Kimura's disease is a rare, benign, slow-growing chronic inflammatory swelling with a predilection for the head and neck region and is almost always with peripheral blood eosinophilia and elevated serum IgE levels. It is endemic in Asian males and rare in Western people. Surgical excision of the lesion is the first line therapy. Drug and radiation therapy have to be considered for the refractory lesions.

A 48-year-old middle aged male presented swelling lymph nodes and mass in neck for 5 years. Physical examination shows swollen mass in head and neck regions. The masses could be touched in bilateral parotids and neck with a little movement and moderate tenderness. The level of IgG was normal, but Eosinophi count was high. The function of heart liver and kidney was normal. The result of B-mode ultrasonography reveals bilateral parotids and subcutaneous near parotids were widely swollen and several swollen lymph nodes in neck. pathological examination displays features of a large number of lymph follicles hyperplasia, acidophilic granulocyte infiltration, capillary hyperplasia and fibrosis of different level. The disease were eventually diagnosed by pathological examination. Method of treatment includes glucocorticoid drug therapy, surgical resection and local radiotherapy. The last treatment of patients with Kimura's disease should be combined with the clinical manifestation of them to determine the individualized treatment, so as to improve the quality of life of patients.

A 35-year-old woman presented with history of a painless, slow-growing nodule in a left eye caruncle over the last 2 months. The visual acuity was 20 / 20 and the ocular movements were in the normal range. The venereal disease research laboratory test, erythrocyte sedimentation rate, serum angiotensin converting enzyme level, and chest radiograph were all normal. An excisional biopsy was done to confirm the diagnosis. A 1.3 x 0.5 x 0.3 cm sized nodule was extracted and sent for histopathologic examination. Hematoxylin-eosin staining showed follicular hyperplasia with perifollicular fibrosis, an eosinophil infiltrate, and proliferation of capillary vessels. The capillaries were lined by normal-appearing, flat, spindle-shaped endothelial cells. On the basis of these histopathologic findings, the diagnosis of Kimura disease in a caruncle was established. This is the first report describing Kimura disease localized to a caruncle. Kimura disease should be suspected and included in the differential diagnosis of a caruncular mass lesion.

OBJECTIVETo study the clinicopathologic features, diagnosis and differential diagnosis of epithelioid hemangioma.

METHODSThe morphologic features of 7 cases of epithelioid hemangioma of skin, bone and venous vessels were studied.

RESULTSThere were altogether 4 male and 3 female patients (median age = 34 years; age range from 14 to 54 years). The 3 skin cases presented as single or multiple erythematous to bluish nodules or papules, with or without itchiness. The 2 bone cases appeared as osteolytic expansile lesions on radiologic examination. The remaining 2 cases involved medium-sized venous structures and presented as small isolated nodules in soft tissue. Histologically, the lesions were characterized by the presence of exuberant endothelial proliferations with various degree of inflammatory reaction. The neoplastic endothelial cells were plump, eosinophilic and polygonal, forming vascular channels. Occasional solid sheet-like arrangement was demonstrated. Intracytoplasmic vacuoles were commonly identified, indicating formation of primary lumen. The surrounding stroma contained various number of eosinophils and lymphoplasmacytic cells. Immunohistochemical study showed that the tumor cells were positive for endothelial markers (CD31 and CD34) and negative for epithelial marker (cytokeratin). Follow-up information was available in 6 cases. The duration of follow-up ranged from 5 to 36 months (median = 14 months). There was no evidence of recurrence or distant metastasis.

CONCLUSIONSEpithelioid hemangioma is a rare benign curable lesion which can be multifocal, involving skin, soft tissue and bone. It needs to be distinguished from Kimura's disease and epithelioid hemangioendothelioma.

OBJECTIVE: To improve the diagnosis and treatment of Kimura's disease (KD) by investigating its clinical characteristics, pathological features and complications. METHOD: The clinical data of 33 cases of KD were analyzed retrospectively. RESULT: Of 33 cases, 22 showed the mass on head and neck, while in the other cases, the mass distributed in the region of groin, axillary fossa, hilum of lung and mesentery. Regional lymph nodes were involved in 21 cases and major salivary glands were invaded in 8 cases. Twenty-three cases had typical peripheral eosinophilia, although only in 2 patients the quantity of serum total IgE increased markedly. Urine abnormalities happened to 7 cases, such as massive proteinuria (3 cases) and hematuria (2 cases). Among 6 cases which underwent bone marrow aspiration, 2 showed eosinophilia. Two cases were complicated with nephritic syndrome. Six cases were combined with local inflammation on head and neck and 2 cases were combined with malignant tumor. CONCLUSION Mass on the head and neck is the typical clinical manifestation in KD, with regional lymph nodes and major salivary glands involved most. Serum total IgE and histopathologic examination should always be done to confirm KD, especially in the cases with unknown eosinophilia increasing.

Kimura's disease (KD) is a rare, chronic inflammatory disorder, which is characterized by tumor-like masses mainly located in the head and neck region. Extraocular muscle involvement in KD is uncommon. We report a case of KD that involved both the extraocular muscles and buccal area. A 13-year-old male presented to our clinic with a two-year history of exophthalmos of the left eye and facial swelling. Facial CT and MRI showed a 1.5 x 1.5 cm2 soft tissue mass located at the left masticator and buccal area, exophthalmos of the left eye, and diffuse thickening of the left extraocular muscles. We performed a lateral rectus muscle incisional biopsy of the left eye. Oral methylprednisolone therapy was initiated and tapered following the incisional biopsy.
