Large intramuscular spindle-cell lipoma. With review of the literature. A case report.

A case of a large spindle-cell lipoma in an intramuscular (subfascial) localization is reported. The tumour occurred in a 58-year-old male patient and was localized subfascially in his left deltoid muscle. The tumour measured 20 X 8 X 8 cm; its weight was 780 grams. After initial biopsy, the tumour was extirpated. Microscopically, the tumour tissue consisted of mature fat cells and spindle-cell areas in varying amounts, constituting a typical appearance of a spindle-cell lipoma. There were no histological signs of malignancy. Especially, no areas of liposarcoma differentiation were detected. The patient is well, with no signs of recurrence, one and a half years after the operation. We have reviewed the literature on spindle-cell lipoma, and we believe this is the first example of this neoplasm to be reported in an intramuscular (subfascial) localization.

Prevalence of ankylosing spondylitis in males and females in a young middle-aged population of Tromsø, northern Norway.

In an epidemiological survey in Tromsø, northern Norway a prevalence of definite ankylosing spondylitis (AS) of between 1.1% and 1.4% was found (males: 1.9-2.2% and females: 0.3-0.6%). The ratio of male to female was between 3.9 and 6.1 in favour of the male sex. It was calculated that 6.7% of the B27 positive individuals had AS, and that 22.5% of the B27 positive subjects with back pain or stiffness suffered from AS.

Spinal ankylosing spondylitis: a variant form of ankylosing spondylitis or a distinct disease entity?

In a population survey of ankylosing spondylitis (AS) seven subjects, six males and one female, had x-ray changes in the lumbar spine typical of AS but without concomitant roentgenological sacroiliitis. The overall prevalence of such cases in the population studied was 0.37%. Four out of these seven subjects carried the tissue antigen HLA-B27 (57%). The clinical and roentgenological features of these subjects are described and it is suggested that the x-ray findings represent a mild and variant form of primary or definite AS.
