A parotid gland mass with presenting features of malignancy is a diagnostic and therapeutic challenge. The histological nature of the lesion must be clearly determined before proceeding with facial nerve sacrificing surgery. Although rare, tuberculosis of the parotid gland must be included in the differential diagnosis of a parotid gland mass especially when the social characteristics of the patient suggests a mycobacterial infection. Primary tuberculosis of the parotid gland is generally encountered among populations with a high incidence of pulmonary disease. The difficulty in the differential diagnosis of a parotid gland malignancy may be helped by a high degree of clinical suspicion, since laboratory tests generally do not identify the specific causative organism. This article reports the first case of parotid gland tuberculosis with clinical and radiodiagnostical features simulating malignancy in which the diagnosis was confirmed by the polymerase chain reaction (PCR).

This paper presents an interesting case of a severe spontaneous haemorrhagewithin the parotid gland in an adult. A rapidly enlarging parotid mass with absence of causative trauma, inflammation or vascular abnormality, raised the suspicion of a neoplasm. Ultrasound, computed tomography (CT) and tissue biopsy, however, have shown only changes suggestive of previous haemorrhage and no evidence of malignancy. A 30-year review of theliterature revealed no similar case reported previously.

In 1923, Masson described a neoplastic process consisting of papillary hyperplasia of the endothelial cells, with a consequent obliteration of the vascular lumen, followed later by degenerative changes. Masson coined the term vegetant intravascular haemangioendothelioma, however, these days it is more commonly known as papillary endothelial hyperplasia (PEH), or by the pseudonym, Masson's tumour. Although relatively rare, there are numerous accounts of PEH in the literature, describing its predilection for the head and neck region. Our case report describes the finding of a PEH within the paranasal sinuses, a site not previously mentioned even in the largest of series found on literature search. We will then discuss the relevant histological features of the lesion, and its natural history.

A case of a solitary fibrous tumour arising in the deep soft tissues of the neck is reported. This rare tumour has not previously been described in this site. We discuss the clinical presentation and pathological features.
