Proficiency in dermatopathology is important for comprehending the mechanisms of skin diseases and determining efficacious clinical management. Dermatopathology learning is a core requirement for both dermatology and pathology residencies. Many traditional educational methods have been utilized over decades for teaching our residents. In the recent digitized era, technological advances are impacting the study and practice of medicine. Several innovative tools have become available that complement the conventional learning model. This contribution provides guidelines for establishing a robust dermatopathology rotation for residents and insights into the present and future advances in novel educational tools. Dermatopathology is an ever-growing body of knowledge. It takes years to accumulate practical knowledge of this discipline and requires a continuing effort to maintain and keep it updated. This journey of learning starts during the early years of postgraduate medical education. Attaining competency in dermatopathology is vital for both dermatology and pathology residents. The earlier the exposure they receive, the better the foundation and understanding of cutaneous disease processes they develop. Comprehensive training in the subspecialty of dermatopathology is critical for their medical education and the future practice.

According to the Federal Council of Medicine's demographic data from 2020, the medical specialty with the highest number of women is dermatology; with 77.9% within the total of 9,078 specialists. The male/female ratio is 0.28, that is, for each man, there are more than 3 women Dermatologists. Analyze the participation of women in Brazilian dermatology and their representation in leadership positions through data review. A literature review of the National Library of Medicine PubMed database was performed in May 2022 and data review of the SBD database. According to the Brazilian Society of Dermatology (SBD), about 80% of its associated Doctors are women. Despite this correlation, since its foundation in 1912, the SBD has already had 62 directorates, of which 53 were known to be presided over by men and 4 of them are unknown. Among the directorates that are known, only five (8.62%) were chaired by women.

This study focuses on how skincare professionals, such as dermatologists, plastic surgeons, and dermal clinicians, can apply strategies in publishing credible social media content related to the skin. The study interviewed 10 participants and asked questions about the skincare advice they seek from social media. Analysis of the results revealed the prominent themes of education, delivery of information, credibility, trustworthiness, and relatability; however, visual characteristics of how the information was presented, formed the most significant theme. The risk of the public following advice from nonprofessionals on social media includes miscommunication of ideas and adverse reactions that could result in undesirable outcomes; hence, skincare professionals should include correct advice while producing social media content.

A woman in her twenties, with a non-consanguineous marriage, presented to the dermatology clinic with asymptomatic lesions on her face, neck, trunk, and extremities for the past 12 years. The general physical and systemic examination was unremarkable. Cutaneous examination revealed multiple hypopigmented to a few hyperpigmented, slightly scaly tinea versicolor-like macules distributed predominantly on the neck, upper portion of the back, and distal parts of the extremities (Figures 1-5). There were muultiple, slightly erythematous to violaceous flat-topped wart-like papules and plaques were discovered on the arms (Figures 1 and 2), with seborrheic keratosis-like lesions on the face (Figure 5). Baseline investigations, such as complete blood count (CBC), liver function test (LFT), kidney function test (KFT), and plasma glucose levels, were normal. Serologic tests conducted for human immunodeficiency virus (HIV)-1 and HIV-2, and hepatitis B and C were nonreactive. Skin lesion potassium hydroxide (KOH) examination from tinea versicolor-like lesions was negative for fungal elements. Skin biopsies were performed from tinea versicolor-like macules present on the upper portion of the back, flat wart-like plaque on the dorsum of the left hand, and hyperpigmented scaly plaque in the extensor area of the left leg. Histopathologic examination revealed parakeratosis, hyperkeratosis, and acanthosis with swollen keratinocytes, bluish-gray cytoplasm, and rounded nuclei with prominent nucleoli. No dysplastic changes/atypia or mitotic figures (Figures 6 and 7), plus occasional perinuclear halo (a vacuolated area that surrounds the nucleus), were observed. Following clinicopathologic correlation, the patient was diagnosed with epidermodysplasia verruciformis (EV, or Lewandowsky and Lutz's dysplasia).

Libtayo® (cemiplimab-rwlc) injection for intravenous use was recently approved by the US Food and Drug Administration (FDA) for locally advanced basal cell carcinoma (laBCC) and metastatic basal cell carcinoma (mBCC), both being the advanced stages of BCC. In the past, it was approved by the FDA for the treatment of metastatic cutaneous squamous cell carcinoma (mCSCC) and locally advanced cutaneous squamous cell carcinoma (laCSCC), both being the advanced stages of CSCC. Cemiplimab is a monoclonal antibody that works by blocking the programmed death-1 pathway. In two open-label, single-arm, phase 2 studies, cemiplimab was investigated for the treatment of advanced stages of BCC (study 1620, NCT03132636) and advanced stages of CSCC (study 1540, NCT02760498). The primary endpoint was objec-tive response rate (ORR) per independent central review. In the study 1620, both mBCC and laBCC received cemiplimab 350 mg every 3 weeks. ORR was 21% (6/28) and 31% (26/84) in the mBCC and laBCC groups, respectively. In the study 1520, mCSCC was divided into two groups: one receiving cemiplimab 350 mg every 3 weeks (Q3W) and another receiving 3-mg/kg cemiplimab every 2 weeks (Q2W); the third group, laCSCC, received cemiplimab 3 mg/kg every 2 weeks. ORR was 41% (23/56) in the Q3W group, 49% (29/59) in the Q2W group, and 44% (34/78) in the laCSCC group. An acceptable safety profile and antitumor activity was discovered in patients treated with cemiplimab. The recommended dosage for cemiplimab to treat advanced stages of BCC and CSCC is 350 mg every 3 weeks administered intravenously over 30 min.

A 19-year-old girl presented with symmetric and bilateral hyperpigmentation, an indurated lesion that initially appeared on the axillary fold at the age of 14, which then extended to the lower back, anterior aspect of both thighs, and popliteal fold. No hypertrichosis was observed (Figure 1).The patient was the youngest of the four children, born from the first-degree consanguineous marriage. She was born at full term and weighed 2,420 g at birth. No similar patient was present in the family. The patient experienced delayed motor acquisition and stature growth (3rd percentile) until the age of 4. Right hypoacusis was diagnosed at the age of 6. She developed hallux valgus, flexion contracture of the fin-gers and toes, barrel deformity of the anterior thorax, and recurrent fever. The laboratory tests, including fasting blood glucose, -triglycerides, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) were normal. Her abdominal, pelvic, and transthoracic ultrasound scans were normal, with no hepatosplenomegaly, lymphadenopathy, or cardiac abnormalities. Histologic analysis demonstrated patchy acanthosis of the epidermis, with orthokeratotic hyperkeratosis. Keratinocyte hyperpigmentation and spongiosis at certain areas were observed with moder-ate inflammation because of the infiltration of lymphocytes, histiocytes, and plasma cells. Immunohistochemical analysis showed macrosialin (CD68+) and common gamma chain (γc) CD132. Germline mutations in the SLC29A3 gene were not analyzed. The patient was prescribed dermocorticoids with depigmentation therapy, which demonstrated moderate clinical evolution.

A 32-year-old patient complained of three slow-growing subcutaneous nodules on her right labius majus, present for 3 years. Her past medical history was unremarkable. Cutaneous examination revealed three subcutaneous nodules of 1 cm diameter firmly adherent to the underlying tissues, located on her right labium majorum (Figure 1). Regional lymph nodes were not enlarged. She underwent an excision biopsy of a subcuta-neous nodule under local anesthesia. The gross specimen was firm, white and fleshy in appearance. A skin biopsy was performed, and histological findings revealed a non-encapsulated dermal nodule composed of clusters of polygonal cells with small central nuclei and abundant eosinophilic cytoplasm (Figure 2a). The tumor cells formed sheets and nests irregularly infiltrating between collagen bundles. There was no significant cyto-logic atypia and mitotic features. There were no necrosis and hemorrhage. The cells were positive for S-100 immunostain (Figure 2b). Hence, the diagnosis of benign vulvar granular cell tumor was assessed. The patient underwent surgical excision of the subcutaneous nodules with no recurrence at 2 years.
