Malignant melanoma of the lacrimal sac is very rare and primary malignant melanoma is extremely rare. It is usually diagnosed at an advanced stage after excision or biopsy of a tumor. We treated a patient with tearing and bloody discharge from the left eye. We performed a dacryocystectomy with the suspicion of a chronic dacryocystitis. However, the pathological findings and the immunohistochemi...

Chronic dacryocystitis results very often from obstruction to the nasolacrimal duct. It manifests as epiphora or watering of the eyes. The lacrimal sac gets expanded and also the wall of the sac gets thickened as a result of collection of mucopus due to obstruction of the nasolacrimal duct. Treatment of chronic dacryocystitis is by a surgical approach which consists of making an opening between...

BACKGROUND Granulicatella adiacens, a recent taxonomic addition, is a commensal organism of the oral, gastrointestinal, and urogenital tracts and is rarely encountered in the orbit and eye. FINDINGS We present a 46-year-old Caucasian woman with chronic dacryocystitis who underwent an external dacryocystorhinostomy and was found to have G. adiacens. CONCLUSIONS This is an unusual causative o...

Background/objectives: Acute dacryocystitis, or inflammation of the lacrimal sac with abscess, is almost always secondary to nasolacrimal duct obstruction. The standard practice for treatment is incision and drainage because of concerns about the risks of exacerbation and spread of infection. Here, we tried to evaluate primary endoscopic dacryocystorhinostomy (EnDCR) as a treatment for acute da...

PURPOSE The aim of this study was to determine the microbiology of primary acquired nasolacrimal duct obstruction (PANDO) and its antimicrobial susceptibilities. METHODS Ninety-three patients (100 eyes) diagnosed with PANDO, categorized as acute, chronic dacryocystitis, or simple epiphora, were prospectively enrolled. Lacrimal sac contents were cultured for aerobic and anaerobic bacteria and ...

INTRODUCTION Chronic dacryocystitis results in chronic infection and inflammation of the lacrimal sac. OBJECTIVE To identify the aetiology of chronic dacryocystitis and to determine their antimicrobial susceptibility pattern. MATERIALS AND METHODS A cross - sectional study was undertaken including 120 lacrimal swab materials collected from patients aged above 15 years suffering from chronic...

UNLABELLED The lacrimal sac is the structure most vulnerable to injury when performing rhinoplastic osteotomies. When performed in a low lateral position or along the frontal process of the frontal-maxillary suture, osteotomies can potentially tear the medial canthal tendon and injure the underlying lacrimal sac, possibly resulting in dacryocystitis. In this case report, the authors discuss a c...

PURPOSE To determine the success rate of conventional dacryocystorhinostomy (DCR) and endoscopic DCR performed in patients with acute dacryocystitis. METHODS Records of patients with acute dacryocystitis and operated during 2007-2008 were reviewed. Patients who completed a follow-up of 60 months were included in our study. Demographic characteristics, surgery types, success rate, and follow-u...

online | memorias.ioc.fiocruz.br Sporothrix schenckii is a dimorphic fungus that is responsible for cutaneous disease in endemic areas worldwide. Classically, infection is associated with a traumatic subcutaneous inoculation of contaminated soil, plants or organic matter. The most common clinical form of sporotrichosis is cutaneous, lymphatic disease, which accounts for 75% of cases, followed b...
