A molluscum contagiosum nodule, situated at the palpebral conjunctiva of the left lower eyelid at the level of the marginal and tarsal conjunctiva, was observed in a 53-year-old male. A mild follicular conjunctivitis was present, except in a zone immediately below the molluscum. On the corresponding site of this molluscum at the bulbar conjunctiva, the limbus and the cornea, no follicles, epithelial keratitis nor erosions were seen. Clinical diagnosis in atypically situated mollusca can be difficult. Cytological studies in these cases are very helpful. Alcohol-carbowax fixated and Papanicolau stained preparations proved to be very satisfactory for cytological examination. It has never been reported that a molluscum, situated in the palpebral conjunctiva, disappeared spontaneously.

This is the case of a female child with molluscum contagiosum widely disseminated around the mouth and the eye-lids. Antibiotics were used to stop local staphylococcal superinfection. Follicular conjunctivitis and keratitis punctata disappeared only after complete removal of all cutaneous lesions. Biological diagnosis was done by direct observation of the Poxvirus with the electron microscope, since isolation of the virus itself is impossible. Ultrastructural study of the excised tumor has shown the different stages of the growth of the virus, and the associated cellular lesions.

One case of molluscum contagiosum of the lid, which has been followed by follicular conjunctivitis and superficial punctate keratitis, has enabled us to compare the ultrastructure of the skin tumor and of the conjunctival lesion. Electron microscopic observation is the only way for discovering the causal Poxvirus. Up to now isolation of the viral strain has not been possible. Examination of the skin tumor showed different maturation forms of the virus and associated cell alterations. In the conjunctiva there was an inflammatory reaction, with exocytosis and infiltration of the chorion by lymphocytes and plasma cells. Intracytoplasmic organelles were formed in the superficial epithelial cells. Their size and structure resembled that of the immature virions found in the epidermic cells. The comparison between skin and conjunctival lesions suggests the following sequence of events in the pathogenesis: the virus, leaving the lid tumor, probably penetrates the conjunctival cells and, without finding the conditions necessary for its full development, produces abnormal viral inclusions unable to become a mature virus. The excision of skin nodules thus cures the infection, since it prevents further reinfection by the skin virus. The morphological criteria on which this hypothesis is based must be confirmed by chemical and morphometrical studies.

External ocular disease associated with human immunodeficiency virus (HIV) infection can often be overlooked by the eye care practitioner. Different types of external ocular disease can be an indication of the patient's overall immune status as well as the stage of HIV infection. The external ocular sequelae of HIV infection can be of visual consequence for the patient. Eye care practitioners need to become familiar with these conditions. The diagnosis and management of the following ocular conditions associated with HIV infection are reviewed: conjunctival microvascular disease, dry eye, allergic conjunctivitis, microsporidial keratoconjunctivitis, herpes zoster ophthalmicus, herpes simplex keratitis, molluscum contagiosum, fungal keratitis, bacterial keratoconjunctivitis, and Kaposi's sarcoma (KS).

Inflammatory eye diseases in Aids patients are common. For CMV-retinitis an incidence of up to 45% is reported in the literature. Other retinal diseases such as acute retinal necrosis are less common but are difficult to treat and often follow a disastrous course. Ocular lues may present very different clinical pictures and is the great "imitator" in AIDS patients as well. In toxoplasmosis the typical chorioretinal scars next to the acute inflammatory infiltrates are commonly absent. Infections with candida occur in i.v. drug-addicts in particular. Bacterial corneal ulcers and herpetic keratitis are not more common in HIV-positive patients than in immunocompetent individuals, but the course of the disease is often more severe and prolonged. In patients with low CD4 counts Microsporus can cause painfull keratitis. Mollusca contagiosa are more common in AIDS patients and show the typical lesions, though these are greater in number (commonly more than 20) or in unusual localizations (mucous membrane).

In reviewing the clinical features, diagnostic evaluations and therapies of the most common ocular viral infections we attempt to whet your appetite for attacking the numerous challenges in diagnosis and treatment of viral eye disease. The herpes viruses, HSV, VZV and CMV are the cause of significant ocular morbidity. HSV most commonly affects the cornea producing keratitis that can be recurrent and may lead to corneal clouding and neovascularisation. Manifestations can be purely infectious or immunological and treatment options must be tailored to the underlying pathophysiology. Herpes zoster ophthalmicus, caused by VZV infection of the first branch of the trigeminal nerve, produces a characteristic rash and can progress to keratitis and uveitis. HSV and VZV can cause retinitis in both immunocompetent and immunocompromised individuals. There has been a significant increase in the incidence of CMV retinitis since the beginning of the AIDS epidemic. We review the numerous new treatments, diagnostic tests and treatment strategies which have been developed in response to this potentially blinding retinal infection. Adenovirus produces an epidemic conjunctivitis and epidemic keratoconjunctivitis which are severe and extremely contagious conjunctival infections. HIV, molluscum contagiosum, EBV and rubeola also cause ocular diseases which are described.Copyright 1998 John Wiley & Sons, Ltd.

In order to determine the clinical and laboratory findings of Iranian patients with presumed hyper-immunoglobulin E syndrome (HIES), the medical records of 22 patients from 21 unrelated families, who had been registered in the Iranian Primary Immunodeficiency Registry, were observed. The median age of patients at the time of first symptom and at the time of diagnosis was 1 month and 52.5 months, respectively, with a median diagnosis delay of 70 months. 13 families had consanguineous marriages. IgE level was higher than 2000 IU/ml in all patients, ranging from >2000 to 80,000 IU/ml. The most commonly occurring manifestations were: eczema and dermatitis, pneumonia, upper respiratory tract infections, cutaneous abscesses, diarrhoea, deep abscesses, and otitis media. Other less frequent manifestations were: mucocutaneous candidiasis, sinusitis, cutaneous ulcers, Molluscum contagiosum, herpetic keratitis, onychomycosis, conjunctivitis, septic arthritis, and meningitis. Five patients were complicated by bronchiectasis due to recurrent pneumonia and 5 patients died because of severe infections and malignancy. The HIES is a multisystem disorder that affects especially cutaneous, respiratory, skeletal and the immune system. Although HIES is a rare condition, the recurrent infections should always raise a suspicion, which deserves further evaluation for detecting the syndrome.
