A case report of acute promyelocytic leukemia with mycosis fungoides.

RATIONALE: Acute promyelocytic leukaemia (APL) is a rare subtype of acute myelogenous leukaemia. With advances in treatment regimens, namely, introduction of all-trans-retinoicacid, outcomes have drastically improved, its side effects should not be ignored. Mycosis fungoides is one of the side effects of all-trans-retinoicacid treatment, but it may also be a clinical manifestation before disease progression. However, it rarely appears and is easily overlooked. This leads to being easily misled during the treatment process, affecting the treatment plan, and resulting in adverse consequences. Therefore, early identification and judgment can not only provide appropriate treatment options, but also prevent and treat further disease progression. PATIENT CONCERNS: The patient was hospitalized for pancytopaenia. After completing the examination, the patient was finally diagnosed with acute promyelocytic leukaemia (acute myelogenous leukaemia-M3). We administered tretinoin and arsenous acid. Evaluation of the treatment effect on the 7th day after chemotherapy showed that the bone marrow morphology showed complete remission. After the second course of chemotherapy, the patient developed red miliary macular papules, which gradually worsened. After completing relevant inspections, Considering that the cases was complicated with skin mycosis fungoides, the patient was treated with budesonide ointment and methylprednisolone as chemotherapy. DIAGNOSES: Upon examination, the patient was initially diagnosed with acute promyelocytic leukaemia. Evaluation of the treatment effect on the 7th day after chemotherapy showed that the bone marrow morphology showed complete remission. After the second course of chemotherapy, we discovered the patient was diagnosed with skin mycosis fungoides. INTERVENTIONS: Systemic chemotherapy is first given when a patient was diagnosed with acute promyelocytic leukaemia. After the patient happened skin mycosis fungoides, We have adjusted the treatment plan and supplemented it with other treatment plans based on the original chemotherapy, After 2 months of treatment, his condition gradually improved. OUTCOMES: All-trans-retinoicacid in the treatment of APL must be given attention because mycosis fungoides should not only be distinguished from infectious diseases but also be further assessed with regard to disease progression and metastasis. LESSONS: Acute promyelocytic leukemia needs to be treated with arsenic trioxide. All-trans-retinoicacid in the treatment of APL must be given attention mycosis fungoides. Early diagnosis can guide accurate treatment, which is of great help in alleviating the pain of patients and improving the cure rate.

Clinical, histopathological and immunohistochemical evaluation of ultraviolet A1 treatment in early-stage mycosis fungoides.

BACKGROUND/PURPOSE: Mycosis fungoides (MF) is the most common variant of cutaneous T-cell lymphomas primarily involving the skin. Early-stage MF is characterised by non-specific skin lesions and non-diagnostic biopsies. While skin-focused treatments, such as PUVA and narrowband UVB (nbUVB), are the most frequently recommended treatments, the UVA1 efficacy has been researched in recent years. The purpose of this study was to evaluate the clinical, histopathological and immunohistochemical aspects of UVA1 treatment in patients with early-stage MF. METHODS: The modified severity weighted assessment scale (mSWAT) was used for total skin body scoring before and after treatment. Skin punch biopsies were taken from the patients before and after treatment. UVA1 therapy was performed five times each week. RESULTS: This study included 26 patients with early-stage MF. The total number of UVA1 sessions varied between 15 and 34. Complete response was observed in 8 (30.8%) of 26 patients (30.8%). The median mSWAT score decreased statistically significantly from 7.1 to 2.0 after treatment (p < .001). Histopathological complete response was observed in 2 (9.5%) of 21 patients. A statistically significant decrease in dermal interstitial infiltrate was observed on histopathological examination after treatment (p = .039). Epidermal CD4/CD8 levels decreased statistically significantly higher from a median of 2.5-1.2 in the complete clinical response group after treatment (p = .043). CONCLUSION: According to our results, UVA1 treatment has an effect on early-stage MF in terms of clinical, histopathological and immunohistochemistry.

Multiple Bowen's disease due to long-term narrow-band ultraviolet B phototherapy: A case report and literature review.

OBJECTIVE: By presenting a case study on multiple instances of Bowen's disease and the consistent use of narrow-band ultraviolet B (NB-UVB) phototherapy over a three-year period, our aim is to enhance the comprehension of domestic clinicians regarding the disease. Additionally, we seek to review existing literature, encouraging dermatologists to consider clinical secondary primary lesion diagnoses. METHOD: Our approach involves analyzing a diagnosed case of multiple Bowen's disease, examining clinical manifestations, histopathology, imaging results, and treatment methods related to NB-UVB phototherapy. We aim to facilitate discussion and understanding through a comprehensive literature analysis. RESULTS: An elderly male with a 30-year history of psoriasis vulgaris initiated continuous NB-UVB therapy three years ago. A year later, he developed red patches and plaques with distinct borders and scaly surfaces on his face, trunk, lower extremities, and scrotum. Histopathological examination confirmed Bowen's disease. Treatment involved liquid nitrogen cryotherapy, with no recurrence observed during the one-year follow-up. CONCLUSION: This case highlights that Bowen's disease, typically solitary, can manifest as multiple instances, especially in individuals with a history of psoriasis vulgaris. While NB-UVB stands as the primary treatment for psoriasis vulgaris, caution is warranted due to the potential risk of skin tumor induction with prolonged high-dose usage. Clinicians should be vigilant in monitoring and assessing the long-term implications of such therapies.

A Case Series on the Use of Brentuximab Vedotin for the Treatment of Mycosis Fungoides.

BACKGROUND: Brentuximab vedotin (BV) is an anti-CD30 monoclonal antibody that appears to be more effective against CD30-expressing cutaneous T-cell lymphoma (CTCL) compared to current standard-of-care treatments.   Objective: To determine the real-world efficacy and adverse effects of BV use in patients with mycosis fungoides (MF) who were treated with BV at Atrium Health Wake Forest Baptist Medical Center. METHODS: Study staff performed a retrospective chart review of patients diagnosed with MF who were prescribed BV at Atrium Health Wake Forest Baptist Comprehensive Cancer Center. RESULTS:   Regardless of their response to BV, all patients in our cohort had higher CD30 positivity on subsequent biopsies compared to their initial skin biopsy.  Conclusions: Improved understanding of appropriate CD30 testing and evaluation will allow for quicker invention of patients with BV responsive CTCL.  J Drugs Dermatol. 2023;22(12):e33-e34.    doi:10.36849/JDD.6981e.

Evaluation of skin cancer screening in Germany - participation, tumor detection and interval tumors based on SHI data.

BACKGROUND AND GOALS: The rising incidence of skin cancer in Germany has increased the need for secondary prevention measures. For this purpose, a statutory skin cancer screening for insured persons aged 35 and older was introduced on 1 June 2008. The aim of this work package in the Innovation Fund project "Perspectives of a multimodal evaluation of early skin cancer detection" (Pertimo) was to test an evaluation of skin cancer screening using secondary data. PATIENTS AND METHODS: The data basis was statutory insured persons of the DAK Health from the age of 35 who were insured as of 31 December 2010 and were followed up until the end of 2015. The rates of participation, skin tumors detected in skin cancer screening (tumor detections), and interval tumors that occurred within two years after a finding-free skin cancer screening were calculated. RESULTS: The biennial skin cancer screening take-up rate in 2014 and 2015 was 33.6% for women and 32.6% for men. Of those screened, 4.2% had a skin cancer finding (tumor detection) in the course of skin cancer screening. Of all incident skin cancer diagnoses (2012-2015), 50.1% were detected in skin cancer screening. In 1.5% of the insured persons with skin cancer screening without findings, an incidental skin tumor was diagnosed in the following two years (interval tumor). CONCLUSIONS: The data from the statutory health insurance mapped the skin cancer screening occurrence in Germany and highlighted the importance of dermatologists in the screening process. The analysis provided important new insights.

[The molecular genetic aspects of basal cell carcinoma from the position of population health preservation].

The exploration of molecular genetic mechanisms that underlie carcinogenesis, hereditary factors of various oncological diseases, including basal cell carcinoma, the most common type of skin cancer is especially actual and significant for target strategies of public health. The diagnosis of basal cell carcinoma is based on complex clinical, radiologic and genetic examination data. The further research in the field of somatic or hereditary mutations in genes associated with basal cell carcinoma, including Patched 1 (PTCH1), Patched 2 (PTCH2), Smoothed (SMO) continue to be topical. The strategies of primary prevention of basal cell carcinoma, discussions of complex issues of decision-making concerning treatment at primary health care level, training courses and development of guidelines for general practitioners and interdisciplinary recommendations for effective early diagnosis and comprehensive care of basal cell carcinoma are to be suggested.

[Current Management of Basal Cell Carcinoma]. / Aktuelles Management des Basalzellkarzinoms.

For the management of basal cell carcinoma, the primary performance of a risk stratification, which is decisive for the further diagnostic and therapeutic steps, is becoming increasingly important.Various non-invasive methods are available to confirm the clinical diagnosis. Histological confirmation of the diagnosis is recommended in unclear cases. In poorly displaced lesions, preoperative cross-sectional imaging of the tumor area should be performed to exclude osseous infiltration.The gold standard in treatment remains surgery, which should be performed by means of micrographically controlled surgery if possible. In addition, there are other therapeutic methods such as radiotherapy or a number of topical therapy options (photodynamic therapy, cryotherapy or application of 5-fluorouracil or imiquimod), which can be used in certain cases. Also for advanced or metastatic basal cell carcinoma, effective drugs are available in the form of the hedgehog inhibitors, for which there is now several years of application experience with regard to efficacy and handling of adverse events. With the PD-1 inhibitor cemiplimab, a further therapeutic option for non-operable or metastatic tumors has been available since June 2021.The most important preventive measure is consistent textile or chemical UV protection in already affected individuals. In addition, nicotinamide and celecoxib can be used orally for prevention. For follow-up, the current S2k guideline recommends regular self-monitoring and standardized medical check-ups.

Paediatric Mycosis Fungoides: Clinical Variants, Treatment Modalities and Response to Therapy.

Mycosis fungoides is a rare cutaneous lymphoma in the paediatric population. The aim of this study was to examine the epidemiological, clinical, and histological characteristics, as well as the treatment modalities and response to therapy of paediatric patients with mycosis fungoides. This retrospective cohort study reviewed the records of 37 paediatric patients treated at Rambam Medical Center, Israel, between 2013 and 2021. Extracted data included epidemiology, clinical presentation, histological reports, infiltrate clonality status, treatment modalities and response to therapy. The mean follow-up period was 60 months. All patients were diagnosed with stage IA or IB disease. Folliculotropic mycosis fungoides was the most prevalent variant (49%). Most patients were treated with phototherapy (90%), with a response rate of 85%, and a complete response rate of 55% after the first course. There were no significant differences in response to phototherapy between the folliculotropic or other variants (p = 0.072). Similarly, delayed diagnosis, atopic diathesis, clonality, phototherapy type or number of treatments, were not associated with response to therapy, while protracted phototherapy was associated with prolonged remission. In conclusion, mycosis fungoides in the paediatric population is an indolent disease with a favourable prognosis and potentially prolonged response to phototherapy.

Biologic therapy is associated with malignancies among Israeli patients with rheumatoid arthritis: A population-based study.

AIMS: To examine whether biologic disease-modifying anti-rheumatic drugs (bDMARDs) are associated with increased risk of malignancy among Israeli patients with rheumatoid arthritis (RA). METHODS: We identified RA patients meeting specified inclusion and exclusion criteria from the Leumit healthcare services database between the years 2000 and 2017. Data were collected regarding bDMARD and conventional DMARD consumption, types of malignancies, and their temporal relation to RA diagnosis. The association between baseline variables and occurrence of malignancies was examined by Cox regression. RESULTS: Among 4268 eligible RA patients, 688 (16.12%) were diagnosed with any malignancy. Melanoma skin cancer (MSC) was the most prevalent malignancy (148/688, 21.5%). The proportions out of all malignancies of MSC and non-melanoma skin cancer (NMSC) were higher after than before RA diagnosis (24.7% vs 19.1%, p = .025 and 24.7% vs 13.0%, p = .021, respectively). A higher proportion of RA patients diagnosed with malignancy used bDMARDs in comparison with RA patients who were malignancy-free (40.2% vs 17.5%, p < .001). After adjusting for demographic and clinical variables, bDMARDs were associated with an increased risk of malignancy (hazard ratio 1.42, 95% confidence interval 1.10-1.78). CONCLUSIONS: Biologic DMARDs are associated with increased risk of malignancy among Israeli RA patients, presumably contributed by MSC and NMSC. MSC was the most prevalent type of malignancy in this cohort and may indicate a predisposition state among Israeli RA patients.

Exploring knowledge gaps in the understanding of peripheral and deep en face margin assessment.

In 2022, National Comprehensive Cancer Network updated the phrase of "complete circumferential peripheral and deep margin assessment (CCPDMA)" to "peripheral and deep en face margin assessment (PDEMA)," which was meant to create more consistency across all treatment modalities and provide clarity to the meaning of total margin evaluation. The aim of this project was to investigate the interpretation of PDEMA across pertinent specialties and to identify any existing knowledge gaps in hopes of improving clinical performance of institutional practice. An electronic survey was administered to medical professionals within the divisions of dermatology and otolaryngology retrieving demographic data and assessing respondents' knowledge on tissue processing techniques and PDEMA. Of the four knowledge-based assessment questions administered, dermatology respondents answered three questions with > 80% accuracy and one question with < 65% accuracy. Otolaryngology respondents answered one question with > 80% accuracy and three with < 65% accuracy. Both groups answered the knowledge-based question evaluating the concept of "what must be true for Mohs or PDEMA to have value" with under 65% accuracy. When comparing dermatology and otolaryngology respondents, only one question which evaluated the proper methods to "achieve processing of the epidermal edge and the base of the tumor along a single plane in the lab" significantly differed between groups, with a percentage correct of 96% for dermatologists compared to 54% for otolaryngologists (p < 0.001). Results were found to be similar when resident physicians were removed from analysis. The overall percent correct for knowledge-based questions was shifted higher for dermatologists compared to otolaryngologists (p = 0.014). This trend was also redemonstrated when analyzing the data excluding residents (p = 0.053).

Risk of skin cancers in mycosis fungoides patients receiving PUVA therapy: A real-life experience from a single tertiary center.

BACKGROUND: Mycosis fungoides (MF) is the most common cutaneous T-cell lymphoma. Skin-directed therapies, including phototherapy, are the first-line treatment modalities. Psoralen plus ultraviolet A light photochemotherapy (PUVA) is quite effective in controlling the disease; however, long-term adverse effects, particularly carcinogenesis, are the cons of this treatment. OBJECTIVE: There are various studies on the negative impact of PUVA on skin cancer in patients with autoimmune skin diseases. The data on the long-term effects of phototherapy on MF patients are scarce. METHODS: All MF cases that received PUVA alone or combined with other treatments at a single tertiary center were analyzed. This study compared the development of non-melanoma skin cancers, melanoma, and solid organ tumors in MF patients with at least 5-year follow-up data with age- and sex-matched controls. RESULTS: A total of 104 patients were included in the study. Ninety-two malignancies were detected in 16 (15.4%) patients, and six developed multiple malignancies. Skin cancers consisted of 56 basal cell carcinomas, 16 Bowen's disease, four squamous cell carcinomas, three melanomas, two basosquamous cell carcinomas, one Kaposi sarcoma, and one keratoacanthoma were found in nine (8.7%) patients. Eight patients developed three solid cancers and six lymphomas. The risk of developing skin cancer was associated with the total number of PUVA sessions (<250 vs ≥250 sessions; hazard ratio (HR) 4.44, 95% confidence interval (CI) 1.033-19.068; p = .045). 9 (13.2%) of 68 patients who had follow-ups for at least 5 years developed skin cancer. Compared to an age- and sex-matched cohort, the prevalence of new skin cancer was considerably greater (p = .009). CONCLUSIONS: Patients with MF are predisposed to develop secondary malignancies, and continual exposure to PUVA may potentiate this risk. Annual digital dermoscopic follow-up in MF patients treated with UVA is advised for early diagnosis and treatment of secondary cutaneous malignancies.

Characteristics and Outcomes for Hospitalized Patients With Cutaneous T-Cell Lymphoma.

Importance: Cutaneous T-cell lymphoma (CTCL) is a group of rare, complex cutaneous malignant neoplasms associated with significant disease burden on patients and the health care system. Currently, the population of patients with CTCL admitted to the hospital remains largely uncharacterized and poorly understood. Objective: To characterize the clinical characteristics, course of hospitalization, and mortality outcomes of an inpatient CTCL cohort. Design, Setting, and Participants: This multicenter retrospective cohort study reviewed medical records for adult patients (age ≥18 years) with a CTCL diagnosis per National Comprehensive Cancer Network guidelines admitted for inpatient hospitalization at 5 US academic medical centers with inpatient dermatology consult services and CTCL clinics between August 2016 and August 2020. Main Outcomes and Measures: Patient demographics, clinical history and findings, hospitalization courses, and mortality outcomes. Results: A total of 79 hospitalized patients with CTCL were identified, including 52 (70.3%) men and 22 (29.7%) women, with a median (IQR) age at hospitalization of 62.9 (27-92) years. The majority of admitted patients with CTCL were White (65 patients [82.3%]), had disease classified as mycosis fungoides (48 patients [61.5%]), and had advanced-stage disease (≥IIB, 70 patients [89.7%]). Most hospitalizations were complicated by infection (45 patients [57.0%]) and required intravenous antibiotic therapy (45 patients [57.0%]). In-hospital mortality occurred in 6 patients (7.6%) and was associated with higher body mass index (36.5 vs 25.3), history of thromboembolic disease (50.0% vs 12.3%), and diagnosis of sepsis on admission (66.7% vs 20.5%). At 1-year postdischarge, 36 patients (49.3%) patients had died, and mortality was associated with history of solid organ cancers (27.8% vs 10.8%), wound care as the reason for dermatology consultation (58.3% vs 24.3%), and presence of large cell transformation (58.3% vs 22.9%). Conclusions and Relevance: The findings of this cohort study improve the understanding of hospitalized patients with CTCL and lend valuable insight into identifying factors associated with both in-hospital and long-term mortality outcomes. This refined understanding of the inpatient CTCL population provides a foundation for larger, more robust studies to identify causal risk factors associated with mortality, development of prognostic scoring systems to estimate the probability of hospital mortality. Overall, the findings may prompt physicians caring for patients with CTCL to implement preventive strategies to diminish hospitalization and improve clinical management across this unique disease spectrum.

Primary Cutaneous Lymphoma Registry of the Spanish Academy of Dermatology and Venereology (AEDV): Data for the First 5 Years. / Registro de linfomas cutáneos primarios (RELCP) de la AEDV: datos tras 5 años de funcionamiento.

BACKGROUND AND OBJECTIVE: Primary cutaneous lymphomas (PCL) are uncommon. Observations based on the first year of data from the Spanish Registry of Primary Cutaneous Lymphomas (RELCP, in its Spanish abbreviation) of the Spanish Academy of Dermatology and Venereology (AEDV) were published in February 2018. This report covers RELCP data for the first 5 years. PATIENTS AND METHODS: RELCP data were collected prospectively and included diagnosis, treatments, tests, and the current status of patients. We compiled descriptive statistics of the data registered during the first 5 years. RESULTS: Information on 2020 patients treated at 33 Spanish hospitals had been included in the RELCP by December 2021. Fifty-nine percent of the patients were men; the mean age was 62.2 years. The lymphomas were grouped into 4 large diagnostic categories: mycosis fungoides/Sézary syndrome, 1112 patients (55%); primary B-cell cutaneous lymphoma, 547 patients (27.1%); primary CD30+lymphoproliferative disorders, 222 patients (11%), and other T-cell lymphomas, 116 patients (5.8%). Nearly 75% of the tumors were registered in stage I. After treatment, 43.5% achieved complete remission and 27% were stable at the time of writing. Treatments prescribed were topical corticosteroids (1369 [67.8%]), phototherapy (890 patients [44.1%]), surgery (412 patients [20.4%]), and radiotherapy (384 patients [19%]). CONCLUSION: The characteristics of cutaneous lymphomas in Spain are similar to those reported for other series. The large size of the RELCP registry at 5 years has allowed us to give more precise descriptive statistics than in the first year. This registry facilitates the clinical research of the AEDV's lymphoma interest group, which has already published articles based on the RELCP data.

Sézary syndrome: Report of a rare case with perioral manifestation and review of the literature.

This report aimed to describe a rare case of Sézary syndrome (SS) diagnosed in an Oral Medicine service. A 54-year-old female presented a generalized pruritus and erythema of the skin of 2 years in duration, which had been treated with antihistamines, corticosteroids, and hydrating creams, without resolution. Extra-oral examination showed a painful lymphadenopathy on the right supraclavicular region. Ultrasound-guided fine-needle aspirationbiopsy did not detect any abnormalities. The patient's skin was remarkably dry and thickened, with erythroderma, fissures, and ulcerations. The perioral region exhibited extreme peeling and angular cheilitis. Immunophenotyping of peripheral blood revealed proliferation of undifferentiated T-cells and a massive proportion of TCD4+ cells relative to TCD8+ cells. PET/CT examination demonstrated multiple lymphadenopathies, and bone marrow biopsy was negative for neoplastic cell infiltration. A diagnosis of SS was established, and the patient is currently being treated with UVB phototherapy, methotrexate, doxepin, and folic acid, with mostly complete regression of signs and symptoms.

Primary cutaneous lymphoma patients seen at a referral dermatological centre in 1 year: A single-centre observational retrospective cohort study of the diagnoses and staging, comorbidities and associated symptoms, treatment performed and clinical course.

IMPORTANCE: Primary cutaneous lymphomas (PCL) are rare diseases, but the indolent course makes their prevalence high. Although there are many treatment options, no hierarchy is recommended. OBJECTIVE: To identify the burden of PCL and describe clinical-pathologic features; associated comorbidities; analyse treatment approaches in real-life and the parameters associated with the achievement of complete response (CR). DESIGN, SETTING AND PARTICIPANTS: In this study, all the PCL patients (384 patients) consecutively seen at the Dermatologic Clinic of the University of Turin from January 1, 2019 to December 31, 2019, with follow-up updated to December 2020, were included. MAIN OUTCOMES AND MEASURES: Subtype of PCL, demographic data, time elapsed between first lesions and diagnosis, associated symptoms, comorbidities, staging at diagnosis, high-grade transformation, blood involvement, stage progression, therapies used and response were assessed. RESULTS: 247 were cutaneous T-cell lymphomas (CTCL, 64.3%), 137 cutaneous B-cell lymphomas (CBCL, 35.7%) and the most frequent subtype was MF (48.4%). 62.3% of CTCL patients showed at least one comorbidity, mainly cardiovascular (28.7%), 20.2% show other not cutaneous neoplasms. The main approaches were skin-directed therapies (topical steroids 65.6%; phototherapy 50.2%). 39.3% patients achieved a CR during the disease course. Pruritus, the presence of comorbidities and high-grade transformation were factors associated with failure to achieve CR, whereas stage IA of MF was associated with greater achievement of CR. CONCLUSIONS AND RELEVANCE: The Th2 cytokine related development of pruritus could justify increased resistance to treatment, while the presence of associated comorbidities could reduce treatment options as well as treatment compliance.

Concordance in judgment of clinical borders of basal cell carcinomas in Japanese patients: A preliminary study of JCOG2005 (J-BASE-MARGIN).

Basal cell carcinoma is the most common type of skin cancer, and surgical excision with clear margins is the standard of care. Surgical margins are determined based on risk factors (high or low risk) for recurrence according to the National Comprehensive Cancer Network and Japanese basal cell carcinoma guidelines. The clarity of the clinical tumor border (well-defined or poorly defined) is considered a risk factor, and significant discrepancies in the judgment of clinical tumor borders among dermato-oncologists may occur. Therefore, we analyzed the dermato-oncologists' concordance in judging the clinical tumor border of basal cell carcinoma. Forty-seven dermato-oncologists (experts: 37; young trainees: 10) participated in this study. The datasets of clinical and dermoscopic photographs of 79 Japanese cases of head and neck basal cell carcinoma were used to determine the concordance in the judgment of clinical tumor border. The probability of the border that was selected more often was used to calculate the rater agreement rate for each dataset. Correct judgment was defined as a more frequently selected border, and the concordance rate of clarity of clinical tumor border for each dermato-oncologist was calculated based on the definition of the correct judgment. A median concordance rate of 85% or higher for all dermato-oncologists was predefined as an acceptable rate for clinical use. Of the 79 datasets, rater agreement rates were 80-100%, 60-79%, and 51-59% for 55, 19, and five datasets, respectively. The median concordance rate for all dermato-oncologists was 86% (interquartile range: 82-89%). There was no significant difference in the concordance rate between the experts and the trainees (median, 87% vs. 85.5%; p = 0.58). The concordance rates of dermato-oncologists for all datasets were relatively high and acceptable for clinical use.

Basal cell carcinoma: An updated review of pathogenesis and treatment options.

Basal cell carcinoma (BCC) remains the most common malignancy worldwide. BCC pathogenesis is a result of the interplay between one's environment, genetics, and phenotypic factors. BCC has a low mortality but given its increasing incidence and potential to cause local destruction thus resulting in significant morbidity, it is vital for dermatologists to remain up to date with recent updates in this malignancy's pathogenesis and treatment. This article provides a comprehensive review of the pathogenesis of BCC as well as the current treatments available and clinical trials underway. We also touch upon the updated National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology in respect to BCC's recommended treatment modalities.

Blue rubber bleb nevus syndrome in a Pakistani child: A case report and regional literature review.

Blue rubber bleb nevus syndrome (BRBNS) is a rare disorder in which there is development of multiple venous malformations and haemangiomas in the skin and visceral organs. The lesions mostly involve the skin and gastrointestinal systems but other organs, including the liver, muscles, and the central nervous system, can also be involved. If untreated, affected individuals develop severe anaemia. Most cases are managed with iron supplementation and blood transfusions but some may require surgical resection, endoscopic sclerosis and laser photocoagulation. Here, we present a case of BRBNS in a four-year-old girl with multiple cutaneous lesions, melena and severe anaemia. Review of South Asian literature showed that only two cases (besides ours) have been reported from Pakistan and the rest were from India. This highlights the lack of awareness of BRBNS among physicians in Pakistan and the rest of South Asian countries.
