Abstract Background and study aims Linked color imaging (LCI) is a new image-enhancing technique that facilitates the differentiation of slight differences in mucosal color tone. We performed an exploratory analysis to evaluate the diagnostic capability of LCI in ultraslim endoscopy, using data from patients examined in the LCI-Further Improving Neoplasm Detection in upper gastrointestinal (LCI-FIND) trial, a large-scale, multicenter, randomized controlled trial that demonstrated the capability of LCI for detecting neoplastic lesions in the upper gastrointestinal tract. Patients and methods Data from the LCI-FIND prospective trial were used. In the LCI-FIND trial, 1502 patients with a history of gastrointestinal cancer were randomly assigned to two groups based on examination methods: white light imaging (WLI) followed by LCI (WLI group) and LCI followed by WLI (LCI group). The present exploratory analysis investigated the outcomes of patients who underwent ultraslim and standard endoscopies. Results Ultraslim endoscopes were used in 223 patients and standard endoscopes in 1279 patients. The primary endpoint of the LCI-FIND trial was the percentage of patients diagnosed with a neoplastic lesion using WLI or LCI. The corresponding percentage tended to be higher with LCI than with WLI among patients who underwent ultraslim endoscopy and among those who underwent standard endoscopy; the crude risk ratio was 2.21 [95 % confidence interval (CI): 1.06–4.67], and the adjusted odds ratio was 2.46 (95 % CI: 1.07–5.63). Conclusions Our exploratory analysis of data from the LCI-FIND trial showed that LCI is useful in identifying neoplastic lesions, when used in ultraslim endoscopy.

Introduction: Urinary bladder is a site of various non-neoplastic and neoplastic lesions, both of which can present with hematuria. Cystoscopy allows for direct visualization of the bladder mucosa and also obtaining tissue for histopathologic evaluation. The most common non-neoplastic and neoplastic lesion of the urinary bladder is non-specific cystitis and urothelial carcinoma respectively. Materials and methods: This study is a 4-year retrospective study conducted in the Department of Pathology at Patan Hospital, Nepal. All cases from the urinary bladder i.e., both cystoscopic and cystectomy samples were included in the study. Hematoxylin and eosin-stained slides were re-evaluated whenever required. Results: A total of 145 cases were included which consisted of 17 cystectomy specimens and 128 cystoscopic biopsies. There was a male predominance. The non-neoplastic and neoplastic cases consisted of 32% and 68% respectively. Chronic non-specific cystitis and high-grade infiltrating urothelial carcinoma were the most common non-neoplastic and neoplastic lesions respectively. 56.1% of cystoscopic biopsies had the presence of detrusor muscle with 21.7% showing its invasion. Conclusions: Urinary bladder lesions have a wide spectrum ranging from non-neoplastic to neoplastic conditions. The presence of detrusor muscle in a cystoscopic biopsy, and its evaluation for invasion helps in diagnosis and further planning of patient management.

Background: Central nervous system (CNS) lesions show considerable geographic and racial variations with respect to the incidence and their pattern of distribution. CNS neoplasm account for 2% of all cancers. There has been a rapid increase in incidence of CNS tumors. Many non-neoplastic CNS lesions can clinically and radiologically mimic brain tumors and to differentiate them histopathological examination is necessary.Methods: This was a descriptive cross-sectional study of 30 cases, carried out from March 2020 to February 2021, in a tertiary health care hospital. The cases were diagnosed histopathologically and categorized according to the WHO 2021 classification.Results: The study included 30 cases. 3 (10%) of them were non-neoplastic while 27 (90%) were neoplastic with glioblastoma and diffuse astrocytoma being the most common. Overall, tumors of neuroepithelial tissue (60%) was the most common entity. Frontal lobe was the most commonly observed site in the neoplastic lesion. Headache was the most common presentation. Age range varied from 7 years to 66 years with the mean age of 32.7 years.Conclusions: The spectrum of neoplastic lesions were astrocytoma, glioblastoma, ependymoma, hemagioblastoma, medulloblastoma, meningioma, non-hodgkins lymphoma, oligodendroglioma, pitutary adenoma, schwannoma and non-neoplastic were A-V malformation, brain abscess, subdural empyema.

Masson's tumour, also known as intravascular papillary endothelial hyperplasia, is a rare non-neoplastic lesion of vascular origin, caused by an excessive reactive proliferation of endothelial cells in normal blood vessels or vascular malformations. It can affect any part of the body, presenting most frequently in the vessels of the head, neck and upper extremities. The authors describe the case of a 76-year-old female patient presenting an anterior cervical mass, measuring 2×2 cm, which was mobile, tender and slightly painful with no alteration of the overlying skin. Complementary study with ultrasound and computed tomography was inconclusive. Total excision of the lesion was performed with histology compatible with intravascular papillary endothelial hyperplasia.

Some of the patients with anaplastic thyroid carcinomas have a coexistent differentiated thyroid cancer, sustaining the hypothesis that this cancer may develop from more differentiated tumors. We describe a case with a collision tumor of the thyroid, defined as a neoplastic lesion composed of two distinct cell populations, with distinct borders. The patient presented during the COVID-19 pandemic with dysphonia, dyspnea, multinodular goiter and a painless, rapidly enlarging, left cervical swelling. She had been first time diagnosed with left nodular goiter in 2007, with an indication for surgery, which she declined. After partial excision of the left latero-cervical adenopathy, the pathological analysis showed massive lymph node metastasis from anaplastic thyroid cancer. A total thyroidectomy was done; the postoperative pathological exam identified a papillary thyroid microcarcinoma in the right lobe and an anaplastic thyroid cancer in the left lobe. Postoperatively, levothyroxine treatment was started and the patient was referred to radiotherapy. This case highlights the importance of urgent management of some cases with compressive multinodular goiter, even during the COVID-19 pandemic.

Ovarian pathology ranges from innocuous non-neoplastic lesions to malignant neoplastic entities. The incidence, clinical appearance and the behaviour of the different types of ovarian tumour is extremely variable. In order to have a better understanding of frequency and histomorphological patterns of different ovarian lesions study was encountered in our tertiary care hospital.To study the histopathology of ovarian non-neoplastic and neoplastic lesions and to study the distribution of ovarian lesions with respect to various parameters like age, bilaterality, gross and microscopic features.This is a prospective study of 125 ovarian specimens received in department of pathology, G.K. General Hospital, Bhuj during August 1, 2018 to July 31, 2020. Total 125 cases of ovarian specimens were studied, amongst them 58 were non-neoplastic and remaining 67 were neoplastic. The most common non-neoplastic lesion seen was follicular cysts 12 cases (21%), followed by endometriosis 9 cases (16%). Among 67 neoplastic ovarian lesions 58(87%) cases were benign, 3(4%) cases were borderline and 6 (9%) cases were malignant. In benign ovarian neoplasm, most commonly seen lesions were serous cystadenoma 24 cases (36%) followed by 13 cases (20%) of mature cystic teratoma. In malignant cases, maximum was of high-grade serous cystadenocarcinoma.Ovarian epithelial tumours are the most common type, while serous cystadenocarcinoma was the most common malignancy. Histological examination is gold standard and in certain difficult cases require immunohistochemistry.Ovary is an important reproductive organ with involvement in production of progeny.Ovarian pathology ranges from innocuous non-neoplastic lesions to malignant neoplastic entities. Ovarian neoplasms have become increasingly important not only because of the wide range of neoplasms, but also because they have gradually increased the mortality rate. The incidence, clinical appearance and the behaviour of the different types of ovarian tumour is extremely variable.

Hypophysitis is a rare inflammatory condition that may present both clinically and radiologically as a neoplastic lesion. Xanthogranulomas are rare intracranial lesions with controversial etiology. Here, we report a clinical case of histologically confirmed xanthogranuloma in a young female with type I diabetes mellitus and hypothyroidism.
