Aim: The goal of this case report is to describe the dermatologic and conjunctival findings in a case of bilateral diffuse uveal melanocytic proliferation (BDUMP), a paraneoplastic syndrome usually associated with gynecologic cancers. There is little information about other dermatologic melanocytic findings in these patients.
Methods: Histologic and fluorescent in situ hybridization (FISH) analysis of three separate skin biopsies, one of which was separated by 21 months from the others, were performed in a 71-year-old patient with BDUMP to assess for histologic and chromosomal abnormality. Conjunctival histologic evaluation was also done.
Results: Dermal melanocytic proliferation was seen in each specimen. The cells were spindle type with mitotic activity. FISH analysis showed a normal copy of chromosomes. The conjunctival sample also showed normal FISH analysis.
Conclusion: BDUMP is associated with multifocal dermal and conjunctival melanocytic proliferation.
