Ten years after the onset of hydroa vacciniforme (HV), a 16-year-old boy developed edema and red induration of the face, ears, and dorsa of the hands. Aggravation of cutaneous manifestations was associated with general malaise,
headache
, fever, lymphadenopathy, hepatosplenomegaly, and an increase of several serum enzymes. The vesicle was situated intraepidermally with thrombosis and hemorrhage underneath. This confirmed the diagnosis of HV. In addition, dense cell infiltrate was seen in deep dermis and subcutaneous tissue. Histologic and immunohistochemical studies of the dermal cell infiltrate and lymph node showed an infiltrate of helper T lymphocytes with an atypia and histiocytic cells (
S100
[-], alpha-subunit[+]). Hence, we concluded HV and malignant lymphoma coexisted in this patient.

Granular cell tumours of neurohypophysis are rare. These tumours are more often encountered as incidental autopsy findings seen in up to 17% of unselected adult autopsy cases. There are few reports of parasellar granular cell tumours large enough to cause symptoms. We present three cases of neurohypophysis granular cell tumour and a review of the literature. In one patient, the asymptomatic granular cell tumour was incidentally discovered at surgical removal of a corticotroph microadenoma. The remaining 2 patients had a symptomatic tumour which caused neurological symptoms such as visual disturbance and
headaches
and endocrine disorders such as hypopituitarism or hyperprolactinaemia. In these 2 cases, computerized tomography showed a well-circumscribed, contrast-enhanced, intrasellar and suprasellar mass. Magnetic resonance imaging demonstrated an isointense gadolinium-enhanced mass in T1-weighted images. Transsphenoidal partial resection was performed and histology was interpreted as a granular cell tumour. The immunohistochemical study was positive for glial fibrillary acidic protein (GFAP) and neuron specific enolase (NSE) in 1 of the 2 tumours and positive for
S100
protein and vimentin in both tumours but negative for CD68. The histogenesis of neurohypophysis granular cell tumours is still controversial but ultrastructural and immunohistochemical studies support the theory that they may arise from pituicytes, the glial cells of neurohypophysis. Management of these benign, slow-growing, tumours is based mainly on neurosurgical resection. Data from the literature do not support a beneficial effect of postoperative radiation therapy on postoperative recurrences.

The term "chordoid glioma" was recently introduced to denote a circumscribed, apparently low-grade neoplasm arising in or preferentially involving the third ventricle of middle-aged women. We report biopsy and postmortem findings in a 60-year-old woman with symptoms of forgetfulness,
headache
, and lethargy. Neuroimaging showed a contrast-enhancing third ventricular mass with obstructive hydrocephalus. The tumor was subtotally resected. Microscopically, it consisted of clusters and strands of epithelioid cells in a mucoid matrix. Its margins were remarkably discrete and showed little tendency to infiltrate surrounding brain parenchyma. The majority of neoplastic cells were glial fibrillary acidic protein (GFAP) and vimentin positive, whereas
S100
protein labeled only individual cells. Stains for epithelial membrane antigen (EMA) and cytokeratin were nonreactive. There was no evidence of neuroendocrine differentiation or expression of estrogen and progesteron receptors. Lymphoplasmacellular infiltrates were noted throughout the lesion and at the tumor-brain interface. The MIB-1 labeling index averaged 1.5%. At present, chordoid glioma is considered a glial neoplasm of uncertain histogenesis with distinct clinicopathologic features.

Sinus histocytosis with massive lymphadenopathy, also known as Rosai-Dorfman Disease (RDD), is an idiopathic histiocytic proliferation affecting lymph nodes. Although extranodal involvement has been reported in diverse sites, central nervous system (CNS) manifestation, particularly in the absence of nodal disease is uncommon. We report 11 cases of RDD primary to the CNS without evidence of other sites of involvement. The cases included 7 males and 4 females ranging in age from 22 to 63 years (mean: 41 y). The patients presented with
headaches
, seizures, numbness, or paraplegia. Eight cases involved the cranial cavity and three cases, the spinal canal. Lesions were most often extra-axial and dura based. Only one presented in the CNS parenchyma. Histologically, the lesions consisted of variable numbers of pale-staining histocytes with emperipolesis often overshadowed by extensive lymphoplasmacytic infiltrates and fibrosis in the background. Special stains for organisms were negative. By immunohistochemical analysis, the characteristic histiocytes were positive for
S100
protein and CD68 and negative for CD1a. Treatment consisted of surgical biopsy or excision. Follow-up, available for 10 cases with intervals ranging from 5 days to 42 months (mean: 15 mo), disclosed one patient dying of operative complications 5 days after biopsy and nine patients with no evidence of disease progression RDD should be considered in the differential diagnosis of inflammatory lesions of the CNS. Our study suggests that this entity may have been misdiagnosed in the past as plasma cell granuloma or inflammatory pseudotumor.

The May 2002 COM. A 38-year-old man presented with new onset seizures and a 69-year-old woman presented with bilateral
headaches
and episodes of syncope. Both were found to have extra-axial masses that were contrast-enhancing and thought to be meningiomas. Both had complete resection. Microscopic examination revealed an inflammatory lesion composed of plasma cells, scattered lymphocytes and numerous large histocytic cells, which exhibited emperi polesis and were CD1 a negative, but positive for CD68 and
S100
. The diagnosis of Destombes-Rosai-Dorfman Disease (DRDD) was rendered. Both cases had good long-term outcome. The differential diagnosis of inflammatory masses in the dura (plasmacytoma, lymphomas, plasma cell fibroma, angiofollicular hyperplasia [Castleman's-disease] and Langerhan's cell histiocytosis) are discussed.

Sinus histiocytosis with massive lymphadenopathy, also known as Rosai-Dorfman disease (RDD), is an idiopathic condition typically associated with cervical lymphadenopathy, fever and hypergammaglobulinaemia. Extranodal involvement has been reported in diverse sites such as the skin, upper respiratory tract, orbit and the central nervous system. We document a case of intracranial RDD in a 40-year-old woman with rapid evolution over a period of three months. Clinically, the patient suffered from
headache
. The MRT showed a left parietal tumour with dural attachment. Histologically, the lesion consisted of pale-staining histiocytes with emperipolesis, neutrophilic granulocytes and scattered lymphocytes. Focally, the granulocytes dominated the histological picture. By immunohistochemical analysis, the characteristic histiocytes were positive for
S100
protein, CD68 and FXIIIa, but negative for CD1a. No Birbeck-granula were detectable in electron microscopic analysis. Granulocytes showed a positive Anti-HHV6b immunoreaction. The tumour was diagnosed asA'an intracranial manifestation of RDD primary to the CNS with an unusual preponderance of neutrophilic granulocytes and with only scattered lymphocytes. The postoperative clinical staging showed no other manifestations of the disease. On postoperative MRI the lesion had been completely resected. No further therapy has been applied and the patient has had an unremarkable clinical course for the last ten months.

Glioblastoma multiforme is recognized rarely in the cerebellum. We describe a peculiar case with lipid accumulation in giant tumor cells, possibly the second example so far reported in this unusual location. A 46-year-old man with a 5-month history of
headache
, vomiting, dizziness and instability of gait, was found to have on magnetic resonance imaging an expanding mass situated deep in the left cerebellar hemisphere. The lesion was hypointense in T 1- and hyperintense in T2-weighted images, had poorly defined borders, peripheral edema and annular foci of contrast enhancement. Eight months after subtotal removal and radiotherapy, control MRI showed tumor recurrence with aggressive features. The patient was alive 15 months after operation but follow-up was eventually lost. Histologically, the tumor showed marked pleomorphism, with many giant cells characterized by finely vacuolated cytoplasm strongly suggestive of lipid accumulation. There were few, sometimes atypical mitotic figures and foci of endothelial proliferation. The tumor cells were strongly positive for GFAP, vimentin and
S100
protein, all of which stressed the foamy appearance of the giant cells. About 15% of nuclei were positive for Ki-67. We considered the case to be a so-called lipidized glioblastoma, first recognized as a subtype by Kepes and Rubinstein [1981]. Differential diagnosis with anaplastic pleomorphic xanthoastrocytoma is discussed.

Rosai-Dorfman disease (RDD) is a non-neoplastic proliferative histiocytic disorder that primarily affects lymph nodes (sinus histiocytosis with massive lymphadenopathy). Primary RDD of the central nervous system is most uncommon. We report on a 35-year-old man with isolated RDD of the meninges overlying the left cerebral hemisphere. Presenting signs and symptoms included severe progressive ipsilateral
headaches
of 4 months duration, as well as laboratory evidence of mild non-specific systemic inflammatory reaction. On magnetic resonance imaging, the lesion was seen as a contrast-enhancing, plaque-like thickening of the dura mater over the left convexity,without impinging on adjacent bone or cerebral parenchyma. Meningeal biopsy revealed a mixed mononuclear infiltrate dominated by CD68(+),
S100
(+), CD1a(-) non-Langerhans type histiocytes on a background of fibrosis. Bacteria, in particular mycobacteria, and fungi were excluded with special stains. Extensive clinical workup, encompassing computed tomography of thoracal and abdominal organs, bone marrow biopsy, and bronchoalveolar lavage failed to reveal any extracranial involvement. Laboratory tests for autoimmunity, including C- and P-antineutrophil cytoplasmic antibodies, antinuclear antibody, and serum rheumatoid factor, were negative. Methylprednisolone therapy induced complete remission of symptoms, with the neuroradiologic status remaining unchanged on follow-up after 2 months. We discuss the complex clinicopathologic differential diagnosis and therapeutic issues of this rare condition. While the correct diagnosis of central nervous system RDD is unlikely to be established without invasive procedures (biopsy), a conservative therapeutic approach may be considered a legitimate option.

We report a 40-year-old lady who presented with severe
headaches
, persistent microscopic haematuria and hypertension requiring anti-hypertensive medication. Investigations for secondary hypertension were all normal except for a CT scan. This indicated a complex cystic lesion, measuring 2.4 x 5 x 10 cms , arising from the right kidney. She underwent an open right partial nephrectomy. The patient made an un-eventful postoperative recovery and her blood pressure returned to normal. The mass had a smooth outer surface and the cut surface showed firm whitish tissue with a few small cysts. Microscopy showed a bland spindle cell lesion staining positively for SMA, desmin, caldesmon, focally for HMB45 amd very focally for
S100
. The mass was reported as a Perivascular Epitheloid Cell (PEC) lesion (PEComa) arising from the renal capsule. Perivascular Epitheloid Cell tumor (PEComa), a recently defined tumor, is extremely rare. The lesion presents a distinct muscular immunophenotype (actin+, desmin+), with co-expression of the melanogenesis marker (HMB45). This combined immunophenotype is a characteristic feature of the Perivascular Epitheloid Cell (PEC) lesions. PEComa's are usually benign, but cases have been reported in the literature which has an unfavourable outcome with metastatic dissemination. We report this case because of its rarity and also Renal Capsular PEComa should be considered as a rare cause of renal hypertension, which can be surgically cured.

If treatment-emergent central nervous system (CNS) symptoms following triptan therapy represent direct pharmacological effects of the drug, they should occur independent of response to active drug. However, if they represent unmasking of neurological symptoms of the migraine attack after pain is relieved, they should be more common in responders both to active drug and to placebo. To explore this issue, we evaluated the relationship between the CNS adverse events and treatment response following triptan or placebo treatment. We used pooled data from seven double-blind, placebo-controlled trials involving eletriptan 20 mg (E20, n = 402), eletriptan 40 mg (E40, n = 1870), eletriptan 80 mg (E80, n = 1393), sumatriptan 100 mg (
S100
, n = 275) and placebo (Pbo, n = 1024). Somnolence was more prevalent among 2 h
headache
responders than non-responders for all treatments, including E80 (8.8% vs. 5.0%; P < 0.05), E40 (6.4% vs. 5.0%; NS), E20 (4.0% vs. 2.0%; NS),
S100
(4.7% vs. 3.2%; NS) and Pbo (7.6% vs. 3.0%; P < 0.05). Similarly, the incidence of asthenia was higher among patients who responded to treatment compared with those who did not respond to E80 (15.2% vs. 7.8%; P < 0.05), E40 (6.5% vs. 3.6%; P < 0.05), E20 (6.5% vs. 1.0%; P < 0.05),
S100
(10.1% vs. 4.7%; NS) and Pbo (4.4% vs. 2.7%; NS). The generally higher rates of somnolence and asthenia in patients who respond to treatment suggests that these treatment-emergent neurological symptoms may represent the unmasking of CNS symptoms associated with the natural resolution of a migraine attack, rather than simply representing drug-related side-effects. The rate of somnolence in placebo responders is comparable to that in responders to E40 and E80, indicating that somnolence is related, at least in some important part, to
headache
relief and not treatment.
