Vegetative plaque on the left superior eyelid.

Herein we present case report of a 73-year-old female who developed a rapidly growing, ulcerated lesion on her left superior eyelid. Despite treatment for suspected infection, symptoms only marginally improved. Physical examination revealed a diffusely ulcerated multinodular tumour with overlying haemorrhagic and serosanguineous exudate. A shave biopsy led to a diagnosis of primary cutaneous anaplastic large cell lymphoma (pcALCL), a rare CD30+ lymphoproliferative disorder. The patient had no extracutaneous involvement on PET-CT and her prognosis is good given the indolent nature of pcALCL. Differential diagnoses included merkel cell carcinoma, periocular sebaceous carcinoma, lymphomatoid papulosis, and extranodal natural killer/T cell lymphoma. Prognosis for pcALCL is generally good. Treatment recommendation for pcALCL is surgical excision with negative margins for localised disease, while intravenous brentuximab vedotin is suggested for widespread, relapsed, and refractory disease.

Skin Metastasis of Low-Grade Ovarian Serous Carcinoma: A Case Report.

This case report, written with the assistance of ChatGPT, describes a rare manifestation of ovarian serous carcinoma that metastasized to the skin. A 30-year-old female with a history of stage IV low-grade serous ovarian carcinoma presented for evaluation of a painful nodule on her back. Physical examination demonstrated a round, firm, mobile subcutaneous nodule on the left upper back. An excisional biopsy was performed, and histopathologic examination was consistent with metastatic ovarian serous carcinoma. This case highlights the clinical presentation, histopathology, and treatment of cutaneous metastasis of serous ovarian carcinoma. Additionally, this case highlights the value and technique of using ChatGPT to assist in writing medical case reports including outlining, referencing, summarizing studies, and formatting citations.

A prospective pilot study to assess for histologic changes on vulvar biopsies in postmenopausal women with lichen sclerosus treated with fractionated CO2 laser therapy.

OBJECTIVES: To investigate the histologic characteristics of vulvar tissues before and after completion of fractionated carbon dioxide (CO2 ) laser therapy (FxCO2) for vulvar lichen sclerosus (LS). The secondary objective was to assess subjective improvement in symptoms via the Skindex-16 questionnaire. METHODS: This prospective single-arm study was conducted from April 2021 to August 2022 at one academic medical center. Ten postmenopausal women with biopsy-proven LS planning FxCO2 laser treatment were enrolled. Exclusion criteria included prior transvaginal mesh for prolapse, topical corticosteroid use within 8 weeks, prior pelvic radiation, malignancy, active genital infection, or pregnancy. The vulvovaginal SmartXide2-V2-LR laser system fractionated CO2 laser (DEKA) was utilized to treat visually affected areas of vulvar and perianal LS with a single pass. Subjects underwent three treatments 4-6 weeks apart. Subjects completed the Skindex-16 questionnaire and had vulvar biopsy at baseline and at 4 weeks after completion of fractionated CO2 laser therapy. Blinded histologic slides were scored by one dermatopathologist (Michael A. Cardis) rating from 1 to 5 the degree of dermal sclerosis, inflammation, and epidermal atrophy. Change scores were calculated as the difference between pre- and post-treatment scores for each subject. RESULTS: The 10 subjects enrolled had a mean age of 61 and most were white, privately insured, and had a college/graduate-level education. Post-fractionated CO2 laser treatment vulvar biopsies showed significant improvement in sclerosis and epidermal atrophy compared with pretreatment baseline biopsy specimens (p < 0.05) with no statistically significant change found in inflammation score. Skindex-16 and FSFI scores showed a trend towards improvement (p > 0.05 for both). A statistically significant correlation was found between change in sclerosis and Skindex-16 symptoms scores with an average change of 21.4 units in Skindex-16 symptoms score for every one-point change in histologic sclerosis score (p = 0.03). CONCLUSIONS: In postmenopausal women with vulvar LS undergoing fractionated CO2 laser, symptomatic improvements correlated with histologic change in degree of sclerosis on vulvar biopsy. These results demonstrate FxCO2 laser therapy as a promising option for the treatment of LS and suggest that further studies should assess degree of sclerosis on histopathology.

Analyzing disparities in access to teledermatology compared with dermatology clinic visits before, during, and after COVID-19 quarantine.

The COVID-19 pandemic has caused significant changes in dermatologic care, likely exacerbating health disparities for specific minority populations. The use of teledermatology has also become more prevalent during this period. The aim of this study was to determine if the proportion of teledermatology versus office-based visits varied significantly during three study periods of the COVID-19 pandemic. The secondary objective was to determine whether there are significant differences in the use of office-based dermatology versus teledermatology care across the following demographic subgroups: insurance type, race/ethnicity, age, and language during the same periods. A chart review of dermatology visits in electronic medical records at a tertiary referral center in Washington, DC, was conducted. The overall telehealth visit rate was 0% in the prequarantine period, 61.12% during the quarantine period, and 10.59% in the postquarantine period. After assessing telehealth utilization rates among the demographic subgroups, we noted that Medicaid users, Black patients, 64-year-olds or older, and English speakers may benefit the least from telehealth services. Teledermatology use necessitated by the COVID-19 pandemic may have promoted health care disparities for specific marginalized populations.

A widespread blistering eruption: diffuse cutaneous mastocytosis.

Diffuse cutaneous mastocytosis with bullous formation is a rare childhood disease. We report a 5-month-old male who presented with a 3-week history of cutaneous bullae and pruritus. On examination, he had erythema of the cheeks bilaterally and diffuse slightly hyperpigmented, indurated skin on his trunk and abdomen. There were tense vesicles, bullae, and erosions linearly arranged on his trunk and extremities. Both the laboratory and imaging workup were normal. Subsequently, a punch biopsy of a vesicle on the abdomen was obtained and findings confirmed a diagnosis of diffuse cutaneous mastocytosis. An EpiPen(r) was prescribed due to the slightly increased anaphylaxis risk compared to other forms of mastocytosis. There are many purported triggers of diffuse cutaneous mastocytosis and there is currently no known cure which makes management of this disease challenging. This case highlights a rare condition for which official treatment guidelines do not exist. A prompt dermatologic diagnosis is necessary to ensure proper workup and regulation is in place.

"Knife-cut" intertriginous ulcers related to herpes simplex virus in three patients.

Linear intertriginous erosions and ulcerations related to herpes simplex virus (HSV) infection have been reported in patients with underlying immunosuppression. This rare presentation of HSV seems to occur predominantly in patients undergoing treatment of hematologic malignancies and rheumatologic conditions. Herein, we report three cases of linear "knife-cut" ulcerations in patients who were not undergoing active pharmacologic immunosuppressive therapy and lacked coexisting malignancy or autoimmune disease. Close examination of the skin folds for HSV infection is warranted to rule out disseminated infection as early intervention can be lifesaving.

Gastric carcinoma's primary presentation as multiple cutaneous nodules throughout the body.

Cutaneous metastasis resulting from internal primary tumors remains a rare phenomenon. The prompt recognition of these metastases is important, as they are an indicator of advanced disease and poor prognosis. We report the case of a 44-year-old Caucasian man presenting with a four-month history of multiple cutaneous nodules on the face, trunk, and upper extremities. Results from skin biopsy revealed strands and cords of atypical cells concerning for poorly differentiated metastatic carcinoma. An esophagogastroduodenoscopy was performed and a poorly differentiated signet-ring type invasive adenocarcinoma at the lesser curvature of the stomach was found. As the cancer had already metastasized to the skin and bones, the patient was started on chemotherapy with an oxaliplatin-based regimen and denosumab for the bone metastases, with resultant objective response and diagnostic control for greater than one year to the present date.
