Mucinous carcinoma: a translucent blue papule on an 89-year-old man

An 89-year-old man with no significant medical history presented with a slow-growing, asymptomatic translucent blue mass noticed 1 year prior to evaluation. Review of symptoms was negative for constitutional symptoms, gastrointestinal (GI) disturbance, and visual complaints. Physical evaluation revealed a 4-mm firm light blue translucent papule on the left medial canthus (Figure 1). No cervical or axillary adenopathy was present. No further lesions were identified during full body skin examination, including chest wall masses. A diagnostic study was performed and stained with hematoxylin-eosin (Figure 2) and periodic acid-Schiff (Figure 3).
