[Examination of regional limph nodes in penile carcinoma by 99M Tc-MIBI scintigraphy].

99mTc-MIBI scintigraphy has proven utility as a clinically valuable technique for the diagnosis of various primary and recurrent malignant lesions. We report the case of a 65 year old man with penile squamous cell carcinoma and clinically questionable bilateral inguinal lymph nodes. 99mTc-MIBI scan shows increased focal uptake in both groins and in the right iliac region. The patient underwent penile amputation with bilateral lymphadenectomy. Histopathologic report revealed metastatic lymph nodes in all lymphatic basins seen with 99mTc-MIBI. We conclude that this technique has the potential of supplying clinically relevant information for the diagnosis of regional extension of patients with penile carcinoma.
