Submandibular cavernous hemangiomas with multiple phleboliths masquerading as sialolithiasis.

Vasoformative tumors (almost exclusively hemangiomas) are the most common lesions of the major salivary glands during infancy and early childhood. They are more common in the parotid gland but are particularly rare in the submandibular gland. Changes in blood flow dynamics within hemangiomas result in thrombus formation and phleboliths. Hemangiomas of the salivary glands in adults are histologically unlike those in infants, the former being characteristically of the cavernous variant. Most cavernous hemangiomas require surgery since they do not show a tendency to regress. A case of an adult man with cavernous hemangioma affecting the submandibular salivary gland that clinically simulated sialolithiasis is presented to alert surgeons to the possibility of such a lesion. We describe the clinical course and review the literature.

Madelung's disease.

Madelung's disease is a rare disease of undetermined cause characterized by symmetric deposits of painless, diffuse, subcutaneous adipose tissue on the suboccipital area, the cheeks, the neck, the shoulders and the upper trunk. It is commonest in countries bordering the Mediterranean. The patients are usually middle-aged male alcoholics. Although lesions can initially mimic a head and neck malignancy, management is essentially symptomatic, with conservative removals done as indicated clinically or for cosmesis. Oriental reports about Madelung's disease are very rare. Here a case of Madelung's disease in a 59-year-old male is described. We describe his clinical course and review the literature.

Pilomatrixoma of the head and neck.

Pilomatrixoma is a benign skin appendage tumor that commonly occurs as a solitary lesion and is not usually hereditary. There is evidence to suggest that patients with a family history of multiple pilomatrixomas have a high probability of autosomal dominant disorders such as myotonic dystrophy, Gardner syndrome, and Rubinstein-Taybi syndrome. In January 2004, a case was reported of an 8-year-old girl with 2 progressively enlarged facial masses. One of them was excised and diagnosed as pilomatrixoma. Coincidently, her 13-year-old sister had the same type of tumor when she was 4 years old. We report this unusual case and review the literature. Pilomatrixoma has not been widely reported in the head and neck surgery literature. This benign tumor may be misdiagnosed as a carcinoma, resulting in unnecessary aggressive therapy. Otolaryngologists should therefore note the clinical and pathologic characteristics of these symptoms.
