Spontaneous fracture of hypertrophied genial tubercles.

A case of spontaneous fracture of hypertrophied genial tubercles is reported. This is an uncommon event with only six previously reported cases. This entity is usually associated with severe edentulous bone resorption, a condition related to the pathogenesis of this fracture. Clinical complaints include painful swelling of the floor of the mouth and impaired tongue function. If left untreated, mucosal inflammatory changes may appear and a biopsy should be performed. Total recovery is obtained after removal of the fractured fragments.

Atypical histiocytic granuloma of the tongue: case report.

Primary malignant lymphomas of the tongue have rarely been described, and reported cases are usually related to the posterior part of the tongue which is rich in lymphoid tissue, forming part of Waldeyer's ring. Making a distinction between pseudolymphoma and malignant lymphoma is important. Pseudolymphoma is a benign lesion not requiring aggressive therapy. Several lesions in the oral cavity, including atypical histiocytic granuloma, angiolymphoid hyperplasia with eosinophilia, and traumatic ulcerative granuloma with stromal eosinophilia have been described as having certain microscopic features similar to those of pseudolymphoma. Atypical histiocytic granuloma is not associated with systemic disease or dissemination and heals spontaneously despite its microscopic appearance.

Optic nerve blindness following a malar fracture.

Optic nerve blindness following a malar fracture is an uncommon and usually permanent complication. When the loss of vision is immediate and total, the prognosis is poor. The case of a patient who suffered immediate and complete loss of vision after a malar fracture is presented. Computed tomography revealed compression of the optic nerve by bony fragments. No improvement was observed after megadose steroids and surgical treatment. The incidence, pathogenesis, diagnostic approach and therapeutic possibilities are discussed and the importance of establishing precisely the moment of the loss of vision is stressed.

[Morphometric study of epithelial neoplasms of the parotid gland]. / Estudio morfométrico de las neoplasias epiteliales de la glándula parótida.

The histological diagnosis of parotid gland tumoral pathology is difficult in some cases. Morphometry provides a possibility to quantify the histopathology minimizing the risk of a misdiagnosis. On this basis, a morphometric study of the normal parotid tissue and 13 types of parotid tumors is carried out and nuclear Area, D. Circle, Form. PE, and Form. AR are calculated. Statistical analysis the results is made using the Student's "t-test" and significant differences between benign and malignant tumors and between each tumor and the remainder are obtained. Contribution of the results to the histopathological diagnosis is discussed.
