Subureteral endoscopic injection is a safe and effective treatment for vesicoureteral reflux (VUR). Dextranomer/hyaluronic acid (Dx/HA) is the most commonly used bulking agent for the treatment of VUR. We report a confusing radiographic finding of calcified Dx/HA injection initially simulates distal ureteral stone in a female patient who has intermittent lumbar pain. Calcification of Dx/HA implants may mimic distal ureteral calculi; therefore, urologists should be aware of the potentially confusing radiographic images...

BACKGROUND: Extraosseous Ewing Sarcoma (EES) arising from peripheral nerves is extremely rare with only 11 cases, mentioned in the literature. It poses a diagnostic challenge to the clinicians due to its nonspecific presentation and rare occurrence. CASE DESCRIPTION: A 56-year-old woman came with a history of low back pain and intractable right leg pain. Physical examination revealed the normal motor power of both lower limbs with decreased sensation along the lateral aspect of the foot with decreased ankle reflex...

Purpose . Treponema pallidum is known as the "great masquerader" for its many presentations and ocular findings in patients who are infected and develop secondary and tertiary stage of syphilis. Syphilitic ocular manifestations include uveitis, chorioretinitis, retinitis, vasculitis, vitritis, and panuveitis all with or without decreased visual acuity. Human immunodeficiency virus (HIV) is known to expedite the progression of syphilis when patients are coinfected, thus compounding the potential ophthalmic presentations...

Primary neuroendocrine tumours of the cervix are extremely rare, with an incidence of only 0.5-1%; as such, these entities can present a clinical and diagnostic challenge. Small-cell neuroendocrine carcinomas of the cervix are highly aggressive tumours that have a tendency to metastasise. We report a 44-year-old woman who presented to the Gynaecology Clinic of the Employees State Insurance Corporation Medical College & Hospital, Faridabad, India, in 2016 with menorrhagia . Based on a clinical examination, she was provisionally diagnosed with a cervical fibroid...

Aortic dissection usually presents as an acute emergency and less commonly presents as chronic dissection. Two-dimensional and transoesophageal echocardiographic features of aortic dissection generally show dissection flap, dilated aorta and aortic regurgitation. We report a very unusual and extremely rare case of a 40-year-old female patient with chronic aortic dissection presenting as functional double aortic valve.

A 58-year-old man, a known diabetic and hypertensive for 5 years was presented to us with a drop in reading vision in both eyes of 2 months duration. His best-corrected visual acuity was 6/24, N36 in both eyes. Fundus findings revealed moderate non-proliferative diabetic retinopathy with bilateral diffuse macular oedema. When conventional therapy with intravitreal ranibizumab did not alter the clinical picture, we looked into the differential diagnosis of bilateral persistent macular detachments and investigated further...

Extranodal lymphomas involve adrenal glands as a mass lesion in 3% to 5% of cases as identified by imaging studies. Definitive diagnosis of the neoplasm is provided by morphological and immunophenotypical evaluation on limited tissue obtained by fine needle aspiration or core biopsy. We report a diagnostically challenging case that presented as masses involving adrenal gland and lung in the setting of a concurrent primary renal cell carcinoma. PAX8, a frequently used marker for renal cell carcinoma, was immunoreactive in the neoplastic cells of the adrenal mass, and thus highly suggestive for metastatic renal cell carcinoma...

Langerhans cell histiocytosis (LCH) is a rare proliferative disorder, which commonly arises in the bone and may involve other systems. To date, the diagnosis of temporal bone LCH remains a challenge as it may masquerade as a common ear infection. We report a case of a child who presented to us with persistent bilateral ear discharge for four months and was not responding to treatment. Her condition subsequently worsened, with clinical features and radiological findings suggestive of mastoid cellulitis. Nevertheless, further histopathology study revealed LCH...

Osteomyelitis is an infection that is challenging to manage due to the poor vascularization of bone that favors the proliferation of microorganisms. We report a case of osteomyelitis occurring in endodontically treated teeth in the maxillary palatal region. Clinically and radiographically, it was initially diagnosed as osteomyelitis and was treated accordingly with antibiotics for 1 year with no reported healing. Later, biopsy was done and the findings were consistent with that of chronic osteomyelitis in association with infection by Actinomyces organisms...

The primary hypertrophic osteoarthropathy (PHOA) (pachydermoperiostosis) is a rare genetic/hereditary disease characterized by skin changes (pachydermia), clubbing of fingers and periosteal thickening (periostitis) with sub-periosteal new bone formation. Here we describe a case of an adolescent male who presented with clubbing and polyarthralgia. On evaluation with scintigraphy and SPECT-CT, he was diagnosed to have incomplete form of PHOA(skeletal manifestations without skin changes). The identification of incomplete form of primary hypertrophic osteoarthropathy which can be easily misdiagnosed as rheumatoid arthritis is discussed here...

Here we reported a case of bronchial adenoid cystic carcinoma from Peking University Third Hospital. A 40-year-old female presented with dry cough for 1 year and nocturnal paroxysmal attacks of wheezing for 4 months. She was a non-smoker, and did not have past histories of asthma or allergy. On physical examination, no stridor, wheezing and cyanosis were present and the general appearance was good. The results of the laboratory analysis, including blood eosinophils count, immunoglobulin E level and chest X-ray were normal...

Pure squamous cell carcinoma (SCC) of the ovary is rare. SCC can arise in a mature teratoma (MT), ovarian endometriosis or in a Brenner tumor. SCC is the most common malignant transformation arising in MT and comprises 80% of all cases. Such neoplastic transformations are extremely difficult either to predict or detect early. The mechanism of malignant transformation has not been completely understood. Due to the rarity and the aggressive course, diagnosis and treatment constitute a big challenge. We report a case of SCC arising in MT presenting with a huge abdominopelvic mass and abundant peritoneal collections clinically masquerading as abdominal tuberculosis...

Purpose: To explore the impact of ocular surface insults on the immunomodulatory capacity and phenotype of corneal epithelial cells (CECs) with a focus on epithelial-mesenchymal transition (EMT). Methods: Corneas were harvested from mice 6 days following scratch injury, ragweed pollen-induced allergy, or herpes simplex virus type 1 (HSV-1) infection and compared to healthy tissue controls. Corneas were enzymatically digested and CECs phenotypically characterized using flow cytometry...

Motion is generally assumed to "break" camouflage. However, although camouflage cannot conceal a group of moving animals, it may impair a predator's ability to single one out for attack, even if that discrimination is not based on a color difference. Here, we use a computer-based task in which humans had to detect the odd one out among moving objects, with "oddity" based on shape. All objects were either patterned or plain, and either matched the background or not. We show that there are advantages of matching both group-mates and the background...

We describe the case of a 67-year-old man presenting with ventricular tachycardia (VT) and systolic heart failure secondary to a left adrenal phaeochromocytoma. After treatment with amiodarone, the patient's VT resolved. However, his course was complicated by femoral deep venous thrombosis secondary to an incidentally discovered dedifferentiated liposarcoma of the thigh, for which he was prescribed a course of enoxaparin. The patient was discharged with plans for adrenalectomy following achievement of sufficient preoperative heart rate and blood pressure control with alpha-adrenergic receptor blockade, but re-presented to an outside facility in haemorrhagic shock, where he ultimately expired...

The porphyrias are a group of rare metabolic disorders that result from defects in heme biosynthesis. Erythropoietic protoporphyria (EPP) is the most common inherited porphyria in children and is diagnosed in most individuals after the onset of cutaneous manifestations. Hepatobiliary disease affects the minority of individuals with EPP and usually manifests in patients with an established diagnosis of EPP. We report on a classic but rare case of EPP that masqueraded as cholestasis. An 8-year-old boy was referred to the Hepatology Clinic after an abrupt onset of jaundice with a longstanding history of dermatitis...
