[@SandhyaRamachandran]

great one... a small Q..since the spongiotic reaction pattern changes over time from acute to subacute to chronic, how do we still call it a spongiotic reaction pattern in the chronic stage when spongiosis is very minimal and the other features appear more dominant.. TIA.

Many thanks for this Dr Singh, very helpful. Could I please ask a question relating to melanocytes. They have a clear cytoplasm and this is how I generally first spot them in the basal layer. However, the difficulty I am encountering is distinguishing melanocytes from basal keratinocytes which undergo vacuolar degeneration in interface dermatitides. Is it fairly easy to distinguish one from the other? I don't know if I'm missing something obvious here. Thanks.

[@rajendrasingh-oo2fw]

If you see a nucleus and a halo around it, that is a keratinocyte and if you see the nucleus, cytoplasm around it and the halo outside, that is a melanocyte

[@bevin7]

Thanks Dr Singh, that's very helpful.
