It is nice to be back at the spot diagnosis site after a stressful and labor-intensive house move but we are getting things organized. Well done Mona for a great description and discussion. The lesion is indeed a lymphangioma and quite correctly. it could respresent the deep component of a lymphangioma circumscriptum or else a deeper variant such as a cystic hygroma. In lymphangiomatous KS, the changes are usually very focal and one would almost invariably see more typical features of KS adjacent to the lymphangiomatous element. Cirsoid aneurysm is characterized by admixed thick-walled arterial channels and thin-walled veins and therefore does not really enter the differential diagnosis.

Agree with my dear friend Mona but I wonder could we add circoid aneurysm to D.D or not

Dilated lymphatic channels, lined by single layer of endothelial cells, some are empty, some contain esinophilic protinaceous material, some contain RBC's. Lesion seems to be a deep lesion. Collections of lymphocytes are also seen. My Diagnosis from this magnification where I can't c the papillary dermis would be first cavernous lymphangioma (cystic hygroma), secondly it could be a lymphangioma circumscriptum with a deep component.. Acquired progressive lymphangioma and lymphangiomatosis are different with horizontally arranged irregular lymphatic channels dissecting inbetween the collagen bundles... Lymphangioma like KS is an important DDx but I think in it the channels are usually devoid of RBC's and are more grossly dilated, interconnecting and anastmosing with evident promontery sign and from such a magnification, typical areas of KS would have been apparent. Nice case!!!
