    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.

    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.

    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.

    Abstract Introduction: The Sydney system proposal for the study and reporting of lymphadenopathy by fine-needle aspiration (FNA) constitutes one of the first attempts to standardize this procedure. Here, we review its applicability.
    Materials and methods: A retrospective study in which all ultrasound-guided FNAs (USFNAs) of superficial lymphadenopathy (palpable or not) performed by interventional pathologists in 2 specialized hospital centers were quantified over 2 years. The procedure was systematized, and the diagnoses were reclassified according to the Sydney system categories.
    Results: We analyzed 363 USFNAs of lymphadenopathies. The distribution of cases by categories was as follows: insufficient (n = 13; 3.58%), benign (n = 208; 57.30%), atypia of uncertain significance (n = 7; 1.93%), suspicious (n = 21; 5.79), and malignant (n = 114; 31.40%). The risks of malignancy calculated for categories I, II, III, IV, and V were 27%, 3%, 50%, 100%, and 100%, respectively.
    Conclusion: The implementation of the Sydney system allows the systematization and standardization of the lymph node FNA methodology, with increased efficacy and efficiency. Assimilating the recommendations enables the qualification of the diagnostic procedure.
