PATHOLOGY REPORT GROSS:
The specimen labeled with the patient's name, "Peritoneal biopsy," consists of a 2 x 1.5 x 0.3 cm whitish soft tissue piece. It is submitted all in one cassette.
The specimen fixed and labeled with the patient's name, "Omental biopsy," consists of 2 yellowish fatty tissue pieces, in aggregate measuring 3 x 3 x 0.5 cm. They are submitted all in 2 cassettes.
MICROSCOPIC:
Peritoneal and omental biopsies reveal similar findings, with infiltration by multiple, variably sized caseating and non-caseating epithelioid granulomas and scattered Langhans-type multinucleated giant cells. Z.N stain for acid-fast bacilli is negative. No malignancy was seen in the levels examined.
DIAGNOSIS: (1&2) Peritoneal and omental biopsy:
Granulomatous inflammation, including caseating epithelioid granulomas, is most in keeping with tuberculosis.
