Combination of available topical beta-blockers and antibiotic ointment for epidermal growth factor receptor tyrosine kinase inhibitor-induced paronychia and pseudopyogenic granulomas in Taiwan.

BACKGROUND: Painful paronychia and pseudopyogenic granuloma (PG) are common adverse drug reactions (ADRs) associated with the use of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) to treat non-small cell lung cancer (NSCLC). Multiple local management approaches have been tested with unsatisfactory results. We have introduced an occlusion therapy technique through which available topical drugs for longer than 2 years. METHODS: Based on the cancer registry and case management system of our hospital, from July 2019 to July 2020, we retrospectively enrolled patients with NSCLC who were treated with EGFR-TKIs and received applications of 0.5% timolol ophthalmic solution (TIMOPTOL XE 0.5%®) combined with a neomycin/tyrothricin ointment (Biomycin®) using the occlusion method to treat paronychia or PG. RESULTS: A total of 22 patients were enrolled, with a mean age of 66.5 years, most of whom were women (72.7%). Periungual lesion-related pain was reported by all patients, and periungual bleeding and PG were reported in 14% (3/22) and 64% (14/22) of patients, respectively. After the occlusion therapy application of timolol ophthalmic solution combined with neomycin/tyrothricin ointment twice daily, the overall response rate was 83.3%, including complete response in 18% (4/22) of cases and partial response in 68% (15/22) of cases. CONCLUSION: We presented an occlusion method using available topical beta-blockers and antibiotic ointment for EGFR-TKI-induced paronychia and PG in Taiwan. The result is favorable. Further randomized control trial is urgent to validate our findings.

Kimura's disease: clinical characteristics, management and outcome of 20 cases from China.

OBJECTIVES: To explore the clinical characteristics, diagnosis and the therapeutic effect of Kimura's disease (KD). METHODS: Clinical data of 20 patients with pathologically confirmed KD admitted to Peking University People's Hospital from June 2000 to June 2019 were analysed. A total of 20 confirmed KD patients were enrolled in the study, 18 male and 2 female, with age-onset ranging from 2 to 58 years. RESULTS: The masses appear as focal, painless, and immovable with an unclear boundary. The most common predilection is head-neck region (n=15, 75%). 15 patients showed peripheral blood eosinophilia. 14 of 14 patients presented with increased serum IgE level. The prominent pathological characteristic is marked lymphoid hyperplasia accompanied by various degrees of vascular hyperplasia and eosinophil infiltration. Among the 20 patients, 12 experienced recurrence of disease after treatment (surgical resection alone: 9/9; oral corticosteroids combined with immunosuppressants: 1/3; surgical resection followed by oral corticosteroids combined with immunosuppressants: 2/6). CONCLUSIONS: KD should be considered when the patient presents with head-neck swellings and lymphadenopathy, accompanied by an increase of IgE and eosinophil. Compared with surgery alone, combined therapy seems to be a promising treatment option to reduce the recurrence rate.

A case of membranous nephropathy with Kimura's disease.

BACKGROUND: The association between membranous nephropathy (MN) and Kimura's disease (KD) has been reported in recent years. The treatment, effect, and prognosis of KD are still unclear. CASE REPORT: A 47-year-old KD patient developed a left axillary mass for 3 years and received surgical resection because of the lager mass in August 2016. Then he developed nephrotic syndrome 3 months later. Laboratory index revealed increased eosinophil count, decreased albumin and heavy proteinuria. Lymph node biopsy suggested KD, and renal biopsy suggested MN. He relapsed after a treatment with methylprednisolone (52 mg/d) alone and then tacrolimus (1.5 mg/12h) was added. The patient had no symptoms of relapse in the next 2 years. CONCLUSION: The combination therapy of surgery, methylprednisolone, and immunosuppressive agents may be effective in KD with MN.

Refractory angiolymphoid hyperplasia with eosinophilia: Complete resolution with low dose thalidomide.

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a difficult-to-treat and rare benign vascular proliferative condition which presents as painless, solitary, or multiple vascular papules or nodules in the head and neck area, with predilection for the ear. We report a case of ALHE that failed multiple therapeutic interventions but achieved complete resolution when treated with thalidomide.

[Kimura's disease. (Clinical case study)]. / Bolezn' Kimury. (Sobstvennoe nablyudenie).

The author presents his own observation of a patient with Kimura's disease (CD), which is a rather rare chronic inflammatory disease of soft tissues. The results of clinical examination and surgical treatment of this disease are presented. It is emphasized that for the diagnosis of CD, first of all, an excision biopsy of the lesion is necessary, as well as the presence of eosinophilia in the patient, an increased level of immunoglobulin E (IgE) in peripheral blood, an increase in regional lymph nodes.

[Immune thrombocytopenia associated with Kimura's disease].

In this study, we report a rare case of immune thrombocytopenic purpura (ITP) associated with the worsening of Kimura's disease. A 47-year-old Japanese man with a pruritic rash and swollen inguinal lymph nodes was diagnosed with Kimura's disease on performing a right inguinal lymph node biopsy. Thrombocytopenia ensued after the diagnosis of Kimura's disease, and fluctuations in the platelet count were observed along with the pathology of Kimura's disease. The platelet count fluctuated repeatedly with the relapse of Kimura's disease and a diagnosis of a combination of Kimura's disease and ITP was made through lymph node regeneration and bone marrow examination. Treatment with prednisolone (1 mg/kg/day) was initiated for Kimura's disease and ITP, and lymphadenopathy and platelet count improved promptly. Since then, the dose of prednisolone has been gradually reduced, and the disease status of both Kimura's disease and ITP has been controlled.

VEGF-A Links Angiolymphoid Hyperplasia With Eosinophilia (ALHE) to THSD7A Membranous Nephropathy: A Report of 2 Cases.

Autoantibodies against thrombospondin type 1 domain-containing 7A (THSD7A) cause membranous nephropathy (MN); however, the mechanisms involved in THSD7A expression and immunization are uncertain. We present 2 cases of THSD7A-associated MN accompanied by angiolymphoid hyperplasia with eosinophilia (ALHE), a benign tumor characterized by proliferation of plump endothelial cells. Prednisolone therapy, but not surgical resection of ALHE tumors, successfully suppressed eosinophilia and proteinuria in both cases. Because ALHE is characterized by the proliferation of plump endothelial cells, we focused on the roles of vascular endothelial growth factor A (VEGF-A) in MN pathogenesis. We found that plump endothelial cells in ALHE modestly expressed THSD7A in both cases. We also found that eosinophils in ALHE expressed VEGF-A, which upregulated THSD7A expression, especially under T-helper type 2-prone conditions in cultured endothelial cells. Furthermore, double-positive cells for THSD7A and CD83 surrounded the proliferated small vessels. Our results suggest that VEGF-A-induced THSD7A expression outside the kidney may be important for MN pathogenesis.

Kimura's disease with membranoproliferative glomerulonephritis: a case report with literature review.

BACKGROUND: Kimura's disease is a rare disease and its etiology is still unclear. Here we reported a case with lymphadenopathy complicated with secondary membranoproliferative glomerulonephritis. CASE PRESENTATION: A 46-year-old Chinese man presented with bilateral tumor-like nodules over his neck during the past 6 months and developed edema for 15 days. His blood pressure was 145/90 mmHg, multiple 1 × 1 cm masses were found over bilateral post-auricular and submandibular areas, along with trace edema of the lower extremities. Laboratory data showed an increased peripheral eosinophil count at 3.66 × 109/L (50% of total leukocytes), with a 24-hour urine total protein of 8 g and a serum albumin of 19 g/L, and serum IgE of 2930 IU/ml (<100 IU/ml). The patient underwent renal biopsy, which revealed membranoproliferative glomerulonephritis with eosinophilic infiltration of the interstitium. Lymph node biopsy showed eosinophilic lymphoid follicular granuloma. Bone marrow biopsy showed no abnormalities. A diagnosis of Kimura's disease was then established. We started him on prednisone 60 mg/day (1 mg/kg), and tapered the dose to 55 mg/day 2 months later, followed by a gradual reduction of 2.5 mg every 2 weeks. Valsartan was given for blood pressure control. His neck nodules shrank after 2 weeks of treatment and complete renal remission was achieved 3 months later. No relapse occurred after follow-up for 31 months. CONCLUSION: Kimura's disease can present with bilateral neck nodules and nephrotic syndrome (membranoproliferative glomerulonephritis), and prednisone can be a suitable choice of treatment.

Angiolymphoid Hyperplasia With Eosinophilia: New Concept to Lower Recurrence.

Angiolymphoid Hyperplasia with Eosinophilia (AHLE) is a rare benign vascular disorder of unknown etiology. While World Health Organization recognizes it as a benign neoplasm, its progressive nature and high recurrence rate are consistent with being a locally malignant tumor. It may present as solitary or multiple nodules with more predilection to head and neck region, especially auricular area. Despite variety of available treatment options, high recurrence rate remains a compelling issue. The spectrum of these treatment modalities includes topical or systemic steroids use, intralesional injection of certain materials such as Bleomycin, Vinblastine or interferon, or even surgical excision.In our study, the authors present a case of middle-aged female with recurrent AHLE in left concha and preauricular region. Excision of the lesion with 4 mm of the normal surrounding skin, preserving auricular cartilage, was done while the resultant defect was covered by grafted Temporoparietal Fascia Flap. Our 1-year follow-up period showed aesthetically accepted outcome with no recurrence.The authors hypothesize that treating AHLE as a locally malignant tumor by excising the lesion with 4 mm safety margin decreases recurrence rates. Moreover, reconstruction by grafted temporoparietal fascia flap achieves a reasonable aesthetic outcome with minimal donor site morbidity.

Clinicopathological features and prognosis of Kimura's disease with renal involvement in Chinese patients.

AIMS: Kimura's disease (KD) with renal involvement is a rare disease. Optimal treatments are still not well established. It is necessary to analyze clinicopathological features, treatment responses, and prognosis for improving KD diagnosis and treatment. MATERIALS AND METHODS: Clinicopathological data, treatment responses, and prognosis were collected and analyzed retrospectively. RESULTS: The patients consisted of 27 males and 2 females, with an average age of 35.5 ± 15.1 (13 - 61) years. 27 exhibited proteinuria ranging from 0.730 to 14.1 g/24 h (5.98 ± 3.40 g/24 h). Hypertension, renal insufficiency (serum creatinine (Scr) > 1.24 mg/dL), and microhematuria occurred in 4 (13.8%), 11 (37.9%), and 13 (44.8%) cases, respectively. Light microscopy (LM) identified mesangium proliferation, minimal change, focal and segmental glomerulosclerosis (FSGS), membranous glomerulonephritis, membranoproliferative glomerulonephritis (MPGN), and acute tubular necrosis in 14, 8, 3, 2, 1, and 1 cases, respectively. All were treated with Tripterygium wilfordii (TW), prednisone, leflunomide (LEF), tacrolimus (FK506), myophenolate mofetil (MMF), or renin-angiotensin system blockers (RASI). 26 patients were followed up for 1.60 - 108.7 months (39.6 ± 28.7). After treatments, urinary red blood cells (RBC) decreased in all. The amount of 24-hour urinary protein (24-hUPE) decreased in 24 patients. 22 reached complete remission (CR), 4 partial remissions (PR). The patients who did not relapse were younger than those who relapsed. CONCLUSIONS: KD with renal involvement occurs predominantly among 35 - 50 year old Chinese patients with male predilection. The most common features are proteinuria, hypertension, micro hematuria with minimal change, and mesangial proliferative glomerulonephritis. Most were responsive to treatment, but could relapse. Gender, age, and hypertension are associated with KD recurrence. The prognosis is good mostly.

Oral Propranolol as an Alternative Therapy for Orbital Angiolymphoid Hyperplasia With Eosinophilia.

An 8-year-old female patient presented with left upper eyelid swelling and erythema. Magnetic resonance imaging revealed an orbital mass involving the left lacrimal gland with subsequent incisional biopsy leading to the diagnosis of angiolymphoid hyperplasia with eosinophilia. Initially prescribed an oral corticosteroid, alternative management was sought after 4 months due to unwanted side effects of steroid therapy. Oral propranolol (2 mg/kg/day) was initiated with concurrent steroid taper. Interval decrease in lesion size was observed on subsequent magnetic resonance imaging with complete resolution of subjective symptoms (Fig. 1). She remains stable 14 months after starting beta-blocker therapy. To our knowledge, our case is the second case report suggesting oral beta-blocker may be an alternative therapy for orbital angiolymphoid hyperplasia with eosinophilia.

Diagnosis and treatment of a patient with Kimura's disease associated with nephrotic syndrome and lymphadenopathy of the epitrochlear nodes.

BACKGROUND: Kimura's disease (KD) is a slowly progressing rare, benign inflammatory disorder of the soft tissues. It typically presents as subcutaneous tumor-like nodules, located most frequently in the head and neck region. KD is often accompanied by increased peripheral eosinophilia and elevated levels of serum immunoglobulin (Ig) E. There is renal involvement in approximately 12-16% of KD cases. We report the case of a 23-year-old Chinese man who was found to have KD associated with nephrotic syndrome. CASE PRESENTATION: A 23-year-old Chinese man presented with edema in both legs and a mass in ulnar side of his right upper arm on August 8(th) 2013. Before admission to our hospital, an ultrasound examination revealed swollen lymph nodes in the medial aspect of his right upper arm, proximal to the elbow. The patient was admitted on August 19(th) 2013 as a result of edema, severe proteinuria, and low serum albumin levels. He had a white blood cell count of 7.7 × 10(9) cells/L, 48.5% eosinophils, 4+ albuminuria, 24-hour urinary protein excretion 9.3 g, serum protein 50.3 g/L; serum albumin 16 g/L and IgE 1,510 IU/ml. A biopsy of the epitrochlear nodes revealed eosinophilic hyperplastic lymphogranulomatous tissue. A renal biopsy indicated focal segmental glomerulosclerosis (FSGS) (cellular variant) with no infiltration of eosinophil in renal interstitium. The results of immune-staining on the renal biopsy were negative for IgG, IgA, IgM, C3 and C1q. The electron microscopic analysis showed podocyte effacement. His final diagnosis was Kimura's disease associated with nephrotic syndrome. He received methylprednisolone therapy as well as symptomatic treatment, and was discharged with key indicators in normal range on September 17(th) 2013. During the year following, he had methylprednisolone at a maintenance dose of 8 mg/day, and no relapses occurred up to now. CONCLUSION: Methylprednisolone therapy is effective in KD associated with nephrotic syndrome, and long-term administration of methylprednisolone at maintenance dose may be a way to prevent relapses of KD.

[Treatment of angiolymphoid hyperplasia with eosinophilia (ALHE) using topical tacrolimus: Two cases]. / Traitement de l'hyperplasie angiolymphoïde avec éosinophilie (HALE) par le tacrolimus topique : deux observations.

BACKGROUND: Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare disease, currently considered a benign vascular proliferation of unknown etiology, and whose treatment is still unclear and challenging. PATIENTS AND METHODS: Two women in their thirties consulted for itchy lesions of the right ear. Both presented with a reddish bleeding papulonodular infiltration of the auricle, with a nodule at the entrance to the external auditory canal in the first patient. Laboratory tests showed no abnormalities and in particular no hypereosinophilia or elevated serum immunoglobulin E. In both cases, histology of lesional skin showed vascular proliferation with thick-walled vessels lined by plump endothelial cells, protruding into the lumen, together with a mixed dermal inflammatory infiltrate consisting primarily of eosinophils and lymphocytes. A diagnosis of ALHE was made in both patients based on clinical and histological features. MRA revealed no underlying vascular malformation in both cases. Patients started treatment with 0.1% tacrolimus ointment twice daily. The pruritic sensation and bleeding had completely subsided within two weeks and the reddish infiltration and nodules had practically disappeared after two months of topical tacrolimus. Continuous application resulted in no recurrence at 6 months of follow-up. DISCUSSION: Treatment of ALHE is still poorly standardized due to doubts concerning the pathophysiology of this rare condition and the small number of available studies. Topical tacrolimus was originally developed for the treatment of moderate to severe atopic dermatitis because of its anti-inflammatory and immunomodulatory properties. Recent studies suggest that this drug may be effective in treating other forms of inflammatory dermatosis. Our two observations suggest that tacrolimus ointment also represents potentially valuable treatment in AHLE.

Propranolol: a novel treatment for angiolymphoid hyperplasia with eosinophilia.

Angiolymphoid hyperplasia with eosinophilia (ALHE) is an uncommon, idiopathic disease that manifests as dermal or subcutaneous red or brown papules or nodules, most commonly on the head and neck. Histologically, ALHE is characterized by vascular proliferation with epithelioid endothelial cells with surrounding lymphocytic and eosinophilic infiltrate. There may be an accompanying serum eosinophilia and local lymphadenopathy. We report a case of a 32-year-old woman who presented with multiple erythematous nodules in the periauricular area and the vertex of her scalp. The nodules had been present for several months. Surgical removal of one of the lesions confirmed the histological diagnosis of ALHE. The patient was started on oral propranolol (40 mg once daily) in an effort to reduce the vascular component of the lesions. Within 6 weeks, the patient noted that several of the lesions had decreased in size, and all were less erythematous. Propranolol was subsequently stopped within a few months of initiating treatment. One lesion recurred over a year later, and propranolol was then restarted. No new lesions occurred after 2 years of follow-up.

Kimura disease complicated with bowel infarction and multiple arterial thromboses in the extremities.

Kimura disease (KD) is a chronic inflammatory disease characterized by slowly growing subcutaneous nodules in the face and the neck region. Although a concomitant hypercoagulable state can accompany KD, massive thromboses in patients with KD have rarely been reported. Here, we report a case of KD complicated with bowel infarction and multiple arterial thromboses in the upper and lower extremities. The patient underwent bowel resection and was successfully treated with corticosteroid and anticoagulation.

A stepwise multimodality treatment of diffuse angiolymphoid hyperplasia of the orbit.

The definite treatment of angiolymphoid hyperplasia is debatable. We report the case of a middle-aged man with an extensive angiolymphoid hyperplasia of the orbit that has been recalcitrant to multiple single-line treatments for 9 years. His previous treatment included several short courses of full-dose systemic steroids, debulking surgeries, and orbital radiotherapy. A stepwise multimodality treatment approach in this case could achieve a lasting satisfactory functional and cosmetic outcome.

Anti-immunoglobulin E provides an additional therapy to conventional steroids for Kimura's disease.

Kimura's disease (KD) is a chronic inflammatory disease characterized by painless subcutaneous head and neck swelling, eosinophilia, and elevated serum immunoglobulin (Ig) E levels. There are various therapies, including surgery, radiation, systemic steroids, and immune suppressants, but their efficacy remains moderate due to the high recurrence rate. Biologics, like monoclonal antibodies, have shown tremendous effectiveness for chronic inflammatory diseases. Omalizumab is a monoclonal antibody against IgE and has not been approved for KD so far. We describe two refractory KD cases that responded to a small dose of steroids plus omalizumab. Additionally, we reviewed another 13 KD cases that were treated with biologics, including omalizumab, rituximab, dupilumab, and mepolizumab. The results indicate that biologics provide an alternative treatment strategy for KD.

Kimura's disease: a case report.

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.
