Vaginal tumours are rare, and Brenner tumour is one of the most infrequent vaginal lesions. Brenner tumour is a transitional tumour that typically arises in the ovaries. Some cases have been reported in the broad ligament, uterus and paratesticular structures. Only five cases have been reported in the vagina. We report a sixth case and discuss the histogenesis of this tumour, as well as the differential diagnosis with the mixed tumour of the vagina.

Plexiform schwannoma is a form of schwannoma which usually involves cutaneous tissues. It cannot be easily differentiated from malignant tumors, especially deep or cellular lesions. We report a deep plexiform schwannoma which we place among the various benign or malignant nerve sheath tumors, which may or may not develop within the context of genetic disease. Finally, the differential diagnoses are discussed. Recognition of the lesion is necessary for appropriate treatment.

Cysts and bursae of the nasopharynx are uncommon and seldom symptomatic when compared with malignant tumors of this region. However, it is noteworthy that in the presence of symptoms, a good knowledge of their radiological appearance is useful to establish the correct diagnosis. Cysts of Rathke's pouch, pharyngeal bursa of Luschka, Tornwaldt's cysts, retentional cysts of the seromucinous glands, oncocytic cysts, intra-adenoid cysts, branchial cysts, prevertebral or retropharyngeal abscess and pseudocysts of the nasopharynx will be discussed in this paper.
