Basal Cell Carcinoma in Lacrimal Sac: An Exceptional Histopathological Finding

The authors report a case of a 49-year-old patient who presented with affection in the lacrimal sac. He had undergone multiple dacryocystorhinostomy surgeries, yet his symptoms failed to improve. However, histopathological examination revealed an unusual diagnosis: basal cell carcinoma. This is a completely atypical discovery and is rarely described in the literature in the lacrimal sac. The fact that this unusual location together with its difficult diagnosis given the similarity to the symptoms of a lacrimal duct obstruction makes this a particularly noteworthy case.
