A 58 yr old postmenopausal woman presented to the department of Surgical Oncology, Dayanand Medical College & Hospital, Ludhiana, India, in July 2016, with lower abdominal pain and an antecedent history of total abdominal hysterectomy with bilateral salpingo-oophorectomy done for uterine leiomyoma and ovarian fibroma. Although radiology was suggestive of disseminated intraperitoneal malignancy [Figure 1], histopathological [Figure 2]A and immunohistochemical examination showed positivity for smooth muscle actin [Figure 2]B and oestrogen [Figure 2]C and progesterone [Figure 2]D receptors, thus revealing leiomyomatosis peritonealis disseminata which grossly mimiced disseminated malignancy but was histologically benign otherwise. Plan for surgery was deferred, and the patient was put on tamoxifen. At one year follow up, the patient remained asymptomatic without any radiographic disease progression. A pathological evaluation is crucial for the diagnosis, surgery is not always needed and close surveillance is a necessity rather than a recommendation.
