We report a case of transitional cell carcinoma of the fossa navicular
is in an elderly white male, The patient presented in urinary retentio
n, with a large exophytic mass at the external urethral meatus. Both t
he pathogenesis and natural history of this highly unusual tumor are u
nclear. Treatment depends on grade and stage of disease. Transurethral
resection and fulguration have been successfully used to treat superf
icial lesions. Segmental resection and partial penectomy, with or with
out inguinal lymph node dissection, form the mainstay of treatment for
invasive disease. The role of chemotherapy for advanced disease is un
known. (C) 1997, Elsevier Science Inc. All rights reserved.
