Abstract Background Glomus tumors are subcutaneous tumors arising from glomus bodies, thermoregulatory components of the skin. These tumors could occur in visceral organs where glomus bodies are not normally present. Herein, we report a case of primary pancreatic glomus tumor with aggressive direct invasion into the superior mesenteric vein (SMV). To the best of our knowledge, this is the second case report of a glomus tumor arising in the pancreas. Case presentation A 46-year-old woman was referred to our hospital due to vomiting with epigastric and back pain. Dynamic-CT revealed a well-circumscribed hypervascular mass, measuring 37 mm in its maximal diameter involving the pancreatic head. Both CT and endoscopic ultrasonography (EUS) revealed direct invasion into the SMV and radiologically suspected tumor thrombus. Biopsy sample obtained by EUS-guided fine needle aspiration revealed proliferation of small cells, round-to-oval tumor cells with round nuclei and scant cytoplasm. A histological diagnosis of pancreatic neuroendocrine tumor, G1 was initially considered. Therefore, subtotal stomach-preserving pancreatoduodenectomy using Child-II reconstruction was subsequently performed. Her SMV was resected and reconstructed due to extensive tumor involvement. Subsequent histopathological analysis revealed solid tumor cells proliferation that comprised oval-shaped nuclei and scant cytoplasm around disorganized or slit-shaped vessels in hematoxylin–eosin-stained slides. Immunohistochemical analysis then demonstrated positive immunoreactivity for smooth muscle actin, vimentin, and CD34, but negative for chromogranin A, synaptophysin, CD56, and signal transducer and activator of transcription 6. Based on these histological findings of resected specimens, the lesion was subsequently diagnosed as a primary pancreatic glomus tumor harboring direct invasion into the SMV. Her postoperative course was uneventful and annual surveys for the following 4 years post-op detected no clinical signs of recurrence. Conclusions We report a very rare case of glomus tumor of the pancreas accompanied by venous invasion. Curative surgical resection is the best treatment option for pancreatic glomus tumors. Although pancreatic glomus tumor is rare, it should be taken into consideration in the differential diagnosis of a pancreatic solid tumor with hypervascularity.

Glomus Tumors

Abstract Introduction/Objective Glomus tumors are rare neoplasms arising from the glomus body which is a specialized arteriovenous anastomosis that has a role in temperature regulation of the skin. They account for less than 2% of soft tissue tumors and typically manifest as painful nodules in the extremities, most commonly in the subungual region of the fingers and dermis of the wrist, forearm, and foot. They rarely arise in visceral organs as they lack glomus bodies. There are rare case reports of benign glomus tumors arising in the kidney, and malignant renal glomus tumors are exceedingly rare. Methods/Case Report We present a case of a 32-year-old man who was found to have a right renal mass incidentally after being involved in a motor vehicle accident. Computed tomography of the abdomen revealed a 5.3 cm enhancing mass in the posterior aspect of the inferior pole of the right kidney. Histological examination revealed a solid neoplasm composed of a pleomorphic population of cells with densely eosinophilic to pale cytoplasm, centrally located round to oval nuclei with fine nuclear chromatin and relatively inconspicuous nucleoli. Prominent lymphovascular invasion and 1 mitotic figure per 10 high power fields were also present. Areas composed of necrosis, sclerosis, hemosiderin deposition and calcification were identified. Immunohistochemical stains revealed the neoplastic cells to be positive for CD34, vimentin, smooth muscle actin, caldesmon, with focal reticulin staining around the tumor cells. Cells were negative for desmin, high and low molecular weight cytokeratins, synaptophysin, chromogranin, PAX8, and GATA3. The morphology and immunoprofile of the mass are consistent with the diagnosis of glomus tumor. Results (if a Case Study enter NA) NA Conclusion Although very rare, the presence of prominent vascular invasion, increased mitotic activity as well as necrosis are consistent with malignant behavior and support the classification as a malignant glomus tumor.

AbstractGastrocnemius is a superficial muscle of the posterior compartment of leg. It usually arises by two heads- a medial and a lateral head. A third head of Gastrocnemius has been reported to occur in 2.9 - 5.5% of subjects. This anomaly has been implicated as a cause for popliteal vessel entrapment syndrome.Variations of the heads of origin of Gastrocnemius muscle were studied in 20 lower extremities of ten adult cadavers during routine Popliteal Fossa dissection at Sri Manakula Vinayagar Medical College and Hospital, Puducherry. An accessory third head of Gastrocnemius was found in four lower limbs (20% ). This third head originated along with the lateral head of Gastrocnemius.

Tumors Of The Hand

Glomus bodies are neuromyoarterial apparatuses of the skin, implicated in body temperature control, and may undergo transformation with unregulated hyperplasia of their smooth muscle component. Glomus tumors most commonly occur in the subungual region of the fingers. These benign tumors are rare and constitute 1-5% of soft tissue tumors of the hand and may present as solitary or multiple masses. Solitary glomus tumors present with a classic triad of localized tenderness, severe pain, and cold sensitivity. We report a rare case of glomus tumor in the elbow and a review of the histopathological findings.

Abstract Introduction/Objective Glomus bodies reside in the stratum reticularis of the dermis as well as in visceral organs. Their functions involve temperature and blood pressure regulation. The incidence of glomus tumors is approximately 1.5%, occur more frequently in women, and generally manifest during the third to fifth decade of life. A majority of glomus tumors are diagnosed by biopsy and excision. At least 19 case reports exist in the literature where glomus tumors are diagnosed by fine-needle aspiration (FNA). We add to this growing literature by discussing a case report involving the cytologic findings of an FNA-diagnosed glomus tumor. Methods/Case Report A 66-year-old female presented with left second toe pain for 41 years but worsening in the past several months. Physical exam revealed 5/5 muscle strength in her toes without loss of sensation. There was no edema, erythema, nor ecchymosis. Pain was notably out of proportion when palpating her second nailbed. Magnetic resonance imaging (MRI) with contrast was performed revealing a 1.1 x 1.0 x 0.9 cm circumscribed, ovoid mass involving the dorsal aspect of the second toe distal phalanx along its dorsal margin (Figure 1). The patient underwent fine needle aspiration and biopsy. Cytologic findings included clusters of uniform cells with round to oval nuclei and scant cytoplasm. There was spindling of cells noted in some of the clusters. Cells were surrounded by thick wisps of magenta colored myxoid material reminiscent of a pleomorphic adenoma (Figure 2). Biopsy showed uniform cells surrounding capillaries. Immunohistochemistry performed on the biopsy showed that lesional cells were positive for alpha-smooth muscle actin (SMA). A diagnosis of glomus tumor was made. Amputation was performed with clear margins. Results (if a Case Study enter NA) NA Conclusion Glomus tumor is a rare tumor that is usually diagnosed on biopsy; however, it has distinct cytologic features that can aid in its diagnosis on fine needle aspirations.

AbstractIntroduction: Glomus tumors are rare benign mesenchymal neoplasms accounting for only 2% of all types of soft tissue tumors. Commonly located in the peripheral soft tissues, they are most frequently encountered in the subungual areas of fingers and toes, and very rarely in visceral organs due to the absence of glomus bodies. To date, 22 cases of primary renal glomus tumors have been described in the literature, of which 17 benign, with no evidence of recurrence or metastasis, three cases of malignant glomus tumor, and two cases with uncertain malignant potential. Case report: We report the 18th case of a benign glomus tumor of the kidney in a 49-year-old female patient, presenting the microscopic appearance (round, uniform cells with indistinct borders, scant finely granular eosinophilic cytoplasm, round nuclei lacking prominent nucleoli, arranged in solid sheets, accompanied by slit-like vascular spaces), the immunohistochemical profile (tumor cells showed immunoreactivity for smooth muscle actin, vimentin, as well as for CD34; they were negative for AE1/AE3, desmin, HMB-45, S-100 protein, renin, and chromogranin), and the differential diagnosis of this rare entity (juxtaglomerular tumor, angiomyolipoma, hemangioma, epithelioid leyomioma, solitary fibrous tumor, carcinoid tumor, and paraganglioma). Conclusion: Primary renal glomus tumors are rare tumors that radiologically can mimic other mesenchymal renal neoplasm. Accurate diagnosis is based on the microscopic appearance and especially the characteristic immunophenotype.
