A 51-year-old male patient presented to the outpatient clinic with a painless nodule near the right lower eyelid. The mass had grown slowly over the past 3 years, and measured 0.9×0.7 cm during examination (). The lesion appeared benign in clinical examination, and under local anesthesia, the patient underwent a 3-mm-margin elliptical excision and primary closure. Histologic study of this first specimen revealed epithelial cell islands floating in a mucin lake, with the final diagnosis being mucinous carcinoma. The epithelial component showed a solid and cribriform growth pattern and the tumor cells revealed moderate nuclear atypia and a mitotic aspect. Additional immunostaining study revealed that the tumor cells were immunopositive for cytokeratins (CK)-7 and negative for CK-20 with 10% Ki-67 positivity in the active area (). We performed re-excision of the surgical site with an additional 3-mm margin, which was free of malignant histology. The possibility of a metastatic primary mucinous carcinoma (e.g., breast or gastrointestinal tract) could not be completely ruled out, but a systemic evaluation by positron emission tomography-computed tomography revealed no other suspected site of malignancy. During a close follow-up over 2 years, the patient did not experience any postoperative complication or recurrence ().
A 65-year-old male with a right lower eyelid mass had history of adenocarcinoma of the left orbit, status post radiation therapy, followed by left orbital exenteration, 12 years prior to presentation at MDACC. An MRI of the orbit, face, and neck performed at MDACC demonstrated a thickened enhancing lesion adjacent to the right nasolacrimal duct measuring 4.1 × 1.0 cm () which extends from the medial canthus to the lateral inferior periorbital soft tissue. In addition, mildly thickened soft tissue enhancement along the left premolar soft tissues suspicious for recurrent disease was reported. Prior positron emission tomography (PET)/CT scan and MRI of the brain performed in an outside facility failed to demonstrate second primary or metastatic disease. Wide local excision of the right lower eyelid and cheek mass was performed with intraoperative margin assessment showing positive margins. Microscopically, cords of histiocytoid cells arising from eccrine glands were identified infiltrating skeletal muscle and orbit with extensive perineural invasion (). Surgical margins were positive. Five months after completion of radiation therapy, the patient noted a new right upper eyelid nodule. A CT scan of head and neck reveals local right retroorbital recurrence and left neck adenopathy. A more radical surgery for the right orbit was avoided due to the cancer demonstrating a very slow growth pattern, and it would render him totally blind.\nFour years of documented follow-up (until January 2019, when the patient was last contacted at MDACC) after the first surgery done for the lower eyelid mass, he was still alive. Currently, the patient is being seen at an outside facility with his only eye globe intact. He has had slowly progressive distant lymph node metastatic disease for which standard treatments have not been offered, and he is not keen to enroll in clinical trials.
