Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), in combination, are referred to as nonmelanoma skin cancers (NMSCs). NMSC is not as extensively studied in the Asian population as it is in the Caucasian population.
This study sought to evaluate the clinical and histopathologic aspects of NMSC from cases of cutaneous malignancies.
The present study is a descriptive analysis of NMSC specimens seen at Department of Pathology, SSIMS and RC, Davangere. Histologically diagnosed NMSC, i.e. BCC and SCC specimens from January 2005 to December 2009 were analyzed according to site distribution, risk factors and histological variants.
Of the various specimens received during the 5year study period, 60 were histologically categorized as skin malignancies, of which 31(51.6%) cases were of NMSC. SCC was the most common NMSC constituting 26 (83.9%) cases and 5 NMSC cases (16.1%) were of BCC. The most common incidence was among the age group 60-80 years (80%) for BCC and 40-60 years (50%) for SCC. Head and neck was the most common site of presentation with predilection for face. Forty-six percent of SCC was histologically categorized as well differentiated, 42.3% as moderately differentiated and 11.5% as poorly differentiated. Most common histological variant of BCC was solid (nodular) type.
NMSC often associated with greater morbidity, necessitating increased efforts to assess risk factors in individuals, to encourage periodic self-examination and professional evaluation of skin and to optimize strategies for earlier diagnosis and treatment.
基底细胞癌(BCC)和鳞状细胞癌(SCC)统称为非黑色素瘤皮肤癌(NMSC)。在亚洲人群中对NMSC的研究不如在白种人群中广泛。
本研究旨在评估皮肤恶性肿瘤病例中NMSC的临床和组织病理学特征。
本研究是对在达万盖雷市SSIMS和RC病理科所见的NMSC标本进行的描述性分析。对2005年1月至2009年12月组织学诊断为NMSC的标本,即BCC和SCC标本,根据部位分布、危险因素和组织学亚型进行分析。
在5年研究期间收到的各种标本中,60例经组织学分类为皮肤恶性肿瘤,其中31例(51.6%)为NMSC。SCC是最常见的NMSC,占26例(83.9%),5例(16.1%)NMSC为BCC。BCC最常见的发病年龄组为60 - 80岁(80%),SCC为40 - 60岁(50%)。头颈部是最常见的发病部位,以面部为主。46%的SCC在组织学上分类为高分化,42.3%为中分化,11.5%为低分化。BCC最常见的组织学亚型是实体(结节)型。
NMSC常伴有较高的发病率,因此有必要加大力度评估个体的危险因素,鼓励定期自我检查和专业的皮肤评估,并优化早期诊断和治疗策略。
