Cutaneous "Microcystic" Microsecretory Adenocarcinoma With Marked Adnexal Hyperplasia: A Simulant of Microcystic Adnexal Carcinoma.

ABSTRACT: Microsecretory adenocarcinoma (MSA) was first described in 2019 as a low-grade salivary gland neoplasm of intraoral origin with distinct histopathologic features and a characteristic MEF2C::SS18 fusion. Recently, skin was also identified as a primary site for MSA in a report by Bishop et al. Due to its rarity and resemblance to other adnexal tumors, MSA is a challenging diagnosis. Herein, we present a case of cutaneous MSA that was unique for the presence of a significant microcystic component and marked adnexal hyperplasia, which mimicked myxoid microcystic adnexal carcinoma (MAC). A 58-year-old presented with a 1 year history of an enlarging eyelid nodule. Histopathologic analysis revealed dermal tumor composed of small tubules containing inspissated bluish mucinous material. Accompanying marked adnexal hyperplasia and many microcysts were also present. Tumor cells expressed S100 protein, which is distinct from MAC, while p63 immunohistochemistry showed marked loss of myoepithelial labeling, as is common in primary adenocarcinomas. Next generation gene sequencing detected the characteristic MSA fusion protein MEF2c::SS18. We report a novel presentation of MSA that simulated MAC because of the presence of associated microcystic change. The presence of S100 immunopositivity and the identification of MEF2C::SS18 fusion confirmed the diagnosis of cutaneous MSA.

Eyebrow and Eyelash Loss in Patients With Cancer.

Though it is widely acknowledged that cancer treatments cause hair loss on the scalp, there are limited data on how they affect eyebrow and eyelash hairs. Patients with eyebrow and eyelash loss, or madarosis, seek various treatment options ranging from camouflage techniques with makeup, permanent tattoos, and prescription medications. Though not yet studied in patients with cancer-induced madarosis, techniques such as scalp cooling, cryotherapy, and topical vasoconstrictors are promising preventative options. More robust research is needed to improve both the quality and quantity of available treatment and preventative options. There is a clear need for dermatologists to play a role in supportive oncodermatology for patients who experience eyebrow and eyelash loss secondary to chemotherapy, endocrine therapies, and radiation therapy.

Characterization of the role of Facebook groups for patients who use scalp cooling therapy: a survey study.

Since the emergence of scalp cooling therapy (SCT) for the prevention of chemotherapy-induced alopecia (CIA), support groups on social media platforms for interested patients have surfaced. Though there are over 20,000 active members across SCT Facebook groups, little is known about how members use this platform. A 23-question survey was posted in five scalp cooling Facebook groups, reaching 219 women. Results indicated that these Facebook groups play clear roles in providing the following: (1) a supportive community for patients, (2) instructions for SCT use, (3) advice regarding insurance coverage and reimbursement, and (4) recommendations for over-the-counter products for hair loss. Despite reported interest in hair loss products, only 5% of patients sought medical treatment from dermatologists. Due to group-specific access restrictions, private Facebook groups provide patients with a protected platform to learn more about SCT from both those with personal experience and SCT company specialists. Providers may consider recommending these online groups to interested patients during the scalp cooling counseling process. As patients with CIA express a growing interest in over-the-counter hair, eyebrow, and eyelash products, it is important for dermatologists to be aware of where their patients obtain recommendations, and further, if these recommendations have clinical evidence of efficacy.

Trainee Perspectives of Private Equity's Impact on Ophthalmology.

Objective The accelerated involvement of private equity (PE) in ophthalmology has many potential implications for the future of the field. The aim of this study was to evaluate trainee perspectives on PE's impact on ophthalmology. Methods An electronic survey was sent to trainees via an online ophthalmology research newsletter. The survey assessed for career goals and perspectives on the involvement of PE and its impact across a variety of attributes. Results A total of 41 United States-based respondents responded to the survey, 68% were medical students and 32% were residents or fellows. Seventy-eight percent of respondents reported they would not consider working for a PE-owned practice. There was a negative perceived impact of PE for physician autonomy, long-term physician income, career advancement, and quality of care. There was a positive perceived impact for the number of physician extenders, more referral sources, financial support, bargaining with insurance companies, starting physician salary, and administrative burden. All respondents agreed (76% strongly agree, 24% somewhat agree) that education about practice options and ownership structures is important to include in residency program education, with preferred modalities of small group discussions and on-site learning. Conclusions Trainees broadly perceive PE to negatively impact the practice of ophthalmology. While there were attributes perceived to be positively impacted by PE, these were not felt to be as important as those which may be negatively affected. New modalities for education about practice ownership options are necessary, and small group discussions and on-site learning may be of the highest yield for trainees.

Factors influencing scalp cooling discussions and use at a large academic institution: a single-center retrospective review.

PURPOSE: Chemotherapy-induced alopecia (CIA) is a stigmatizing and psychologically devasting side effect of cancer treatment. Scalp cooling therapy (SCT) is the most effective method to reduce CIA, yet it is underutilized. We investigated factors that may impact scalp cooling discussion and use. METHODS: We performed a retrospective review of cancer patients from 2000 to 2019 who had documentation of SCT discussion in the electronic medical record. The University of Michigan Rogel Cancer Center registry was used to identify the total number of cancer patients eligible for SCT during 2015-2019. Chi-square tests were used for outcome and patient characteristic comparisons (p < 0.05). RESULTS: From 2000 to 2019, 194 patients had documentation of SCT discussion. Of those, 72 (43.6%) used SCT, 93 (47.9%) did not use SCT, and the remaining 29 (17.8%) had unknown SCT use. A total of 5615 cancer patients were eligible for SCT from 2015 to 2019. As compared to those who did not have documented SCT discussions, patients who had documentation of SCT discussions in that period (n = 161, 3.0%) were more likely to be female, have breast cancer, be less than 45 years old, and live in a zip code with average income > US $100,000 (all p < 0.0001). Between 2015 and 2019, 57 patients (1.02%) used SCT. On univariate analysis, patient-initiated conversation about SCT (p = 0.01) and age less than 65 (p = 0.03) were significantly associated with decision to use SCT. CONCLUSION: There were distinctions in the types of patients who have documented discussions about SCT. Improving patient knowledge about the availability of SCT and increasing access to this technology for all eligible cancer patients may enable more patients to achieve improved quality of life by reducing or preventing CIA.

Identifying Barriers and Facilitators to Scalp Cooling Therapy Through a National Survey of the Awareness, Practice Patterns, and Attitudes of Oncologists.

PURPOSE: Scalp cooling therapy (SCT) is the most effective method to reduce chemotherapy-induced alopecia (CIA), a highly distressing side effect of cancer treatment. Despite data supporting SCT efficacy and safety, SCT use in the United States is not widespread. Oncologists' interactions with scalp cooling were examined to identify facilitators and barriers to SCT implementation. METHODS: A 33-question survey was distributed through the ASCO Research Survey Pool to a nationally representative, random sample of 600 oncology providers. Outcome measures included knowledge of SCT, frequency of initiating conversations about SCT with patients, degree of support, and barriers for SCT. Significance was defined as P < .001. RESULTS: Of 155 (25.8%) responding providers, 62% of providers were in favor of SCT always or most of the time, but only 26% reported initiating discussions about SCT always or most of the time. Providers who treat breast cancer (P ≤ .0001), those who report being very familiar with SCT (P ≤ .0001), those who report having read SCT literature in the past 2 years (P ≤ .0001), and those who work at a facility with machine SCT (P ≤ .0001) were significantly more likely to initiate conversations with patients about SCT. Financial concerns (58%) were the primary reason for not recommending SCT use; efficacy (31%), staff or facility (24%), and safety (15%) concerns were also noted. Although safety concerns have decreased markedly over time, 14% of providers report patients who continue to express these concerns and 17% of providers see safety issues as barriers to supporting SCT. CONCLUSION: Our findings suggest that oncology provider familiarity and experience with SCT lead to increased support for scalp cooling, which may ultimately result in greater availability and utilization of SCT when indicated.

The Malignancy Potential of Porokeratosis: A Single-Center Retrospective Study.

Background Porokeratosis (PK) is a rare group of keratinization disorders. While the overall prognosis of PK is favorable, malignant transformation of PK to skin cancer has been reported in 6.9% to 11.6% of the cases. Prior estimates of malignant transformation of PK have been based on reviews of published cases, which introduces possible publication bias. We aim to eliminate this potential bias and quantify the characteristics, risk factors, and malignancy potential of PK. Methodology A single-center retrospective chart review of patients with a diagnosis of PK was conducted. Results In this study, 6.4% to 16.4% of histologically confirmed PK lesions demonstrated malignant transformation. A higher proportion of disseminated superficial actinic porokeratosis (DSAP) cases (as high as 29.3%) showed malignant transformation compared to PK of Mibelli (as high as 6.0%). Out of the two cases of linear PK, both demonstrated malignant transformation. Conclusions In summary, PKs are at risk for malignant transformation, and patients with DSAP and linear PK, in particular, should receive more long-term surveillance. Limitations of this study include the inability to control for confounding factors due to the retrospective nature and the small size of our cohort.

Dermatology resident perspectives on practice ownership structures and private equity-backed group practices.

Recently, dermatology group practice ownership structures have changed, as private equity (PE) consolidates independent dermatology practices to create larger groups. Currently, little is known about how dermatology residents perceive practice ownership structures, including those that are owned by PE. One hundred thirty-seven residents from 32 dermatology residency programs responded to a 21-question anonymous survey. Approximately 65% of residents in this study were not open to working for PE-backed practices, and their negative perceptions of how PE influences quality of care, long-term salary, and physician autonomy were associated with their unwillingness to work at a PE-backed practice. Most residents in this study valued education about practice ownership structures, and approximately 43% of respondents did not feel adequately informed about practice options during residency. Future studies should evaluate how PE ownership of group practices influences practice parameters, including quality of patient care, physician autonomy, and long-term salary.
