BACKGROUND: Angioma serpiginosum (AS) is a rare vascular abnormality consisting of proliferation and dilation of superficial blood vessels in the skin. AS typically presents in the first 2 decades of life and remains stable with time. CASE SUMMARY: We report the case of a 13-year-old female with an acquired, recurrent erythematous lesion with serpiginous borders on her left upper arm. Over several years, the lesion reappeared then disappeared 12 to 15 times. At one point, she developed a tender red nodule within the lesion; consequently, a biopsy was taken, revealing dilated telangiectatic vessels in the dermal papillae with mild, focal extravasation of erythrocytes...

BACKGROUND Invasive mucinous adenocarcinoma (IMA) is a rare variant of adenocarcinoma of the lung. It frequently shows KRAS mutations, while ALK rearrangement is exceedingly rare. We present a case of ALK-rearranged IMA of the lung presenting with an unusual pattern of brain metastases, radiologically mimicking a cavernous angioma. CASE REPORT A 44-year-old non-smoker female was first diagnosed with lung right lower lobe IMA with ALK rearrangement. Five years after surgery followed by chemotherapy, she developed a sudden onset headache...

Inducing therapeutic angiogenesis to effectively form hierarchical, non-leaky networks of perfused vessels in tissue engineering applications and ischemic disease remains an unmet challenge, despite extensive research and multiple clinical trials. Here, we use a previously-developed, multi-scale, computational systems pharmacology model of human peripheral artery disease to screen a diverse array of promising pro-angiogenic strategies, including gene therapy, biomaterials, and antibodies. Our previously-validated model explicitly accounts for VEGF immobilization, Neuropilin-1 binding, and weak activation of VEGF receptor 2 (VEGFR2) by the "VEGFxxxb" isoforms...

Eruptive pseudoangiomatosis is a rare viral exanthem characterized by acute onset of hemangiomata-like lesions, however, histological findings are distinct from that of true angiomas. This entity has been reported from Europe, North America, Japan, and Korea till date. Here, we report 12 cases of eruptive pseudoangiomatosis from a tertiary care hospital in Punjab.

Dermoscopy has been documented to increase the diagnostic accuracy of clinicians evaluating skin tumors, improving their ability to detect skin cancer and better recognize benign moles. However, dermoscopically "false positive" and "false negative" tumors do exist. False positive diagnosis usually leads to unnecessary excisions. False negative diagnosis is much more dangerous, since it might result in overlooking a cancer, with severe undesirable consequences for the patient and the physician. Therefore, management strategies should mainly focus on addressing the risk of dermoscopically false negative tumors...

Notable milestones in the treatment of vascular lesions have been achieved over the past century. Many cutaneous vascular lesions can be successfully treated with lightbased devices. In this review, we will discuss the treatment of port-wine birthmarks, lymphatic malformations, infantile hemangiomas, rosacea, venous lakes, pyogenic granulomas, cherry angiomas, and angiofibromas using lasers, total reflection amplification of spontaneous emission of radiation, intense pulsed light, and photodynamic therapy. In addition, for several of these diagnoses, we will review medical therapies that can be combined with light-based devices to provide enhanced results...

Cavernous hemangioma in the sellar region is quite rare with only a handful of cases being reported in the English literature. Its clinical manifestations and imaging characteristics can mimic those of a pituitary adenoma. We report two cases of recurrent sellar lesions, both of which were clinically suspected of being pituitary adenomas but histologically confirmed as cavernous hemangiomas. The first case is of a 67-year-old female whose initial resection was diagnosed as "venous angioma". Neuroimaging performed 27 years later demonstrated significant growth of the lesion involving the right cavernous sinus and encasing the right internal carotid artery...

Pilocytic astrocytoma (PA), featuring activation of the mitogen-activated protein kinase (MAPK) pathway, is the most common tumor of the pediatric central nervous system. However, it remains unknown whether MAPK activation is present in the reactive gliosis of non-neoplastic lesions. Therefore, we investigated the expression of MAPK in reactive gliosis associated with cavernous angiomas. Immunohistochemical expression and the extent of BRAF, ERK, p38, and JNK were investigated in 10 patients with gliosis surrounding cavernous angiomas (GS group) and 10 patients with PA (PA group)...

Cerebral arteriovenous malformations (AVMs) are rare vascular lesions potentially responsible for substantial neurological morbidity and mortality. Over the past four decades, radiosurgery has become a valid therapeutic option for many patients with small intracranial AVMs, but reports describing the use of robotic stereotactic radiosurgery (SRS) are rare. The purposes of this study are to describe the efficacy and toxicity of robotic SRS for AVMs and to review the literature. The reports of 48 consecutive patients treated with SRS were reviewed...

BACKGROUND: Hypertrophic olivary degeneration (HOD) is a rare phenomenon in the dento-rubro-olivary pathway due to lesion or disruption of the fibers of the Guillain-Mollaret Triangle. Hemorrhage of pontine and midbrain cavernous angiomas rarely can lead to hypertrophic olivary degeneration (HOD) portending neurological deterioration and possible concomitant life-threatening complications; for this reason, it may define a poignant consideration in planning intervention. CASE DESCRIPTION: 57-year-old female with known midbrain-pontine cavernous angioma...

Klippel-Trenaunay-Weber syndrome (KTWS) is a rare congenital vascular disorder characterized by the classic triad of cutaneous nevi, venous varicosities, and osseous and soft tissue hypertrophy of the affected limb. Various vascular anomalies of the central nervous system have also been described in patients with this syndrome. The English-language literature to date contains six reports of associations between KTWS and spinal cord cavernous angioma (CA), but the management of these patients has not been well described...

Epithelioid hemangioendothelioma (EHE) is an infrequent vascular tumor that has an intermediate prognosis between the prognosis of the angioma and that of the angiosarcoma. Its evolution is characterized by a tendency to recurrence and metastases. EHE has been reported in locations such as: lungs, liver, bone and soft tissues. There are very few reports of cases involving the head and neck region. The occurrence of EHE in the orbital region and/or the eyelid is extremely rare. The authors report a case of EHE in the right upper eyelid...

Angioma or hemangioma is a benign vascular tumor which rarely occurs in muscles. It mostly affects young adults. We report a case of intramuscular hemangioma of quadriceps with painless extension contracture of the knee and a mass in the thigh. MRI allowed preoperative diagnosis of intramuscular hemangiomas and, primarily, T2-weighted images allow specific topographic assessment and give an indication to the diagnosis.
