Epidermal inclusion cyst of the mandible after extraction of a third molar: case report

Epidermal inclusion cysts of the head and neck are rare. We report the case of a non-traumatic epidermal inclusion cyst in the submandibular region, with both intraosseous and extraosseous components, which communicated with the socket of a third molar extracted 12 years previously.

Peripheral calcifying epithelial odontogenic tumor – Case report

The calcifying epithelial odontogenic tumor (CEOT), Pindborg tumor is a benign, slow growing, but locally invasive neoplasm. It is known to have a common intraosseous variant and a very rare extraosseous variant. We report an unusual case of an extraosseous variant of CEOT of unusual large size and maxillary anterior location, the treatment was planned considering the clinical, radiological and histological features. Though peripheral types are less aggressive and had no recurrence, in our case regular follow up is required considering the aggressiveness of the lesion and its proximity to important adjacent structures.

Oral eumycetoma of infancy: A rare presentation and a brief review

Mycetoma is a chronic granulomatous infection of skin and subcutaneous tissue, which may involve bone. The disease is caused by true fungi (eumycetoma) or filamentous bacteria (actinomycetoma). Both types of organism are important soil saprophytes, and therefore infection is normally acquired by traumatic inoculation of the skin by contaminated material. Clinically, mycetomas are characterized by tumefaction, draining sinuses and discharging grains. The grains are aggregates of fungal hyphae or bacterial filaments, and grain size, colour and consistency provide the initial clue to the causative organism. To our knowledge, this probably is the first case report of oral eumycetoma of infancy. Review of literature shows only ten cases of eumycetoma involving the head and neck, including the present case. Histological examinations of the biopsies were the cornerstone in the diagnosis of mycetoma. The distinction between eumycetoma and actinomycetoma is essential for treatment. Direct microscopic examination of the grain and histopathological examination, using histochemical staining will distinguish between the two. Treatment consists of long courses of antifungals and antibacterials agents, often combined with surgery.
