Kimura's Disease of the Orbit Successfully Treated with Radiotherapy Alone: A Case Report

Kimura Disease of the Periorbita and Earlobe in a 15-Year-Old Male: A Case Report and Review of the Literature

PURPOSE

The authors describe a case of Kimura disease (KD) affecting the lacrimal gland, the ipsilateral periorbita, and the contralateral earlobe. The authors also review the literature for characteristics and outcomes of KD affecting the periorbita or earlobe.

METHODS

The authors review retrospectively a single chart and abstract data from the English language literature.

RESULTS

A 15-year-old Samoan male presented with a left upper eyelid mass and later the contralateral earlobe and ipsilateral periorbita. Surgical resection was partially effective and normal vision and eye motility were maintained. Histopathology was consistent with KD. Thirty-seven cases of periorbital KD were identified in the literature. The average age of patients with periorbital KD was 31.9 years (standard deviation: 17.8 years), with 81.1% (30/37) of patients being male and 69.4% (25/36) Asian. Over half of periorbital KD patients had lacrimal gland involvement (51.3%; 19/37). Fifteen patients were initially treated with surgery; 3 (20%) had recurrence of the disease. Another 15 patients were initially treated with corticosteroids; 12 (80%) had recurrence of the disease. Ophthalmologic data, when reported, demonstrated that, most patients had no visual (77.8%; 14/18 patients) or motility disturbances (82.4%; 14/17 patients) but most had proptosis 71.4% (10/14). Only 4 cases of earlobe involvement in KD were identified, all in women.

CONCLUSIONS

In the literature, orbital KD was rare but often affected the lacrimal gland and caused proptosis, commonly in young adult Asian males. Vision and extraocular motility were usually normal. Earlobe involvement was very rare. This unique case of KD that affected the orbit and contralateral earlobe corroborates the prior literature that KD is prone to recurrence but may not adversely affect vision or extraocular motility.

Optic neuropathy caused by orbital Kimura disease: A rare case report

RATIONALE

Kimura disease (KD) is a rare, chronic inflammatory disease characterized by painless subcutaneous nodules predominantly located in the head and neck regions. Orbital KD, which intrudes into the intraconal space and results in compressive optic neuropathy, is rare and has not been previously reported.

PATIENT CONCERNS

A 68-year-old man presented with blurred vision and progressive proptosis in the left eye that had been present for 2 years.

DIAGNOSIS

Magnetic resonance imaging of the brain revealed soft tissue lesions with contrast enhancement and restricted diffusion involving the bilateral eyelids, orbits, and intraconal region; those on the left side were more prominent than those on the right side. The lesion encased the left optic nerve. Laboratory test results revealed elevated serum immunoglobulin E level and peripheral eosinophilia. An orbital mass biopsy demonstrated hyperplastic lymphoid follicles with germinal centers in the subcutaneous area and abundant mononuclear and binuclear eosinophils infiltrating the interfollicular area. A pathological diagnosis of KD was made based on the blood test results.

INTERVENTIONS

Orbital decompression and debulking surgery of the orbital tumor in the left eye were performed to treat the compressive optic neuropathy.

OUTCOMES

After systemic oral steroid and immunosuppressive agent therapies, the patient's visual acuity in the left eye improved, and the KD activity was stable.

CONCLUSIONS

We present a rare case of orbital KD-associated optic neuropathy, wherein early diagnosis and treatment preserved the patient's vision. This complication should be considered in patients with a history of compressive optic neuropathy during the differential diagnosis.

Rare Diseases of the Orbit

This article provides an overview of rare orbital diseases. Congenital malformations, inflammatory diseases, benign and malignant neoplasias are described. Although it represents a relatively small area of the body the orbit contains multiple different tissues. Therefore, a great variety of diseases can be found within the orbital space. That is the reason, why both the completeness and the level of detail in the description of particular diseases must be somewhat limited. Nevertheless, clinical manifestations, important aspects of diagnosis, treatment strategies, and, when specific data are available, the prognosis are described. The authors tried to highlight the most characteristic aspects of the different diseases to describe their relevant aspects in spite of the brevity of the subsections.

Recurrent Kimura's disease of head and neck treated with intensity-modulated radiotherapy

Kimura's disease (KD) is a rare, chronic inflammatory disorder of unknown aetiology, which commonly affects men of the Asian race. Here, we present a case capsule of a 39- year-old man with KD of the left cheek, managed initially by surgery alone. He developed local recurrence after 6 months and was treated with steroids and isotretinoin. Eventually, steroids were discontinued due to toxicity and the lesion progressively increased in size. The patient was successfully treated using intensity-modulated radiotherapy with simultaneous integrated boost as a primary modality with minimal adverse effects. The patient has good local control and cosmetic outcome with no radiation-related toxicity at a follow-up period of 28 months.

Kimura's disease mimicking thoracic spine dumbbell neurogenic tumor: a case report and literature review

Background

Kimura’s disease is a rare, benign chronic inflammatory disease of unknown etiology that mostly affects Asians. The disease typically presents as subcutaneous masses in the head or neck region that are predominantly found in the preauricular and submandibular areas.

Case presentation

A 7-year-old boy presenting with paralysis of both lower extremities and a thoracic spine dumbbell mass was initially diagnosed with a neurogenic tumor, but the pathological and laboratory examinations confirmed the diagnosis of Kimura’s disease. The paralysis symptom disappeared rapidly, but the patient had developed a recurrent mass in the cervical vertebral canal at the 9-month follow-up.

Conclusion

To our knowledge, no prior published literature has revealed Kimura’s disease cases that mimic dumbbell neurogenic tumors. Here, we report such a case of Kimura’s disease for the first time and provide a brief review of the literature.

Kimura's disease: effects of age on clinical presentation

BACKGROUND

Kimura's disease (KD) is known to be dominant among young Asian men, but it can also occur in middle- and advanced-aged people. The clinical characteristics of KD, especially by age, are not well known.

AIM

This study was performed to investigate the effects of age on the clinical characteristics of KD.

DESIGN

We conducted a case series study.

METHODS

All case studies of patients diagnosed with KD were collected via a PubMed search of studies published until August 2018. The data were analyzed by age group.

RESULTS

In total, 215 studies were reviewed (238 patients; mean age of 36 years). The male:female ratio was 4:1 overall, 17:1 in patients aged <20 years, 4:1 in patients aged 20-39 years and 2:1 in patients aged ≥40 years (P = 0.01). The percentage of patients with pruritus was 15.4% overall, 3.8% in patients aged <20 years, 15.5% in patients aged 20-39 years and 21.7% in patients aged ≥40 years (P = 0.02). The time to diagnosis was 5.3 years overall, 3.2 years in patients aged <20 years, 4.7 years in patients aged 20-39 years and 7.1 years in patients aged ≥40 years (P < 0.01).

CONCLUSIONS

The proportion of female patients affected the incidence of pruritus, and the time to diagnosis increased as the patients' age increased. There were no significant age-related differences in region/race, complications, multiplicity, laterality, anatomical distribution, maximum size, eosinophil count, immunoglobulin E level, initial treatment, recurrence or outcomes. This may be useful information for the diagnosis of KD.

Kimura's disease of the right cheek: A case report

Kimura's disease (KD), a chronic inflammatory disease of uncertain etiology, manifests as a painless subcutaneous swelling in the head and neck region that involves major salivary glands and regional lymph nodes. To date, the majority of cases of KD have been documented in Asian males aged 20-30 years. However, the number of reported cases of KD involving the oral and maxillofacial area is limited, and since the masses appear similar to cysts or benign tumors, the establishment of an accurate pre-operative diagnosis is challenging. The accurate diagnosis of KD is considered to require surgical excision followed by histopathological examination. In the current case, a 39-year-old man was admitted to hospital in October 2011 with a swelling evident on his right cheek. Surgical excision was performed, and histopathological observation was carried out. The formation of a lymphoid nodule accompanied by the vigorous proliferation of small blood vessels, eosinophilic infiltration and thickened cell walls were observed. No sign of recurrence of the mass has yet been observed, on the basis of the telephone follow-up interviews. These findings provide a novel insight useful in the diagnosis of KD in the oral and maxillofacial area.

Successful treatment of recurrent Kimura's disease with radiotherapy: a case report

Kimura's disease is a rare, chronic inflammatory disorder affecting the skin and subcutaneous tissue, predominantly in the head and neck region. It is benign but may be recurrent and difficult to eradicate. A case of recurrent Kimura disease in a 53-year-old man was reported. Radiation therapy was performed for recurrence after surgical excision twice. The prescribed radiation dose was 36 Gy. With a follow-up time of 68 months, the patient was free of the disease.
