OBJECTIVE: Arginine vasopressin hormone-secreting olfactory neuroblastomas are extremely rare, with fewer than twenty cases reported in the literature. Two of these cases, both initially presenting with the syndrome of inappropriate antidiuretic hormone, are presented. The second tumour was successfully identified using somatostatin receptor (octreotide) radiographic scintography. METHOD: The pathological specimens ...

The dura provides an excellent protection against infiltration by malignant tumours. It is extremely rare for glial tumour cells to infiltrate the dura and subsequently invade adjacent structures. We report an interesting case of glioblastoma of the temporal lobe with spontaneous transdural spread to the skull base and infratemporal fossa. ...

A solitary fibrous tumour is an unusual spindle cell neoplasm that most frequently occurs in the pleura based intrathoracic region. In recent years attention has been drawn towards solitary fibrous tumours arising in extrathoracic sites. They are usually benign but malignant solitary fibrous tumours have also been reported (Nielson et ...

'Benign' aqueduct stenosis is a common cause of hydrocephalus in the paediatric population and is frequently treated by endoscopic third ventriculostomy. Occasionally, aqueduct stenosis can be a prelude to the development of other pathology, as is seen in these two cases of pineal tumours developing in patients whose hydrocephalus was ...

Chordoid meningiomas are a rare but increasingly recognized subtype of meningioma. Although some cases have been associated with systemic symptoms, in many instances the clinical features are indistinguishable from those associated with other subtypes of meningioma. Given the prognostic significance of the diagnosis of chordoid meningioma, careful consideration should be ...

INTRODUCTION: Meningioangiomatosis (MA) is a rare lesion, probably of malformative origin, consisting of meningovascular proliferation and leptomeningeal calcification. Patients with MA usually present with seizures or persistent headaches. Neurofibromatosis may be associated in a variable proportion of patients, while in others it may be sporadic. Surgical treatment is usually recommended, ...

We report a rare case of a 70-year-old patient who presented with undifferentiated malignant teratoma arising from a solitary testis. The literature review highlights the rarity of such tumour in this age group, and this may represent the oldest reported patient with non seminomatous germ cell tumour of testicle.

Epidermolytic acanthoma is an uncommon benign tumour mainly characterized histologically by a prominent epidermolytic degeneration of the keratinocytes of the upper layers of the stratum spinosum and of the stratum granulosum. The absence of desmosome involvement allows to differentiate this condition from others such as acantholytic acanthoma. We report the ...

We report a rare case of schwannoma of the conus medullaris. A 38-year-old female presented with pain and numbness in her lower limbs. Magnetic resonance imaging confirmed a heterogenous tumour of the conus medullaris. A subtotal resection was performed and histology confirmed schwannoma. The literature regarding these rare tumours, and ...

Tumours of perivascular epithelioid cells (PEComas) are being increasingly reported at visceral and somatic sites. Both benign and malignant variants have been identified, although clinical follow-up is often limited, which prevents meaningful predictions of behavior. We report the case of a malignant soft tissue PEComa with histologically confirmed regional lymph ...

Human papillomavirus (HPV) seems to be involved in head and neck carcinogenesis. To investigate this association, viral presence and expression were analysed by polymerase chain reaction (PCR)-based methods and correlated to tumour localization, clinical-pathological aspects, and alcohol and tobacco exposure in 65 patients. HPV DNA was found in 16 cases ...

We report two cases of spontaneous regression of hepatocellular carcinoma. Firstly, a 64-year-old man with alcohol related cirrhosis developed multiple liver tumours with elevation of the alpha-fetoprotein level at 915 ng/ml. A spontaneous regression of all the tumoural masses but one and normalization of the alpha-fetoprotein level was observed after ...

Headache can be either a late or early symptom of a brain tumour, depending on the location of the tumour. A constant, progressively increasing pain, or a change in the character of headache pain, may alert the physician to this occurrence. Fortunately most people with headache, even persistent or severe ...

While bone invasion and hyperostosis are frequent phenomena in meningiomas, primary intra-osseous meningiomas are rare. With only 15 reported cases, the osteolytic form of primary intra-osseous meningiomas is most uncommon. Its occurrence in the skull base is an extra-ordinary exception. We have reviewed and categorized the pertinent literature on intra-osseus ...

A peculiar type of meningioma with conspicious plasma-cell components is described. In accordance with the World Health Organization's Histological Typing of Tumours of the Central Nervous System, this rare clinical entity is recently designed as lymphoplasmacyte rich (LPR) meningioma. This type of meningioma is usually accompanied by prominent peripheral blood ...

Whereas testicular metastases are in themselves a rare entity, testicular secondaries from an appendiceal carcinoma have not yet been described. The case also illustrates the diagnostic dilemma of a tumour presenting as epididymo-orchitis. The authors present a case of an appendiceal carcinoma that, two years after radical therapy, manifested as ...

OBJECTIVE: Primary jugular foramen meningiomas behave differently from meningiomas arising elsewhere. The differences have important clinical, imaging, and surgical implications. We reviewed the imaging appearances of primary jugular foramen meningiomas and evaluated them for features that might assist in differentiating them from other common jugular foramen lesions. MATERIALS AND METHODS: ...

We report the case of a 72-year-old male presenting with a papillary adenocarcinoma of the middle ear. He had had a similar tumour excised from the ipsilateral nasopharynx seven years previously with no evidence of local recurrence. We conclude that this middle ear lesion possibly represents a second tumour. No ...

Cerebellar liponeurocytoma has recently been recognised by the 2000 World Health Organisation classification of tumours of the central nervous system as a distinct clinicopathologic entity. To our knowledge, 18 cases have been reported so far, under different names, such as "lipomatous medulloblastoma, lipidized medulloblastoma, neurolipocytoma, medullocytoma and lipomatous glioneurocytoma". The ...

BACKGROUND: Teratomas are exceptionally rare malformations in the head and neck region. They are mostly benign but as a direct result of their rarity, most clinician's experience of these tumours is very limited, and consequently most of the associated literature consists of single case reports. In this paper, however, all ...
