XXXX of the face and scalp, prognosis and treatment.

72 @entity1 with @entity5426 ( @entity5426 ) of the face and scalp have been analyzed with respect of various prognostic factors and the effects of different treatment regimes. This disease predominantly occurs in the elderly (age range, 56-92 years), and affects @entity1 rather more frequently than @entity1 ( @entity1 : 44, @entity1 : 28). The clinical presentation varied, and included @entity75 , dusky plaques, chronic @entity4 or @entity2688 , ulcerated nodules, @entity6793 , and infected conditions. Due to lack of clinical awareness and problems with histologic assessment, delays in diagnosis were frequent. The majority of the @entity5 arose in the upper part of the face or scalp. Less commonly, the central part of the face was affected while only three @entity5 developed in the mandibular region. Overall the prognosis was poor; one half of the @entity1 died within 15 months of presentation. Only 12% of the @entity1 survived 5 years or more. @entity1 with lesions that were less than 10 cm in diameter responded better to treatment and statistically survived longer than those with larger lesions, emphasizing the crucial importance of early diagnosis. There is some indication that @entity1 , younger @entity1 , @entity1 with lesions on the central part of the face survived longer, but this was not of statistical significance. The histologic differentiation of the @entity5 at presentation also was of doubtful prognostic significance. Despite the overall poor prognosis, radical radiotherapy (mostly wide-field electron-beam therapy) in seven @entity1 resulted in the apparent eradication of the @entity272 and prolonged survival of the @entity1 . Pulmonary metastases developed 10 years later in two of those @entity1 , however, but the face and scalp remained @entity5 -free.
