Leiomyoma - Ciliary Body Tumor. A Case Report.

AIM: To demonstrate a rare case of ciliary body leiomyoma in our patient Case report: A 72-year-old female reported to our clinic for a preventive examination, upon which we found a dome-shaped grey-brownish mass on the retinal periphery. After completing gonioscopic and ultrasound examinations, we referred the patient to a specialist facility. Due to a finding of suspicious malignant melanoma, we completed the MRI scan and recommended enucleation of the eyeball. A histopathological examination showed a leiomyoma of the ciliary body. CONCLUSION: The aim of this case report is to demonstrate the difficulty of intraocular leiomyoma diagnosis. Only immunohistochemical examination differentiated the tumor from malignant melanoma and determined the diagnosis of ciliary body leiomyoma. Perhaps because of the extreme rarity of this type of tumor, we often neglect to consider a diagnosis of leiomyoma.

Leukemic infiltration of the ciliary body in a child with T-cell acute lymphoblastic leukemia.

A 14-year-old boy presented after 2 months of vision loss, redness, and pain in the right eye, initially treated as anterior uveitis with topical corticosteroids. He had a 1-year history of T-cell acute lymphoblastic leukemia, which had been in remission for 6 months. On examination, visual acuity in the right eye was light perception, with 4+ anterior chamber cells, pupillary membrane, and an intumescent cataract. Ultrasound biomicroscopy (UBM) revealed a ciliary body mass and capsular bag rupture. After consultation with his oncologist, he received 10 radiotherapy sessions. At 1 month, UBM showed resolution of the mass. After 1 year of remission, the patient underwent pars plana vitrectomy, pupillary membranectomy, and placement of a scleral-fixated intraocular lens. Thirty months after surgery, visual acuity was 20/25. Leukemic infiltration of the ciliary body is a rare manifestation of the disease that is often misdiagnosed as uveitis.

Local resection via partial lamellar sclerouvectomy for ciliary body tumors - a case series.

BACKGROUND: Ciliary body tumor is extremely rare and treatment is challenging. The aim of this study is to present our experience in treating this rare entity, especially large tumors with more than 5 clock hours of involvement, and to evaluate the surgical outcomes and complications of local resection via partial lamellar sclerouvectomy in four cases of ciliary body tumors in China. METHODS: Four patients with ciliary body tumors underwent partial lamellar sclerouvectomy between October 2019 and April 2023 in Shanghai General Hospital, China. Tumor features, histopathologic findings, complications, visual acuity, and surgical outcomes were reviewed at a mean follow-up of 20.8 months. RESULTS: Four patients with a mean age of 31.8 years were included in this study. The histopathological diagnosis was adenoma of non-pigmented ciliary epithelium (ANPCE), schwannoma, and multiple ciliary body pigment epithelial cysts. The mean largest tumor base diameter was 6.00 mm (range: 2.00-10.00) and the mean tumor thickness was 3.50 mm (range: 2.00-5.00). Preoperative complications included cataract in 3 (75%) eyes, lens dislocation in 2 (50%), and secondary glaucoma in 1 (25%). Temporary ocular hypotonia was observed in one case and no other postoperative complications were observed. At a mean follow-up of 20.8 months, the best corrected visual acuity increased in 3 eyes and was stable in 1 eye. Tumor recurrence was absent in all eyes. All patients were alive at the end of follow-up. CONCLUSIONS: Local tumor resection via PLSU is useful in the treatment of ciliary body tumors, including large tumors occupying more than five clock hours of pars plicata. Surgery-related complications were manageable with adequate preoperative assessment and careful operation during surgery.

Anterior plaque brachytherapy placement for treatment of iris and iridociliary melanomas - Surgical procedure and institutional experience.

Surgical placement of eye plaque brachytherapy (EPB) is the standard of care for the treatment of uveal melanomas, including iris/iridociliary melanomas. However, unique challenges exist in anterior EPB placement. Here, we describe a surgical technique for anterior EPB placement when placement requires plaque positioning onto the cornea. Blunt conjunctival peritomy exposes the sclera overlying the tumor. A "dummy" plaque is placed, with positioning confirmed by direct visualization. The amniotic membrane is draped across the cornea and anchored with the eyelet sutures, the plaque is placed overlying the membrane, the conjunctiva is closed over the plaque, and a temporary tarsorrhaphy is performed. One week later, the conjunctival incision is reopened for plaque/amniotic membrane removal. This technique was employed in the treatment of 12 iris/iridociliary melanomas at our institution, with no instances of corneal damage. In placing an anterior plaque, employing this technique allows appropriate cancer treatment while optimizing patient comfort and corneal integrity.

Intraocular schwannoma: case series of 28 patients and literature review.

PURPOSE: Intraocular schwannoma is a rare tumour, which is often misdiagnosed. We presented the demographics and clinical characteristics of patients with intraocular schwannoma. METHODS: Retrospective case series were collected between May 2005 and July 2021 in Beijing Tongren Hospital. RESULTS: A total of 28 patients were diagnosed with intraocular schwannoma on histopathological examination of surgical specimen. The median age was 39 years (range: 12-64). Fourteen patients were female and 14 were male. Among the all subjects, 21/28 patients (75.0%) presented as visual loss, and 3/28 patients (10.7%) had visual field loss. Intraocular schwannoma presented as nonpigmented mass in the ciliary body in 12/28 cases (42.9%), in the choroid in 9/28 cases (32.1%), and in ciliochoroid in 7/28 cases (25.0%). Intraocular schwannoma was often clinically misdiagnosed as uveal melanoma, which occurred in 16/28 patients (57.1%). Tumour excision with pars plana vitrectomy was performed for all included patients. Endoresection with lens removal was performed for tumours in the choroid, while transscleral resection was performed for tumours located in ciliary body or ciliochoroid. Increased light transmission was detected in 12/28 cases (42.9%). In the consecutive follow-up (median: 73 months, range: 7-193 months), no cases of recurrence or metastatic disease were detected. CONCLUSIONS: Intraocular schwannoma is a rare benign tumour. It usually presents as nonpigmented mass, which can easily be misdiagnosed as nonpigmented uveal melanoma.

Internal eye wall resection of uveal tumors: long-term evaluation / Ressecção em bloco de tumores uveais: avaliação de longo prazo

The authors report five cases of uveal tumors managed with internal eye wall resection and evaluate the long-term results. Patient age varied from 31 to 61 years. Four patients were female and one was male. Uveal tumors involved ciliary body and choroid in three patients and choroid alone in the other two. Histopathological examination demonstrated three uveal melanomas, one leiomyoma, and one meduloepithelioma. The largest tumor diameter ranged from 8 to 15 mm and tumor thickness from 5 to 11 mm. Follow-up of the patients was over a period of 6 to 23 years. Final visual acuity was 20/20 in 3 patients and 20/200 in one patient, and in the fifth patient, the affected eye was enucleated. No cases of metastatic disease or local recurrence of the tumor were observed, suggesting that internal eye wall resection is a valid alternative for the treatment of selected cases of uveal tumors.

Os autores relatam 5 casos que apresentavam tumores uveais e foram submetidos à remoção cirúrgica em bloco do tumor, avaliando resultados de acuidade visual, índice de retenção do globo ocular e de doença metastática. Quatro mulheres e um homem, com idade entre 31 e 61anos foram submetidos ao procedimento. O tumor envolvia corpo ciliar e coroide em três olhos e somente a coroide em dois. A histopatologia demonstrou que 3 tumores eram melanomas, um leiomioma e um meduloepitelioma. O maior diâmetro dos tumores foi entre 8 e 15 mm e a espessura entre 5 e 11 mm. O tempo de seguimento dos pacientes foi de 6 a 23 anos. A acuidade visual final foi de 20/20 em 3 olhos, 20/200 em outro e um olho foi enucleado. Não foram observados casos de doença metastática ou recorrência tumoral, sugerindo que a ressecção em bloco de tumores uveais é uma alternativa válida para o tratamento destes tumores em casos selecionados.

Aspectos psicológicos e qualidade de vida em pacientes com melanoma uveal durante o processo de tratamento por remoção do bulbo ocular / Psychological aspects and quality of life in uveal melanoma patients during the treatment process by ocular bulb remotion

OBJETIVO: Avaliar prospectivamente as repercussões emocionais no indivíduo com melanoma uveal e indicação cirúrgica em três momentos: diagnóstico e pré-cirúrgico, pós-cirúrgico e pós-cirúrgico tardio. MÉTODOS: Trata-se de estudo clínico-qualitativo, no qual se utilizaram os seguintes instrumentos: Inventário de Ansiedade Traço/Estado - IDATE; Inventário de Depressão Beck e o Questionário de Qualidade de Vida SF-36. RESULTADOS: Participaram do estudo, inicialmente, 20 pacientes, 13 homens e sete mulheres, com idade média de 52 anos e, num segundo momento, 16 estavam disponíveis. No momento pré-cirúrgico, o Estado de Ansiedade está aumentado em relação ao Traço. O índice de Depressão indica um estado mínimo a leve e a Qualidade de Vida revela que os aspectos físicos e emocionais são os mais afetados. No pós-cirúrgico de três meses, o Traço de Ansiedade está consideravelmente elevado, o índice de Depressão mostra um estado leve a grave e na Qualidade de Vida os aspectos mais atingidos são os físicos, sociais e emocionais, além da vitalidade e da saúde mental. No pós-cirúrgico de um ano, o Traço de Ansiedade se mantém semelhante ao da primeira avaliação, o Estado de Ansiedade diminui consideravelmente, a Depressão cai para um índice mínimo e a Qualidade de vida mostra a maioria dos aspectos equilibrados. CONCLUSÕES: Após três meses da cirurgia, os pacientes se mostram mais frágeis, com dificuldade de adaptação, com aumento do grau de depressão e ansiedade. Esse foi o pior período para os pacientes. Após um ano da cirurgia, mostram-se mais estruturados e com os aspectos de Qualidade de Vida mais equilibrados.

PURPOSE: To evaluate prospectively the emotional repercussions in the individual with uveal melanoma and surgical indication in three phases: diagnosis and preoperative, postsurgery and late postsurgery. METHODS: Clinical qualitative study based on the following instruments: STAI - State, Trait Anxiety Inventory; BDI - Beck Depression Inventory; Quality of Life Questionaire SF-36. RESULTS: The sample of this study consisted of 20 patients, 13 males and seven females, with average age of 52 years. Before surgery: the patients appear fragile and impacted by diagnosis and treatment. The state of depression indicates a minimum to light state. Anxiety has the state increased in relationship to Trait. Quality of Life has the emotional and physical aspects affected. Three months after surgery: the Depression shows to light to serious state. Anxiety has the state considerably increased. Quality of Life has most aspects affected: the physical, vitality, social, mental health and emotional aspects being the most affected. One year after surgery: the State of Anxiety decreases considerable. The Trait of Anxiety is maintained in most patients when compared to the first evaluation. Depression shows a minimum state. Quality of Life has most of its aspects balanced. CONCLUSION: After three months of surgery the patients appear more fragile with adaptation difficulty, Anxiety and Depression increasing. This period revealed to be the worst moment. One year after surgery, they appear more structured and with a more balanced Quality of Life.
