ABSTRACT
Purpose: This case report aims to present a rare instance of conjunctival melanoma in a 5-year-old patient and contribute to the limited body of knowledge on pediatric conjunctival melanoma. The purpose is to understand the characteristics, diagnosis, and management of this uncommon malignancy in young individuals. Observations: The case describes a 5-year-old female with a progressively growing pigmented conjunctival lesion. The lesion was observed to be located on the temporal conjunctiva of the right eye and displayed distinctive features, including feeder vessels. Imaging revealed specific dimensions of the lesion and ruled out deeper invasions. Histopathological examination revealed architectural and cytologic atypia, positive immunohistochemical staining for HMB-45, and a Ki67 proliferation index of 20 %, confirming the diagnosis of conjunctival melanoma. Conclusions: Conjunctival melanoma, an uncommon malignancy even more so in pediatric patients, typically presents with pigmented growths and feeder vessels. This case underscores the need for thorough diagnosis and early intervention, as conjunctival melanoma can lead to devastating outcomes. The rarity of such cases limits our understanding of their etiology and progression. This case contributes to the literature on pediatric conjunctival melanoma and reinforces the importance of vigilance in detecting and managing ocular pigmented lesions in children.
ABSTRACT
OBJECTIVE: Small donors have long been considered a potential source of organs for simultaneous pancreas-kidney transplantation (SPK) and pancreas transplantation alone (PTA). Our aim was to analyze our experience with SPK and PTA using small donors weighing <28 kg. PATIENTS AND METHODS: Between September 2006 and October 2008, we performed 68 SPK, 3 PTA, and 3 pancreas after kidney transplantations (PAK). All recipients were adults with type 1 diabetes mellitus, including 8 who received small donor organs (<28 kg): 6 SPK and 2 PTA. We used 3 graft combinations for SPK: pancreas and single kidney; pancreas and en bloc kidneys; and en bloc dual kidney-pancreas. In contrast, we used conventional grafts for PTA. Mean weight among donors was 20.82 kg (range, 9.6-27 kg). RESULTS: We observed neither delayed graft function nor mortality. At a follow-up of approximately 281 days, all patients were free of insulin and dialysis treatments. CONCLUSIONS: Kidneys and pancreas from donors weighing <28 kg can be used in adult type 1 diabetic patients with excellent results. These small pediatric donors enabled us to enlarge the number of transplantations by 10.81%.
