis of JXG were recruited. Histological findings, including stage and Ki67 proliferative index and the dermoscopic features of each lesion were recorded.Results: Forty-one patients with JXG were included. The male to female ratio was 1.28: 1 and the median age of onset was 11 months (range: 0–95 months). Fourteen lesions were histologically categorized in the early stage, 17 in the developed stage, and 10 in the late stage. The “setting sun” pattern was observed in 35 lesions (85.4%) and “clouds” of paler yellow areas in 26 lesions (63.4%). The frequency of the “setting sun” pattern was higher in the early and developed stages (30/31) than in the late stage (5/10) (P = 0.002), while that of “clouds” of paler yellow areas was not significantly different between each stage. Branched linear vessels were detected in the early (11/14) and developed stage (6/17), but not in the late stage. The mean Ki67 index of the lesions with linear vessels was 11.8% (range: 2–40%), which was higher than that of lesions without linear vessels (mean index: 5%, range: 1–30%) (P = 0.005). The pigment network and whitish areas were only detected in 6 and 5 lesions in the late stage, respectively. The whitish areas presented either as streak or stellate shape. The pigment network exhibited either in a centric or a peripheral pattern.Conclusions: The “setting sun” pattern is the characteristic dermoscopic features of JXG in the early and developed stages, while whitish areas and pigment network are the characteristic patterns in the late stage. Linear vessels present as branched patterns and mostly occur in the early stage with a high proliferative index, indicating rapid growth. The whitish areas and pigment network may present in various patterns. Dermoscopy is a useful adjunctive tool in the diagnosis and staging of JXG.

Localized juvenile spongiotic gingival hyperplasia is a relatively new histopathological diagnosis, presenting as a localized erythematous lesion of the anterior attached gingivae. Presenting in a peri-pubertal age, this condition is often misdiagnosed as ‘puberty gingivitis’. Here, two cases presenting to the Joint Paediatric-Oral Medicine clinic at the Eastman Dental Hospital are discussed. CPD/Clinical Relevance: Localized juvenile spongiotic gingival hyperplasia is a novel diagnosis, and one that is currently under-reported. Increased awareness of this condition is required for appropriate patient management.

Chimeric antigen receptor T (CART) cell therapy is highly effective for relapsed/refractory hematologic malignancy [1,2]; however, cytokine release syndrome (CRS) and neurotoxicity are observed in up to 77% of patients [3]. In large case series, the most common presentations of neurotoxicity were encephalopathy (57%), headache (42%), tremor (38%) and aphasia (35%). CART mediated spinal cord toxicity is not well characterized. Structural neurologic damage (stroke and intracranial hemorrhage) was only observed in 1-2% and seizures were seen in 1%-8% of cases [3, 4]. Neuroimaging findings in patients with neurotoxicity are rare and not specific.

Abstract Background In recent years, the endometriosis has overcome a noteworthy renaissance in the recognition of its potential. In certain patients, a demonstrable malignant progression of ectopic foci leading to development of ovarian cancer is seen. The knowledge of endometriosis overthrow background into endometriosis associated ovarian cancer is of paramount importance for selection of patients at risk. The goal of the presented study was to review a malignant potential of the endometriosis and to specify predictive factors of endometriosis progression into ovarian cancer. Altogether 189 patients were included in the study. Conventional cytogenetics as well as measurement of transcriptional activity of CTNNB1 (β-catenin) and HIF1A (HIF1-α) genes were prospectively studied in 60 endometriosis patients and 50 control group patients. The retrospective histopathological analysis was performed in 19 endometriosis associated ovarian cancer patients and 60 patients with histologically confirmed endometriosis. Results Five endometriosis patients showed a deviation from normal cytogenetics finding without affecting of their phenotype. In 6 cases of endometriosis associated ovarian cancer ectopic endometrium was not confirmed. The remaining 13 cases demonstrated either benign or atypical endometriosis or even structures of borderline carcinoma. Atypical endometriosis was histologically confirmed in 20% of 60 endometriosis patients. Determination of gene expression (CTNNB1, HIF1A) formed two subgroups. Transcriptionally incipient endometriosis subgroup with insignificant genes expression compared to control group. In transcriptionally evident endometriosis subgroup were genes expressions significantly higher compared to control group (p < 0.01) as well as transcriptionally incipient endometriosis subgroup (p < 0.05). Conclusions Significant structural abnormalities of chromosomes are not included in genetic rigging of endometriosis patients. Atypical endometriosis represents a histopathologically detectable intermediate of endometriosis progression. Determination of genes expression CTNNB1 and HIF1A helps to allocate risk patients with endometriosis where more precise management is needed.

Fecal microbiota transplantation (FMT), which has been established as the standard treatment for recurrent <i>Clostroides</i> difficile infection, may also play a role in the management of other diseases associated with dysbiosis of the gut microbiota. To ensure efficacy and safety of FMT, an appropriate donor screening process is required. The main purpose of donor screening is to check for infectious diseases that could be transmitted to the recipient. The screening process involves a medical history questionnaire, and blood and stool testing. Several randomized clinical trials and large case series on FMT reported no, or few, adverse events related to infection by following this donor screening process. However, there is still concern over the transmission of antibiotic-resistant bacteria. In addition, a low donor acceptance rate due to rigorous screening makes donor recruitment difficult, and also imposes a significant cost burden. A consensus on the most crucial elements of donor screening is needed for wide application of FMT.

Aim: To outline various histopathological types of ovarian cysts received in our teaching hospital along with their prevalence and mode of presentation and to assess the proportion of physiologic versus pathological cysts and benign versus malignant ovarian cysts. Duration of study: From Jan 2019 to March 2021. Methods: Histopathology Department of Bakhtawar Amin Medical & Dental College & Hospital, Multan. A retrospective review of 122 ovarian lesions including physiological/functional cysts, pathological non neoplastic cysts as well as benign, borderline and malignant neoplasm. Histopathology reports of all ovarian specimens were reviewed and counted. Details like age, marital status, parity, presenting complaints, procedure opted, laterality, size, gross and microscopic details and final histological diagnosis etc were recorded. H&E stained slides of all cases were reviewed. In difficult suspicious cases, immunohistochemistry was also carried out. Percentage and proportions were calculated for all the variables. Relevant tables and charts were computed. Results: A total of 122 ovarian specimens with some lesion were segregated in histopathology department of Bakhtawar Amin Hospital from 117 patients with 5 patients having bilateral lesions. The mean age was 33.2 years (ranging from 13-71 years). Most ladies presented between 25-45 years of age. Out of these 117 patients, 18 ladies were unmarried. Out of the 99 married, 12 were nulliparous. Sixty four ladies (54.7%) found to have cysts/neoplasm in right sided ovary, forty eight (41%) presented with left sided ovarian involvement and 5 (4.3 %) presented with bilateral ovarian lesions. Conclusion: Non neoplastic ovarian cysts are more frequent as compared to neoplastic masses. Histopathological diagnosis is mandatory for final confirmatory diagnosis.
