Introduction: Solid organ transplant recipients (SOTRs) are believed to have an increased risk of metastatic cutaneous squamous cell carcinoma (cSCC), but reliable data are lacking regarding the precise incidence and associated risk factors.

Methods: In a prospective cohort study, including 19 specialist dermatology outpatient clinics in 15 countries, patient and tumor characteristics were collected using standardized questionnaires when SOTRs presented with a new cSCC. After a minimum of 2 years of follow-up, relevant data for all SOTRs were collected.

Atypical mycobacterioses are unusual infections of the skin and other organs caused by non-tuberculous mycobacteria. Fish tank granuloma and swimming pool granuloma are two forms of atypical mycobacterioses caused by Mycobacterium marinum. So far, only a few cases of these infections have been reported in organ transplant patients, and these usually are more severe when compared with atypical mycobacterioses in immunocompetent hosts.

Background: Systemic therapeutic management of post-transplant Kaposi sarcoma (KS) is mainly based on 3 axes: reduction of immunosuppression, conversion to mammalian target of rapamycin (mTOR) inhibitors, chemotherapy, or a combination of these.

Objective: To obtain an overview of clinical strategies about the current treatment of KS.

Methods: We conducted a multicenter retrospective cohort study including 145 solid organ transplant recipients diagnosed with KS between 1985 and 2011 to collect data regarding first-line treatment and response at 6 months.

Purpose Transplant recipients who develop cutaneous squamous cell carcinomas are at high risk for multiple subsequent skin cancers. Sirolimus has been shown to reduce the occurrence of secondary skin cancers, but no study included a follow-up exceeding 2 years. We extended at 5 years the TUMORAPA randomized trial of sirolimus-based immunosuppressive regimen versus calcineurin inhibitor-based immunosuppression.

Article Synopsis
  • - The study focuses on how mTOR inhibitors (mTORis) impact the expression of proteins related to the mTOR pathway in cutaneous squamous-cell carcinomas (SCC) in organ-transplant recipients (OTR), who often face skin tumor issues while on immunosuppressants.
  • - Researchers conducted an immunohistochemical analysis on 23 SCC samples, comparing their protein expression patterns before and after the patients switched to mTORis, examining for markers like pAkt, pmTOR, and PI3K.
  • - The findings revealed that switching to mTORis did not lead to significant changes in the expression levels of key proteins (pmTOR, PI3K, pAkt) involved in the mTOR
