Background: Organ transplant recipients (OTRs) have a very high risk of developing cutaneous squamous cell carcinoma (cSCC).Immunosuppressed OTRs may have a higher proportion of poorly differentiated cSCC than non-OTRs.Objectives: The aim of this study was to investigate the degree of differentiation of cSCCs in OTRs compared with immunocompetent individuals.Patients/Methods: Data from the Swedish Cancer Registry were crosschecked with data from the Transplant registry of the Transplant Institute at Sahlgrenska University Hospital in Gothenburg, Sweden.

All OTRs with Whitening Oral Care a diagnosis of cSCC, basosquamous carcinoma, and/or cSCC in situ established at the Department of Dermatology, Sahlgrenska University Hospital, during 2002-2015 were included.The control group consisted of non-OTRs with the same diagnoses during the same time period.Results: During 2002-2015, 82 OTRs diagnosed with 515 tumors and 883 non-OTRs with 1,247 tumors were included.OTRs developed 0.

47 tumors/year vs 0.10 tumors/year for non-OTRs, but no significant differences were observed in the degree Audio Video Lead of tumor differentiation of invasive cSCCs between OTRs and non-OTRs (P = 0.4).The distribution of poorly, moderately, and well-differentiated invasive cSCCs among OTRs and non-OTRs were 8.

5% vs 12.5%, 22.1% vs 29.9%, and 69.

4% vs 57.6%, respectively.Conclusions: OTRs do not develop a higher proportion of poorly differentiated cSCCs than non-OTRs.
