Primary Amyloidosis Localized to the Conjunctiva

PURPOSE: To report a case of primary amyloidosis localized to the conjunctiva. CASE SUMMARY: A 19-year-old male with a conjunctival mass and foreign body sensations in the right eye transferred from another hospital. A 0.5 × 2.5 cm reddish mass was present in the medial canthus of the right conjunctiva with no other clinically specific signs. Surgical excisional biopsy was performed. Histological examination showed amyloid deposition. There was no other orbital involvement apart from the conjunctiva. Abnormalities were not found in the systemic examination. CONCLUSIONS: We report a case of primary amyloidosis localized to the conjunctiva.

Surgical amniotic membrane transplantation after conjunctival and limbal tumor excision / Transplante de membrane amniótica após excisão de tumor limbar e conjuntival

ABSTRACT Purpose: To evaluate the clinical results of patients treated by amniotic membrane transplantation (AMT) following excision of conjunctival and limbal tumors. Methods: A total of 14 eyes of 14 patients who underwent AMT after total lesion-free tumor excision and perilesional cryotherapy were evaluated. Results: The excised tumors comprised 7 conjunctival intraepithelial neoplasia, 5 conjunctival nevus, 1 primary acquired melanosis, and 1 squamous cell carcinoma. Limbus was involved in 10 cases, whereas cornea was involved in 6 cases. The average measurement of the tumor base was 14.8 mm (range 6-20 mm, SD 16 mm). The mean follow-up time period was 17.5 months (range 6 -60 months, SD 20 months). Complete healing occurred in eight eyes, but limbal cell deficiency developed in two eyes. Four cases had recurrence and were treated with the same surgical and medical procedures; during follow-up after recurrence, superficial peripheral vascularization and corneal scar were noted to have developed. Conclusions: AMT was effective for reconstruction of tissue defect after excision and cryotherapy of limbal and conjunctival tumors. In most of these cases, complete healing was achieved with a smooth, stable, and translucent surface.

RESUMO Objetivo: Avaliar os resultados clínicos de pacientes tratados com transplante de membrana amniótica (TMA) após a excisão de tumores conjuntival e limbar. Métodos: Foram avaliados 14 olhos de 14 pacientes submetidos a transplante de membrana amniótica após excisão total de tumor e crioterapia perilesional. Resultados: Os tumores que foram excisados podem ser classificados como neoplasia intraepitelial conjuntival em 7, nevus conjuntival em 5, melanose adquirida primária e carcinoma espinocelular em 1 caso cada. O limbo foi envolvido em 10 casos e a córnea foi envolvida em 6 casos. A medida média da base do tumor foi de 14,8 mm (6-20, DP 16). O tempo médio de seguimento foi de 17,5 meses (6-60, DP 20). A cicatrização completa ocorreu em 8 olhos e deficiência de células limbares ocorreu em 2 olhos. A recorrência foi diagnosticada em 4 casos e tratada com o mesmo procedimento cirúrgico e médico e, após essa recorrência, a vascularização periférica superficial e a cicatriz corneana desenvolveram-se em 4 casos durante o seguimento. Conclusões: O transplante de membrana amniótica é um método eficaz para a reconstrução do defeito do tecido após a excisão de tumores limbares e conjuntivais com a combinação de crioterapia. Na maioria destes casos, a cicatrização completa pode ser conseguida com uma superfície lisa, estável e transparente.

Conjunctival Myxoma-A Case Report

Ocular myxomas are rare neoplasms. We report a case of conjunctival myxoma in a 33-year-old male. Clinically, it was diagnosed as a conjunctival cyst. Histopathological findings revealed spindle, and fusiform cells in loose myxoid stroma with cystic change. There were no systemic abnormalities detected.
