Oral intravascular papillary endothelial hyperplasia 总被引:1,自引:0,他引:1

Intravascular papillary endothelial hyperplasia (IPEH) is usually a cutaneous lesion thought to represent a peculiar manifestation of an organizing thrombus. IPEH can be subdivided into a pure form that occurs within a dilated vascular space and a mixed form that appears as a focal change within a preexisting vascular lesion, such as hemangioma. The principle significance of the lesion lies in the fact that it may be mistaken for angiosarcoma. Oral lesions are uncommon and the present paper reports on 16 new cases of oral IPEH, analyzing their clinical and histomorphologic features. Histologically, 11 lesions appeared in a pure form and 5 lesions in a mixed form. Thrombi were detected in all but one case. The most common location was the lip, followed in decreasing frequency by the tongue and buccal mucosa. Local excision was the treatment of choice. 相似文献

The peripheral calcifying odontogenic cyst (PCOC) is a rare lesion. The number of well-documented cases reported in the English-language literature until now is 38. The purpose of the present study is twofold: (1) to report seven new cases of PCOC and (2) to review and analyze the clinical and histomorphologic features of the previously reported cases of PCOC together with those of the present study. Most of the lesions were located in the maxillary and mandibular gingiva or alveolar mucosa anterior to the region of the first molar. Histologically, 66% of the lesions were of the cystic variant and 34% of the solid (neoplastic) variant. The terminology of the lesion and its histogenesis are discussed. 相似文献

Perhaps nowhere in medicine does the friction between physician and HMO translate into lost revenue more noticeably than in disease mnagement, where lack of doctor buy-in is a perennial complaint. The author, a former medical director knowledgeable about all aspects of DM, offers two methods by which health plans can overcome this obstacle. 相似文献

Four cases of an ulcero-proliferative lesion of putative histiocytic origin, arising in the oral cavity, are described. This lesion, which has not been defined previously, is easily confused histologically with a malignant process of lymphoid origin, thereby representing a pseudolymphomatous proliferation. Light microscopic, ultrastructural, and histochemical characteristics including immunoglobulin negativity, positive esterase reactivity, and positive peanut lectin binding support a histiocytic origin. These lesions are not associated with systemic disease or dissemination and heal spontaneously despite their worrisome microscopic appearance. 相似文献
