RESUMO

Evans Syndrome (ES) is a rare autoimmune disorder characterized by the simultaneous occurrence of immune thrombocytopenia (ITP) and autoimmune hemolytic anemia (AIHA). Thrombotic complications in ES patients are uncommon, particularly involving Buerger's Disease (BD). We report a case of a 49-year-old male with ES and a history of diabetes and heavy smoking, presenting with a necrotic wound on his right great toe. Diagnostic evaluations revealed severe stenosis and thrombosis in the lower limb arteries, diagnosed as BD. The patient underwent successful popliteal-tibioperoneal artery bypass surgery and the subsequent disarticulation and revision of the distal phalanx, followed by the application of an acellular dermal matrix (ADM) to promote healing. Post-surgery, the patient showed significant improvement in blood flow and complete epithelialization without complications. This case highlights the importance of a multidisciplinary approach to managing complex wounds in ES patients, suggesting potential treatment pathways for future cases involving BD.

RESUMO

Neurofibromas, rare benign tumors of the peripheral nerve sheath, present diagnostic challenges, particularly in diabetic patients with toe ulcers. This case involves a 55-year-old female with type 2 diabetes mellitus who developed an enlarging ulcer on her right second toe. The initial evaluation suggested a diabetic ulcer; however, advanced imaging revealed a mass-like lesion. Partial excision and biopsy confirmed a neurofibroma with spindle cells within the myxoid stroma and S100 protein expression. One month later, total excision and Z-plasty reconstruction were performed under general anesthesia. The patient's postoperative recovery was uneventful, and the patient was discharged without complications. Follow-up revealed successful healing with no recurrence or functional issues. This case highlights the importance of considering neurofibromas in the differential diagnosis of diabetic toe ulcers to avoid misdiagnosis and ensure appropriate management.

RESUMO

Diabetes mellitus (DM) causes various complications over time, one such complication is diabetic foot ulcers (DFU), which are challenging to treat and can lead to amputation. Additionally, a system for accurate prediction of amputation has yet to be developed. In total, 131 patients were included in the study after retrospectively collecting data from 2016 to 2020 about DFU. The collected data were used for comparison of the accuracy between five existing classification systems and the newly revised DIRECT coding system, and investigation of risk factors for lower extremity amputation (LEA). The existing five classification systems and DIRECT system can effectively predict LEA. The DIRECT3 system has three elements, C-reactive protein (CRP), ulcer history (UH), and hypertension (HTN) in addition to those of the DIRECT system. It had a high predictive value and accuracy similar to that of Wagner and University of Texas (UT) on depth among the five classification systems. Among the statistically significant risk factors, duration of DM and HTN, haemoglobin (Hb), CRP, and UH showed an association with LEA. The DIRECT coding system is effective for predicting LEA and explaining appropriate treatment methods for DFU, and is widely applicable because of its user accessibility and convenience.

RESUMO

Treating a diabetic foot ulcer (DFU) extending to the tendon or bone can be a challenge for physicians. Recent studies have shown positive results of micronized acellular dermal matrix (ADM) treatment for treating DFU. However, studies on such ADM with a long-term follow-up are rare. Thus, the objective of this study was to retrospectively analyse patients treated with micronized ADM with a long-term follow-up to assess the effectiveness of the treatment and determine the recurrence rate. The rate of success of complete healing was 62.96% and the time of complete healing was 86.96 days in this study. The recurrence rate of DFUs was 41.17% in the overall group. However, it was only 23.52% in the micronized ADM group. The average duration of recurrence was 720.50 ± 505.12 days. The recurrence rate was 50% in weight bearing areas such as the plantar and heel. It was 12.5% in toes and non-weight bearing areas. In conclusion, micronized ADM can be used to effectively treat DFUs that have invaded ligaments or bones. A close follow-up of weight bearing area wounds will allow us to identify and treat recurrence early.

RESUMO

The increased peripheral arterial disease (PAD) incidence associated with aging and increased incidence of cardiovascular conditions underscores the significance of assessing lower limb perfusion. This study aims to report on the correlation and utility of two novel non-invasive instruments: transcutaneous oxygen pressure (TcPO2 ) and forward-looking infrared (FLIR) thermography. A total of 68 patients diagnosed with diabetic foot ulcer and PAD who underwent vascular studies at a single institution between March 2022 and March 2023 were included. Cases with revascularization indications were treated by a cardiologist. Following the procedure, ambient TcPO2 and FLIR thermography were recorded on postoperative days 1, 7, 14, 21 and 28. In impaired limbs, TcPO2 was 12.3 ± 2 mmHg and FLIR thermography was 28.7 ± 0.9°C. TcPO2 (p = 0.002), FLIR thermography (p = 0.015) and ankle-brachial index (p = 0.047) values significantly reduced with greater vascular obstruction severity. Revascularization (n = 39) significantly improved TcPO2 (12.5 ± 1.7 to 19.1 ± 2.2 mmHg, p = 0.011) and FLIR (28.8 ± 1.8 to 32.6 ± 1.6°C; p = 0.018), especially in severe impaired angiosomes. TcPO2 significantly increased immediately post-procedure, then gradually, whereas the FLIR thermography values plateaued from day 1 to 28 post-procedure. In conclusion, FLIR thermography is a viable non-invasive tool for evaluating lower limb perfusion based on angiosomes, comparable with TcPO2 .

RESUMO

ABSTRACT: Blow-out fracture is usually caused by direct traumatic events in the periorbital area. But in this case, the authors introduce a case in which the medial orbital wall was fractured directly through the medial rectus muscle by high pressure air gun.A 38-year-old man was injured in his right periorbital area after being hit by high pressure air gun. He had mild ecchymosis and subconjunctival hemorrhage. He had a normal light reflex and intraocular pressure of 14 mm Hg. A facial computed tomography scan confirmed a blow-out fracture of the medial orbital floor with multiple extensive subcutaneous emphysema in the right hemifacial area. Free air was also seen near the basal cistern and Sylvian fissure, indicating a pneumocephalus. The operation was performed after swelling and emphysema were subsided. Intraoperative, medial rectus muscle was damaged. After the operation, no abnormal findings were observed in the ophthalmic examination. Also, the free air findings, which were observed in preoperative x-ray, have disappeared.This case is a rare case in which an orbital wall has been fractured directly through the medial rectus muscle due to an air gun injury. Therefore, we should always kept in mind that blow-out fractures can occur even with unusual mechanisms.

RESUMO

Necrotising fasciitis (NF) is a rapidly progressing fatal disease. Craniofacial necrotising fasciitis (CNF) is limited to the region above the mandibular margin, and early diagnosis is particularly difficult in the absence of related studies. Ten-year data of patients with craniofacial infection were collected from four separate hospitals. Based on the diagnostic criteria, patients were classified into abscess and CNF. The risk factors for early diagnosis were analysed by comparing the two groups. Simple abscess was found in 176 patients, and CNF was detected in 25 patients. The risk factors associated with CNF include old age, presence of odontogenic infection, elevated white blood cell count (WBC), increased C-reactive protein (CRP), high levels of creatinine (Cr) and glucose (Glu) and low levels of haemoglobin (Hb) and albumin (Alb). In addition, fever above 38°C and sinusitis at the time of admission and progressive sepsis after admission were also risk factors. Among the statistically significant risk factors, low Alb level showed the greatest association with CNF progression. Appropriate management of CNF via early diagnosis and extensive surgical intervention based on identified risk factors can reduce the mortality rate, complications and unnecessary medical expenses. Clinical question/level of evidence: Diagnostic, III.

RESUMO

The facelift is one of the most popular cosmetic surgery methods of antiaging. There are many complications in facelift, but infections rarely occur relatively. The authors would like to introduce a patient who developed infection after a facelift procedure. The cause of the infection was preauricular sinus, one of the congenital anomalies. The patient was treated with complete excision of sinus tract and the patient was treated without any further complications. Based on this clinical report, surgeons performing cosmetic surgery need to be interested in rare congenital lesions such as preauricular sinus.

RESUMO

Thread-lifting is as a minimally invasive procedure with limited scarring, rapid recovery, and fewer complications compared with the standard incisional surgery for facial rejuvenation. Using absorbable thread-like polydioxanone is a relatively simple procedure that is also performed by nonmedical professionals in Korea. Although several acute or delayed complications after using nonabsorbable thread types were also reported, it is uncommon to find cellulitis caused by a delayed complication after thread-lifting. A 41-year-old woman presented to our clinic with inflamed multiple palpable masses. She underwent 3 courses of acupoint embedding therapy at a Korean oriental medical clinic. She was treated with combination antibiotic therapy; however, the inflammation did not subside. Consequently, excisional biopsy was performed under local anesthesia. During the procedure, threads were detected and removed. Dimpling, thread exposure, alopecia, under-correction, asymmetry, and parotid gland injury also can occur as early complications of the procedure. Fortunately, these reactions are predominantly mild to moderate in intensity, and can be corrected by a relatively simple procedure. Chronic inflammatory reactions in the thread-lifting area, as identified in the authors' case, are an infrequent complication. It is recommended to consult with experts in the field for the implementation of this procedure. In addition, experts also need to notify the above side effects and solutions in advance to ensure safe and satisfactory procedures for their patients.

RESUMO

Human sparganosis is a food-borne zoonosis mainly caused by the plerocercoid belonging to the genus Spirometra. The most common clinical sign of sparganosis is a subcutaneous mass in the trunk including abdominal or chest wall. The mass may be mistaken for a malignant tumor, thereby causing difficulty in terms of diagnosis and treatment. A 66-year-old woman visited our clinic for the removal of a lipoma-like mass. It was movable, hard, and painless. We identified 2 white mass, measuring 0.2×4 cm and 0.2×1 cm. Pathologic findings indicated the white mass was a sparganum. She recalled having eaten a raw frog approximately 60 years before. A 35-year-old who lived North Korea was also presented to our clinic with an asymptomatic nodule on her abdomen. Intraoperatively, we found sparganum approximately 24 cm size. Subcutaneous masses are associated with clinical signs of inflammation or they may mimic a soft tissue neoplasm. While the incidence rate of sparganosis has decreased with economic development and advancements in sanitation, surgeons still encounter patients with sparganosis in the clinical setting. Therefore, a careful history is required in order to diagnose sparganosis.

RESUMO

Dermoid cysts are benign developmental anomalies that occurred as a result of the sequestration of the skin along the lines of embryonic closure. Those occurring in the cervicofacial region are uncommon, accounting for about 7% of all dermoids and its presence in postauricular region is further exceptionally rare. A healthy 19-year-old Asian boy presented with a unilateral postauricular cyst that had been present since childhood without any symptom. The computed tomography scan revealed an encapsulated tumor with no intracranial extension. Histological examination of a biopsy taken from the lesion revealed a unilocular cyst found in the deep dermis and subcutaneous tissue. Multinuclear giant cells and fragments of hair shaft are infiltrated in the cystic wall. Some keratin materials are seen in the intracystic area. However, the lining cells are not found. These histologic findings were suggested of the dermoid cyst. Patients with postauricular dermoid cysts usually seek medical advice for the cosmetic reasons because of the embarrassing look of the prominent unilateral or bilateral ears. The treatment of postauricular dermoid cyst is complete surgical excision of the cyst wall. Incomplete removal may result in recurrence or infection; thus, complete surgical excision is necessary. The prognosis is excellent without further complication.

RESUMO

A functional superficial parotidectomy can maintain salivary function by preserving the Stensen duct. However, this technique still brings the possibility of salivary leakage, because major branches of the parotid duct from the resected site do not get ligated. To reduce this complication, this study introduces a modified technique with major branch ligation. From December 2008 to February 2015, 14 patients who underwent superficial parotidectomy were divided into 2 groups. Group A was treated with the modified functional superficial parotidectomy involving the major branch between the superficial lobe and parotid duct. Group B was treated with the conventional superficial parotidectomy without involving the major branch of the parotid duct. The clinical complications, period of Hemovac usage, and surgical duration were noted in each group. Two of 8 patients in group A had a major branch from Stensen duct that was ligated, and there was no evidence of salivary leakage or sialocele in any of the patients of group A, whereas group B contained 2 cases of salivary leakage, one of which became sialocele. Group A had a significantly longer Hemovac maintenance period than group B (P < 0.05), and the duration of surgery was also significantly different between the 2 groups (P < 0.05). Because a solitary major branch of the main parotid duct occasionally extends toward the superficial lobe, our modified technique-functional superficial parotidectomy with ligation of the major branch toward the superficial lobe-is a useful option for treatment of a benign parotid mass in such cases.

RESUMO

Orbital cellulitis and abscess have been described in the literature as complication that usually occur secondary to infection in the maxillary, ethmoidal, and frontal sinuses. If left untreated, it can lead to blindness, cavernous sinus thrombosis, meningitis, or cerebral abscess. Orbital fractures are a common sequela of blunt orbital trauma, but are only rarely associated with orbital cellulitis. So, the authors present rare orbital cellulitis after orbital blow-out fracture. A 55-year-old Asian complains of severe orbital swelling and pain on the left side. These symptoms had started 2 days earlier and worsened within the 24 hours before hospital admission resulting in visual disturbances such as diplopia and photophobia. Contrast-enhanced computed tomography scan showed considerable soft tissue swelling and abscess formation on the left side. Patient was subjected to surgical drainage under general anesthesia in the operation room. In this case, the postoperative period was uneventful and the rapid improvement of symptoms was remarkable. In conclusion, the abscess of the orbit is a surgical emergency in patients whose impairment of vision or ocular symptoms cannot be controlled with medical therapy using antibiotics. In our case, orbital cellulitis can occur after blunt orbital trauma without predisposing sinusitis. Early and prompt diagnosis and surgical drainage before severe loss of visual acuity rescue or recover the vision in case of orbital cellulitis.

RESUMO

Chondroid syringoma is an unusual, benign skin appendageal tumor originating from the eccrine and apocrine sweat glands resembling mixed tumors of the salivary glands. It develops as a slow-enlarging, small, cutaneous nodule or mass. The lesions are usually seen in older men on head and neck. This is a clinical report of a 46-year-old lady who presented with a slowly growing nodular protruding mass in a cheek. The clinical and histologic findings of the tumor are demonstrated. The clinician and the pathologist should take into account the tumor among differential diagnosis not to overlook the lesion. Total surgical excision is needed with a long-term follow-up.

RESUMO

INTRODUCTION: Lipoma is the most familiar soft-tissue tumor. But the etiology of lipoma remains imprecise. Sex steroid hormones such as estrogen have effects on muscle and adipose tissue development. There is now significant evidence that sex steroids are involved in the site specificities of adipose tissue metabolism. This association of adipose tissue metabolism between sex steroid hormones suggests a possible role for sex steroids in the pathogenesis of lipoma. METHODS: To investigate this concept, the authors evaluated the expression of the estrogen receptor (ER) and the progesterone receptor (PR) in soft tissue lipoma in this study.In addition, angiogenesis and the production of angiogenic factors are fundamental for tumor progression in the form of growth, invasion, and metastasis. Epidermal growth factor receptor (EGFR) is involved in a signaling cascade that influences proliferation and other tumor-promoting activities. In this respect, the authors tried to define the correlation of soft tissue lipoma tumor cell and specific 2 immunohistologic markers, vascular endothelial growth factor (VEGF) and EGFR.The study population included patients who diagnosed with soft tissue lipoma, 20 independent patients were selected. All specimens were stained with hematoxylin and eosin. All slides were examined by a pathologist under a microscope. ER, PR, VEGF, and EGFR expression was analyzed by immunohistochemistry. RESULT: ER, PR, and EGFR of tumor cell had significantly more negative than positive. And VEGF of tumor cell had significantly more positive than negative. There was no significantly difference between site of tumor and immunohistochemical stain. DISCUSSION AND CONCLUSION: There are only a few studies for ER and PR in soft tissue related tumors. The authors estimated that the abnormal local proliferation and accumulation of adipocyte in soft tissue lipoma is related to sex steroid hormone action, especially estrogen and progesterone. But ER and PR of tumor cell had significantly more negative than positive in this study. The authors concluded that estrogen and progesterone are not impact factor of pathogenesis of soft tissue lipoma. Vascular endothelial growth factor of tumor cell had significantly more positive than negative. Angiogenesis is an essential factor for tumor growth. The VEGF expression of soft tissue lipoma can be understood in the same context. The authors need more study to reveal an association between lipoma and EGFR, because some patients of lipoma were positive to EGFR in this study.

RESUMO

Pyogenic granuloma (PG) is a type of vascular tumor for which the growth mechanism is poorly understood. Estrogen and progesterone may influence vascular malformations by increasing neovascularization in the lesions. Pregnancy tumor is a term for PG that occurs on the gingival mucosa of pregnant women in response to local irritation or injury. The etiology and pathogenesis of this phenomenon are not fully understood. Hormonal imbalance has been hypothesized to be responsible for the development of gingival hyper-reactive inflammatory responses. Moreover, it has been shown in vitro that the female sex hormone is a potential regulator of the production of several growth factors, such as vascular endothelial growth factor (VEGF), basic fibroblast growth factor, and nerve growth factor, in various cell types. Epidermal growth factor receptor (EGFR) is also involved in a signaling cascade that influences proliferation and other tumor-promoting activities, as well as the responsiveness to chemotherapy. The aim of this study was to examine the relationship between PG pathogenesis and hormone imbalance in 21 patients. All specimens were analyzed by immunohistochemical staining with hematoxylin and eosin for the following hormones: estrogen receptor, progesterone receptor, VEGF, and EGFR. The analysis of the specimens showed that estrogen receptor and EGFR were not associated with PG, while VEGF was statistically related to PG. In addition, there was no significantly difference between sex, tumor location, or pregnancy. There are few studies about correlation between the pathogenesis of PG and sex hormones or growth factors demonstrated via immunohistochemical analysis. The results of this study indicate that estrogen and progesterone do not influence the pathogenesis of PG; however, VEGF may be associated with the pathogenesis of PG.

RESUMO

Diabetes mellitus is a common metabolic disorder. Among various complications, diabetic neuropathy and peripheral vascular disorders are closely associated with diabetic foot ulcers (DFUs). Lower extremity ulcers and amputations are ongoing problems among individuals with diabetes. There are several classification systems for DFUs; however, no prognostic system has to date been accepted as the gold standard or the optimum prediction tool for amputations. A retrospective study was designed. Demographic data and baseline laboratory data were gathered and scored or evaluated using five representative DFU classification systems. These included (i) the diabetic ulcer severity score (DUSS); (ii) University of Texas (UT) diabetic wound classification; (iii) Meggitt-Wagner classification; (iv) depth of the ulcer, extent of bacterial colonisation, phase of ulcer and association aetiology (DEPA) scoring system; and (v) site, ischaemia, neuropathy, bacterial infection and depth (SINBAD) score. Finally, a statistical analysis was performed. A total of 137 patients were included in this study. During the follow-up, DFU had healed in 51·1% of subjects and 48·9% of the individuals underwent lower extremity amputations (LEAs). In a univariable logistic regression analysis, history of previous DFU, hypertension, neuropathy, haemoglobin, C-reactive protein (CRP) and ankle-brachial index (ABI) showed a statistically significant difference between the healed group and the LEA group. Moreover, the stages, grades or overall prognostic ability of all five classifications were highly associated with the overall occurrence of LEA. On multivariable logistic regression analysis of the risk of LEA, all classifications showed a significant positive trend with an increased number of amputations. All the five classification systems exhibited high sensitivity, specificity, classification accuracy, positive predictive, negative predictive and area under the curve (AUC) values. They showed substantial accuracy and their main variables were associated with LEA occurrence. The Wagner and UT systems, although they are relatively simple to assess, were better predictors of LEA.

RESUMO

Lipoma is a common benign tumor derived from stroma that can arise in any location where fat is normally present. Giant lipoma is defined as a lesion that is >10 cm in length and weighs >1000 g. Axillary region might have been exposed to microtraumas with each movement of upper extremity, leading to the development of giant lipoma. In this report, a 56-year-old man visited us because of a soft tissue mass on the left axilla that had been noticed 5 years before. We removed the tumor from the patient under general anesthesia. A lipoma measuring 21 cm × 12 cm in size was removed, and the weight of the mass was 455 g.
