epidermal cyst/edema

Two pyogenic granulomas arising from the wall of an epidermoid cyst on the midback of a 62-year-old white man are reported. Histologically, each pyogenic granuloma was a polypoid sessile nodule that showed well-vascularized granulation tissue; edema; a mixed inflammatory infiltrate; an epidermal

Reinke edema is one of the common cause of dysphonia middle-aged population, and severe thickening of vocal folds require surgical treatment. Smoking plays a major role on etiology. Vocal fold cysts are also benign lesions and vocal trauma blamed for acquired cysts. We would like to present 3 cases

Brain and skull bone epidermoid cysts were confirmed by CT and operation in 32 cases (29 in brain, 3 in skull bone and scalp). Typical CT findings of epidermoid cyst were unenhanced hypodense areas with well-defined margin, closed contact with cisterns, and without surrounding edema. CT findings of

OBJECTIVE To describe an innovative endoscopic technique to treat prepontine epidermoid cysts. These cysts are typically resected in a microsurgical fashion and can be associated with significant risks and complications. This report is the first description of an endoscopic-assisted removal of an

The follicular hybrid is composed of more than two components of pilosebaceous unit. There are several studies of hybrid cyst, combination of trichilemmal and epidermoid cyst was the most frequently reported. In this paper, we reported one case of hybrid cyst composed of bullous pilomatricoma and

BACKGROUND Epidermoid cysts that appear in the midline floor of the mouth are, usually, a result of entrapped ectodermal tissue of the first and second branchial arches, which fuse during the third and fourth weeks in utero. The incidence in the floor of the mouth of the oral cavity is rare and

OBJECTIVE Recently, we reported a tendency toward spontaneous hemorrhage in both the preoperative and postoperative periods in patients with intracranial epidermoid cyst (EC). According to our experience, this tendency for spontaneous hemorrhage was partly caused by the pathologic blood vessels

A 34-year-old man presented with recent severe headache. Neurological examination found gait disturbance and a static cerebellar syndrome. The CT scan showed a tumor located in the fourth ventricle and which presented with a density close to that of the cerebellar parenchyma, without contrast

Epidermoid cysts (ECs) are uncommon pediatric tumors that often occur in the cerebellopontine angle. Although cyst rupture is a recognized complication, the radiographic evolution of an EC following rupture and the resultant parenchymal brainstem edema have not been reported. The authors present the

The cranio-encephalic epidermoid cysts are rare tumors. These lesions are extra-axial and can occur at the infratentorial or supratentorial level. The epidermoid cysts are classically in contact with the base of the skull, and less often intraventricular; the other locations are exceptional. Because

Malignant transformation of epidermoid cysts into squamous cell carcinoma (SCC) rarely occurs. A 67-year-old man initially presented with an 8-year history of right trigeminal neuralgia. His symptoms had changed into right facial anesthesia with right-ear hearing impairment 8 months before first

A 50-year-old male presented with a recurrent epidermoid cyst with malignant transformation into squamous cell carcinoma. The patient was first hospitalized for intermittent seizures in 2000. Computed tomography (CT) showed a hypodense lesion with enhanced capsule but no peripheral edema in the

After a short review of literature, MRI assessments of four cases of epidermoid cysts (EC) are reported. EC, (characterized in computed tomography by hypo or iso-density areas non-enhanced by contrast), are characterized in MRI by: 1) an important variability of signal intensity between the

A 5-month-old boy who was diagnosed as having hydrops fetalis at 25 weeks' gestation had severe ascites of unknown origin. At the age 12 months, ultrasonography and computed tomography showed multiple cysts in the spleen that were increasing in size rapidly. Splenectomy resulted in complete
