Clinical diagnostic accuracy of basal cell carcinoma

Basal Cell Carcinoma (BCC) incidence is 75% of all skin cancers. BCC rarely causing mortality, but morbidity is high. Clinical diagnostic is the early detection of BCC suspicion, therefore, we required specific criteria that help to establish the clinical diagnosis. The objective of this study was to know the clinical sign as a predictor of basal cell carcinoma. Ten patients with skin tumors who came to dermatovenereological department of Dr. Moewardi hospital were included in this study. Clinical diagnosis using clinical criteria from keratinocyte carcinoma in A Cancer Journal For Clinicians in 2011 (Teleangiectasion, raise border, erythematous with bleeding, pigmentation, translucent appearance, and scarlike appearance) was used as reference of clinical diagnostic criteria. Histopathological examination was performed as a gold standard. All 10 subjects had histopathological finding consistent to BCC. The clinical examination like pigmentation were found in all subjects while teleangiectasia, raise border, erythema with bleeding were found on 9 subject. Translucent appearance was found on 6 subjects. While scarlike appearance was absent in all subjects. The criteria from keratinocyte carcinoma in A Cancer Journal For Clinicians in 2011 can be used to diagnosed BCC clinicallyKeywords : Basal cell carcinoma, Clinical Diagnostic Criteria

Background: Preoperative diagnosis of malignant collision tumors (MCT) is extremely difficult. The value of dermoscopy to improve the correct detection of these tumors has not been previously studied. This study aims to evaluate the diagnostic accuracy of MCT with and without dermoscopy and to describe the dermoscopic features of a large series of MCT. Methods: Dermoscopic images of 161 MCT were evaluated. Clinical and dermoscopic images of histopathologically proven MCT intermingled with other tumors were randomly presented to clinicians with different levels of experience, blinded to the diagnosis and objective of the study. The clinical and dermoscopic diagnostic accuracies were measured separately. Results: A total of 161 histopathologically proven cases of MCT were collected. The most frequent MCT was basal cell carcinoma-seborrheic keratosis collision tumor (CT; 37.9%), followed by basal cell carcinoma-melanocytic nevus CT (19.9%), and melanoma-seborrheic keratosis CT (6.8%). Diagnostic accuracy among experts on dermoscopy was 71.4%. The study included 119 participants. The percentage of correct diagnoses was 8% by naked eye examination and 36.4% by dermoscopy (p < 0.001). The presence of the malignant component in the cases of MCT was not recognizable in 19.1% of cases by naked eye examination and in 11.8% of cases by dermoscopy (p < 0.001). Conclusions: The diagnosis of MCT can be assisted and clarified by dermoscopy. However, many of these lesions manifest complex morphologies and continue to be challenging, even for experts on dermoscopy. Atypical, uncertain, or non-classifiable lesions still need a complete excision for the final diagnosis.
