WEBER, Ariana Lebsa; NUNES, Daniel Holthausen; SOUZA FILHO, Jorge José de  and  PINTO, Carlos José de Carvalho. A comparison of cutaneous melanoma cases diagnosed by different medical specialists. An. Bras. Dermatol. [online]. 2007, vol.82, n.4, pp. 311-315. ISSN 1806-4841.  http://dx.doi.org/10.1590/S0365-05962007000400003.

BACKGROUND: Early diagnosis and intervention in melanoma cases are crucial for prognosis. OBJECTIVE: To compare the results of cutaneous melanoma cases diagnosed by different medical specialists, in the city of Florianopolis, Brazil. METHOD: A total of 396 reports of 332 patients with histopathological diagnosis of melanoma were analyzed. The reports were collected from two laboratories in Florianopolis from January 1st, 1999 to December 31st, 2004. The protocol was based on the questionnaire of the Brazilian Group of Melanoma, including sex, age, lesion site, medical specialty that ordered the exam and tumor thickness (Breslow index). RESULTS: Our findings showed 186 melanomas in situ and 210 invasive melanomas, predominantly in females (56%). The incidence peak was between the 5th and 6th decades of life. Breslow index was similar in both male and female groups (p = 0.424). The mean Breslow index was 1.852mm for dermatology and 4.383mm for other medical specialties (p = 0.037). A higher number of ulceration was found in the group diagnosed by general surgeons (p = 0.05). Dermatologists diagnosed 217 (54%) cutaneous melanomas from the sample and most clinical histological types, except for the acral type. CONCLUSION: The role played by dermatologists is essential for early diagnosis of cutaneous melanoma, therefore changing its outcome.
