BACKGROUND AND PURPOSE The purpose of this study was to describe the CT and MR imaging findings of nodular fasciitis occurring in the head and neck region. METHODS CT (n = 6) and MR (n = 4) images obtained from 7 patients (3 men and 4 women; mean age, 19.4 years; age range, 1-48 years) with surgically confirmed nodular fasciitis in the head and neck were retrospectively reviewed. All patients...

A male cynomolgus monkey (Macaca fascicularis) of 5 years and 11 months of age from the vehicle control group of a 4-week repeated oral dose toxicity study had a spontaneously occurring mass lesion directly attached to the proximal part of the left trigeminal nerve. Histologically, the mass was characterized by a multifocal nodular appearance. Nodular zones showed low to moderate cellularity an...

Isolated hepatic tuberculoma is localized hepatic tuberculosis (TB) without bile duct involvement, which presents as solitary or multiple nodular mass lesion of liver mimicking a neoplastic lesion in radiological evaluation. Clinical presentation and biochemical tests for liver functions show non-specific abnormality, which is not helpful for diagnosis. As the treatment, modality of isolated he...

Canalicular adenoma is a rare benign tumor of the minor salivary glands that is the most prevalent in older adults (mean age, 60 years). The upper lip is the most commonly affected site, followed by the buccal mucosa and palate. It presents as a nodular lesion without a tendency for recurrence. Here, we describe a case of canalicular adenoma presenting as a nodular, painful mass in the upper li...

BACKGROUND The peripheral hallmarks of neurofibromatosis type 1 (NF1) are Café au lait and solid nodular neurofibromas. The morphological behavior of these lesions could be susceptible to modification during pregnancy. The present case report describes a case of cystic transformation of a nodular neurofibroma, with progressive growth and mass effect in the anterior cervical region, which was su...

Abstract A 5‐year‐old, male, neutered lurcher dog was presented for investigation of a cranial abdominal mass and suspected acute pancreatitis. Advanced diagnostic imaging revealed the presence cavitated mass, multiple splenic nodules coeliac lymphadenopathy. Fluid analysis from ultrasound‐guided mass‐lesion aspiration suggestive pancreatic origin. After medical stabilisation, underwent celioto...

Nodular fasciitis is a rapidly growing mass, with high cellularity and mitotic activity, that can be both clinically and histologically misdiagnosed as a soft tissue sarcoma. Nodular fasciitis of the hand is an extremely rare condition. We report a 17-year-old male hand-ball player with nodular fasciitis in the dominant hand. The patient presented with a rapidly growing mass in his right hand a...

Introduction: Kaposi sarcoma (KS) is an HIV associated skin lesion. Kaposi sarcoma is rare in HIV negative patients and is associated with HHV-8 infection. Clinically it presents as a pink nodular mass, single or multiple which can mimic pyogenic granuloma and bacillary angiomatosis. The etiology associated with HHV-8. Treatment options modalities can vary between from electrocuatery to surgica...

Dear Editor, Pseudoepitheliomatous hyperplasia (PEH) is a benign proliferation of the conjunctival or corneal epithelium that occurs in response to inflammatory conditions [1]. There are a few reports of occurrence of PEH presenting as a limbal mass, especially in inflammatory conditions such as vernal keratoconjunctivitis (VKC) [2-4]. Here, we describe an uncommon case of PEH with vascular tor...
