    Skin lesions in organ transplant recipients: a study of 177 consecutive Brazilian patients
    (2019) OLIVEIRA, Walmar R. P.; TIRICO, Maria C. C. P.; SOUZA, Anaisa A. V.; CODARIN, Felipe R.; SILVA, Lana L. C.; NETO, Cyro Festa
    Background Skin lesions are very common among organ transplant recipients (OTR), particularly infections and tumors, because of the immunosuppressive state these patients are put in. Methods 177 OTR were examined. Skin lesions were categorized into neoplastic, infectious, and inflammatory diseases. Results The mean age of OTR was 52 years, the mean age at transplantation was 42.7 years, and kidney was the most common organ transplanted (72%). Skin lesions were found in 147 patients (83%). Cutaneous infections were seen in 106 patients (60%). Warts (30%) had the larger incidence and were associated with azathioprine (P = 0.026), cyclosporine (P = 0.006), and tacrolimus (P = 0.009). Superficial mycoses occurred in 16% of OTR, mostly onychomycosis, which was associated with tacrolimus (P = 0.040). Actinic keratosis (AK) occurred in 31% of patients and cutaneous tumors in 56%. Squamous cell carcinoma (SCC) was the most common tumor type affecting 36% of OTR (n = 64), with invasive SCC predominating over in situ SCC, whereas basal cell carcinoma (BCC) accounted for 17%. Both SCC and BCC were more numerous in patients' skin type I (P < 0.05). SCC was more frequent (36%) in combined kidney and liver recipients (P = 0.004), and BCC was associated with cyclosporine (P = 0.047). Inflammatory complications (acne, alopecia, hypertrichosis, and gingival overgrowth) were observed in 17.5% of patients. Conclusions Organ transplant recipients must be regularly evaluated by dermatologists, who should be alert to the onset of infections and skin (pre)malignant diseases in these patients.

    Somatic mutations in kinetochore gene KNSTRN are associated with basal proliferating actinic keratoses and cutaneous squamous cell carcinoma
    (2019) SCHMITZ, L.; GRINBLAT, B.; NOVAK, B.; HOEH, A. -K.; HAENDSCHKE, K.; DOBBELER, C. von; BIERHOFF, E.; SZEIMIES, R. -M.; GAMBICHLER, T.; TOREZAN, L.; FESTA-NETO, C.; STOCKFLETH, E.; DIRSCHKA, T.
    Background Mutations in kinetochore gene KNSTRN accelerate the development of cutaneous squamous cell carcinoma (SCC) and may correlate with different histological classifications of actinic keratosis (AKs). Objective To determine KNSTRN gene mutation frequency in healthy skin (HS), actinically damaged skin (ADS), in AKs with different histomorphological gradings and invasive SCCs. Methods All samples were histologically evaluated. AK lesions were additionally classified according to their upwards (AK I-III) and downwards (PRO I-III) directed growth pattern. Mutation analyses of all samples were performed using the Sanger method. Results With one exception, all detected mutations in KNSTRN gene showed an alanine-to-glutamate substitution at codon 40 (p.Ala40Glu). p.Ala40Glu mutation was found in 6.9% (2/29) of HS, in 16.1% (5/31) of ADS, in 18.3% (20/109) of AKs and in 30.0% (9/30) of invasive SCCs. Further stratification of AKs using the common AK classification of Rowert-Huber revealed the p.Ala40Glu mutation in 14.7% (5/43), 13.3% (4/30) and 24.4% (11/45) (AK I, II and III). In contrast, the new PRO classification showed a distribution of 3.6% (1/28) in PRO I, 21.7% (13/60) in PRO II and 28.6% (6/21) in PRO III. Mutation frequency in HS showed significant differences compared to AKs classified as PRO III and invasive SCCs (P < 0.05). In contrast, there were no statistically significant differences between HS and AKs when classified according to Rowert-Huber. Conclusions Recurrent somatic mutation p.Ala40Glu in KNSTRN gene is associated with basal proliferating AKs in accordance with invasive SCCs. This supports the impact of basal proliferative pattern in terms of progression.

    The first observation of the association of Merkel cell polyomavirus and Merkel cell carcinoma in Brazil
    (2019) FESTA NETO, Cyro; OLIVEIRA, Walmar R. P.; COSTA, Pedro V. A.; CARDOSO, Melina K.; BARRETO, Paula G.; ROMANO, Camila M.; URBANO, Paulo R.
    BackgroundMerkel cell carcinoma (MCC) is a rare but aggressive primary cutaneous carcinoma with high mortality rates. The present study intends to delineate the epidemiological profile of patients with MCC seen at the Clinics Hospital of the Medical School at the University of SAo Paulo, Brazil, and its association with Merkel cell polyomavirus (MCPyV). MethodsThis is a retrospective study. A search was performed in the hospital's medical index for all cases of MCC from January 1994 to December 2012. Among patients with MCC, the available tumoral skin specimens were analyzed with two different techniques of polymerase chain reaction (PCR) (conventional and real-time) for detection of MCPyV DNA. Additionally, paraffin-embedded samples of patients with non-MCC skin cancers were also analyzed. Analyses suitable for categorical data (i.e., x(2) of Fisher) were used to compare the proportion of patients in each group. ResultsNineteen patients with MCC and 20 patients with non-MCC skin cancers entered the study. All MCC samples available (13) tested positive for the presence of MCPyV DNA; however, in the non-MCC skin cancer samples, the MCPyV DNA was detected in 4 of 20 samples (20%). MCPyV DNA detection rate was higher in patients with MCC than in the other group, and its analysis was statistically significant (P<0.01). ConclusionsThis study demonstrates the association of MCPyV in Brazilian patients with MCC. However, further studies are necessary to determine the exact involvement of MCPyV in MCC pathogenesis and to define the significance of viral DNA detection in non-MCC skin cancers.
