A 13-year-old boy with typical peeling skin syndrome (PSS) is described. The clinical picture corresponded to the inflammatory variant of PSS (type B). In addition, the patient had gross and microscopic hair anomalies such as trichorrhexis invaginata-like changes, irregular hair shaft torsions and moniliform hair shaft diameter reductions. The observed dysmorphic hair changes are discussed and interpreted as being an integral component of the dermatosis in this case. To the best of our knowledge, such hair anomalies have not yet been described in PSS.

A patient with severe ichthyosiform erythroderma and lichenoid histological changes is presented. We discuss the clinical and histological differential diagnosis, including lupus erythematosus, lichenoid drug eruption, lichen planus, graft-versus-host disease, lymphoma, keratosis lichenoides chronica, Netherton's syndrome and ichthyosiform erythroderma. None of these is consistent with the features in our case, which may represent either a hitherto unreported form of ichthyosiform erythroderma or possibly a new entity.
