From Seed to Spread: Lacrimal Sac Squamous Cell Carcinoma Blossoming Into Orbital Chaos.

Non-cutaneous squamous cell carcinoma (ncSCC) is a rare malignancy, especially involving the orbital and lacrimal apparatus. Hereby, we present a case of recurrence of squamous cell carcinoma (SCC) in the left orbit after excision of lacrimal sac SCC and radiotherapy. She presented with acute painful visual impairment with a frontal headache, with imaging showing medial extraconal and intraconal mass. After confirmation of SCC from the biopsy, modified enucleation was done. However, the patient had a recurrence of SCC, and further debulking was performed with palliative measures. Noteworthy, ncSCC is a rare malignancy with an aggressive nature. Orbital SCC has the worst prognosis compared to conjunctiva or lacrimal sac SCC. Surgery remained the mainstay for higher survival, but chemotherapy and radiotherapy were not associated with a better prognosis, yet there is a lack of data regarding recurrence and its management. In conclusion, ncSCC is a rare and challenging disease that requires timely intervention with multiple disciplinary care, especially when it is spread from the lacrimal sac to the orbital.
