This is the case of a young woman, 16-year-old, calling to our Department because of the appearance, in the floor of the mouth, of a mass progressively growing until about 5 cm diameter. Through fine needle biopsy was diagnosed of epidermoid cyst. Despite its size and infrahyoid site was removed successfully. Perusal review of last years bibliography and its variants.
Neurinomata developed from extracranial portion of hypoglossal nerve are very scarce. We report one case of neurinoma originated in the descending branch of hypoglossal nerve and not having found after careful perusal of the literature of this subject another case we consider the ours as the first portraying this type of pathology and its localization.
Pilomatrixial carcinoma is the malignant variety of pilomatrixoma. It is a malignant lesion, locally aggressive that can reappear, specially if not completely removed. Scanty are the number of cases listed in the literature (2). Although metastases are uncommon one or twice references can be found in the writings (1). We report 2 cases of pilomatrixial carcinoma located in the middle canthal and malar zones, which were treated surgically: excision of the tumor and reconstruction by means of a local rotation flap.
Having on base a wide and selective review of the literature, it has seemed to us interesting to detail the infective pathology on this location or sometimes occurring. This region is, as well will see, the seat of a rich pathology. We pretend on the other hand to reassess the importance of the meticulous examination of the oral cavity in "systemic problems". We describe the palatal infections divided in four groups: bacterial, viral, fungal and parasitory, according to the causal agent. We review the palatine manifestations of other fewer current syndromes as well.
The myomucosal flap from buccinator muscle is a versatile flap useful on reconstruction of defects located in the palatine region. We report the case of a vascular tumor located in the left palate which was removed and rebuilt with a myomucosal flap taken from buccinator muscle. We proceed previously to the embolization of its nutritional artery (a. palatina major).
The following presentation of 2 cases give us the chance of making a review of the current situation and the correct handling of the congenital preauricular sinuses. Although some authors consider this pathology within the group of latero-cervical fistulae, we think that they should be individualized. The most frequent sitting is before the helix. They are generally asymptomatic, and it is not strange that the motive of consultation are recurrent infections or following surgery. The treatment consists in complete operative resection.

Three cases of adenoid cyst carcinoma of the palate are reported. In this study clinical features, pathological findings, treatment and prognosis are analyzed. In the 1st and 2nd cases we unfortunately verified that the course of the tumors based in a slow-continuous infiltrating spread. Moreover, in our first patient a late diagnosis of it made the prognosis become worse. In the 1st one, radical surgery is proposed for the adenoid cyst carcinoma diagnosed at an early stage without tumoral dissemination.
We report a case of maxillary sitting of a calcifying odontogenic epithelial tumor (Pindborg's tumor). It is a benign tumor with similar microscopical findings with the ameloblastoma although its natural evolution is different. The tumor has an actodermal odontogenic origin. The stem cell from which it develops and its growth stimulus are unknown. Although the intermediary stratum of the enamel producing organ has been incriminated. A swelling of the maxillae or a casual finding--as the case reported--are the most common manifestations at beginning of these cases. The differential diagnosis depends on the radiological pattern we may find. Various surgical procedures may be considered optional. It could vary from enucleation to complete resection of the affected structure. Aggressive surgery is not indicated.
