Oral lichen planus: a clinical and morphometric study of oral lesions in relation to clinical presentation.

Oral lichen planus (OLP) is a chronic inflammatory disease with different clinical presentations that can be classified as reticular or atrophic-erosive. Sixty-two OLP patients were studied to evaluate the clinical-pathologic characteristics of their OLP lesions and to investigate possible differences in their biological behavior. The most common clinical presentation was the reticular type (62.

Poorly differentiated oxyphilic (Hürthle cell) carcinoma arising in lingual thyroid: a case report and review of the literature.

Clinically significant lingual thyroid is an unusual developmental anomaly, and carcinoma arising in lingual thyroid, an extremely rare entity. Here we describe the cytologic, histologic, immunohistochemical, and ultrastructural findings of the first poorly differentiated oxyphilic (Hürthle cell) carcinoma described in lingual thyroid along with a review of the literature. Carcinoma arising in lingual thyroid was reported in 12 males and 21 females age 12 to 86 yr (mean age: 40).

Clinical and pathological characteristics of oral lichen planus in hepatitis C-positive and -negative patients.

The reported prevalence rate of anti-hepatitis C virus (HCV) antibodies in patients with oral lichen planus shows wide geographical variation and ranges from 0 to 65%. Certain characteristic clinical features have been attributed to oral lichen planus associated to HCV infection. The purpose of this investigation has been to assess hypothetical clinical differences, as well as differences in the intensity of the subepithelial inflammatory infiltrate between oral lichen planus-HCV +ve patients and oral lichen planus-HCV -ve patients.
