Extraconal Orbital Soft Tissue Metastasis Secondary to Prostate Cancer: An Unusual Presentation

Sakshi Kapur, Han Xiao

Abstract


Prostate cancer is mostly known to metastasize to the bony skeleton. Soft tissue metastasis involving visceral organs such as the liver, lung and brain are unusual and rare manifestations of this cancer. However, with better treatment modalities and increased survival, the incidence of these unusual presentations, seems to have risen in the last few years. Prostate cancer is rarely known to metastasize to the orbit. Although cases of bony metastasis involving the orbit have been reported, soft tissue metastasis involving the orbit is a very rare presentation. Most soft tissue metastasis to the orbit involves the uveal tract, with prostate cancer being the most common primary cancer to metastasize to the iris (uveal tract). Our paper highlights a case of extraconal orbital soft tissue metastasis secondary to prostate cancer, an extremely rare presentation. Patient was started on combined androgen blockade therapy. Three-month repeat MRI orbit showed that the extraconal orbital mass had decreased in size significantly. His clinical symptoms have resolved at the time of this report. To our knowledge, this is the first reported case of its kind.
