Allergic contact dermatitis occasionally provokes atypical T-cell infiltrates which may simulate mycosis fungoides. Contact eczema pathology Five major pathological patterns were identified: lichenoid (45/107, 42.1%), perivascular (40/107, 37.4%), interface (11/107, 10.3%), spongiotic (7/107, 6.5%) and granulomatous (4/107, 3.7%). Lymphocytic vasculitis was present in 17 patients (15.9%), and Langerhans cell microabscess was seen in 4 (3.7%). Perivascular lymphocytic infiltrate.

Histopathologically, the majority of inflammatory skin diseases exhibit the basic pattern of perivascular dermatitis as described by Ackermann. With respect to the epidermis, the finding of interface dermatitis constitutes a key criterion for the classification of perivascular inflammatory patterns.

A pattern of subacute, chronic dermatitis or acute dermatitis may be seen. The dermal inflammatory infiltrate predominately contains lymphocytes and other mononuclear cells (figure 7). Allergic contact dermatitis occasionally provokes atypical T-cell infiltrates which may simulate mycosis fungoides. Contact eczema pathology

It is the breakdown of the red blood cells that leaves iron pigment behind that gives both the clinical picture and the histological picture. If you look carefully at the blood vessels in pigmented purpuric eruption, there may be a bit of endothelial cell swelling and some perivascular thickening.
