Microscopic (histologic) description
  • Large lymphatic channels in loose connective tissue stroma
  • Focally disorganized smooth muscle in wall of larger channels
  • Peripheral lymphoid aggregates
  • Often increased mast cells (Mod Pathol 1999;12:569)
  • Lymphangiomatosis: increase in size and number of thin walled channels; lymphatic spaces are interconnecting and dilated, lined by a single attenuated layer of endothelial cells involving the dermis, subcutis and occasionally underlying fascia and skeletal muscle
