Optimal treatment for pseudocyst of the ear involves removal of the anterior cartilaginous leaflet of the pseudocyst with repositioning of the overlying flap of skin. This results in a normal-appearing auricle with minimal scarring or recurrence of the pseudocyst.

A 68-year-old man presented with an 8-month history of a pruritic zosteriform eruption of the left trunk and thigh areas, corresponding roughly to the T-11 and L-4 dermatomes. He was otherwise healthy with the exception of hypertension. Medications included hydrochlorothiazide, metoprolol, and captopril, none of which was temporally related to the onset of the eruption. No prior trauma or dermatologic history was obtained.Physical examination revealed a collection of scaling polygonal papules limited to a serpiginous or zosteriform pattern (Figs 1 and 2). Mucous membranes were normal and the nails revealed longitudinal ridging and pitting. A punch biopsy was performed;representative sections are shown in Figs 3 and 4.
