Background Contrast-enhanced spectral mammography (CESM) may help to determine the malignancy potential of lesions according to the degree of enhancement. Purpose To investigate the correlation between the degree of contrast enhancement of the lesions in contrast-enhanced spectral mammography (CESM) and the final histopathological diagnosis in patients with BI-RADS 4 and 5 lesions. Material and Methods CESM was performed in 128 patients who had BI-RADS 4 and 5 lesions on mammography and underwent histopathological examination. A total of 128 index lesions were scored using a 4-point scale regarding the degree of contrast enhancement (0 = no contrast enhancement, 1 = minimal, 2 = moderate, 3 = marked), a score of 2 and 3 was accepted as suggestive of malignancy. The study was approved in our institutional scientific committee. Results In total, 76 (59.4%) of the lesions had benign histopathological results, whereas 52 of them had malignant results. Contrast enhancement was not observed in 22.7% of the lesions while 24.2% had minimal enhancement, 18.8% had moderate enhancement, and 34.4% had marked enhancement in CESM. The sensitivity of the degree of contrast enhancement in CESM was 98.1%, when the specificity was 77.6%, positive predictive value was 75%, negative predictive value was 98.3%, and accuracy was 85.9%. Conclusion This study demonstrated that the degree of contrast enhancement of the lesions in CESM may be used in daily practice with easily performing a visual scale in predicting the malignancy potential of the lesions.

Rapid and accurate histopathological diagnosis during surgery is critical for clinical decision-making. The prevalent method of intraoperative consultation pathology is time, labour and cost intensive and requires the expertise of trained pathologists. Here, we present an alternative technique for the rapid, label-free analysis of biopsy samples by sequentially assessing the physical phenotype of singularized, suspended cells in high-throughput. This new diagnostic pipeline combines enzyme-free, mechanical dissociation of tissues with real-time deformability cytometry at measurement rates of 100 - 1,000 cells/sec, and machine learning-based analysis. We show that physical phenotype parameters extracted from brightfield images of single cells can be used to distinguish subpopulations of cells in various tissues, without prior knowledge or the need for molecular markers. Further, we demonstrate the potential of our method for inflammatory bowel disease diagnostics. Using unsupervised dimensionality reduction and logistic regression, we accurately differentiate between healthy and tumorous tissue in both mouse and human biopsy samples. The method delivers results within 30 minutes, laying the groundwork for a fast and marker-free diagnostic pipeline to detect pathological changes in solid biopsies.

Background: Cervical cancer is the most common genital cancer in India. In India alone,almost,130000 new cases occur with the death toll of 70000 everywhere. Objective of current study was correlation of pap smear with histopathological diagnosis.Methods: A retrospective study was conducted in tertiary care hospital in 130 sexually active women. Pap smears were taken and histopathological diagnosis was performed in all such patientsResults: From pap smear findings, out of 130 patients, maximum number of cases, 74 (56.9%) were categorized as. Out of epithelial cell abnormality, ASCUS was seen in 25 patients (10.2%), LSIL in 17 patients (13.1%), HSIL in 11 patients (8.5%). SCC was seen in 2 patients (1.5%) and adenocarcinoma in 1 patient (0.8%). From cervical biopsy reports, 51 cases(39.2%) were diagnosed as chronic cervicitis, 34 cases (26.2%) were diagnosed as chronic cervicitis with squamous metaplasia, CIN I in 31 patients (23.8%), CIN II in 8 patients (6.2%) and CIN III in 3 patients (2.3%), squamous cell carcinoma in 2 patients (1.5%) and adenocarcinoma in 1 patient (0.8%). The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of pap smear test was 91.1%, 82.4%,73.2%, 94.6% and 85.4%, respectively.Conclusions: Pap smear has excellent correlation with histopathological diagnosis. Therefore it should be encouraged as effective tool for cervical cancer screening program to reduce incidence and mortality caused by cervical cancer.

We earlier reported that cell-projection pumping transfers fibroblast contents to cancer cells, and this alters cancer cell phenotype. We now report on single-cell tracking of time lapse recordings from co-cultured fluorescent fibroblasts and SAOS-2 osteosarcoma cells, tracking 5,201 cells across 7 experiments. The fluorescent lipophilic marker DiD was used to label fibroblast organelles, and to trace transfer of fibroblast cytoplasm into SAOS-2. We related SAOS-2 phenotypic change to levels of fluorescence transfer from fibroblasts to SAOS-2, and also to what we term 'compensated fluorescence', that numerically projects mother cell fluorescence post-mitosis, into daughter cells. Comparison of absolute with compensated fluorescence, allowed deduction if phenotypic effects in mother SAOS-2, were inherited by their daughters. SAOS-2 receipt of fibroblast fluorescence correlated by Kendall's tau: with cell-profile area, and without evidence for persistence in daughter cells (median tau = 0.51, p < 0. 016); negatively and weakly with cell circularity, and with evidence for persistence (median tau = -0.19, p < 0.05); and very weakly with cell migration velocity, and without evidence for persistence (median tau = 0.01, p < 0.016). Also, mitotic SAOS-2 had higher rates of prior fluorescence uptake (median = 64.9 units/day), compared with non dividing cells (median = 35.6 units/day, p < 0.016), and there was no evidence for persistence post-mitosis. We conclude there is appreciable impact of cell-projection pumping on cancer cell phenotype, relevant to cancer histopathological diagnosis, clinical spread, and growth, with most effects 'reset' by cancer cell mitosis.

Abdominal wall endometrioma (AWE) is one of the rarest forms of the endometriosis, and usually found in the young patients, average age is 35years. The most common triad of the symptoms is, abdominal mass at or near the scar, cyclical pain and history of previous caesarean or any other gynecological surgery. Exact pathogenesis is unknown as average time of its presentation in the patients is highly variable from 3 months till 2 decades. It can be suspected on ultrasonography and CT scan and MRI are the modalities used to assess and stage the lesion prior to the surgery. Histopathological diagnosis is confirmatory. We are reporting 30 years old, Para 2, with history of first caesarean section 6 years ago followed by the normal delivery. She presented with the history of cyclical abdominal pain with the feeling of abdominal lump from last 3 months. On examination a slightly tender 5*4 cm extra abdominal mass was palpable above the right half of the previous transverse scar of the caesarean. After evaluation endometriosis was suspected and the patient opted for the surgical resection of the mass. The mass was removed in collaboration with the surgeons and the histopathology confirmed the diagnosis of the AWE. Conclusion: AWE is a dynamic yet incompletely known entity as a result of increasing number of the caesarean and gynecological procedures. It should be kept in the differential diagnosis of the patients coming with the cyclical abdominal pain and abdominal lump with the history of previous uterine surgery. Ultrasound and MRI are the main aiding modalities but the confirmation of the diagnosis is made only after histopathology. The surgical removal of the mass with negative margins represents the current best treatment. Key words: Abdominal wall, endometriosis, magnetic resonance imaging, ultrasonography.

Background: Oral lichen planus (OLP) is considered an oral potentially malignant disorder. The aim of our study was to estimate the risk for oral cancer in patients diagnosed with OLP. Methods: A population-based cohort study between January 1988 and December 2020 at one hospital in Northern Italy was performed. The primary endpoint of the study was that of the histopathological diagnosis of oral cancer during the follow-up period. Results: The study population comprised 3173 patients. During the follow-up period, 32 men and 50 women developed an oral squamous cell carcinoma (2.58%), with a mean time of 103.61 months after the initial diagnosis of OLP, and 21 patients died because of oral cancer. Almost half of the deceased patients had the last follow-up visit before cancer diagnosis in a period of more than 12 months. Older age, having a red form of OLP and fewer sites of involvement, increased the risk of having cancer, while age and no treatment increased the risk of death. Conclusion: This is the largest group of OLP patients with such a long follow up ever reported. Due to the increased risk of having a malignant transformation, especially in elderly subjects, OLP patients should be regularly followed up, particularly in the Northern Italian population.

Pleomorphic lipoma is a rare neoplasm that is considered as a variant of spindle cell lipoma. It predominantly occurs in the dermis or subcutis of the posterior neck, upper back, and shoulders. Pleomorphic lipoma may clinically present as a slow-growing and well-circumscribed subcutaneous mass. Though it is a benign tumour it may contain atypical cells for which it may mimick sarcoma or other malignant soft tissue tumours. So histopathological diagnosis is vital for preventing unnecessary surgery. Here we report a case of a pleomorphic lipoma on upper back in a 55yr old patient.

Acute appendicitis is sudden inflammation of the appendix, usually initiated by obstruction of the lumen. This results in invasion of the appendix wall by gut flora, and it becomes inflamed and infected.: To investigate retrospectivelythe prevalence and implications of unusual histopathological findings in appendectomy specimens from patients with suspected acute appendicitis.This is retrospective assessment of hospital records of 150 patients who were diagnosed as acute appendicitis and underwent appendicectomy during March 2018 to February 2020 at Government Medical College, Bhagya Nagar, Ongole, Andhra Pradesh .Data of the patients were assessed based on age, sex, histopathological diagnosis, coexisting pathologies and uncommon findings on histology. According to histopathology report, negative for acute appendicitis were noted in 82 cases (55%), whereas positive for acute appendicitis in 68 cases (45.3%) . Rare findings were foundin 38 (55.8%) cases out of 68 cases. Parasites were found in 7 (18.4%) (Enterobius Vermicularis, Balantidum Coli, Schistosoma Haematobium), Mucocele in 12 (32%), carcinoid tumour in 8(21%), B cell malignant lymphoma in 2 (5%), leiomyoma in 2 (5%), Primary appendiceal adenocarcinoma in 3 (8%), Acute appendicitis with dysplastic changes in 2 (5%) and inflammatory bowel polyp was reported in remaining two cases(5%).: Even though unusualpathologies can be seen rarely during appendectomy, this should be kept in mind for further evaluation of each cases.

Abstract Paraganglioma (PGL) is a rare tumor originating from extra-adrenal paraganglionic chromaffin tissues, and most sympathetic PGLs have excessive catecholamine secretion. However, non-functional PGLs are sometimes found. Although malignant PGL is defined by metastasis to non-chromaffin tissues, it is difficult to predict malignancies due to the lack of reliable markers of potential malignancies. We report the case of a 69-year-old Japanese woman with an incidental retroperitoneal tumor and multiple enlarged mesenteric lymph nodes simultaneously. There were no subjective symptoms of the patient and no laboratory findings suggesting catecholamine hypersecretion. Both the retroperitoneal tumor and the enlarged mesenteric lymph nodes showed high accumulation of fluorodeoxyglucose (FDG), whereas metaiodobenzylguanidine (MIBG) was accumulated only at the retroperitoneal tumor. Although a retroperitoneal tumor was diagnosed as non-functional PGL by examination including MIBG scintigraphy, the cause of enlarged mesenteric lymph nodes could not be diagnosed by imaging and biochemical tests. As a result of retroperitoneal tumor resection and mesenteric lymph nodes sampling, histopathological examination revealed that a retroperitoneal tumor was PGL and enlarged mesenteric lymph nodes were follicular lymphoma. To reveal an underlying genetic factor, we performed whole exome sequencing of genomic DNA, and we identified two possible candidate variants in SDHD and DLST, but the pathogenicity of these variants remains uncertain in the present case. This rare case reinforces the importance of histopathological diagnosis of non-chromaffin tissue lesions in patients with PGL for the appropriate treatment strategy.
