Bizarre Parosteal Osteochondromatous Proliferation (BPOP) is a benign tumor-like lesion that has recently been reported to have an association with a specific translocation t(1:17)(q32;q21)[1]. Like other reactive periosteal lesions, BPOP can be diagnostically challenging, with the ever-present possibility of a potentially devastating erroneous diagnosis of malignancy. These lesions are often ...

Vascular anomalies are disorders of abnormal vasculogenesis or lymphogenesis. All types of vascular anomalies may involve the airway, causing varying degrees of upper airway obstruction as well as dysphagia and bleeding. Certain signs and symptoms may implicate airway involvement with a hemangioma or vascular malformation. It is necessary to distinguish ...

Vascular anomalies are localized defects of vascular development. Most of them occur sporadically (ie, there is no familial history of lesions, yet in a few cases clear inheritance is observed). These inherited forms are often characterized by multifocal lesions that are mainly small in size and increase in number with ...

Sirolimus (Rapamune), a mammalian target of Rapamycin (mTOR) inhibitor, which has been used extensively in children following solid organ transplantation, has been demonstrated to have anti-angiogenic activity in pre-clinical models. Limited experience suggests that it may have application to the treatment of vascular lesions. We describe our experience with a ...

To date, there are no widely accepted neuropathological criteria for vascular dementia, although creating such a standard is ranked high on the wish list of all the researchers in this field. Such criteria would make it possible to perform large multicentre clinicopathological studies and, consequently, to better understand which, how, ...

Hamartoma is a proliferation of normal tissues that are considered endogenous to the site of occurrence. In the head and neck region, hamartomas composed of other tissues different from blood and lymphatic vessels (hemangiomas and lymphangiomas) are very uncommon. We report an unusual case of upper lip angiomyolipomatous hamartoma in ...

Giant cavernous malformations (GCM) are very large, low-flow vascular malformations, which usually have atypical imaging features and are commonly misdiagnosed preoperatively as neoplasms or vascular malformations. These lesions have mostly been reported in children. As cavernomas show different features in children compared to adults, we evaluated the imaging features of ...

Cerebral cavernous malformations (CCMs) are vascular lesions of the central nervous system appearing as multicavernous, blood-filled capillaries, leading to headache, seizure and hemorrhagic stroke. CCM occurs either sporadically or as an autosomal dominant disorder caused by germline mutation of one of the three genes: CCM1/KRIT1, CCM2/MGC4607 and CCM3/PDCD10. Surgically resected ...

Like single-channel-type vascular malformations, combined lesions are categorized as slow-flow and fast-flow lesions. Many of the combined vascular malformations are associated with soft tissue and skeletal hypertrophy. This article discusses the diagnosis, management, and treatment of patients with capillary lymphaticovenous malformation, capillary-arteriovenous malformation, and capillary-arteriovenous fistulas and congenital lipomatous overgrowth, ...

Cavernous malformations (CMs) are a subset of neurovascular malformations, which include arteriovenous malformations (AVMs), venous malformations, and capillary telangiectasias. CMs are referred to by many names, which may contribute to their being mistaken for malignant entities such as angiomas or hemangiomas. They are not, however, neoplastic; they are true vascular ...

Many lesions can masquerade as deep infantile hemangioma, the most common tumor of infancy. We describe an infant with infantile hemangioma and concomitant metastatic subcutaneous neuroblastoma mimicking deep hemangioma. The patient presented at 8 months of age with 3 superficial infantile hemangiomas as well as 3 subcutaneous masses. History, physical ...

Intracranial vascular lesions are known to affect 2% to 4% of the population, predisposing those affected to a lifetime risk of hemorrhagic stroke, ischemia, focal neurologic deficits, or epileptic seizures. These lesions constitute a heterogeneous group, with different lesion types characterized by distinct biologic mechanisms of pathogenesis and progression. In ...

The promontory sign was described 27 years ago and it was claimed to be useful in the diagnosis of early stages of Kaposi sarcoma. However, it is not pathognomonic, because it has also been described in angiosarcoma and in benign vascular tumors. Some authors claim that some reactive vascular lesions ...

Vascular tumours (haemangiomas and malformations) are common tumours of infancy and childhood. They represent a group of mostly benign conditions, which present early, can grow rapidly and be symptomatic or disfiguring. There are various management options, with different cosmetic and functional outcomes. Haemangiomas and vascular malformations have different clinical courses ...

Arteriovenous malformations (AVMs) are rare vascular lesions that can be life-threatening due to potential massive hemorrhage. AVMs can be subdivided according to the type of vessel involved (capillary, venous, and arterial) and can be categorized, according to hemodynamic features, into high-flow and low-flow lesions. AVM of the jaws is an ...

Once thought to be a minor player in hemodialysis (HD) access dysfunction relative to outflow stenosis, inflow stenosis has recently come to be viewed as a major cause of access failure. Indeed, recent literature has shown that up to 40% of all accesses referred for dysfunction have an inflow lesion. ...

Vascular anomalies most frequently present at birth or in early childhood, and the craniofacial region is the most common site of involvement. A long history of misleading nomenclature born of confusion about the presentation and natural history of various vascular anomalies has made appropriate diagnosis difficult. The present article emphasizes ...

Osteolytic calvarial lesions are infrequent findings. Some cases are found incidentally during cancer staging or subsequent to unspecific symptoms. There are no standardized algorithms for the treatment of such lesions. Thus, the aim of this study was to describe the clinicopathological features and surgical outcome in various osteolytic calvarial lesions. ...

Extra-axial cavernous haem angiomas are uncommon lesions histologically identical to cavernomas in other locations. However, their radiological features and clinical behaviour may differ. They are frequently misdiagnosed preoperatively, as they often mimic other tumours. We describe a patient suffering from loss of the sense of smell, due to a cavernous ...

Paracoccidioidomycosis is the most prevalent human mycosis in Latin America. Cutaneous lesions are extremely painful and sensitive, and current treatment with antifungal drugs is lengthy and may cause side effects to patients. In this perspective, the helium-neon (HeNe) laser emerges as a novel therapy form due to its ability to ...

Vascular anomalies are congenital errors in vascular development. They frequently involve the head, neck, and oral cavity. Subdivided into vascular tumors (hemangiomas) and vascular malformations, vascular anomalies remain poorly understood. However, growing interest and recent advances in the diagnosis, management, and molecular characterization of these lesions are improving treatment strategies. ...
