Basal cell carcinoma (BCC) is the most common cancer in humans worldwide. Many highly specific dermoscopic criteria for BCC are well established in the literature. On the contrary, other malignant or benign skin tumors may mimic BCC by exhibiting similar or even the same dermoscopic features and therefore obscuring the diagnosis of BCC in certain situations. We herein report a case of BCC with dermoscopic features of both BCC and desmoplastic trichoepithelioma (DT). We would like to remind of the often neglected differential diagnosis of DT in a lesion with arborizing vessels and otherwise unusual dermoscopic presentation.

Nodular basal cell carcinoma, especially when pigmented, can be in differential diagnosis with nodular melanomas, clinically and dermoscopically. Reflectance confocal microscopy is a relatively new imaging technique that permits to evaluate in vivo skin tumors with a nearly histological resolution. Here, we present four cases of challenging nodular lesions where confocal microscopy was able to clarify the diagnosis.

Abstract The aim of this study was to analyze the dermoscopic features in patients with pathohistologically confirmed basal cell carcinoma (BCC). Our retrospective study included 54 patients with 76 BCCs in total, diagnosed in 2016 and 2017. All lesions were classified into four clinical types: nodular, pigmented, superficial and infiltrative. Digital dermoscopic images were evaluated by three observers. We selected five dermoscopic features for analysis, including: the absence of pigment network, the presence of arborizing vessels, blue-gray globules and ovoid nests, leaf-like areas and ulcerations. In the total of 54 patients, there were 22 females and 32 males. At the moment of establishing the diagnosis, the patients’ age was in the range from 31 to 84 years (median age 67 years). The most frequent clinical type was the nodular type with 28 confirmed diagnoses. Nodular BCC was more frequently localized on the head and neck areas compared to the trunk and limbs (p < 0.01). Dermoscopically, the absence of pigmented network was verified in all cases. Arborizing vessels were present in 71 (93.4%) lesions, blue-gray globules and ovoid nests in 33 (42.1%), ulcerations in 44 (57.9%), and leaf-like areas in 5 (6.6%) lesions. Blue-gray globules and ovoid nests were significantly frequent in pigmented BCC in comparison to other clinical types of BCC (p < 0.01). In conclusion, using dermoscopy, it is entirely possible to make a reliable diagnosis of BCC as well as to differentiate it from others skin tumors.

Background. Trichoblastoma (TB) and basal cell carcinoma (BCC) are 2 different neoplasms composed of basaloid cells and have overlapping histopathological features. We compared the immunoexpression of CD10, T-cell death-associated gene 51 (TDAG51), cytokeratin 20 (CK20), androgen receptor (AR), insulinoma-associated protein 1 (INSM1), and nestin for the differential diagnosis of these tumors. Materials and Methods. We assessed a total of 27 BCC and 27 TB cases, including 4 TB lesions in nevus sebaceous and 3 malignant TB lesions for CD10, TDAG51, CK20, AR, INSM1, and nestin expression. Results. Staining for CK20, TDAG51, INSM1, and stromal CD10 was significantly more common in TB cases than in BCC cases ( P < .001). Epithelial CD10 and AR staining was significantly more common in BCC cases than in TB cases ( P < .001). The difference between the groups for nestin staining was not significant ( P > .05). Stromal CD10 staining was the most sensitive marker (96.3%) and INSM1 the least sensitive (55.6%) marker for TB. TDAG51 showed 100% specificity for TB. A larger number of CK20 positive cells was found in the cases associated with nevus sebaceous than in the other TBs. Conclusion. All the selected markers except nestin were useful for the differential diagnosis between TB and BCC. CD10 and TDAG51 were more useful than the other markers. The use of CK20 could be preferred in nevus sebaceous lesions. INSM1 was less effective in highlighting Merkel cells within the lesion than CK20.
