Basal cell carcinoma with mucin production in the left nasal bridge of a 59 year old man, presenting as a presumptive lacrimal cyst. Because of the location, immunohistochemical stains were needed to exclude eccrine tumors and salivary gland type tumors. A. A spheroidal, well circumscribed mass shows intertwining nests (green arrow), isles with cribriforming (yellow arrows), and large acini (cyan arrows), with good circumscription. B. Round to ovoid nuclei show > 4:1 nuclear size variation in some adjacent pairs (black arrows) and occasional pyknotic nuclei (green arrows). Lumens show mucinous material with vacuoles (yellow arrows); the color argues against adenoid cystic carcinoma, but certainty in that respect could not be maintained without immunostains. Note lining up of nuclei suggestive of palisades (blue arrows). C. Nuclei are P63 positive, not shown are the negative stains for SOX10, CK7, and CD117. | |||
