A 20-year-old woman presented with 2-year history of low back pain. She is a basketball player. There was neither major traumatic episode nor history of febrile illness, On plain roentgenograms, sclerosis and slightly decreased height of L5 vertebral body was detected while the intervertebral disc spaces were intact. We found that L5 body was destructed by materials showing high signal intensity on T2 weighted images and connecting the two adjacent disc spaces on MRI. The initial diagonsis included bone tumors. Vertebrectomy was done and the intravertebral material was revealed as degenerated nucleus pulposus.

Benign lichenoid keratosis is an asyrnptomatic, isolated, plaque-like lesion frequently mistaken for basal cell carcinoma, Bowens disease, and actinic or seborrheic keratosis because of its variable clinical appearance. We present two cases of benign lichenoid keratosis. The first case was a 44-year-old female who had mild pruritic, ll x15rnrn sized, single, slightly elevated brownish plaque with fine scaling on the right zygornatic area of 5 years' duration. The second case was a 35-year-old female who had mild prutitic, single, pea- sized erythernatous patch on the left ala nasi of one month's duration. On histologic examination, these two cases showed same histologic findings, such as focal parakeratosis, moderate hyperkeratosis, irregular acanthosis and liquefaction degeneration of basal cells in the epidermis and band-like mononuclear infiltration and colloid bodies in the dermis.

Melanoacanthoma is an extremely rare pigmented benign mixed epithelial tumor of both melanocytes and keratinocytes. A 52-year-old female presented an asymptomatic, slightly elevated, 1. 2 cm x 0. 8 cm, dark black-colored plaque on her right buttock of 2 years' duration. Histopathologic finding of the plaque shows hyperkeratosis, focal parakeratosis, follicular plugging, acanthosih, papillomatosis and pseudo-horn cyst in the epidermis. The tumor is composed of basaloid and squarnous cells with many foci of clusters and whorls of melanin pigment-laden cells. Electron microscopic finding reveals many scattered melanocytes in the entire epidermis. Melanin granules are found mostly in the melanocytes but can also be found in a few keratinocytes.

Epidermal nevus syndrome is now delineated as a congenitally acquired syndrome consisting of deformities of the skin (various linear epidermal or organoid nevi), central nervous system, skeleton, cardiovascular system, and renal system. A 4-year-old girl had linear epidermal nevus on the right lower extremity, right ear lobe and anterior neck, and multiple skeletal abnorrnalities since birth. And she had an adult fist-sied, soft, nontender mass on the right lower abdomen since 2 years of age. Radiologic examination showed scoliosis of the thoracic spines, deformities of the lumbar spines, focal gigantisms of the left hand and right foot, and other skeletal abnormalities. Histological examination of the linear, verrucous lesion of the right leg showed hyperkeratosis and papillomatosis. The surgically removed abdominal mass revealed the finding of hydrosalpinx.
