“…Blue naevus often provides diagnostic difficulties due to its blue coloration, which is also characteristic of melanoma or its metastases, furthermore a dermatoscopic examination does not always allow for differentiation of these lesions [18–20]. Thus, the use of HFUS appears to be of particular interest in the diagnostics of blue naevi.…”

IntroductionUltrasonographic examination is commonly used in an outpatient setting, possibly due to its low cost, low risk for patients and the possibility to obtain real time images. Typically used heads have the frequency ranging from 7.5 to 12 MHz. Higher frequencies ensure higher resolution, yet they are limited by the penetration depth – reaching from several to several tens of millimetres into the skin. High-frequency ultrasonography (HFUS) appears to be a promising method for the detection and differential diagnostics of selected nodular skin lesions.AimThe study aimed at a comparison of the data obtained by using HFUS, histopathological and dermatoscopic images of selected skin lesions to determine their common features.Material and methodsNodular lesions classified as potentially malignant were subjected to clinical, dermatoscopic and high-frequency ultrasonographic examinations. Then the patients were referred for surgical removal with histopathological assessment.ResultsA total of 54 nodular lesions were examined, out of which 34 were diagnosed as non-melanoma. The most common lesions were melanocytic naevi dermatofibroma, nodular basal cell carcinoma and pyogenic granuloma. Other examined lesions included blue naevus, seborrheic wart, xanthogranuloma juvenile and Spits naevus. In all lesions except Spitz naevus, HFUS images corresponded at least with dermatoscopic or histopathology images.ConclusionsHFUS can be used as a supporting diagnostic tool ensuring better pre-operative proceedings. HFUS is a non-invasive, easy and inexpensive screening method for the determination of different skin cancers as it provides valuable information allowing to determine the cutting margins and lesion shape.

“…Besides the above-mentioned studies, there are several case reports in the literature describing BN with peripheral streaks [18,19]. According to Sakamoto et al [18], their presence correlates with the distribution of focally aggregated and isolated spindle cells with melanin in the upper dermis visible in histopathological assessment. Another finding to be considered are pigmented networks, which seem to be a rare observation in BN.…”

Background: Little is known about the correlation between lesion- and patient-related variables and the dermoscopic features of blue nevi. The aim of the study was dermoscopic analysis of blue nevi in association with patient- and lesion-related variables, with a special interest in structures whose prevalence has not been previously reported. Methods: This was a double-center, retrospective study, which included the analysis of histopathologically confirmed blue nevi (n = 93). Results: There was no difference in the frequency of the observed dermoscopic features according to patients’ gender and age. Pink structureless areas were more common in patients with I/II Fitzpatrick skin phototypes as well as in the patients with photodamaged skin, while blue prominent skin markings over brownish/blue-gray background occurred exclusively in patients with phototype III. Structures of previously unreported prevalence in blue nevi were skin-colored circles (present in 32.3%), gray circles (2.2%), follicular ostia with no pigmentation (18.4%; present exclusively on the face), blue skin markings over brownish background (present in 18.2%; detected only on the limbs) and dark brown polygons (one lesion located on the lower extremity). Conclusion: Dermoscopic presentation of blue nevi may vary according to the patient’s phototype and lesion size/localization rather than gender and age.

“…Under dermatoscope, MBN may also exhibit fragmented bluish reticular-like formations at the periphery (histopathologically corresponding to the presence of free melanin and melanophages in the papillary dermis) [17], as it was the case in our patient. However, on rare occasions benign blue nevi may also display certain "atypical" dermatoscopic features, such as peripheral streaks with branches or satellitosis [18,19]. Therefore, in some cases it is impossible to distinguish between benign blue nevus and MBN with clinical and dermatoscopical evaluation.…”

Malignant blue nevus is a term related to melanoma arising in association with or that resembles blue nevus. Such lesions are extremely rare with occasional reports and a few small series of cases described in the literature; therefore, the biology and prognosis of such tumors is not well clarified. Due to lack of strictly defined histopathological criteria, such lesions may present a significant diagnostic challenge. We are presenting a case of a malignant blue nevus arising in a congenital cellular blue nevus, presenting as a slowly progressing and asymptomatic pigmented lesion on the buttock of a 21-year-old woman. Histopathological analysis showed presence of a cellular blue nevus as well as features characteristic for malignant blue nevus. The definitive diagnosis was reached only at the histopathological and immunohistochemical examination. The histological features and clinical course in our patient are also discussed in context and the review of the previous related literature.
