Abstract	Introduction: Despite the established role of the interventional pathologist, their diagnostic performance is difficult to establish. At least in Spain training of pathology residents in ultrasound-guided interventional procedures for specimen collection is limited or absent in most institutions. We present our teaching experience in the instruction of ultrasound-guided fine-needle aspiration (FNA) to pathology residents in a tertiary-level hospital. Materials and methods: The training of pathology residents who rotated through the interventional unit of the pathology department and the application of ultrasound-guided FNA and rapid on-site evaluation (U-ROSE) was documented over 5 years. The training period was broken down into learning phases and included the number of ultrasound-guided FNA performed, anatomical location, and their diagnostic performance, among other aspects. Results: Nineteen (19) pathology residents were trained in U-ROSE, and performed a total of 4003 procedures, with a mean of 211 per resident. In 53% of cases only one pass was required for an adequated sample. The specimen was diagnostic in more than 97% of cases. The most frequently sampled anatomical sites were the thyroid gland (n = 2347), followed by lymph node (n = 667), soft tissues (n = 663) and salivary glands (n = 322). Conclusion: The results support the training programme followed by pathology residents in learning U-ROSE, which is essential to lay the foundations for the future interventional pathologist.

Title translation	Lung clear cell tumor «sugar tumor». Unusual diagnostic neoplasm.
Abstract	Clear Cell «sugar tumor» of the lung is a rare nosological entity of which around 60 cases have been published in the scientific literature. Considered to be of mesenchymal origin, it presents a typical histochemical - immunohistochemical profile, positive PAS and melanic markers, which allows it to be differentiated from other more frequent neoplasms with worse prognosis. We present the case of a 56-year-old man with a clear cell lung tumor. Radiological, macro-microscopic and histochemistry - immunohistochemical characterization, as well as a brief review of the literature.

Abstract	Sclerosing Mesenteritis (SM) is a rare diagnosis, particularly in pediatric patients, and is typically non-fatal when appropriately treated. Although molecular and immunohistochemical alterations have been described, no pathognomonic signature has been identified for this entity. This report presents a case of a seven-year-old boy who suffered sudden cardiorespiratory arrest. Upon autopsy, he was found to have multicentric SM on the upper mesentery, which led to bowel wall thinning and abdominal bleeding with bacterial translocation. We performed comprehensive morphological, immunohistochemical, and molecular analyses. SM is an atypical disorder with diverse clinical manifestations, including a rare but potentially fatal course. Early diagnosis is critical, given its potential severity. To our knowledge, this is the first case report of pediatric mortality linked to SM. Our findings emphasize the importance of increased awareness and early detection of SM in pediatric patients.

Title translation	Unusual presentation of metastasis of prostate carcinoma as a mediastinal mass: A case report and a brief review of the literature.
Abstract	Objective: To assess the metastasic prostatecancer in the differenctial diagnosis of mediastinal masses. METHODS: To report a case. RESULTS: We present the case of a 78-year-old male patientwith a diagnosis of prostate cancer with a mediastinalmass compatible with prostate metastasis. CONCLUSION: Mediastinum is a very rare site for prostatecancer metastasis, but it must be considered in thedifferential diagnosis of mediastinal masses. Treatment isthe usual for metastatic prostate cancer.

Abstract	Signet-ring cells are morphologically defined by the presence of a large intracytoplasmic vacuole that compresses and displaces the nucleus to the periphery. In most cases, these cells are associated with adenocarcinomas of various locations, and with non-epithelial neoplasms. To date, less than 20 cases of squamous cell carcinoma with signet-ring morphology have been described, mainly located on the skin. We present the case of a 73-year-old male with pleural effusion and a left lower lobe mass. The cytological study of the pleural effusion allowed the diagnosis of metastasis of squamous cell carcinoma, signet-ring cell variant. The treatment of lung cancer in advanced stages requires a precise diagnosis that allows the best therapy to be offered to the patient, depending on the clinical stage and the positivity of the biomarkers, among others. Our patient died 18 months after the initial diagnosis.

Abstract	Amyloid goiter (AG) (primary or secondary) is extremely rare. An abdominal fat pad core needle biopsy (CNB) is the diagnostic gold standard for secondary amyloidosis. Although CNB is useful to detect amyloid infiltration of a specific organ, fine-needle aspiration (FNA) is proven to be the best diagnostic method for thyroid disorders. Guidelines recommend an ultrasound-guided FNA (US-FNA) whenever possible. This procedure is usually performed by various interventional specialists, including pathologists, who perform the procedure in addition to validating the adequacy of the sample. We report a rare case of AG diagnosed using US-FNA performed by a pathologist in a 39-year-old patient with systemic amyloidosis. US-FNA performed by pathologists is a proven, less-invasive, and cost-effective tool that ensures acquisition of adequate specimens and reduces nondiagnostic rates of this procedure to ensure timely cytological diagnosis.

Title translation	Minimally invasive percutaneous musculoskeletal biopsy performed by Interventional Pathologist for myopathy study. Twenty years of experience.
Abstract	Introduction: Muscle biopsy plays a major role in the final diagnosis of myopathies. Open muscle biopsy is the benchmark procedure, although minimally invasive percutaneous muscle biopsy (MIPMB) has demonstrated comparable diagnostic performance at a lower cost and can be carried out by interventional pathologists. Materials and methods: Muscle biopsies performed from 1997 to 2017 were reviewed and classified according to the type of procedure, whether carried out by an interventional pathologist or another specialist, the diagnosis and the effectiveness of the procedure. Results: 738 muscle biopsies were performed; 32% were open biopsies and 68% MIPMB carried out by pathologist. The muscle most often biopsied was the femoral quadriceps and the most frequent diagnosis was inflammatory myopathies. In only 39 cases (20 open biopsies and 19 MIPMB) was there insufficient tissue for diagnosis. Conclusions: Muscle biopsy proved highly effective as a diagnostic tool as 90% yielded adequate tissue samples. The results obtained with MIPMB performed by interventionist pathologists were comparable to those of open muscle biopsy.
