耳介後部 Verrucous Carcinoma의 治驗例 : A Case Report = Verrucous Carcinoma of the Postauricular Area

다국어 초록 (Multilingual Abstract)

Verrucous carcinoma is a distinctive, slowly growing fungating tumor representing a well differentiated squamous cell carcinoma of skin and mucous membraned that are locally aggressive and destructive but only rarely metastasize.
It was originally described by Ackerman as an indolent tumor of the oral cavity often arising in elderly tobacco chewers.
Verrucous carcinoma, although manifesting somewhat different clinical patterns on the mouth (oral verrucous carcinoma, or oral florid papillomatosis) on the genitalia (giant condyloma acuminatum), and on the extremities (carcinoma cuniculatum), is essentially the same neoplasm occurring in different anatomic sites.
The relatively benign histologic appearance of verrucous carcinoma has made come authors hesitant to interpret their casesas cancer and has contributed to the profusion of terms under which this condition has been described.
Histologic criteria consisted of a papillary or verrucous, well differentiated epidermoid carcinoma with swollen and voluminous rete pegs, and with evidence of extension into deeper tissues.
Regional lymph node metastasis are extremely rare and distant metastasis arise very late or not at all, so that prognosis is favorable when complete excision is affected.
The most satisfactory form of therapy is surgical excision which is adequate to encompass the primary lesion.
Authors report a case of verrucouse carcinoma on right postauricular region. The patient was 47 year old male.
The large hen egg sized verrucous tumor was locally excised with cervical lymph node dissection and the defect was covered with medium split thickness skin graft from left thigh.
