Leiomyosarcoma (LMS) represents an aggressive neoplasm that often involves a diagnostic challenge when encountered in atypical anatomical sites. The case here exposed involves a 70-year-old female with a retroperitoneal mass measuring 65 mm × 65 mm, likely of adrenal origin, warranting consideration for adrenalectomy. Histopathological examination reveals spindle cells arranged in intersecting fascicles, displaying pleomorphism and necrosis, and is immunohistochemically positive for actin and desmin markers. The definitive diagnosis is LMS, demonstrating venous origin without infiltration of the adrenal gland. Regrettably, the patient succumbed to post-operative complications. The inconspicuous nature of LMS in this anatomical niche complicates preclinical detection, underscoring the pivotal role of histopathological analysis in its identification. Furthermore, achieving complete excision proves challenging, resulting in a poorer prognosis compared to conventional LMS, despite the availability of alternative treatment modalities. Given the absence of standardized management protocols, a multidisciplinary approach remains essential.

Background
Sarcoidosis, a granulomatous inflammatory disease, exhibits diverse clinical manifestations, often affecting multiple organs. Diagnostic challenges arise due to its similarities with tuberculosis, particularly in high-burden areas. Differentiating between the two relies on clinical judgment, laboratory tests, imaging, and invasive procedures. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has emerged as a valuable diagnostic tool, enhancing both accuracy and patient care.
Material and methods
This study enrolled 279 suspected sarcoidosis cases, evaluated via EBUS-TBNA between November 2022 and August 2023. The inclusion criteria comprised intrathoracic lymphadenopathy on CT, with subsequent diagnoses of either sarcoidosis or tuberculosis. Clinical, radiological, and laboratory assessments, along with EBUS-TBNA, were conducted. Cytopathological analysis focused on the presence of granulomas, histiocytic clusters, lymphocyte depletion, and necrosis, which aided in diagnosis. Statistical analysis was conducted using SPSS software to evaluate sensitivity, specificity, and predictive values.
Results
Out of 279 patients, 178 were diagnosed with sarcoidosis and 90 with tuberculosis. Adequate TBNA samples were obtained in 240 cases, predominantly from male patients. Negative tuberculin skin tests and negative culture studies were significant findings in the sarcoidosis cases (p < 0.0001). Echotexture and necrosis were distinguishing features of tuberculosis, while granulomas and histiocyte patterns varied. The sensitivity and specificity for diagnosing sarcoidosis via cytomorphology were notable, particularly when combined with negative microbiological findings.
Conclusion
Cytomorphological analysis via EBUS-TBNA significantly aids in the diagnosis of sarcoidosis, despite overlapping features with tuberculosis. The absence of necrosis and distinctive granuloma characteristics contribute to its high sensitivity and specificity. Radiological correlations and microbiological findings further enhance diagnostic accuracy. This study underscores the importance of comprehensive evaluation in intrathoracic lymphadenopathies, highlighting the pivotal role of EBUS-TBNA in tuberculosis-endemic regions.

Introduction
The analysis of histological images plays a fundamental role in studying pathological alterations associated with human diseases, especially in the context of practical teaching. However, in the Biology Degree programme there is a lack of practical activities based on the study of human histological preparations.
Material and methods
A collaboration with an Anatomical Pathology department was established for this project, which aimed to carry out an innovative practice based on the study of human biopsies in the subject of Cell Biology and Cellular Pathology of the Biology Degree programme. Face-to-face and non-face-to-face activities were performed, involving group work, image search and selection for the preparation of digital material.
Results
This activity allowed for the identification of morphological changes caused by the deregulation of cellular processes in various diseases.
Conclusions
Our results indicate that students find this practice very useful for their training, so this activity could be applied to other similar subjects taught in other degree programmes.
