ore severe preoperative pain and self-reported symptoms of instability as well as more frequent depression and lower mental health scores. The combination of disproportionate shoulder pain, comorbid back pain and mental health conditions, and inferior preoperative expectations may affect not only the patient's preoperative state but also postoperative pain control and/or postoperative outcomes. © The Author(s) 2020.BACKGROUND Although the overall incidence of tuberculosis in underdeveloped areas has increased in recent years, esophageal tuberculosis (ET) is still rare. Intestinal tuberculosis (ITB) is relatively more common, but there are few reports of ET complicated with ITB. We report a case of secondary ET complicated with ITB in a previously healthy patient. CASE SUMMARY A 27-year-old female was hospitalized for progressive dysphagia, retrosternal pain, acid regurgitation, belching, heartburn, and nausea. Upper gastrointestinal endoscopy showed a mid-esophageal ulcerative hyperplastic lesion. Endoscopic ultrasonography showed a homogeneous hypoechoic lesion, with adjacent enlarged lymph nodes. Biopsy histopathology showed inflammatory exudation, exfoliated epithelial cells and interstitial granulation tissue proliferation. Colonoscopy revealed a rat-bite ulcer in the terminal ileum and a superficial ulcer in the ascending colon, near the ileocecal region. The ileum lesion biopsy showed focal granulomas with caseous necrosis. Polymerase chain reaction for Mycobacterium tuberculosis was positive in the esophageal and ileum lesion biopsies. The T-cell spot tuberculosis test was also positive. The patient was diagnosed with secondary ET infiltrated by mediastinal lymphadenopathy and complicated with ITB, possibly from the Mycobacterium tuberculosis-infected esophageal lesion. After 2 mo of anti-tuberculosis therapy, her symptoms improved significantly, and upper gastrointestinal endoscopy showed healing ulcers. CONCLUSION When dysphagia or odynophagia occurs in patients at high-risk for tuberculosis, ET should be considered. ©The Author(s) 2020. Published by Baishideng Publishing Group Inc.

The sternum is a rare site of Hodgkin's lymphoma, which is often misdiagnosed as tuberculosis on routine histopathology. CASE SUMMARY We reported a 47-year-old female patient with chest pain in the upper sternum for 1 mo. Chest computed tomography found a mass in the upper sternum. Pathology and immunohistochemistry of the biopsy confirmed the diagnosis of typical Hodgkin's lymphoma (mixed cellularity subtype). Patient was diagnosed with primary sternal Hodgkin's lymphoma and administered 6 cycles of adriamycin, bleomycin, vinblastine, and dacarbazine chemotherapy. Patient had no tumor recurrence and progression at a follow-up visit 2 years later. CONCLUSION This study highlights the rarity of primary sternal Hodgkin's lymphoma and the challenges of its diagnosis. A PubMed and Web of Science search revealed 10 reported cases of sternal involvement in Hodgkin's lymphoma. ©The Author(s) 2020. Published by Baishideng Publishing Group Inc.

For cases of carotid artery with ipsilateral middle cerebral artery tandem embolization, the operation is more complicated and challenging. We here report a case of a tandem embolism, and the anatomy of the aortic arch was complex. Direct carotid artery incision and thrombectomy can not only prevent the escape of the carotid embolus but also save time during establishment of the thrombectomy access. CASE SUMMARY The patient was a 70-year-old man. He was admitted to hospital due to sudden inability to speak and inability to move his right limb for 3 h. Imaging confirmed a diagnosis of a tandem embolism in the left carotid artery with left M1 occlusion. Carotid artery incision thrombectomy combined with stent thrombectomy was performed. The operation was successful, and 24 h later the patient was conscious and mentally competent but had motor aphasia. His bilateral limb muscle strength level was 5, and his neurologic severity scores score was 2. CONCLUSION Carotid artery incision thrombectomy combined with stenting for carotid artery plus cerebral artery tandem embolization is clinically feasible. For patients with a complicated aortic arch and an extremely tortuous carotid artery, carotid artery incision can be chosen to establish the interventional path. ©The Author(s) 2020.

Currently, there are two kinds of inhibitors Anti-PD-1 antibodies and anti-PD-L1 antibodies. These inhibitors have shown significant implications in improving the outcomes of certain cancer types in recent years. However, along with its effectiveness, adverse events cannot be ignored. As an anti-PD-1 antibody, camrelizumab (SHR-1210) has some side effects in tumor immunotherapy. The most common adverse event is reactive capillary hemangioma. While it is widely reported to occur in the skin, gingival reactive capillary hemangioma is rarely reported. CASE SUMMARY A 54-year-old man complained of gingival overgrowth on the anterior aspect of the maxilla and mandible for more than 6 mo. He had been placed on SHR-1210 for lung cancer for 7 mo. A gingival mass extending from canine to canine was noted on the lingual surfaces of the mandible. Gingival enlargement was noted in the front teeth. A clinical diagnosis of gingival reactive capillary hemangioma and chronic periodontitis was made. The treatment involved a complex local treatment (repeated local applications of an antibiotic paste, scaling and root planning, and surgery). The excised tissue was sent for histopathological examination, which confirmed the diagnosis of capillary hemangioma. After the operation, most of the gingival enlargement was reduced. At the 2-mo follow-up, it was noted that the gingival overgrowth was immediately reduced after the replacement of the anti-PD-1 agent with an anti-PD-L1 agent. CONCLUSION As the prescription for SHR-1210 has increased considerably in recent years, the occurrence of its possible side effects, including gingival reactive capillary hemangioma, has increased. It is recommended that regular oral examinations be performed before and during the treatment of tumors with SHR-1210. ©The Author(s) 2020. Published by Baishideng Publishing Group Inc.

The characteristic clinical manifestations include multi-organ involvement, especially in the symmetrical diaphysis and metaphysis of the bilateral extremities. ECD with a unilateral talus lesion is extremely rare. Here, we report an unusual case of ECD invading the asymmetric talus and tibia without involving other organs. The patient had good outcome after surgery. CASE SUMMARY We report a case of a 67-year-old man who was referred to our outpatient department because of left ankle chronic pain for 5 years, which exacerbated after a foot sprain 6 mo previously. We discovered multiple sclerotic lesions of the tibia and talus on his previous X-ray films, which were initially missed in a local hospital.

Accordingly, there is no absolute definition of this group of tumors as yet, and our overall understanding of its morphological features, therapeutic regimen and prognosis is limited. CASE SUMMARY A 34-year-old male patient was referred to our hospital to address a 2-mo history of hematuria and progressive dysuria. Pelvic computed tomography scan revealed a 6.0 cm × 5.2 cm × 7.2 cm mass in the prostate, with bladder invasion. The patient underwent transurethral prostatectomy as upfront therapy. He refused further treatment and died of uncontrollable tumor growth 3 mo after surgery. Pathology analysis revealed the stroma to be pleomorphic, with a huge number of atypical spindle cells. Rhabdomyoblastic cells, with abundant eosinophilic cytoplasm, were detected. The spindle cells were positive for vimentin, INI1 and β-catenin, and the rhabdomyoblastic cells were positive for MyoD1, myogenin and INI1. The spindle cells and epithelial cells were sporadically positive for P53. CONCLUSION The prostatic stromal sarcoma tumor was immunoreactive for β-catenin, suggesting a role for the Wnt/β-catenin pathway in this tumor type. ©The Author(s) 2020.

However, the etiology of CEAN remains unclear, and no association with infection, trauma, or immunosuppression has been described. This case study indicated that CEAN is closely related to the patient's impaired immune status and may be induced by cyclosporine. CASE SUMMARY A 19-year-old boy with nephrotic syndrome (NS) developed large CEAN on the left foot during treatment for NS. He had repeated relapses of edema in the past 6 years and different types of immunosuppressants were administered including methylprednisolone, mycophenolate mofetil, tacrolimus and cyclosporine; the dosages of these drugs were frequently adjusted. The patient had been receiving cyclosporine and methylprednisolone for 7 mo before he developed CEAN. Cyclosporine was discontinued due to its side effects on skin. After cessation of cyclosporine and 16 mo follow-up, the nodules gradually disappeared without any other treatment for the CEAN. CONCLUSION Impaired immune status is proposed to be a risk factor for CEAN, which may be induced by cyclosporine. ©The Author(s) 2020. Published by Baishideng Publishing Group Inc.

CASE SUMMARY Here, we report a case of recurrent urothelial bladder carcinoma (UBC) in a patient who has undergone three operations, and further illuminate its diagnosis and treatment. The diagnosis of UBC was rendered according to the pathological indices. Next-generation sequencing on formalin fixed paraffin-embedded (FFPE) tissue was also performed and suggested HER2 gene amplification in the FFPE tissue. Based on HER2 gene amplification in FFPE, the patient was treated with chemotherapy in combination with trastuzumab after his third surgery. Fortunately, the patient got a clinically complete remission to trastuzumab for 34 mo. CONCLUSION There is not enough clinical evidence for incorporating trastuzumab in routine treatment of UBC.
