Abstract:
Objective To explore the chnical manifestation,pathological features and characteristics of lobular capillary hemangioma (LCH),so as to raise awareness.Methods Sixty-nine cases of LCH were studied by routine histopathologic and immunohistochemical examinations.Results The age range of the 69 patients including 34 males and 35 females with LCH was 4-80 years,with an average age of 42 years.The lesions of 50 cases were located in head and neck region,and the other 19 cases were in other parts of the body,with 1 case in the left main bronchus and intracalvarium.The average diameter of the tumors was about 1 cm,and parts of the tumors showed polypoid masses.Most of the tumors were in the skin and mucosa.Granulomatous lesions showed the proliferation of thin-walled and thick-walled capillaries in a lobular pattern.The vascular interstitium was edematous and was infiltrated by the inflammatory cells.Immunohistochemical examination showed CD34 positive in the endothelial cells and smooth muscle actin positive in the peri-vascular spindle cells.Conclusions Studies of LCH show the obvious features on age,gender and diseased location,and very few have a relapse.Its pathogenesis is still unclear.LCH is rarely found in the trachea,and is more rarely in the central nervous system.So far,there is no case report to show LCH occurs both in the bronchus and intracalvarium.In the special case,the early lesion is found in the left main bronchus.Although the patient is treated,LCH still recurs for many times in a short period.Finally the tumor is also found in the intracalvarium.Therefore,it's critical to alert whether LCH also occurs in the important organs at the early stage.Complete surgical resection and / or adjuvant radiotherapy can avoid delaying the treatment and the subsequent serious outcomes.
