A case of acrospiroma / 대한피부과학회지

ABSTRACT

A healthy 12-year-old girl had noted over 2 years a gradual-growing painless nodule on the area below the right axilla. The lesion measuring approxima;ely 1.2 x 1.2 x 0.4cm in size, had a reddish-blue colored ulcerative papule raised on its cente with mucous discharge to compression. Histopathelogically, a circumscribed solid tumor located in the deep dermis, revealed the predominnntly epidermoid features of polyhedral cells, with the mucous cells within and at the peripiiery of the tumor. The mucous cells exhibited diastase-resistant PAS -positive, alcian-blue reactive at pH 2.5 and mucicarmine-positive reactions. Results of irnmunoperoxidase staining for cytokeratin and carcinoernbryonic antigen were focally cytoplasmic-positive, while negative for S-100 protein and epithlial membrane antigen. She has remained free of disease one year following excision.
