BACKGROUND: The incidence and morbidity of squamous cell cancers are increasing worldwide. Epidemiological studies with morbidity coefficients about this type of cancer are scarce in Brazil. OBJECTIVES: To determine morbidity coefficients, analyze and classify the squamous cell cancers diagnosed in the city of Blumenau - SC from 1980 to 2011, according to clinical and histological features. METHODS: The authors revised 4000 histopathological exams with respect to sex, age, anatomic site and histological type. The morbidity coefficients were calculated using the number of squamous cell cancers found and the annual population estimated by the Brazilian Institute of Geography and Statistics between 1980 and 2011. RESULTS: A total of 4000 tumors were identified, 2249 (56.2%) in male and 1751 (43.8%) in female patients. The standard incidence rates varied from 40 cases in 1980 to 120 cases/100,000 inhabitants in 2011. The morbidity above 70 years of age reached 1484 cases/100,000 inhabitants in male and 975 in female patients. As to primary anatomic site, we found more tumors on the lips and ears in male and on the face and legs in female patients. As to the degree of involvement, the more frequent were Well Differentiated Squamous cell carcinomas (70%) and Moderate Squamous cell carcinomas (19,1%). The Low Differentiated Squamous cell carcinomas, which represented those with the worst prognosis, were found in 4.5% of the tumors. CONCLUSION: Squamous cell cancers in Blumenau - SC have similar patterns of distribution regarding age, primary anatomic site and histological types as found in the international literature. The morbidity increased by 300% in the last 31 years, which indicates that we need to dedicate special attention to the older population.
The basal cell carcinoma is the most common skin cancer but the giant vegetating basal cell carcinoma reaches less than 0.5 % of all basal cell carcinoma types. The Giant BCC, defined as a lesion with more than 5 cm at its largest diameter, is a rare form of BCC and commonly occurs on the trunk. This patient, male, 42 years old presents a Giant Basal Cell Carcinoma which reaches 180 cm2 on the right shoulder and was negligent in looking for treatment. Surgical treatment was performed and no signs of dissemination or local recurrence have been detected after follow up of five years.
O carcinoma basocelular é o tipo mais comum de câncer de pele, mas o carcinoma basocelular gigante vegetante não atinge 0,5% de todos os tipos de carcinomas basocelulares. O Carcinoma Basocelular Gigante, definido como lesão maior que 5 cm no maior diâmetro, é uma forma rara de carcinoma basocelular e comumente ocorre no tronco. Este paciente apresenta um Carcinoma Basocelular Gigante com 180cm² no ombro direito e foi negligente em procurar tratamento. Foi realizado tratamento cirúrgico e nenhum sinal de disseminação ou recorrência local foi detectada após 5 anos.
The authors report a primary cutaneous cryptococcosis, caused by Cryptococcus neoformans in immunocompetent patient, a farmer who developed extensive lesions at the site of an injury caused by one of the chickens on his right forearm, while he was cleaning out his barn. Oral treatment with fluconazole was totally successful. A review of the literature showed the rarity of cutaneous cryptococcosis in immunocompetent patients and in contrast, that skin lesions frequently occur in immunocompromised patients.
Os autores relatam caso de Criptococcose cutânea primária, causada pelo Cryptococcus neoformans, em paciente imunocompetente, fazendeiro que desenvolveu extensivas lesões, no antebraço, após injúria provocada por galináceo, quando fazia limpeza de seu celeiro. Tratamento oral com fluconazol resultou em cura total. A literatura relata raridade de criptococcose cutânea primária em imunocompetentes e sua relativa frequência em imunodeprimidos.
