Asymptomatic Swelling of a Man's Ear

Arch Dermatol. 1998;134(12):1627-1632. doi:

A 40-year-old man presented with a 1-week history of painless swelling of the left ear. He denied any history of trauma. Physical examination revealed a 3 × 3-cm fluctuant, nontender, cystic swelling in the scaphoid fossa of the left auricle (Figure 1, arrows). The lesion was incised and drained. Cultures of the straw-colored, clear fluid were negative for bacteria. Within 3 days, the swelling recurred. A biopsy specimen was obtained (Figure 2, Figure 3, and Figure 4).
