Dermoid cyst with tubular bifurcation and dermal sinus.

NASAL cysts and sinuses are rare. One finds very brief descriptions of these conditions in the textbooks, but frequent reports appear in the literature, particularly in the Otolaryngology journals. Pratt found a case reported as early as 1817, and Hamilton (1960) found reference to this condition in the London Medical Gazette in 1837. Recently, a similar case was reported by Stirk-Adams (1965) from Birmingham. The case described below is the first encountered at this clinic.
