A 4-year-old dog was presented for acute, progressive tetraparesis and cervical hyperesthesia. Symmetrical tubular structures coursing along the lateroventral aspects of the spinal cord at the fourth and fifth cervical vertebrae were identified in magnetic resonance images. At necropsy, vertebral arteries and their spinal branches were severely ectatic bilaterally, and the cervical spinal cord was compressed. Histologically, the ectatic branches of the vertebral and ventral spinal arteries were surrounded by fibrosis with scant mononuclear cell infiltrates and hemorrhage. Spinal branches of th

Despite advances with new generation stents, there remains some atypical coronary anatomy where optimal stenting continues to be a challenge; such as stent sizing in large, ectatic or aneurysmal vessels; tapered vessels; and in vasoconstricted arteries such as in ST-segment elevation myocardial infarction or chronic total occlusions. Balloon-expandable stents are tubular and cannot easily accommodate vessel diameter variations; thrombotic vessels increase the risk of distal embolisation and no-reflow; positive remodelling and vasodilation often result in subsequent malapposition; and patients

Abstract We report the case of a 43-year-old quadriplegic woman with bilateral vulvar enlargement. The clinical impression was labial hypertrophy, but the microscopic features mimicked aggressive angiomyxoma because of the location, hypocellular proliferation of fibroblastic cells in an edematous-myxoid stroma, and vessels with perivascular collagen deposition, which simulated the thick-walled vessels of aggressive angiomyxoma. Since the lesion lacked true thick-walled vessels and contained ectatic tortuous lymphatics, the pathologic interpretation was lymphedema. This vulvar lesion should be

Introduction: Coronary artery ectasia (CAE) refers to a 1.5 fold increase in coronary artery diameter compared to the normal segment. Although the underlying pathophysiological mechanism is not fully elucidated, coronary atherosclerosis is thought to play a role in more than half of the cases. Triglyceride glucose (TyG) index is an indicator of insulin resistance. In the present study, aimed to evaluated TyG index values in CAE cases and find if a predictive value of TyG index existed.

Acquired lymphangiectasia is an unique entity encountered by an urologist which is marked by occlusion of lymphatics associated with abnormal permanent dilation of cutaneous lymphatics. There is presence of thin-walled ectatic vessels in the superficial and mid dermis, which develops later in life. Trauma, infection, radiation or surgery are important causes of this rare aetiology. Diagnosis is always demanding, as it closely resembles many benign aetiology. Meticulous decision-making and appropriate treatment should be chosen for the management.

Scalp arteriovenous malformations (AVMs), commonly known as cirsoid aneurysms, are complex collections of arteries and veins that communicate directly. It has been postulated that AVMs occur both through the activation of inactive fistulous lesions and through the formation of new fistulous vascular channels through the canalization of injured vessels. Depending on their size and complexity, a variety of strategies can be used to treat them.

Pleomorphic hyalinizing angiectatictumor (PHAT), a rare low-grade non-metastasizing tumor, was first reported in 1996[1]. It affects patients with a mean age of 54.5 years and no predilection for gender[2], and has a preference for the subcutaneous soft tissue in the lower extremity. The main histology features are clusters of hyalinized ectatic blood vessels and scattered pleomorphic cells or spindle cells with nuclear pseudoinclusions. The clinical behavior is characterized by local recurrence in 30-50%, and no cases have been known to metastasize. A wide intralesional excision and long-term

Introduction: Primary lymphedema is usually caused by intrinsic disruption or genetic damage to the lymphatics but may also be the result of age-related deterioration of the lymphatics. The aims of this study were to determine the characteristics of age-related lymphedema and to assess the effectiveness of lymphaticovenous anastomosis (LVA) in its treatment. Methods: Eighty-six patients with primary lymphedema affecting 150 lower limbs were divided into three groups according to whether the age of onset was younger than 35 years, 35–64 years, or 65 years or older.

Object Hemifacial spasm (HFS) is caused by arterial or venous compression of cranial nerve VII at its root exit zone. Traditionally, microvascular decompression of the facial nerve has been an effective treatment for posterior inferior and anterior inferior cerebellar artery as well as venous compression. The traditional technique involves Teflon felt or another construct to cushion the offending vessel from the facial nerve, or cautery and division of the offending vein. However, using this technique for severe vertebral artery (VA) compression can be ineffective and fraught with complication

Abstract Dermoscopy of mucosa is known as mucoscopy. Mucoscopy can aid in delineating minute aspects of mucosal lesions and will help to differentiate similar-looking lesions. The aim of this study is to describe mucoscopic features and correlate them with histopathology in various genital mucosal diseases. The study was conducted at a tertiary care centre between October 2020 to April 2022 after Institutional Human Ethics Committee approval.

ABSTRACT Soft tissue tumours are a heterogeneous group, including a few characterised by low malignant potential. The pleomorphic hyalinising angiectatic tumour (PHAT) is one such entity, which is slow growing and non-metastasising. The origin of this tumour is uncertain and has several clinical and morphological mimics. We present the case of a 65-year-old male, who was diagnosed with urothelial carcinoma, and he underwent radical cystectomy with an ileal conduit, after neoadjuvant chemotherapy. Pre-operative ultrasonography of the abdomen also showed a pedunculated soft-tissue lesion in the
