RESUMEN
BACKGROUND: Methotrexate (MTX) has been a longstanding therapeutic option for mycosis fungoides (MF); however, data on its real-world effectiveness remain limited. OBJECTIVES: To evaluate treatment-related outcomes of oral MTX in patients with early- and late-stage MF. METHODS: This is a retrospective multicentre analysis involving MF subjects from five referral centres for cutaneous lymphomas in Greece. Data regarding the effectiveness and safety were analysed. RESULTS: In total, 211 MF patients were enrolled (males, 68.3%) with a median (IQR) age of diagnosis at 68.3 (56-75) years. Late-stage (IIB-IVB) disease was present in 124 patients (59.3%). MTX monotherapy was administered to 112 (53.1%) patients, with 99 receiving combination regimens with phototherapy, interferon and retinoids. MTX was used as first-line regimen in 103 (48.9%) cases. An overall response rate (ORR) of 55.5% was observed with 29.9% of patients achieving complete responses. MTX demonstrated greater effectiveness as a first-line treatment compared to subsequent use with no significant differences between monotherapy and combination therapy. The median time to best response was 3.8 months (IQR 2.3-9.9 months). Patients with erythrodermic disease (Stage III) had better ORRs compared to patients with tumour stage disease (Stage II) (61.1% vs. 44.8% respectively). The progression-free survival (PFS) varied according to stage, with a median PFS of 17.1 months for early-stage disease, 5.7 months for Stage IIB disease, 46 months for Stage III and 9.6 months for Stage IV disease (0.7-.). Serious adverse (Grade 3) events leading to treatment discontinuation occurred in 14 (6.7%) cases. All patients received oral MTX once weekly with a median weekly dose of 15 mg/week (7.5-25). CONCLUSION: Our findings support MTX as a viable treatment option for MF, particularly when used in the first-line setting, offering a favourable benefit/risk profile. Response rates are stage-dependent, with erythrodermic patients achieving superior and durable responses.
RESUMEN
BACKGROUND: Although Dermatology is largely considered an outpatient specialty, there is an increasing need for Dermatology input in the acute and inpatient setting. During the COVID-19 pandemic, Dermatology services had to be reorganized to facilitate staff redeployment and minimize the risk of exposure to COVID-19 for patients and staff. This led to an unprecedented increase in teleconsultations aided by clinical images. OBJECTIVES: The main aim of our retrospective study was to analyse the acute Dermatology referrals received in the pre-COVID-19 era and during COVID-19 pandemic. METHODS: We retrospectively analysed acute Dermatology referrals using the acute referral log. RESULTS: We retrospectively analysed 500 and 110 acute Dermatology referrals received in the pre-COVID-19 period and during COVID-19 pandemic, respectively. In the pre-COVID-19 era, consultations were most commonly requested by Oncology/Haemato-Oncology, Emergency Departments and General Practice, while during the COVID-19 pandemic General Practice was the most common source of referrals. A wide variety of dermatological conditions were encountered with the most common been eczematous dermatoses. CONCLUSIONS: Although Dermatology is largely an outpatient-based specialty, this study shows the demand for urgent Dermatology input the care of sick patients with severe skin diseases and in the management of skin problems in patients admitted or receiving treatment for other diseases. Re-organization of Dermatology services during the COVID-19 pandemic resulted in a marked increase in teleconsultations (28% versus 84.5%) and highlighted the importance of complete skin-directed physical examination by the referring clinician as well as procurement of good quality clinical images.

BACKGROUND/OBJECTIVES: The clinical diagnosis of penile intraepithelial neoplasia is challenging. No specific dermoscopic criteria for penile intraepithelial neoplasia have been described in the literature. This study aimed to describe and evaluate the dermoscopic features of penile intraepithelial neoplasia. METHODS: Clinical and dermoscopic images of 11 patients with histopathologically confirmed penile intraepithelial neoplasia were recorded and evaluated. RESULTS: The most frequent dermoscopic features were the presence of structureless areas (100%, structureless pink 72.7%) and vascular structures (81.8%), particularly dotted vessels (72.7%). Other findings included the absence of a pigment network (100%); scale (45.5%); scar-like areas (45.5%); erosions (27.3%); and pigmentation consisting of brown-grey dots and globules (27.3%). CONCLUSIONS: The dermoscopic features that characterise penile intraepithelial neoplasia are structureless pink areas and a prominent vascular pattern (mainly clustered dotted vessels). Dermoscopy is a useful tool that can aid in the diagnosis and surveillance of penile intraepithelial neoplasia.

Primary cutaneous lymphomas (PCLs) are a heterogenous group of non-Hodgkin lymphomas arising in the skin from T- or B-lymphocytes, for which there is limited epidemiological data available. To describe the disease characteristics and estimate annual incidence rates (IRs) and temporal trends of PCLs and their subtypes in Attica, Greece. A retrospective analysis of all PCL patients, diagnosed in Attica's main haemopathology referral centre from 2009 to 2021, was conducted. In total, 1,189 patients were included; 725 males and 464 females (males__females=1.56). The median age at diagnosis was 62 years. The annual IR was 2.2 new cases per 100,000 individuals. Most patients (n=979, 82.3%) were diagnosed with cutaneous T-cell lymphoma (CTCL) with a crude IR of 1.8 new cases per 100,000 person-years. Mycosis fungoides (MF) was the most common subtype (n=817, 68.7%), followed by lymphomatoid papulosis (LyP) (n=59, 5.0%). The crude IR for MF was 1.5 new cases per 100,000 person-years. Cutaneous B-cell lymphomas (CBCLs) accounted for 17.6% (n=210) of all PCLs (IR: 0.4 new cases per 100,000 person-years). PCL, CTCL and MF incidence rates increased from 2009 to 2019, followed by a decrease in 2020-2021. The incidence rate of CBCL increased steadily during the study period. The annual IRs of PCL in Greece were higher than those reported in other studies from Europe, America and Asia. The increase in IRs from 2009 to 2019 may reflect physicians' improved diagnostic efficiency. The COVID-19 pandemic may be the reason for the decline in PCL, CTCL and MF diagnoses from 2020 to 2021.

Merkel cell carcinoma (MCC) of the skin is a rare, aggressive and often fatal neuroendocrine skin cancer. The incidence of MCC has significantly increased in the last decades. Factors that have been associated with the development of MCC include infection with Merkel Cell polyomavirus (MCPyV), ultraviolet exposure, hematologic malignancies and immunosuppression.We present three cases of patients living with HIV who were diagnosed with MCC. HIV cases associated with MCC have been rarely reported and to our knowledge, not yet before in the UK.
