An 18-year-old otherwise healthy female presented with a 1-month history of an enlarging and mildly pruritic lesion on her face.
She had noted the presence of clear material oozing out when she squeezed the area. The physical examination revealed a 15-
mm pink plaque on her left upper cutaneous cutaneo lip, with slight accentuation around the hair follicles (Fig 1, A). The rest of her
cutaneous examination was normal. An incisional biopsy specimen revealed follicular structures filled with mucin (Fig 1, B),
highlighted by a colloidal iron stain (Fig 1, C ) and a mild lymphocytic follicular infiltrate. No large or atypical lymphocytes were
seen
