  • Squamous cell carcinoma of the eyelid arising from palpebral conjunctiva
    European journal of dermatology : EJD, 2006
    Co-Authors: Sei-ichiro Motegi, Atsushi Tamura, Yoichiro Matsushima, Yayoi Nagai, Osamu Ishikawa
    Abstract:

    We reported a 58-year-old Japanese man with squamous cell carcinoma (SCC) of the left upper eyelid arising from the palpebral conjunctiva. The tumor had been incised by a former doctor under the diagnosis of chalazion. Histopathological examination of the relapsed tumor revealed atypical squamous cells invading towards the eyelid skin from the epithelium of palpebral conjunctiva. We performed a total resection of the tumor and reconstructed the upper eyelid by the technique of Mustarde's switch flap. During 10 months of follow-up, neither local recurrence nor metastasis has been detected and the reconstructed eyelids showed good course in function and in appearance. SCC of the palpebral conjunctiva is quite rare, however, it often resembles Chronic Conjunctivitis or chalazion. It is important to consider the possibility of SCC in addition to sebaceous carcinoma when we see a patient with an eyelid lesion, even one which looks like a benign condition such as Chronic Conjunctivitis or chalazion.

  • Chronic Conjunctivitis due to Mycobacterium tuberculosis.
    International ophthalmology, 2013
    Co-Authors: Sunita Chaurasia, Muralidhar Ramappa, Somasheila I Murthy, Geeta K. Vemuganti, Merle Fernandes, Savitri Sharma, Virender S Sangwan
    Abstract:

    To report the clinical characteristics and treatment outcome in six patients with Chronic Conjunctivitis due to Mycobacterium tuberculosis. In this retrospective observational case series, all patients with a diagnosis of conjunctival tuberculosis seen in our clinics between January 2000 and January 2010 were reviewed. The clinical presentation, diagnostic investigations and response to medical therapy and outcomes were analyzed. Six patients (age range 15–47 years) were diagnosed with conjunctival tuberculosis. The mean duration from onset of symptoms to diagnosis was 6.5 months (range 1–12 months). Of the six patients, two had ulceration, one had a nodulo-ulcerative lesion, one had bilateral nodular epibulbar masses, and one had a hypertrophied papillary lesion. Systemic signs of tuberculosis were noted in two patients—pleural effusion in one and preauricular and submandibular lymph node involvement in the other. All patients had resolution of symptoms after treatment with four-drug anti-tuberculosis therapy (ATT). None had ocular or systemic recurrences after completion of ATT. Tuberculosis of the conjunctiva can have varied clinical presentation. Although a rare entity, it should be suspected in non-responding Chronic Conjunctivitis. A high index of suspicion and clinical examination aided by appropriate microbiological and histopathological testing can help in early diagnosis and management.

  • Chronic Conjunctivitis From a Retained Contact Lens.

    Co-Authors: Jawad Arshad, Asma Saud, Darrell E White, Natalie A. Afshari, Rony R. Sayegh
    Abstract:

    Purpose To help clinicians diagnose and manage unilateral recalcitrant Chronic bacterial Conjunctivitis secondary to a retained soft contact lens and describe the first report of Gram-negative bacteria causing this condition. Methods Chart review of successive cases presenting with unilateral Chronic Conjunctivitis with positive cultures and a retained contact lens. Results Three cases were identified and described. Culturing of the retained contact lenses grew Pseudomonas aeruginosa in the first case, Achromobacter xylosoxidans in the second, and Staphylococcus epidermidis in the third. All three patients were successfully treated with removal of the retained lens and targeted antibiotic eyedrop therapy. Conclusions Unilateral Chronic recurrent or recalcitrant purulent papillary Conjunctivitis is rare, and a retained contact lens should be suspected in patients with a history of wearing contact lenses. Careful examination with double eversion of the upper eyelid and sweeping of the fornices can recover the offending lens. Although only Gram-positive organisms have been isolated in previous reports, two of our three cultures grew Gram-negative organisms, highlighting the importance of broad-spectrum antibiotic usage for these cases.
