I ntracranial dermoid cystic tumors account for <1% of all intracranial masses. Dermoids are nonneoplastic, congenital ectodermal inclusion cysts that contain varying amounts of ectoderm derivatives to include apocrine, sweat, and sebaceous cysts as well as hair follicles, squamous epithelium, and possibly teeth. Th ey are not to be confused with an epidermoid cyst, which contains only squamous...

DERMOID cysts are most commonly found at the upper and outer angle of the orbit (Wolff, 1951). They are smooth, round or hour-glass shaped, and vary in size from a pea to a large orange. They may be differentiated from a cephalocele by their tenseness and incompressibility and the absence of cerebral symptoms (Duke-Elder, 1964). They contain secretions of the sweat and sebaceous glands and cast...

We present a case of testicular dermoid cyst that was treated with transinguinal excision of the testicular cyst with preservation of the healthy testicular parenchyma. We have reviewed the literature for clinical features and therapeutic approach in benign cystic tumors in the pre-pubertal testis.

A German Shepherd Dog presented with recurrent intermandibular and intralingual swelling. Cytological and microbiological findings on fluid aspirated from the mass were consistent with an infected cyst lined by epithelium. The sinus was explored and an epithelium-lined cystic structure was extirpated from the frenulum and body of the tongue. This structure was diagnosed histologically as a derm...
