Infantile hemangiomas are relatively common soft tissue tumors in infants and young children, with a prevalence of about 4.5% in full-term newborns. Subglottic Hemangioma （SGH） is a relatively rare type of hemangioma, and its special location often causes respiratory distress and potentially life-threatening conditions in infants. Therefore, it is necessary for clinicians to make an accurate diagnosis and formulate a detailed treatment plan based on the clinical manifestations, the auxiliary examinations, the medical history and the vital signs evaluation of patients.This review describes the pathophysiological mechanism of infantile hemangioma and provides a detailed discussion on commonly used treatment methods in detail.

The effect of topical propranolol gel on the levels of plasma renin, angiotensin II (ATII) and vascular endothelial growth factor (VEGF) in superficial infantile hemangiomas (IHs) was investigated. Thirty-three consecutive children with superficial IHs were observed pre-treatment, 1 and 3 months after application of topical propranolol gel for the levels of plasma renin, ATII and VEGF in Department of General Surgery of Dongfang Hospital from February 2013 to February 2014. The plasma results of IHs were compared with those of 30 healthy infants of the same age from out-patient department. The clinical efficiency of topical propranolol gel at 1st, and 3rd month after application was 45%, and 82% respectively. The levels of plasma renin, ATII and VEGF in patients pre-treatment were higher than those in healthy infants (565.86 ± 49.66 vs. 18.19 ± 3.56, 3.20 ± 0.39 vs 0.30 ± 0.03, and 362.16 ± 27.29 vs. 85.63 ± 8.14, P < 0.05). The concentrations of VEGF and renin at 1st and 3rd month after treatment were decreased obviously as compared with those pre-treatment (271.51 ± 18.59 vs. 362.16 ± 27.29, and 405.18 ± 42.52 vs. 565.86 ± 49.66 P < 0.05; 240.80 ± 19.89 vs. 362.16 ± 27.29, and 325.90 ± 35.78 vs. 565.86 ± 49.66, P < 0.05, respectively), but the levels of plasma ATII declined slightly (2.96 ± 0.37 vs. 3.20 ± 0.39, and 2.47 ± 0.27 vs. 3.20 ± 0.39, P > 0.05). It was indicated that the increased renin, ATII and VEGF might play a role in the onset or development of IHs. Propranolol gel may suppress the proliferation of IHs by reducing VEGF.

A pregnant lady in her third trimester presented with a rapidly growing right-sided nasal mass associated with epistaxis and nasal obstruction for six months. Examination showed a non tender, protruding mass completely occluding her right nostril. Wide surgical excision was done under anaesthesia. Histopathology revealed capillary haemangioma. In a gravid patient with a rapidly growing intranasal lesion, capillary haemangioma should be considered as a differential diagnosis.

OBJECTIVETo investigate the efficacy and side effect of topical beta-blocker (Timolol Maleate) in the treatment of periocular hemangioma in a prospective study.

METHODS432 outpatients with infantile hemangioma visited our special clinic service in Shanghai Ninth People's Hospital from July 2010 to December 2011. Among them, 12 superficial periocular lesions were selected in the study. Timolol was used topically on the lesion in every 12 hours. Two independent special doctors evaluated the results according to the pictures before and after four-week application of timolol.

RESULTSWere categorized into four levels: continuous growth (the lesion continues to grow), stable (no visible change), moderate (0-50% of regression) , perfect (more than 50% of improvement). Result of the 12 outpatients, 4 showed perfect result, 2 moderate, 4 stable and 2 continuous growth. No side effect was observed.

CONCLUSIONSTopical timolol is effective and safe in the treatment of superficial periocular infantile hemangioma. It could be considered as the first line treatment of proliferative superficial hemangioma.

We report the dynamic contrast-enhanced CT and histopathologic findings of a rare case of recurrent pulmonary capillary hemangiomas. The findings consisted of peripheral nodular enhancement at the early arterial phase and a subsequent "central filling-in" enhancement pattern on the delayed scans, which was identical to the well-known enhancement pattern of hemangiomas of the liver. Although there was no evidence of histological malignancy, pulmonary capillary hemangiomas manifested as multiple nodular lesions and showed postoperative recurrence.

OBJECTIVETo investigate the clinicopathologic features of pulmonary capillary hemangiomatosis (PCH).

METHODSThe clinical and pathologic profiles of 2 PCH cases were evaluated. Immunohistochemical study (EnVision method) was performed on fixed tissues. The biologic behavior was analyzed with follow-up data.

RESULTSThe main presenting symptom was dyspnea. Chest radiography of the two cases depicted diffuse, ground-glass nodules, accompanied by enlarged central pulmonary arteries. Microscopically, the most distinctive feature was proliferation of capillary channels within pulmonary interstitium and alveolar walls, accompanied by muscularization of arterioles. Immunohistochemical study showed an abundance of mast cells in the lesion, and staining for platelet-derived growth factor receptor-beta (PDGFR-β) localized to vascular smooth muscles surrounding the proliferating capillaries and the mast cells. The index of Ki-67 was less than 1 percent and the p53 was negative.

CONCLUSIONSPCH is a rare vascular proliferative disease of yang patients. Increased number of mast cell and the up-regulation of PDGFR-β may suggest mechanism for PCH. The clinical and radiologic diagnosis of PCH can be very difficult, and the histological examination is regarded as the most reliable means to establish the diagnosis. Pathologists should improve their knowledge on PCH.
