Retroperitoneal sarcoma is relatively uncommon. We share our experience in encountering retroperitoneal sarcoma with vascular and urethral adhesion in a 46-year-old woman. Given the rarity of these tumors, evaluation and management should ideally be performed in a center equipped with multidisciplinary expertise in treating sarcomas.

Methemoglobinemia is a rare but fatal disorder of the oxygen-carrying capacity of hemoglobin. Here is a case representing high-dose Sulfamethoxazole/ Trimethoprim ( SMX/TMP ) induced Methemoglobinemia in a boy treated for Ventilator-associated pneumonia (VAP), which was resolved successfully after administration of methylene blue and discontinuation of SMX/TMP

Considerable calcification and stenosis frequently occur in the radial artery (RA) in diabetic nephropathy. PTA was performed successfully using balloon to expand and restrictively tear the longitudinal axis of the RA. Serendipity,the method indicates it may be a useful measure of promoting maturation of AVF in diabetic nephropathy

Odontomas are common occurrences in the oral cavity and can be classified as complex or compound. Erupted peripheral compound odontomas are rare and are present in the extra-osseous soft tissues. In this case the odontoma led to the impaction of permanent teeth for which removal of the lesion was advised.

Spontaneous isolated superior mesenteric artery dissection (SISMAD) is a rare and potentially fatal cause diagnosis presenting with acute abdominal; however, because of its rarity, the pathogenic factors of SISMAD remain unknown and no clear cause has been found. Moreover, there is a lack of evidence-based treatment guidelines.

Acupuncture is often used for acute and chronic low back pain; however, its efficacy is controversial, primarily for acute low back pain (ALBP). Our case study suggests that single acupuncture could relieve ALBP within a short time without any adverse events.

A man diagnosed as TAFRO syndrome was successfully responded to a novel immunosuppressive regimen containing methylprednisolone and mycophenolate mofetil. Blood cells firstly recovered, followed by the general situation and complete recover 1 month later, highlighting the danger of TAFRO syndrome and the importance of immunosuppressive agents in reversing pathological course

A 15 year child is presented with transfusion dependent chronic anemia. The clinical and laboratory features suggested a chronic nonspherocytic hemolytic anemia (CNSHA) with bone marrow suggestive of congenital dyserythropoietic anemia (CDA). DNA studies revealed the underlying novel mutation in the PKLR gene responsible for pyruvate kinase deficiency.

Rendu Osler's disease is a genetic disease characterized by mucocutaneous and visceral telangiectasias. Rendu Osler's disease was discovered during hypoxemia during an outbreak of SARS-Cov2.This was a 36-year-old woman with exertional dyspnea and severe hypoxemia revealing pulmonary arteriovenous malformations on chest CT scan.

Immunoglobulin G4-related disease is an inflammatory condition with unique clinical, serological, and pathological features. Here, we report a diagnostic challenging clinical case. Histopathology was used to diagnose his Ig4RD. This unique inature reinforces the fact that it is crucial to consider the diagnosis of IgG4-RD in those presenting with pachymeningiti

Varices are a common cause of gastrointestinal bleed, but a small percentage of these bleeds are due to ectopic varices. This case presents bleeding ectopic varices in the third part of the duodenum with portal hypertension secondary to chronic superior mesenteric vein thrombosis that developed after hemorrhagic pancreatitis.

In the COVID-19 pandemic, the overlap of clinical features between the other viral infections, make a reliable diagnosis difficult in the initial stage of illness. We describe the first confirmed case of CCHF in Tehran province during this year, who first misdiagnosed as COVID-19 infection.

Here we present two cases in older adult patients with highly destructive changes in ankle joints (Larsen Grade IV) and who underwent retrograde intramedullary nail fixation with fins. In both patients, bony union was achieved, full weight-bearing was attained 3 months after surgery and good functional outcome was acquired.

A 56-year-old female with pulmonary Mycobacterium avium complex disease started to inhale of liposomal amikacin. One month later, she developed hoarseness and was diagnosed with laryngitis. The laryngitis healed immediately after discontinuing the treatment, and no recurrence occurred even after resuming intermittent inhalation.

This clinical image presents an unusual report of simultaneous laparoscopic resection of a hydrocele of the canal of Nuck and an ovarian tumor. Laparoscopic treatment with a proper approach is a useful technique in some cases.

Lingual thyroglossal duct cysts can be a rare cause of feeding difficulties in infants. Here, we describe a case of an undiagnosed lingual thyroglossal duct cyst in an infant with vomiting and feeding difficulty, who underwent surgery for Hirschsprung's disease and had an unexpected difficult airway during anesthesia induction.

The sacroiliac joint is rarely affected by tuberculosis. Only few cases have been reported. Consequently, the diagnosis is often delayed. This case report highlights the importance of continued awareness for early detection and treatment of a tuberculous sacroiliac joint infection.

Paclitaxel-coated balloons have demonstrated improved efficacy compared with uncoated percutaneous transluminal angioplasty for femoropopliteal artery disease. While applying a long balloon, twisting of the balloon can be occurred. We reported two cases with twisting of the Ranger drug-coated balloon for treating superficial femoral artery.
