Abstract

Background: Urachal masses observed in adults
should be considered malignant unless they are confuted.
It is very difficult to differentiate between malignant
or benign lesions, including especially calcified
foci and solid areas.
Case Report: Our case was a 63-year-old male patient
who was diagnosed as Behçet’s Disease 26 years ago.
Upon clinical examination, he was also diagnosed with
adenocarcinoma of prostate. He was examined by computerized
tomography to define the stage of prostatic
adenocarcinoma. The existence of a hypodense multiseptated
cystic lesion with irregular margins and solid
areas located between anterosuperior of bladder and
umbilicus was reported. Hence, the lesion was evaluated
as urachal carcinoma and locally advanced prostate
cancer by the urooncology council. Resection of the
mass, partial cystectomy and pelvic lymphadenectomy
were performed as one of the surgical approach options
in urachal carcinoma. After pathological examination,
the mass was diagnosed as malakoplakia and metastasis
of prostate adenocarcinoma was also detected in
the right obdurator lymph nodule. In the literature, case
reports of urachal malakoplakia are extremely rare. It
is also interesting to note the absence of specific clinical
symptoms for the urachal mass and the existence of
concomitant adenocarcinoma in our case.
Conclusion: Malakoplakia can only be diagnosed by
pathological examination. Particularly, urachal malakoplakia
should also be taken into consideration in the
differential diagnosis of lesions which include solid areas
and are located in the urachus
