The characteristics and incidence of dermoid cysts of the floor of the mouth are reviewed. The epidermoid cyst in the sublingual (genioglossal) position is unique because of its size and the advanced age of presentation. The use of preoperative lateral xerography was beneficial in determining the extent of the lesion and in visualizing the partial obstruction of the upper airway. An intraoral s...

52 INTRODUCTION Epithelial inclusion or epidermoid cyst (EIC) lined by well defined stratified squamous epithelium enlarges by cellular proliferation and by desquamation of keratinized debris into the cavity of the cyst (1). Histologically, it is differentiated from the dermoid cyst by the absence of dermal structures and from the benign cystic teratoma or true dermoid cyst, which is a neoplasm...

I would like to clarify a misconception about the origin and content of dermoid vs epidermoid cysts. Reference was made to this in the article "Temporoparietal Dermoid Cysts with Intracranial Extension" by Currarino and Rutledge [1]. Although these authors ' findings of dermoid cyst with sinus in an unexpected location are certainly of interest, I must differ with the statement that inclusion o...

of > 1000 U/ml in pancreas cyst fluid is considered almost pathognomonic for a mucinous cystic neoplasm. A 32−year−old woman underwent abdominal computed tomography (CT) for evaluation of right upper quadrant pain, which revealed a 10−mm pancreatic tail cyst (l" Fig. 1a, b). The sharply demarcated cyst without septation did not communicate with the pancreatic duct. Follow−up CT, 4 months later,...

Introduction: Epidermoid cysts of the neck occur less commonly than dermoid cysts of the head and neck. They are located mostly in the submental region and present as a painless slow growing swelling. The purpose of this article is to present an unusual case of submental epidermoid cyst which showed mobility and increase in the size on deglutition which is a very unusual finding. Case Report: A...

Primary intracranial squamous cell carcinomas (SCCs) are rare and mostly associated with an intracranial epidermoid or dermoid cyst. Sarcomatoid carcinoma is a rare biphasic tumor composed of both carcinomatous and sarcomatous components and has not previously been reported as a primary intracranial tumor. Here, we present a case of a 60-year-old man with a primary intracranial sarcomatoid carc...

An infected epidermoid cyst presented on CT as a primarily dense, sclerotic expansile lesion in the greater wing of the sphenoid bone. Presumably, infection was responsible for the atypical appearance.

Epidermal cyst of the skin, also referred to as epidermoid or infundibular cyst, is a common benign cystic lesion and is thought to occur from damage to the pilosebaceous units [1]. This kind of lesion is unilocular, histopathologically lined by a stratified squamous epithelium containing a granular layer, and filled with laminated and/or basket-weave keratin within the cyst, which is believed ...

Splenic cysts are rare clinical entities, reportedly occurring in only 0.5%–2.0% of the population. The first splenic cyst was reported in 1829 by Andral, and with the increasing use of diagnostic imaging, splenic cysts are now more commonly being diagnosed incidentally. We report the case of a splenic cyst in an 18-year-old man who initially presented to a remote nursing station in Labrador wi...

INTRODUCTION Epidermoid cysts are rare, slow‑growing, benign, developmental cysts, which are derived from abnormally situated ectodermal tissue. Epidermoid cysts of the floor of the mouth represent <0.01% of all oral cysts. So far, only a few cases have been reported. CASE REPORT Hereby, we present a case of a giant sublingual epidermoid cyst, which was completely asymptomatic upon presentati...
