Dikkat, Cildin Adenoid Kistik Karsinomu Var!

Abstract

Unusual skin malignancies other than squamous cell or basal cell carcinoma are very uncommon.1,2 Primary cutaneous adenoid cystic carcinoma (PCACC) is one of these rare skin neoplasms with a high potential for recurrence after local excision.3 Unexpected localization and the aggressive nature of the tumor led us to notify other professionals. Sixty-two year-old male patient, previously received chemoradiotherapy for resectable T3,N0,M0 gastric adenocarcinoma referred for adenoid cystic carcinoma of the scalp. Review of the pathology of the excised specimen excluded metastasis. As a separate entity, local excision was performed (Figure 1). However, surgical margin on the deep side of the lesion was positive for tumor. For this reason the patient received 60 Gy of external radiotherapy in 30 fractions with 6 MeV electron beams. No acute reaction excluding mild erythema was observed as a side effect. During follow-up period of one year, physical findings and imaging studies were completely normal. After that, the patient complained of severe pruritus on the radiotherapy site. Despite the fact that there was no evidence of disease relapse, second surgery was performed since there was a high risk of recurrence. Pathology report excluded presence of tumor.
