   Case Report Top

A 44-year-old male. chronic smoker. working in a dye industry for 14 years presented with obstructive voiding symptoms. Abdominal and rectal examination was normal. Ultrasonography revealed 3.9 x 3.0 cm bladder mass along right posterolateral wall. CT scan showed a welldefined, smooth-surfaced soft tissue mass arising from right posterolateral bladder wall showing mild enhancement on injection of contrast. There was no lymphadenopathy or perivesical infiltration. Metastatic evaluation was unremarkable. Cystoscopy revealed a mass on right posterolateral wall with a broad pedicle, bosselated surface and intact mucosa. Rest of the bladder was normal and there was no outlet obstruction. Biopsy was deferred in view of well circumscribed nature of the lesion. Partial cystectomy was performed to excise the mass with adequate margin of normal bladder. On gross examination. mass was well circumscribed, broad based, nodular, firm and pale tan. It cut with a gritty sensation and showed a capsulated mass of grayish white tissue. Microscopy showed interlacing fascicles of spindle cells possessing bright acidophilic cytoplasm and elongated plump nuclei. No mitotic activity or nuclear anaplasia was seen. Cells were intimately associated with broad, glassy bands of collagen. Diagnosis of Desmoid tumour of urinary bladder was thus made.

   Comment Top

Desmoid tumour of urinary bladder is not reported in literature. Smoking and chemical exposure are not associated with intra-abdominal desmoid tumours. Differential diagnosis included spindle cell sarcoma and pseudosarcomatous fibrornyxoid tumour[1] The former shows nuclear anaplasia and mitotic activity and latter follows injury to bladder and shows myxoid component, a few mitoses and inflammatory infiltrate.[2],[3] The tumour reported here did not show these features. The patient needs a close follow-up because of recurrence reported with Desmoid tumours
