Introduction:Pembrolizumab, a monoclonal antibody targeting programmed cell death-1 (PD-1), is approved as a therapy for unresectable or metastatic melanoma. Immunotherapy-associated pneumonitis is an uncommon event.Patient concerns:A 73-year-old man was admitted to our hospital with a history of melanoma on the left side of the face (resected in December 2012) and metastasis to the left lung upper lobe (resected in November 2016). Recurrence of metastasis to the bilateral lungs and left pleura was detected in April 2018. A complete response was achieved following treatment with pembrolizumab, with lower limb rashes the only adverse events occurring during therapy. The patient was readmitted in March 2019 with a productive cough, shortness of breath, and mild fever, and sputum culture identified Escherichia coli.Diagnosis:A diagnosis of pneumonia was made, and although cough and shortness of breath responded to ceftazidime and levofloxacin, but fever and poor appetite persisted. Computed tomography showed no improvement in the bilateral lower lobe lesions. Prednisone was initiated based on a clinical diagnosis of immunotherapy-related pneumonitis. The response to prednisone confirmed the diagnosis.Interventions:The patient first received ceftazidime and levofloxacin, but the symptoms persisted. Prednisone was initiated based on a clinical diagnosis of immunotherapy-related pneumonitis.Outcome:Complete resolution of the bilateral lung lesions occurred after 45 days of prednisone therapy.Conclusion:This case report highlights that both pneumonitis and bacterial pneumonia can occur as complications of anti-PD-1 immunotherapy. 相似文献

Organizing pneumonia (OP) is a nonspecific response to various forms of lung injury and has been reported in association with several infectious agents. However, little is known about the relationship between OP and chronic pulmonary aspergillosis, and the mechanism of this linkage has not been elucidated. Here, we present a case of chronic pulmonary aspergillosis that led to the development of OP, which was successfully treated with corticosteroid and surgical intervention. In a review of the literature, we aim to highlight the possible relationship between OP and chronic pulmonary aspergillosis. 相似文献

Rationale:Primary vaginal malignant melanoma is a sporadic and very aggressive tumor that is treated through surgery or radiotherapy combined with chemotherapy. Since most cases are diagnosed at an advanced stage, the operation range is extensive, the quality of life is poor, and the prognosis is gloomy.Patient concerns:A 58-year-old woman presented irregular water-like leukorrhea for 1 month after 6 years of menopause. Positron emission tomography-computed tomography revealed a 3.1 × 2.6 × 3.2 mass on the middle and lower part of the right vaginal wall. A gynecological examination revealed a 2 to 3 cm exophytic black mass in the lower-right part of the vaginal orifice. This mass was 2 cm from the urethral orifice. Furthermore, the mucosa of the anterior inferior vaginal wall had blackened and thickened, and there were some scattered black dots at the medial labia minora.Diagnosis:Due to the patient''s symptoms with radiographic findings, the postmenopausal woman was diagnosed with primary vaginal malignant melanoma.Interventions:Surgery was done to remove the mass. The patient also underwent inguinal lymph node dissection, received immunotherapy, and was treated with nivolumab.Outcomes:After a 6-month follow-up period, the patient underwent a routine gynecological examination with negative radiological results. Moreover, no local recurrence or distant metastases were found.Lessons:This patient showed a good response to immunotherapy. With this treatment method, the prognosis is better for advanced-stage women, especially those who cannot endure the surgery. Local lesion resection and inguinal lymph node dissection combined with immunotherapy are recommended. The case reported here may help treat similar clinical cases. 相似文献

Pulmonary artery sling (PAS) and tracheal agenesis (TA) are rare diseases, and most cases of PAS are associated with tracheal bronchial malformations. However, PAS associated with TA is yet to be reported. We report a case of PAS with TA diagnosed prenatally. Due to the extremely low incidence, physicians do not have sufficient understanding of these diseases and it is challenging to diagnose these diseases by prenatal ultrasound, with high rates of misdiagnosis. Prenatal examination of the pulmonary artery branches, trachea, and esophagus is useful; therefore, improving the accuracy of prenatal diagnosis will help in perinatal management and counseling. 相似文献

Rationale:Most gastrointestinal melanomas are metastatic from an oculocutaneous primary lesion; however, primary gastrointestinal melanomas have been found in all levels of the gastrointestinal tract. We present the case of Primary malignant melanoma of the esophagus and discuss the diagnostic methods, differentiation from metastatic lesions and treatment options.Patient concerns:A 78-year-old male patient presented with fresh blood vomiting and tarry stools for 1 day.Diagnoses:Esophagogastroduodenoscopy of this patient revealed a tumor ∼4 cm in size at the cardia side of the esophagogastric junction with dark-red and gray pigmentation. Immunohistochemical stains of the biopsy specimens were positive for S-100 and HMB-45, which are specific markers of melanoma.Interventions:Laparotomy with proximal gastrectomy was performed by the surgeon. Histological examination of the surgical specimen revealed the tumor arose from the distal esophagus with invasion of the proximal stomach. Primary malignant melanoma of the esophagus was diagnosed after a full skin and ophthalmic examination and positron emission tomography, which revealed no lesions elsewhere in the body.Outcomes:No tumor recurrence was noted at the 1-year follow-up.Lessons:Primary malignant melanoma of the esophagus is an extremely rare but highly aggressive tumor. The special pattern of pigmentation should be recognized while performing endoscopy. Early detection and radical resection of the tumor are critical to ensure favorable outcomes. 相似文献

Cardiac malignant mesenchymoma is an extremely rare malignancy with poor prognosis. We report a patient presenting with a history and clinical findings typical of mitral stenosis. Transthoracic echocardiography showed a mass on the thickened posterior mitral leaflet. Transoesophageal echocardiography revealed two tumoural masses: one on the atrial side of the posterior mitral leaflet causing mitral obstruction, the other arising in the region of the right lower pulmonary vein orifice and obstructing inflow through this vein. 相似文献

Noncompaction of the ventricular myocardium (NVM), also known as spongy myocardium, is a rare type of cardiomyopathy that has a serious impact on fetuses, children, and adults. NVM mainly affects the left ventricle, as isolated right ventricular noncompaction (IRVNC) is rare. Pulmonary artery sling (PAS) is a rare condition in which the left pulmonary artery anomalously originates from a normal positioned right pulmonary artery, and only a few studies have reported PAS in fetuses. Fetal IRVNC complicated with PAS has not been reported yet. Here, we report a case of IRVNC complicated with PAS that was diagnosed prenatally at 30 weeks gestation and confirmed by postpartum anatomy and pathology. 相似文献

Rationale:Several hereditary myopathies that can predispose to malignant hyperthermia (MH) are reported. However, the risk of MH in myotonic dystrophy type I (DM1) has been suggested equal to general population, although the evidence is limited to only a few case reports.Patient concerns:We encountered a rare case of MH during anesthesia induction with sevoflurane in a male adolescent with previously undiagnosed DM1.Diagnoses:After the event, genetic testing revealed the presence of a previously unknown heterozygous missense mutation in ryanodine receptor 1 (RYR1) associated with MH (c.6898T > C; p.ser2300Pro). Concomitantly, the patient was diagnosed with DM1 with abnormal cytosine-thymine-guanine triplet expansion in the DMPK gene.Interventions:Dantrolene was administered to treat the hypermetabolic manifestations in 20 minutes after the identification of MH.Outcomes:The patient was successfully treated and discharged without any complications. Laboratory abnormalities were recovered to baseline at postoperative 4 days.Lessons:The authors suggest that possible MH susceptibility in DM1 patients may be refocused. Genetic testing can be a screening tool for MH susceptibility in these population, prior to receiving general anesthesia. 相似文献

Nocardia infection is rare but potentially fatal. Therapy of Nocardia infection remains difficult. Linezolid, a novel oxazolidinone antibiotic, has proven to be effective, but clinical data are limited. Here we describe a case of a 45-year-old man with pulmonary N. farcinica infection following a liver transplantation. The initial therapy was trimethoprim-sulfamethoxazole, which showed no effect. According to susceptibility test, linezolid was administered with clearly improving the patient's condition. The treatment was stopped for anemia as drug related adverse event, and the therapy lasted for as long as 5 months. At the end of treatment clinical cure was confirmed and anemia reversed after discontinuation of linezolid. We also analyzed the clinical data of previously published reports by literature review, focusing on the efficacy and safety of linezolid treatment for Nocardia infection. 相似文献

During the past decade, Mycobacterium chelonae has been recognized with increasing frequency as a pulmonary pathogen. A review of previously reported cases reveals that most patients with pulmonary infections due to M. chelonae are nonimmunosuppressed but have underlying chronic lung disease. The infection is notably absent among blacks. M. chelonae organisms are characterized by a high degree of in vitro resistance to antituberculous drugs, and attempts at eradicating the organism through chemotherapy have been largely unsuccessful. The case of a 63-year-old previously healthy woman with progressive bilateral pulmonary disease due to M. chelonae is reported; she was treated successfully with a combination of cefoxitin and orally administered ciprofloxacin. Our experience supports the use of quinolones in combination with other active agents for the treatment of pulmonary infection due to M. chelonae. 相似文献

Rationale:Malignant phyllodes tumors with osteosarcomatous transformation are exceedingly rare. The clinical manifestations are similar to those associated with benign giant calcification, resulting in nonspecific and complex clinical symptoms.Patient concerns:A 59-year-old woman presented with a firm, painless, movable, 5.0 × 4.0 cm lump in the lower inner quadrant of the left breast that she had detected 1 month prior.Diagnoses:Breast osteosarcoma originating from a malignant phyllodes tumor was confirmed by histopathologic and immunohistochemical evaluation.Interventions:The patient underwent a wide local excision.Outcomes:The patient recovered uneventfully and was discharged after the operation. The 6-month postoperative follow-up assessment revealed no evidence of recurrence.Lessons:Diagnosing malignant phyllodes tumors with osteosarcomatous transformation requires a high level of suspicion and awareness by both surgeons and pathologists. They should be aware of the extent of such disease, which might be mistaken as benign giant calcification. Medical history and imaging findings are important for accurate diagnosis. Phyllodes tumor with an osteosarcomatous component is an aggressive neoplasm associated with distant metastasis. Delayed diagnosis and insufficient excision might negatively impact both treatment and survival. 相似文献

Rationale:Pancreatic schwannomas are extremely rare and are difficult to diagnose preoperatively. Over the past 50 years, only 96 cases of pancreatic schwannoma have been reported in English literature. Herein, we report a case of pancreatic schwannoma treated with enucleation.Patient concerns:A 66-year-old woman visited a local hospital due to ventosities. Ultrasonography and computed tomography revealed a pancreatic mass. She visited our hospital for further diagnosis and treatment.Diagnosis and interventions:Magnetic resonance imaging revealed a tumor in the pancreatic body, and a solid pseudopapillary tumor was considered preoperatively. During the surgery, a pancreatic mass was found growing in the pancreatic body and tail. A successful tumor enucleation was performed. The mass was 7 × 6 × 3 cm in size with a thin capsule. Pathological examination revealed that the tumor was mainly composed of spindle-shaped cells with a palisading arrangement and no atypia. Both hypercellular and hypocellular areas were visible. Immunohistochemical staining showed that protein S-100 was strongly positive. The tumor was diagnosed as a benign schwannoma originating from the pancreatic body and tail.Outcomes:Postoperatively, the patient showed good recovery. During the 24-month follow-up period, the patient remained well and free of complications.Lessons:Pancreatic schwannomas are extremely rare and difficult to diagnose using imaging examinations. Enucleation is a safe and efficacious treatment for exophytic pancreatic schwannomas. 相似文献
