RESUMEN
Kimura's disease (KD) is a rare lymphoproliferative fibroinflammatory disorder that commonly affects the subcutaneous tissue and lymph nodes of the head and neck. The condition is a reactive process involving T helper type 2 cytokines. Concurrent malignancies have not been described. Differential diagnosis with lymphoma can be challenging without tissue biopsy. Here, we present the first reported case of coexisting KD and eosinophilic nodular sclerosis Hodgkin lymphoma of the right cervical lymphatics in a 72-year-old Taiwanese man.

BACKGROUND: Kimura's disease is a rare, benign, chronic inflammatory disease that presents as painless, solid masses mainly affecting the deep subcutaneous areas of the head and neck, especially the salivary glands, parotid glands and nearby lymph nodes. It is characterized by elevated peripheral blood eosinophil and Immunoglobulin E (IgE) levels. CASE PRESENTATION: A 31-year-old Asian male presented with an orbital space-occupying lesion lasting for 1.5 years. Ten years prior, surgical excision of bilateral fossa cubitalis and groin masses was performed, and the pathological examination showed "lymphoproliferative disease". One year later, masses reappeared near the surgical sites; they grew slowly and shrank after glucocorticoid treatment. At this point, admission examinations showed in the peripheral blood an eosinophil proportion of 13.4%, a total IgE level of 26,900.00 IU/mL, prurigo present on the whole body, and multiple palpable masses near the bilateral fossa cubitalis and groin. The left eyeball was exophthalmic. The left elbow mass was excised, and the pathological examination confirmed Kimura's disease. Oral glucocorticoid therapy is taken and tapering regularly. The eosinophil count returned to normal, the IgE level gradually decreased, the orbital space-occupying lesion and elbow and groin masses shrank significantly, and the whole-body skin prurigo disappeared. Currently, the patient has been in a stable condition for eighteen months. CONCLUSION: Our case provides a novel insight that Kimura's disease should be involved in the differential diagnosis of inflammatory lesion mass of orbit and also supports systemic regular glucocorticoid as a valuable therapy of such condition, but close follow-up and long-term observation are crucial.

Ultra-rare diseases occur with a frequency of 2 in 100 000 people or less. Kimura's disease (KD) affects less than 1 in 1 000 000 people. It is a benign, chronic inflammatory soft tissue disorder, accompanied by eosinophilia, raised immunoglobulin E (IgE) titer and the presence of painless subcutaneous masses, usually in the head and neck region. The disease was first described in 1948 and occurs at higher rates in Asia than in America or Europe. A CASE REPORT: A 35-year-old man without past medical history presented to his family doctor for bilateral cervical lymphadenopathy accompanied by eosinophilia. Despite subsequent in-depth diagnostics, including fine-needle aspiration biopsy (FNAB) of the lymph nodes, the definitive diagnosis was not initially established. After following 2 months, a selective lymphadenectomy was performed, putting Hodgkin's lymphoma under suspicion. The image of positron emission tomography coupled with computed tomography (PET-CT) corresponded to this diagnosis. Due to the lack of all the criteria necessary to make a diagnosis, another histopathological consultation was done. The image of the lymph nodes suggested reaction-inflammatory changes. Due to the presence of a triad of signs (reactive lymphadenopathy, several eosinophils in the paracortic zone, vascular proliferation), differential diagnosis was recommended, among others towards the Kimura's disease. A series of examinations allowed to exclude lymphadenopathy of parasitic, allergic and hyperplastic hematopoietic system aetiology. The patient started steroid therapy with a good effect at first. However, after the recurrence of the disease, the patient was qualified to intensify the immunosuppressive treatment. CONCLUSIONS: In the described case, the intensive diagnostic process and the thorough analysis of the test results relatively quickly led to the correct diagnosis. This enabled the implementation of appropriate treatment and prevented the initiation of empirical therapy for the originally diagnosed Hodgkin's lymphoma.

AIMS: To compare the fibroinflammatory diseases Kimura's disease (KD) and immunoglobulin (Ig)G4-related disease (IgG4RD) and to explore their possible relationship. METHODS AND RESULTS: Forty-six cases of KD and 29 IgG4RD from our institution diagnosed from 2011 to 2020 were studied. They were compared with each other on clinical, pathological and immunohistological features. There were similar clinical features, except that IgG4RD affected an older patient population, with more frequent salivary gland involvement and KD affected head and neck lymph nodes, and showed blood eosinophilia more frequently than IgG4RD. IgG4RD exhibited frequent storiform fibrosis and obliterative phlebitis, while KD showed more frequent tissue eosinophilia, eosinophilic abscess, germinal centre eosinophilic deposit and vascularisation. Twenty to 30% of KD had more than 50 IgG4+ plasma cells (PC) per high-power field (HPF) and IgG4/IgG+ PC ratio exceeding 40%. These parameters, however, occurred in 100% of IgG4RD. Significantly more KD had >10 IgE+ PC/HPF and lymphoid germinal centre IgE reticular staining compared to IgG4RD. All these histological and immunohistological features are overlapping in the two diseases, although they differed with statistical significance. CONCLUSION: Our study confirmed that there is significant overlap in clinical, pathological and immunohistological features between KD and IgG4RD. It is important to recognise these overlapping features, and correlation with a clinicopathological picture is required in differential diagnoses. The overlapping features also suggest a possible close relationship between KD and IgG4RD, which could represent different facets of a continuous fibroinflammatory disease spectrum.

BACKGROUND: Kimura's disease (KD) is a rare chronic inflammatory disease and the etiology remains uncharacterized. The typical manifestations are painless lymph node or subcutaneous masses. There is currently no report of prominent renal interstitial injury and cardiac insufficiency in KD. CASE PRESENTATION: A 45-year-old man was referred to our hospital with dark urine, subcutaneous masses in forehead and right retroauricular, multiple lymphadenopathy and unexplained cardiac insufficiency. Renal biopsy demonstrated eosinophilic interstitial nephritis. Laboratory tests revealed eosinophilia and a high level of serum IgE. A biopsy of cervical lymph node was performed and KD was diagnosed. Treatment with oral prednisone resulted in a decrease of eosinophil, serum IgE, improvement of cardiac function, and regression of the subcutaneous mass. CONCLUSIONS: We describe an extremely rare KD case presenting with eosinophilic interstitial nephritis, cardiac insufficiency and significant response to prednisone. The clinicians should improve the disease awareness and find optimal treatment.

BACKGROUND: Eosinophilic peritonitis is a relatively rare entity. Kimura's disease is a rare chronic inflammatory disorder of unknown etiology, characterized by subcutaneous nodules mainly in the head and neck region, regional lymphadenopathy and occasional involvement of kidney. There is currently no report of eosinophilic peritonitis in Kimura's disease. CASE PRESENTATION: A 44-year-old Chinese man presented with abdominal distention, nausea, vomiting and edema in lower limbs for 1 month. Laboratory data showed elevated eosinophils in peripheral blood and ascites, nephrotic syndrome with progressively renal dysfunction, and elevated IgE. Ultrasonography of lymph nodes showed multiple lymphadenopathy in bilateral inguinal regions. Surgical excision was performed for one of the enlarged lymph nodes and histopathology revealed diagnosis of Kimura's disease. Renal biopsy indicated focal segmental glomerulosclerosis (FSGS) and acute tubulointerstitial nephritis with infiltration of eosinophils in renal interstitium. The patient was prescribed with oral prednisolone therapy (30 mg/day), and underwent continuous ambulatory peritoneal dialysis (CAPD). The peripheral and peritoneal eosinophil count decreased rapidly and normalized within 2 days. Forty-five days after prednisolone therapy, partial remission of nephrotic syndrome and decrease of serum creatinine were achieved while peritoneal dialysis dosage had decreased. Inguinal lymph nodes gradually shrunk in size. The overall conditions remain stable afterwards. CONCLUSIONS: This rare case highlighted the clinical conundrum of a patient presenting with eosinophilic peritonitis, lymphadenopathy, nephrotic syndrome and renal failure associated with Kimura's disease. The remarkable eosinophilia, pathology of lymph node and kidney, as well as significant response to steroids should guide towards the diagnosis.

BACKGROUND: When we encounter patients who present with both a neck mass and nephrotic syndrome, both malignancy and Kimura's disease need to be evaluated as the therapeutic strategies differ vastly between them. CASE PRESENTATION: We present the case of a 27-year-old male patient with neck mass and nephrotic syndrome. The presence of both eosinophilia and elevated immunoglobulin E levels were concerning for Kimura's disease, which is an allergic syndrome defined by eosinophilic granulomas of neck soft tissue along with peripheral eosinophilia. The eventual final diagnosis, however, was sclerosing mucoepidermoid carcinoma of parotid gland with both eosinophilia and membranous nephropathy. Following the surgical resection of the mass, the nephrotic syndrome completely resolved. CONCLUSION: Detailed histopathological assessments of both the parotid gland and renal tissue were key aspects of the diagnosis and management to exclude Kimura's disease.

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 disease (KD) is a rare benign chronic inflammatory disease that presents as a nodule mostly involving deep subcutaneous tissue of the head and neck region with frequent regional lymphadenopathy and peripheral blood eosinophilia. KD shares some clinical and histopathological similarity with angiolymphoid hyperplasia with eosinophilia (ALHE). Consequently, KD and ALHE were once considered variants of the same disease spectrum. We present here rare cases of Kimura disease and ALHE involving the eyelid and lacrimal gland and discuss their differential features.

BACKGROUND: Kimura's disease is a rare chronic inflammatory disorder of unknown etiology that is seen in people of Asian descent. It is characterized by head and neck subcutaneous nodules along with lymphadenopathy, which is usually solitary but can be generalized. It is diagnosed histopathologically by the proliferation of blood vessels and germinal centers in lymphoid follicles, along with variable degrees of fibrosis and extensive eosinophil infiltration. Its localized form is treated with surgical excision, while generalized lesions and those that do not respond to surgical excision can be managed with steroids or radiotherapy. CASE: In this report, we present the first case of Kimura's disease in the Ethiopian literature in a 40-year-old Ethiopian man that presented with generalized pruritic subcutaneous nodules and lymphadenopathy, which were effectively managed with a tapering course of prednisolone, and a relapse that showed good sustained response with slow steroid taper. CONCLUSION: We have demonstrated that, even though it is very rare in the African continent, Kimura's disease is to be considered as a differential diagnosis for patients that present with subcutaneous nodules and lymphadenopathy. We also have demonstrated that relapses can be effectively managed with reinitiation of the same dose of steroids but with a very slow taper.

Kimura's disease (KD) is a chronic inflammatory disorder characterized by nontender lymphadenopathy involving the head and neck region. Renal involvement in KD is rare, especially in children. We report a 12-year-old boy who had been previously treated for classical KD and had presented with anasarca and oliguria after 4 years. There were no swellings or lymphadenopathy. The kidney biopsy revealed membranous nephropathy. Remission was achieved with oral prednisolone and tacrolimus therapy. This patient highlights the need to regularly monitor patients with KD for the evolution of renal diseases, even if lymphadenopathy regresses. Serial monitoring for eosinophilia, inflammatory markers, and urine examination is needed to help identify subclinical disease early and prompt initiation of specific therapy.

Introduction: Kimura's disease (KD) is a rare chronic inflammatory disorder characterized by subcutaneous lymphoid hyperplasia with peripheral eosinophilia. Kidney involvement is reported in 15%-18% of adult patients with KD, in many cases as nephrotic syndrome. We present a case of overlapping membranous nephropathy and IgA nephropathy associated with KD. Case report: A 27-year-old man was admitted with a history of bilateral leg edema for the last 2 months and concomitant progressive increase of cervical mass and fever. Laboratory findings were as follows: peripheral leukocyte count, 10,080/mm³; eosinophils, 3,200/mm³ (31.7%); serum creatinine, 0.83 mg/dL; and eGFR: 140 mL/min per 1.73 m2. Urinalysis revealed the presence of hematuria and proteinuria and the following results: 24-h proteinuria, 12.9 g; serum albumin, 1.3 g/dL; and elevated IgE level, 750 kU/L. Serologies for hepatitis B, hepatitis C, HIV, and VDRL were all negative. Complement C3 and C4 levels were normal. No monoclonal protein was detected in blood and urine. Parasite infestation was discarded. A biopsy of the cervical lymph node revealed eosinophilic lymphoid hyperplasia, suggesting KD. A kidney biopsy revealed findings consistent with the overlapping of membranous nephropathy with IgA nephropathy. The patient was treated for KD with prednisone 1 mg/kg/d with progressive dose tapering and posterior association of methotrexate 15 mg/week. A renin-angiotensin system inhibitor was prescribed for nephrotic syndrome. The cervical mass regressed, and proteinuria achieved partial remission, with an increase in serum albumin level and normalization of eosinophils and IgE levels. Conclusion: Although uncommon, kidney involvement must be considered in patients with KD. Glomerular diseases are the most frequent form of kidney injury.

Kimura's disease is a chronic, benign inflammatory condition of the subcutaneous tissue. It presents as painless, subcutaneous nodules of the head and neck, which are firm, painless, and may be single or multiple. It is most commonly seen in young adult Asian men. The nodes remain stable or may slowly enlarge over time. Elevated serum immunoglobulin E (IgE) levels, peripheral blood eosinophilia and lymphoid proliferation with eosinophilic infiltration on histopathological examination are the characteristic features. Spontaneous regression is usually seen. The diagnosis of Kimura's disease can be difficult and misleading, and it is important not to ignore histopathological features.

BACKGROUND/AIM: Kimura's disease is a rare chronic inflammatory disorder that commonly affects the head and neck regions, occurring predominantly in Asian men. Elevated eosinophil count and IgE levels in the peripheral blood examination are suggestive of this disease. In this study we report two cases of Kimura's disease, treated with wide excision. CASE REPORT: The first case was a 58-year-old man presented with asymptomatic left neck mass. The second case was a 69-year-old man with swelling of the right upper arm, which was suggestive of soft tissue mass. Needle biopsy results were suggestive of Kimura's disease in both cases. Elevated WBCs at 8,380/µl (neutrophils: 45%, eosinophils: 33%) for the first case and 5,370/µl (neutrophils: 61.8%, eosinophils: 3.5%) for the second one, and serum IgE at 14.988 IU/ml for the first case and 1,315 IU/ml for the second one were observ. For definitive treatment and diagnosis, wide excisions were performed. Final histopathological results revealed Kimura's disease. Surgical margins were negative even though an ill-demarcated lesion for the first case and high infiltration to the muscle for second case were confirmed. CONCLUSION: Wide excision was performed in both cases of Kimura's disease and no recurrence was observed until the final follow-up. Wide excision with negative surgical margin should be recommended for the treatment of Kimura's disease.

BACKGROUND: Warthin tumor (WT) is a common benign salivary tumor of the parotid gland. Clinically, it occurs in men in their fifth to seventh decades who typically smoke cigarettes. WTs have been reported with different head and neck neoplasms and other salivary gland tumors within the same or another salivary gland. Kimura disease (KD) is a rare chronic inflammatory disease with unknown etiology affecting young to middle-aged Asian men. KD presents as an asymptomatic nodule in the head and neck area, with regional lymphadenopathy and salivary gland involvement. CASE PRESENTATION: A 64-year-old Arabic man presented with a 10-year history of an asymptomatic swelling of the left face. Computed tomography showed a well-defined, multicystic mass with heterogeneous enhancement. The resected mass was composed of two distinct components. There was a well-demarcated proliferation of papillary and cystic oncocytic epithelium with lymphoid stroma, consistent with WT. Some areas exhibited sclerotic fibrosis, with multiple lymphoid follicles showing folliculolysis, follicular hyperplasia, and eosinophilic infiltrate. The patient's immunoglobulin E level serum was elevated, confirming a coexisting KD. The patient underwent a left superficial parotidectomy, with no recurrence at a 30-month follow-up. CONCLUSION: This report describes the first concurrent case of WT and KD in the parotid gland.

Kimura disease (KD) is a rare inflammatory disorder which involves the head and neck. Due to its rarity and various findings, definitive diagnosis can be difficult to ascertain. Kimura disease is distinguished from other conditions, including angiolymphoid hyperplasia, by histopathological features including follicular hyperplasia, reactive germinal centers, abundant eosinophilia, eosinophilic microabscesses, preserved nodal architecture, Warthin-Finkeldy polykaryocytes, and capsular fibrosis. Herein, we describe the clinical presentation, pathology, and diagnosis of a single case of a 39-year-old treated at an academic center in Texas.

Kimura's disease is a rare, benign entity that causes subcutaneous angioblastic lymphoid hyperplasia with eosinophilia. It usually presents with subcutaneous lymphoid swellings with regional lymphadenopathy and salivary gland masses. Kimura's disease is frequently associated with renal involvement, which includes proteinuria and nephrotic syndrome as the most common presentations. This report presents a case of a man in his early 20s with a swelling in the medial aspect of the distal left arm with two previous episodes of nephrotic syndrome. Multiple enlarged axillary lymph nodes and epitrochlear nodes were noted. Ultrasonography revealed a mixed echogenic mass with enlarged lymph nodes. MRI showed a heterogeneous hyperintense lesion. Image-guided fine-needle aspiration showed multiple lymphocytes and eosinophils suggestive of Kimura's disease. The swelling was surgically excised under general anaesthesia. Histopathology of the excised mass confirmed the diagnosis of Kimura's disease.

Kimura's disease (KD) is currently considered a rare chronic inflammatory disease of unknown etiology. It is more common in the Asian population, especially in young and middle-aged men, and can involve the lymph nodes, salivary glands, and subcutaneous tissues. It has been reported in adults and children, and is often accompanied by elevated peripheral blood eosinophils and elevated serum immunoglobulin E (IgE). Herein, we report a case of KD in a 46-year-old man with bilateral masses behind the ears since childhood that had gradually enlarged over 40 years. The patient's peripheral blood eosinophils were elevated, and interestingly, homocysteine levels were also elevated. After surgical resection of the bilateral posterior auricular masses, follow-up over 5 years indicated good recovery and no signs of recurrence.
