Metastasis to the finger of oral floor squamous cell carcinoma: A case report.

When cetuximab is used, diagnosing finger metastasis can be difficult due to the side effects of paronychia and color changes of nails. Finger metastasis may be a marker of multiple metastasis; therefore, it can lead to a poor prognosis.

Intraductal papilloma arising from sublingual minor salivary gland: case report and immunohistochemical study.

Intraductal papilloma is a rare benign salivary gland tumor. This lesion is commonly observed in the duct of the minor salivary gland, predominantly in lip and buccal mucosa, but the case in the sublingual region is quite rare. This report shows a first case of intraductal papilloma developed in minor salivary gland of sublingual region.

Widening a narrow posterior mandibular alveolus following extirpation of a large cyst: a case treated with a titanium mesh-plate type distractor.

Vertical alveolar augmentation by distraction osteogenesis has become a standard pretreatment of dental implants due to the main benefit of lack of donor site complications, and many reports have shown its benefit with various types of alveolar distractors. However, autogenous bone transplantation and/or guided bone regeneration techniques are still the standard treatment for correcting a narrow alveolar ridge because of few commercially available distractors for alveolar widening. In this article, we treated a case by a mesh-plate type of alveolar widening distractor for a narrow posterior mandibular alveolar ridge after extirpation of a large jaw cyst.

Breakage of internal maxillary distractor: considerable complication of maxillary distraction osteogenesis.

Maxillary distraction osteogenesis using intraoral distractors is now one of the standard treatments of maxillary retrusion. This report shows 2 cases of breakage of this internal maxillary distractor in patients with cleft lip and palate; one was observed during the distraction period and the other was during the retention period. The first case required a rotational movement of the distraction segment, and this movement caused the laterally dislocation of the posterior part of the distractor, where the distractor suffered some mechanical forces by mouth opening.
