An 84-year-old female presented with a 3-month history of asthenia, weight loss, and diffuse abdominal pain. Her medical history was remarkable for high-grade breast leiomyosarcoma (Ki67 25%, 5.5 × 4 × 3.5 cm) excised 6 years before (R1), with no recurrence during follow-up. Physical examination was significant for pallor and abdominal tenderness, and laboratory workup demonstrated anemia (Hb 5.4 g/dL) and elevated lipase (267 U/L) with normal liver function tests. Ultrasound and a CT scan revealed multiple solid hepatic lesions, the largest measuring 7 × 5 cm, a 3-cm pancreatic cephalic mass lesion, and a 3.1 × 2.5 cm endoluminal mass in the gallbladder (Fig. 1). Differential diagnosis included gallbladder and pancreatic cancer (eventually synchronous, with liver metastases) and late recurrence of the primary leiomyosarcoma of the breast with liver, gallbladder, and pancreatic metastases.

 

 

Endoscopic ultrasound identified solid liver nodules and multiple pancreatic hypoechogenic, well-defined nodules, the largest measuring 35 mm in the cephalic region, consistent with multifocal pancreatic metastization, and a heterogeneous hypoechoic gallbladder mass (Fig. 2). Endoscopic ultrasound-guided fine-needle biopsy of the largest pancreatic lesion using a 22-G needle (AcquireTM; Boston Scientific) was performed. Pathology documented fusiform neoplastic cells with numerous mitosis, and immunohistochemical staining was positive for actine, desmine, vimentin, and caldesmon and negative for CK AE1AE3, Cam 5.2, S-100, and CD99, consistent with pancreatic metastasis from leiomyosarcoma (Fig. 3). The patient was referred to a palliative care unit.

 

 

 

Metastatic gallbladder and pancreatic disease are extremely uncommon in clinical practice [1, 2]. Melanoma, renal, and cervix cancer are the most common primary cancers associated with gallbladder metastases [1]. Metastatic lesions of the gallbladder from primary breast tumors are rarely described, and most of those have been associated with a lobular histology [1]. Only 2% of all pancreatic malignancies are metastases, and the most common primary cancer site responsible for pancreatic metastasis is the kidney, followed by colorectal cancer, melanoma, breast cancer, lung carcinoma, and sarcoma [2]. Leiomyosarcoma represents an exceedingly rare cause of pancreatic metastasis [3–5], with the primary organs being the uterus, ovary, veins, spermatic cord, intestine, retroperitoneum, and soft tissue [4]. Primary leiomyosarcoma of the breast is an extremely rare form of breast cancer (< 0.01% of all cases) with an unpredictable biological behavior [5]. To the best of our knowledge, synchronous pancreatic and gallbladder metastasis from breast leiomyosarcoma has never been reported.
