Squamous cell cancer--31-year epidemiological study in a city of south Brazil.

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.

Adams-Oliver syndrome: a case report.

We report the case of an infant with Adams-Oliver syndrome, a rare disorder characterized by aplasia cutis congenita, defects of the limbs and extremities, and cutis marmorata telangiectatica. Other associated anomalies have been reported, such as facial dysmorphism, heart defects, and disorders of the central nervous system.
