Tufted angioma (TA) is a rare, slow-growing, vascular lesion that commonly presents as a solitary macule, papule, or nodule arising in the soft tissues of the torso, extremities, and head and neck in children and young adults. Adult-onset cases have been infrequently reported. While typically benign, TAs may be locally aggressive. Complete physical examination and hematological workup are recommended in patients with TA to exclude the presence of Kasabach-Merritt phenomenon (KMP). The authors describe the case of a 69-year-old man with a contrast-enhancing frontal lobe lesion, with surrounding vasogenic edema, which was treated by gross-total resection...

Most common tumors of the spleen are hematologic and lymphoid malignancies. Non-lymphoid and non-hematologic tumors of the spleen are very rare, the most common of which are vascular tumors. This group of tumors in the spleen is composed of heterogeneous tumors such as hemangioma, angioendothelioma (AE), littoral cell angioma, and angiosarcoma. There are several histologic forms of AE such as epithelioid AE, Kaposiform AE, and myoid AE. Among these splenic vascular tumors, myoid angioendothelioma (MAE) seems to be the least common type...

BACKGROUND: Intradural extramedullary cavernous angiomas of the central nervous system are a rare type of cavernous angioma, but they can cause fatal subarachnoid hemorrhage. The efficacy of resection for this type of cavernous malformations remains uncertain. This is the first report to recommend surgical resection of these types of lesions regardless of the fatal condition. CASE PRESENTATION: Our patient was a 70-year-old Japanese man who experienced a sudden onset of an occipital headache, followed by bilateral abducens nerve palsy...

Cerebral cavernous malformation (CCM) is a congenital vascular abnormality that predominantly affects the central nervous system, but that sometimes encroaches other vital tissues, including the retina, skin, and even liver. The familial form of CCM (FCCM) is considered to be an autosomal dominant disease with incomplete penetrance and variable expression, which is often attributed to mutations in three genes: CCM1, CCM2, and CCM3. We screened a Chinese family diagnosed with FCCM by using Sanger sequencing...

Currently, there are no specific clinical and dermoscopic features for diagnosing truly amelanotic plantar melanoma (TAPM). The present study aimed to investigate the dermoscopic features of all clinical variants of TAMPS and to evaluate their histopathological correlations. A retrospective analysis of prospectively collected data was carried out during a 10-year period (2003-2013). We analyzed the clinical data of 1321 patients, who had received a histological diagnosis of melanoma at the Melanoma Unit of the University of Florence...

INTRODUCTION: Intramedullary cavernous angioma (ICA) is a rare lesion of the spinal cord, representing only 3% - 5% of central nervous system lesions. The coexistence of trigeminal neuralgia and refractory itch is very rarely encountered in clinical practice. To our knowledge, a report of an ICA with trigeminal neuralgia and local neuropathic itch has never been published to date. Thus, we present a very interesting case of a C2 ICA. CASE PRESENTATION: A 61-year-old female presented with right facial pain for three years, which was exacerbated by accompanying cervical pain and itch for one month...

BACKGROUND: Angiosarcoma is a rare malignant neoplasm derived from endothelial cells and its prognosis is poor because advanced angiosarcoma is resistant to standard chemotherapy, and new therapies are urgently needed. Heat shock protein 90 (HSP90) has been identified as a molecular chaperone that regulates various cancer-related proteins. Numerous clinical trials are testing the effectiveness of HSP90 inhibitors in various types of malignancies. OBJECTIVES: To investigate the role of HSP90 in the pathogenesis of angiosarcoma and whether inhibition of HSP90 may have anti-tumor activity...

RATIONALE: Von Hippel-Lindau (VHL) disease is a rare inherited, autosomal-dominant syndrome caused by heterozygous germline mutations in the VHL gene. VHL patients are prone to develop benign and malignant tumors and cysts in multiple organ systems involving kidneys, pancreas and central nervous system (CNS). The varied and complex clinical manifestations and radiological findings of VHL are of interest. PATIENT CONCERNS: We report a 38-year-old woman with a ten-year history of VHL disease involving both pancreas and biliary system...

A woman aged 60 years developed a Millard-Gubler syndrome after a diagnosis of a cavernous angioma in the median and paramedian areas of the pons. In this context, she presented a right VI nerve palsy, right conjugate gaze palsy, facial palsy and left hemiparesis. To improve the complete VI nerve palsy, we planned a modified transposition approach, in which procedure we made a partial transposition of vertical rectus with a silicone band that was fixated posteriorly. After the procedure, the patient gained the ability to slightly abduct the right eye...

Drug-resistant epilepsy, not associated with acute brain complications or central nervous system leukaemic involvement, can develop in patients treated for acute lymphocytic leukaemia during childhood. It has been postulated that this rare complication may be due to CNS oncological treatment neurotoxicity, related to intrathecal drugs, such as methotrexate, and brain radiotherapy. We report four patients who developed drug-resistant epilepsy sometime after receiving treatment for acute lymphocytic leukaemia...

Vascular lesions of the solid abdominal viscera may pose diagnostic and management issues. A 16-year old girl admitted to emergency department due to recurrent abdominal pain and diagnosed to have multiple vascular malformations of the spleen on imaging investigations. Littoral cell angioma was preoperative suspicion owing to no response of the vascular lesion to the propranolol. It turned out to be cavernous hemangioma on histopathology.

BACKGROUND: Among the rare intraventricular cavernomas, purely intra-aqueductal cavernomas are exceptionally rare. CASE DESCRIPTION: A 62-year-old patient presented with progressive headache, memory loss, gait instability, and urinary incontinence. Magnetic resonance imaging showed the presence of a mass lesion located in the lumen of the cerebral aqueduct, associated with triventricular hydrocephalus. CONCLUSIONS: We discuss the rationale that led us to treat hydrocephalus with neuroendoscopy, which offered the possibility to directly inspect the intra-aqueductal lesion, make the diagnosis of cavernoma, and treat symptoms resulting from hydrocephalus without increasing the risk of bleeding...
