Primary pancreatic leiomyosarcomas are rare tumors of the pancreas that are usually diagnosed after resection or by biopsy. One case in the literature has utilized endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) cytology. We report a second case of a primary pancreatic leiomyosarcoma that yielded diagnostic material on EUS-FNA cytology. A 72-year-old female presented with 3-4 months of abdominal pain. A CT scan showed a large heterogeneous, lobulated pancreatic head and uncinate mass and multiple hypoattenuating liver lesions. An EUS-FNA was performed on one of the liver lesions with a 25-gauge needle, yielding an adequate sample with lesional cells. The initial read was a spindle cell neoplasm. A subsequent endoscopic ultrasound-guided fine needle biopsy with a 22-gauge needle was performed on the pancreatic head mass to rule out two primaries and to provide tissue for a mitotic index in the case of gastrointestinal tumor. Both the cell block of the EUS-FNA and the core biopsy were equally cellular and showed interlacing spindle cells that stained positive for SMA and negative for DOG-1, CD 117, and CD34. In addition, the core biopsy of the pancreas stained positive for Desmin. A diagnosis of a primary pancreatic leiomyosarcoma was made and the patient was started on systemic chemotherapy.

Pancreatic pheochromocytomas are rare and typically diagnosed by local resection.We present the first reported case of metastatic pheochromocytoma to the pancreas diagnosed by endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) and cytology.A 67-year-old female presented with 2 to 3 months of abdominal pain. A CT scan showed

Primary leiomyosarcomas of the colon (PLC) are rare tumors, representing 0.12% of all colon malignancies. We report a 59-year-old man with weight loss, mild anemia, and rectal bleeding. Colonoscopy revealed a 3.2 × 2.6-cm mass at the ileocecal valve. Histopathological examination of the biopsy showed a spindle cell neoplasm that stained positive for smooth muscle actin, caldesmon, and desmin. A diagnosis of PLC was made. Subsequently, a laparoscopic right hemicolectomy was performed, and no local recurrence was noted 6 months after the resection. Given the rarity of PLC, more studies on the clinical features and treatments of this tumor are warranted.

We present a 66-year-old female with a glomus tumor diagnosed by fine-needle aspiration (FNA) at the subungual region of her left second toe. Cytologic findings include cohesive clusters of round, uniform cells with scant cytoplasm. Nuclei were monotonous with fine chromatin. No cellular atypia, nuclear inclusions, mitotic figures, nor nucleoli were identified. Cells were surrounded by thick wisps of magenta colored myxoid material reminiscent of a pleomorphic adenoma. Few spindle shaped cells could be seen near the border of the tumor clusters. Staining was positive for alpha-smooth muscle actin. This case report presents one of few FNA diagnosed glomus tumors.
