We herein report the unusual case of a previously healthy young man who had spontaneous development of multiple lobular capillary hemangiomata disseminated over the integument. Based on the observation that the single lesions exhibited (immuno)pathologic and ultrastructural features similar, if not identical, to those of late-stage pyogenic granulomas, we propose to nosologically include our patient's eruption within the disease spectrum of pyogenic granuloma. As opposed to the occurrence of localized forms of pyogenic granuloma, the disseminated eruption seen in our patient and in other patients whose cases are reported in the literature cannot be ascribed to physical trauma. As some of these latter patients suffered from an underlying malignant neoplasm, it is tempting to speculate that both exogenous (eg, trauma) and endogenous (eg, tumor cells) factors can lead to the release of mediators promoting the development of these vascular neoplasms.

UI MeSH Term Description Entries
D008297 Male Males
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
D006391 Hemangioma A vascular anomaly due to proliferation of BLOOD VESSELS that forms a tumor-like mass. The common types involve CAPILLARIES and VEINS. It can occur anywhere in the body but is most frequently noticed in the SKIN and SUBCUTANEOUS TISSUE.
