Dental Update – November 2002 Abstract: Lichen planus is a relatively common, often clinically distinctive, mucocutaneous condition with an uncertain aetiology. One variant of lichen planus is the so-called ‘lichenoid drug eruption’. In contrast to idiopathic lichen planus, lichenoid drug eruptions, where practicable, may be managed by substitution of the offending drug. The dental clinician is...

Lichenoid drug eruptions can mimic idiopathic lichen planus and other dermatoses. The list of drugs that can cause them is long and growing steadily. Although cutaneous side effects of antipsychotics are rare, various cutaneous manifestations have been reported in association with olanzapine. We present the case of a patient who developed an atypical lichenoid eruption due to olanzapine. A revi...

This off-center fold case depicts the difficult differential diagnosis for benign lichenoid keratosis. It is challenging to diagnosis this benign lesion through clinical exam, dermoscopy, and even dermatopathology. Given its similar appearance to regressed melanoma, it is important to be cognizant of both and up to date on the dermatopathology clues.

Pseudonests or pseudomelanocytic nests represent aggregates of cells and cell fragments, including keratinocytes, macrophages, lymphocytes, and occasional melanocytes. Pseudomelanocytic nests in the setting of lichenoid inflammation can mimic atypical melanocytic proliferations. Several reports documented nonspecific staining of pseudonests with melanoma antigen recognized by T cells-1/Melan-A,...
