Optical Coherence Tomography as a Valuable Tool for the Evaluation of Cutaneous Kaposi Sarcoma Treated with Imiquimod 5% Cream.

Kaposi sarcoma (KS) is a rare disease that was not frequently identified before the widespread occurrence of AIDS. Even today, it remains a challenge for physicians to diagnose, particularly in its early stages, often requiring referral to specialists and further investigations. Dermoscopy, a non-invasive imaging technique, reveals a distinctive rainbow pattern that strongly indicates KS.

Syphilis, the Great Imitator-Clinical and Dermoscopic Features of a Rare Presentation of Secondary Syphilis.

Syphilis is characterized by a wide range of variable clinical symptoms; therefore, it is often referred to as "The Great Imitator". Here, we report the case of a 69-year-old hepatitis-C-positive MSM patient, who was admitted to our clinic due to a solitary firm painless erythematous maculopapular lesion with a central crater-like crust on the upper right thigh that occurred two months prior. The dermoscopy showed an erythematous, copper-colored, oval lesion with diffuse monomorphic dotted and glomerular vessels, central crust, and circular scaling (Biett's sign).

Keratoconus: the possible involvement of inflammatory cytokines in its pathogenesis. An experimental study and review of the literature.

Objective: Keratoconus (KC) is generally described as a non-inflammatory disease, characterized by thinning in the central region of the cornea with consequent tissue degradation producing impaired visual acuity.

Materials And Methods: In our experimental study, we analyzed the presence and implications of several inflammatory cytokines in the corneal tissues of patients suffering from keratoconus by immunohistochemical analysis.

Results: The analysis showed increased levels of inflammatory factors in the pathological tissues compared to controls, confirming that KC cannot be considered an entirely non-inflammatory pathology and that its etiopathogenesis includes several chronic inflammatory events.

Identification of anaplastic lymphoma kinase fusion in clear cell renal carcinoma (ALK-tRCC): a precision oncology medicine case report.

Background: Translocation-associated renal cell carcinoma involving ALK (ALK-tRCC) is a rare subtype of adult renal cell carcinoma (RCC) reported in recent years.

Case Presentation: A new Italian case of ALK-tRCC was reported. The patient was a female 44-year-old with a metastatic and pretreated RCC.

Evaluation of Merkel Cell Polyomavirus DNA in Tissue Samples from Italian Patients with Diagnosis of MCC.

Because the incidence of Merkel cell carcinoma (MCC) has increased significantly during the last 10 years and it is recognized that Merkel cell polyomavirus (MCPyV) and ultraviolet (UV) radiation represent two different etiological inputs sharing clinical, histopathological, and prognostic similar features, although with different prognosis, this study investigated the detection of MCPyV in skin and lymph nodes with histological diagnosis of MCC. Formalin-fixed paraffin-embedded tissue (FFPE) were retrieved from archived specimens and MCPyV non-coding control region (NCCR) and viral capsid protein 1 (VP1) sequences were amplified and sequenced. Results provide an interesting observation concerning the discrepancy between the MCPyV DNA status in primary and metastatic sites: in fact, in all cases in which primary and metastatic lesions were investigated, MCPyV DNA was detected only in the primary lesions.

Acute Cardiovascular Manifestations in 286 Children With Multisystem Inflammatory Syndrome Associated With COVID-19 Infection in Europe.

Background: The aim of the study was to document cardiovascular clinical findings, cardiac imaging, and laboratory markers in children presenting with the novel multisystem inflammatory syndrome associated with coronavirus disease 2019 (COVID-19) infection.

Methods: This real-time internet-based survey has been endorsed by the Association for European Paediatric and Congenital Cardiologists Working Groups for Cardiac Imaging and Cardiovascular Intensive Care. Children 0 to 18 years of age admitted to a hospital between February 1 and June 6, 2020, with a diagnosis of an inflammatory syndrome and acute cardiovascular complications were included.

Presentation, Treatment Response and Short-Term Outcomes in Paediatric Multisystem Inflammatory Syndrome Temporally Associated with SARS-CoV-2 (PIMS-TS).

The novel Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is the pathogen responsible for Coronavirus Disease 2019 (COVID-19). Whilst most children and young people develop mild symptoms, recent reports suggest a novel paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS). Case definition and classification are preliminary, treatment is empiric and disease-associated outcomes are unclear.

Frontal fibrosing alopecia and genital Lichen sclerosus: Single-center experience.

Background: Despite the incidence of Frontal fibrosing alopecia (FFA) has been increasing in last two decades, the pathophysiology and trigger factors of FFA have not been yet fully understood.

Aims: The aim of this study was to describe epidemiology, clinical and trichoscopic features and comorbidities of FFA patients, in order to improve the understanding of this disease.

Patients/methods: A retrospective, observational monocentric study was conducted from 2003 to 2019.

A case of acanthosis nigricans in a HIV-infected patient.

Background: To date, very little information is available concerning the relationship between acanthosis nigricans (AN) and infection with human immunodeficiency virus type 1 (HIV-1).

Case Presentation: Herein, we report the case of a middle-aged man admitted for fever and progressively worsening dyspnea in the context of an opportunistic pneumonia and firstly diagnosed with acquired immunodeficiency syndrome (AIDS). At the time of diagnosis, physical examination revealed the presence of a palpable, hyperpigmented skin lesion on the left areola with surface desquamation and velvety texture consistent with AN.

Eosinophilic folliculitis of the scalp associated with PD-1/PDL1 inhibitors.

Background: Immune checkpoint inhibitors are monoclonal antibodies which target immune "checkpoints" enhancing T cell-mediated cytotoxic and antitumor responses. Together to the amazing results, these drugs are associated with some peculiar adverse events called immune-related adverse events. Alopecia is one of these.

Isoradiotopic response of discoid lupus after radiotherapy: A case report and review of the literature.

Radiotherapy is frequently associated with a great number of collateral effects, which can affect the skin and its appendages. In addition to more common side effects, like radiodermatitis, other cutaneous conditions are less known and often they are underdiagnosed. Among these, isoradiotopic response is one of the rare radiotherapy-associated phenomena.

MiRNAs as Potential Prognostic Biomarkers for Metastasis in Thin and Thick Primary Cutaneous Melanomas.

Background/aim: The identification of novel prognostic biomarkers for melanoma metastasis is essential to improve patient outcomes. To this aim, we characterized miRNA expression profiles in relation to metastasis in melanoma and correlated miRNAs expression with clinical-pathological factors.

Materials And Methods: MiR-145-5p, miR-150-5p, miR-182-5p, miR-203-3p, miR-205-5p and miR-211-5p expression levels were analyzed in primary cutaneous melanomas, including thin and thick melanomas, and in melanoma metastases by quantitative Real-Time PCR.

Scleroderma with an update about clinico-pathological correlation.

Scleroderma is divided into a systemic form called systemic sclerosis and a localized form also called morphea. According to 2013 ACR/EULAR Classification Criteria for Systemic Sclerosis, developed by the American College of Rheumatology (ACR) and the European League Against Rheumatism (EULAR), skin thickening of the fingers extending proximal to the metacarpophalangeal joints is sufficient for a patient to be classified as having scleroderma. Histological examination is not included in the diagnostic criteria and is not routinely performed.

Axillary ectopic lobular carcinoma of breast: two rare case reports.

Objective: The presence of ectopic or supernumerary breast tissue is a rare event, related to a not complete regression of breast tissue along the milk line. Primary ectopic breast cancer of the axilla can create many difficulties in differential diagnosis with subsequent delayed specific treatments. The incidence of ectopic breast tissue is 0.

Clinical, histological, and ultrasound follow-up of breast reconstruction with one-stage muscle-sparing "wrap" technique: A single-center experience.

Background: Prepectoral implant placement and complete coverage with porcine acellular matrix after mastectomy is a new concept in breast surgery presented in few cases in the literature. This paper aimed to present our single-center experience in one-stage breast reconstruction muscle-sparing "wrap" technique by evaluating clinical and aesthetic outcomes, ultrasound and histological examination, and patient quality of life.

Methods: From January 2014 to January 2017, 52 patients (40 unilateral, 12 bilateral) underwent one-stage muscle-sparing breast reconstructions with Braxon acellular dermal matrix and implant.

Plaque-Like Myofibroblastic Tumor of Infancy: A New Case Report and Literature Review.

Plaque-like myofibroblastic tumor of infancy is a rare entity, with only a few reports described in the literature. Herein we present a new case of a nodular plaque-like lesion of the left lower back in an 18-month-old boy. The lesion might initially be thought to be a dermatofibroma, but the overall characteristics suggested the diagnosis of plaque-like myofibroblastic tumor of infancy.

Agminated Blue Nevus: Two Case Reports and a Mini-review of the Literature.

Agminated blue nevus (ABN) is a melanocytic nevus rarely mentioned in the literature and not well known. The term agminated is used when many blue nevi are clustered together in a sharply demarcated area ≤10 cm. Specific dermatoscopic features have not currently been clearly defined.

Extracorporeal Shock Wave Therapy: An Emerging Treatment Modality for Retracting Scars of the Hands.

Prolonged and abnormal scarring after trauma, burns and surgical procedures often results in a pathologic scar. We evaluated the efficacy of unfocused shock wave treatment, alone or in combination with manual therapy, on retracting scars on the hands. Scar appearance was assessed by means of the modified Vancouver Scar Scale; functional hand mobility was evaluated using a range-of-motion scale, whereas a visual analogue score was implemented for detecting any improvements in referred pain.

A very rare case of adult-type granulosa cell tumor.

Granulosa cell tumor (GST) of the testis is a rare neoplasm. Here we describe a case of an adult type GST. More than a year after surgical treatment, without any other treatment, the patient is alive without sign of disease.
