Nasopharyngeal carcinoma is a unique head and neck malignant tumor in terms of epidemiology, pathology, and prognosis. It has been demonstrated that the pathogenesis of nasopharyngeal carcinoma is associated with Epstein-Barr virus (EBV). A 52-year-old man was referred for a solitary erythematous patch on the left cheek. The biopsy specimen showed nasopharyngeal carcinoma with positive EBV RNA stain. The incidence of cutaneous metastasis is rare. When skin metastasis develops, it suggests a progressive state of the disease, although it is common for distant metastasis to occur at other sites. Herein, we describe our experience with an uncommon case of nasopharyngeal carcinoma presenting cutaneous metastasis. (Korean J Dermatol 2019;57(2):80∼83)

목적: 인공수정체 혼탁으로 오인된 지연 낭폐쇄증후군 1예에 대한 진단 및 치료경험을 보고하고자 한다. 증례요약: 59세 남자가 1년 전부터 진행된 우안 시력저하를 주소로 내원하였다. 고혈압 외에는 특이병력이 없었으며, 10년 전 타 병원에서 양안 백내장수술을 받았다. 안과 개인의원에서 우안 인공수정체 변성으로 인한 혼탁으로 진단받고 인공수정체 교체를 위해 본원으로 전원되었다. 내원 당시 나안시력은 0.06이며, 안압은 22 mmHg, 굴절력은 인공수정체 부위의 혼탁 때문에 측정되지 않았다. 세극등현미경검사에서는 인공수정체의 부위가 우유빛 변성으로 관찰되었다. 전안부 빛간섭광학단층촬영에서 인공수정체 뒤쪽 고반사 물질의 저류가 관찰되었고, 초음파생체현미경검사에서는 수정체 후낭의 팽창이 확인되었다. Neodymium-doped yttrium aluminium garnet (Nd:YAG) 레이저 후낭절개술을 시행한 후 합병증 발생 없이 나안시력이 1.0으로 호전되었다. 결론: 낭폐쇄증후군은 백내장수술 후 1일에서 2주 사이에 드물게 발생하는 합병증인데, 술 후 10년이 지나서도 발생하는 지연 낭폐쇄증후군은 전형적인 임상양상과 달리 나타나기에 인공수정체의 변성으로 인한 혼탁과 감별이 매우 중요하다. Purpose: We report a case of late-onset capsular block syndrome, which resulted in a misdiagnosis of intraocular lens (IOL)opacity. Case summary: A 59-year-old man visited our clinic with reduced visual acuity in the right eye from 1 year prior. He had undergone uncomplicated bilateral cataract surgery by phacoemulsification with IOL implants at another hospital 10 years before. There was no specific history with the exception of hypertension. After being diagnosed in the ophthalmology clinic with IOL degeneration and opacity in the right eye, he was referred to our hospital for IOL replacement. Upon examination, his right uncorrected visual acuity was 0.06 and intraocular pressure was 22 mmHg. The refractive error could not be checked due to IOL opacity. Slit-lamp microscopy revealed a cloudy, milky IOL. Anterior-segment optical coherence tomography of the right eye showed retention of a highly reflective material in the lens capsule behind the IOL. Posterior capsule enlargement of the right eye was confirmed on ultrasound biomicroscopy. After neodymium-doped yttrium aluminium garnet (Nd:YAG) laser capsulotomy was performed, the homogeneous space disappeared and the eye recovered normal visual acuity. Conclusions: Capsular block syndrome is a rare complication that can occur shortly (1 day to 2 days) after cataract surgery. Late-onset capsular block syndrome, which occurs 10 years after surgery differs from typical clinical manifestations. Thus, capsular block syndrome is an important consideration upon the presentation of opacification due to IOL degeneration.

Purpose: To report Two cases of Thelazia callipaeda from the canaliculus after irrigation of lacrimal duct Case Summary : A 82-year-old male patient and a 64-year-old male patient presented with symptoms of epiphora, itching, and a sense of foreign body. Patients did not report having had flies in their eyes, and keep animals such as dogs, cats, and cows. After the irrigation of lacrimal duct, actively moving worms were identified in conjunctiva and were extracted with forceps. Extracted worms were a white thread-like round worm, 10-15 mm in size. The presence of the Thelazia callipaeda worms was confirmed by light microscopic findings. The patients’ symptoms resolved and there were no recurrences. Conclusions : Thelazia callipaeda usually lie in the ocular surface, causing ocular surface disease. After removal the worms, symptoms are resolved. For treat and prevention of the thelaziasis, the continious study about life cycles and routes of infection of Thelazia callipaeda is necessary.
