Background/Objectives: Metatypical basal cell carcinoma (MTBCC) is a rare and aggressive variant of non-melanoma skin cancer (NMSC) characterised by overlapping histological features of basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC). Owing to its increased propensity for local invasion, recurrence, and metastasis, MTBCC poses diagnostic and therapeutic challenges. This study aimed to characterise the epidemiological, histopathological, and clinical features of MTBCC and to evaluate temporal changes in tumour characteristics and aggressiveness before, during, and after the COVID-19 pandemic. Methods: A retrospective cohort study was conducted on 129 histologically confirmed MTBCC lesions diagnosed in the Pathology Department of the Mures Clinical County Hospital, Targu Mures, Romania, between January 2017 and December 2025. Demographic data, tumour location, histological subtypes, differentiation of the squamous component, aggressiveness parameters, and volumetric measurements of tumours and excision specimens were analysed. Volumetric analyses were restricted to cases with complete three-dimensional measurements. Statistical comparisons were performed across demographic variables and the following three time periods: pre-pandemic, pandemic, and post-pandemic. Results: The median age at diagnosis was 71 years, with a slight male predominance (p = 0.25) and a significant predominance of patients from urban areas (p < 0.001). Most tumours were located in the head and neck region. Mixed-type MTBCC was significantly associated with higher tumour aggressiveness (p = 0.0019) and with high-risk histological subtypes, particularly micronodular and adenoid–cystic variants. Tumour volume showed a significant inverse correlation with year of diagnosis (p = 0.0139; r = (−) 0.50), whereas excision specimen volume differed significantly according to year of diagnosis (p = 0.0425). Neither tumour volume nor excision specimen volume was associated with histopathological aggressiveness. Conclusions: Metatypical basal cell carcinoma is a rare skin malignancy in which biological behaviour appears to be determined primarily by histopathological architecture rather than tumour size. Mixed-type lesions were associated with significantly higher aggressiveness, underscoring the need for accurate histopathological assessment. These findings support a pathology-driven approach to management and emphasise the importance of adequate surgical treatment and long-term follow-up in patients with MTBCC.

Background/Objectives: Empathy is a fundamental component of patient-centered care and plays a critical role in the physician–patient relationship. This study aimed to evaluate empathy levels among undergraduate medical students at a medical university in Romania, examined from a Medical Humanities perspective, and to analyze how these scores are distributed according to gender, academic year, clinical stage, and direct experience with patient contact. Methods: A descriptive, cross-sectional study was conducted among 209 undergraduate medical students across all six academic years. Empathy levels were assessed using the Romanian-language version of the Jefferson Scale of Empathy—Student Version (JSE-S). Differences in empathy scores were analyzed using independent samples t-tests and a one-way analysis of variance (ANOVA) with Tukey Honestly Significant Difference (HSD) post hoc comparisons. Statistical significance was set at an alpha level of less than 0.05. Results: Internal consistency of the JSE-S total scale was good (Cronbach’s α = 0.829). The overall mean total JSE-S score was 107.34 ± 14.34. Female students demonstrated significantly higher empathy scores compared to male students (109.92 ± 13.10 versus 99.37 ± 15.20; t = 4.450; p < 0.001; Cohen’s d = 0.77). No statistically significant differences were found between preclinical and clinical stage students (106.84 ± 14.75 versus 108.98 ± 12.90; p = 0.363; Cohen’s d = −0.15), between students with and without direct patient contact (108.20 ± 14.14 versus 104.48 ± 14.78; p = 0.115; Cohen’s d = 0.26), or across the six academic years (F = 1.614; p = 0.158; partial η2 = 0.038). Conclusions: Medical students demonstrated moderate-to-high empathy levels, with gender representing the only statistically significant demographic factor. The absence of major differences across academic-year cohorts and clinical exposure suggests that empathy levels were comparably represented across the different stages of training within this cross-sectional sample. These findings contribute descriptive data on empathy levels among Romanian medical students and highlight gender as the main factor associated with variation in empathy scores in this sample.

Background and Objectives: Spitz tumors represent a diagnostic challenge in dermatopathology due to their large spectrum of morphological characteristics and overlap with malignant lesions, especially in pathology departments where molecular pathology is not available. Even though most Spitz lesions are benign, the uncertainty around their biological behavior necessitates an integrated approach in daily practice. The objective of our study was to evaluate the epidemiological, macroscopic, and histopathological characteristics of Spitz lesions in accordance with WHO Classification of Skin Tumours. Materials and Methods: We performed a retrospective, descriptive, and hypothesis-generating study on Spitz tumors diagnosed between 2018 and 2024 in the Clinical Pathology Department of the Mures Clinical County Hospital, Romania. We included 10 cases and analyzed their macroscopic characteristics (localization, shape, dimension, and color), microscopic characteristics (cellular types, cytologic atypia, pagetoid migration, mitoses, and the type of lesion), and immunohistochemical profile. Results: The study population was composed of young patients with an average age of 20.2 years old, with a slight predominance of female gender. Most lesions were Spitz nevi, intradermic, or compound, with a fusiform, epithelioid, or rhomboid cell shape. Pagetoid migration and cytological atypia were seen in fewer cases. The Ki 67 proliferation index was under 5% in all cases. The main limitation of this study involved the low number of cases and the lack of molecular testing, which limited the molecular characterization of Spitz tumors. Complete excision was performed in all cases. Conclusions: In the absence of molecular testing, our study emphasizes the importance of clinical–morphological assessment using immunohistochemistry in establishing a correct diagnosis in Spitz lesions. Our results confirm that most of the Spitz lesions were benign and provide a basis for future research with a multidisciplinary approach, including molecular testing.
