BACKGROUNDMelanoma is one of the conditions with greater increase in incidence worldwide in recent decades. It is a skin cancer with potential high lethality and predominates in Caucasian adults. Treatment of primary cutaneous melanoma is essentially surgical and search for sentinel lymph node can modify the aggressiveness of the treatment.OBJECTIVETo analyze the epidemiological profile of patients diagnosed with primary cutaneous melanoma, histopathological features and compare with literature data.METHODSThis is a retrospective, observational, single-center, case series study of patients with primary cutaneous melanoma, who underwent surgery between January 2008 and December 2013. The parameters include: Age, sex, clinical stage, date of surgery, tumor location, histological subtype, condition of surgical margins, Breslow thickness, mitotic index, presence of ulceration and metastasis on admission.RESULTSWe included 321 melanoma patients who were treated at Hospital Erasto Gaertner. The population consisted of 58.9% females and 41.1% males with an average age of 52.8 ± 16.3 years. As for the clinical stage, 51.1% were in the initial stage, 24.3% in the clinical stage II (A, B and C), 21.2% in clinical stage III and 3.4% with distant metastases. The most frequent location of the primary melanoma was the trunk, and the histological subtype was superficial spreading pattern. Intermediate and thick melanomas were the most frequent.STUDY LIMITATIONSThis is a retrospective study and some information and data could be incomplete or absent.CONCLUSIONThe diagnosis and treatment of melanoma in early stages provides less morbidity and improved survival of patients. Understanding the biological behavior of tumor and knowing the local epidemiology guide health strategies.

Wilms Tumor (WT) is an extremely rare neoplasia in adults. It represents 95% and 1% of all renal tumors, in adults and children respectively. Clinical symptoms are also distinct between adults and children. In adults, symptoms are usually abdominal pain and hematuria, on the other hand, pediatric patients frequently present with an asymptomatic abdominal mass. The recommended treatment for WT in adults follows protocols established for pediatric patients. Currently, the 5-year overall survival rate for adults with WT is of approximately 90%. The adoption of multimodal therapy systematized, and proposed by current protocols, allowed the results to become much more robust, with a significant improvement from less than 30% to 90%. However, recent reviews suggest a worse outcome for adults when compared to children, even when submitted to the same treatment regimen, and comparable according to histology and tumor stage.We present a case of a 26 years-old male patient, who underwent surgery to treat a solid renal mass. Pathological report demonstrated a Wilms tumor. The patiente also received adjuvant chemotherapy with dactinomycin and vincristine. After 12 months follow-up, patient has no evidence of disease.
