Ligneous conjunctivitis in a Dandy–Walker syndrome: A rare case report

Ligneous conjunctivitis (LC) is a rare form of pseudomembranous conjunctivitis seen in children, perhaps due to plasminogen deficiency, which manifest as a chronic refractory pseudomembranous conjunctivitis. LC cases are incapable in maintaining their fibrinolytic activity due to plasminogen deficiency; consequently, transudates of plasma assume as a thick, gelatinous, woody membranes over the mucosal surfaces. This is a short case report on a child with a LC, who presented with recurrent pseudomembranous conjunctivitis in conjunction with progressive congenital hydrocephalus due to aqueductal stenosis (Dandy–Walker syndrome). This rare association was clinically confirmed and prompt corrective surgical measures were instituted.

Plasminogenemia asociada a conjuntivitis leñosa / Plasminogen Deficiency and Ligneous Conjunctivitis

El artículo presenta el caso clínico de un joven de 18 años de edad sin antecedente familiares de enfermedad crónica o hereditaria, nacido a término, sin complicaciones, quien desde los dos días de vida presentó una lesión tipo masa en la conjuntiva tarsal. Inicialmente, recibió tratamiento farmacológico tópico y seguimiento por oftalmología, por conjuntivitis bilateral persistente, masas tarsales recidivantes y cataratas en ambos ojos, por lo que requirió siete intervenciones con pobre respuesta al manejo farmacológico y quirúrgico. A los seis meses de vida se le diagnosticó hidrocefalia, que requirió manejo con derivación del ventrículo peritoneal. Dada la persistencia de la sintomatología y la refractariedad al tratamiento, se ampliaron los estudios y en una junta médica se sugirió el diagnóstico de conjuntivitis leñosa asociada a alteración del plasminógeno. Este diagnóstico fue confirmado por laboratorio clínico, que mostró sus bajas concentraciones de plasminógeno en muestras tomadas con intervalos de dos meses en tres ocasiones: 16,9%, 11,1%, 18,6% (valores de referencia: 70-150%). Se le indicó heparina de bajo peso molecular antes de procedimientos quirúrgicos mayores y triamcinolona tópica según síntomas oculares.

We present a case of an 18-year-old patient without a family history of ocular disease, born full term without complications, within his first 2 days a mass in the tarsal conjunctiva appeared. Initially he received topical treatment and follow-up by the ophthalmology department with a diagnosis of persistent bilateral conjunctivitis, relapsing tarsal masses and cataracts in both eyes requiring a total of 7 surgical interventions with a poor response. At the age of 6 months he was diagnosed with hydrocephalus and required a ventricular-peritoneal shunt. Giren the persistence of the symptoms, further studies were made and a medical board made the diagnosis of ligneous conjunctivitis associated to low levels of plasminogen. The diagnosis was confirmed by decreased levels of plasminogen in serum measured three times with 2 months intervals: 16.9%, 11.1%, 18.6% (reference valúes 70'150%). Low molecular weight heparin was ordered before surgical procedures, and topical triamcinolone applied according to ocular symptoms.

Co‑existing ligneous conjunctivitis and IgG4‑related disease.

Herein, we elucidate that ligneous conjunctivitis (LC) was proved as an IgG4‑related disease (IgG4‑RD) by a series of pathologic studies from primary and recurrent episodes of an LC patient. LC was diagnosed based on clinical presentation and pathological appearance; furthermore, combined with serological examination and immunohistochemical study, the case also conformed to the diagnosis of IgG4‑RD. The IgG4‑RD, broadly discussed in recent times, is an idiopathic disease entity with tissue fibrosis possibly involving multiple organs. To the best of our knowledge, IgG4‑RD has never been reported with LC. By reporting the clinical course and literature review, we should pay attention to the association between these two diseases.

Successful treatment of ligneous conjunctivitis with topical fresh frozen plasma in an infant / Sucesso do tratamento da conjuntivite lenhosa com uso tópico de plasma fresco congelado em uma criança

ABSTRACTA 6-month-old female infant presented to our clinic with bilateral eyelid swelling, yellowish-white membranes under both lids, and mucoid ocular discharge. Her aunt had similar ocular problems that were undiagnosed. The conjunctival membranes were excised and histopathological investigation of these membranes showed ligneous conjunctivitis. Further, laboratory examination revealed plasminogen deficiency. A good response was observed to topical fresh frozen plasma (FFP) treatment without systemic therapy, and the membranes did not recur during the treatment. Topical FFP treatment may facilitate rapid rehabilitation and prevent recurrence in patients with ligneous conjunctivitis.

RESUMOUma criança feminina com seis meses de idade se apresentou à nossa clínica com edema palpebral bilateral, membranas brancas amareladas sob as pálpebras de ambos os olhos e descarga mucosa. Sua tia já havia apresentado problemas oculares semelhantes que não foram diagnosticados. As membranas conjuntivais foram excisadas e a investigação histopatológica das membranas demonstraram conjuntivite lenhosa. O diagnóstico de deficiência de plasminogênio foi obtido a partir de um exame laboratorial. Tratamento tópico com plasma fresco congelado (FFP) sem qualquer terapia sistêmica mostrou boa resposta. Não foram observadas recorrências das membranas. O tratamento tópico com FFP pode ajudar a reabilitação rápida e prevenir a recorrência em pacientes com conjuntivite lenhosa.

Ligneous conjunctivitis in a patient of juvenile colloid milia: A rare association.

We present to you, case of a 10-year-old female with h/o redness, watering since 8 months. Her vision was 20/30 in right eye and 20/70 in left eye. Conjunctiva had plenty of purulent discharge and palpebral conjunctiva was studded with membranous lesions. She was found to have multiple hyperpigmented papulopustular lesions over face, palms and legs. She was started with topical moxifloxacin and lubricating drops. Patient was followed-up after 15 days. At that time her conjunctiva had formation of a woody pseudomembrane. Excision of the lesions and skin biopsy was done and sent for hislopathological examination. Findings of histopathological examination were suggestive of ligneous conjunctivitis and juvenile colloid milia. We have started this patient with long-term cyclosporine drops and tear supplements. In next visit, the membrane was resolved. Hence, we continued with the same treatment, but again the woody membrane recurred.

Treatment of ligneous conjunctivitis with amniotic membrane transplantation and topical cyclosporine.

Ligneous conjunctivitis (LC) is a rare form of bilateral chronic recurrent disease in which thick membranes form on the palpebral conjunctiva and other mucosal sites. We report the clinical features and describe the management of two cases. Case 1 was an 8-month-old patient with bilateral membranous conjunctivitis. Case 2 was a 5-year-old patient with unilateral membranous conjunctivitis, esotropia, mechanical ptosis and complicated cataract, and had been treated with a number of medications. Histological investigation of the membrane in both cases showed LC. Treatments with amniotic membrane transplantation and institution of topical cyclosporine have shown good response. There has been complete resolution of the membranes with no recurrence at the end of 40- and 28-month follow-ups, respectively. No treatment related side effects were seen. Thus, it appears that amniotic membrane transplantation and topical cyclosporine are effective alternatives for the treatment of LC.
