Metastatic spread to the salivary glands is rare, occurring primarily from head and neck tumors to the parotid gland. So far, only one sublingual gland metastasis has been reported in the literature. We herein report the second case of metastasis to this gland occurring in a woman in her 50s, previously diagnosed with HER2-positive metaplastic breast carcinoma (MpBC) with chondroid differentiation, with lymph node and diffuse organ metastases. The sublingual lesion presented as a tumefaction on the floor of the mouth, causing masticatory discomfort. Histologically it was formed by epithelial cells with high-grade cytomorphological features with a large central area of chondroid differentiation. The case was clinically and pathologically challenging, given the rarity of the primary MpBC and the improbable secondary location. Alternative primary salivary gland tumors with chondroid differentiation were considered, but ultimately the clinical integration was crucial in establishing the diagnosis of MpBC metastasis to the sublingual gland.

Background: Mandibular Advancement Devices (MADs), inserted in non-surgical treatments for obstructive sleep apnea and hypopnea syndrome (OSAHS), are used intra-orally during the sleep period, with the aim of promoting mandibular protrusion. The aim of the study is to analyze the changes in the upper airway after the use of an MAD in the treatment of OSAHS. Methods: 60 patients diagnosed with OSAHS, as established by the Sleep Medicine Service, underwent treatment with the Silensor SL device at the Stomatology Service of the University Hospital Center of Coimbra, from January 2018 to January 2019. All patients completed two polysomnographies and two lateral teleradiographies: one before starting treatment (T0) and one after 1 year of treatment (T1). In the lateral teleradiography performed after one year of treatment, the patient had the MAD placed intra-orally. The linear measurements of the airspace proposed by the Arnett/Gunson FAB Surgery cephalometric analysis were measured at four craniometric points: A, MCI, B, Pog. Results: The results demonstrate an anteroposterior airway enlargement in two of the four points studied with the MAD placed intra-orally (B and Pog point). The greatest average increase is observed at point Pog (3 mm), followed by B (1 mm), and finally, point A (0.6 mm). Conclusions: This study proved that there is an improvement in anteroposterior measurements at various points in the upper airways after treatment with MAD.

Objetivos: O estudo apresentado tem como objetivo avaliar a eficácia do dispositivo Silensor SL no tratamento da síndrome de apneia/hipopneia obstrutiva...

O duplo retalho de deslizamento em ilha do tipo V-Y constitui uma opção viável para a reconstrução de defeitos labiais, com resultado cosmético-funcional favorável. Apresenta-se o caso de uma mulher com um carcinoma basocelular da região labial superior tendo sido reconstruída, após excisão, com recurso a retalho duplo de deslizamento em ilha. Os autores descrevem a técnica cirúrgica bem como as principais vantagens e aplicabilidade da mesma.
