Trilateral retinoblastoma with unilateral eye involvement.

Retinoblastomas (RB) are the main forms of intraocular tumor in childhood, with a worldwide incidence of 1 case per 15,000 to 20,000 live births. Trilateral RB (RBT) is a rare combination of unilateral or bilateral RB with a midline intracranial neoplasm of neuroblastic origin, usually found in the pineal region or the suprasellar region, presenting variable incidence of 0.5% up to 6% among patients with RB.

Conjunctival follicular lymphoma after treatment for invasive squamous cell carcinoma.

Backgrounds/aims: The authors describe the case of a 79-year-old Caucasian woman who presented an ocular adnexal lesion as the first clinical manifestation of a systemic follicular lymphoma, highlighting the clinicopathological features of this rare entity and its potential to be misdiagnosed as marginal zone lymphoma of the mucosa-associated lymphoid tissue.

Methods: Conjunctival impression cytology was performed for a rapid initial diagnosis of lymphoma, and subsequent histopathological and immunohistochemical studies were carried out for its confirmation and to identify the best therapeutic regimen.

Results: After the initial presentation and diagnosis, she was submitted to complete clinical evaluation; confluent retroperitoneal lymphadenopathy was detected through abdominal computed tomography, characterizing clinical stage III.

Amelanotic corneally displaced malignant conjunctival melanoma: a case report evaluated with impression cytology.

Here we describe the case of a 65-year-old Caucasian female who presented with an amelanotic malignant conjunctival melanoma and highlight the clinical and pathological features of this rare entity that displayed exclusive corneal invasive growth without evidence of conjunctival tumors other than primary acquired melanosis. Impression cytology aided in the initial diagnosis. The patient underwent surgical treatment.

Phacoemulsification and foldable acrylic IOL implantation in children with treated retinoblastoma.

Purpose: To study the results of cataract surgery in children with radiation-induced cataract after treatment for retinoblastoma.

Methods: Retrospective interventional case series. Six consecutive patients diagnosed with secondary cataracts due to radiation therapy for retinoblastoma.

Primary transpupillary thermotherapy for small choroidal melanoma.

Background: The treatment of small choroidal melanoma is controversial. Thermal laser-induced treatment is utilized by some centers but there is still sparse literature about the subject, mainly with short-term follow-up time. The efficacy of transpupillary thermotherapy (TTT) for the treatment of small choroidal melanomas was evaluated.
