Central angioleiomyoma of the mandible: A rare entity.

The leiomyoma is a benign smooth-muscle neoplasm commonly found in the female genital tract, gastrointestinal tract, or skin. Leiomyomas of the oral cavity are unusual. Oral leiomyomas are uncommon due to the paucity of the smooth muscle in the mouth (except in blood vessels) and thus the involvement of jaw bones is extremely rare.

Isolated angiokeratomas of the tongue: A rare entity.

Angiokeratomas consist of ectasias of dermal capillaries associated with an acanthotic and hyperkeratotic overlying epidermis. These dark red-to-purple, papular vascular anomalies can vary considerably in size, depth, and location. It is a skin disorder that rarely involves oral cavity.

Zinsser-Cole-Engmann syndrome: A rare case report with literature review.

Zinsser-Cole-Engmann syndrome, more commonly known as Dyskeratosis Congenita, is a heritable genodermatosis having an estimated incidence of 1 in 1 million people. It is important for an oral physician to be aware of this condition as oral leukoplakia occurs in this condition as part of a classic triad along with reticulate skin pigmentation and nail dystrophy. Besides these, there may be myriad multisystem involvement as well.
