Xanthogranuloma of the corneoscleral limbus in an adult

Clinicopathological study of ophthalmic cutaneous and mucocutaneous non-langerhans cell histiocytic lesions

BACKGROUND

The "C group" of the histiocytic disorders is characterized by non-Langerhans-cell histiocytic lesions in the skin, mucosal surfaces, or both, out of which Juvenile xanthogranuloma (JXG) is the most common typically affecting the skin. The eye is the most common extra-cutaneous site of JXG., we aim at providing our clinical and histopathological experience with this group of diseases including the adult-onset xanthogranuloma (AXG).

METHODS

This is a retrospective cohort study of all patients with the tissue diagnosis of ocular and periocular cutaneous and mucocutaneous non-LCH disorders who presented to us over a period of 25 years (January 1993 to December 2018).

RESULTS

Twenty patients were diagnosed as "Group C" disease with an age range of 2 months-60.9 years. Eleven patients were females (55%) and nine were males (45%). The involvement was mostly unilateral in 80.9%. All cases fell into the xanthogranuloma family with 11 JXG patients, 8 AXG patients of skin and ocular surface, and one patient with solitary reticulohistiocytoma (SRH). The clinical site of involvement in JXG was primarily in the eyelid in 5 patients (45%), ocular surface lesions in 2 (18%), iris in 2 (18%), choroidal and bilateral orbital lesions in 1 patient each (9%). The group of AXG, presented equally with eyelid lesions in 4/8 and ocular surface lesions in 4/8. The non-Langerhans' histiocytic infiltrate showed supportive immunohistochemical staining properties (reactive to CD68 marker and negative to S-100 and langerin markers).

CONCLUSION

Among the rare histiocytic disorders, xanthogranulomatosis is the commonest and has wide clinical manifestations. Accurate diagnosis needs to be supported by typical histopathological findings. JXG was the commonest in our study with relatively older mean age at presentation and frequent eyelid rather than iris involvement. AXG is often confused with xanthelasma when involving the eyelids with corneal limbal involvement is relatively frequent.

Adult onset xanthogranuloma of the eyelid

Purpose

To report a rare case of an eyelid lesion in an adult, with histological features of juvenile xanthogranuloma (JXG).

Observations

Juvenile xanthogranuloma primarily affects the skin of infants and young children. It infrequently can involve the structures of the eye and orbit and rarely occurs in individuals beyond the second decade of life. We present a case of adult onset xanthogranuloma (AXG) involving the eyelid of a 29-year-old female. This lesion required management with multiple treatment modalities.

Conclusions

This is a rare example of an eyelid xanthogranuloma in an adult. As such, JXG-like lesions should be included as a differential diagnosis for lesions of the eye and orbit in adults. Surgical management may be required if there is no response to intralesional steroids.

Corneal xanthogranuloma in association with multiple endocrine neoplasia 1: A clinicopathologic case report and review of the literature

Juvenile xanthogranuloma (JXG) is a benign inflammatory condition of uncertain pathogenesis. It is characterized by skin and ocular involvement – typically in the iris – in children. It has been reported in older age groups and has been also observed to involve other ocular structures such as the cornea and conjunctiva.

In this case report, we are presenting an extensive right eye corneal lesion in a 43-year old male which showed the typical histopathological feature of JXG and in association with multiple endocrine neoplasia (type 1). Similar cases in the English-language literature have been also reviewed.

The epidemiology, clinical characteristics, histopathology and management of juvenile- and adult-onset corneoscleral limbus xanthogranuloma

PURPOSE

Adult-onset xanthogranuloma (AOX) of the corneoscleral limbus is a rare inflammatory condition of unknown aetiology. Similar to limbal juvenile xanthogranuloma (JXG), it presents as a growing mass at the corneoscleral junction. Limbal AOX and JXG can lead to sight-threatening complications if not managed in a timely manner. This systematic review summarises the main clinical and histopathological features of limbal AOX/JXG and discusses the management of this uncommon disease.

METHODS

We performed a literature search in the MEDLINE database for all historical entries, using the search terms "limbus", "limbal" and "xanthogranuloma", and retrieved all articles reporting on limbal xanthogranuloma. After refining the search to articles relevant to limbal AOX, we were able to identify ten adult cases of limbal AOX and compare those with all reported cases of limbal JXG.

RESULTS

Clinically, AOX usually presents as an isolated smooth, yellowish, dome-shaped nodule at the corneoscleral junction, similar to an ocular presentation of JXG, with which it also shares similar histopathological features.

CONCLUSION

Limbal JXG and AOX may represent the same disease entity. Diagnosis relies on the clinical presentation, pathology and immunohistochemical profile. Spontaneous regression is unlikely, and thus prompt surgical intervention should be considered to prevent sight-threatening complications. Xanthogranuloma should be included in the differential diagnosis of corneoscleral limbal masses in patients of all age groups.

[Juvenile xanthogranuloma of the corneoscleral limbus]

An 18-year-old patient presented with a solitary limbal tumor on his left eye that had appeared and increased in size for 3 weeks. This mass did not display any extension into the anterior chamber on gonioscopy. Excisional biopsy by lamellar sclerokeratectomy was carried out and the lesion was sent for histologic examination. The pathologic diagnosis showed the characteristic picture of juvenile xanthogranuloma with numerous Touton giant cells. There was no recurrence after a 9-month follow-up. The diagnosis of isolated ocular juvenile xanthogranuloma may be difficult and histologic examination of ocular lesions is often necessary. When juvenile xanthogranuloma affects the uvea, treatment is medical. When it appears as a limbal mass, treatment is surgical. Juvenile xanthogranuloma should always be considered a differential diagnosis of a limbal mass, especially in children.

Juvenile xanthogranuloma of the corneoscleral limbus

PURPOSE

To report an 11-year-old Chinese girl with juvenile xanthogranuloma of the limbus, occurring in isolation without dermatologic involvement, and to discuss the clinical and histologic features, pathogenesis, and treatment of juvenile xanthogranuloma.

METHODS

Case report and review of medical literature.

RESULTS

A total excision and biopsy of the limbal lesion with lamellar graft was performed. Histologic examination showed a xanthogranuloma. At 12-month follow-up, there was no recurrence of tumor.

CONCLUSION

The diagnosis of juvenile xanthogranuloma may be straightforward in cases that have concomitant cutaneous manifestations. However, in isolated ocular forms, histopathological examination is necessary. Unlike the more common iris lesions that are preferably treated nonsurgically, limbal lesions require surgical excision.
