“…Two of our cases (3.4%) were hidradenomas and showed a pattern composed of a symmetric total large blue ovoid nest, arborizing telangiectasias and whitish structures. The bluish colour associated with hidrocystomas and hidradenomas may be explained by the Tyndall effect, given both the cystic nature and dermal localization of the tumours . According to the results of our study, a pigmented nodule arising in a naevus sebaceous with a total blue large ovoid nest on dermoscopy could be a trichoblastoma, basal cell carcinoma, hidrocystoma or hidradenoma (Fig.…”

“…Blue-colored structures were also present in blue nevi, Spitz nevus, cutaneous melanoma metastases and in adnexal tumors such as ectopic hidradenoma papilliferum (homogeneous bluish pigmentation) [9,10], basal cell carcinomas (blue ovoid nests or blue globules), or in vascular neoplasms (red-blue lacunae) (fig. 6).…”

The Blue Globular Pattern in Dermoscopy

Background: Seborrheic keratosis (SK) is a frequent benign epithelial skin tumor. Generally its diagnosis is clinical, however SK can sometimes clinically simulate a melanocytic lesion; therefore we need dermoscopy to reach a correct diagnosis. Milia-like cysts and comedo-like openings are the common dermoscopic features of SK, but it is not a rare finding that SK can display one or more dermoscopic patterns suggestive of a melanocytic origin. Objectives: We describe a case series of SKs with a blue globular pattern simulating a melanocytic lesion. Methods: We retrospectively evaluated 224 SKs seen during 2011 at the Dermatoscopy Unit of the Department of Dermatology, University of Rome ‘Sapienza'. Results: Five SKs showed a blue globular pattern, without the SK main features generally seen in dermoscopy; globules were multiple, round or oval, well-demarcated, small and medium-sized, blue-colored and equally distributed within the lesion. Histopathologic examination was consistent with acanthotic SK. Conclusions: Identification of the blue globular pattern can be helpful for the dermoscopic diagnosis of SK, especially when its common dermoscopic features are absent.

“…Trichilemmal cysts may show a erythematous periphery, besides the homogeneous blue pattern [ 2 ]. Ectopic hidradenoma papilliferum may present large vessels in the periphery [ 3 ]. Eccrine acrospiroma is surrounded by a discrete pigment network [ 4 ], like some dermatofibromas [ 5 ].…”
