A Case of Penile Cutaneous Metastasis from Gastric Carcinoma / 대한피부과학회지

ABSTRACT

Metastatic carcinoma of the penis is rare and in most cases is associated with primary malignancy of the pelvic organs with widespread metastasis. A 64-year-old man presented with a 2 month history of skin-colored papules on his penis. He also had a history of total gastrectomy and chemotherapy due to advanced gastric carcinoma. Skin biopsy from the lesion revealed atypical polygonal cells with hyperchromatic & pleomorphic nuclei in the dermis. Results of immunohistochemical staining showed a positive reaction of CK7, and a negative reaction of CK20, PSA, and CD68. We report herein a case of metastatic cancer of the penis from gastric carcinoma.
