A 58-year-old woman presented with bilateral facial eruptions of 3 weeks duration composed of erythematosus papules in a linear distribution. The pathological features demonstrated a dense dermal and follicular infiltrate of many medium- to large-sized atypical CD30-positive lymphoid cells. The rash resolved rapidly after discontinuation of her medication 1 week later and did not recur. This case highlights the importance of clinicopathological correlation. *Department of Dermatology, Mackay Memorial Hospital, Taipei, Taiwan; and †Department of Medicine, Mackay Medical College, New Taipei City, Taiwan.
