[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.

[Romberg syndrome]. / Síndrome de Romberg.

Have been studied a 47 years old woman who present a facial deformity related to right hemifacial fat atrophy in dermal and subcutaneous tissues. This clinic finding with others from radiologic and electromyographic explorations are suggesting of Romberg's syndrome. We have done the more important differential diagnosis and reviewed the present surgical techniques for treatment.
