To explore the relationship between psychological factors and recurrent aphthous ulcer (RAU), oral lichen planus (OLP), and burning mouth syndrome (BMS) and to provide a reference for clinical diagnosis and treatment of the disease.

From July to October 2018, 50 patients with common RAU, refractory RAU, OLP and BMS were selected as the observation group, and 50 healthy participants without major systemic diseases and oral mucosal diseases matched for age and sex served as the control group. The psychological status of the subjects in each group was investigated by questionnaires, including the generalized anxiety disorder 7-item scale(GAD-7) and the patient health questionnaire-9 (PHQ-9).

Compared with the control group, the PHQ-9 scores in the refractory RAU, common RAU, OLP and BMS groups were higher than those in the control group (P < 0.05), and the GAD-7 scores in the refractory RAU, OLP and BMS groups were higher than those in the control group (P < 0.05). In the RAU group, the GAD-7 score of intractable RAU was higher than that of common RAU (P < 0.05), and there was no significant difference in the PHQ-9 score (P > 0.05).

RAU, OLP and BMS are common psychosomatic diseases presented by patients in the Department of Oral Mucosal Diseases. Their occurrence and development are related to the psychological status of patients. A tendency toward anxiety is significantly more common among refractory RAU patients than common RAU patients.

To explore the etiology, clinical manifestations, diagnosis and treatment of verruciform xanthoma (VX) in adolescents to provide a reference for clinical diagnosis and treatment.

The clinical data of a case of a palatal mass in a juvenile were analyzed, and the related literature was reviewed.

The palatal mass was proven to be VX by histopathological examination. Surgical resection was performed, and the prognosis was good. A review of the literature shows that VX is a rare benign mucosal skin lesion of an unknown etiology, with an incidence of approximately 0.025%-0.094%; VX is mostly found in middle-aged people, with no significant difference by sex. The clinical manifestations are similar to those of a variety of diseases, such as squamous papilloma, verruca vulgaris, fibroma, warty carcinoma and squamous cell carcinoma, which are not easy to distinguish and require histopathological diagnosis. The treatment of choice is surgical excision, with a low recurrence rate.

In the clinical experience of solitary mucosal masses in juveniles, it is necessary to send biopsy for pathological examination and avoid overtreatment.
