Plasma cell tumors are characterized by a monoclonal proliferation of immunoglobulin-secreting plasma cells. Dural infiltration of plasma cells without involvement of the parenchyma, leptomeninges or skull is a rare event. We present a 34-year-old man presenting with hallucination and amnesia. Magnetic resonance imaging revealed a left fronto-temporal mass with a dural tail mimicking meningioma. The mass was excised and histopathological examination revealed sheet of mature plasma cells. The cells were immunoreactive for kappa light chain, MUM1, CD38, and negative for epithelial membrane antigen. There was no recurrence after postoperative radiotherapy. Intracranial involvement from plasmacytoma should be considered in a case of solitary dural mass.KEywoRds: Plasmacytoma, Brain, Dura ÖZPlazma hücresi tümörleri immünglobülin salgılayan plazma hücrelerinin monoklonal proliferasyonuyla karakterizedir. Parankim, leptomeningsler veya kafatası tutulumu olmadan plazma hücrelerinin dural infiltrasyonu nadiren görülür. Halüsinasyon ve amneziyle gelen 34 yaşında bir erkeği sunuyoruz. Manyetik rezonans görüntüleme dural kuyruğu olan ve menenjiyomu taklit eden sol frontotemporal kitleyi ortaya koydu. Kitle eksize edildi ve histopatolojik inceleme matür plazma hücreleri tabakası ortaya koydu. Hücreler kappa hafif zincir, MUM1, CD38 için immünreaktif ve epitelyal membran antijeni için negatifti. Postoperatif radyoterapiden sonra nüks olmadı. Tek başına bir dural kitle varlığında bunun plazmositomun intrakranial yayılımı olabileceği göz önünde bulundurulmalıdır.
Gangliocytoma of the pituitary gland is a rare lesion that often occurs in combination with pituitary adenomas and the exact origin is the subject of discussion. We report a rare case of an intrasellar mass of combined gangliocytoma/ pituitary adenoma coexistent with Rathke's cleft cyst. A 50-year-old female was admitted to our hospital with headache, mild acromegaly, and bitemporal hemianopsia. Histologically the tumor was composed of triphasic component of pituitary adenoma, clusters of ganglion cells and small cysts embedded in a variably dense neuropil substrate. Immunohistochemical analysis revealed the ganglion cells and adenoma cells were positive for synaptophysin and neurofilament. The lining of Rathke's cleft cyst was immunoreactive for cytokeratin 8. The exact pathogenesis of combined sellar pathology is not clear yet. However, a common stem/progenitor cell origin of both the adenomatous and neuronal component of these lesions has been suggested. KeywOrds: Sella, Gangliocytomas, Rathke's cleft cyst, Pituitary adenoma ÖZHipofiz bezi gangliositomu sıklıkla hipofiz adenomlarıyla kombinasyon halinde görülen nadir bir lezyondur ve kesin kökeni belli değildir. Rathke yarığı kistiyle birlikte görülen kombine gangliositom/hipofiz adenomundan oluşan nadir bir intrasellar kitle bildiriyoruz. 50 yaşında bir kadın hastanemize baş ağrısı, hafif akromegali ve bitemporal hemianopsiyle yatırıldı. Histolojik olarak tümör, hipofiz adenomunun trifazik bileşeni, gangliyon hücreleri kümeleri ve değişken şekilde yoğun nöropil substratına gömülü küçük kistlerden oluşmaktaydı. İmmünohistokimyasal analiz gangliyon hücreleri ve adenom hücrelerinin sinaptofizin ve nörofilament için pozitif olduğunu gösterdi. Rathke yarığı kistini döşeyen tabaka sitokeratin 8 için immünoreaktifti. Kombine sellar patolojinin tam patolojisi henüz kesin değildir. Ancak bu lezyonlarda hem adenomatöz hem nöronal bileşenin ortak bir kök/progenitor hücre kökeni düşünülmektedir.
Ergotamine has been used for the treatment of migraine for many years, and its use in adults is considered to be safe and effective. In this report, we present a 22-year-old female patient, a known case of migraine, who was on ergotamine tartrate and presented with hypertension and renal failure. Renal biopsy indicated features of acute tubulo-interstitital nephritis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
