Angiosarcoma of the oral cavity is extremely rare. A 77-year-old woman consulted to our hospital because of polypoid mass of the mandibular gingival. Physical examination showed polypoid reddish mass measuring 1.5 × 1.5 × 1 cm in the mandibular gingival posterior to the front tooth. Enucleation of the tumor was performed. Grossly, the tumor was not encapsulated. Histologically, the tumor consis...

The arterial vasculature in the floor region of the mouth and the submandibular region of the crab-eating monkey was studied by the acrylic plastic injection method. 1. The titled regions were found to be supplied by the hyoid branch and the sublingual artery arising from the lingual artery, and the submandibular glandular branch, the mylohyoid branch and the submental artery from the facial ar...

BACKGROUND All of oral hamartomas has been previously found in mandibular gingiva in younger calves, and were histologically diagnosed as a vascular hamartoma. This is the first case report describing a calf with a mass in the maxillary gingiva that was histologically diagnosed as a nasal tissue-derived hamartoma. CASE PRESENTATION A 13-day-old male Holstein calf presented with a horn-like ma...

Some lesions in the oral cavity and mostly on gingiva have predominant predilection towards females, and mostly occur in the first four decades of life when changes in sex hormone levels in blood are obvious. The present study aimed to investigate the presence and distribution of estrogen and progesterone receptors in peripheral giant cell granuloma (PGCG), pyogenic granuloma (PG) and periphera...

The metastasis of malignant tumors to the oral cavity remains a rare clinical entity. Most metastatic tumors have the propensity for involving the mandible rather than the oral soft tissues. Herein, we describe an unusual case of ovarian mucinous cystadenocarcinoma that metastasized to the mandibular gingiva as an initial manifestation. There is little information regarding metastatic ovarian c...

The purpose of this study was to evaluate the inflammatory response in dento-gingival units with or without attached gingiva in monkeys. Two different types of dento-gingival units with or without attached gingiva were established in premolar and first molar areas of three monkeys. In the experimental group, a part of the keratinized gingiva was removed with periodontal scissors following mucop...

The misuse of various chemicals in dentistry may cause damage to gingiva and alveolar bone. In this case report, we describe necrosis of the gingiva and alveolar bone caused by acid etching. A patient whose caries on the cervical third of the root of his mandibular right first molar were treated 2 days earlier presented to our clinic with severe pain and discomfort in the treated area. Intraora...
