Left Maxillary Sinus

Giant cell tumors are rare benign borderline tumors, and maxillary localization is extremely rare. Because of the few clinical cases, healing behavior is very different, although the primary is the surgery. We present a 72-year-old man in which, on the occasion of difficulty left nasal breathing with four months of length, in January 2021 an operation was carried out on a left maxillary sinus. Histological diagnosis is a giant cell tumor (GCT) of the maxillary sinus.The patient is targeted for post-operative radiotherapy (RT).

We describe a patient with a giant cell tumor in the talar head and neck of the left foot who was diagnosed as having osteochondritis dissecans and treated with arthroscopic drilling in this same location 3 years earlier. Giant cell tumors can be confused with several conditions, including giant cell reparative granulomas, brown tumors, and aneurysmal bone cysts. Giant cell tumors of bone typically occur in the epiphysis of long bones, including the distal femur and proximal tibia. They are uncommonly found in the small bones of the foot or ankle, and talar involvement is rare. Despite this rarity, the radiographic appearance and clinical signs of talar lesions should be considered in the differential diagnosis of nontraumatic conditions in the foot.

Tenosynovial Giant Cell Tumor

Tenosynovial giant cell tumors typically arise in the synovium of joints, bursae, or tendon sheaths. They may occur in an intra- or extra-articular location and can be divided into localized and diffuse types. The neoplastic nature of the lesion has been supported by a recurrent CSF1 gene rearrangement in a small subset of lesional cells, of which the most common fusion partner is COL6A3. Herein, we report a case of intramuscular localized tenosynovial giant cell tumor harboring a novel CSF1-CD96 fusion transcript, thus expanding the molecular profile of this tumor.

Giant cell tumor of bone is considered by his behavior a benign but aggressive neoplasm. The objective of our study was to determine if there is a correlation between the Campanacci’s radiological classification of giant cell tumors of bone and the expression by immunohistochemistry of Cyclin D1 and proliferation cell nuclear antibody (PCNA). A retrospective and descriptive study was made. In total, there were 27 cases. All cases showed Cyclin D1 and PCNA positivity. Rho Spearman for Campanacci and Cyclin D1 expression was 0.06 and for Campanacci and PCNA was 0.418. We conclude that there is a positive correlation between PCNA expression in giant cell tumors of Bone and the Campanacci’s radiological classification II and III, butCyclin D1 expression was no related with radiologic features.

Background: Aggressive musculoskeletal tumors in the foot, such as diffuse-type giant cell tumors or extra-abdominal desmoid tumors, are difficult to treat because the foot does not have enough soft tissue to allow wide tumor resection. We reviewed the clinical behavior of diffuse-type giant cell tumor in the foot and evaluated the recurrence potential of these tumors from radiologic and pathologic perspectives. Methods: Six patients with a mean age of 37.6 years were included in this study. Radiologic studies, including sonography, computed tomography (CT), magnetic resonance imaging (MRI), and bone and gallium citrate scintigraphy, were obtained followed by surgical treatment and histologic evaluation of the tumor. Results: Recurrence occurred in three patients. Although CT and MRI findings were similar in the recurrent and nonrecurrent tumors, marked differences were found between the two by scintigraphy; positive radiotracer uptake to the affected foot with gallium citrate scintigraphy was noted only in recurrent tumors, although positive accumulation was seen in all patients with bone scintigraphy. Histologically, the necrotic area and mitotic activity were more apparent in recurrent than in the nonrecurrent tumors, and tumor cell dyscohesion was noted in the former, (the intercellular space was increased). Conclusions: Repeated recurrence with tumor invasion into tarsal bone resulted in breakage of the tarsal arch that supports the body's weight. Amputation would be necessary for patients in whom the disease had progressed to obtain local cure and relief of pain. In the present study, we found two features of the recurrence potential of diffuse-type giant cell tumors: sparse cell to cell contact on pathologic examination and positive accumulation in the tumor on gallium citrate scintigraphy. We concluded that giant cell tumors with these two features have a strong potential for local recurrence, and thus require intensive followup.

True Neoplasm

Among the more uncommon tumors that may sometimes be encountered in the laryngeal region is the recently described giant cell tumor of the larynx. This lesion is a true neoplasm, presumably of the fibrohistiocytic series. Histologically, it closely resembles the more familiar true giant cell tumor of long bone. The laryngeal giant cell tumors appear, to date, to be nonmetastasizing lesions; it is possible that they may recur locally if incompletely excised (although this remains to be demonstrated). In view of the rarity of these tumors, a tentative diagnosis of such a neoplasm should always prompt consideration of other (more frequently encountered) differential diagnostic possibilities, including cytologically malignant giant cell-rich tumors such as malignant fibrous histiocytoma and sarcomatoid carcinoma.

Patients of Giant cell tumors (GCT) of the spine is rarely seen . We reported a case of GCT of the eleventh dorsal vertebra presented by severe backache with paraplegia in a 30 year old woman. Imaging showed an osteolytic lesion invading the vertebral body, the posterior arch and compression of the spinal cord. Neurological decompression was performed but pain recurred after 2 months. The MRI of spine revealed recurrence of tumor and again surgical decompressions was done along with long segment transpedicular fixation and patient was significantly improved. A surgical biopsy was obtained at the same time to confirm the diagnosis. Giant cell tumor is not so common in thoracic region. We believe that the gross removal of tumor provide good outcome for the patient. Bangladesh Journal of Neuroscience 2015; Vol. 31 (1): 45-49

Multinucleated giant cells resembling osteoblasts seen in giant-cell tumors of bone have been described in the thyroid gland, and pancreas. However, a giant cell tumor of the lung with osteoblast-like cells is rare. The present report will describe ultrastructural aspects and histiogenesis of this type of lung tumor.A 58-year old white male patient was noted by chest x-ray to have a mass in the right lower lobe of the lung. Segmental resection of the superior segment was performed revealing a nodular neoplastic lesion of 3.5 cm in diameter located 4.3 cm from the bronchial resection margin. For EM preparation, the tissue samples were immediately fixed in 4 percent phosphate-buffered glutaraldehyde and postfixed 1 hr with 1 percent osmium tetroxide in phosphate buffer (pH 7.2), dehydrated in ethanol and embedded in Epon 812. The tumor presented a sheet-like growth pattern without evidence of encapsulation.
