Glioblastomas in children usually occur in the brainstem and are often untreatable and associated with an extremely poor prognosis. Such tumours may however occur in supratentorial locations more typically associated with adult gliomas, where the outcome is more variable, but still poor. We report the case of a boy with ...

Rhabdoid meningioma is a rare variant of meningioma, often found in tumour recurrences. We report a 55-year-old woman with a history of intraventricular fibroblastic meningioma, who developed headache and tinnitus 5 years after complete resection of the initial tumour. Imaging confirmed a recurrent tumour in the intraventricular location. Histological analysis ...

Parapharyngeal tumours are frequently encountered in clinical practice and are often difficult to diagnose upon clinical examination due to the anatomic complexity of the region. We report a rare case of extracranial meningioma of the parapharyngeal space in a patient with no history of von Recklinghausen's disease, family history of ...

Rhabdomyosarcoma is a rare malignant tumour occurring in the hand. Though the prognosis for this tumour is poor, when it occurs in the hand, early diagnosis is possible, since the swelling becomes clinically obvious. Radical surgical excision even at the cost of significant functional loss is recommended with possible reconstruction ...

Primary intraosseous meningiomas are a subtype of primary extradural meningiomas and constitute fewer than 2% of meningiomas overall, but they represent approximately two thirds of all extradural meningiomas. These types of meningiomas originate within the bones of the skull and thus can have a clinical presentation and radiographic differential diagnosis ...

Epithelioid trophoblastic tumour (ETT) is an unusual type of trophoblastic tumour, which can cause difficulties in diagnosis and (as a consequence) in treatment. The literature suggests that surgery should be the treatment of choice for ETT as it is not responsive to chemotherapeutic agents, used in the treatment of other ...

Extracranial metastases from primary central nervous system (CNS) tumours have rarely been reported in the literature, and glioblastomas and medulloblastomas constitute the majority of these. The tendency of supratentorial primitive neuroectodermal tumours (PNET) to spread within the CNS is well-known, but few cases of extracranial metastases of supratentorial PNET have ...

Angiomyolipomas are frequent tumours of the kidneys. They are very important in the differential diagnosis of other kidney tumours; sometimes they can present a large size and manifest as an acute massive retroperitoneal haemorrhage. They generally should not be treated unless there are life-threatening problems. In this case report, we ...

OBJECTIVE: Intramedullary teratomas are extremely rare tumours. A review of the literature found only reports of 59 cases, three of which were treated by us. The most common localisation for these tumours is in the medullary conus. According to our experience as well as more recent reports, MRI images allow ...

Most glomus tumours occur in the dermis and subcutaneous tissues. Lung glomus tumours are quite rare. The current authors present the first reported case of a lung-derived glomangiomyoma, the rarest variant of glomus tumour. A 56-yr-old female was admitted with haemoptysis. Chest computed tomography showed an approximately 5-cm-diameter mass in ...

Leptomeningeal carcinomatosis (LC) is a rare complication of solid tumours. We report two cases of leptomeningeal carcinomatosis in patients with oesophageal adenocarcinoma. Diagnosis of LC can be overlooked without a high index of suspicion. Multifocality of symptoms and signs is the hallmark of LC. The combination of cerebrospinal fluid cytology ...

It has been shown recently that Kasabach-Merritt phenomenon, the association of a vascular tumour and consumption coagulopathy, does not--as previously thought--complicate "classical" infantile hemangiomas but distinctive entities called kaposiform hemangioendothelioma (KHE) and tufted angioma (TA), both tumours on the same neoplastic spectrum. These tumours have been found in the neck, ...

Pulsatile tinnitus is an uncommon condition. We describe a case of pulsatile tinnitus and visually demonstrate a pulsating tympanic membrane caused by a postoperative cerebrospinal leak into the mastoid air cells following resection of a left temporal petrous meningioma. To our knowledge, this is the first case in the literature ...

Osteolytic lesions caused by chloromas or extramedullary myeloid tumours have been reported before. We present a case of localised osteolysis caused by a chloroma, in which complete repair of the bony lesion occurred following chemo- and radiotherapy. We believe that this unique presentation has never been reported before in the ...

By the frequent use of computed tomography or ultrasound the detection of incidentally found adrenal tumours has become a common problem. This is also reflected in the worldwide proliferation of literature over the past decades. Most incidentally-found adrenal tumours are benign non-functioning cortical adenomas. But benign functioning tumours producing aldosterone, ...

A chordoma which occurs as a primary tumour outside the axial skeleton is known as an extra-axial chordoma, parachordoma or chordoma periphericum. It is extremely rare and therefore survival, recurrence and the rates of metastasis are not known. Whilst few recurrences have been described, the extra-axial chordoma has the potential ...

A case of giant cell angiofibroma in a 73-year-old man is reported. The tumour was located in the upper-inner quadrant of the right orbit and recurred 16 months after surgical removal. The clinicopathological features of this rare neoplasm--that is nowadays considered a variant of solitary fibrous tumour--are reviewed and briefly ...

Extracranial meningiomas are rare. They account for only 2% of meningiomas compared to the much more common intracranial site. We describe a rare case of extracranial meningioma presenting as a neck lump in a patient with preexisting neck disease due to ankylosing spondylitis. Extracranial meningioma should be considered in the ...

Reoperative surgery through a previous pneumonectomy space focuses on the management of postpneumonectomy empyemas and bronchopleural fistulae. There are reports of elective tracheal resections done through the pneumonectomy space. We report two cases of successful excision of recurrent tumours (leiomyosarcoma and carcinoid) performed through the previous pneumonectomy space 2 and ...

Although rare, brain tumours represent one of the relatively larger groups of congenital neoplasias. Most studies on congenital neoplastic disease deal with several types of neoplasms and are dominated by leukaemias, retinoblastomas and systemic solid tumours. Few studies are dedicated to congenital brain tumours. We present nine newborns (four boys ...

Extracranial spread of meningiomas to involve the middle ear is very rare. We present the case of a 43-year-old woman with a known cerebellopontine angle meningioma who subsequently presented with left-sided otalgia and a middle-ear mass extruding through the tympanic membrane due to local invasion of the meningioma. The tumour ...

A case of epithelioid and spindle cell haemangioma of bone occurring in the proximal femur is presented. The tumour had typical microscopic features with a striking lobular pattern comprising spindled and epithelioid areas with admixed inflammatory cells. The case represents only the eighth reported example of this rare tumour, which ...

Extraspinal ependymomas are rare. The majority occur in the sacrococcygeal region. The subcutaneous variety accounts for approximately two thirds of cases, which are commonly misdiagnosed as a pilonidal cyst or sinus. Treatment is complete surgical resection. The role of coccygectomy is controversial. Adjuvant radiotherapy is of benefit to those with ...
