58-year-old female with hyperpigmented, thickened lesions on arms. A prior biopsy from the shoulder was read by someone as “morphea.” The present biopsy is from the right arm.

The additional interface element made me consider the following histological differential:
Sclerodermoid variant of dermatomyositis
Sclerodermoid graft-versus-host
Lichen sclerosus-morphoea overlap (I think there may be homogenisation of the superficial dermis here perhaps favouring the latter?).

I agree with Saleem. The vacuolar interface and sclerosis made me wonder about sclerodermatoid GVHD. LS/ Morphoea overlap is a good differential but CPC required.

Agree Abdul Chronic lupus erythematosus.

I think that serologic information is essencial, but the differential diagnosis could be LS/morphea overlap or even a Lupus erythematosus and morphea overlap. The clinical information would be mostly important for this last one.

Band of hyalinized collagen bundles in the upper dermis with epidermal interphase changes combined with sclerotic, thickened collagen with mucin between the bundles, consistent with LS/morphea overlap

[size=4][size=4]I think this is a scarring chronic lupus erythematosus. Microscopic pictures show an interface dermatitis with lymphocytic infiltrate around both superficial and deep vascular plexuses, and increased mucin between collagen fibers in reticular dermis.[/size][/size]
[size=4][size=4]An atrophic hair follicle can be found. It features vacuolar damage of the infundibular basal cells and an underlying fibrous tract. These findings, in addition to the presence of melanophages and sclerosis in upper dermis, explain the clinical characteristics of thickened and hyperpigmented lesions that probably also display alopecia.[/size][/size]

Too much mucin and interface dermatitis...I think chronic lupus.

Agreed. This is lupus. The patient has a positive ANA.
