Abstract: Papillary hemangioma is a recently described benign hemangioma that typically presents on the head and neck of otherwise healthy individuals. It comprises branching papillary structures that protrude into the lumen of ectatic thin-walled vessels. Glomeruloid hemangioma (GH) is a similar, but unique, entity that occurs in patients with POEMS syndrome. The additional clinical implications of GH make distinction from papillary hemangioma critical. An additional case is herein presented and the literature on the subject reviewed. Potential differential diagnoses are discussed, with particular emphasis on the distinction from GH.
Hemangiomas are the most common benign liver tumor, found in 5-7% of patients. While benign, they can cause discomfort, hemorrhage, and consumptive coagulopathy (Kasabach-Merritt syndrome). Complication risk increases with size, and those>4 cm are considered ‘giant’ hemangiomas. Treatments include observation alone, surgical resection, transarterial embolization (TAE), radiation, RF, and medical therapy. While treatment is generally offered for symptomatic giant hemangiomas, the exact role for TAE remains unclear.
ConclusionKnock-down of MALAT1 inhibits the growth of HemECs through regulating miR-206/VEGFA axis, indicating that MALAT1 is a potential therapeutic mechanism for the treatment of IH.

ConclusionsPresence of VBL does not appear to carry additional risk to mother or fetus during pregnancy
This article is structured as a practical review offering a systematic diagnostic approach to focal calvarial lesions, broadly organized into four categories: (1) pseudolesions: arachnoid granulations, meningo-/encephaloceles, vascular canals, frontal hyperostosis, parietal thinning, parietal foramina, and sinus pericrani; (2) lytic: fibrous dysplasia, epidermal inclusion and dermoid cysts, eosinophilic granuloma, hemangioma, aneurysmal bone cyst, giant cell tumor, metastasis, and myeloma; (3) sclerotic: osteomas, osteosarcoma, and metastasis; (4) transdiploic: meningioma, hemangiopericytoma, lympho ma, and metastasi...
In this study, thirty deep IHs were included, and a fractional 2940nm laser was applied with 2-weeks intervals. Topical timolol maleate 0.5% was applied under occlusion for 30 minutes four times/day for 24 weeks. The plasma concentration of timolol maleate was monitored for 0.5h after the first treatment. The HAS scores and the depth, lateral diameter, vertical diameter of hemangiomas were evaluated before treatment, at 8 weeks and 24 weeks of treatment, and at 4 weeks after treatment.Results: Twenty-three patients (76.7%) demonstrated excellent regression, 4(13.3%) showed good response, and 3(10%) experienced moder...
