SUPERFICIAL ANGIOMYXOMA OF THE RIGHT INGUINAL REGION - REPORT OF A CASE

We report one rare case of superficial angiomyxoma of the right inguin al region, in a 67-year-old man, The tumor, measuring 4.5 x 4.0 x 3.0 cm, had a finger-like shape, was composed of a well circumscribed cong lomerate of multiple myxomatous nodules and was located partially in t he dermis and partially in the subcutaneous tissue, Microscopically, i n contrast to previously reported cases, the tumor was composed mainly of oval plump stromal cells with an amphophilic cytoplasm, Spindle-sh aped stromal cells were scattered throughout the tumor, The tumor bord er was not infiltrative and was well defined by thick hyalized collage n bundles. Neither hyperchromasia nor pleomorphism was apparent, No mi totic figures were detected in the specimens prepared, Small to medium -sized blood vessels showed a scattered distribution, but large vessel s, seen frequently in aggressive angiomyxoma, were absent, Moreover, n o plexiform capillary pattern was evident, These findings were diagnos tic of superficial angiomyxoma, Although this disease entity is consid ered as including cutaneous focal mucinosis, follicular fibroma, trich ofolliculoma and trichogenic adnexal tumor, we propose that these tumo rs should be excluded.
