Case Number : Case 2017 - 28 Feb 2018 Posted By: Uma Sundram

Epidermal atrophy, hydropic degeneration of the basal cells, upper dermal edema and lichenoid infiltrate all point towards LSA. Clinical features are also supportive.

Folliculotropic MF is often a solitary lesion. Syringotropism is also usually observed. 

A valid point Vincenzo. But epidermotropism has been described in lesions of LSA

We struggled with this one a little bit. The deep infiltrate was unusual for LSA (or LS, since sometimes we don't see atrophy) although I agree a lot of the other features of LSA are present. The presence of adnexotropism caused some concern for connective tissue disease. We eventually came down on (perhaps) LS/morphea overlap syndrome, with request to look out for other features of connective tissue disease upon follow up (i.e., if the patient has new lesions, these should be biopsied so we understand the disease process better). Agree with Anil that epidermotropism has been described in LS.

Can this be lichen striatus?
