Abstract

Background: Line‐field confocal optical coherence tomography (LC‐OCT) is an emerging diagnostic tool with imaging depth reaching ~400 μm and a novel three‐dimensional (3D) cube providing cellular resolution. As far as we are aware, there are only a limited number of papers that have reported diagnostic criteria for melanocytic lesions using this technique, and none of them have been multicentric. Objectives: Our aim was to establish the diagnostic criteria for melanocytic lesions using LC‐OCT and identify the most significant architectural and cytologic features associated with malignancy. Methods: A retrospective evaluation of 80 consecutive melanocytic lesions from a prospective multicentric data set spanning three European centres was conducted. We excluded facial, acral and mucosal lesions from the study. Dermoscopic and LC‐OCT images were evaluated by a consensus of four observers. Multivariate logistic regression with backward elimination was employed. Results: The main melanoma diagnostic criteria include detecting >10 pagetoid cells in 3D acquisition, irregular 3D epidermal architecture, disrupted dermoepidermal junction (DEJ) and clefting. Significant risk factors were irregular 3D epidermal architecture, >10 pagetoid cells, dendritic cells at DEJ without underlying inflammation. Novel malignancy criteria in vertical view were DEJ disruption and clefting around atypical melanocyte nests. Exclusive melanoma features were epidermal nests, epidermal consumption, dense dermal nests with atypia. Protective features in the absence of any malignancy indicators were DEJ ring pattern, cobblestone, elongated rete ridges (vertical), well‐defined DEJ and wave pattern (vertical). Conclusions: A series of diagnostic criteria for the identification of melanocytic lesions with LC‐OCT have been established. Validation of these criteria in clinical practice through future studies is essential to further establish their utility. [ABSTRACT FROM AUTHOR]

27. Intérêt de la dermatoscopie×400 interprétée par des non-dermatologues et par un logiciel d’intelligence artificielle pour l’identification de tumeurs pigmentées génitales : étude G 2/IA ×400

Author

Bruet, M., Fakih, A., Ravni, E., Cinotti, E., David-Ferreira, C., Habougit, C., Lima, S., Bourgea, C., Dorado Cortez, C., and Perrot, J.L.

Abstract

Les lésions pigmentées de la muqueuse génitale sont fréquentes ; or leur aspect clinique ou dermatoscopique est parfois déroutant. Des travaux ont montré que la complexité des patrons de dermatoscopie×20 (D×20) pouvait être simplifiée par la microscopie confocale in vivo. L’objectif de ce travail était d’évaluer si la dermatoscopie×400 (D×400), autre technique d’imagerie microscopique, permettait de simplifier l’analyse des images de Dx20 de ces tumeurs pigmentées génitales.

Abstract

Purpose: The aim of this study was to determine whether the alar fascia is a distinct layer of the deep cervical neck fasciae. The present study also aimed to elucidate the anatomical limits of this fascia.Methods: Neck dissections of ten adult cadavers were performed, layer by layer, in the retropharyngeal region, under a powered operating microscope. Detailed dissections revealed the anatomical limits of the deep neck fasciae. Histological descriptions were also performed on large tissue samples collected from three cervical dissections.Results: In the ten dissections, three layers of fascia were identified and dissected in the retropharyngeal region: a visceral fascia, a prevertebral fascia and an alar fascia. The alar fascia appeared like a connecting band derivative of the visceral fascia, between both vascular sheaths. It fused completely with the visceral fascia anteriorly at the level of T2 and with the prevertebral fascia posteriorly at the level of C1. No sagittal connection between the visceral fascia and the prevertebral fascia was identified. The stained histological sections confirmed the presence of the visceral and prevertebral fasciae at the oropharyngeal level, with a third intermediate layer closely connected with the visceral fascia.Conclusion: The alar fascia is a layer of the cervical neck fascia connected with the visceral fascia from C1 to T2 levels. The anatomical limits of this alar fascia and its relationships with the internal carotid artery are important in the surgical management and the prognosis of deep neck infections and retropharyngeal lymph node metastases.

47. Aspect en microscopie confocale par réflectance in vivodes kératoses actiniques

Author

Perrot, J.L., Tognetti, L., Habougit, C., Biron Schneider, A.C., Couzan, C., rubegni, P., and Cinotti, e.

Abstract

Le diagnostic de kératoses actiniques est le plus souvent clinique. Toutefois il est parfois nécessaire de recourir à des méthodes d’imagerie non invasives pour confirmer ce diagnostic. L’examen en microscopie confocale par réflectance d’une kératose actinique peut permettre de constater dans l’épiderme une hyperkératose (cornéocytes détachés, isolés ou en squames), une parakératose (cellules nucléées dans la couche cornée), des kératinocytes atypiques pouvant former un réseau dont les mailles ne sont plus régulières (perte de l’image en nid d’abeille régulier) mais aussi parfois de cellules inflammatoires (exocytose) et une spongiose. Dans le derme on peut mettre en évidence des vaisseaux dilatés et des signes d’élastose solaire : amas de matériel modérément reflétant et/ou des fibres élastiques brillantes ondulées bien visibles dans le derme superficiel. On peut espérer que les nouvelles techniques d’imagerie microscopique in vivonotamment la tomographie par cohérence optique confocale à balayage en ligne permettent d’améliorer encore la pertinence diagnostic du fait d’un examen tridimensionnel de la peau.

Abstract

Background Acral lentiginous melanoma ( ALM) can be difficult to differentiate from acral nevus. Reflectance confocal microscopy ( RCM) is widely used for the diagnosis of melanocytic tumours, but the RCM features of ALM and acral nevus have not been described yet. Objective To determine the RCM features of ALM and acral nevus, and their correlation with clinical and histological characteristics. Methods Retrospective study of 17 cases of ALM and 26 acral nevi. Results Pagetoid cells were present in all ALMs with a visible epidermis and in three nevi. A proliferation of atypical melanocytes at the dermal-epidermal junction ( DEJ) and/or in the dermis was visible in nine ALMs but not in nevi. The histopathological examination of initial skin biopsies was unable to diagnose ALM in four cases, differing from RCM that could identify malignant tumour cells by exploring the whole lesions. Conclusion Reflectance confocal microscopy can help in the differentiation of ALM and acral nevus, and to guide the biopsy. [ABSTRACT FROM AUTHOR]
