  • Title: Lacrimal gland pleomorphic adenoma with extensive necrosis.
    Author: O'Rourke MA, McKelvie PA, Angel CM, McNab AA.
    Journal: Orbit; 2022 Jun; 41(3):378-381. PubMed ID: 33402001.
    Abstract:
    Lacrimal gland pleomorphic adenomas (LGPA) are benign mixed tumors. Diagnosis is based on clinical and radiological findings which usually prompts complete excision of the lesion to minimise recurrence and a cumulative risk of malignant transformation. Necrosis in pleomorphic adenoma has been rarely reported in salivary gland PA, either spontaneously or due to iatrogenic interventions. Necrosis is suggestive of a malignant process and makes interpretation of histology specimens difficult. A 23 year old woman, while awaiting biopsy for a mass in the left lacrimal gland, which had been symptomatic for only several months, presented with acute pain and swelling of the left lateral lid. An incisional biopsy showed an inflamed lacrimal gland with focal necrosis and atypia of adjacent cytology and gland architecture. Subsequent excisional biopsy confirmed an LGPA with some inflammation but no necrosis. Necrosis may occur as an atypical presentation in LGPA.
