ABSTRACT
In the last 30 years, there has been a strong interest in vascular proliferations. Pyogenic granuloma was not only renamed lobular capillary hemangioma, but also the conceptual interpretation was also changed from an overgrowth of granulation tissue to a genuine hemangioma (or benign vascular neoplasm). We describe 19 cases of patients who presented clinically with a vascular lesion, characteristically a pyogenic granuloma or lobular hemangioma, where the histopathological findings led to the pathologic concern for a lymphoma of the skin. These benign lesions with a dense lymphoid infiltrate were further defined on the basis of different vascular and lymphoid immunohistochemical markers as inflammatory lobular hemangiomas. We propose that given the considerable histopathological overlap between acral pseudolymphomatous angiokeratoma, T-cell rich angiomatoid polypoid pseudolymphoma of the skin, and other designations of some of these vascular proliferations with a rich and dense lymphoid infiltrate, they might constitute a spectrum of vascular lesions with varying clinical presentations.
