A wide range of masses develop in the nose, nasal cavity, and nasopharynx in children. These lesions may arise from the nasal ala or other structures of the nose, including the mucosa covering any surface of the nasal cavity, the cartilaginous or osseous portion of the nasal septum, the nasal turbinates, and the nasal bones. Lesions may also arise from the nasopharynx or adjacent structures and involve the nose by way of direct extension. The causes of nasal masses in children include congenital and developmental disorders such as congenital nasolacrimal duct mucocele, dermoid cyst, cephalocele, and nasal neuroglial heterotopia; inflammatory and infectious processes such as mucocele, polyp, and pyogenic granuloma; benign neoplasms such as infantile hemangioma and juvenile nasopharyngeal angiofibroma; malignant lesions such as rhabdomyosarcoma and nasopharyngeal carcinoma; and masses related to prior trauma such as septal hematoma...

BackgroundPropranolol is the first-choice treatment for severe infantile hemangioma (IH). However, 10- 30% of lesions relapse after propranolol treatment. The mechanisms underlying IH recurrence after propranolol treatment have not been completely elucidated.MethodsThis study combined an examination of hemodynamic changes with research regarding hemangioma stem cells (hscs) with differentially expressed microRNAs (miRNAs) to identify the factors affecting IH recurrence after propranolol treatment. Hemodynamic changes were monitored in 21 recurrent cases using high-frequency color Doppler ultrasound, and hscs were treated with different concentrations of propranolol...

Infantile hemangioma is the most common benign tumor in infants. Many studies have confirmed that basic fibroblast growth factor (bFGF) and its key receptor FGFR1 are highly expressed in hemangioma. Moreover, several miRNAs can regulate angiogenesis. In this regard, miR-424 often plays a role as tumor suppressor gene. This study was designed to investigate the mechanism of miR-424 in infantile skin hemangioma. Our results showed low expression of miR-424 in infantile skin hemangioma tissues, and that miR-424 overexpression downregulated FGFR1 expression in hemangioma-derived endothelial cells, while miR-424 inhibition upregulated FGFR1 expression...

Although infantile hemangiomas is benign, its rapid growth may induce serious complications. However, only one drug Hemangeol™ has been approved by US Food and Drug Administration (FDA) to treat infantile hemangiomas. Thus it is necessary to develop novel alternative drugs to treat infantile hemangiomas. Rapamycin is a well-know potent antiangiogenic agent, whereas the daily oral administration of rapamycin exerts undesired metabolic effects due to its inhibition of mechanistic target of rapamycin (mTOR) which is critical in cell metabolism...

Infantile hemangioma is a benign vascular neoplasm that spontaneously involutes over time. Management, when needed, consists of medications, laser treatment and surgical excision. We describe a 3-year-old girl who presented shortly after birth with diffuse cutaneous hemangiomas, hepatosplenomegaly with liver lesions, anemia, and acute heart failure. She was diagnosed with hepatic and cutaneous infantile hemangioma based on skin biopsy. She developed progressive pulmonary hypertension with numerous pulmonary nodules suspicious for pulmonary arteriovenous malformations...

Human angiosarcoma is a rare malignant vascular tumor associated with extremely poor clinical outcome and generally arising in the skin of head and neck. However, little is known about the molecular pathogeneses and useful immunohistochemical markers of angiosarcoma. To investigate the mechanisms of angiosarcoma progression, we collected 85 cases of human angiosarcoma specimens with clinical records and used ISO-HAS-B patient derived angiosarcoma cells. As control subjects, 54 cases of hemangioma and 34 of pyogenic granuloma were collected...

BACKGROUND: The Hemangioma Severity Scale (HSS) assesses the severity of an infantile hemangioma (IH). OBJECTIVE: First, to compare HSS scores between patients with IH for whom propranolol treatment was indicated at their first visit and those who were not treated. Second, to assess suitable cutoff values for the need for propranolol treatment. METHOD: All patients with IH who attended our tertiary referral center since 2008 and were 0 to 6 months of age at their first visit were included...

A 14-month-old Nepalese infant had developed a rapidly growing facial tumor originating from a dark spot on her upper eyelid. A cavernous hemangioma was suspected and treated with high doses of propranolol and prednisolone. Remission was dramatic. Histology confirmed alveolar rhabdomyosarcoma. Chemotherapy was planned but not carried out due to complicated logistics. The girl died at the age of 3. We present this case for discussion as to whether propranolol and prednisolone might be effective in rapidly growing rhabdomyosarcomas...

BACKGROUND: Oral propranolol is considered the first choice for the treatment of infantile hemangiomas (IHs). There is a concern that administering propranolol in newborns and infants could induce adverse effects in learning and memory processes in the long term. The purpose of this study was to assess cognitive and memory functions in children who had been treated with propranolol for IH during their infancy. METHODS: A total of 23 children between 5 and 7.5 years of age who had been treated with oral propranolol for IH during infancy were tested for cognitive functions with the Wechsler Preschool and Primary Scale of Intelligence, Fourth Edition (WPPSI-IV) test and for memory functions with the Test of Memory and Learning (TOMAL)...

BACKGROUND: Infantile hemangiomas (IHs) are the most common benign vascular tumor of infancy. They occur more frequently in female infants. The cause of hemangioma is currently unknown; however, current studies suggested the importance of estrogen (E2) signaling in hemangioma proliferation. METHODS: Hemangioma-derived stem cells (HemSCs) were cultured with estrogen for 48-72 h; the cell viability and proliferation were evaluated with the messenger RNA (mRNA) and protein expression levels of fibroblast growth factor 2 (FGF2), vascular endothelial growth factor-A (VEGF-A) and estrogen receptor-α (ER-α), by application of several in vitro assays, such as methyl thiazolyl tetrazolium (MTT), reverse transcriptase-polymerase chain reaction (RT-PCR), real-time PCR, enzyme-linked immunosorbent assay (ELISA) and Western blotting...

The discovery of beta-adrenergic blocker effects on infantile hemangiomas has affected the choice of treatment in recent years. Oral propranolol is effective in treating infantile hemangiomas, but the risk of systemic side effects remains a concern. Data from literature review reported positive clinical outcomes with no major adverse effects observed in children using topical beta-blocker such as timolol maleate. Topical application of timolol eye drop has been mentioned in few studies, most of which reported that the solution cannot stay on the site of application due to its fluidity...

Infantile hemangioma is the most common vascular tumor affecting infants, which is associated with clonal expansion of endothelial cells. The aim of this study is to determine the role of microRNA (miR)-143 in the growth and survival of hemangioma-derived endothelial cells (HemECs). We examined the expression of miR-143 in patients with proliferating-phase (n=10) and involuting-phase (n=8) hemangiomas. The effects of ectopic expression of miR-143 on the viability, proliferation, cell cycle distribution, and apoptosis of HemECs were explored...

Infantile hemangiomas are benign tumors of vascular endothelial cells (ECs), characterized by three distinct stages: proliferating phase, involuting phase, and involuted phase. The mechanisms that trigger involution of hemangioma into fibro-fatty tissue remain unknown. We report a novel mechanism by which M1-polarized macrophages induce endothelial-to-mesenchymal transition (EndMT) and promote hemangioma regression. M1- but not M2-polarized macrophages induced EndMT in ECs. Tumor necrosis factor-α and, to a lesser extent, IL-1β and interferon-γ were the most potent cytokines produced by the M1 macrophages that induce in vitro EndMT...
