CONTEXT: Dieulafoy’s disease of the bronchial tree is a very rare condition. Few cases have been reported in the literature. It can be asymptomatic or manifest with massive hemoptysis. This disease should be considered among heavy smokers when recurrent massive hemoptysis is present amid otherwise normal findings. The treatment can be arterial embolization or surgical intervention. CASE REPORT: A 16-year-old girl was admitted to the emergency department due to hemoptysis with an unknown lesion in the bronchi. She had suffered massive hemoptysis and respiratory failure one week before admission. Fiberoptic bronchoscopy revealed a lesion in the bronchus of the right lower lobe, which was suspected to be a Dieulafoy lesion. Segmentectomy of the right lower lobe and excision of the lesion was carried out. The outcome for this patient was excellent. CONCLUSION: Dieulafoy’s disease is a rare vascular anomaly and it is extremely rare in the bronchial tree. In bronchial Dieulafoy’s disease, selective embolization has been suggested as a method for cessation of bleeding. Nevertheless, standard anatomical lung resection is a safe and curative alternative.

Spontaneous bladder rupture is usually due to bladder diseases. Bladder rupture during labor or postpartum is extremely rare. Acute abdomen is the usual presentation of spontaneous bladder rupture. Patients may complain of suprapubic pain, anuria and hematuria. Some patients with intraperitoneal bladder rupture may have no abdominal pain and can pass urine without any symptoms so the diagnosis of intraperitoneal rupture may be difficult in these situations. We report a nulliparous woman with abdominal pain and distension about 20 days after normal vaginal delivery. There was intraperitoneal rupture of bladder in dome of bladder which was sealed by jejunum.

Neuroendocrine neoplasm (NEN) of the larynx consists of 0.6% of laryngeal cancer and is the second most common type after squamous cell carcinoma (SCC). Laryngeal NEN rarely secret calcitonin and should be differentiated from medullary thyroid carcinoma. It makes a diagnostic and therapeutic challenge. We describe a case of a laryngeal NEN with calcitonin hypersecretion. A 59‐year‐old man presented to our clinic with recurrent cough, dysphonia, hoarseness, cervical mass, and significant weight loss. Diagnostic workup showed a supraglottic mass. Biopsy of the lesion revealed large‐cell neuroendocrine neoplasm. Further diagnostic workup showed elevated serum calcitonin level. The patient underwent total laryngectomy, thyroidectomy, and modified radical neck dissection. During his follow‐up, new subcutaneous nodules appeared that were biopsy‐proven metastases. Then adjuvant chemoradiotherapy was performed. Laryngeal NEN with hypersecretion of calcitonin is a rare entity. In patients with elevated serum calcitonin levels and head and neck tumors, it should be considered a differential diagnosis of medullary thyroid carcinoma. As the management and prognosis of these two neoplasms are entirely different.

Knowledge of aberrant renal vasculature is critical for preoperative planning of either open or minimally invasive renal surgery. A precaval right renal artery is a rare anatomical variant in which the artery passes anterior to the inferior vena cava(IVC), as opposed to coursing posteriorly. When encountered, this artery is mostly accessory and thus accompanied by renal vessels in orthotopic position.Here, we describe an unusual instance of a solitary, main precaval right renal artery. It can be diagnosed preoperatively by a cross-sectional imaging study.

Background: In March 2020, the World Health Organization (WHO) declared the novel COVID-19 infection a pandemic. Among high-risk patients infected by the virus, upper gastrointestinal cancer patients, similar to other immunosuppressed patients, are vulnerable to developing more severe infections. Most of the routine activities of medical centers, especially cancer surgery centers worldwide, are affected by the epidemic. Thus, some modifications are needed to adjust international protocols to deal with upper gastrointestinal cancers worldwide. Methods: The headings of upper gastrointestinal cancer management protocols have been discussed among the university-affiliated professors in different disciplines involved in upper gastrointestinal cancer management at the first peak of COVID-19 in Iran in March 2020. The discussions were done through an interactive application (WhatsApp and Telegram) in which participants considered the headlines and the latest news about COVID-19. Under each heading, we provide the consensus of all members in the related disciplines. Recommendations and Conclusion: All members agreed to choose the most effective and the least hazardous recommendations regarding patients and medical staff in each specialty. The members understand that some recommendations may intervene with the standard best practice and reduce the best outcome that the patient can gain with standard management. Therefore, these recommendations are legitimate simply at the peak of the epidemic COVID-19 situation or the surge of any other unknown situations that we may encounter in the future. According to the consensus of cancer surgery professors in several cancer surgery centers, patients with T1 and T2 gastric cancer without lymph node involvement should undergo upfront surgery. Patients with T3 or more and/or lymph node involvement will have total neoadjuvant chemotherapy, and the surgery should be delayed until the end of the COVID-19 peak. Diagnostic laparoscopy should be postponed during the peak of COVID-19 till after the completion of neoadjuvant chemotherapy. Upfront surgery should be performed in patients with esophageal cancer (adenocarcinoma or SCC) with T1 or T2 and without lymph node involvement. In patients with T3 or more and/or lymph node involvement, neoadjuvant chemoradiotherapy (CRT) is recommended. Endoscopic stent placement is preferred for patients who complete neoadjuvant CRT during the peak of COVID 19 and have severe dysphagia. A PET-CT scan will be performed in patients without dysphagia. In the status of high uptake, surgery is reasonable, but in low uptake status without any dysphagia, only conservation is our suggestion.

Candida osteomyelitis is a rare disorder; however, its incidence has drastically risen especially during the last 3 decades. Diagnosis is usually delayed due to nonspecific symptoms. Thus, its management would not be performed at the proper time, which leads to increased morbidity. The optimal management of candida osteomyelitis is not clearly defined but most recommendations advise prolonged antifungal therapy in addition to surgery. Here, we report candida osteomyelitis in a patient with a history of pancreatic adenocarcinoma that presented with prolonged FUO as her first presentation. Fortunately, her symptoms completely resolved after prolonged medical therapy despite delay diagnosis due to her unusual presentation. To the best of our knowledge, it is the first report of candida vertebra osteomyelitis that presents with prolonged FUO as the first presentation.

Primary oral mucosal melanoma is a rare disease. Etiopathogenesis of oral mucosal melanoma (OMM) is inadequately understood. The prognosis of OMM is very poor . Due to its low incidence and late recognition, the optimal treatment modality is not well established. Surgery with free margins is the mainstay of treatment.
