Low-grade spindle-cell ameloblastic carcinoma: report of an unusual case with immunohistochemical findings and review of the literature.

Spindle-cell differentiation in ameloblastic carcinoma is a rare event. Although reported by many authors, it was first described as a separate entity in 1999 by Slater under the heading "low-grade spindle-cell ameloblastic carcinoma." Here, we report a case of low-grade spindle-cell ameloblastic carcinoma arising in pre-existing unicystic ameloblastoma.

Vanishing mandible.

Massive osteolysis is a rare, insidious, chronic disease characterized by progressive resorption of contiguous osseous structures. In 1838 Jackson first described a case of disappearing humerus. More than 150 cases have since been described in the international literature, with fewer then 35 involving a maxillofacial site, usually the mandible.

Intraosseous calcifying cystic odontogenic tumor.

The calcifying odontogenic cyst was first reported by Gorlin et al. in 1962. It had been classified as a neoplasm related to the odontogenic apparatus because of its histological complexity and morphological diversity until it was renamed as a calcifying cystic odontogenic tumor by the WHO, in 2005.

Rhinomaxillary mucormycosis with cerebral extension.

Mucormycosis is a rare opportunistic infection caused by fungus belonging to the order Mucorales. A case of a controlled diabetic male with rhino maxillary mucormycosis, with cerebral extension, is described. The patient presented with hemifacial swelling, a nasal twang in his voice, fever, ocular signs, gross tissue destruction, and was sluggish.

Hemifacial microsomia: a case report.

Hemifacial microsomia is a congenital malformation in which there is a deficiency in the amount of hard and soft tissue on one side of the face. It is primarily a syndrome of the first branchial arch, involving underdevelopment of the temporomandibular joint, mandibular ramus, masticatory muscles and the ear. The affected ear may have an external soft-tissue malformation in addition to being lower set than on the contra lateral side.
