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.

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...

To the Editor: Epidermoid cyst, was first described by an artist in a French medical school in 1807, [1] is a kind of congenital disease characterized by a stratified epithelial capsule and laminated keratin debris contents. It accounts for approximately 1% of all intracranial tumors and commonly locates in the cerebellopontine angle, parasellar region, and the fourth ventricle. Cerebrospinal f...

Epidermoid cysts are rare congenital tumors of the central nervous system (CNS), histologically benign and slowgrowing lesions. Their frequency among primitive intracranial tumors is about 1% and they account for 40% of all intracranial epidermoid of the cerebellopontine angle (CPA); there they constitute the third most frequent neoplasm (5%), after acoustic neuromas and meningiomas. We report ...

abstract urinary retention, a rare childhood problem which is most commonly caused by urinary tract infection. however, neurological neoplasm must also be considered in differential diagnosis. we report here a 3 year old girlthat was referred to the pediatrics department of kashan university of medical sciences (kaums) with a history of urinary retention for 10 days. by insertion of a foley cat...
