Abstract
Intralymphatic histiocytosis (ILH) is a rare skin benign condition observed in a variety of inflammatory settings. It is characterized by the presence of ectatic dermal lymphatic vessels containing aggregates of histiocytes. Associated conditions that have been identified include rheumatoid arthritis, metallic orthopedic implants, inflammatory bowel disease, and malignancies of the breast, skin, and colon. Some cases with no attributable underlying cause have been described. The pathophysiology of ILH is not well understood. It has been proposed that it may represent macrophage migration during immune activation. Herein, we present the first description of ILH observed in the healing phase of cellulitis on the skin of the breast. Awareness of this possibility is important when the diagnosis of intravascular carcinomatosis is being considered.
