BACKGROUND Appropriate management of progressive, unverified brain lesions should be guided by conclusive pathological diagnosis. Stereotactic biopsy (SB) is established as a less invasive surgical procedure that provides diagnosis. In this prospective study, we analyzed the diagnostic difficulties and risk of SB in the various brain mass lesions, the rate(More)
Multiple sclerosis (MS) may sometimes present as a mass lesion that is clinically and radiologically indistinguishable from brain tumor. The initial recognition of such cases is essential to avoid a surgical intervention and supplementary treatment. Sometimes areas adjacent to a tumor may present similar histopathological features with non-neoplastic(More)
We report a new clinical variant of epidermolysis bullosa simplex with muscular dystrophy (EBS-MD) that was associated with cardiac involvement. A 33-year-old patient had atrial fibrillation, pericardial effusion, and hypokinetic left ventricular cardiac walls. The muscle biopsy material revealed diffuse endomysial fibrosis and small atrophic muscle fibers(More)
A 55-year-old man presented with oral mucosal ulcers, blackening of both hands, and hyperpigmentation on axillary, anal, and inguinal regions for the last 3 months, which were all progressive. The patient was referred to the oncology department with the diagnosis of acanthosis nigricans for investigation of an underlying malignancy. He was a smoker. A(More)
Dermatofibrosarcoma protuberans (DFSP) is an uncommon locally aggressive mesenchymal tumor with a high local recurrence rate. Atrophic DFSP is a rare variant of DFSP characterized by a non-protuberant lesion. We report on a 23-year-old female, who presented with an atrophic, asymptomatic macule on the right side of her back 2 cm in diameter. Dermatoscopic(More)
To the Editor, Solid organ transplant rejection is still a problem despite the use of immunosuppressive therapy. The currently available regimens for transplant rejection may predispose patients to malignancies such as nonmelanoma skin cancers and opportunistic infections [1]. Extracorporeal photopheresis (ECP) is a leukapheresis-based immunomodulatory(More)
Glioblastoma is very rare in the pineal region. We report a case of glioblastoma in this region. This is the 18th case of primary glioblastoma in the pineal region and the second case that survived over two years according the literature. A 60-year-old man admitted with headache and ataxia that continued for the last 3 months. Physical examination was(More)
We describe herein a patient with primary intracerebral malignant fibrous histiocytoma (MFH) to demonstrate this very rare central nervous system tumor. A 42-year-old male was admitted to our institute with the complaints of headache and speech impairment. Magnetic resonance imaging (MRI) revealed a tumor consistent with meningioma and we(More)
