IMPORTANCE: Mucinous eccrine carcinoma is a rare entity that most commonly affects the head and neck. Due to its low frequency of occurrence, review of its etiology, histopathology, and treatment strategies is beneficial to all clinicians who may encounter similar appearing masses. OBSERVATION: An 84-year-old male presented with a blue mass on the left cheek. This mass started as a small bump and grew significantly over one year. His primary care physician monitored its growth and ultimately referred to an otolaryngologist...

Despite the high prevalence of tuberculosis (TB) worldwide, pancreatic TB is rare. When present, pancreatic TB is frequently associated with miliary TB, often in immunocompromised hosts. Pancreatic TB may present as a pancreatic abscess, acute or chronic pancreatitis, and cystic or solid pancreatic masses. This is a case of isolated Tubecular infection of the pancreas in an immunocompetent patient, who presented with a discrete pancreatic abscess, and was subsequently diagnosed with isolated pancreatic TB. This case suggests that clinicians should have a heightened suspicion of pancreatic TB when faced with discrete pancreatic lesions, especially in patients from areas where the infection is endemic...

Epidermoid cyst of the renal pelvis is exceptionally rare. The histogenetic mechanism has not been well characterized. Herein, we report a case of intrarenal epidermoid cyst in a 62-year-old woman who had undergone left nephrolithotomy for a staghorn calculus. She was being followed up for bilateral renal cysts when a complex mass was noted arising from the lower pole of the left kidney. Renal ultrasound showed a small left kidney with a solid vascular echogenic mass. A laparoscopic radical nephrectomy was performed...

CONTEXT: Cysts arising from the hepatobiliary tree are a group of heterogeneous lesions with regard to pathogenesis, clinical presentation, and radiological finding. They can be intrahepatic or extrahepatic, developmental, secondary to infective/inflammatory etiologies, as well as neoplastic. This study was conducted to determine the spectrum of hepatobiliary cysts in surgically intervened cases, with regard to their prevalence, histological spectrum, and clinicoradiological correlation, wherever possible...

Cystic lesions of the jaws comprise a spectrum of inflammatory, developmental and neoplastic changes that can clinically appear strikingly similar. Squamous cell metaplasia due to superinfection can further blur the histologic hallmarks of the individual lesions. In this article an overview of the most important differential diagnoses and the novelties of the latest World Health Organisation (WHO) classification on head and neck tumours released in early 2017 is provided. In contrast to the previous edition, odontogenic cysts have been re-introduced and several changes in terminology and taxonomy have been complemented...

BACKGROUND: Serous borderline tumor (SBT) of the micropapillary type (SBT-MP) became one of the major pathological SBT diagnoses in addition to typical SBT, and was also defined as "non-invasive" low-gradeserous carcinoma according to the World Health Organization (WHO) classification in 2014. In this study, we investigated the MRI appearance of SBT-MP compared to that of typical SBT in order to identify specific imaging features of SBT-MP that correspond to pathological findings. METHODS: MR images of 6 histologically proven ovarian SBT-MP in four patients and 14 typical SBT in ten patients were reviewed retrospectively...

Radiologists in any practice setting should be prepared to use thoracic magnetic resonance (MR) imaging for noncardiac and nonangiographic applications. This begins with understanding the sequence building blocks that can be used to design effective thoracic MR imaging protocols. In most instances, the sequences used in thoracic MR imaging are adapted from protocols used elsewhere in the body. Some modifications, including the addition of electrocardiographic gating or respiratory triggering, may be necessary for certain applications...

Hydatid disease is caused by Echinococcus granulosus. Hydatid cysts are commonly located in the liver and lungs. The occurrence of pancreatic hydatid cysts is very rare, even in endemic areas. Sinistral portal hypertension, which is rarely seen, occurs when a pathological process causes splenic vein occlusion. A 26-year-old male patient presented with abdominal pain. He had a history of operation for hydatid cyst of the lung 15 years ago. A left thoracotomy incision scar was observed during his physical examination...

Most pancreatic ductal adenocarcinomas (PDAs) show solid growth pattern, but ductal adenocarcinomas may demonstrate intratumoral cystic appearance or accompany peritumoral non-neoplastic cystic lesions, thus mimicking cystic pancreatic tumors on imaging studies. The histopathologic findings for PDA with cystic feature are divided into neoplastic and non-neoplastic cysts. Neoplastic cystic changes include large-duct type cysts (microcystic appearance), neoplastic mucin cysts (macrocystic appearance), colloid carcinomas (mucinous noncystic adenocarcinomas), and degenerative cystic change usually caused by hemorrhagic necrosis of tumor...

We report a case of low-grade fibromyxoid sarcoma arising within the median nerve. A 31-year-old woman presented with symptoms of carpal tunnel syndrome and an enlarging mass in her right palm over 1 year. MRI demonstrated a mass associated with the right median nerve with solid and cystic components. At surgery, the mass was located within the epineurium, could be bluntly dissected from the nerve fascicles, and was suspected to be a schwannoma. A 3.4 cm, tan-pink, glistening, smooth, homogenous mass was submitted to pathology...

AIMS: Cystic lesions derived from the synovial and ligamentous structures of the spine have varied histologic appearances. Not uncommonly, there is discrepancy between the clinico-radiologic diagnosis and histology. Therefore, we sought to characterize the histologic features of tissue submitted as "synovial cysts" of the spine. METHODS: Resected specimens of the spine labeled "synovial cysts" and "lumbar cysts" were histologically evaluated and classified based on histopathologic features...

Nabothian cysts are mucinous retention cysts formed through the accumulation of cervical mucus inside blocked cervical crypts leading to non-neoplastic mucinous cystic lesion in relation to the uterine cervix. The formation of Nabothian cysts is a common gynecological benign condition in women of reproductive age. While the presence of small-sized Nabothian cysts is usually clinically asymptomatic and requires no treatment or intervention, the diagnosis of larger Nabothian cysts can be mistaken with malignant tumors, including mucin producing carcinomas such as Adenoma malignum...

Intravascular papillary endothelial hyperplasia (IPEH) also known as Masson's hemangioma is a rare benign reactive vascular lesion of the skin and subcutaneous tissue. It is usually confined to the lumen of preexisting vessels/vascular malformations. It is characterized histologically by papillary fronds lined by proliferating endothelial cells. This lesion is often misinterpreted as soft-tissue tumors and other benign and malignant lesions. We present a case of 13-year-old female with IPEH of scalp causing bony defect because of its rarity and diagnostic challenge, it posed due to nonspecific clinical and radiological findings...

Cystic lesions of the pancreas are radiographic findings that have a very broad histologic differential. This differential spans the spectrum from benign to cancerous, and includes non-neoplastic pseudocysts, benign neoplastic cysts, pre-malignant cysts, and cystic lesions with invasive carcinoma. This chapter will highlight the challenges with diagnosis and management of patients who present with cystic neoplasms of the pancreas.
