Management and Future Therapeutic Perspectives of Classic Kaposi's Sarcoma: An Evidence-Based Review.

Background: Kaposi sarcoma (KS) is a cutaneous neoplasm of endothelial origin. The causative agent is the human herpes virus-8 (HHV-8) which, combined with an immune system impairment, causes cell proliferation. To date, high-quality evidence and treatment recommendations for the management of KS are confined to the acquired immune deficiency syndrome (AIDS)-related KS, while the clinical approach to the treatment of classic KS (CKS) is based on small retrospective case series and the experience of clinicians in selected referral centers.

Koebner Phenomenon in Kaposi's Sarcoma: A Large Single-Center Case Series and Review of Current Knowledge.

Background: occasional case reports have described the appearance of Kaposi's sarcoma (KS) on previously unaffected skin after incidental or accidental injury, but the association is probably under-reported.

Objectives: to present a large case series of patients suffering from Koebner phenomenon (KP) in KS and describe their main epidemiological, clinical, and therapeutic features.

Methods: we have retrospectively analyzed our clinical and photographic records of 524 patients who had been diagnosed with KS between 2009 and 2021.

Clinical, Dermoscopic, Ultrasonographic, and Histopathologic Correlations in Kaposi's Sarcoma Lesions and Their Differential Diagnoses: A Single-Center Prospective Study.

(1) Background: Kaposi's sarcoma (KS) is an angioproliferative neoplasm typically appearing as angiomatous patches, plaques, and/or nodules on the skin. Dermoscopy and ultrasonography have been suggested as an aid in the diagnosis of KS, but there is little evidence in the literature, especially regarding its possible differential diagnoses. Our aim is to describe and compare the clinical, dermoscopic, and ultrasonographic features of KS and KS-like lesions.

COVID-19 Vaccination in Patients with Classic Kaposi's Sarcoma.

The novel coronavirus disease 2019 (COVID-19) has represented an overwhelming challenge for worldwide health systems. Patients with cancer are considered at higher risk for severe COVID-19 and increased mortality in case of infection. Although data on the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination in patients with cancer are limited, there is enough evidence supporting anti-infective vaccination in general in patients with active cancer, or with history of previous malignancy.

Mucosal Kaposi's sarcoma in HIV-negative patients: a large case series from a single, tertiary referral center in Italy.

Background: Mucosal involvement in HIV-negative Kaposi's sarcoma (KS) is uncommon but has potentially serious repercussions on patient care. Evidence regarding its epidemiology and optimal management is limited. Invasive endoscopic staging at diagnosis and periodically during follow-up is currently recommended by major guidelines.

Iatrogenic Kaposi's sarcoma in myasthenia gravis: learnings from two case reports.

Introduction: Myasthenia gravis (MG) is an autoimmune neuromuscular disease whose treatment encompasses acetylcholinesterase inhibitors, oral steroids, and other immunosuppressants. Kaposi's sarcoma (KS) is a lymphangioproliferative disease associated with human herpesvirus 8 (HHV-8) infection and immunodeficiency or immunosuppression, mainly corticosteroids.

Case Reports: We present two cases of MG patients treated with oral steroids who developed KS.

Diagnosis and treatment of classic and iatrogenic Kaposi's sarcoma: Italian recommendations.

Kaposi's sarcoma (KS) is a lymphangioproliferative disorder associated with Human herpesvirus 8 (HHV8) infection. Four clinical subtypes are recognized: classic, endemic, epidemic (HIV-related) and iatrogenic. KS diagnosis is based on clinical features, histopathological assessment, and HHV8 serology.

Bone involvement in classic Kaposi's sarcoma.

Background: Classic Kaposi's sarcoma (KS) is a rare angioproliferative neoplasm which typically occurs on the skin of the lower limbs of immunocompetent elderly men. Bone involvement in classic KS has been exceptionally reported.

Objectives: To identify patients with classic KS who developed bone involvement based on a retrospective analysis of our departmental database.

Paclitaxel as first- or second-line treatment for HIV-negative Kaposi's sarcoma: a retrospective study of 58 patients.

Paclitaxel has recently been approved for AIDS-related Kaposi's sarcoma (KS) and there is much interest also in HIV-negative KS. To assess the safety and effectiveness of intravenous paclitaxel in the treatment of non-HIV-associated KS. A retrospective database analysis of our departmental database in histologically proven, HIV-negative KS.

Ultrasonographic intraoperative monitoring and follow-up of Kaposi's sarcoma nodules under treatment with intralesional vincristine.

Background: Intralesional vincristine is an effective treatment for Kaposi's sarcoma (KS) nodules on the skin, but there is little evidence of its action through imaging techniques. Ultrasonography can be an adjunctive tool in the diagnosis and management of KS skin lesions, but data in the literature are few.

Materials And Methods: Five patients with classic KS nodules were treated with intralesional vincristine.

Coexistence of Kaposi's sarcoma and psoriasis: is there a hidden relationship?

The relationship between Kaposi's sarcoma (KS) and psoriasis is still controversial. To analyse the association between KS and psoriasis, address the hypothesis of a reciprocal influence between the two conditions relative to clinical presentation and evolution, and consider the best therapeutic approach to be used for the treatment of psoriasis in KS patients in order to avoid the typical induction or worsening of KS during immunosuppression. We retrospectively reviewed clinical records of 37 patients with KS and psoriasis.

Autoimmune bullous diseases in non-HIV Kaposi's sarcoma: a retrospective study in a large cohort of patients.

Background: Kaposi's sarcoma (KS) is a rare endothelial neoplasm caused by the human herpesvirus 8 (HHV-8). Its risk is increased in immunocompromised patients, including those undergoing immunosuppressive therapy for autoimmune bullous diseases. Conversely, HHV-8 infection has been hypothesized to be a triggering factor of bullous diseases, especially pemphigus.

Efficacy of a detergent combined with a moisturizer for the treatment of pruritus associated with xerosis in an elderly population affected by Kaposi's sarcoma.

Background: Xerosis is common among patients with Kaposi's sarcoma (KS). The aim of our study was to evaluate the efficacy of a detergent containing dihydroavenanthramide D 5% combined with a moisturizer containing 1% of menthol for the treatment of chronic pruritus associated with xerosis in elderly KS patients.

Methods: We conducted a prospective, open-label, intra-individual, right/left comparative study.

Toe web intertrigo in Kaposi's sarcoma patients: a microbiological study in a large cohort of patients.

Kaposi 's sarcoma (KS) is a rare multifocal angioproliferative disease associated with human herpes virus 8 (HHV-8) infection, characterized by cutaneous nodules or plaques especially on the lower limbs. Some skin modifications, such as chronic lymphedema, plantar hyperkeratosis and interdigital desquamation, may be associated with consequent impairment of the local immunosurveillance and increased risk of some bacterial or mycotic infections. With the objective of evaluating if bacterial or mycotic infections in KS patients are supported by different microorganisms compared to control patients, we performed an observational retrospective study, comparing positive cultural swabs of interdigital intertrigo of KS patients with positive cultural swabs of interdigital intertrigo of patients admitted to our dermatologic unit during the last 10 years.
