RESUMO

OBJECTIVES: The aim of this multisite quality improvement study was to evaluate patients' experiences with the patient-centered pathology (PCP) consultation program and to determine whether PCP enhanced their care experience. METHODS: Patients were invited to attend PCP consultations to review their pathology report and slides and have their questions answered by the pathologist privately, with the option to attend the appointment with family members or friends for support. A patient experience questionnaire (PEQ) was administered to patients, who participated voluntarily in the PCP, and survey data were collected and stored in REDCap. Statistical analysis was performed using SAS 9.4 (SAS Institute). RESULTS: Sixty-seven patients (95.5% female) aged 18 to 84 years across 4 institutions completed the PEQ. Overall, 58% and 15.8% of patients had breast and brain tumors, respectively, and 59.7% of tumors were newly diagnosed. Most patients thought it was important for them to learn as much as they could about their health condition. However, the majority of patients reported some degree of difficulty learning about their health condition based on written information, despite 97% having completed high school and/or further education. The majority of patients rated their pathologist as "excellent" across communication metrics. Ultimately, 100% of respondents were satisfied, found their visits to be useful, and would recommend the PCP to other patients. CONCLUSIONS: Patients found that personalized clinical encounters with pathologists improved their understanding of their health condition and their satisfaction with their care experience. Patients thought pathologists communicated respectfully, effectively, and empathetically.

RESUMO

Background: Artificial intelligence (AI) has recently surfaced as a research topic in dermatology and dermatopathology. In a recent survey, dermatologists were overall positive toward a development with an increased use of AI, but little is known about the corresponding attitudes among pathologists working with dermatopathology. The objective of this investigation was to make an inventory of these attitudes. Participants and Methods: An anonymous and voluntary online survey was prepared and distributed to pathologists who regularly analyzed dermatopathology slides/images. The survey consisted of 39 question divided in five sections; (1) AI as a topic in pathology; (2) previous exposure to AI as a topic in general; (3) applications for AI in dermatopathology; (4) feelings and attitudes toward AI and (5) self-reported tech-savviness and demographics. The survey opened on March 13, 2020 and closed on May 5, 2020. Results: Overall, 718 responders (64.1% females) representing 91 countries were analyzed. While 81.5% of responders were aware of AI as an emerging topic in pathology, only 18.8% had either good or excellent knowledge about AI. In terms of diagnosis classification, 42.6% saw strong or very strong potential for automated suggestion of skin tumor diagnoses. The corresponding figure for inflammatory skin diseases was 23.0% (Padj < 0.0001). For specific applications, the highest potential was considered for automated detection of mitosis (79.2%), automated suggestion of tumor margins (62.1%) and immunostaining evaluation (62.7%). The potential for automated suggestion of immunostaining (37.6%) and genetic panels (48.3%) were lower. Age did not impact the overall attitudes toward AI. Only 6.0% of the responders agreed or strongly agreed that the human pathologist will be replaced by AI in the foreseeable future. For the entire group, 72.3% agreed or strongly agreed that AI will improve dermatopathology and 84.1% thought that AI should be a part of medical training. Conclusions: Pathologists are generally optimistic about the impact and potential benefit of AI in dermatopathology. The highest potential is expected for narrow specified tasks rather than a global automated suggestion of diagnoses. There is a strong need for education about AI and its use within dermatopathology.

RESUMO

CONTEXT.­: Vulvar biopsy interpretation and reporting, particularly of vulvar dermatoses, can be challenging in daily practice for both surgical pathologists (SPs) and dermatopathologists (DPs). OBJECTIVE.­: To investigate whether prospective consensus reporting of vulvar biopsies by SPs and DPs would provide value and improve overall diagnostic concordance. DESIGN.­: Consecutive vulvar biopsies during a 6-month period were reviewed prospectively by both gynecologic SPs and DPs. Preliminary, independently generated diagnoses were recorded and then shared in consensus review (SPs+DPs). A third pathologist adjudicated cases without consensus. Multiple data elements were collected for each case: division (SP/DP), age, site, clinical history, diagnostic category, preliminary and final (consensus) diagnosis, need for adjudication, ancillary tests, and diagnostic discrepancy. RESULTS.­: Eighty-four biopsies (48 SP, 36 DP) from 70 patients were reviewed. Forty-two of 84 cases (50%) were neoplastic, 38 of 84 (45%) were reactive/inflammatory, with the remaining (5%) showing both or other features. Independent diagnoses were discrepant in 22 of 84 cases (26%), but consensus review resulted in an agreed-upon diagnosis in all cases, with adjudication required in 6 cases. Independent diagnostic agreement increased over time with a reduction in major and minor discrepancies between the first and second half of the study period. CONCLUSIONS.­: Prospective review of vulvar biopsies by both SPs and DPs can improve overall reporting. Consensus review allows pathologists to gain diagnostic confidence in interpretation of inflammatory (for SPs) and neoplastic (for DPs) vulvar biopsies; therefore, intradepartmental consultation is of value, particularly in select cases.

RESUMO

Primary superficial Ewing sarcoma (psES) cases are exceedingly rare, with fewer than 150 cases reported in the literature. Small case series have suggested differences between psES and Ewing sarcoma (ES) of bone or deep soft tissues: psES appears to have a more indolent course and a higher 5-year overall survival rate. PsES is more common in older adolescent females as opposed to younger males in their peak growth velocity years in bone or deep soft tissue ES. We present a case report of a 17-year-old female with a relatively static nodule on her left thigh for 4 years. Morphologic, immunohistochemical, and molecular evaluations confirmed ES. Patient underwent a gross-total resection and a shortened course of adjuvant chemotherapy without radiation. Cancer gene panel testing found three gene abnormalities (in addition to EWSR1-FLI1 fusion): CCND1 copy number gain, ELF3 copy number loss, and TNFRSF14 copy number loss. To our knowledge, this is the first published case report of psES to include genomic sequencing and the first to report ELF3 and TNFRSF14 abnormalities in ES. Larger series of psES cases with genomic profiling are needed to elucidate a possible genetic etiology for its more indolent clinical course and favorable outcomes.

RESUMO

The ongoing global pandemic of coronavirus disease 2019 (COVID-19) has rapidly disrupted traditional modes of operation in health care and education. In March 2020, institutions in the United States began to implement a range of policies to discourage direct contact and encourage social distancing. These measures have placed us in an unprecedented position where education can no longer occur at close quarters-most notably, around a multiheaded microscope-but must instead continue at a distance. This guide is intended to be a resource for pathologists and pathologists-in-training who wish to leverage technology to continue collaboration, teaching, and education in this era. The article is focused mainly on anatomic pathology; however, the technologies easily lend themselves to clinical pathology education as well. Our aim is to provide curated lists of various online resources that can be used for virtual learning in pathology, provide tips and tricks, and share our personal experience with these technologies. The lists include videoconferencing platforms; pathology Web sites; free online educational resources, including social media; and whole slide imaging collections. We are currently living through a unique situation without a precedent or guidebook, and we hope that this guide will enable the community of pathology educators worldwide to embrace the opportunities that 21st century technology provides.

RESUMO

Pathologists are responsible for rapidly providing a diagnosis on critical health issues. Challenging cases benefit from additional opinions of pathologist colleagues. In addition to on-site colleagues, there is an active worldwide community of pathologists on social media for complementary opinions. Such access to pathologists worldwide has the capacity to improve diagnostic accuracy and generate broader consensus on next steps in patient care. From Twitter we curate 13,626 images from 6,351 tweets from 25 pathologists from 13 countries. We supplement the Twitter data with 113,161 images from 1,074,484 PubMed articles. We develop machine learning and deep learning models to (i) accurately identify histopathology stains, (ii) discriminate between tissues, and (iii) differentiate disease states. Area Under Receiver Operating Characteristic (AUROC) is 0.805-0.996 for these tasks. We repurpose the disease classifier to search for similar disease states given an image and clinical covariates. We report precision@k = 1 = 0.7618 ± 0.0018 (chance 0.397 ± 0.004, mean ±stdev ). The classifiers find that texture and tissue are important clinico-visual features of disease. Deep features trained only on natural images (e.g., cats and dogs) substantially improved search performance, while pathology-specific deep features and cell nuclei features further improved search to a lesser extent. We implement a social media bot (@pathobot on Twitter) to use the trained classifiers to aid pathologists in obtaining real-time feedback on challenging cases. If a social media post containing pathology text and images mentions the bot, the bot generates quantitative predictions of disease state (normal/artifact/infection/injury/nontumor, preneoplastic/benign/low-grade-malignant-potential, or malignant) and lists similar cases across social media and PubMed. Our project has become a globally distributed expert system that facilitates pathological diagnosis and brings expertise to underserved regions or hospitals with less expertise in a particular disease. This is the first pan-tissue pan-disease (i.e., from infection to malignancy) method for prediction and search on social media, and the first pathology study prospectively tested in public on social media. We will share data through http://pathobotology.org . We expect our project to cultivate a more connected world of physicians and improve patient care worldwide.

RESUMO

Soft-tissue sarcomas are a diverse group of rare mesenchymal malignancies accounting for only 1% of all solid adult malignancies. These have been categorized in 12 broad groups by the World Health Organization (WHO) with their recent update in 2013. Majority of them lack specific imaging features serving as imaging conundrums for a radiologist. These are often large masses at presentation as they are asymptomatic or cause vague clinical symptoms. These tumors are challenging for surgeons as well as they find it difficult to achieve complete resection because of complex intra-abdominal anatomy and their close relationship with critical structures. Often, a multidisciplinary approach is required to decide on the most appropriate management for these complex cases so as to provide optimal patient care. Knowledge of the WHO classification, pathologic features and available treatment options will help the radiologist make a meaningful contribution in multidisciplinary discussions of such cases and overall patient care. Liposarcoma (well-differentiated and dedifferentiated liposarcomas), leiomyosarcoma, and gastrointestinal stromal tumor are the 3 most common primary intra-abdominal sarcomas. In part 1 of this article, general features of soft tissue sarcomas and some of the common tumors from WHO category 1-4 found in abdomen and pelvis are discussed. Part 2 will focus on common tumors from remainder of the WHO categories.

RESUMO

BACKGROUND: Genital and extragenital lichen sclerosus (LS) share similar histopathologic features. A recent small series documented elastophagocytosis uniquely in extragenital LS. We evaluated a larger series of LS for elastophagocytosis, elastic fiber loss, and other histopathologic features. We evaluated matrix metalloproteinase (MMP) expression to determine if these proteins play an etiologic role. METHODS: Genital (n = 42) and extragenital (n = 41) LS biopsies were examined for histopathologic features, elastic fiber alteration (Verhoeff van Gieson staining), and MMP-2 and MMP-9 expression (immunohistochemistry). RESULTS: Elastophagocytosis and an interstitial granulomatous pattern were significantly more common in extragenital LS than genital LS (43.9% vs 4.7% and 56.1% vs 9.5%). Extragenital LS had mild/focal elastic fiber loss (43.9%), while genital LS had moderate (61.9%) or marked (19%) loss. MMP-9 was diffusely expressed in histiocytes in both types of LS (genital 97.5%; extragenital 100%). Weak MMP-2 expression was seen in genital (58%) and extragenital (55%) LS. CONCLUSIONS: Extragenital LS, but not genital LS, frequently exhibits elastophagocytosis and interstitial granulomatous infiltrate, and these patterns could contribute to elastic fiber destruction in extragenital LS. While MMP-2 and MMP-9 expression are common in LS, expression did not significantly differ depending on anatomic site and thus is unlikely to explain observed histopathologic differences.

RESUMO

BACKGROUND: Although most cases of Hansen disease (HD) in the United States are imported from endemic areas, a subset of cases are relate to exposure to nine-banded armadillos. Several recent cases of HD in Arkansas occurred in patients who had not traveled to endemic areas and who reported variable degrees of armadillo exposure. OBJECTIVE: The purpose of this study was to report 6 cases of HD diagnosed in Arkansas between 2004 and 2016. The secondary purpose was to explore the correlation between exposure to the nine-banded armadillo as it pertains to transmission of the disease. METHODS: The referring clinician of each patient was contacted to gather information regarding the patient's clinical presentation, armadillo exposure, and travel history. In addition, the Arkansas Department of Health was consulted to review the demographics of individuals diagnosed with HD in the past 15 years and to review the distribution of HD throughout the state of Arkansas. RESULTS: Six domestic cases of HD were associated with both direct and indirect exposure to armadillos. LIMITATIONS: Armadillo exposure may be underreported in patients with HD because of fear of stigmatization and/or lack of access to care. CONCLUSIONS: Direct exposure to armadillos does not appear to be required for transmission of HD making a soil-mediated mechanism of indirect exposure plausible.

RESUMO

Epithelioid fibrous histiocytoma (EFH) is a rare, benign, cutaneous neoplasm. This fibrohistiocytic tumor was once believed to be a variant of fibrous histiocytoma, but EFH is now known to be a distinct entity based on the presence of ALK gene rearrangements in most cases. The pattern of immunohistochemical expression of ALK in EFH in the literature thus far describes both granular cytoplasmic staining and nuclear staining. We present a case of EFH with dot-like Golgi pattern perinuclear ALK expression, a previously undescribed staining pattern. We surmised this unique staining pattern could be due to a novel fusion partner, and using FISH, we confirmed a rearrangement of the ALK (2p23) locus. Further investigation with whole transcriptome sequencing led to the discovery of PRKAR2A-ALK fusion, and the function of this fusion partner reflects a Golgi-predominant localization of the protein. Attention to the distinct immunohistochemical pattern of ALK expression may provide clues to the function of the fusion partner.

RESUMO

BACKGROUND: Strong learner-teacher relationships are associated with more successful learning outcomes. With shortened modular curricula and increased availability of online resources, fostering faculty interaction with preclinical medical students has become more challenging. We sought to enhance learner-teacher relationships by engaging in discussion with preclinical medical students in their own online space. METHODS: We utilized a closed Facebook discussion group, where faculty and students voluntarily joined in informal discussions and shared announcements related to their courses. The closed discussion group allowed only participating students and faculty to see others' posts within the group. This provided a platform to freely interact within the confines of the group while maintaining privacy for the personal Facebook accounts of both faculty and students. We utilized the discussion group through three separate organ system-based modules for 14 weeks. Afterward, students were asked to complete an anonymous, voluntary online survey about their experience. RESULTS: 94.1% (160/170) of enrolled second-year medical students joined the voluntary FB discussion group. There were 214 posts, 628 comments, and 4166 reactions in this discussion group during the three modules. Of the students in the group, 74.4% (119/160) responded to the online survey. Overall, students strongly agreed that the Facebook discussion group fostered better rapport with faculty, helped content learning, and improved emotional well-being. Also, they felt more comfortable seeking academic help after using the discussion group. They reported a slight preference for Facebook over email as a medium for asking questions, but no preference for either as a medium for distributing announcements. Students overwhelmingly recommended that the discussion group should be continued in future years. CONCLUSION: The Facebook discussion group was a free, efficient, and effective method of cultivating the learner-teacher relationship with the preclinical medical students, resulting in reported enhancement of learning and morale.

RESUMO

Pleomorphic fibromas are rare benign cutaneous neoplasms associated with deletion/loss of chromosomes 13q and 17p, where RB1 and TP53 are located, respectively. Herein, we report five cases of pleomorphic fibroma arising in patients with germline TP53 mutations, suggesting a potential link with Li-Fraumeni syndrome. All three patients were female and young (mean age 27) with a strong personal and/or family oncologic history and confirmed pathogenic germline TP53 mutations. In two patients, multiple pleomorphic fibromas were diagnosed. Clinically, the lesions arose at various cutaneous sites and were small (≤2 cm) and raised (4/5). Histopathologically, the tumors were paucicellular, composed of atypical spindled to stellate cells with hyperchromatic and variably pleomorphic nuclei. Mitotic activity was exceedingly low, although rare atypical mitotic figures were seen in one case. Immunohistochemically, the tumor cells were diffusely positive for p16 (3/3) and showed loss of Rb expression (5/5). All cases showed aberrant p53 expression (overexpression in 4, complete loss in 1). The tumors have followed a benign clinical course with no evidence of progression or recurrence. In conclusion, the development of multiple pleomorphic fibromas in a young patient may be a clue to an underlying genetic cancer syndrome involving TP53.

RESUMO

BACKGROUND: Metastatic melanoma in sentinel lymph nodes is often elusive to detect with morphology alone. Per American Joint Committee on Cancer staging guidelines, a single atypical melanocyte in lymph node qualifies as metastasis, whether identified by morphology or immunohistochemistry, but single cell staining must be convincing. We propose that the use of a second immunohistochemical run performed on a single slide will allow for more confident diagnosis of micrometastases. MATERIALS AND METHODS: We designed a technical study to determine whether a second antibody application on previously stained slides can successfully detect the same population of cells. Melanocytic neoplasms were stained with SOX-10 using Ventana Benchmark Ultra stainers, coverslipped, and examined, followed by coverslip removal and application of MART-1 (Ventana A103). The order of antibody application and chromagen detection kit (AP-RED vs. DAB) was reversed to establish reliability and robustness of the protocol. RESULTS: All melanocytes marked with SOX-10 and MART-1, and produced a range of staining quality that varied based on order of stain application and chromagen kit were used. The optimal combination was red MART-1 applied first followed by brown SOX-10 applied second. CONCLUSIONS: Consecutive staining of melanocytes with SOX-10 and MART-1 may improve diagnostic confidence of melanocyte identification, particularly in detection of single cell, micrometastases in sentinel lymph nodes or in situations where dual immunohistochemical stains may be unavailable.

RESUMO

Importance: Dermatofibrosarcoma protuberans (DFSP) may have a deceptively benign clinical appearance, including a nonprotuberant presentation. Patients with DFSP often perceive misdiagnoses and delays in receiving a diagnosis. Use of existing, patient-designed Facebook patient support groups (FBSGs) to recruit large numbers of patients with rare diseases may be an effective novel research method. Objectives: To collaborate with patients with rare disease through social media and answer questions important to both patients and the medical field, including sources of diagnostic delay, risk of recurrence, and flat presentation of DFSP. Design, Setting, and Participants: A multiple-choice survey created by a team of medical practitioners and patients with DFSP was administered to 214 patients with DFSP or family members from international DFSP FBSGs and a nonprofit foundation patient database via Lime Survey from October 30 to November 20, 2015. The survey asked questions designed to determine risk of recurrence and metastasis, surgical outcomes, sources of diagnostic delay, symptoms of recurrence, number of recurrences, scar size, and number of clinicians seen before biopsy. Statistical analysis was performed from January 1, 2016, to April 1, 2019. Main Outcomes and Measures: The study goal was to collect at least 200 survey responses. Results: Of 214 survey respondents (169 females and 45 males; mean [SD] age, 40.7 [12.1] years; range, <1 to 72 years), 199 were patients with DFSP and 15 were family members. Delays occurred between the patient noticing the DFSP lesion and receiving a diagnosis of DFSP (median, 4 years; range, <1 to 42 years). Most patients (112 [52.3%]) believed that they received a misdiagnosis at some point: by dermatologists (35 of 107 [32.7%]), primary care clinicians (80 of 107 [74.8%]), or another type of physician (27 of 107 [25.2%]). The most frequent prebiopsy clinical suspicion included cyst (101 [47.2%]), lipoma (30 [14.0%]), and scar (17 [7.9%]). Many patients first noticed their DFSP as a flat plaque (87 of 194 [44.8%]). Of these lesions, 73.6% (64 of 87) became protuberant eventually. Surgical treatments included Mohs micrographic surgery (56 of 194 [28.9%]), wide local excision (122 of 194 [62.9%]), and conservative excision (16 of 194 [8.2%]). The reported rate of recurrence was 5.4% (3 of 56) for Mohs micrographic surgery, 7.4% (9 of 122) for wide local excision, and 37.5% (6 of 16) for conservative excision. The higher rate of recurrence for conservative excision was significant (P = .001); there was no significant difference in the rate of recurrence between Mohs micrographic surgery and wide local excision (P = .76). Conclusions and Relevance: This study reports what appears to be disease-relevant statistics from the largest survey of patients with DFSP to date. Because of the dissonance between the name of the neoplasm and its clinical presentation, the alternative term dermatofibrosarcoma, often protuberant is proposed. This study suggests that FBSGs are useful tools in medical research, providing rapid access to large numbers of patients with rare diseases and enabling synergistic collaborations between patients and medical researchers.

RESUMO

Patients often cite a history of trauma prior to the diagnosis of a sarcoma. Sparse literature suggests that there may be a link between sarcoma development and trauma. A 10-year review of academic tertiary-referral sarcoma center database was examined to identify patients who developed a sarcoma after having a history of a significant musculoskeletal trauma. A total of 501 patients were treated for a sarcoma during this time period. Six patients were identified as previously having a significant musculoskeletal trauma at the site of sarcoma development. Half of the sarcomas arose in bone and the other half in soft tissue. Five (83%) patients had multiple operations for the injury with 3 (50%) patients having a postoperative wound infection. The average time from injury to development of the sarcoma was 19.8 years. Survival after diagnosis was poor, and 4 (67%) of the patients died due to their metastatic disease within 3 years of diagnosis. Our findings suggest the possibility of post-traumatic sarcomas.
