INTRODUCTION Although rare, the malignant degeneration of epidermoid cysts is well documented. Its occurrence with leptomeningeal dissemination and malignant cells in CSF is scarce. To the best of our knowledge only four cases have been reported. CASE REPORT The authors report the case of malignant transformation of an epidermoid cyst with leptomeningeal carcinomatosis (which simulates asepti...

An elderly female patient presented to surgical outpatient clinic with complaint of gradual onset of painless submental and sublingual midline swellings for 6 months of duration. The swellings were noncompressible, nontranslucent, nonpulsatile, and nontender on palpation. Clinical diagnosis was plunging ranula or dermoid cysts. Ultrasound examination of sublingual swelling showed cystic lesion ...

Epidermoid cyst is generally regarded as congenital disease, and commonly related to other congenital spinal anomalies. However, it also develops iatrogenically. We report one rare case of epidermoid cyst that we experineced among intradural extramedullary tumors. A 21-year-old female patient was admitted to the hospital due to low back pain with radiating pain into a right lower extremity that...

Abstract Background Epidermoid cyst is a developmental lesion with 1.6–6.9% cases found in the head and neck region. Intraoral epidermoid rare finding intratonsillar even rarer, less than 0.01% incidence. Case presentation We are reporting case of 16 year old complain unilateral tonsillar enlargement since 5 months. She underwent tonsillectomy under general anesthesia, specimen was sent for his...

Kaohsiung J Med Sci October 2005 • Vol 21 • No 10 475 Epidermoid cysts can be classified as either congenital or acquired [1]. Congenital types are thought to develop from congenital inclusions of ectodermal tissue during embryologic development, whereas acquired variants are believed to originate through implantation of epithelium, by either surgical or accidental trauma into deeper mesenchyma...

The differential diagnosis of a cystic lesion in the submandibular area can be difficult. We report a case of epidermal cyst of submandibular gland which is relatively rare compared to the commoner epidermoid cyst.

We present two patients with splenic cysts. The first is a female 29-years-old who presented with upper abdominal discomfort of one-year duration. Imaging revealed a huge splenic cyst. Splenectomy was undertaken. Pathological examination revealed a lymphatic cyst. The second was an 18-years-old female who presented to the emergency department with a ruptured splenic cyst. Splenectomy was undert...

Epidermoid cysts are benign simple epithelial tumors usually appearing as hypoechoic lesions with scattered echogenic reflectors on sonography. Herein, we present a 53-year-old man with an extratesticular epidermoid cyst in the right scrotum which shows confusing sonographic findings, normal-appearing echogenicity of the lesion and atrophied testis, which lead to a diagnostic dilemma. With a va...
