OBJECTIVES: The purpose of this study is to evaluate our experience with scalp tumours regarding clinical and epidemiological data, at the Plastic Surgery and Head and Neck Services of the Hospital Oncologico “Padre Machado”. These neoplasms can be either primary or secondary malignancies. METHODS: We carried out a retrospective study, analyzing the medical charts of the patients with a diagnosis of malignant scalp tumours admitted to o from 1993 to 1999. Sex, histologic type, tumour size, location, resective procedure, reconstructive methods, complications and locorregional recurrence were registered. RESULTS: We analyzed a total of 70 medical charts of patients with malignant scalp tumours. 42 were male and 28 female. The most frequent tumour locations were parietal (21.4 %), parietoccipital (15.7 %), frontal (11.4 %) and occipital (11.4 %). Epidermoid carcinoma was diagnosed in 28.6 % of cases. Basaloid carcinoma in 24.3 % and metastatic tumours were found in 20 % of cases. 51.4 % of these patients were treated with wide local excision; 11.4 % required bone resection. The only complications registered were facial paralysis (one patient) and bone exposure in other. Local failure was reported in patients with basaloid cell carcinoma. CONCLUSION: Malignant scalp tumours are mostly epidermoid and basal cell carcinomas. Metastatic lesion must always be considered. A previous biopsy is crucial for ruling out this diagnosis and plan further treatment.
