ABSTRACT
Chromomycosis is a chronic cutaneous fungal infection characterized by the presence of dark brown parasitic forms of fungi in biopsied tissues. It is usually resulted from the entry of the causative organism through a minor trauma, and therefore, most lesions are found on the exposed part of the body, such as limbs or face, and occurrence on the nasolacrimal duct is extremely rare. We report a case of chromomycosis of the right nasolacrimal duct, which was presented with clinical symptoms of nasolacrimal duct obstruction. The patient was a 40 year-old male who had had minor injuries on his left eye twice by paper and branches of the tree two months prior to epiphora in right eye. On dacryocystorhinostomy, right nasolacrimal duct was obstructed by pinkish brown mucoid ball. Microscopically, the mucoid ball revealed eosinophilic, amorphous, necrotic materials admixed with brown pigmented fungi. The organism showed characteristic dark brown, round, thick-walled, often septated, sclerotic bodies and brown pigmented long bead-like hyphae. The adjacent mucosa shows marked chronic nonspecific inflammation with fibrosis.
