Imrani K, Oubaddi T, Jerguigue H, Latib R, Omor Y. Adenoid cystic carcinoma of the lacrimal sac: A case report. Int J Case Rep Images 2021;12:101273Z01KI2021.ABSTRACT
Introduction: Adenoid cystic carcinoma (ACC) of the lacrimal sac is a rare entity characterized by poor prognosis, because of the high rate of local recurrence and metastasis after treatment.
Case Report: A 45-year-old male patient was seen at our institution for epiphora, pain, and swelling of the internal angle of the left eye evolving for three months. The clinical examination revealed a fixed mass above the medial canthus of the left eye with blood discharge from the lacrimal punctum at the pressure of the mass. Orbital magnetic resonance imaging (MRI) showed a left lacrimal sac mass. Incisional biopsy disclosed adenoid cystic carcinoma.
Conclusion: This is a rare case of lacrimal sac malignant tumor. Adenoid cystic carcinoma can develop in the salivary or lacrimal glands; however, its occurrence in the lacrimal drainage apparatus is extremely rare. Imaging plays a key role in the diagnosis, thanks to computed tomography (CT) scan and magnetic resonance imaging (MRI) which allow a detailed analysis of the local and distant extension, as well as in post-treatment follow-up.
Keywords: Adenoid carcinoma, Lacrimal sac, MRI
