the interdigitating junction between the epidermis and the papillary layer of the dermis, where the dermal papillae fit into corresponding evaginations on the deep surface of the epidermis.

dermoepidermal junction

; DEJ undulating basement membrane zone between superficial (stratum papillare) and basal layer (stratum basale) of the epidermis

pertaining to the dermis and the epidermis.

dermoepidermal junction
is straight compared to the undulating border in humans; consists of lamina lucida externa, lamina densa, lamina lucida interna and anchoring filaments.

band-like lichenoid lymphocytic infiltrates with vacuolar changes at the dermoepidermal junction,
Injury to the basal keratinocytes and other structures produce tiny vacuoles along the dermoepidermal junction on both sides of the basal lamina known as vacuolar alteration or vacuolization.
The bandlike infiltrate obscuring the dermoepidermal junction with cytoid body formation, confluent hyperkeratosis, irregular acanthosis, basal cell liquefactive degeneration, and apoptosis may closely mimic lichen planus.

To the side of the blister the epidermis showed scattered necrotic keratinocytes in mid-epidermis and at dermoepidermal junction.
Primary histopathologic feature shows the presence of a diffuse infiltrate of histiocytes in the upper dermis with close apposition at the dermoepidermal junction.
Histopathology showed similar findings as in the previous biopsy, but eosinophilic infiltrate was only present along the dermoepidermal junction.
Importantly, when a biopsy of a clinically typical lesion of LP shows equivocal histopathology, a positive lupus band test along the dermoepidermal junction supports a diagnosis of LP.
Histopathology results show epidermal atrophy, subepidermal separation, and haziness of the dermoepidermal junction.
Histopathology of involved skin showed increase in number of melanocytes along with basal layer degeneration and mild infiltrate at dermoepidermal junction (Figure 6).
