Bilateral enucleation due to multi-bacterial fulminant endogenous panophthalmitis. / Enucleación bilateral por panoftalmitis endógena polimicrobiana fulminante.

The case is presented of a 62 year-old woman with a rapid, progressive bilateral decrease in visual acuity and panuveitis with orbital cellulitis. She was also in poor general condition, with emesis and fever. Septicaemia due to Klebsiella pneumoniae and bilateral endogenous panophthalmitis were diagnosed. The ocular infection quickly progressed to sclerokeratitis and bilateral perforation despite broad spectrum systemic antibiotic management, and eventually the patient required bilateral enucleation. Microbiological cultures of the surgical pieces identified Klebsiella pneumoniae and Candida magnoliae. To our knowledge, this is the third published case that required bilateral enucleation or evisceration due to endogenous panophthalmitis, and the first case of endogenous ocular infection caused by Candida magnoliae.

Malignant transformation of a conjunctival keratoacanthoma requiring enucleation.

PURPOSE: We report a rare case of rapid transformation of a conjunctival keratoacanthoma (KA) into a highly aggressive squamous cell carcinoma requiring enucleation. To our knowledge, this is the second such case reported in the literature. METHODS: Case report. RESULTS: A 73-year-old man presented with a recurrent conjunctival lesion in the right eye. A slit lamp examination revealed a hyperkeratotic lesion in the limbar conjunctiva adhered to deep planes but with no ocular involvement. An incisional biopsy was performed because an area of scleromalacia was observed underlying the lesion. Histological findings were consistent with conjunctival KA. One week later, a raised lesion was observed invading the anterior chamber. Histological examination of another excisional biopsy specimen indicated conjunctival squamous cell carcinoma. The right eye was enucleated. Histological analysis confirmed intraocular tumor invasion. Complete clinical remission was observed over one year of follow up. CONCLUSIONS: Although conjunctival keratoacanthoma is normally benign, it is important to correctly differentiate between KA and squamous cell carcinoma, and closely monitor the eye after surgery because of the rare possibility of recurrence or conversion to squamous cell carcinoma. Immunohistochemistry could help in the diagnosis and management of dubious cases.

Resolution of conjunctival melanoma with topical interferon alpha 2b in a patient with mitomycin C intolerance. / Resolución de un melanoma conjuntival con interferón tópico alfa 2b en un paciente con intolerancia a la mitomicina C.

OBJECTIVE: To describe the clinical and histological resolution of a case of an inexcisable conjunctival melanoma using topical interferon alpha 2b (INFα2b) in a patient with mitomycin C (MMC) intolerance. CASE REPORT: Conjunctival melanoma is a rare, but potentially sight- and life-threatening, tumour. In cases of multiple lesions, or when surgical excision is not possible, topical combination chemotherapy with MMC and INFα2b has been described as first line therapy. The case is presented of a 77 year-old woman with a multifocal conjunctival in situ melanoma, who was intolerant to initial treatment with MMC and was switched to long-term INFα2b therapy, with a good outcome. CONCLUSIONS: When topical MMC is given as chemotherapy treatment for primary acquired melanosis with atypia or in situ melanoma is not well tolerated, switching to INFα2b seems to be a good option. This approach could replace surgical management of pigmented tumours, especially the larger ones, with potential benefits that include less dependence on surgical margins. This report prompts a need for prospective studies designed to examine the role of INFα2b as primary treatment for heavily pigmented conjunctival tumours avoiding the ocular surface toxicity caused by MMC.
