My Internet connection went as I was typing midway. Obviously MF is not my first diagnosis! This is a spongiotic psoriasiform dermatitis with langerhans cells forming pityriasiform/ pautrier like abscesses. Tinea capitis would obviously have to be excluded. However with the history of hair loss, I did say I wondered about CTCL though I do not see any lymphocytic atypia. A contact allergic dermatitis mimicking CTCL would therefore would be my preferred diagnosis.

Skin shows hyperkeratosis, alternating para and orthokeratosis, psoriasiform hyperplasia and mild spongiosis. Two pseudopautrier microabcsesses (Langerhans cell collections) are aslo seen within epidermis. Mild llymphocytic exocytosis is noted. There is no epidermotropsim. There is also mild to moderate patchy upper dermal lymphocytic inflitrate. Features are those of a subacute spongiotic dermatitis. DD includes: seborrheic dermatitis, PRP and fungal infection (PAS required).

Spongiotic dermatitis. Probably Tinea capitis.

Late stage folliculitis decalvans vs. erosive psutular dermatosis. Dermatophyte infection does not fit with age and lack of eos. I'm curious regarding the diagnosis of case 668 Prof. McKee.
