There has been no recurrence of his disease, and he remains in good health. Log on to our website www. The editors will decide as before whether to also publish it in a future paper issue. The primary cutaneous variant of ALCL usually presents as a solitary, cutaneous, or subcutaneous reddish violet lesion, which can be superficially ulcerated.
Case report A 39 year old man presented with a 4 week history of a progressive painless ulcerating nodule on the right upper eyelid, unresponsive to oral flucloxacillin.
He was systemically well and denied recent foreign travel or contact with animals. British journal of ophthalmology cover letter 17 mm diameter ulcer with rolled margins and serosanguinous exudate was evident over the right upper eyelid fig 1. His cornea, conjunctiva, and anterior chamber were normal, british journal of ophthalmology cover letter.
Systemic examination was unremarkable. Investigations including full blood count, british journal of ophthalmology cover letter, urea and electrolytes, bone and liver profile, immunoglobulins and electrophoresis, autoantibody screening, and Treponema antibody were normal or negative.
Tissue culture failed to demonstrate a bacterial, viral, or fungal Comment Figure 2 Histopathology from ulcer edge. There was no clinical, radiological, or bone marrow evidence of extracutaneous disease.
Histology of the biopsy taken from the lid ulcer margin showed epidermal necrosis associated with ulceration fig 2. The ulcer base showed haemorrhagic granulation tissue infiltrated by a mixture of lymphocytes, plasma cells, neutrophils, and eosinophils. There were also ill defined groups of large blast cells showing enlarged and pleomorphic nuclei and high mitotic activity.
The immunohistochemical staining showed these cells to be of T cell lymphoid lineage. Many of the large blast cells were CD30 positive but negative for ALK-1 protein. The features were of a CD30 positive anaplastic large cell lymphoma ALK negative.
Treatment options such as surgery and radiotherapy were discussed with the patient but as the lesion remained stable over a 10 day period, a conservative approach was agreed. A moderately potent topical corticosteroid mometasone furoate 0.
When followed up 8 weeks later the ulcer had completely healed without scarring fig 3. ALCL represents a group of large cell lymphomas. They consist of a proliferation of predominantly large lymphoid cells with strong expression of the cytokine receptor CD Most patients present with solitary, british journal of ophthalmology cover letter, asymptomatic nodules, which can be superficially ulcerated.
However, patients with disseminated skin disease may benefit from systemic polychemotherapy. The application of a moderate potent topical steroid might have contributed to the regression of the ulcer. We present a case of a primary cutaneous ALCL of the eyelid showing regression.
Ophthalmologists should be aware of this sometimes self regressing entity and an expectant policy might be indicated in nonprogressing tumours, thus avoiding potentially mutilating surgery or radiotherapy.

Clinicopathological study of four cases and review of the literature. Br J Dermatol ;—6. com PostScript rich and redundant blood supply of the choroid allowed some freedom in the choice of graft harvest site. This technique is simpler than time consuming retinal translocation and does therefore merit further investigation.
Choroidal translocation with a pedicle following excision of a type 1 choroidal neovascular membrane Excision of type 1 choroidal neovascular membranes CNVM in age related macular degeneration AMD have a poor visual outcome because of loss of retinal pigment epithelium RPE. Creating a free graft of these three british journal of ophthalmology cover letter detaches the choroid from its blood supply. Hence, restoration of these three layers to the subfoveal position while maintaining a connection to the adjacent choroidal blood supply is desirable.
Clinical examination and fluorescein fundus angiography FFA confirmed a type 1 subfoveal CNVM. Pars plana vitrectomy PPV and excision of the CNVM were performed as described previously. A retinotomy was formed temporal to the fovea and vertical scissors inserted into the subretinal space. The graft was manipulated to a subfoveal position.
The pedicle and graft were equally sized to maximally exploit the rich choroidal vasculature and maintain continuity to the choroidal circulation, british journal of ophthalmology cover letter.
We were unable to predetermine the position of choroidal vessels as indocyanine green angiography ICG was unavailable to us at the time of surgery.
Surprisingly, little bleeding occurred and was easily controlled by increasing the infusion height. The patient required two subsequent operations for a rhegmatogenous retinal detachment with grade B proliferative vitreoretinopathy.
The retina was flattened after inferior retinectomy and silicone oil insertion. At review 4 years following initial surgery her vision was CF with a central scotoma on Goldmann field testing. At 4 years following surgery there was no recurrence of the CNVM on FFA fig 1B and ICG angiography demonstrated that the graft and pedicle were vascularised fig 2. Comment Excision of type 1 CNVMs has a poor prognosis because of loss of RPE and atrophy of the choroid. Retinal translocation with strabismic surgery for the movement of the retina to healthy RPE is prolonged and hazardous.

We thought that the Intravitreal injections of triamcinolone acetonide have increasingly been performed as treatment for intraocular diseases with intraretinal oedema and with subfoveal fluid accumulation, such as diffuse diabetic macular oedema, persistent pseudophakic cystoid macular oedema, british journal of ophthalmology cover letter, central retinal vein occlusion, and exudative age related macular degeneration.
Fluorescein angiograms showed a mottled appearance of the retinal pigment epithelium close to the foveola, and a leakage of dye in the late phase of the angiogram.
com PostScript partial resorption of the subfoveal fluid 13 british journal of ophthalmology cover letter after the injection may not have necessarily been caused by intravitreal triamcinolone but may be explained by the natural course of the disease.
The report agrees with other british journal of ophthalmology cover letter in which patients with central serous chorioretinopathy did not markedly benefit from systemic steroid treatment. J B Jonas, B A Kamppeter Department of Ophthalmology, Faculty of Clinical Medicine Mannheim, Ruprecht-Karls-University of Heidelberg, Germany Figure 1 Fluorescein angiogram taken before the intravitreal injection of triamcinolone acetonide.
Mottled appearance of the retinal pigment epithelium, and shallow detachment of the fovea. no clear smoke stalk phenomenon fig 1. In optical coherence tomography, the central retina was detached.
Despite intensive topical treatment with prednisolone acetate eye drops and oral intake of carboanhydrase inhibitors, the morphological appearance of the fovea and visual acuity remained unchanged. Under topical anaesthesia, the patient received an intravitreal application of 20—25 mg of triamcinolone acetonide, which was transconjunctivally injected through the pars plana into the centre of the vitreous cavity.
The technique has already been described in detail. After the injection, all topical and systemic medication for his macular disorder was stopped. Within the first british journal of ophthalmology cover letter months after the injection, fluorescein angiograms and optical coherent tomograms did not show any marked changes in the macula fig 2. Intraocular pressure increased up to levels of 30 mm Hg and was reduced to the normal values by topical application of a carbonic anhydrase inhibitor.
Thirteen months after the injection, the fovea was still slightly detached. The clinical course suggests that in this eye with longstanding central serous chorioretinopathy an intravitreal injection of a high dosage of triamcinolone acetonide was not accompanied by a fast resolution of the subfoveal fluid and an increase in visual acuity.
For more than 5 months after the injection, the fovea remained clearly detached.
