Superficial dermis shows thin-walled vascular spaces with slender papillary projections, but lacking erythrocytes in their dilated lumina. I would call this lymphangioma circumscriptum.

Agree lymphangioma circumscriptum- D2-40 stains lymphatic endothelium.

As usual in medicine , there is ongoing debate for the nomenclature.
Some people prefer to call this as superficial lymphatic malformation.As the word ''circumscriptm'' is misleading because many of such lesions has no identifiable margin.
As it is known to every one deep lymphatic malformation is term given to ''cystic hygroma''.It seems that the [color=#1C2837][font=arial, verdana, tahoma, sans-serif][size=4][background=rgb(241, 246, 249)]buttock is a common site because I saw a case in this location also.[/background][/size][/font][/color]

I see some papillary projections, hobnailed cells, a tendency to horizontal orientation of the vascular spaces, some of them dissecting the dermis. I would like to suggest the diagnosis of acquired progressive lynphangioma.

Lymphangioma circumscriptum.
This case has a classic clinical history that points to the most likely diagnosis, which is supported by the histology.
There is involvement of the papillary dermis by D2-40 positive thin walled vessels with no muscular component (although deep biopsies or excisions may show a muscular component in deeper vessels), proteinaceous fluid lacking significant red cells, and elevation of epidermal contour.
