Juvenile xanthogranuloma (JXG) is a benign histiocytic disorder that belongs to the non-Langerhans cell group. Extracutaneous involvement in the eye usually involves the iris and presents as recurrent spontaneous episodes of hyphema or secondary glaucoma. A 3-year-old child presented with a subconjunctival mass in the left eye and concurrent scalp nodules. Ultrabiomicroscopic examination showed a moderately reflective episcleral mass with extension into cornea but no scleral involvement. Histopathology of the excised subconjunctival mass showed a dense infiltrate of polygonal/spindle mononuclear cells with moderate amounts of cytoplasm and scattered Touton giant cells, suggestive of JXG. Systemic evaluation did not reveal any other sites of involvement. Postoperatively, the patient was treated with topical steroids. At last follow-up 2.5 years, the patient is free on any recurrence.

Juvenile xanthogranuloma (JXG) is a cutaneous granulomatous disease that occurs primarily in infants but may occasionally affect older children and adults. It is characterized by orange red macules or papules that occur on face, neck, and upper trunk. These skin lesions generally resolve spontaneously between 1 and 5 years of age. Histopathologically, they are characterized by the presence of touton giant cells; absence of Langerhans cell histiocytes helps to differentiate the benign lesion from the more serious histopathological disorder known as Langerhans' cell histiocytosis., Herein, we report a case of JXG presenting in a 3-year-old child as a subconjunctival mass and also describe the imaging features of the same on ultrasound biomicroscopy (UBM).
| Case Report|| |
A 3-year-old male child presented with an ocular surface mass of 6 months duration. It was not associated with any ocular congestion or pain, and there were no other systemic complaints. On examination, it was 15 × 5.5 mm, smooth-surfaced, well-defined, pinkish mass located at superior limbus of the left eye with a 3 mm extension into the adjacent clear cornea [Figure 1]a and [Figure 1]b. Cardiff visual acuity was 6/9 in both the eyes. The anterior segment and fundus were normal on slit-lamp biomicroscopy and indirect ophthalmoscopy, respectively. Two yellowish red nodular lesions were also noted on the scalp [Figure 1]c. UBM of the ocular mass revealed a homogeneous mass with moderate echogenicity reaching a height of 5.5 mm and no scleral extension [Figure 1]d. Complete haemogram and peripheral blood smear were performed and found unremarkable. The subconjunctival nodule was excised after lifting and dissecting under the overlying conjunctiva and leaving the cornea untouched [Figure 1]e. On histopathological examination, the mass was composed of a dense infiltrate of polygonal or spindle mononuclear cells with moderate amounts of cytoplasm and scattered Touton giant cells suggestive of JXG [Figure 1]f. Systemic evaluation conducted by a pediatrician including computed tomographic scan head, ultrasound abdomen, and bone marrow aspirate was within normal limits. There was no associated central nervous system lesion. A diagnosis of JXG was made. Postoperatively, the child was treated with steroid eye drops and ointment. There was regression of residual corneal lesion with corneal opacification. At last follow-up of two-and-half years, the child was free of any ocular recurrence or systemic disease [Figure 1]g, [Figure 1]h.

| Discussion|| |
Mc Donaugh, a dermatologist, first reported the skin lesions of JXG as nevo xantho endothelioma in 1909. Subsequent studies found that nearly 10% of cases of JXG have associated ophthalmic presentation. In eye and adnexa, lesions of JXG may affect iris, ciliary body, optic nerve, eyelids, and sometimes orbit.,,,,,, Unlike dermal lesions that usually resolve spontaneously by the age of 5 years, ocular lesions can cause significant morbidity and typically need surgical intervention. Iris is the most common site reported to be affected and iris lesions tend to bleed spontaneously and recurrently causing uncontrolled secondary glaucoma and a painful blind eye that often requires enucleation. Eyelid and ocular surface lesions require surgical excision.
JXG affecting ocular surface is uncommon. On a review of literature, we found 20 cases of pediatric JXG reported to present with a subconjunctival mass. Of these, 15 (75%) cases occurred in children less than 5 years of age and 5 (25%) cases had associated skin lesions also [Table 1].,,,,,,,,,,,,,,, UBM features of ocular surface JXG lesion have been reported rarely. In previous reports by Lau et al. and Niu et al., authors described a moderately reflective mass with extension into sclera and corneal stroma. Surgical excision was done with lamellar sclerectomy and lamellar keratectomy, respectively, in these cases. In the current case, UBM showed a moderately reflective episcleral mass with no scleral extension. Intraoperatively, this finding was confirmed and the mass could be dissected of the sclera without need of lamellar scelerctomy. Thus, UBM can be useful for assessing the extent of JXG mass into the contiguous tissues. Ocular surface JXG can manifest as an episcleral mass with/without scleral invasion and a preoperative UBM can help in evaluating the need for lamellar scleralectomy.

The most common modality of treatment reported in a limbal JXG is surgical excision.,,,,,,,,, Although the exact pathology of JXG is unknown, the presence of histiocytes possibly shows a relationship with inflammation. Topical steroids are useful in treatment of iris lesions. However, steroids alone are insufficient in treatment of ocular surface lesions as reported by various studies and are mostly used as an adjunctive treatment. A complete excision is usually advocated as it prevents its extension to deep corneal stroma. Some authors prefer a lamellar corneal grafting to take care of corneal component.,,,
In the current case, we excised the subconjunctival mass leaving the corneal part untouched, which showed regression with topical steroids. However, it resulted in a residual corneal opacity. A lamellar corneal excision with corneal grafting may have avoided this.
| Conclusion|| |
To conclude, JXG may infrequently present as an ocular surface mass in children. JXG must be kept in the differential diagnosis especially if there are associated skin lesions or a history of the same is present. Complete surgical excision remains the treatment of choice. Preoperative UBM may be used to plan complete surgical resection.
