Background: Ductal carcinoma in situ (DCIS) is a non-invasive breast cancer with varying potential for progression to invasive carcinoma. Myoepithelial cells (MECs) play a role in preventing this progression, and their absence is a hallmark of invasive disease. The p63 protein is a myoepithelial marker that can be assessed by immunohistochemistry (IHC). This study aimed to evaluate the relationship between p63 expression in MECs, the grade of DCIS, and the morphological subtype of DCIS. Methods: A cross-sectional study was conducted on 35 cases of DCIS diagnosed at the Anatomical Pathology Laboratory of Dr. M. Djamil General Hospital Padang. Paraffin blocks were collected, and Hematoxylin and Eosin (H&E) slides were reviewed to confirm the diagnosis and determine the histopathological grading (low, intermediate, and high) and morphological variants (comedo and non-comedo) of DCIS. Paraffin blocks were re-cut for p63 immunohistochemical staining. The extent of p63 expression was classified as complete or incomplete. Results: The majority of DCIS cases were high grade (54.3%) and of the non-comedo subtype (68.4%). All cases with complete p63 expression were of low histologic grade, while all cases with incomplete p63 expression were of high histologic grade. The results of the Chi-square test showed a statistically significant relationship between p63 expression and histopathological grading (p<0.001). There was no statistically significant relationship between p63 expression and morphological variant. Conclusion: The absence of p63 expression in DCIS is associated with high histologic grade. This finding suggests that p63 IHC may be a useful adjunct in evaluating DCIS.

Background: Colorectal cancer (CRC) is a major health burden globally. The prognosis of CRC is strongly influenced by the presence of lymphovascular invasion (LVI) and lymph node (LN) metastasis. Transforming growth factor-beta (TGF-β) is a cytokine with a complex role in CRC progression. This study aimed to evaluate the significance of TGF-β expression in predicting LVI and LN metastasis in CRC. Methods: This cross-sectional study involved 50 patients diagnosed with CRC. The expression of TGF-β was assessed using immunohistochemical staining and the Allred scoring system. The relationship between TGF-β expression and the presence of LVI and LN metastasis was analyzed using the Chi-square test. Results: High TGF-β expression was significantly associated with both LVI (p = 0.011) and LN metastasis (p = 0.012) in CRC. Patients with high TGF-β expression had a higher risk of LVI and LN metastasis compared to those with low TGF-β expression. Conclusion: TGF-β expression is a significant predictor of LVI and LN metastasis in CRC. This finding has potential implications for risk stratification and treatment decisions in CRC patients.

Background: Primary malignant peritoneal mesothelioma (PMPM) is an uncommon and aggressive malignancy arising from the mesothelial lining of the peritoneal cavity. The diagnosis of PMPM is often challenging due to its rarity, nonspecific clinical presentation, and histologic similarities to other malignancies, particularly adenocarcinomas. Immunohistochemistry plays a crucial role in differentiating PMPM from metastatic adenocarcinoma, which is essential for accurate diagnosis, appropriate treatment, and prognostication. Case presentation: We present the case of a 43-year-old female who presented with abdominal distension, ascites, and weight loss, initially raising suspicion of ovarian carcinoma. However, histopathological examination of the omental tissue revealed a proliferation of epithelial cells with papillary and glandular-like growth patterns. Immunohistochemical staining demonstrated strong positivity for calretinin, a mesothelial marker, while staining for estrogen receptor (ER) and progesterone receptor (PR) was negative, effectively ruling out an ovarian or endometrial origin. The diagnosis of PMPM, epithelioid subtype, was confirmed. Conclusion: This case underscores the challenges in diagnosing PMPM and highlights the critical role of immunohistochemistry in differentiating it from metastatic adenocarcinoma. Accurate diagnosis is essential for determining appropriate management strategies and providing prognostic information.

Background: Papillary thyroid carcinoma (PTC) is generally indolent, yet specific histological subtypes defined by the World Health Organization (WHO) are linked to aggressive behavior and poor prognosis. The loss of the cell-adhesion protein E-cadherin is a hallmark of the epithelial-to-mesenchymal transition (EMT), a process implicated in tumor aggression. However, its role in stratifying PTC subtypes versus its correlation with tumor stage remains a significant controversy in the literature. This study aimed to disentangle these two parameters by clarifying the relationship between E-cadherin expression and both histological phenotype and tumor stage. Methods: This was an observational, cross-sectional pilot study on 40 randomly selected, formalin-fixed, paraffin-embedded (FFPE) PTC cases from a 2024 cohort (N=74) at a tertiary hospital in Indonesia. All cases were re-evaluated and classified according to the WHO 5th Edition (2022) criteria as non-aggressive (n=34) or aggressive (n=6). E-cadherin expression was assessed by immunohistochemistry (IHC) using a standardized semi-quantitative scoring system (product of intensity and proportion) adapted from previous studies, with inter-rater reliability assessed (Cohen’s Kappa = 0.88). Scores were dichotomized as 'High' (n=25) or 'Low' (n=15). The association between E-cadherin expression and both histological subtype and AJCC 8th Edition tumor stage (Early: I/II [n=32] vs. Advanced: III/IV [n=8]) was analyzed using Fisher's Exact Test, with Odds Ratios (OR) and 95% Confidence Intervals (CI) calculated. Results: High E-cadherin expression was observed in 62.5% of cases. A statistically significant and strong association was found between E-cadherin expression and histological subtype (p=0.021; OR 12.0; 95% CI 1.2–118.9). Low E-cadherin expression was present in 83.3% (5 of 6) of aggressive-subtype tumors, versus only 29.4% (10 of 34) of non-aggressive subtypes. In contrast, no significant correlation was found between E-cadherin expression and advanced tumor stage (p=0.126; OR 3.67; 95% CI 0.7–18.6). Conclusion: Loss of E-cadherin expression is a significant biomarker associated with high-risk, aggressive histological phenotypes in PTC. Its lack of correlation with tumor stage, confirmed by an uncertain OR, suggests E-cadherin's role is indicative of an inherent tumor biological phenotype (aggressiveness) rather than a linear marker of tumor progression (stage). This dichotomy, likely reflecting EMT/MET plasticity, positions E-cadherin IHC as a powerful ancillary tool for pathological risk stratification.

Background: Partial thickness wounds refer to the damage that extends from the epidermis to the upper layers of dermis. This study aims to compare the histological regrowth of acute partial thickness wounds following application of lyophilized amniotic membrane, tulle grass dressing and topical gentamicin. This study aims to establish a standard approach for treating partial thickness wound. Methods: Three groups of Mus Musculus mice were used in our experimental study. Similar to harvesting split thickness skin grafts, partial thickness wounds are performed. The wound was then treated with lyophilized amniotic membrane, tulle grass dressing and topical gentamicin. Using the Scoring System for Histological Assessment of Wound Healing, the wound is histopathologically examined at day 14. In this study, One way Anova was used for statistical analysis. Results: Application of lyophilized amniotic membrane showed different histological characteristic of healing from other method, with p=0.001 it showed significance epidermal growth compared to topical gentamicin. Whereas dermal thickness were also better, accompanied by lower dermal collagen density. Amniotic membrane has a large source of stem cells and contains several growth factors which is important in the physiological process of wound healing and tissue regeneration. Conclusions: Characteristic of skin healing using lyophilized amniotic membrane showed rapid epidermal growth and gave impression of less fibrosis tissue, so that would be potential for better wound treatment especially for prevention of scar.

Background: Hyperglycemic is a condition characterized by elevated blood glucose levels, with serum blood glucose levels exceeding 126 mg/dL. Hyperglycemia can induce oxidative stress. Oxidative stress occurs due to an increase in free radicals or a decrease in antioxidant defense activity. Cinnamon bark can enhance antioxidant levels and decrease indicators of oxidative stress. This study examines the impact of cinnamon bark extract on catalase activity levels in hyperglycemic rats. Method: This study used an experimental design with a post-test-only group design. The rats were divided into 5 groups, namely the negative control group (K-), the positive control group (K+), treatment group 1 (dose 100 mg/kgBW), treatment group 2 (dose 200 mg/kgBW) and treatment group 3 (dose 300 mg/kgBW) with 6 rats each. The normality test was carried out using the Shapiro-Wilk test followed by One Way ANOVA. Result: The administration of cinnamon bark extract has been shown to increase catalase activity levels. The most significant increase was observed in dose group 1, with an average of 5.62 Units/mg, which is higher than the control group + (K+), at 3.88 Units/mg. Conclusion: Administration of bark extract has been shown to increase catalase activity in hyperglycemic Rats.

Background Meningiomas are the most common primary tumors of the central nervous system. About one-fifth of meningiomas tend to recur. The World Health Organization (WHO) histopathological grade was the most useful morphological predictor of recurrence. Fibrotic tumor vessels (FTV) were detected in nearly half of WHO grade I meningiomas and correlated with vascular density and increased risk of recurrence. Fibulin-2 is an extracellular matrix glycoprotein whose expression increases in traumatic central nervous system injuries and can be used as a marker to differentiate the histopathological grade of meningiomas. This study aimed to determine the association of fibulin-2 expression with histopathological grade and FTV in meningiomas. Methods This research was an observational cross-sectional study. The study sample was 36 cases of meningioma in three Anatomical Pathology laboratories in West Sumatra on period January 2019 to December 2020. Samples obtained from resected meningioma cases were then reevaluated on Hematoxylin Eosin (HE) slides to determine the histopathological grade and FTV. Van-Gieson staining was performed to confirm FTV. Fibulin-2 expression in tumor cells was analyzed using immunohistochemical staining. Bivariate statistical analysis using the Chi-Square test with p<0.05 was considered significant. Result High-risk meningiomas (WHO grade II and III) showed high fibulin-2 expression (62.5%), whereas low-risk meningiomas (WHO grade I) were more abundant with low fibulin-2 expression (75%). The presence of FTV at low fibulin-2 expression was 58.3%. Statistical analysis showed no significant association between fibulin-2 expression with histopathological grade (p=0.077) and FTV (p=1,000). Conclusion In summary, the study showed that fibulin-2 expression was not associated to histopathological grade nor to FTV in meningiomas.

Background: Uterine smooth muscle tumor of uncertain malignant potential (STUMP) presents a diagnostic dilemma, especially in Southeast Asian populations, where delayed presentation often leads to advanced tumor burden. This study aimed to characterize the clinicopathological profile of STUMP in Indonesia using the 2021 WHO Classification and modified Stanford parameters. Methods: A descriptive study analyzed 37 STUMP cases diagnosed between 2023 and 2025 at a tertiary referral center in West Sumatra. A panel of pathologists re-evaluated archival slides for atypia, mitotic activity, necrosis, and growth patterns, establishing inter-observer reliability. Fisher’s Exact Test was employed to correlate tumor size with morphological markers of aggression. Results: The cohort demonstrated a distinct large-mass phenotype, with 54.1% of tumors exceeding 10 cm and a median diameter of 14.5 cm. Pathological review classified 56.8% of cases into WHO Group 4 (atypia with ambiguous mitosis). A statistically significant correlation was identified between tumor size >10 cm and the presence of infiltrative growth margins (81.1%; p=0.034). Conclusion: Indonesian STUMP cases are distinctively characterized by massive size and high rates of infiltrative growth, likely driven by prolonged natural history. The prevalence of ambiguous mitotic figures underscores the utility of the WHO Group 4 category in resource-limited settings. These findings advocate for aggressive surgical management and wider resection margins in large-mass variants to mitigate local recurrence risk.
