<p>There is a known association between nevus of Ota and melanomas involving the brain parenchyma and/or the meninges. We present the unusual case of a 32-year-old African-American female with a nevus of Ota and a contralateral parenchymal, primary CNS melanoma. We discuss the unique features of this case and provide a brief review of the literature regarding nevi of Ota and associated CNS melanoma. Our patient is a 32 year-old, African-American female with a left-sided nevus of Ota who presented with a three month history of headaches and paresthesias involving her left face and arm. An MRI of the brain revealed a hemorrhagic mass in the right temporal lobe, which, after craniotomy, was determined to be a melanoma. Extensive imaging, ophthamologic examination and full-body skin examination revealed no other foci of melanoma. To our knowlege, this is the only case of a nevus of Ota associated with contralateral parenchymal melanoma in an African-American patient. The association of contralateral parenchymal primary CNS melanoma with nevus of Ota is extremely unusual.  Futhermore, despite the association of nevus of Ota with CNS melanoma, the literature does not support routine screening of patients with nevus of Ota for CNS melanoma with imaging modalities. </p>

Background: Myeloid sarcoma (MS) is a rare solid tumour made of myeloblasts or immature myeloid cells in an extramedullary site or in bone, associated with systemic hematologic neoplasms. When they occur in the brain parenchyma, they can often be misdiagnosed. Methods: The authors report a case of a 4-year old boy 6 months out of remission from AML, presenting with a short history of headaches and vomiting, and found to have a heterogenous contrast-enhancing lesion in the right cerebellar hemisphere, with differential diagnosis of myeloid sarcoma, astrocytoma, medulloblastoma and ATRT. Preliminary diagnosis was made flow cytometry from an intraoperative biopsy. The patient had a long course of chemotherapy and radiation, but eventually died from the systemic burden of his AML. Results: The authors present a literature review on 178 published cases of CNS myeloid sarcomas, and their radiological presentation and the basis of immunohistochemical and pathological diagnosis is discussed. Conclusions: Diagnosis rests on a combination of immunohistochemistry and histopathology of biopsied tissue. Surgical resection is controversial, especially given the efficacy of chemotherapy and radiation, and prognosis remains unclear. As with all uncommon and rare clinical entities, further investigation is warranted to determine prognosis and optimal management of CNS myeloid sarcomas.

abstract BACKGROUND AND IMPORTANCE: Arachnoid cysts have not been reported to be located within the brain parenchyma. We present a case of an arachnoid cyst that was contained entirely within the right frontal lobe devoid of communication with the subarachnoid space and ventricle. CLINICAL PRESENTATION: A 65-year-old woman presented with a 1-year history of progressive headache and nausea. Computed tomographic and magnetic resonance imagining scans showed a well-defined, nonenhancing mass measuring 5 × 5 × 3.5 cm in the right frontal lobe. The mass appeared to be contained entirely within the brain parenchyma. The patient underwent a right frontal craniotomy, at which time the cystic mass was identified in the brain parenchyma without any communication with the arachnoid space. The cyst contained a clear fluid, and its wall was excised. The fluid contents demonstrated a composition similar to that of normal cerebrospinal fluid. Histological and immunohistochemical examinations of the cyst wall were compatible with the diagnosis of an arachnoid cyst. Postoperatively, the symptoms of the patient resolved, and no recurrence was observed up to 6 months after removal. CONCLUSION: The present case showed an intraparenchymal arachnoid cyst arising in the frontal lobe. Although the etiology is not known, an arachnoid cyst should be included in the differential diagnosis of primary intracerebral cysts.

Purpose. To discuss two rare presentations of ocular rosacea in a Hispanic patient and an African American patient with unusual ocular manifestations. Case Report. Case  1: a 43-year-old Hispanic woman presented with right eye corneal perforation. Her prior medical history was significant for rosacea only, diagnosed clinically by a dermatologist. Her eye exam showed signs of bilateral ocular rosacea. An emergent full thickness tectonic corneal patch graft was done. The patient’s bilateral eye symptoms improved one month after initiating rosacea treatment. Case  2: a 51-year-old African American man with long standing history of untreated rosacea presented with bilateral peripheral corneal thinning with neovascularization that led to right eye corneal perforation. Glue and bandage contact lens were applied. The patient did well 4 weeks after starting antibacterial, oral steroids, and rosacea treatment. Discussion. Ocular rosacea can present in Hispanic and African American patients with severe manifestations such as corneal perforation.

Severe Pancytopenia

Cancers of the colon are commonly treated with fluoropyrimidines, which often cause severe toxicities in patients with certain variants in DPYD. Y186C (rs115232898) and a variant in the 3′ untranslated region (rs12132152) are uncommon alleles previously observed in African–Americans. An African–American female underwent 5-fluorouracil-based therapy (400 mg/m2 bolus, 1200 mg/m2/day over 46 h). The patient experienced severe pancytopenia after the first cycle. After 5-fluorouracil (5-FU) dose reduction (600 mg/m2/day), the steady-state 5-FU plasma concentration became 474 ng/ml (range 301–619 ng/ml) and increased following a subsequence dose increase (800 mg/m2/day; 1248 ng/ml). After a 1000 mg/m2/day dose resulted in myelosuppression, 5-FU was again de-escalated for the remaining cycles (600 mg/m2). The observed complications are likely a function of uncommon genetic variants that affect DPYD metabolism.

Background:Neurenteric cysts are congenital cysts of the central nervous system that are believed to be of endodermal origin. In this report we present the unique case of a supratentorial neurenteric cyst that is contained entirely within the brain parenchyma.Methods:Apatient presented with an intraparenchymal cystic lesion that was subsequently identified as a neurenteric cyst. This lesion is reviewed in light of the available literature.Case report:A 35-year-old female presented with a one year history of progressive headaches and seizure-like episodes. Her examination revealed no deficits. Magnetic resonance imaging showed a 4 cm x 4 cm x 4 cm cystic lesion within the parenchyma of the right frontal lobe. A right frontal craniotomy and complete excision of the cystic lesion was performed. Pathologic examination confirmed that it was a neurenteric cyst. Postoperatively the patient's symptoms improved.Conclusion:Review of the literature revealed this to be the first case of a surgically excised, pathologically confirmed supratentorial neurenteric cyst, contained entirely within the brain parenchyma.

Rosai Dorfman disease is a rare histiocytic disorder. It is also known as Sinus Histiocytosis. It is with massive lymphadenopathy involves an overproduction of a type of white blood cell. The disease is rarely associated with intracranial and intraorbital involvement. Intracranial Rosai-Dorfman can mimic meningioma. Other pathologies also underline its pathologies. Here, we report a nine-year-old boy with a history of proptosis of the right eye and presenting with multiple skull lesions. Histopathological study revealed Sphenopetroclival lesion, which features that of Rosai Dorfman Disease. His MRI scan of the brain was taken, which showed evidence of right optic nerve meningioma with sella and suprasellar extension, causing severe proptosis. The child underwent right frontotemporal craniotomy with petrosectomy and Transylvanian, subtemporal approach to multicompartmental Rosai-Dorfmans lesion. After four months, the patient had a recurrence of the disease on which chemotherapy and steroids were started, which also did not show much response while taking an MRI scan. A corticosteroid is a useful option in the Central Nervous System Rosai Dorfman disease treatment. But this patient showed a negative outcome to the treatment.
