AIMS: To report the characteristics and management for patients with palpebral pleomorphic adenoma of the lacrimal gland.
METHODS: The records for patients with palpebral pleomorphic adenoma seen at Moorfields Eye Hospital between 1978 and 2019 were reviewed for demographics, presentation, imaging, histopathology, management, and outcome.
RESULTS: Forty-three patients (25 male; 58%) with palpebral pleomorphic adenoma were identified, presenting at a mean age of 46 years (median 46.4 years; range 24-81 years) with symptoms for an average of 31 months (median 18.0 months; range 1 month to 17 years). The commonest symptom was a painless upper lid lump (37 patients; 86%), although 4 patients (9%) had a localized ache, and 1 (2%) had episodic epiphora. A moderately-mobile, firm round mass (like a "chick-pea") was readily palpable in 39/43 (91%) patients, and significant ptosis and upper lid swelling was noted in 6 cases (14%). Imaging was reviewed in 35 patients, 28 (80%) having a well-defined homogeneous mass in front of the orbital rim, on the anterior pole of the lacrimal gland. With the exception of 8 tumors removed from the actual palpebral lobe using a conjunctival incision, all others were excised intact through an upper eyelid skin-crease incision. Histopathology confirmed an intact pseudocapsule in 39/43 (91%) and 10 (23%) had a mild chronic lymphocytic inflammation within the tumor and/or neighboring lacrimal gland. There were no tumor recurrences at an average follow-up of 40 months (median 9.1; range 2 weeks to 230 years).
CONCLUSION: Most palpebral pleomorphic adenomas are discovered as an upper lid lump and a few first become manifest as upper lid swelling with ptosis. To avoid inadvertent incisional biopsy, they should be recognized preoperatively-especially as most are readily palpable as a hard lump superotemporally, often freely mobile in the suborbicularis plane (anterior to the tarsus and main lacrimal gland). Excision, generally easiest through a transcutaneous route, was judged intact in all cases and confirmed in 91% of histological reports, with no recurrent tumors.
