Patients often have poor visual acuity, photophobia, nystagmus, and absent color vision. Since the first case report in 1988, the metal cation transport mediator 4 (CNNM4) gene residing at chromosome locus 2q11.2 is discovered to be a causative gene of Jalili syndrome in 2009 [2,3]. We report the first Korean case of Jalili syndrome carrying compound heterozygous causative variants with a novel missense variant in CNNM4. A 7-year-old boy visited Seoul St. Mary’s Hospital with uncorrected vision. He was the first baby of nonconsanguineous parents and was born at 38 weeks gestation with a birth weight of 3.35 kg. There was no previous family history of ocular, systemic, or chromosomal disorders. He had a mild hyperopic refractive error of +1.5 diopters. He had been wearing glasses for several years, but his best-corrected visual acuity was 20 / 200 in both eyes. Photophobia and slow pendular nystagmus were also observed. Fundus examination revealed a normal-looking optic disc and macula (Fig. 1A, 1B). Whereas widefield fundus photography and fundus autofluorescence did not reveal any definite abnormalities, the blurring of ellipsoid zone was noted on optical coherence tomography (Fig. 1C–1F). A full-field electroretinogram (RETI-scan, Roland Consult) showed severely reduced responses in the cone and rod systems in both eyes (Fig. 1G). After obtaining written informed consent from his parents, next-generation sequencing (NGS) was performed for the genetic analysis. Targeted panel sequencing was done with 439 genes, which were reported as being related to inherited retinal dystrophy. Subsequently, compound heterozygous missense variants of c.1511T>G, p.(Ile504Ser), and c.344T>C, p.(Leu115Pro) in the CNNM4 (reference sequence, NM_020184.4) were identified. The c.1511T>G, p.(Ile504Ser), is in the cystathionine-β-synthase domain which is evolutionarily conserved and known to play essential roles in the regulation of the activities of numerous proteins (PMID: 31347285, 16275737, 14722619). Population frequencies were extremely low (0.0000544 in East Asian populations and 0.00000398 in all ethnicities, according to gnomAD exome), and the variant was predicted to have a deleterious effect by multiple line in silico tools, including MutationTaster [4], PolyPhen-2 [5], and SIFT [6]. Based on these facts, we classified the mutation as likely pathogenic according to the American College of Medical Genetics and Genomics guidelines. A c.344T>C variant has never been reported in a population database. It causes a p.(Leu115Pro) amino acid change, and this position is conserved (phyloP100way, 6.03); multiple in silico tools such as FATHMM-MKL [7], MutationTaster [4], and PolyPhen-2 [5] predicted a deleterious effect by affecting the protein synthetic process.

There have been six cases reported worldwide and here, we would like to introduce the first case of the inverted mucoepidermoid papilloma of conjunctiva in Korea. Written informed consent for publication of the clinical images was obtained from the patient. A 56-year-old man presented with right conjunctival mass found 2 months ago. He had no other underlying diseases except hypertension. His corrected visual acuity was 20 / 16 in both eyes. About 0.5 × 0.3-cm-sized pigmented and vascularized pedunculated mass was seen over the right inferior palpebral conjunctiva (Fig. 1A). The mass was soft and painless in nature. An excisional biopsy was performed, and the brownish sample was measured 0.5 × 0.3 × 0.2 cm. Histopathologic examination showed a single fragment lined by stratified squamous cells, with downward extension of conjunctival epithelium (Fig. 1B, 1C). Cystic components were visible in the lobules of nonkeratinizing squamous epithelium. Many goblet cells were found. No definite evidence of inflammation, dysplasia, and necrosis was found. Heuring et al. [1] reported peripheral carcinomatous foci within the lesion in their case of inverted transitional cell papilloma, whereas there was no evidence of malignancy in this case. On follow-up examination, his tarsal conjunctiva of the right lower lid was clear without remaining pigmented lesion (Fig. 1D). No recurrence was reported in up to 6 months of follow-up. Inverted papilloma is less common compared to exophytic papilloma in conjunctiva, with epithelium invaginating into the substantia propria endophytically. It is usually found in nasal cavity or paranasal sinuses, and there have been some case reports regarding local recurrence and malignant transformation of the tumor [2]. On histopathologic examination, inverted papilloma involving conjunctiva quite differ from inverted papilloma of other sites, featuring distinct cystic components within acanthotic lobules. Based on this finding, Jakobiec et al. [3] recommended the term inverted mucoepidermoid papilloma. Since inverted mucoepidermoid papilloma can be misdiagnosed as conjunctival nevus or malignant melanoma, definitive diagnosis should be made by histopathologic examination. There is no report on local recurrence or malignant transformation of inverted mucoepidermoid papilloma in conjunctiva, though there is no data on long-term follow-up of inverted mucoepidermoid papilloma over 5 years due to the rarity of the subtype [4]. In conclusion, we present a first case of inverted mucoepidermoid papilloma of conjunctiva in South Korea, which is an exceedingly rare neoplasm. Although inverted mucoepidermoid papilloma is extremely rare, it should be considered as a differential diagnosis of pigmented conjunctival mass.","PeriodicalId":17883,"journal":{"name":"Korean Journal of Ophthalmology : KJO","volume":"37 2","pages":"190-191"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/4a/02/kjo-2022-0121.PMC10151175.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9401655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are fewer complications related to postoperative discomfort and suture; only minor complications, such as subconjunctival hemorrhage and chemosis, have been reported [1,2]. To the best of our knowledge, this is the first report of an human papillomavirus (HPV)-positive conjunctival papilloma in a patient who underwent high-frequency radio wave electrosurgery. Written informed consent for publication of the research details and clinical images was obtained from the patient. A 78-year-old Asian woman visited the outpatient with not having shed tears for 3 years and had irritation in both eyes, was treatmented for dry eye at a private hospital, but did not improve, so she visited Hanyang University Guri Hospital. On examination, she exhibited bilateral CCH. Conjunctival hyperemia, conjunctiva and plica semilunaris thickening, papillomatous lesion, and abnormal blood vessels were not visible in the conjunctiva (Fig. 1A, 1B). Even with proper dry eye treatment, the symptoms did not improve even after a month. Therefore, high-frequency radio electric surgery for CCH was planned and performed. Postsurgery, artificial tears, 0.1% f luorometholone, and 0.5% levofloxacin were instilled in both eyes four times a day. Two months after electrosurgery, the patient presented with hyperemia of both eyes and a burning sensation. She had a grayish-red, fleshy, and irregular surfaces on the inferior bulbar conjunctiva in the right eye. The left eye showed several small pedunculated masses in the inferior bulbar conjunctiva (Fig. 1C, 1D). Excisional biopsy was performed, and histological examination showed atypical squamous proliferation, moderate dysplasia, with a positive polymerase chain reaction (PCR) for HPV (low-risk type 11). Immunohistochemistry revealed that the right eye was p16-positive, p53-positive (15%), and Ki-67–positive (20%); the left eye was p16-negative, p53-positive (2%), and Ki-67–positive (10%) (Fig. 1E–1H). Topical mitomycin C 0.02% drops (four times a day for a week) were prescribed for both eyes. The drops were administered for a week, followed by a week of rest. Existing small recurrent lesions were resected during follow-up. As a result of observation after 5 months, no recurrence lesion was observed. Conjunctival papilloma is an acquired benign tumor that occurs in the stratified squamous epithelium of the conjunctiva. Exposure to solar ultraviolet radiation B is an important risk factor, and other risk factors include immunosuppression and the presence of HPV [3]. Patients with conjunctival intraepithelial neoplasia, conjunctival carcinoma in situ, or conjunctival squamous carcinoma showed HPV-positivity by PCR in 21% of primary tumors and 36% cases of recurrence [4].
