I agree the balance of features here are in favour of a subacute eczematous dermatitis rather than psoriasis. If solitary PAS strips for fungi would be mandatory and a drug reaction must alwasy be considered. MF can be spongiotic but usually still shows basal preference rather than the random exocytosis as in this case. It will be up to the clinician to take it from here. In this case the dermatosis responded to emolients and was considered to represent "asteatotic" eczema.

Subaute spongiotic dermatitis (eczema). This lower epidermal exocytosis remineds me with exanthematous drug reaction pattern!!

Features in favor of subacute spongiotic dermatitis

Was this a solitary lesion? The biopsy shows parakeratosis overlying an epidermis with irregular acanthosis, and spongiosis. There is some exocytosis of lymphocytes, but no Pautrier’s microabscesses. The histological features are most compatible with a subacute spongiotic dermatitis for PAS stain to exclude fungal infection. I think the degree of spongiosis argues against the diagnosis of mycosis fungoides. Also the intraepidermal lymphoid cells are not larger than those within the dermal infiltrate. If PAS comes negative I would consider eczema.
