Abstract

Neurofibroma, a benign peripheral nerve sheath tumor, usually appears together with café-au-lait spots, iris nodules, and other tumors within the scope of neurofibromatosis von Recklinghausen type 1 tumors. A solitary neurofibroma of the eyelid is relatively rare. In this case report, we present a 39-year-old woman who had a lesion on the eyelid crease, previously treated as a chalazion. Due to persistent wound crusting, the lesion was excised above the tarsus. Pathological examination revealed a solitary neurofibroma. The patient did not have other clinical symptoms of neurofibromatosis, and there was no recurrence of the nodule during the 1-year follow-up.

Introduction

Although eyelid lesions are mostly benign,Citation1 obtaining an accurate clinical diagnosis remains challenging for primary physicians, dermatologists, and ophthalmologists in many circumstances. Various eyelid tumors of different origins can be masqueraded as chalazions, including sebaceous gland carcinomas,Citation2 neurilemomas,Citation3 and Merkel cell tumors,Citation4 but seldom neurofibromas.Citation5 Here, we report a neurofibroma of the eyelid simulating a persistent chalazion without a concurrent pathology of neurofibromatosis. This is a case report collected by clinical observation, surgical intervention, and pathological studies. Consent for publication was obtained from the patient.

Case report

A 39-year-old Taiwanese female had a painless eyelid mass on her right eye for 5 years. She had undergone blepharoplasty for trichiasis in her early 20s, and there was no other remarkable past medical history such as trauma or systemic disease. She was treated by an incision and curettage for the eyelid mass 2 years prior at a local clinic after a tentative diagnosis of chalazion. No pathological examination of the curetted specimen was done at that time. However, the lesion did not subside after the procedure. Upon ophthalmic examination, a nodule with a crusted wound was found at the margin of the right upper eyelid (). There were no other anomalies found in the fornix, anterior chamber or fundus. There was no palpable mass at the orbit and no restriction of eye movement.

The skin was incised horizontally at the wound, where necrotic tissue and soft tissue above the tarsus was excised for clinical pathology. The wound healed with no complications.

The histopathology results () showed a well-circumscribed but unencapsulated collection of wavy-like spindle cells within a myxoid background. Immunohistochemistry stain showed a diffuse and strong S100 positive, indicating the presence of neural cells. These findings are diagnostic for neurofibroma.

Biomicroscopic examination did not reveal any Lisch nodules on the iris; meanwhile, neither light brown spots on the skin nor subcutaneous neurofibroma lesions were found elsewhere on the body. Therefore, her eyelid lesion was characterized as a localized neurofibroma. During the 1-year follow-up period, no recurrence of the tumor was noted on the eyelid.

Discussion

Neurofibromatosis Type 1 (NF1) is an autosomal dominant inherited disease with high penetrance. The NF1 gene is cloned on chromosome 17q11.2.Citation6 The gene product, neurofibromin, is highly expressed in the nervous system and is regarded as a tumor suppressor.Citation7 Commonly derived from neural crest mesenchyme, pathogenesis includes melanocytic lesions involving the skin and the eye, and neurogenic lesions (mostly glial cell lesions) such as nodular neurofibroma, plexiform neurofibroma, and optic glioma. According to the National Institutes of Health Consensus Development Conference, the criteria for the diagnosis of NF1 include cafe-au-lait spots on the skin, neurofibroma, plexiform neurofibroma, freckles in the axilla or groin area, iris Lisch nodules, optic pathway glioma, bony dysplasia, and a first-degree relative with NF1. However, the presentations are variable and even the individual carrying the gene has an unpredictable expression.Citation8

Among the peripheral nerve sheath tumors involving the eye and adnexa, neurofibroma is the most common, followed by schwannoma tumors and neuromas.Citation9 Whereas plexiform neurofibromaCitation10 and multifocal neurofibroma are mostly associated with NF1,Citation11 solitary neurofibroma of the eyelid can also present without other systemic involvement.Citation12,Citation13 Other locations for solitary neurofibroma include the tongue,Citation14 palatine tonsil,Citation15 mandible,Citation16 and peritoneum.Citation17

The eyelid skin, despite being thin, is composed of multiple histological elements and hence capable of harboring tumors of different origins.Citation18 Huang et alCitation1 reviewed 4,521 pathological specimens of eyelid tumors in a tertiary medical center and found 5% of them were malignant. Among those malignant tumors, basal cell carcinoma was most common (21.1%), with squamous cell carcinomas coming in second (10.1%).

Chalazion, the chronic lipogranulomatous inflammation of the sebaceous gland, is a relatively benign entity which is commonly encountered. However, a persistent lesion with a poorly healed wound should raise the suspicion of other etiologies. Several types of tumors, both benign and malignant, have been tentatively diagnosed as a chalazion and later proven otherwise. Ozdal et alCitation19 retrospectively evaluated 1,060 cases with a clinical diagnosis of chalazion and found that, although mostly accurate, 6.4% cases were misdiagnosed. Among those, 15 cases (1.5%) were malignant tumors. The most common malignant eyelid tumors on the misdiagnosed list were basal cell carcinomas, followed by sebaceous gland carcinomas.

Conclusion

Herein, we reported a case of a solitary eyelid neurofibroma without neurofibromatosis. The lesion on the eyelid margin appeared in the 4th decade of the patient’s life, previously masquerading as a chalazion. After the en bloc excision, our patient had no clinical evidence of nodule recurrence during the 1-year follow-up. In the current report, the solitary neurofibroma was on the eyelid margin and resembled granulation tissue of chronic inflammation, differing from one beneath the tarsal plate in the previous article by Shibata et al.Citation5 Although the presentation of this benign entity varied from that of a traditional neurofibroma, it should be included as a differential diagnosis with eyelid lesions. We would also like to emphasize that a histopathological evaluation is recommended for persistent or atypical chalazions of the eyelid.
