Three cases of Multiple Angiolipoma are presented.
Case 1:
A 51-year-old man, complaining of tumors on both arms and back, visited our clinic on October 2, 1989.
In 1970, he had noticed a subcutaneous tumor on the flexor side of his right forearm.
After that, many tumors appeared symmetrically on both arms and some of them were painful.
In 1980, he noticed many tumors on his back.
There were a total of sixty five tumors with a size of 0.5cm to 1.0cm, a smooth surface and elastic hard consistency, on both arms and the back.
Almost half were tender.
On October 5, 1992 biopsy was performed, but the patient did not wish for any additional treatment.
Case 2:
A 31-year-old man, complaining of tumors on both legs and low back, visited our clinic on August 11, 1992.
In the beginning of August 1992 he had noticed some painless subcutaneous tumors on both legs and low back.
There were a total of eleven tumors with a size of 0.5cm to 1.0cm, a smooth surface and elastic hard consistency, on the flexor side of his left upper arm, low back, upper abdomen and both legs.
A tumor of the right back was tender.
On October 6, 1992 surgical excision of all tumors was performed. They were in the subcutaneous tissue and similar to lipoma.
There was no reccurence, when he was reexamined on October 14, 1992.
Case 3:
A 32-year-old man, complaining of multiple tumors on both arms and legs, visited our clinic in December, 1996.
In 1992, he had noticed a painless subcutaneous tumor on the flexor side of his left forearm.
After that, the size of the tumor gradually increased and two tumors appeared at the proximal side of the first tumor.
In 1995, six tumors appeared on the right forearm and both legs.
There were total number of 9 tumors with a size of 1.0cm to 3.0cm, a smooth surface and elastic soft consistency, on the extremities.
All tumors had slight tenderness.
On December 20, 1992 surgical excision of all tumors was performed. They were in the subcutaneous tissue capsulated with a thin membranous tissue and similar to lipoma.
There was no reccurence, when he was reexamined on February 8, 1997.
Pathological diagnosis of all cases was angiolipoma.
Tumors were capsulated with a thin membranous tissue and composed of mature adipose tissue and varying amounts of capillaries, which contained variable amount of micro thrombosis.
