Abstract

Insights

This case report details a rare instance of multiple, bilateral choroidal tumors caused by small cell neuroendocrine carcinoma of unknown primary. This unusual intraocular involvement highlights the importance of comprehensive oncologic evaluation.

Area of Science:

  • Ophthalmology
  • Oncology
  • Pathology

Background:

  • Small cell neuroendocrine carcinoma (SCNEC) is an aggressive malignancy.
  • Intraocular metastases are rare, with choroidal involvement being particularly uncommon.
  • Unknown primary tumors pose diagnostic challenges.

Purpose of the Study:

  • To report a unique case of bilateral choroidal tumors secondary to poorly differentiated SCNEC of unknown primary.
  • To contribute to the literature on rare intraocular manifestations of SCNEC.

Main Methods:

  • Presentation of a clinical case of a 30-year-old female with multiple and bilateral choroidal tumors.
  • Comprehensive oncologic work-up including physical examination, laboratory tests, and radiographic studies.
  • Review of existing literature on intraocular SCNEC.

Main Results:

  • The patient presented with disseminated disease.
  • Despite extensive investigations, the primary tumor site remained unidentified.
  • The patient succumbed to the disease six months post-diagnosis.

Conclusions:

  • This is the first reported case of intraocular involvement from poorly differentiated SCNEC of unknown primary.
  • The case underscores the potential for SCNEC to metastasize to the choroid.
  • Further research is needed to understand the mechanisms and outcomes of SCNEC in the eye.
