RESUMEN
Purpose: The term melanocytoma was recently proposed for intermediate-stage melanocytic lesions with specific histopathologic and molecular genetic features. Prior studies have demonstrated a heightened potential for these intermediate lesions to spread to regional lymph nodes, with decreased likelihood for distant spread, when compared to melanomas. Observations: Herein we present a case of a 28-year-old male who presented with a recurrent right lower eyelid margin combined cutaneous and palpebral conjunctival pigmented lesion, ultimately classified as a melanocytoma, to highlight this new nomenclature, characteristic histopathologic and genetic findings, and prognostic implications. Conclusions: Ophthalmologists should be aware of this new cutaneous histopathologic classification system and apply to the periorbital region to improve melanocytic lesion management and surveillance.
RESUMEN
Purpose: Foreign body reaction to non-absorbable alloplastic orbital implants utilized for bony reconstruction are infrequently documented in the literature. We present the workup and surgical management of a giant cystic mass encapsulating a patient's alloplastic orbital implant, which was ultimately deemed to be a result of foreign body reaction. Observations: A 41-year-old male patient with distant history of a right orbital floor fracture had undergone repair with the placement of a nylon foil implant. The patient presented twenty years later with progressive ipsilateral globe proptosis and was found to have a giant inferior orbital cyst. Surgical exploration and removal of the implant and capsule were performed. Histopathology confirmed a delayed foreign body reaction around the patient's alloplastic implant. Conclusions: Alloplastic implants may result foreign body reaction and cyst encapsulation as a delayed complication.
