Osteoclast like-giant cell tumor of the salivary gland is an extremely rare tumor with distinct pathological features and unknown histogenesis. The neoplastic nature of these tumors in itself is questionable. We present the twentieth case in English literature of primary osteoclast like-giant cell tumor with accompanying low to intermediate grade salivary duct carcinoma of parotid gland, metastasizing to the ipsilateral cervical lymph node. As far as we know this is the second case with lymph node metastasis. Due to the rarity of the tumor its exact biological course is uncertain. We present and discuss this rare case with special emphasis on the histology, immunohistochemistry, and histogenesis.

Breast carcinoma is the most common cancer in women. Nineteen different subtypes of breast carcinomas are recognized in the current WHO classification of breast tumors. Except for these subtypes, there are a number of carcinomas with special morphologic and immunohistochemical features that are not included in the 5th WHO classification, while others are considered special morphologic patterns of invasive breast carcinoma of no special type.

Urothelial carcinoma of the bladder with osteoclast-like giant cells (UCOGCs) is rare among the subtypes of poorly differentiated urothelial carcinoma. Its clinical significance and optimal treatment are unknown, and few reports on genomic analysis of UCOGCs have been reported. Detailed analysis including genetic analysis for rare type variants of cancer could be a foothold for further research.

Undifferentiated carcinoma with osteoclast-like giant cells of the pancreas (UCOGCP) is a rare pancreatic tumor that accounts for less than 1% of all pancreatic malignancies. The characteristic pathological manifestation of UCOGCP is the presence of osteoclast-like giant cells (OGCs) distributed among pleomorphic undifferentiated tumor cells. UCOGCP can occur either alone or in association with other types of pancreatic tumors.

Breast cancer associated with osteoclast-like giant cells (OGCs) refers to a morphological pattern of invasive breast carcinoma of non-special type. Their presence is sometimes subtle, but OGCs can be appreciated both histologically and immunohistochemically. The origin of OGCs as well as their implication for prognosis remain debated.

Tenosynovial giant cell tumors (TGCTs) arise from the synovium of joint, bursa, and tendon sheath. Diffuse type often affects large joints, has higher recurrence rates, metastases, and malignant transformation potential compared to the localized type. The cytopathology of TGCT, a fibrohistiocytic neoplasm distinct from other giant cell-rich soft tissue tumors, is rarely reported.
