ABSTRACT
Neurilemmoma is a benign neoplasm arising from the Schwann cell of the nerve sheath. Acoustic nerve is the most common site of neurilemmoma and mandible is the most frequently involved in intraosseous neurilemmoma. Extradurally located dumbbell type neurilemmoma was rarely reported. The histology of neurilemmoma was first described by Verocay in 1908 and elaborated upon by Stout in 1935. Characteristic histologic patterns of neurilemmoma were encapsulation and Verocay bodies, Antoni type A and B areas, palisading nuclei, and lack of malignant characteristics. We experienced such a rare case of neurilemmoma which probably arised from the left first lumbar spinal nerve root, and located extradurally and paravertebrally, and confirmed by radiologic and pathologic findings.

Hypokalemic familial periodic paralysis is one of the rare familial disease characterized by recurrent and transient attacks of weakness or paralysis of the somatic musculature. Also, this disease is usually inherited as an autosomal dominant trait in most cases. During an attack, the plasma potassium falls as a rasults of shift of potassium from the extracellular to the intracelluar compartment, but there is no loss of total potassium from the body. We have experienced hypokalemic familial periodic paralysis recently which affected 4 members in a family,and report this disorder.

Polands syndrome is a congenital disorder associated with thoracic anomalies and ipsilateral syndactly. It was described first by Alfred Poland in 1841 year. We has been experienced 2 cases of Polands Syndrome recently. Two cases were male. Each case revealed one side thoracic muscle anomalies, that is, absence of sternocostal head of pectorails major with hypoplasia of nipple and, breast, and ipsilateral syndactyly with partial aplasia and hypoplasia of midphalanges.
