皮下浸潤をきたした陰茎ボーエン病

BOWEN'S DISEASE OF THE PENIS AGGRAVATED BY IMPROPER TREATMENTS

　患者は58歳男性．2年前，陰茎冠状溝腹側に発疹を認め，近医で2回にわたり切除縫合を受けたが治癒しなかった．その後，悪化して潰瘍を形成したため当院を受診した．生検の結果ボーエン病と判明．潰瘍部分にも癌細胞の浸潤を認めたため，扁平上皮癌として対処した．病変部より10mm離して尿道および陰茎海綿体の一部を含めて患部を切除した．術後，立位排尿可能で尿道狭窄なく，また局所再発を認めていない．

We presented a 58-year-old male who suffered from Bowen's disease of the penis. He had recognized skin eruption at the penile frenulum two years ago and had dermal eruption resected twice before visiting our clinic. The wound did not heal and developed to ulcer. Since dermal biopsy at the ulcer revealed Bowen's disease, we decided to treat it as squamous cell carcinoma of the penis. Leaving 10 mm safety margin from the ulcer, a partial resection of the penis was performed. At present he voids at standing position without outflow obstruction. There has been no sign of recurrence.
